While lithium-ion is rapidly racing ahead to become the “de facto grid storage solution” and is the most popular technology choice by far, vendors of other types of batteries are also targeting the market, with varying degrees of success.

Officials from 56 Muslim-majority nations have come together to pledge new climate-related technology goals that included promoting microgrids, energy storage and renewable energy targets.

It has been the US’ busiest quarter to date for behind-the-meter energy storage installations, driven in part by residential adoption in the advanced markets of California and Hawaii, GTM Research has found.

The UK’s Solar Trade Association (STA) has refuted claims made in a recent report that a residential solar array in combination with an energy storage system was not “economically viable”, calling it flawed and lacking in detail.

Swiss utility and power distribution company EKZ (Elektrizitätswerke des Kantons Zürich) is building a grid-balancing and renewables integrating 18MW / 7.5MWh energy storage system and has appointed NEC Energy Solutions to execute the project.

A village in the south east of the Czech Republic will be host to what is thought to be the country’s first grid-scale lithium-ion battery energy storage system (BESS) connected to a solar farm.

A not-for-profit utility cooperative from Texas has been awarded a contract to electrify a community in Liberia with a solar-plus-storage microgrid, to benefit around 400 homes and businesses.

Green Hedge, a UK renewable energy developer that has diversified into battery energy storage systems, has had an application for a 40MW project approved by local authorities in Derbyshire, England.

Using just 351.9kW of PV and 1MWh of energy storage in a microgrid, a tiny island off the Massachusetts coast successfully met more than 50% of its electricity demand over summer.

There is no economic benefit from installing energy storage with solar PV in UK homes, a new study has suggested, adding that the cost of battery degradation would cost homeowners £400 (US$518) in the first year.
