Japanese researchers have developed a green rust -based catalyst for sodium borohydride, while South Korean scientists have created a framework to assess liquid hydrogen storage tanks for unmanned aircraft (UAV).
Japanese researchers Have a cheap catalyst created from “green rust” that releases hydrogen efficiently from sodium borohydride. “We report that a mixed Valent [FeII–FeIII] Iron hydroxide, which we call green rust (gr), treated with a CUCL2 solution, shows a good solesis-light-assisted catalytic activity in the direction of SBH hydrolysis in room temperature that is higher than that of existing catalysts, including pt-nanoparties-modified titanxide, “” The researchers wrote in “”Catalyst for sodium borohydride dehydrogenation based on a iron hydroxide platform with mixed-valent“Published in ACS -Catalysis. The team said that even without solar light, the GR-based catalyst shows the turnover frequency of a maximum of 5,000-1 for SBH hydrolysis at higher temperatures, “which is comparable to or one or two orders of size higher than that of existing catalysts based on precious and noble metals under comparable or identical circumstances.”
Yera has started with demonstration tests of hydrogen production in its Shin-Nagoya thermal power plant with DESO. The companies use fixed oxide electrolysis cell (SOEC) systems developed by DESO, with 200 KW electrolysis capacity. “The two companies have now started with the first demonstration tests of Japan at a thermal power plant,” they said. Jera and Denso are planning to scale the electrolysis capacity from 200 kW to a few thousand kW.
South Korean researchers have developed an integrated analytical framework to evaluate the performance and structural integrity of liquid hydrogen storage tanks in unmanned aircraft (UAVs). Team leader Nak-Kyun Cho said the framework is the first holistic system that integrates thermal, structural, fatigue and impact analyzes, designed for UAV operations. Thermal analysis showed that vapor-cooled shield implementation reduction percentages with 15% to 30%. Structural analysis identified pipes and supporters as weaknesses under UAV-specific conditions. Fatigue analysis showed that the ship exceeded the requirement of 10,000 Cycle from ISO 21029-1 standards, achieving an effectively unlimited life of fatigue. The findings were detailed in “Analytical framework for liquid hydrogen storage tanks in UAVs: validation of thermal performance and assessment of structural integrityPublished in the International Journal of Hydrogen Energy.
The European Hydrogen Bank Said that seven of the 15 projects that have been selected for subsidies were withdrawn in his second auction round. The projects represent 1.88 GW new electrolyzing capacity, awarded the majority of the 2.3 GW in May, when € 992 million ($ 1.16 billion) of the available € 1.2 billion was allocated. The withdrawn projects include four in Spain, two in Germany and one in the Netherlands, with fixed premium bid prices between € 0.20/kg and € 0.60/kg.
The H2Med Alliance has welcomed 40 new members in the hydrogen value chain, so that the total membership is brought to 49. Founded in December 2024 by five promoters in Portugal, Spain, France and Germany, the Alliance wants to develop a hydrogen corridor from Portugal to Germany. “In the coming months, the H2Med Alliance will perform its efforts and continue to serve as an essential platform to grow synergies, launch working groups and promote strategic business relationships,” said it.
