Carbon Sequestration – an optimal clean technology?

Wednesday, May 27th, 2009

While coal-fueled power plants are directly responsible for roughly one-third of our CO2 emissions, the DOE indicates that coal is expected to dominate our domestic power generation at least for the next 25 years.  Globally, the increased demand for coal-fueled electricity will translate into a 57% rise in related CO2 emissions by 2030 according to the IEA.

One technology that attempts to solve the CO2 emissions crisis is carbon capture and storage, or CCS. Generally speaking, CCS captures the CO2 emissions from coal power plants and other industrial sites and injects the CO2 into underground porous rock formations in hopes of permanent sequestration.

Wind Energy: Bird kills on the radar

Monday, May 11th, 2009

A DeTect system in use elsewhere in TexasA colleague of mine said to me recently, “No energy is clean energy.”

Which got me thinking. Of course, Clean Coal comes to mind. And people love to say that “No coal is clean,” and “Clean Coal is an oxymoron.”

OK, OK. It’s not the best marketing term I’ve ever heard. There is a U.S. Department of Energy program that uses the term, and that program has funded gasification and carbon sequestration projects. So there is such a thing, whatever you want to call it. How about “Clean(er) Coal”?

Then I thought about wind. Big, majestic, white turbines … cutting up birds that fly into them. Whoops. That’s not very clean.
