The GREET "Train the Trainer" Fellowship with the Hydrogen and Fuel Cell Technologies Office (U.S. Department of Energy – Energy Efficiency and Renewable Energy) is now accepting applications. Contribute to clean energy research and emerging hydrogen technology.

The Hydrogen and Fuel Cell Technologies Office (HFTO) is seeking talented and innovative individuals to engage the HFTO GREET "Train the Trainer" Fellowship. This Fellowship will last one year, with the opportunity to renew for additional years at the discretion of the sponsoring office. Your learning opportunities include:

  • You will be trained in the use of GREET to conduct life cycle analyses of hydrogen, biofuel, or vehicle technologies.
  • You will gain experience providing briefings and developing training materials on the use of GREET for external stakeholders.
  • You will learn and engage in critical aspects of HFTO's mission - mainly supporting Hydrogen Shot related activities, conducting technical reviews of Hydrogen Shot projects funded by the HFTO, drafting key documents summarizing program strategy and accomplishments, and technoeconomic analysis to inform program target-setting.
  • Under guidance of a mentor, you will organize workshops and conferences to solicit feedback from expert stakeholders on program direction and strategy, identify priority areas of research for future program activities, and give presentations at technical conferences and events to solicit stakeholder feedback on program activities.
  • You will gain a comprehensive understanding of key principles associated with life cycle analysis, and best practices being developed by organizations such as the International Partnership for Hydrogen in the Economy (IPHE) and the International Standards Organization (ISO).
  • You will gain a robust understanding of how to use the GREET model to conduct analyses of user-defined hydrogen systems, including hydrogen production, infrastructure, and end-use.
  • You will build strong communication skills through the development and delivery of briefing materials and training materials intended to enable external stakeholders (e.g. in industry) to utilize GREET for user-defined simulations.
  • You will learn about the performance of state-of-the-art hydrogen technologies, and how systems can be designed to enhance decarbonization potential.

These activities will be carried out in collaboration with a team of federal employees at all levels, other fellows, support service contractors, and National Lab experts.

Why should I apply? You will become part of a group of highly trained researchers, scientists, and engineers with the education, background, and experience to be part of the workforce that supports the DOE's mission in the future. The U.S. Department of Energy (DOE) Energy announced the Energy Earthshots Initiative aimed at accelerating breakthroughs of more abundant, affordable, and reliable clean energy solutions within the decade. The first Energy Earthshot, launched June 7, 2021—Hydrogen Shot—seeks to reduce the cost of clean hydrogen by 80% to $1 per 1 kilogram in 1 decade ("1 1 1"). Achieving the Hydrogen Shot’s $1/kg cost goal will enable new markets for hydrogen, including energy storage, steel manufacturing, clean ammonia, and heavy-duty trucks. Research programs within HFTO are guided by life cycle analysis using state-of-the-art tools, such as Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) model. Development of GREET has been funded by DOE Offices over the past two decades. The tool now includes hundreds of fuel pathways and is utilized by stakeholders worldwide across government, industry, and academia. GREET is also referenced in multiple provisions within the Inflation Reduction Act, and in solicitations issued in support of the Bipartisan Infrastructure Law.

Location: Washington, D.C.
