Cheaper batteries for domestic solar energy and grid-scale storage

As disturbing news piles up, so does news of the sort of positive developments covered on this site. Today’s post was going to be about the news that “as of the first of January this year, all public transport trains in the Netherlands are being powered by renewable energy” (wind) first brought to me by Futurism.

elon-muskThat subject is being set aside as it has been very widely covered in the MSM. So instead we turn to specific news about the work of Elon Musk (left), a co-founder of PayPal who is now chairman of Tesla Motors.

The FT reports that householders are starting to buy more battery storage systems as costs come down and consumer interest is rising in Tesla, the electric car company founded by Elon Musk, which is also making the Powerwall domestic battery.

“Tesla’s market entry has led to a surge of interest from the media and public alike in a way that rarely happens in the energy sector,” the UK Renewable Energy Association said in a report published earlier this week.

In February last year the Guardian reported that Mark Kerr became the first British owner of a Tesla Powerwall. Kerr and his family tend to be out at work and school when the sun is shining and the 16 solar panels on the roof of their home in Cardiff are producing power. The excess is fed into the grid and they make a return on it but they are not able to use the power from their panels.

However, from now on, energy produced but not used during the day will charge the Powerwall and provide them with the energy they need when they’re at home and their lights, music centres, computers, televisions and myriad other devices need feeding.

Jonathon Porritt – who recently wrote about the relatively low prices of solar tiles produced by Musk – gives a ‘wee glimpse’ into the transformative impact of cheaper storage technologies, on this video of a presentation by Tony Seba which focusses on their use in cars..

While cheaper battery storage offers potential benefits to renewable power stations and homeowners, industry analysts said that grid-scale storage could also produce large savings by reducing the need for new power stations and transmission lines.
