The evolution of energy storage and decarbonisation’s direction of travel are up for discussion in a podcast first posted just before the end of 2019.

This calendar year is almost finished and Solar Media Towers will shut down for a short break between 25th December and January, but we’re already looking ahead to a New Year – a New Decade – of the energy transition.

While recycling of lithium and other materials such as cobalt from batteries will greatly increase in the coming years, the potential availability of second life batteries should not be underestimated, according to new research and data.

By the middle of the 2020s, using hybrid ‘portfolios’ of batteries and renewable energy sources will economically outperform existing gas power plants, while the combination of technologies is already cost-competitive with building new gas plants, a new report from the US-based Rocky Mountain Institute has said.

New technologies and designs aimed at driving down the cost of energy storage facilities are currently the focus of intense industry R&D. Sara Verbruggen reports on DC coupling, an emerging system architecture that many believe will soon become the industry standard.

Energy Storage Special Report 2019, from the editorial teams behind Energy-Storage.news and PV Tech, brings you no less than seven feature articles and technical papers looking at everything from the policy and regulatory initiatives that still need to happen, to bankability and profitability of ESS, system technologies and architecture, all the way to recycling and end-of-life care for batteries.

A new white paper from Wärtsilä Energy shows that being able to integrate and then optimise all of these different assets is the key to ensuring that your project – and your investment – is going to provide the maximum benefit, longest possible lifetime in the field – and the best business case. Risto Paldanius, Director of Business Development, Energy Storage and Integration at Wärtsilä told us a bit more about what optimization really means in today’s energy market.

Schmid and Saudi companies are also planning a gigawatt-scale manufacturing facility for Vanadium Redox Flow Batteries.

Liquid air energy storage (LAES), so far only deployed at scale at two sites in England, will be available in a number of new territories after manufacturer Highview Power signed a deal claimed to be worth €1 billion (US$1.12 billion).

Homeowners across Afghanistan are set to benefit from the country’s first pay-as-you-go (PAYG) home solar systems combined with energy storage batteries, being delivered in a pioneering new programme.
