US researchers have investigated how grid-forming inverters could help to resolve network synchronization issues. They have found that multi-loop devices could offer strong damping support in power systems with intermittent renewables.

Germany’s Bosch wants to focus on green hydrogen production in Europe as a new dedicated business area. It said it will draw on its fuel cell expertise to build new productions facilities.

Japan’s Sumitomo Corp. has revealed plans to build a green hydrogen pilot plant at Rio Tinto’s Yarwun alumina refinery in the Australian state of Queensland.

$3.1 billion is available to increase production of American-made batteries, with a separate $60 million to support second-life applications for used EV batteries, along with development of processes for recycling materials back into the battery supply chain.

Singaporean researchers have developed a semitransparent perovskite solar panels for applications such as building-integrated PV, vehicle-integrated solar, and smart glasses. They built it with a highly transparent and conducting transparent conductive oxide layer via tin-doped indium-oxide sputter deposition.

Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.

Portuguese startup Solarud has developed a way to eliminate soiling around the frames of PV panels with low inclination slopes. The device drains water that would otherwise stay stagnant on the surface of modules.

Solarwatt and Stiebel Eltron have agreed to cooperate on the development of heat pumps.

Lithion’s Stack’d Series LFP batteries are modular and can be scaled in 4.8 kWh increments, from 9.6 kWh to 38.4 kWh.

The development of a set of testing protocols for perovskite solar cells intended for use outside Earth’s atmosphere could lead to the devices being installed permanently, and even manufactured, on the moon.
