A brand new study administered recently by Lawrence Berkeley Laboratory seems to indicate that by pumping carbon dioxide through hot rocks 2 totally different positive effects can be realized. 1st, this technique has the flexibility to get power, which has obvious effects in regards to this this modes of manufacturing power. Additionally to the current advantageous result, by propelling the carbon dioxide through the hot rock, these dangerous greenhouse gases that are created by fossil fuel power stations might be absorbed.

Karsten Pruess, the hydro-geologist at Lawrence Berkeley Laboratory who administered this studied, claims that “carbon dioxide may theoretically boost the number of energy created by hydrothermal plants by 50% or more….” and that “the technique may be used to dispose of the carbon dioxide created by conventional power plants, that contributes to global warming.”

So as to require management of the geothermal power, heat must be extracted from below the surface of the Earth. This new method being studied by Pruess can extract this heat a lot of efficiently than the present method, which involves water being pumped through the recent rocks and subsequently being extracted again.

Pruess’ hypothesis previous to utilizing the Soultz hydrothermal plant located in northwest France was that his technique would be additional resourceful than the plant’s method of pumping water. Though he wasn’t completely confident in this hypothesis prior to commencing the study, he learned that it is beneficial to take risks and attempt new solutions.

On top of the very fact that driving carbon dioxide through the new rocks produces a lot of energy by up to fifty p.c, it also necessitates less energy to be employed in enterprise the process. This is often because of the fact that the hot gas within the exit hole of the rocks is a smaller amount impenetrable than the cooler gas at the entry, subsequently that means reduced pumping would need to be done because of this density. Overall, this novel idea appears to be a win-win state of affairs relating to the proposal of a new type of renewable energy.

Allow us to additionally look to the second side of absorbing the dangerous greenhouse gas that carbon dioxide is. Per Pruess’ study, it appears to be inevitable that some amount of the gas would seep into the rock, storing the carbon dioxide. Although this seems like it would be an extreme positive, Robert Pine of the Camborne Faculty of Mines within the United Kingdom thinks there might be some adverse affects from this.

His take on it’s this: “While carbon dioxide is unlikely to flee from such traps, rock fractures, that are common in regions used for hydrothermal operations, might allow gas to leak out. Using gas fields might be higher, but as a result of they are not terribly hot you’d have to travel very deep to get to the heat.”

So, although he still seems to, normally, advocate the idea that Pruess has proprosed, in his opinion there are precautions that should be taken to confirm the foremost advantageous results from the new method.
