New EV battery offers 50% more density than traditional lithium-ion batteries
Ionblox says it will use $32 million of series B funding to support the buildout of a novel silicon anode electric vehicle battery.
IIT-Madras Research Park signs thin-film R&D MoU with First Solar
IIT Madras Research Park and US-based First Solar will cooperate on a range of research and development (R&D) activities including the localization of thin film and other next-generation PV technology supply chains in India, high-volume manufacturing, PV module testing, and high-value recycling.
Survey shows 34.3% failure rate for residential inverters over 15 years
The Bern University of Applied Sciences in Switzerland has published the initial results of a survey on the durability and performance of residential PV inverters and power optimizers over a 15-year period. They found that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operation.
Sodium aluminum battery for renewables storage
US researchers have designed a molten salt that could potentially reach an energy density of up to 100 Wh/kg at a cost of $7.02/ kWh. The battery uses an aluminum cathode that charges quickly and reportedly enables longer-duration discharge.
Dutch startup unveils controller to store excess PV power in hot water
Solyx Energy has developed a device to maximize solar self-consumption in residential homes. The sensor measures how much solar power can be fed back into the grid at different times, while a controller redirects that excess energy into an electric water heater.
Prime Minister flags off OIL’s hydrogen bus at India Energy Week
Oil India Ltd (OIL) indigenously developed this hydrogen fuel cell-based bus under its Startup incubation program SNEH. The bus is powered by a 60 kW PEM fuel cell.
AC vs. DC in residential buildings equipped with solar-plus-storage
Scientists in Sweden have compared AC and DC topologies in PV-powered buildings using battery storage. They have found that DC distribution systems can achieve energy savings when they are combined with solar-plus-storage systems.
Enphase demonstrates bidirectional EV charger
Enphase’s new bidirectional EV charger enables vehicle-to-home and vehicle-to-grid applications, and can be integrated with its home energy systems.
Reflective membrane to increase albedo, power yield in bifacial PV projects
Germany-based Solmax has developed a reflective membrane made of polyethylene resins and coated with a thin white polyethylene layer that reflects ultraviolet (UV) rays. The company claims the membrane can increase the energy yield of a bifacial PV project by between 5% and 20%, depending on the plant configuration.
Reliance Industries unveils India’s first hydrogen combustion engine technology for heavy-duty trucks
Reliance Industries Ltd developed the hydrogen internal combustion engine technology solution for heavy-duty trucks together with Ashok Leyland and other technical partners. It plans the technology’s first commercial deployment at scale initially across its captive fleet following extensive test and validation.
