Science Nation - Waste to Energy

submitted by: nsf
All of us use water and in the process, a lot of it goes to waste. Whether it goes down drains, sewers or toilets, much of it ends up at a wastewater treatment plant where it undergoes rigorous cleaning before it flows back to the environment. The process takes time, money and a lot of energy. What if that wastewater could be turned into energy? It almost sounds too good to be true, but environmental engineer Bruce Logan is working on ways to make it happen. Most treatment plants already use...

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...

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...

MWV Episode 59 - Anne K. Jones - Cyanobacteria's Potential as a Fuel Product

submitted by: MicrobeWorld
In episode 59 of MicrobeWorld Video, filmed at the American Association for the Advancement of Science Meeting in Vancouver, BC Canada on February 17, 2012, Dr. Stan Maloy talks with Anne Jones, D. Phil., Assistant Professor, Department of Chemistry and Biochemistry, Center for Bioenergy and Photosynthesis, Arizona State University, about why her research into harvesting excess light energy has promising potential as an energy alternative. Anne explains why photosynthesis is an...
