First Solar has agreed to pay $38 million to buy Swedish manufacturing startup Evolar AB, as it seeks to expand development of high-efficiency tandem PV tech.

Sono Motors, a solar electric-vehicle manufacturer in Germany, has terminated its Sion passenger car development program, as it has failed to secure enough funding to support pre-series production. It says it will now focus exclusively on retrofitting and integrating its patented solar technology into third-party vehicles.

A scalable thermal energy storage prototype system that combines the best latent and sensible heat transfers is now market-ready after three years of testing. It consists of engineered cementitious materials and thermosiphons in a combination that enables fast, efficient thermal performance at low cost.

Low participation rates for vehicle-to-grid (V2G) tech of just 12% to 43% are needed to provide short-term grid storage demand throughout the world by as early as 2030, according to a group of Dutch and U.S. researchers.

NOMAD Transportable Power Systems (NOMAD) has started offering plug-and-play, utility-scale mobile energy storage systems. There are three versions – 2 MWh, 1.3 MWh, and 660 kWh – with a patent-pending docking platform.

The New York City authorities have determined that a lithium battery in an unspecified micromobility device triggered a recent high-rise fire that injured dozens in Manhattan.

Researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

PG&E has secured approval to set up a vehicle-to-grid (V2G) export compensation mechanism for commercial EV charging customers in California. Sono Motors is debuting its Sion solar electric vehicles in the US market, while Toyota and Jera are installing innovative second-life battery systems in Japan.

Mango Power has developed a 3.5 kWh battery system that can be expanded up to 14 kWh. The product features LFP battery cells from CATL and can be charged through AC wall outlets, with solar panels, or via electric-vehicle chargers.

While still using conventional lithium-ion raw materials, 24M’s technology is said to reduce the number of steps required to manufacture battery cells and thereby the cost by up to 40%. The US company’s SemiSolid design is also said to deliver improved energy density, safety and recyclability.
