News in brief from around the world in energy storage.

Mitsubishi Power has launched a simplified approach to commercially integrating hydrogen into energy systems either as long or short duration energy storage, or as a means of balancing the grid as higher shares of renewable energy are added.

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.

Centrica has formally announced the completion of its 49MW Roosecote battery storage project, 18 months after construction started.

A 3,000MW energy storage target, proposed in Arizona as part of a grid modernisation policy, recognises the role of the technology in reducing the need for fossil fuels to stabilise the grid, a consultant has said.

A community-owned utility company in California is preparing to install a large-scale battery system that could enable the addition of around 50MW of solar generation capacity to the local grid.
