The Status and Impact of DOE’s Energy Materials Network (EMN) on Hydrogen Technology

Hydrogen technology is the focus of this study, with an emphasis on material development to support a clean hydrogen energy economy. TMS has assembled an expert study team to examine the status, impact, and future opportunities of hydrogen technology for the Department of Energy’s Energy Materials Network (EMN) and the EMN’s four hydrogen-related consortia.

The team is leading a 20-month initiative from December 2021 to June 2023. The final report was released in June 2024.

The Status and Impact of DOE’s Energy Materials Network (EMN) on Hydrogen Technology is a TMS science and technology accelerator study that is funded by the Hydrogen and Fuel Cell Technology Office (DOE-EERE-HFTO) via the Pacific Northwest National Laboratory (PNNL).

Planned Milestones

Amplify the four essential technological domains that are crucial for the broad acceptance of clean hydrogen
Review the specific research areas for each of the four EMN consortia related to hydrogen, which are contributing to the progress of the hydrogen economy
Conduct a comprehensive analysis to pinpoint the main gaps, barriers, requirements, and facilitators for the development of materials needed for achieving a competitive and robust clean hydrogen infrastructure
Offer tangible suggestions, significant milestones, thorough action plans, and routes for implementation that are necessary to lay the groundwork for the transition from basic concepts into manufactured components in the field of clean energy

Keller's technical work has been at the leading edge of research and development (R&D) in hydrogen technology, hydrogen infrastructure, and hydrogen codes and standards. He has academic and R&D expertise in combustion, heat transfer, thermodynamics, mass transfer, fluid dynamics, gas dynamics, and materials science. His applied science leadership stems from managing a hydrogen program overseeing long-term, multi-million-dollar R&D projects with numerous partners and stakeholders. As an entrepreneur he has founded technical consultancies providing guidance and project oversight to governments, international organizations, and private interests.

For nearly three decades, Keller was involved in combustion and hydrogen R&D at Sandia National Laboratories (SNL), where he built and administered a globally recognized hydrogen program. Projects he directed included: hydrogen fueled conventional technologies (internal combustion and turbine), fuel cell development for transportation, hydrogen storage, hydrogen effects on materials, thermochemical solar and nuclear hydrogen production, and the science and engineering behind international codes and standards for hydrogen deployment. Following SNL, he founded a technical consulting firm in California with the primary focus on hydrogen codes and standards development for the U.S. Department of Energy (DOE). In this capacity, he provides leadership and represents the DOE in national and international bodies such as ISO TC 197, H2USA, FCHEA, HySafe, and IPHE. His combination of technical, management, and international regulatory expertise uniquely qualifies him to develop technical teams, support hydrogen infrastructure deployment oversight, and manage globally scalable hydrogen initiatives.

Keller is the recipient of numerous distinctions and technical awards and has over 175 publications, including four patents. Keller studied industrial engineering at New Mexico State University, received a B.S. in mechanical engineering at the University of California, Santa Barbara, and an M.S. and Ph.D. in mechanical engineering at the University of California, Berkeley.
