Dr. Hanna Breunig is a Research Scientist and Deputy-Head of the Sustainable Energy and Environmental Systems Department in the Energy Analysis and Environmental Impacts Division. She holds a secondary joint appointment in the Earth Systems and Society Domain in the Climate and  Ecosystem Science Division. Hanna specializes in techno-economic analysis, process modeling, market analysis, and environmental and human health impact assessment (life-cycle assessment) of emerging energy and negative emissions technologies. These include high temperature thermal energy storage, bioenergy, enhanced weathering, and gas (H2, CO2, CH4) capture, production, storage, utilization, and management technologies. She holds a B.Sc. in Environmental Engineering from Cornell University and an M.Sc. and Ph.D. in Civil and Environmental Engineering from UC Berkeley.


Hanna leads a monthly TEA/LCA working group for LBL staff and affiliates. The group hosts discussions on conventional and emerging methodologies,  datasets, and tools, troubleshooting, and mini presentations.

Early Career Development LDRD Awards -  November 30th 2017

Hanna Breunig and Anna Spurlock, have been awarded new Early Career Development awards, as part of the Laboratory-Directed Research and Development Program. The award will fund each scientist’s salary and research expenses for the next two years:

  • Hanna Breunig: "Mitigating Fossil Fuel and Microbial Methane With New Materials for Distributed Energy Generation"
  • Anna Spurlock: “A Neuroeconomics Experiment to Study Routine Transportation Decision-Making Processes and Drivers”

The Early Career Development track within the LDRD Program is intended to help Lab scientists begin leading their own research, and could help them prepare to compete for DOE-funded awards such as the DOE Early Career Research Program awards.

Schmidt MacArthur Fellowship -  March 05th 2014

Breunig is a graduate student researcher in the Sustainable Energy Systems Group's emerging technology analysis group, Environmental Energy Technologies Division, and a PhD candidate in the Department of Civil and Environmental Engineering at the University of California, Berkeley. She is one of 16 Schmidt-MacArthur fellows in the class of 2014.

The Schmidt-MacArthur Fellowship is an international postgraduate fellowship on the circular economy for design, engineering and business students. The Fellowship programme, a joint initiative between the Ellen MacArthur Foundation in the U.K. and the Schmidt Family Foundation in the U.S., offers an innovation platform for postgraduate students and academics from leading international design, engineering & business schools to redesign the economy.

As mentor to Breunig, Sustainable Energy Systems Group Leader Thomas McKone was also honored by the Schmidt-MacArthur selection committee.
