Building on research work at Sweden’s Chalmers University of Technology, Sinonus has developed carbon fiber-based structural batteries that not only store energy but also become an integral part of a product’s structure. Their possible span of energy density is said to be around 25-50% of a conventional lithium-ion battery at current technology level.

The Clean Air Task Force (CATF) says in a new report that dedicated clean hydrogen production and use is often a costly, inefficient decarbonization strategy for the power sector, while American Airlines says it has signed a deal with ZeroAvia for 100 hydrogen-electric engines.

The “largest European thin-film solar cell manufacturing plant” will begin operation after receiving production certification. Midsummer executive Erik Olsson tells pv magazine Italy that production is expected to start after the summer, at a time of sharp increase in demand for thin-film photovoltaic cells from the commercial and industrial solar segment.

An international research group has sought to build for the first time a perovskite solar cell with the help of ChatGPT. The experiment helped the scientists identify a series of materials for the cell composition and the results were cells with a higher power conversion efficiency compared to that of reference cells built without the material proposed by the large language model.

Sticky Solar Power is taking orders for industrial-scale versions of its novel room-temperature cell interconnection system, which is reportedly well-suited for back-contact (xBC), perovskite, and heterojunction cell technologies.

At a time of growing demand for battery energy storage, pv magazine spoke with Eloisa de Castro, CEO of Enerpoly, a Swedish company preparing to launch the world’s first zinc-ion battery megafactory on its home turf. Having solved rechargeability issues, the company expects its safe and sustainable zinc-ion batteries, which rely solely on a European supply chain, to increase their market share in the years to come.

Solutions for Our Climate (SFOC) says in a new report that blue hydrogen might not be an effective climate solution, while TotalEnergies and its partners have agreed to explore green hydrogen potential in Tunisia.

Brion Solenergi has started working on the Nordic region’s biggest rooftop solar project. The 14 MW array will span the rooftop of a warehouse owned by Danish transport company DSV.

Nikola plans to sell 100 hydrogen fuel-cell trucks for logistic operations in California, Volvo has started developing hydrogen combustion trucks, and Airbus has announced plans to launch a study into hydrogen projects in the US state of Georgia.

New research from Sweden suggests that low platinum fuel cells for hydrogen vehicles, when scaled up for the same number of cells, may achieve similar or higher efficiencies compared to commercial fuel cells. Their modeling is expected to act as a bridge between material science research and vehicle implementation.
