China powers up world’s largest liquid air storage project
The 60 MW/600 MWh storage project is co-located with a 250 MW photovoltaic plant allowing for a high level of green energy self sufficiency.
Growing agri-PV tomatoes while producing hydrogen for smart windows
Scientists have simulated a residential building based on a real double-story house in the United Kingdom, combining rooftop agrivoltaics with onsite hydrogen production. Electricity generated by the solar system is used to produce hydrogen, which is then supplied to a hydrogen vehicle and insulated gasochromic smart windows.
How to improve indirect-expansion PVT-assisted heat pump performance
Scientists in Thailand have simulated an indirect-expansion photovoltaic-thermal-assisted heat pump and measured its performance under various cold water temperatures and tank sizes.
PV redox flow battery with 4.2% solar-to-electricity conversion efficiency
Scientists in China have constructed and tested a device that uses redox couples paired with a single triple-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating one sun, the device achieved an average solar-to-electricity conversion efficiency of 4.2%.
Saatvik Green commissions 2 GW EPE film manufacturing facility
Saatvik Green Energy has commissioned a 2 GW in-house EPE film manufacturing facility at its Ambala campus in Haryana.
Carmaker uses repurposed EV batteries to help power production plant
Repurposed electric vehicle batteries have been used for the energy storage component of a solar and battery project that is now helping power operations at carmaker Nissan Australia’s aluminium casting plant in Victoria.
Remote sensing-based tech for hourly snow-induced PV power losses assessment
A team of Sweden-based researchers has developed a snow loss model to estimate snow-induced PV power losses on an hourly basis. The proposed approach relies solely on data from remote sensing sources, such as aerial imagery, LIDAR, and satellite data.
Aiko achieves 34.76% efficiency for 2-terminal perovskite-silicon tandem solar cell
The Chinese manufacturer said its 2-terminal 34.76%-efficient perovskite-silicon tandem lab-scale cell is based on heterojunction technology and developed by a collaboration of Solarlab Aiko Europe, Aiko headquarters, and its R&D in Yuwi, China.
Solar glare forces panel removal at Amsterdam Airport
Glare from a nearby solar park forced temporary runway closures at Amsterdam Airport Schiphol, prompting Dutch authorities to order the removal of about 78,000 PV modules and apply anti-reflective film to others. The solar park operator, however, decided to replace all the panels. The largest portion of the removed, near-new modules have since been acquired by BM Energy and are expected to be redeployed in projects where glare is not a concern.
Off-grid floating PV-desalination system for hydrogen production
Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a hydrogen storage tank. Operation of the system in Oman could potentially yield a levelized cost of electricity of $0.05/kWh and a levelized cost of hydrogen of $9.5/kg.
