Carbon Capture: Sequestration and Storage (Issues in by Ronald E. Hester, Roy M. Harrison

By Ronald E. Hester, Roy M. Harrison

It's largely regarded that worldwide warming is going on because of expanding degrees of carbon dioxide and different greenhouse gases within the surroundings. tools of taking pictures after which storing CO2 from significant assets reminiscent of fossil-fuel-burning strength vegetation are being constructed to lessen the degrees emitted to the ambience by way of human actions. The ebook experiences on development during this box and gives a context in the diversity of typical absorption techniques within the oceans and forests and in soil. Comparisons with replacement strength assets comparable to sun and nuclear are made and coverage matters also are reviewed. This ebook, that is very topical because it affects at the lives of we all, is multi-authored via specialists making sure services around the complete diversity of this hugely technical yet mainstream topic. it truly is leading edge technology and know-how provided in a hugely readable shape besides an intensive bibliography.

Sample text

After all, the assumption that future generations will be wealthier and more advanced than our present generation is questionable. Geo-engineering approaches do not solve the problem of excess carbon but instead mask the symptoms for a time. However, as a bridging strategy they should be seen in a different light. For example, the world may decide that the current level of CO2 in the atmosphere is already higher than is affordable. Even with advanced technologies for removing carbon dioxide from the atmosphere, it would take decades to reduce the greenhouse gas concentrations to an acceptable level.

This land-use argument can be seen by comparing the energy collected by a solar panel in 30 years with the energy content of a 1 m-thick seam of coal below the land. In effect, the panel may produce about 30 GJ of electric power, while the coal seam may contain 30 GJ of chemical energy. Therefore, the land use in the two situations is not as different as it may appear at first sight. In mining a coal seam, it may take decades for the land to be reclaimed and in some cases it will never be reclaimed.

It is likely that solar energy will begin to play a larger and larger role, but its dilute nature makes it intrinsically more expensive than other options. vi A car engine, which comfortably fits under the hood of a car, is easily capable of producing in excess of 100 kW of power. This suggests that solar power could always feel strong competition from fossil fuels. The intermittent nature of solar energy also requires that solar electricity be cheaper than electricity that can be delivered on demand.
