The business models and technologies underpinning the development of stationary energy storage markets are evolving rapidly. Dr. Kai-Philipp Kairies, Jan Figgener and David Haberschusz of RWTH Aachen University look at some of the key trends driving the sector forwards, in a paper which first appeared in PV Tech Power’s Energy Storage Special Report 2019.

Energy-Storage.news editor Andy Colthorpe shares his top takeaways from last week’s Solar Power International convention, incorporating Energy Storage International and hosted this year at the North American Smart Energy Week in Utah.

GE Renewable Energy, an arm of the US engineering giant, will supply 100MWh of battery energy storage systems (BESS) to three projects being developed by Convergent Energy + Power in California.

The huge upsurge in lithium-ion battery deployment expected over the next two decades poses a particular problem: what to do with cells that have reached the end of their useful life. Stefan Hogg investigates how lithium recycling will come into its own to handle spent batteries

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.

DC-coupling of combined solar and energy storage plants could be a more effective way to save energy that would otherwise be clipped and ‘lost’, benefitting the grid and helping efforts to reduce the amount of carbon pumped into the air, the COO of Fluence has said.

NEC will be using so-called ‘liquid metal’ batteries produced by Ambri in projects that could require more than four hours’ duration of energy storage, the company announced at SPI / ESI this week.

We’ve arrived at Day One of Smart Energy Week – hosting Solar Power International and Energy Storage International in Utah. Here are some of my observations: both on and ‘off’ the record.

Country part of Latin America’s lithium triangle will tap into sizeable reserves of sought-after metal to create industrial ecosystem, top official says at PV plant launch.

While sized only at 30kW, the successful installation of a battery energy storage system in Puebla, Mexico, is nonetheless being hailed as a milestone as it is claimed to be the first such system to deliver frequency regulation services in the country.
