Deployment and Scale Up of Technologies for Deep Decarbonization: A Workshop

Project Scope:

The National Academies of Sciences, Engineering, and Medicine will appoint an expert committee of 4-6 members to plan and execute a workshop exploring the challenges and opportunities for deploying and scaling up technologies involved in deep decarbonization of the U.S. energy sector. Deep decarbonization in this context is reaching 80% or greater reduction in carbon emissions by mid-century. The workshop goal is to provide an understanding of how model assumptions and inputs for low emissions technologies represent real world conditions. Workshop participants will review several prominent published pathways for deep decarbonization and explore the technology development and deployment assumptions that underlie the modeled results. Workshop sessions will address specific classes of energy sector technologies, for example low carbon transportation, with the goal of understanding deployment and practical barriers faced in translating model assumptions to the real-world. The workshop will engage experts in modeling and development of decarbonization pathways with energy sector professionals with direct experience planning and managing energy technologies.

Dr. Larson’s interests include engineering, economic, and policy-related assessments of advanced clean-energy systems, especially for electric power and transport fuels production from carbonaceous fuels (biomass, coal, and/or natural gas) and for efficient end use of energy. His work addresses technologies of relevance to developed and developing countries. Larson maintains long-term collaborations on energy and sustainability with colleagues in China (Tsinghua University and the North China Electric Power University) and in Australia (University of Queensland). He has also participated in collaborative research efforts with colleagues across the United States and in Brazil, Cuba, India, Italy, Jamaica, Sweden, and elsewhere. He is currently collaborating with ecologists at the University of Minnesota and soil scientists at Colorado State University to better understand the potential of alternative biomass resource/conversion options to sustainably deliver negative carbon emission transportation in the US by mid-century. Larson was part of the Princeton team that contributed extensive analysis to the National Research Council report, America’s Energy Future: Technology and Transformation (2009). He was also the Co-Convening Lead Author of the Fossil Energy chapter of The Global Energy Assessment (2012) and a Lead Author (bioenergy) of the Renewable Energy chapter. Past research efforts have included ones focused on analysis of technology systems for modernizing renewable-biomass as an energy source, including advanced gasification-based technologies for power generation and for production of transportation fuels. These efforts have included assessments of potential gas-turbine based biomass electricity supply and use in sugarcane industries, in pulp and paper industries, and in stand-alone electric power generation. Recent work has focused on analysis of fossil fuel/biomass co-processing systems with CO2 capture and storage, for co-production of clean transportation fuels and electricity. Larson supervises student research and occasionally teaches courses in the engineering school at Princeton. Since 2008, he has also held an appointment as a Senior Scientist with Climate Central, a nonprofit, non-partisan science and media organization created to provide clear and objective science-based information to diverse audiences about climate change and its potential solutions.

Description :   

What does it take to scale deep decarbonization technologies and processes? How do we maintain a downward trajectory in CO2 emissions to meet ambitious reduction goals? Launching the new Deep Decarbonization Initiative, this workshop will explore the challenges and opportunities for deploying and scaling up technologies involved in U.S. deep decarbonization. Deep decarbonization in this context is reaching 80% or greater reduction in carbon emissions by mid-century. Speakers will explore issues for deep decarbonization of the U.S. economy through a focus on several key sectors such as electricity, transportation, food production, and heavy industry. The role of negative emissions technologies also will be considered. The discussions will include technology development, deployment, and scale-up; policy drivers, financing, and economics; and societal and the political economy implications.
