Energy Storage

Elsewhere, the Danish government announced a plan to deploy up to 6 GW of electrolyzer capacity by 2030 and Germany and Norway agreed to conduct a feasibility study on large-scale hydrogen transport, including via pipeline.

A Dutch-Danish research group has provided a proof of concept for the use of Blatter radicals in electrochemical energy-storage applications. It tested these compounds in a small electrochemical cell that was found to remain stable over 275 charge/discharge cycles.

According to the new provisions introduced by the French government, owners of PV systems with a capacity of up to 500 kW will pay a grid fee that is 40% of the current rate. As for heat pumps, their owners will pay only 20% of the fee.

For short-term storage in a 100% renewables grid, thermal energy storage located at concentrating solar power plants could compete with batteries, according to a new study using an idealized grid model. Seasonal storage needs could best be met with power-to-gas-to-power technology.

The Slate solar and storage project began development in 2015 and is now one of the largest facilities of its kind in California.

The international development entity has already invested $1 billion in local, off-grid electricity networks over the last decade – and attracted a further $1.1 billion in matched funding – and has predicted mini-grids could supply electricity to 490 million people by 2030.

With polysilicon production capacity having been rapidly rolled out after last year’s shortages, China analyst Frank Haugwitz has suggested global manufacturing capability for the ethylene vinyl acetate used on PV panels could struggle to keep pace with what is expected to be another record year of demand for solar.

A decade on from energy rationing, head of state Sheikh Hasina is poised to announce the achievement of an historic goal which has been made possible with the help of off-grid photovoltaics.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh.

A report published by Irena hints the world’s politicians will have to get to work immediately to avoid another generation of fossil fuel-fired hydrogen, ammonia, and methanol plants being set up to run into the second half of the century.
