Indian renewable energy developer Hero Future Energies has partnered with US-based Ohmium International on the development of green hydrogen plants in India, the UK, and Europe with a cumulative electrolyzer capacity of 1 GW.

Bluetti’s NA300 sodium-ion solar generator offers thermal stability, fast-charging capacity, low-temperature performance, and integration efficiency.

Researchers at Stanford University and the US Department of Energy’s SLAC National Accelerator Laboratory have explored the potential recovery of lost capacity in lithium batteries by using an extremely fast discharging step to reconnect an island of inactive lithium with the anode. Adding this extra step slowed the degradation of their test battery and increased its lifespan by nearly 30%.

The plant at its Jorhat oilfield in Assam will produce green hydrogen using anion exchange membrane (AEM) technology.

Huaneng Power International has switched on a 320 MW floating PV array in China’s Shandong province. It deployed the plant in two phases on a reservoir near its 2.65 GW Dezhou thermal power station.

Scientists at the Nankai University in China have provided a comprehensive overview of current research on silicon heterojunction-based tandem solar cells (SHJ-TSCs) and shared their expectations of future developments in this field.

The 52 kW containerized solution is being developed by German start-up Solarbakery. The bakery’s production process was adapted in such a way that the majority of electricity consumption is already incurred during the day and is only baked briefly in the dark before dawn.

Germany’s TÜV Rheinland is investigating how photovoltaics could be used for powering railway traction networks in a 14-month research project.

The device was designed by scientists in Portugal to optimize light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.

An international research team has examined combining solar power generation with energy-intensive hydroponic horticulture and has found that this may be a viable solution depending on project size and available incentive policies. Their approach considered various factors impacting PV system efficiency, including environmental factors, the type of solar array, and the electricity demand from the hydroponic farm.
