US scientists have developed a battery that can retain 92% of its initial capacity over periods of 12 weeks, with a theoretical energy density of 260 W/hour per kg. It was built with an aluminum anode and a nickel cathode, immersed in molten-salt electrolyte.
Germany’s Ostermeier H2ydrogen Solutions has developed an electrolyzer that works with tap water, with bottles to store hydrogen and a fuel cell or a Wankel engine to produce electricity. The system has a capacity ranging from 1kW to 100 kW, which corresponds to hydrogen production of 0.2-20 Nm3/h.
India’s Gautam Solar says its gel batteries provide a safer, cost-effective, and long-lasting alternative for the energy storage space.
Photovoltaics can wipe out 4.25 billion tons of carbon emissions every year this decade, according to the UN Intergovernmental Panel on Climate Change. Even so, the actions announced so far remain way short of what is needed, with capital flows to fossil fuels still greater than the cash directed toward combating climate change.
These self-sustaining universal electric vehicle charging stations are powered by Visaka’s ATUM solar roof.
The integrated EV ride-hailing and charging company will use the amount to purchase 3,000 all-electric cars.
India has 10,76,420 registered electric vehicles, with 1,742 public charging stations operational as of March 21, 2022.
Although we may have just about commenced our run in the electric vehicle (EV) race, it is critical that we jump-start the pace of adoption by enhancing the overall perception of EVs from a safety and longevity standpoint.
German scientists have tried to determine whether a PV system linked to a small electrolyzer, a fuel cell, and lithium-ion batteries could fully power a grid-connected household. Their new proposal consists of a 6.8kW PV array, a 5kW electrolyzer, a 1.24kW fuel cell system, and battery storage.
The US manufacturer has expanded the battery capacity options for its SunVault Storage product, up to 26 kWh and 52 kWh configurations.
