Christopher Yang is a research scientist working within the Sustainable Transportation Energy Pathways program at ITS-Davis and a Faculty member in the Transportation Technology and Policy graduate program. His research focuses on analysis of alternative fuels and advanced vehicles and their role in reducing transportation greenhouse gas emissions, with an emphasis on hydrogen and electricity supply and infrastructure.
Current research projects include (1) infrastructure modeling of electricity and hydrogen supply to understand the implications (i.e.  supply mix, cost and emissions) of increasing use of these energy carriers as transportation fuels; (2) energy system modeling to understand the role of technologies and energy resources across many end-use and supply sectors in achieving very deep reductions in greenhouse gas emissions in California (i.e. CA-TIMES model) and (3) the broader role of transportation in meeting these emissions targets.

He is a co-director for infrastructure system analysis research within the STEPS/NextSTEPS program.

TTP 289A-002 Energy Modeling for Policy Analysis

The course will familiarize students with building energy models for policy analysis. We will explore several facets of energy systems modeling including supply and demand, energy technologies, emissions, technological change and diffusion, scenario analysis, and uncertainty. We will also introduce techniques for policy analysis. The students will learn to integrate multi-disciplinary knowledge, build analytical tools, conduct alternative scenario analysis, and carry out sensitivity and uncertainty analysis. The student will be introduced to several genres of energy models and will be required to complete a number of model building exercises using Excel, other tools introduced in class, or developed by students based on his/her own skills (advanced knowledge of computer programming is not a requisite for this class). Students will become familiar with forecasting energy use and demands, gain experience of building techno!economic models, and develop skills for policy analysis. Assignments will draw on real-life policy problems at the state, federal, and international level.
