Using surplus solar power to pre-cool, pre-heat homes
Scientists in Australia have shown how pre-cooling and pre-heating could be implemented in Australian buildings with the support of excess solar power. Their analysis has demonstrated that summer has the highest potential for air conditioning demand reduction.
Japanese energy supplier to use green hydrogen for district heating, power
Akasaka Heating & Cooling Supply says it will use green hydrogen produced at an unspecified location in Japan to produce heat and electricity for its Akasaka 5-chome district heating system in central Tokyo.
Austa releases all-in-one storage system for residential use
Austa has launched an all-in-one residential storage system with a three-phase inverter offering output from 5,000 W to 15,000 W and storage capacities ranging from 10 kWh to 30 kWh.
Mibet launches new floaters for PV systems on deep water
Mibet has released new floaters for PV systems deployed in deep water. The G4M system, already installed in Indonesia on a body of water with a depth of 60 meters, allows the solar panels to be tilted at 5 degrees to 15 degrees.
Chinese scientists build polysulfide-iodide redox flow battery with 87.9% energy efficiency
Scientists in China designed a suplhuer-based redox flow battery with a peak power density of 95.7 mW cm2 and an average energy efficiency of 76.5% at 30 mA cm2 within 50 cycles.
Solar-plus-storage for extreme low temperatures
Scientists in the United States have created a testing platform for energy harvesting in solar-plus-storage systems under extreme temperatures ranging from -180 C to 300 C.
Heat pump control strategy for energy communities
Researchers have utilized measured data from a small energy community on a Finnish university campus to simulate its operation under various control strategies. The first control strategy prioritizes the use of heat pumps, while the second prioritizes price. Total costs were reduced by up to 25% with the second option.
Offshore vs. ground-mounted PV
Researchers in Saudi Arabia have compared the performance of ground-mounted PV plants with that of off-shore solar facilities and have found that floating installations benefit from the cooling effect of the seawater.
Zendure launches new residential batteries
The US-based company unveiled a battery designed for balcony applications and a storage system for rooftop PV systems. Both products are AI-powered.
CRRC releases 5 MWh liquid-cooled energy storage system
The world’s largest rolling stock manufacturer says that its new container storage system uses LFP cells with a 3.2 V/314 Ah capacity. The system also features a DC voltage range of 1,081.6 V to 1,497.6 V.
