A National Energy Technology Laboratory (NETL) led consortium of national laboratories met recently with an advisory board to discuss the development of alloys that can withstand long-term exposure to hydrogen-containing environments at elevated temperatures.
Much of the discussion at the meeting of the consortium, called eXtremeMAT-H2, focused on addressing materials-related challenges associated with the use of hydrogen as a fuel and its impact on the materials of construction at key industries.
“This meeting of the eXtremeMAT-H2stakeholder advisory board allowed representatives from utilities that produce electricity, gas turbine manufacturers, companies that produce hydrogen gas and other industries to provide their feedback on the quality, relevance and direction of our research,” NETL’s David Alman, associate director, Materials Engineering and Manufacturing, said.
The use of hydrogen as a fuel is integral to achieving net-zero greenhouse gas emissions by 2050 because it offers significant potential to reduce carbon dioxide emissions in sectors that are difficult to decarbonize. These industries include power generation, heavy-duty transportation, chemical production and industrial heating.
“It is well known that hydrogen can make alloys brittle. While lower-temperature hydrogen embrittlement has been studied extensively, there have only been a few studies focused on the impact of hydrogen at elevated temperatures. With more power production and industrial processes expected to switch to hydrogen, it is important to address this gap and understand the impact of hydrogen on the long-term performance of alloys. This meeting enabled industry to hear an update on eXtremeMAT-H2’s progress and for the eXtremeMAT-H2 team to learn the perspectives from a variety of different industries on research needs,” Alman said.
The consortium deploys computational tools to accelerate the development cycle of cost-effective alloys needed to realize durable materials for extreme environments.
“The tools being developed by eXtremeMAT-H2 allow for better predictive capabilities of alloy performance and can reduce the time and cost of designing reliable and safe components for hydrogen systems. The eXtremeMAT-H2 team is developing a better understanding of the connections between the alloy chemistry, microstructure and properties in hydrogen — information that is paramount for making more accurate predictions about alloy service life and designing alloys that are more resistant to failure when exposed to hydrogen-containing environments. Better alloys for components are critical in the transition to using clean hydrogen to produce electricity, chemicals and steel while reducing greenhouse gas emissions,” Alman said.
The advisory board includes engineers and representatives from 16 companies as well as research and professional organizations.
The eXtremeMAT-H2 consortium includes members from the Ames National Laboratory, Los Alamos National Laboratory, Oak Ridge National Laboratory, Sandia National Laboratories, and NETL.
