Tokyo technology Scientists have reported that their newly developed perovskite – BaScO2.5 doped with W6+ cations (BaSc0.8W0.2O2.8) – has achieved high proton conductivity at low and intermediate temperatures due to the large amounts of oxygen vacancies. “The donor doping of large W6+ allows this material to absorb more water to increase the proton concentrationlike reduce proton capture by electrostatic repulsion between the dopant and the proton,” said the scientists who published “High proton conduction due to complete hydration in perovskite with a high oxygen deficiency” in the Journal of Materials Chemistry A. “These findings could pave the way for the rational design of new perovskites for protonic ceramic fuel cells (PCFCs) and electrolytic cells (PCECs).”
RWE said it plans to build an 800 MW hydrogen-ready gas-fired power plant at its Gersteinwerk power plant in Germany. “After intensive technical research, RWE commissioned an Italian-Spanish consortium to plan the project,” said the German company. “The approval process for the plan is already underway.” She noted that the consortium consists of Ansaldo Energia (Italy) and Tecnicas Reunidas (Spain). Nikolaus Valerius, CEO of RWE Generation, said the company will only make a final investment decision after it has secured connection to a hydrogen network.
The German Federal Cabinet has approved a draft law to significantly accelerate the introduction of hydrogen to the market until 2030. “The Hydrogen Acceleration Act further simplifies planning, approval and award procedures for the production, storage and import of hydrogen: for example maximum deadlines take place for approvals under water law, the early initiation of measures is simplified, procedures have been shortenedexpedited procedures are accelerated and test procedures for electrolyzers are simplified,” said the German government. It argued that hydrogen infrastructure projects would serve the overriding public interest. “This means they are of particular importance when approving authorities weigh decisions.”
