New dehydrogenation process to improve hydrogen storage – pv magazine USA

A look at three different hydrogen projects around the world, including one at the U.S. Department of Energy’s Ames Lab, which has pioneered a new nitrogen-carbon catalyst to extract hydrogen from storage materials of hydrogen at mild temperatures and under normal atmospheric conditions.

The U.S. Department of Energy’s Ames Laboratory has released a new nitrogen-carbon catalyst for extracting hydrogen from hydrogen storage materials at mild temperatures and normal atmospheric conditions without the use of metals or of additives. This “breakthrough” would alleviate current problems with chemical storage and in particular dehydrogenation, said the team led by scientists Long Qi and Wenyu Huan. “The key to its effectiveness is the nitrogen structure. Catalytic activity can take place at room temperature due to the closely spaced unique graphitic nitrogens as nitrogen assemblage that formed during the carbonization process. Nitrogen assembly catalyzes the cleavage of carbon-hydrogen (C‒H) bonds in LOHCs and facilitates the desorption of hydrogen molecules,” Ames Lab wrote Thursday. The related article was published on January 28 on Scientists progress.

A team of engineers from the University of Delaware demonstrated a way to capture 99% of carbon dioxide from the air using a hydrogen-powered electrochemical system. “We demonstrate an electrochemically controlled CO2 separator (EDCS) to remove CO2 from the air supply using a shorted membrane that conducts both anions and electrons. This EDCS is powered by hydrogen like a fuel cell but does not need electric wires, bipolar plates or current collectors, and can therefore be modularized like a typical separation membrane,” the six researchers wrote. in the article published last week in natural energy. The University of Delaware wrote that as the hydrogen economy grows, this electrochemical device could also be used in airplanes and buildings. The approach tested by the team led by Professor UD Yushan Yan is to short-circuit the device internally. “It’s risky, but we managed to control this short-circuit fuel cell by hydrogen,” comments Lin Shi, doctoral student of the Yan group and lead author of the article.

South African President Cyril Ramaphosa said the country was working to attract new investment in electric vehicles and hydrogen, adding that priority should be given to green hydrogen given “the unique opportunity ” from the country. Germany is seen as a potentially central trading partner. “Over the past year, [the] The government has built on its successful Hydrogen SA strategy to make major strides in positioning South Africa as a global leader in this new market. This includes the development of a hydrogen society roadmap for the next 10 years as well as a green hydrogen strategy for the Northern Cape, supporting the development of a green hydrogen pipeline from worth about R270 billion. [€15.65 billion]Ramaphosa said Thursday in his 2022 State of the Nation Address. Earlier this week, the South African President appointed Daniel Mminele to lead the new Presidential Team on Climate Finance. “His experience before the SARB [South African Reserve Bank] included credit risk analysis, corporate banking and project finance and structured at private banking institutions in Germany, the UK and South Africa,” the government wrote on Wednesday.

The Norwegian consulting and classification company DNV has launched, together with 18 industrial partners, a new Joint Industrial Project (JIP) to improve the standardization of hydrogen production systems using renewable energy electrolysis to produce green hydrogen . “We are meeting this challenge by joining forces with major industry partners to work towards a new certification system and industry best practices for electrolysers that will make it easier for water electrolysis projects to be successful. We undertook a similar approach for the wind energy industry about 30 years ago, which has proven to be very successful,” commented Axel Dombrowski, Director of Innovation and Digitization for Energy Certification. at DNV. Partners include BP, EDP, Equinor, Industrie De Nora, ITM Linde Electrolysis, McPhy, Shell, Siemens Gamesa and thyssenkrupp nucera. The JIP is open to other partners until mid-April 2022.

Norway’s Aker Clean Hydrogen increased its portfolio of projects and prospects currently under development to 2 GW, according to its fourth quarter 2021 results. Aker Clean Hydrogen was launched in February 2021. Among its key projects in the last quarter were the completion of the feasibility phase of the Hegra green ammonia project, the extended network authorization process for the Berlevåg green ammonia project and certain developments of the Aukra project. “Aukra’s hydrogen hub is technically and commercially viable; initial estimates showing a competitive discounted cost of hydrogen,” Aker Clean Hydrogen wrote on Friday.

Energy consultancy Wood Mackenzie expects more technology solutions related to storage and chemical plant design this year, citing the case of Haldor Topsoe, which redesigned its ammonia plant to respond to fluctuations in hydrogen supply. On the other hand, fewer hydrogen projects should be announced in the coming months. “Will we see the same growth rate for CCUS and hydrogen pipelines in 2022? We think not. The coming year will be dedicated to maturing projects and securing funding,” the consultancy wrote on January 31. Wood Mackenzie said translating hydrogen policies into reality will be politically sensitive. On Thursday, for example, the AP news agency reported that a panel of state lawmakers rejected a bill that would have provided new financial incentives in New Mexico for hydrogen derived from natural gas.

Boston-based clean energy solutions company Angstrom Advanced wrote that the development of the hydrogen energy industry also depends on creating “hydrogen communities.” The idea is to create an integrated energy system based on hydrogen. “At present, a few relevant projects have been started around the world, including but not limited to Rugao Hydrogen Town, Jiangsu, China; Harumi Hydrogen Town, Tokyo, Japan; and Orkney Hydrogen Town, Scotland,” Angstrom Advanced wrote this week.
