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.

Walking around Energy Storage Europe this year it was obvious that the show, like the market, has grown from a small handful of “strong believers” as one source put it, to a forward-looking show focused on a ‘business-as-usual’ scenario.

NextEra Resources will build a 100MW solar farm for Arkansas utility Entergy Arkansas, to include 30MW of battery energy storage, as Entergy seeks to build out solar capacity in the state.

Unlike the solar PV sector where there’s often an attitude of “let’s sell the project first and worry about O&M later,” storage projects must have services built in to the thinking and financial process from the beginning. With storage, a strong O&M plan and team become part and parcel of making and closing a strong productive deal, NEXTracker’s Marty Rogers argues.

The future of vanadium flow machine company redT has been plunged into doubt after it launched a strategic review of its ongoing business.

Nippon Koei, one of Japan’s largest engineering firms, has formed a joint venture with a British battery storage firm to construct two 50MW behind-the-meter energy storage projects in the UK.

The Asian Development Bank (ADB) has agreed to part-fund a US$53.2 million undertaking to power Tonga with renewable energy, including the installation of 22.2MWh of energy storage.

Saba Electric Company, sole supplier of electricity to the Dutch Caribbean island of Saba, celebrated as the island ran on 100% solar for the first time ever this month, with the switch-on of a solar-plus-storage microgrid.

This year’s Energy Storage Europe event marked something of a culmination of “more or less 10 years of continuous evolution” in the industry, Energy-Storage.news has heard.

In the hierarchy of grid needs, peaking power is often a priority in terms of providing resiliency and balance to the network. This is usually provided by natural gas turbines, which come at a high environmental and economic cost. Andy Colthorpe charts the rise of the solar-plus-storage peaker plant.
