PV-based molecular thermal energy storage system achieves 14.9% solar utilization efficiency
An international research term investigated the feasibility of converting solar energy into chemical energy with the design of a hybrid device featuring a solar energy storage and cooling layer integrated with a silicon-based solar cell. Under testing, the device recorded a record energy storage efficiency and decreased the cell’s surface temperature by approximately 8 C under standard solar irradiation conditions.
Offgrid hybrid PV-biogas system for residential applications
The system was conceived to respond to Lebanon’s energy crisis and help homeowners become independent from grid electricity. Biogas production is used when PV power generation is insufficient and machine learning techniques help the system predict solar energy production.
China to host 1.6 GW vanadium flow battery manufacturing complex
The all-vanadium liquid flow industrial park project is taking shape in the Baotou city in the Inner Mongolia autonomous region of China, backed by a CNY 11.5 billion ($1.63 billion) investment. Meanwhile, China’s largest vanadium flow electrolyte base is planned in the city of Panzhihua, in the Sichuan province.
Trina plans 2,640 MWh big battery for Western Australia
China’s Trina Solar has submitted plans to build 660 MW/2,640 battery storage facility at Kemerton in an industrial zone south of Perth, Western Australia.
Livoltek launches 120 kW EV chargers
China’s Livoltek says it has developed 120 kW electric-vehicle chargers with 140 kW input and a 100 kWh LFP battery, supporting the CHAdeMO, GB/T, CCS1, and CCS2 standards.
Switzerland to host world’s largest redox flow storage project
Flexbase plans to build a 500 MW redox flow storage project in Laufenburg in early 2025.
Dual-source CO2 heat pump based on photovoltaic-thermal evaporators
Researchers in Italy have conceived a dual-source heat pump system that uses both a finned-coil evaporator and a solar evaporator made with three photovoltaic-thermal panels. Thanks to the combined action of the two evaporators, the heat pump can achieve higher evaporation pressure and coeffficient of performance.
Greece announces downsized auction for battery storage in coal regions
The Greek government decided to auction 100 MW less capacity than initially sought and to offer more money to the awarded projects than expected.
Firebrick thermal energy storage could reach 170 GW in the U.S. by 2050
Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a study out of Stanford University.
The Hydrogen Stream: Equatic making anodes to produce H2 from seawater
Equatic says it has started annual production of 4,000 anodes for hydrogen generation from seawater in Singapore and Canada, while Nuvera Fuel Cells says it will demonstrate its first operational hydrogen-powered AC generator set and DC fast charger.
