Water-based electrolyser for green hydrogen production

U.S. company Verdagy has secured a US$25 million (AU$35 million) investment for its new electrolyser technology, which provides hydrogen fuel for heavy industrial applications. The membrane-based technology uses large active area cells, high current densities, and broad operating ranges to deliver hydrogen at scale.

Next-gen concentrated solar power now under development in US

In new studies led by researchers from the National Renewable Energy Laboratory, the US Department of Energy pursues an energy cost goal of US$0.05 per kilowatt-hour.

‘Solar and wind deployment could not now be stopped if we wanted to’

BloombergNEF’s Jenny Chase has surveyed the state of affairs in world solar for clean energy journal Joule and said the technology’s historic ability to surmount obstacles – and persistently confound analysts’ predictions – should offer a reason for hope.

U.S. President provides backing for Brisbane-based EV charging company

Australian electric vehicle charging powerhouse Tritium continues to make inroads in the international market with United States President Joe Biden providing his backing for the company after it announced it will develop a new DC fast-charger manufacturing facility in the southern state of Tennessee.

Grazing animals increase carbon sequestration by up to 80% in PV projects

Temple University researchers have found that managed sheep grazing on an acre of recovering agricultural soil with native plants may sequester 1 ton of carbon per year, which could accumulate for 12 to 15 years before reaching saturation.

Forget batteries, what if surplus renewable energy could be stored as information?

A pair of researchers from the University of California San Diego have proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.

Microgrid project using vanadium redox flow battery

SDG&E and Sumitomo Electric complete a pilot microgrid project in California that successfully powered utility customers solely with energy stored in a flow battery.

The panel and the city

U.S. researchers have investigated how rooftop PV systems may affect air and building temperature in urban environments and, conversely, how the urban heat island (UHI) effect may have a negative impact on PV system performance. Their work considered urban air temperature, urban air pollution, the partial shading of the PV system, soiling, building heating and cooling loads, and outdoor shade.

Tesla Energy results up, but mixed, for 2021; solar makes nary a sound on quarterly call

On the company’s Q4 earnings call, the world-leading EV manufacturer again prioritised delivering cars over growing low-margin energy storage products, while solar products were barely noted. Both verticals grew though, solar by 68% and storage by 32%.
