The 21st Century Solar Army Center for Revolutionary Solar Photoconversion Seminar Series

submitted by: RASEIBoulder
Summary: The sun is a boundless source of clean energy, but it goes down every night. We and many others are trying to design solar-driven molecular machines that could be used on a global scale to store solar energy by splitting water into its elemental components, hydrogen and oxygen. Hydrogen is a clean fuel that could be used directly or combined with carbon dioxide to produce methanol, a liquid fuel. We are working on rugged light absorbers and catalysts made from Earth abundant...

How to Succeed in Bringing New Green Energy Technologies to Market

submitted by: RASEIBoulder
Summary: In our work at E Source we analyze lots of energy efficiency, renewable energy, and demand response technologies. The first thing we do is determine whether or not they are technically capable of providing the benefits that their vendors claim. That’s the easy part. We also have to make some judgment regarding whether the companies providing these technologies are likely to succeed at bringing them to market. Will they successfully attract, sell to, and serve large numbers of...

Carbon Capture and Storage: What Are the Big Issues and Opportunities for Future Energy Resources?

submitted by: RASEIBoulder
Summary: Carbon Capture and Storage (CCS) can make significant cuts in Greenhouse Gas emissions and will need to be part of the forward planning for developing future global energy resources. CCS technology comprises a number of steps: 1) CO2 is captured at the source (e.g., a power plant or gas production facility); 2) the captured CO2 is compressed to a supercritical state and transported, typically via pipeline, from the source to the geologic storage site; 3) the CO2 is injected via...

Materials - The Technology Barrier to Advanced Batteries for Energy Storage

submitted by: RASEIBoulder
Summary: Energy storage is the enabling technology for renewable energy, such as wind and solar, and particularly for the next generation of hybrid electric vehicles, the plug-in hybrid electric vehicle (PHEV). If long-lived, low cost and safe batteries are to be developed, the materials limitations must be overcome. Intercalation is the predominant reaction mechanism in rechargeable batteries in use today. Intercalation processes, unlike conversion reactions, allow for fast ionic motion...

Energy Supplies and Climate

submitted by: RASEIBoulder
Summary: An accurate estimate of the long-term production of oil, gas, and coal would be helpful for the ongoing policy discussion of alternatives to fossil fuels and climate change. It takes a long time to develop energy infrastructure, and this means that it matters whether we have burned 20% of our oil, gas, and coal, or 40%. In modeling future temperature and sea-level rise, the carbon dioxide from burning fossil fuels is the most important factor. The time frame for the climate response...

Diminishing Hype of So-called "Clean Coal": Carbon, Capture and Storage (CCS) in the U.S. Context

submitted by: RASEIBoulder
Summary: As the coal-reliant countries of the world have been increasingly forced to consider reducing carbon dioxide (CO2) emissions to mitigate climate change, carbon capture and storage (CCS) has emerged as a technology with critically important political influence. Visions of so-called "clean" coal-fired power plants that will not emit CO2 into the atmosphere have provided powerful motivation for large public and private investments in CCS. The scale of CO2 emission reductions deemed...

Change Is Inevitable, Except from a Vending Machine: The Dynamics of U.S. Energy Efficiency Politics and the Case of Residential Appliances

submitted by: RASEIBoulder
Summary: This talk looks at how energy politics change over time and the factors that influence how struggles over energy play out. I start out by building on two competing theories from environmental sociology that provide political economic explanations of environmental degradation and improvement: ecological modernization (EMT) and treadmill of production (TOP). Ecological modernization theory predicts that as capitalist nations develop the environment will improve. Treadmill of...
