A 125 kW/500kWh storage unit will be tested by China’s National Photovoltaic and Energy Demonstration Experimental Center. The storage system will be provided by Canadian specialist VRB Energy.

Kent Kernahan has set out to take the heat out of solar cells. He and his partners may end up bringing solar manufacturing jobs to disadvantaged communities, while making low-cost rooftop solar more widely available.

According to a new study from the Massachusetts Institute of Technology, hydrogen-fired gas plants will compete with lithium-ion storage for seasonal storage and their competitiveness will strictly depend on the heat rate of the gas power plants they may replace.

Researchers from Melbourne’s Monash University have unveiled new machine learning technology which has already delivered a 45% improvement in the precision of power output forecasts at large-scale wind and solar farms and could potentially pave the way for increased renewable energy penetration in the grid.

Researchers at the Pacific Northwest National Laboratory have developed a revolutionary lithium-metal battery chemistry that could allow electric vehicle batteries to almost double their capacity, while also overcoming historic setbacks.

The generator can be combined with batteries, solar panels, or small wind turbines. It is based on a proton exchange membrane fuel cell technology and is claimed to have a minimum lifetime of 5,000 working hours.

Scientists demonstrated a perovskite-silicon tandem cell that reached 27% conversion efficiency. Though higher tandem cell efficiencies have been achieved, this represents a big jump in efficiency for those utilising n-i-p architecture, which previously had not surpassed 22%.

In his first public address, the newly appointed head of the Australian Energy Market Operator significantly upped the Operator’s ambitions for renewable penetrations in the grid, conveying the importance of no longer constraining what he called ‘zero cost’ renewable energy assets.

SA Water, one of the largest water utilities in Australia and most ambitious when it comes to renewable energy, has partnered with aerial solar inspection and data analysis company, Above, to monitor the performance of its 360,000+ solar panels.

An international team of scientists developed a technique to isolate individual sources of electrical ‘noise’ within a solar cell. Comparing the technique to being able to pick out a single voice within a 200-person choir, they say the technique will help to improve understanding of where efficiency losses occur within a cell, and effective ways to mitigate them.
