Tessa Weiss

Senior Associate
  • Climate Aligned Industries

Tessa is a Senior Associate on RMI’s Climate Aligned Industries Program where she works to support the advancement of hydrogen to decarbonize the ‘hard to abate’ sectors with a focus on steel manufacturing, fertilizer production, and maritime shipping. She leads technoeconomic analysis on green hydrogen’s production, storage, transport, and optimized system design to understand the cost competitiveness of the technology, assessed the lifecycle emissions of various hydrogen production pathways, evaluated the priority uses of hydrogen, and supports the development of hydrogen hubs.


Prior to joining RMI, Tessa studied mechanical engineering at the Massachusetts Institute of Technology (MIT). There she gained a broad understanding of various clean energy technologies by designing small-scale nuclear reactors, analyzing the energy efficiency of buildings, researching thin film solar cells, and modeling urban energy flows. She also led the student engagement team at ClimateVoice, a nonprofit that mobilizes the workforce to encourage companies to take action on climate.
