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.

Sales of battery storage units to residential households in Germany are booming, but it’s the value of services the batteries can provide, rather than the hardware itself that offers a long-term economic opportunity, a Siemens representative has said.

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.

With Brexit day less than a month away and still no certainty around what the final deal will look like, the time is now for the energy storage sector to prepare for every eventuality so it can play to its increasing strengths, writes Stephen Irish, co-founder of Hyperdrive Innovation.

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.

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.

The new mission focuses on local manufacturing across the whole supply chain for electric vehicles (EV) including battery and cell manufacturing while also supporting clean energy and storage uptake.
