Scientists in China have demonstrated a photovoltaic-thermal system that utilizes Tesla valves to increase cooling and efficiency. The system was found to have better performance compared to PVT systems made with several different cross-sectional structures.

A startup spun out of the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) has secured a grant to build a 5 kW electrolyzer that will be deployed at a UK power plant operated by French energy utility EDF.

UNSW scientists have suggested to use dual-fuel reciprocating engines for adding gas-to-power operations in large scale production of hydrogen based on PV power. The preliminary findings of their research show that the proposed system is still achieving a too high LCOE for commercial maturity. Decreasing electrolyzer costs, policy interventions and changing energy market dynamics, however, may more than halve the LCOE values in the future.

Eight of the 10 transmission corridors proposed by the US Department of Energy (DoE) could facilitate transmission between grid regions. One would expand transmission within the Mid-Atlantic’s PJM grid region, and one would expand transmission in the Northern Plains.

The Chinese manufacturer said the new product has an efficiency of up to 19.46% and a temperature coefficient of -0.30% per C. It is available in bright red, light gray, brown, green, blue-green, orange, and ocean blue.

An international research team developed a perovskite solar cell performance-boosting treatment based on phenethyl ammonium chloride (PEACl) that is also claimed to reduce the number of process steps. With this technique, the group built a champion device with a 20.9% efficiency.

Development of green hydrogen production in Europe is moving forward in fits and starts, but the ongoing World Hydrogen 2024 event in Rotterdam calls for blue hydrogen adoption, which suggests that the oil and gas industry aims to maintain control of the hydrogen market. 

The Austrian manufacturer said its new heat pump can achieve a seasonal coefficient of performance of up to 4.7 and flow temperatures of up to 75 C. It is available with sizes ranging from 2 kW to 7 kW.

Developed through bandgap engineering and material design, the proposed PV device relies on a tin-based perovskite material known as CsSnI3-xBrx. It can reportedly be further designed to achieve power conversion efficiencies exceeding 24%.

Scientists have investigated different techno-economic scenarios for using hydrogen storage in combination with hydropower and pumped hydro storage in Switzerland. They have found that hydrogen storage plays no major role under most conditions.
