Taking sunlight and converting it to chemical bonds and then to electricity is one of the most promising carbon-neutral energy cycles. At the Chueh group, we are developing new materials to electrochemically convert energy between sunlight, fuel, and electricity. We take a rational approach towards materials discovery and optimization. Using powerful electron, X-ray and optical microscopy and spectroscopy techniques, we are “seeing” electrochemistry as they take place on length scales ranging from tens of microns down to below one nanometer. These never-before-seen dynamics lead to new insights into the design of functional materials with novel compositions and structures, such as those for water-splitting membranes, fuel cells, and batteries.

IMMEDIATELY AFTER THE ENERGY SEMINAR at 5:15 - 6:15 pm, GCEP invites Stanford faculty, students and staff to an informal poster session and energy social organized by GCEP students Boxiao Li and Haotian Wang in the Forbes Cafe area on the 1st floor of Huang.

Grid flexibility is a characteristic that is proposed to help the integration of variable renewable energy resources. However it has proven very difficult to quantify and this has spurred intense research efforts over the past few years. There are many sources, sinks and enablers for flexibility in the grid and these are all subject to numerous research challenges. Flexibility will be introduced, defined and a number of methods to quantify it will be described. This will be followed by an overview of research into unlocking flexibility in the power system e.g. demand side participation and power system operational strategies. There are potential hidden costs of flexibility and some of these will be highlighted, for example thermal plant cycling, and mitigation measures to reduce these will be formulated. Concluding remarks will try to give insights into how a future grid with very high penetrations of variable renewable energy may look like.

The Renewable Electricity Futures Study is  an initial investigation of the extent to which renewable energy supply can meet the electricity demands of the contiguous United States over the next several decades. This study explores the implications and challenges of very high renewable electricity generation levels--from 30% up to 90%, focusing on 80%, of all U.S. electricity generation from renewable technologies--in 2050.

At such high levels of renewable electricity penetration, the unique characteristics of some renewable resources, specifically geographical distribution and variability and uncertainty in output, pose challenges to the operability of the nation's electric system. The study focuses on key technical implications of this environment from a national perspective, exploring whether the U.S. power system can supply electricity to meet customer demand on an hourly basis with high levels of renewable electricity, including variable wind and solar generation. The study also identifies some of the potential economic, environmental, and social implications of deploying and integrating high levels of renewable electricity in the United States.
