Many of the most polluting thermal power plants on the US grid today are also the most lucrative to run, but the service they provide could already be done twice as cheaply using solar and storage, developer 8minutenergy has claimed.

A large tranche of utility-scale solar – and storage – projects in Hawaii has been approved by the state’s Public Utilities Commission (PUC), each quoting a cost per kilowatt hour of US$0.10 or under.

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).

A key missing piece in the clean energy puzzle is the question of how to provide baseload power in an electricity system dominated by intermittent renewables. Javier Cavada of Highview Power examines cryogenic long-duration storage as a possible solution.

UK company Solarcentury has commissioned two solar-storage-diesel mini-grids in rural communities in Eritrea that are far away from the grid and have relied purely on diesel power until now.

French energy giant teams up with Myanmar-focused off-grid energy specialist, Mandalay Yoma, to help spur rural electrification across the Southeast Asian country with mini-grids combining PV, diesel and battery storage.

A recycling process for lithium-ion batteries already up and running, by Finnish state-owned energy services company Fortum could make dramatic reductions in their environmental footprint, the company has said.

24M, spun out of an MIT laboratory, claims its latest semi-solid battery ‘breakthrough’, Dual Electrolyte technology, heralds a new era to come for advanced lithium batteries. Andy Colthorpe spoke to some of the company’s leadership team to find out more.

Norwegian utility Statkraft has partnered with flow machine specialist redT on a fully-financed solar-plus-storage offering for the UK’s thriving C&I renewables market.

24M, a startup battery company founded as a spin-off from MIT, claims it has made a breakthrough in creating semi-solid lithium-ion battery cells with an energy density exceeding 350Wh per kg.
