How do you store renewable energy so it’s there when you need it, even when the sun isn’t shining or the wind isn’t blowing? Giant batteries designed for the electrical grid — called flow batteries, which store electricity in tanks of liquid electrolyte — could be the answer, but so far utilities have yet to find a cost-effective battery that

Two short years ago, Tesla pieced together the world’s largest battery for the state of South Australia, and with great effect. The company is continuing its moves in this space with a massive new battery dubbed the Megapack, of which it says enough units can be linked together to take energy storage into the giga-scale realm. The 129-MWh facility Tesla built for

Metal-air batteries are one of the lightest and most compact types of batteries available, but they can have a major limitation: When not in use, they degrade quickly, as corrosion eats away at their metal electrodes. Now, MIT researchers have found a way to substantially reduce that corrosion, making it possible for such batteries to have much longer shelf lives.

By synthesizing novel material for electrode that facilitates reversing of the chemistry of ions, a group of researchers combat the wasteful aspects of energy sources by laying an important foundation for the production of next-generation rechargeable magnesium secondary batteries.

Scientists have discovered a new material that could hold the key to unlocking the potential of hydrogen powered vehicles. As the world looks towards a gradual move away from fossil fuel powered cars and trucks, greener alternative technologies are being explored, such as electric battery powered vehicles. Another ‘green’ technology with great potential is hydrogen power. However, a major obstacle
