New technology to extract hydrogen gas from liquid carriers – pv magazine USA

North Carolina State University (NCSU) has developed an energy-efficient strategy for releasing hydrogen at room temperature from liquid hydrogen carriers, which uses less rhodium. Elsewhere in the world, Airbus has launched its zero emissions development center in the UK, Toshiba ESS has partnered with Fusion Fuel to target the Australian and European markets, and Corfo has signed agreements to fund three renewable hydrogen projects with LNG Quintero, iCAP and Air Liquide in Chile.

North Carolina State University (NCSU) has developed a continuous flow reactor applying a reusable photocatalyst and sunlight to extract hydrogen gas from its liquid organic carrier (LOHC) using less rhodium (Rh). Researchers achieved 99% efficiency in three hours, eight times faster than conventional batch reactors. The room temperature reactor looks like a thin, transparent tube filled with micron-scale titanium oxide (TiO2) grains. Hydrogen-carrying liquid is pumped out one end of the tube. Only the outer grains of titanium oxide, those exposed to the sun at the other end of the tube, are covered with rhodium. These photoreactive catalysts react with the liquid carrier to release hydrogen molecules in the form of gas. “In a conventional batch reactor, 99% of the photocatalyst is titanium oxide and 1% is rhodium. In our continuous flow reactor, we only need to use 0.025% rhodium, which makes a big difference in the final cost. A single gram of rhodium costs more than $500,” said Milad Abolhasani, corresponding author of the recently published article in ChemSusChem. According to the researchers, the system should be easy to scale or scale to allow catalyst reuse on a commercial scale. “You can simply lengthen the tube or merge several tubes in parallel.” The flow system can operate continuously for up to 72 hours before losing efficiency. The catalyst can be “regenerated” without removing it from the reactor in about six hours. The system can then be restarted and run at full efficiency.

Airbus launched its Zero Emissions Development Center (ZEDC) in Bristol, UK to develop, test and manufacture cryogenic fuel systems. The center will work on all product capabilities, from components to complete system and cryogenic testing. The new ZEDC joins other centers focused on cryogenic liquid hydrogen tanks in Spain, Germany and France. “All Airbus ZEDCs are expected to be fully operational and ready for ground testing with the first fully functional cryogenic hydrogen tank in 2023, with flight testing beginning in 2026,” the European aerospace company wrote.

Toshiba Energy Systems and Solutions has entered into an agreement with the Irish company Fusion Fuel to study collaboration opportunities, aimed at developing sales of electrolysers in Europe and Australia. Fusion Fuel will evaluate the use of Toshiba’s ESS Membrane Electrode Assemblies (MEA) in its proprietary Proton Exchange Membrane (PEM) electrolysers; and Toshiba ESS will explore the use of its local sales channels to expand sales of Fusion Fuel’s PEM electrolysers in Australia. “In addition, the two companies will also explore potential collaboration for future sales of Toshiba ESS solid oxide electrolysis cells, which Toshiba ESS aims to bring to market in 2025,” Toshiba ESS wrote.

Chile Development Agency corfo signed agreements with the LNG regasification plant Quintero, the iron producer CAP and the industrial gases supplier Air Liquide to finance the development of the first green hydrogen production plants on an industrial scale in Chile. The 10 MW LNG Quintero project aims to develop, build and operate a green hydrogen plant in the Valparaíso region. CAP’s 12 MW project focuses on the Biobío region, while the Antofagasta region will host Air Liquide’s 80 MW project. The three companies received respectively 5.7 million dollars (5.3 million euros), 3.6 million dollars and 11.7 million dollars. “These three initiatives are among the six selected by Corfo last December, which, when installed, will have a total electrolysis capacity of 388 MW, equivalent in size to what is currently in service around the world. They are expected to generate investments of 1,000 million dollars and produce more than 45,000 tons of hydrogen per year,” Corfo wrote.

The german parliament passed the bill tabled by the government to bypass specific procedural steps, such as the need for an environmental impact assessment, to install two floating terminals in Wilhelmshaven and Brunsbüttel by next winter. LNG facilities should be “hydrogen ready”.

based in the United States Aerial productsOman’s energy group OQ and Riyadh-based developer ACWA Power signed a co-development agreement towards a multi-billion dollar investment in a global scale hydrogen-based green ammonia production facility powered by renewable energy in Oman.

Liquid air invested $250 million to open its largest liquid hydrogen production and logistics infrastructure facility in North Las Vegas, Nevada. The facility will produce 30 tons of liquid hydrogen per day, primarily for California’s mobility sector, the Paris-based industrial gases company wrote.

French producer of green hydrogen Lhyfe and Swedish local energy company Trelleborgs Energi have joined forces for a pre-study for a local renewable hydrogen production system in the far south of Sweden. The results are expected to be presented in the summer of 2022. Earlier this weekLhyfe has entered into an industrial agreement with the Spanish EDP Renewables to identify, develop, build and manage renewable hydrogen projects.

Algeria Sonatrach and that of Italy Eni signed a memorandum of understanding (MoU) to accelerate the development of gas fields in Algeria and decarbonization via green hydrogen.
