Energy Storage

Storing oversized large scale PV with molten salt storage

Scientists from Israel and France have proposed a PV-plus-thermal-storage (PV-TS) concept that may be applied in regions with low direct solar beam radiation and high levels of global solar radiation. They estimated that the grid penetration rate of a large scale PV plant, when combined with molten salt storage, may rise from around 30% to up to 95%.

Iconic investor signs up for world-first domestic hydrogen battery in Australia

Gowing Bros has become the first major customer of the LAVO 40 kWh battery in Australia. The system, which features an electrolyzer and domestic fuel-cell tech, will be market-ready in June.

Big interest in Australia’s proposed 1.5 GW solar-wind-hydrogen hub

The Western Australian government has called for expressions of interest for its proposed 1.5 GW solar-wind-hydrogen hub at the Okajee Strategic Industrial Area. This week, it said that 65 companies from around the world are interested.

UK added 545 MW of solar last year to hit 13.9 GW

The news comes on the day a private equity investor in the English North East announced plans to jointly develop a 1.4 GWp solar portfolio with Canadian Solar.

The Indian market for off-grid solar refrigeration

Standalone solar-powered refrigerators present a $20 billion opportunity in India for vaccine storage, milk chillers, households, micro enterprises, and cold storage for farm produce, according to a new report by Gogla.

Improving PV-powered water electrolysis with external fields

Australian researchers have analyzed different ways to improve the efficiency of PV-powered water electrolysis for hydrogen generation. They include the use of magnetic fields, light energy, ultrasonic fields, and pulsating electric fields. Energy costs remain prohibitive, but molecular movement and the redistribution of molecules in water during electrolysis could open a path to viability.

Jenny Chase predicts up to 194 GW of solar this year

Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.

The best redox flow battery tech

Batteries based on vanadium or zinc bromide represent the cutting edge of redox flow storage tech, an international research team has claimed. They have identified challenges and opportunities for about a dozen redox flow storage technologies, while providing estimates of their current and projected levelized costs of storage.
