Rugeley coal plant to be transformed into a sustainable village

Rugeley coal plant to be transformed into a sustainable village


Powered by Guardian.co.ukThis article titled “Rugeley coal plant to be transformed into a sustainable village” was written by Adam Vaughan, for theguardian.com on Monday 19th November 2018 13.01 UTC

An old coal power station is set to be transformed into a “sustainable village” of 2,000 homes powered by solar panels, in the biggest redevelopment yet of a former UK power plant.

French firm Engie said it had decided against selling off the Rugeley site in Staffordshire and would instead build super efficient houses on the 139-hectare site as part of its bid to “move beyond energy”.

Half of the energy required by the new homes will come from green sources, predominantly solar, which will be fitted on rooftops, in a field and even floating on a lake.

The company is planning for 10 megawatts of solar capacity in total, equivalent to one of the UK’s smaller solar farms.

Batteries will be used across the site, both in homes and at a communal power storage facility, to balance out electricity supply and demand.

The firm is also claiming the homes will be so efficient they will use nearly a third less energy than average new builds. Heating will come not from gas boilers but electric devices such as heat pumps.

Wilfrid Petrie, Engie UK’s chief executive, said: “We are positioning ourselves as going beyond energy into place-making. It’s an example of us closing down our coal power plant and, instead of selling off the land, we’ve decided to regenerate it ourselves.”

Rugeley, which stopped generating electricity in the summer of 2016, is one of several coal plants to close in recent years due to economic pressures and environmental regulations.

There are seven operational coal power stations left in the UK, but all are due to shut by a government deadline of 2025, raising questions over what happens to the sizeable parcels of land afterwards.

While some energy companies are hoping to build gas plants on or adjacent to the old coal sites, others will need to be decommissioned for other uses.

In Shropshire, regeneration firm Harworth is planning to turn the 97-hectare brownfield site of a former power station into a development of homes and commercial units.

Engie said it was eyeing other sites around the country. “There’s a list of similar sites, which we are looking at. It’s not in the hundreds, but there are several,” Petrie said.

Peter Atherton, an analyst at Cornwall Insight, said putting local electricity generation at the heart of new housing projects was almost becoming a prerequisite for developers to get through planning.

“It is the way of the future. There is no doubt large scale housing developments going forward are going to have some form of local generation because it is all the craze,” he said.

Around 30% of the Rugeley project will be classified affordable homes, though it is not clear how much the green energy measures and high building standards will add to the upfront cost of the properties.

Consultation on the scheme starts this month, with construction due to start next year and demolition of the former coal plant – including the cooling towers – due to finish in 2020, with plans for the first people to move in the year after.

£60m ‘greenery drive’ to plant 10m trees in England

£60m ‘greenery drive’ to plant 10m trees in England


Powered by Guardian.co.ukThis article titled “£60m ‘greenery drive’ to plant 10m trees in England” was written by Adam Vaughan, for The Guardian on Monday 29th October 2018 18.40 UTC

More than 10m trees will be planted across England with the injection of £60m of new funding over five years, as part of what the government billed as its “drive to preserve the country’s greenery”.

The bulk of the money, £50m, will pay landowners for planting trees that lock up carbon, which observers said raised questions over how accessible those woodlands would be to the public. That fund, the Woodland Carbon Guarantee scheme, should pay for 10m trees.

The other £10m will be targeted at planting in cities and towns and should fund at least 100,000 more trees.

The Woodland Trust, a conservation charity, said the money was a step in the right direction in terms of tackling climate change and wildlife losses, but not enough in total. “The problem is greater than just having the funds to deliver increased tree-planting,” said Abi Bunker, the group’s director of conservation.

The government said it would also back a study into the possibility of creating a new “Great Thames Park” in the Thames estuary, which experts have said could be ready by 2020. Ministers have pledged to plant 11m trees between 2017 and 2022, approximately the same number that were planted under the five years of the coalition.

England’s tree-planting record is poor compared with other European countries. About 1.6m trees were planted in England with government support in the 2017-18 financial year, covering 895 hectares. By comparison, Scotland planted 7,100 hectares in the same period.

Conservationists have pointed out that because England’s 120m ash trees are threatened by ash dieback, a deadly fungus that arrived in 2012, the country is on track to suffer a net loss of trees over the next five years. The mix of species to be planted under the government’s new funding announcement will be decided at a later date.

Air pollution fears fuel fight against new London cruise ship terminal

Air pollution fears fuel fight against new London cruise ship terminal


Powered by Guardian.co.ukThis article titled “Air pollution fears fuel fight against new London cruise ship terminal” was written by Matthew Taylor Environment correspondent, for The Guardian on Wednesday 26th September 2018 10.30 UTC

A huge new cruise ship terminal planned for the river Thames would lead to a surge in dangerous levels of air pollution in the heart of the capital with unknown health consequences for hundreds of thousands of people, campaigners have warned.

Under the proposals, which have been given planning permission, up to 55 giant cruise ships would dock in London every year. Each ship would need to run its diesel engines round the clock to power onboard facilities, generating the same amount of toxic NO2 emissions as almost 700 continuously running lorries.

“As we find out more about the damage air pollution is doing to people’s health it is unthinkable that something like this can go ahead,” said local resident Laura Eyres, who is one of those leading the fight against the development.

“There is simply no justification for having these huge ships sitting here right next to busy residential areas and schools, belching out this level of pollution with all the associated damage to people’s health that have now been proven.”

Cruise ship pollution

There has been growing concern about the scale of the air pollution crisis in recent months. A slew of new research has highlighted the health risks associated with toxic air – from reduced intelligence to a rise in asthma deaths; heart disease to spikes in Alzheimer’s disease and dementia.

In London, the mayor, Sadiq Khan, has announced a range of measures including plans to introduce a low emissions zone banning the most polluting road vehicles from a large swath of the city from 2021.

However, the Thames does not fall under his jurisdiction and campaigners fear it has become a “wild west” in terms of air pollution.

“The fumes that are emitted on the river simply would not be allowed if they were coming from a road in London,” said Eyres. “It is really worrying to think what damage these fumes are causing local residents, and if the new terminal goes ahead that is only going to get a lot worse.”

The Port of London Authority (PLA) controls traffic on the Thames and admits the “marine sector” has lagged behind in terms of tackling air pollution.

However, it says it is catching up and earlier this year it produced its first air quality strategy. It points out that the Thames is only responsible for 1% of London’s air pollution and says emission levels will improve in the years ahead as clean marine technology comes into force.

Martin Garside from the PLA said it was working with the the mayor and local authorities “to secure strong environmental standards”.

He added: “With a single barge carrying the loads of 50 lorries – the Thames helps reduce traffic and pollution on London’s congested roads. Over four million tonnes of cargo is transported between river terminals – removing about 300,000 lorry movements from the roads.”

The proposed new cruise terminal at Enderby Wharf in Greenwich is owned by Morgan Stanley, which was given planning permission for the terminal and wider residential development by Greenwich council in 2012 and updated permission in 2015.

Now the council has changed its mind and is backing campaigners’ calls for Morgan Stanley to come up with a greener alternative for the cruise terminal.

Residents want it to be “zero emissions”, only allowing ships that can plug into an onshore power point so they can turn off their polluting diesel engines.

Eyres said: “With 55 cruise ships planned annually and each staying for three days we face huge amounts of sulphur dioxide, nitrogen dioxide and particulate matter being released into our homes every day of the summer with potentially devastating health implications.”

One of the big cruise ship companies, Viking, said its ships were already fitted with the “latest technology that meets the strictest environmental regulations”.

A spokesman added: “If shore side power were available then we would consider using it. In fact, we are already prepared to use shore power. Our newest ship, launched this year, has a built-in connection, and we are updating our other four ships to use shore power in order to have the capability fleetwide.”

Campaigners wrote to Morgan Stanley earlier this month raising their concerns again and arguing the current plans were at odds with the company’s stated commitment on environmental sustainability.

A spokesperson for the company said it had received the letter and was working on revised plans for the development.

“We acknowledge East Greenwich Residents Association’s concerns and can assure [them] that our new proposals will take these concerns into account.”

However, Eyres said local residents needed more than encouraging words. “We can’t rest until we see a concrete commitment from Morgan Stanley that their plans for a polluting cruise port are dead in the water.”

Recycled plastic could supply three-quarters of UK demand, report finds

Recycled plastic could supply three-quarters of UK demand, report finds


Powered by Guardian.co.ukThis article titled “Recycled plastic could supply three-quarters of UK demand, report finds” was written by Sandra Laville, for theguardian.com on Thursday 14th June 2018 05.01 UTC

Plastic recycled in the UK could supply nearly three-quarters of domestic demand for products and packaging if the government took action to build the industry, a new report said on Thursday.

The UK consumes 3.3m tonnes of plastic annually, the report says, but exports two-thirds to be recycled. It is only able to recycle 9% domestically.

Measures including increased taxes on products made with virgin plastic, and mandatory targets for using recycled plastic in packaging, could encourage an additional 2m tonnes of plastic to be recycled in the UK, the report from Green Alliance said.

The analysis said simply collecting plastic and sending it abroad for recycling does not solve the problem of the global scourge of plastic pollution.

“The UK does not have an adequate system to capture, recycle and re-use plastic materials,” the report said.

It recommends three new measures to ensure more plastic is recovered in the UK and used as raw material in manufacturing. These are:

  • Mandatory recycled content requirements for all plastic products and packaging;
  • Short-term support to kickstart the plastic reprocessing market; and
  • a fund to stabilise the market for companies investing in recycling plastic domestically.

Green Alliance produced the report for a group of businesses that have formed a circular economy taskforce.

Peter Maddox, director of Wrap UK, said the UK had to take more responsibility for its own waste.

“Our mission is to create a world where resources are used sustainably. To make this happen in the UK, we need to design circular systems for plastics and other materials that are sustainable both economically and environmentally. This will require some fundamental changes from all of us.”

The report said government action is necessary to create and support a secondary plastic market in the UK. “The government is uniquely placed to address the market failures that have led to unnecessary reliance on virgin materials to the detriment of the environment, industry and the economy.”

UK businesses including supermarkets recently signed up to a pact to cut plastic.

But voluntary pacts were not enough, the report said, and government action was needed.

“A secondary plastic market … could recycle an additional 2m tonnes in the UK and fulfil 71% of UK manufacturing’s raw material demand … Voluntary initiatives like the UK plastic pact … only thrive when supported by a credible prospect of government regulation if industry does not deliver.”

Will the Labrador energy switcher make you switch suppliers?

Will the Labrador energy switcher make you switch suppliers?


Powered by Guardian.co.ukThis article titled “Will the Labrador energy switcher make you switch suppliers?” was written by Adam Vaughan, for The Guardian on Sunday 11th March 2018 16.13 UTC

A device that plugs into a home broadband router and automatically switches supplier when cheaper deals become available is set to revolutionise the home energy market.

The launch of Labrador comes as more and more people are changing their energy companies.

The company’s free service is primarily targeted at the growing number of households which have smart meters, which automate readings. More than 8m have been installed in the UK so far, and energy suppliers have to offer one to every home in the UK by the end of 2020.

Unlike conventional price comparison sites, which require people to actively search for a better deal and input their details and energy use, Labrador will automatically switch people’s accounts when it finds a cheaper tariff.

Jane Lucy, founder and CEO of Labrador, said: “We’re not about behaviour change: we assume consumer lethargy will remain.”

Flipper is a similar service that launched in 2016, relying on accessing a customer’s energy bills, which might be estimated. Labrador believes it will be more accurate, as it use a device that plugs into a customer’s broadband router and talks wirelessly to their smart meters, taking readings direct from them.

While Flipper charges an annual £25 fee, Labrador makes its money like a switching site, by being paid an acquisition fee by suppliers.

Lucy said she expected customers would be switched 1-3 times a year and save on average £300 a year. They are given the choice to tailor their preferences, for example, to just green energy tariffs.

The company has signed up about 500 customers since a soft launch in February, but aims to take 3% of the switching market within five years. In the future the company may branch out into home automation and helping consumers identify individual energy-guzzling appliances, Lucy said.

An eco-friendly cuppa? Now teabags are set to go plastic-free

An eco-friendly cuppa? Now teabags are set to go plastic-free


Powered by Guardian.co.ukThis article titled “An eco-friendly cuppa? Now teabags are set to go plastic-free” was written by Rebecca Smithers, for The Observer on Sunday 28th January 2018 00.04 UTC

The war on plastic waste is extending to the UK’s favourite beverage, with a major retailer in the final stages of developing a fully biodegradable paper teabag that does not contain plastic.

The Co-op is to make its own-brand Fairtrade 99 teabags free of polypropylene, a sealant used industry wide to enable teabags to hold their shape, and the guilt-free brew is due to go on sale by the end of the year.

The scale of the problem is huge. According to the trade body the UK Tea and Infusions Association, teabags account for a whopping 96% of the 165 million cups of tea drunk every day in the UK. Anti-plastic campaigners have been appealing to consumers to use loose tea or “greener” options such as Japanese-style “pyramids” made of 100% compostable corn starch, but these are more expensive than mainstream mass-produced teabags.

The Co-op, which sells 4.6m boxes of tea a year (367m teabags) has joined forces with its tea supplier, Typhoo, and Ahlstrom-Munksjö – specialists in sustainable fibre solutions – to develop a method of heat-sealing bags to eliminate the more widely used plastic seal.

The biodegradable bag will undergo rigorous testing next month and could be on shelves later this year. It is intended to be rolled out across the Co-op’s entire own-label standard tea range and will be fully compostable in food waste collections.

“Many tea drinkers are blissfully unaware that the teabag from their daily cuppa is sealed using plastic,” said Jo Whitfield, chief executive of Co-op Food. “Even though it’s a relatively small amount, when you consider the 6bn cups of tea that are brewed up every year in the UK, we are looking at around 150 tonnes of polypropylene – that’s an enormous amount of accumulated plastic waste that is either contaminating food waste compost collections or simply going to landfill.”

But the UK Tea and Infusions Association warned of higher prices for consumers. A spokesman said: “The UK tea industry has been experimenting with non-plastic sealing methods, but those methods are costly. The raw material cost and upgrades to machinery would increase the cost of a bag by about eight times if we were to move to a non-plastic sealing procedure now. We know that a significant price rise would have a severely negative effect on sales and seriously reduce the income of farmers from some of the poorest tea-growing regions of the world.”

Tackle UK’s plastic bottle problem with money-back scheme, ministers told

Tackle UK’s plastic bottle problem with money-back scheme, ministers told


Powered by Guardian.co.ukThis article titled “Tackle UK’s plastic bottle problem with money-back scheme, ministers told” was written by Matthew Taylor and Sandra Laville, for theguardian.com on Tuesday 4th July 2017 05.00 UTC

The UK government is under growing pressure to introduce a money-back return scheme for plastic bottles, in order to tackle huge volumes of waste in a country where 400 bottles are sold every second.

Opposition parties have called on ministers to introduce a deposit return scheme that experts say would drastically reduce the number of plastic bottles littering streets and seas around the UK. Similar schemes have been successfully introduced in at least a dozen countries.

The idea has the backing of global drinks company Coca-Cola and comes amid warnings that the worldwide plastics binge poses as serious a threat as climate change.

Sue Hayman, Labour’s shadow environment secretary, urged the government to take swift action. “A deposit return scheme would have widespread public support and would go a long way to ensuring that we recycle as much of our waste as possible,” she said.

Kate Parminter, environment spokesperson for the Liberal Democrats, said momentum was growing behind calls for a deposit return scheme. “Earlier this year, Coca-Cola said to the Scottish parliament they would back a well-designed deposit return scheme,” she said. “Now that industry are backing this scheme, it is high time the UK government began to throw their weight behind it.”

Last week, new figures obtained by the Guardian established that a million plastic bottles are bought around the world every minute and the number will jump another 20% by 2021.

Chart

According to an unpublished parliamentary report, more than 4m plastic bottles a week could be prevented from littering streets and marine environments in Britain if authorities adopted the kind of deposit return schemes that operate in countries like Germany and Australia.

The Conservative party’s manifesto did not mention such a scheme in the run-up to last month’s general election, but a spokesman for the Department for Environment, Food and Rural Affairs said the idea was being considered as part of a wider litter strategy launched in April.

“We have made great progress in boosting recycling rates for plastic bottles, with their collection for recycling rising from less than 13,000 tonnes in 2000 to over 330,000 tonnes in 2015,” the spokesman said. “We are considering further the practical ways in which we can deal with the worst kinds of litter, including plastic bottles.”

However, Caroline Lucas, MP for Brighton Pavilion and co-leader of the Green party, said ministers must do more.

“The government is under growing pressure to take action on the plastic bottle crisis,” she said. “With such a slender majority in the House of Commons, and with the public swinging behind the campaign against plastic waste, there is a real chance that ministers will consider introducing a bottle deposit scheme.

“For a government desperate to salvage its reputation, taking such a simple step forward isn’t just the right thing to do – it serves their self-interest too.”

In Scotland, support is growing for a deposit return scheme. Last week, the Scottish National party launched a detailed study into how such a scheme for bottles and cans would work.

Roseanna Cunningham, the Scottish environment secretary, said: “Clearly there are a number of issues for the Scottish government to consider when it comes to deposit return schemes, which can only be addressed by carrying out work to understand the design of a potential system.”

Recycling rates for plastic bottles in Britain stand at 59%, compared with more than 90% in countries that operate deposit return schemes, such as Germany, Norway and Sweden.

Coca-Cola in Britain and Europe has made a U-turn on deposit schemes and now supports their adoption in the UK, after pressure from environment and anti-waste campaigners. “We believe a new approach is needed,” the company said in a report to the environmental audit committee before its inquiry into plastic bottles was dropped after the dissolution of parliament.

“From our experiences in other countries, we believe a well-designed, industry-run drinks container deposit return scheme could help increase recycling and reduce littering,” Coca-Cola added.

Between 5m and 13m tonnes of plastic end up in the world’s oceans each year, to be ingested by sea birds, fish and other organisms, and by 2050 the oceans will contain more plastic by weight than fish, according to research by the Ellen MacArthur Foundation.

Campaigners say plastic is polluting every natural system and an increasing number of organisms on the planet, with some of it already finding its way into the human food chain.

Government support needed to unlock billions in green business, says industry

Government support needed to unlock billions in green business, says industry


Powered by Guardian.co.ukThis article titled “Government support needed to unlock billions in green business, says industry” was written by Fiona Harvey Environment correspondent, for theguardian.com on Sunday 4th June 2017 15.59 UTC

The UK could be a green business powerhouse in the next three decades, but only if given proper support by government, a group representing more than 30 low-carbon companies has said.

The low-carbon economy in the UK employs at least 432,000 people, with a turnover of more than £77bn in 2015. This is larger than industries such as car-making and steelmaking, which are frequently given the spotlight when politicians discuss industry and jobs.

Growth in green business is also expected to outstrip other sectors of the economy, as international opportunities open up for low-carbon goods and services. Investments by major developing countries alone are projected to be tn by the end of the next decade, with green business’s supporters arguing that the UK is well placed to take a share of the burgeoning market.

In a letter to the Guardian, a group representing more than 30 of the UK’s green and low-carbon companies forecast that the low-carbon economy would rocket from 2% of the UK’s GDP today to 13% in the next three decades, boosting both manufacturing and services, but only with government support.
The business leaders urged politicians across the spectrum to respond, as the policies of the next government will play a major role in determining how the sector develops and whether job opportunities are realised. They wrote: “Stable policies to grow the UK’s low-carbon market will be essential to turn this potential into reality and ensure our economy remains competitive on the global stage.” Green businesses have been disappointed by the apparent lack of interest in the sector during the general election campaign, and by the absence of strong public commitments in the manifestos. The signatories to the letter concluded: “We call on the new government to put in place ambitious and long-term policies to tackle climate change and improve the state of the environment at the heart of its industrial strategy and vision for the UK.” The letter was coordinated by the Aldersgate Group and also signed by 11 companies including Kingfisher, Aviva Investors, Anglian Water, Siemens, and Scottish and Southern Energy. Nick Molho, executive director of the Aldersgate Group, said the decision by US president Donald Trump to withdraw from the Paris agreement on climate change would not make a major dent in the prospects for growth.
He noted that the shift to a more efficient and lower carbon economy is well under way across the globe, with the cost of clean technologies, such as renewable energy and electric vehicles, falling rapidly, and investment growing strongly. “Following the commitments made by six world leaders at the recent G7 summit, and the news of greater cooperation between China and the EU on climate change, major global players like the UK must continue to build competitive, low-carbon economies and honour their commitments under the Paris agreement.”
Environmental businesses in the UK have been hit in recent years by swings in government policy that have led to job losses and uncertainty among potential investors. These swings include the scrapping of subsidies and harder planning requirements for onshore wind farms; the slashing of support for solar panels and restrictions on solar farms; the abandonment of the “green deal”, which was intended to boost home insulation; the removal of the promised £1bn funding for carbon capture and storage facilities; and the scrapping of the target to make new homes zero-carbon.
Last week, Labour accused the Conservative government of failing to come up with plans on how to achieve the statutory targets on reducing carbon dioxide emissions, set out under the Climate Change Act. Green groups fear that a new Conservative government under Theresa May could scrap the Climate Change Act, leaving the UK without firm targets on cutting greenhouse gases. However, the government has pointed to increased investment for electric vehicles, support for new nuclear power stations, and a boost to offshore wind as evidence of its commitment to low-carbon infrastructure.

Since May 2010, the UK has installed more than 11GW of wind power, generating enough electricity for more than 7.8m homes.

The innovators: looped water system for Earth friendly shower

The innovators: looped water system for Earth friendly shower


Powered by Guardian.co.ukThis article titled “The innovators: looped water system for Earth friendly shower” was written by Shane Hickey, for The Guardian on Sunday 21st February 2016 09.00 UTC

When he was working on an academic project with Nasa, Mehrdad Mahdjoubi, a Swedish industrial designer, realised there could be parallels between sustainability in space and on Earth. The extremes of space required that the vital resource of water be used in the most efficient way possible. Water should also be used like this in the home, he thought.

Inspired by those experiences with the space agency, Mahdjoubi created a shower system that reuses the same water in a circular loop, while two filters take out impurities as it circulates.

This Shower of the Future , from his company, Orbital Systems, can operate on five litres of water. The water constantly circulates for 10 minutes or so – the time of an average shower – in turn saving also on energy.

“The reason that we make it work sustainably in space is because we have to do it,” the Swedish industrial designer said. “What if we try the same things on Earth … [if] the house was like a space capsule, how would we go about it? The most sustainable lifestyle is the one that we have in the most extreme environments and that may be in space or in a submarine where you actually have no choice but to really care for the resources that you have.”

Mahdjoubi said that while savings have been made in how water is used in toilets and washing machines, the same was not true of the shower. “Without changing the technology, we seem to just heat up water and put it down the drain,” he said. In Sweden, where the company is based, the average shower emits 15 litres of water a minute. During a 10-minute shower this amounts to 150 litres, he said.

The Orbital Systems shower starts with five litres of water and adds more if some is splashed out or is taken out of the system by the filters.

Water is first pumped through two filters, one which takes out larger particles such as sand, skin and dust and then a finer filter to extract bacteria, viruses and blood.

From there the water travels through a heater that moderates the temperature, which is set by a wheel control the user can change from hot to cold. The water then exits the shower nozzle as normal.

But when the water trickles through the drain it goes through a sensor which analyses it. If it is contaminated, the sensor recognises this and replaces the water.

The company says water flows at a rate of 20 litres a minute, compared to conventional showers, which typically range between seven and 12 litres a minute.

The shower takes in water from the mains until it senses that there is enough to go in a constant loop, said Mahdjoubi. “Even though the water is clean we would always flush it out before the next user. Comparing [it] to a hot tub where you sit in your own dirt for however many minutes, this is way more hygienic. When you stand in front of one of these showers you completely forget that the water is being recycled. It is the most unremarkable thing.”

The shower unit can be fitted as either an integrated system in the floor or as a standalone cabin with glass walls. The first units were delivered in December with most of the sales to commerical customers such as gyms, residential homes, swimming pools and the Swedish military. Nursing homes and hospitals have also bought them, said Mahdjoubi, because of the filter system.

“Not because they really want to save a lot of water but because you can guarantee that the water is clean and free from Legionnaires’ disease because it is always being filtered.”

How much money is saved depends on the cost of water and energy and how often the shower is used, he said. The company claims that a UK home can save £1,100 a year assuming there are four showers taken a day lasting nine minutes each.

Offsetting this is the price of the shower. The cheaper of the two residential units, where the shower is integrated into the floor of the bathroom, costs £3,300 while the standalone cabin costs £4,100.

As sales increase, Mahdjoubi said, the price would fall to less than £2,000 in three years. “I would say that we are steadily going down in price but we have to start where the market can afford it, that is why we have this premium and commercial focus we have right now,” he said.

A family would need to spend an average of about £110 every year replacing the purification capsules.

So far hundreds of the showers had been sold, said Mahdjoubi, and there had been particular interest from Denmark (location of one of the highest water prices in the EU) and from California, where there had been persistent droughts over recent years.

Australian homes among first to get Tesla’s Powerwall solar-energy battery

Australian homes among first to get Tesla’s Powerwall solar-energy battery


Powered by Guardian.co.ukThis article titled “Australian homes among first to get Tesla’s Powerwall solar-energy battery” was written by Oliver Milman, for theguardian.com on Friday 18th September 2015 03.08 UTC

Australia will be one of the first countries in the world to get Tesla’s vaunted Powerwall battery storage system, as several other companies scramble to sign up Australia’s growing number of households with solar rooftops.

US firm Tesla said that its 7kWH home energy storage units would be available by the end of the year in Australia, ahead of previous predictions it would arrive in 2016.

The Powerwall is a unit that sits on an interior wall. It has a lithium-ion battery, used to store energy created by solar panels on the household roof.

Tesla, which also makes electric cars, is the most high-profile company in the emerging battery storage industry – an area that is seen as crucial in making intermittent renewable energy such as solar and wind into a reliable accompaniment, or even alternative, to fossil fuel-fired power grids.

Canberra-based firm Reposit Power, which enables people to directly buy and sell their stored electricity, has partnered with Tesla for Powerwall’s launch.

There are a handful of existing Australian alternatives to the Powerwall, such as Redflow, headed by Simon Hackett, who founded Internode. Hackett also sits on the board of the NBN.

“Tesla’s arrival is important because they have such a high profile,” said Prof Anthony Vassallo, a sustainable energy expert at the University of Sydney. “The Tesla product isn’t unique by any stretch, but it’s the Apple brand of the battery storage industry, they have the sex appeal that others don’t.

“Solar PV and batteries are such a wonderful combination. Australians have demonstrated they are quite happy to purchase PV systems, Australia has a great solar resource and to have a battery to store that makes a lot of sense.

“There are packages of PV and batteries being offered by retailers and, as prices come down, we’ll see a lot more of this. Tesla’s price point in the US – of about US,000 (,173) – would be competitive here, it will sharpen up the players to make more efficient and higher-performing systems.”

Vassallo pointed out that the technology still has some way to improve – a 7kWH system will store little more than an hour’s electricity generated by a typical 5kWH solar system, meaning that some people may have to have several Powerwall, or equivalent, systems on their walls.

“I’d be wary of claims that people can go entirely off the grid, but it’s a first step,” he said. “Australia has high electrity prices, and once the price is acceptable I think the take-up will be strong.”

There are more than 1.3m households in Australia with rooftop solar, with the number increasing rapidly as the price of PV systems tumble. State-based tariffs have been gradually withdrawn across the country, while the federal government announced in July that it would instruct the Clean Energy Finance Corporation to favour large-scale solar over rooftop solar in its funding decisions.

Labor has set a target of Australia generating 50% of its electrity from renewable energy by 2030, although has provided little detail on how this would be achieved. The prime minister, Malcolm Turnbull, said the goal was “reckless” as the cost of it has not been quantified.

Vassallo said, “Australia could reach that 50% target, it just requires well-designed policies and markets that allow a transition from centralised, large-scale fossil fuels to efficient but variable renewables.

“Storage is a key part to make that happen. The beauty of renewables is that once you’ve managed the capital cost, there is no fuel cost. There’s an energy security there you don’t get with fossil fuels.”
