The world would have been a different place today had John Goodenough accepted the Shah of Iran’s $7 million offer, in 1974, to carry out solar research. Instead, he secured a job as the head of inorganic chemistry at the University of Oxford. During his tenure, he made a lithium-ion battery discovery that would affect the lives of almost everyone.

The German authorities have announced plans to double domestic electrolysis capacity to 10 GW by 2030, BloombergNEF has reported that green hydrogen became competitive with gray hydrogen earlier than expected, and Chinese researchers have presented new research on microbial hydrogen production.

Scientists at the Max Planck Institute for Solid State Research have developed a bifunctional solar battery device that enables simultaneous light charging, charge storing, and electric discharging. The device relies on a bifunctional carbon nitride photoanode to harvest sunlight and store its energy via trapped electrons.

German company RENA Technologies has announced the first sales of a new tool for silicon cell manufacturing. The tool is used for etching/removal of unwanted material on one side of a solar cell, and will be integrated into the gigawatt-scale production of an unnamed manufacturer in South Asia working with TOPCon technology.

Compared to the Inflation Reduction Act (IRA) signed by Joe Biden’s administration in the US, the EU’s approach to establishing solar manufacturing appears slow and lacking in clarity. In this blog post, I will explore the EU’s renewable energy policy, specifically its emphasis on solar manufacturing, and evaluate whether Brussels is doing enough to establish a European solar supply chain.

Teknisolar will develop a pilot lamination line for innovative photovoltaic technology based on tandem solar cells.

Clever-PV has developed a manufacturer-independent energy management solution for homes. The app is free to download from app stores and can be connected to PV systems, wall boxes, heat pumps, and other smart devices. This allows users to optimize the use of self-generated solar power.

Dutch gas supplier Gasunie says several market participants have reserved capacity in the first salt cavern for large-scale hydrogen storage near the Dutch city of Groningen. According to current planning, the first cavern will be operational by 2028.

US researchers have developed new integrated halide perovskite photoelectrochemical cells, while Fortescue Future Industries has revealed plans to acquire a hydrogen project from Nikola in Arizona.

Germany’s Fraunhofer Institute for Applied Solid State Physics (IAF) has developed an ultra-efficient circuit topology for voltage converters with an electrical efficiency of 99.74%. The tech could considerably raise the coefficient of performance for electrocaloric heat pumps and the scientists are now considering components based on semiconductor gallium nitride (GaN) for higher power density and efficiency.
