The Hydrogen Stream: IEA says just 7% of planned capacity to go online by 2030
The International Energy Agency (IEA) says in a new report that only 7% of planned renewable-based hydrogen capacity is expected to go online by 2030. The report notes the need for consistent policies to support demand and prevent stranded assets.
‘Shallow defects’ key to high efficiency of perovskite solar cells, say researchers
Researchers at the Jülich Research Center in Germany have used novel photoluminescence measurements to analyze the recombination of charge carriers in perovskite solar cells. They have found that the loss of charge carriers in perovskite devices works differently from other types of PV cells.
Perovskite-silicon tandem solar modules must ensure degradation rate of 0.4%/year to compete with crystalline silicon
Researchers from Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) investigated the commercial prospects of perovskite-silicon tandem PV technologies and found that, in order to bring them closer to market maturity, their cost should not exceed by 30% that of crystalline silicon counterparts. Their roadmap stresses the importance of reducing perovskite degradation and improving product stability.
Scalable thermochemical energy storage for renewable energy
US-based RedoxBlox has developed thermochemical energy storage (TCES) technology looking to replace natural gas heating for industrial sites and provide the lowest-cost, grid-scale storage.
Phnix releases residential air-to-water heat pump
The Chinese manufacturer said its new propane heat pump has a seasonal coefficient of performance exceeding 5.0.
French startup offers new solution for green solar rooftops
Vegetek has developed a “biosolar” roof solution for new and existing buildings. It combines the benefits of greenery and solar panels.
Hybridizing residential ground source heat pumps with PVT, free cooling
Researchers in Sweden sought to raise the efficiency of ground source heat pumps by combining their operation with that of PVT systems and free cooling. Through a series of simulations, they found that this integrated solution may reduce borehole length and land area requirements.
Perovskite solar module based on new interconnection tech achieves 21.37% efficiency
Chinese solar perovskite specialist Mellow Energy and the Jinan University developed a new manufacturing process for perovskite solar modules that enables the formation of a protective layer at the interface between the perovskite absorber and the electron transport layer. This prevents the effusion of volatile components from the perovksite film.
Valmont Solar opens mounting system factory in Brazil
Valmont Solar says its new production facility boasts the largest tracker control system manufacturing unit in Brazil and will create more than 300 new jobs. The solar tracker specialist says the factory will serve as a vital supply hub for the Latin American market.
Fonterra reveals high-temperature industrial heat pump
Fonterra, a New Zealand-based dairy producer, has started operating a new heat pump in combination with a solar thermal facility. The hybrid project transforms excess heat from chillers and compressors into a heat source for industrial use.
