Energy Storage

Australian researchers have tested a novel lithium salt for high-voltage lithium batteries in electric vehicles and grid-scale storage systems. They claim the salt is less hazardous than conventional battery materials.

U.K. business and energy secretary Kwasi Kwarteng has unveiled a new hydrogen strategy aiming at developing both the green and blue forms of the fuel. Furthermore, Thierry Breton, the EU commissioner for the internal market, has said Europe needs to increase its commitment to hydrogen and use nuclear to produce a decarbonized form of the gas.

The race to electrify passenger cars is picking up pace, writes Prachi Mehta, senior research analyst for Wood Mackenzie. Competition among leading EV automakers is fierce, as 2024 looms as a watershed year when auto battery-pack prices cross a key consumer threshold.

Residential solar installation price declines have accelerated over the past year in the U.S. solar market. However, energy storage pricing has gone up, with Enphase taking an increasingly larger share of the market.

The switch from fossil fuels and nuclear will bring a jobs dividend thanks to the greater labor-intensity of renewables plants, according to a paper published by Finland’s LUT. However, the jobs dividend is unlikely to be evenly spread around the world, with Europe set to be a big winner.

The PV-powered geothermal heat pump system was tested for a year, with measurements taken by Researchers at the University of Nottingham. The UK group showed it was able to maintain an indoor temperature over 16 Celsius degrees in all seasons, except for winter.

As solar and wind make up larger portions of the energy mix, energy storage is becoming an increasingly important piece of the puzzle in keeping electricity networks running smoothly. And as battery costs fall, new business models are emerging to increase the value of battery energy storage projects for both grid operators and project owners. Focusing on two leading countries – the United Kingdom and Australia – pv magazine looks at what’s in store for large-scale energy storage.

Oman is expanding its network to become a hydrogen hub and the Massachusetts Institute of Technology (MIT) has published a practical guide for generating hydrogen using scrap aluminum. Furthermore, BP and Mitsui have separately announced more blue hydrogen projects.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

U.S.-based Xos offers a mobile charging station for commercial electric fleets, in order to provide power without making fixed infrastructure upgrades.
