New technology for solar water separation – pv magazine International
Helmholtz-Zentrum Berlin (HZB) Solar Fuels Institute has developed a method consisting of pulsed laser deposition, coupled with flash heating and high power lamps, to increase the quality of metal oxide thin films for solar water separation. The usual heat treatment process would be problematic. “Reducing the concentration of atomic defects and improving the crystal order of thin metal oxide films would require heat treatment temperatures between 850 C and 1000 C – but the glass substrate already melts at 550 C .” says HZB. He said flash-heating the thin film of metal oxide through high-powered lamps could solve the problem. “This heats it up to 850C without melting the underlying glass substrate,” HZB’s solar fuels unit said Monday. Heating by rapid heat treatment (RTP) improved crystallinity, electronic properties and performance, “leading to a new record performance of 1 mA/cm2 for this material, 25% better than the previous record,” it said. he declares.
the Fraunhofer Institute for Telecommunications and the Fraunhofer Heinrich-Hertz-Institut (HHI) in Germany are working on fiber optic based hydrogen sensors with a special functional coating around the glass fiber sensor. As the hydrogen industry grows, so does the emphasis on safety. Günter Flachenecker, senior scientist at Fraunhofer HHI, said commercially available hydrogen safety sensors — typically catalytic heat tone sensors or electrochemical cells that require electrical power — are dangerous. “Both variants could act as an ignition source and trigger the explosion they are meant to prevent, if either the device or the power supply lines fail,” Flachenecker said. He added that their fixative optical sensors don’t pose this risk because they don’t require complex wiring. “We work with catalytic layers, for example palladium or palladium alloys. Palladium has the ability to absorb hydrogen, much like a sponge. As soon as the two substances meet, the hydrogen disintegrates into its atomic fragments and the released hydrogen atoms enter the palladium crystal framework. This causes an elongation in the optical fiber, which can be measured instantly,” Flachenecker said. According to a press release from Fraunhofer HHI last week, optical fibers are predestined for sensory applications in a security-related environment, “because they are robust and have only a small diameter of about a quarter millimeter”.
NTU Singapore develops new technologies to extract hydrogen from liquid organic hydrogen carriers. It is supported by the National University of Singapore (NUS). Japanese companies Chiyoda Corp. and Mitsubishi Corp., Singapore-based PSA Corp. and Sembcorp Industries are also collaborating on the project, according to NTU Singapore.
the European Energy Exchange (EEX) started work on a hydrogen index based on price assessments by market participants, in order to establish reliable marketplaces for hydrogen. EEX also said it is participating in the German government-backed H2Global foundation, joining Siemens Energy Global, Thyssenkrupp, Deutsche Bank, Salzgitter and Uniper. “In the interest of the Federal Government, the German economy and, last but not least, society, we see it as our urgent duty to establish a strong and internationally diverse supply chain for hydrogen green. Exchange trading is absolutely part of that as an allocation and coordination mechanism,” said H2Global CEO Markus Exenberger.
Indian oil, Larsen & Toubro (L&T) and ReNew have signed a binding term sheet to potentially form a joint venture to develop the green hydrogen sector in India. The three companies would each hold equal shares in the proposed ventures. “Indian Oil and L&T have signed a binding term sheet to form an equity investment (company) to manufacture and sell electrolyzers used in the production of green hydrogen,” said New Delhi-based Indian Oil. Draft guidelines for India’s National Green Hydrogen Energy Mission indicate that around 40% of the hydrogen produced in the country (around 5 MMT) will be green by 2030.
Green Energy Oman (GEO), an Oman-focused consortium, has awarded a contract to Australian engineering firm Worley to support its 25 GW low-carbon fuels project. “Worley provides conceptual feasibility study services to develop and challenge the green hydrogen energy project defined by GEO. The project includes the optimization of approximately 25 GW of wind and solar generation, the transformation of this renewable energy by electrolysis into green hydrogen, as well as the production, storage and export of green ammonia,” Worley said on Tuesday. . The consortium includes integrated energy company OQ of the Sultanate of Oman, InterContinental Energy and EnerTech, a clean energy investor and developer backed by the Kuwaiti government. Worley said the project aims to produce more than 1.8 million tonnes of low-carbon green hydrogen.
Aragon Hydrogen Valley, Catalonia Hydrogen Valley, Basque Hydrogen Corridor and Navarra Hydrogen Green Agenda agreed on Monday to jointly create the Ebro Hydrogen Corridor, a project that will strengthen inter-territorial coordination between regional initiatives in northeastern Spain. The project is supported by regional entities and the government of Madrid. The Ebro Hydrogen Corridor will target the installation of 1.5 GW of renewable hydrogen generation capacity, as well as the annual production of 250,000 tonnes of renewable hydrogen products by 2030. Repsol CEO Josu Jon Imaz, opened the launch event.
The European Investment Bank (EIB), the Instituto de Crédito Oficial (ICO) and Iberdrola have agreed to produce green hydrogen for industrial use. “To this end, Iberdrola will receive 53 million euros from the EIB and 35 million euros from ICO,” the EIB announced on Monday.
Uruguayan Ministry of Industry, Energy and Mines (MIEM), the Technological Laboratory of Uruguay and the National Agency for Research and Innovation have launched the Sectoral Fund for Green Hydrogen, which aims to finance research, innovation and training projects. National legal entities, private sector groups and proven companies with electrolysers of at least 1 MW can potentially benefit from the fund.
Suncor announced its intention to divest its wind and solar assets while focusing more on hydrogen and renewable fuels. The Calgary-based energy company also announced plans to partner with ATCO on a plan to build a global hydrogen project in the Canadian province of Alberta and deploy renewable fuel technologies. . “In doing so, we are using our strengths, our competitive advantages and our resources,” Suncor CEO Mark Little said Monday.
ZeroAvia station and ZEV signed an agreement to develop green hydrogen fueling infrastructure for California airports. Several publications have also reported that Hyundai may step up plans for hydrogen fuel cell aircraft, with a focus on longer-range eSTOL aircraft.
Hyundai Motor Group, Saudi Arabian Oil Company (Aramco) and King Abdullah University of Science and Technology (KAUST) agreed to jointly develop an advanced fuel for an ultra-lean spark-ignition engine, with the goal of reducing overall vehicle carbon dioxide emissions. “BEVs and FCEVs will be Hyundai Motor Group’s ultimate technologies to achieve carbon-neutral mobility,” Alain Raposo, executive vice president of Hyundai Motor Group, said last week.
Nel Hydrogen – which will open its new hydrogen plant in Herøya, Norway on April 20 – has received two new orders. Biproraf has ordered a hydrogen refueling station for fuel cell vehicles and forklifts in Poland. And Hydrogen Technology and Energy Corp. has ordered a hydrogen refueling module for zero-emission light-duty vehicles in the Canadian province of British Columbia. This latest order is in line with British Columbia’s efforts to open an office to expand hydrogen deployment, with the goal of streamlining projects from proposal to construction. “The BC Hydrogen Office will work with federal and local governments to help attract investment and streamline multi-jurisdictional review and approval processes,” the provincial government said last week.
