First AI-based control method for vanadium redox flow batteries
Australian researchers are proposing a novel, learning-based H∞ control method to enhance the performance of vanadium redox flow batteries in DC microgrids.
Micro compressed air storage system for residential, industrial applications
A Polish research team has developed a micro compressed air storage system that could be used in residential and industrial buildings where additional low-temperature waste heat is available. The system is claimed to have optimal control of the compressed air expansion process performance via pulse width modulation (PWM).
Tesla launches Powerwall 3 battery
Tesla has launched the Powerwall 3 battery with an energy capacity of 13.5 kWh and continuous on-grid power of 11.5 kW, featuring dimensions of 110 cm x 61 cm x 19.3 cm and a weight of 130 kg.
PV-driven heat pump system for freshwater production, cooling, hot water
Scientists in India have combined a solar-assisted heat pump with a humidification-dehumidification and vapor compression refrigeration (HDH-VCR) cycle to generate heat and cooling. The system is reportedly able to generate up to 5.5 l per hour (LPH) of fresh water while achieving an ‘enhanced’ coefficient of performance.
How long do residential solar inverters last?
A range of different factors can affect the productive lifespan of residential solar inverters.
Hybrid hydro-PV systems increase producer profits by up to 18-21% in sub-Saharan Africa
A team of researchers from Norway analyzed a case study of a cascade hydropower system hybridized with both floating and ground mounted PV under sub-Saharan African market conditions. It found that hybrid systems can reduce seasonal variability in renewable energy generation and increase annual producer profits under both PPA and spot market schemes.
