Brentan Alexander, PhD


Dr. Brentan Alexander joined New Energy Risk in 2012 as chief science officer and began serving also as chief commercial officer in 2019 and then president in 2021. As a serial entrepreneur, academic, and respected researcher, Brentan has developed the deep expertise to rapidly perform detailed technical diligence on novel technologies. He is an expert in the fields of thermochemistry, electrochemistry, heat and mass transport, and thermodynamics, and has devoted his career to advancing the deployment of clean energy technologies.

Prior to joining New Energy Risk, Brentan worked as an independent engineer for Veryst Engineering and Exponent. There, he tackled projects in failure root-cause analysis, manufacturing quality control, validation test design, engineering design review, and technology R&D for clients including Shell, Microsoft, BP, General Motors, and Columbia Sportswear. His entrepreneurial endeavors include founding Swift Calcs, a web-based technical computing platform for faster and more reliable engineering calculations, as well as EnergyFolks, a nonprofit professional network connecting energy students and professionals in their area. He also was senior mechanical engineer at Wrightspeed, a startup developing next-generation hybrid-electric powertrains for medium- and heavy-duty trucks.

Brentan received his PhD from Stanford University in Mechanical Engineering, where he focused on solid fuel gasification and syngas utilization using solid-oxide fuel cell technology. He is the author of numerous peer-reviewed scientific publications, has presented at a variety of technical symposia, and has been honored as an NDSEG Fellow (2009-2012) and a Rohsenow Fellow (2007-2008). He holds MS and BS degrees in Mechanical Engineering from MIT.

When he’s not geeking out on the latest gasification kinetic models, you can find him outside, hiking the East Bay hills or lounging on the deck with his daughters.
