Job Description

NREL is seeking a dynamic and self-motivated graduate-level intern focused on environmentally extended input-output (EEIO) analysis for its Circularity Futures (CF) project. The candidate shall contribute to methodology development and data processing to support the build-out of a coded hybrid physical-monetary EEIO model to address questions about the resource, economic, and environmental impacts of a growing circular carbon economy. Among the primary responsibilities are independent, self-guided compilations of life cycle inventory and techno-economic data for EEIO analyses and model development. The successful candidate will present and discuss data and model extensions with a project team and support the write-up of modeling results. The candidate is expected to work with the team to illustrate the developed methods in applied studies and manuscripts for submission to peer-review journals.

The successful candidate will join a team of researchers in NREL’s Strategic Energy Analysis Center (SEAC; who perform environmental sustainability assessments of energy technologies.
