Material Captures Carbon

Posted March 17, 2008 8:57 AM

From The Engineer:

US researchers have developed a new material for capturing carbon dioxide (CO2) from the chimneys of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide and can be reused many times. Existing CO2 capture techniques involve the use of solid materials that lack sufficient stability for repeated use, or liquid adsorbents that are expensive and require significant amounts of energy.

If this technology is cost effective, it puts a whole new spin on the need for alternative energy sources. Carbon based fuels are still the cheapest and there is no reason to not use alternative HC fuels if the pollution from emissions can be eliminated.

But this sequestration technique would apply mostly only to centralized power plants. Automobiles powered by internal combustion engines would continue to emit carbon dioxide (CO2) directly into the atmosphere. Removing CO2 at the power plants would certainly help towards the goal of reducing overall emissions, but we could really maximize the benefits of CO2 sequestration if we also switch to battery or fuel cell powered electric vehicles (limiting CO2 production to centralized power plants).
