Carbon in Fractions: CoolPlanet Makes Renewable Biofuels and Sequesters Carbon

Tuesday, February 7th, 2012

CoolPlanet Energy Systems (CoolPlanet) is a Camarillo, California, company that is developing a “negative carbon” drop-in gasoline replacement fuel from biomass.

According to the company’s web site, the fuel is made using proprietary biomass fractionator (more…)

Biochar Value to Glacial Soils and Greenhouse Gases

Friday, December 16th, 2011

Adding a charred biomass material called biochar to glacial soils can help reduce emissions of the greenhouse gases carbon dioxide and nitrous oxide, according to U.S. Department of Agriculture (USDA) scientists. Studies by scientists with USDA’s Agricultural Research Service (ARS) are providing (more…)

Carbon Sequestration – Balancing Property Rights and the Public Good

Thursday, October 13th, 2011

Carbon sequestration is the capture of carbon dioxide (CO2). This is the process of carbon capture and storage, where carbon dioxide is removed from flue gases, such as on power stations, before being stored in underground reservoirs. There are also natural sequestration processes such as the ocean. (more…)

Carbon Capture and Storage: A Long-Term Solution for Natural Gas?

Monday, June 20th, 2011

If natural gas is a “bridge fuel,” what’s on the other side?

This question kept popping up in recent weeks as a series of reports predicted gas would become a growing part of the global energy mix in the coming decades. Gas, while cleaner burning than coal, still falls short of the low-emissions scenarios envisioned by world leaders, (more…)

What is Biochar?

Wednesday, August 11th, 2010

Biochar is charcoal type created by the pyrolysis of biomass, and differs from ordinary charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage. As much as 12 percent of the world’s human caused greenhouse gas emissions could be sustainably offset by producing biochar. (more…)

Monitoring the Sequestration of Carbon Dioxide

Thursday, June 17th, 2010

Global Warming is caused by several factors such as the release of greenhouse gases like carbon dioxide into the atmosphere. One solution to the problem is to capture the carbon dioxide before it enters the atmosphere, and instead, deposit the CO2 into the ground. However, up to this point, scientists have been unable to effectively track how it might move underground. The desire is to get the CO2 in place and not have it move elsewhere and potentially cause problems. Now, with the advent of Electrical Resistivity Tomography (ERT), developed at the (more…)

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.
