Producing the goods
Germany’s Fraunhofer Institute for Solar Energy Systems (ISE) is demonstrating how a solar-powered refrigeration unit and dryer could be self-sustaining and improve food security in Kenya.
PV-powered underground heat exchanger for buildings
Researchers in India have designed a PV-powered earth-to-air heat exchanger to provide buildings with space heating and cooling. They say the proposed system could result in an annual energy gain of 8116.7 kWh.
Bslbatt unveils 89-mm-thick battery for residential solar
China’s Bslbatt has added a rack-mounted battery to its ultra-sim range. It has a storage capacity of 5.12 kWh and a nominal voltage of 51.2 V. It measures 670 mm x 475 mm and is 89 mm thick.
Fraunhofer ISE showcases solar thermal facades for heat pumps
Fraunhofer ISE has developed solar thermal facade panels that function as heat pump sources in buildings. The solution is made of ultra-high-performance concrete for aesthetic architectural facades.
New nickel-manganese-cobalt battery for maritime applications
EST-Floattech has developed a nickel-manganese-cobalt (NMC) energy storage system for maritime applications. The are two versions of the battery modules, with storage capacities of 5.8 kWh or 10 kWh. The company also plans to offer a variant with lithium iron phosphate (LFP) battery chemistry.
The Hydrogen Stream: LCOH of subsidized green hydrogen under $2/kg
Lazard explains in a new report that the levelized cost of hydrogen (LCOH) is normally lower for green hydrogen than for pink hydrogen, using both PEM and alkaline electrolyzers, with or without subsidies. Meanwhile, Australian authorities are trying to increase the competitiveness of the local hydrogen sector, while car companies are updating their fuel cell plans.
Saltwater flow battery produces graphene while charging
Salgenx has developed a way to produce graphene on demand from its saltwater flow battery. The tech exploits the electrochemical properties of the battery’s cathode to exfoliate graphite into individual layers of graphene. The company says it can produce graphene for less than $1.25 per gram, providing storage businesses with an additional revenue stream.
Only5mins! – Lower electrolyzer costs crucial for green hydrogen deployment
Low electrolyzer costs, low capex, a low levelized cost of energy, and a decent capacity factor are key to developing viable green hydrogen projects. George Touloupas, senior director of technology for Clean Energy Associates, tells pv magazine about the main challenges and the current price trajectory for green hydrogen tech.
Tesla Master Plan projects 3 TW of solar and 6.5 TWh of storage in US
Tesla releases its third Master Plan, with a broad focus on clean electricity generation and storage, as well as related manufacturing costs.
Generac unveils commercial, industrial battery storage system
Generac says its new zero-emissions SBE line of stationary storage systems will be available in capacities ranging from 200 kWh to 1,000 kWh.
