BioThe availability of low-cost but intermittent renewable electricity (e.g., derived from solar and wind) underscores the grand challenge to store and dispatch energy so that it is available when and where it is needed. Redox-active materials promise the efficient transformation between electrical, chemical, and thermal energy, and are at the heart of carbon-neutral energy cycles. Understanding design rules that govern materials chemistry and architecture holds the key towards rationally optimizing technologies such as batteries, fuel cells, electrolyzers, and novel thermodynamic cycles. Electrochemical and chemical reactions involved in these technologies span diverse length and time scales, ranging from Ångströms to meters and from picoseconds to years. As such, establishing a unified, predictive framework has been a major challenge. The central question unifying our research is: “can we understand and engineer redox reactions at the levels of electrons, ions, molecules, particles and devices using a bottom-up approach?” Our approach integrates novel synthesis, fabrication, characterization, modeling and analytics to understand molecular pathways and interfacial structure, and to bridge fundamentals to energy storage and conversion technologies by establishing new design rules.

Dylan Marshall Crain
Ph.D. Student in Energy Resources Engineering, admitted Autumn 2022
Current Research and Scholarly InterestsMy current research revolves around optimizing the monitoring design of Carbon Capture and Sequestration (CCS) projects in such a way that the posterior (after data assimilation) predictions are as close to reality as can be hoped for.
In CCS projects within the U.S., it is important to have monitoring plan, which can consist of wells with pressure, saturation, salinity, et cetera sensors, seismic lines, or gravimetric above-ground measurements, before any injection has begun into the subsurface. This is due to the permitting requirements that must be satisfied before operations are begun.
Due to this constraint, any monitoring optimization (at least initially) needs to be determined using only a prior (highly uncertain) understanding of the subsurface. This makes the optimization much more challenging. We utilize a prior optimization scheme from a previous student which allows us to optimize a monitoring plan using only prior information to get the minimized, expected uncertainty reduction in the posterior models for a given quantity of interest. This scheme is limited by some Gaussian assumptions. We optimize it using a genetic algorithm.
From this point, with the monitoring plan established, the information gathered from the optimized monitoring scheme (using only monitoring wells at the moment) is used to history match (data assimilate) our understanding of the subsurface. The results can be used to predict the CO2 plume flow and behavior into the future.
This work was initially developed to assist a project in Illinois that is currently seeking Class VI injection well permits in the self-same state in order to begin injecting CO2 produced from two companies paying for the work from the Illinois Geological Survey. -

David Danielson
Adjunct Professor
BioDavid T. Danielson became a Precourt energy scholar at Stanford in 2016. With Stuart Macmillan and Joel Moxley, Dave co-teaches the yearlong course "Energy Transformation Collaborative." This project-based course provides a launchpad for the creation and development of transformational energy ventures. Interdisciplinary student teams research, analyze and refine detailed plans for high-impact opportunities in the context of the new energy venture development framework offered in this course.
Since January 2017, Dave has been managing director of Breakthrough Energy Ventures, a $1 billion fund focused on fighting climate change by investing in clean energy innovation.
From 2012 to 2016, Dave was assistant secretary of the U.S. Department of Energy’s Office of Energy Efficiency & Renewable Energy. There, he directed the U.S. government’s innovation strategy in the areas of sustainable transportation, renewable power, energy efficiency and clean-energy manufacturing, investing about $2 billion annually into American clean-energy innovation. He is considered a global expert in the development of next generation clean-energy technologies and the creation of new R&D and organizational models for high-impact clean energy innovation.
Prior to being appointed by President Obama as assistant secretary, Dave was the first hire at DOE’s Advanced Research Projects Agency– Energy (ARPA-E), a funding agency that focuses on the development of high-risk, high-reward clean-energy technologies. Prior to his government service, he was a clean-energy venture capitalist and, as a PhD student at MIT, was the founder and president of the MIT Energy Club. -
Steven J. Davis
Professor of Earth System Science, Senior Fellow at the Precourt Institute for Energy and Professor, by courtesy, of Energy Science and Engineering
BioSteve Davis is a highly-cited researcher and expert in earth system science, emissions and energy scenarios, climate impacts and solutions, and corporate climate strategy. He is a Professor of Earth System Science in the Stanford Doerr School of Sustainability and leads the Sustainable Solutions Lab, a research group dedicated to quantifying how different human activities are affecting climate and air quality, how those environmental changes in turn jeopardize human wellbeing, and the relative priority of solutions.
Steve was a Contributing Author of two Working Group III chapters in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), serves on the Scientific Steering Committee of the Global Carbon Project, was the Lead Author of the Mitigation chapter in the U.S. Fifth National Climate Assessment, and is a member of the Technical Council of the Science Based Targets Initiative.
Prior to his science career, Steve worked as a lawyer to venture-backed companies in Silicon Valley, and holds degrees from Stanford University, the University of Virginia School of Law and the University of Florida, where he double-majored in Political Science and Philosophy.
