Technology CO2 Plume Geothermal can improve the efficiency of geothermal energy Bashny.Net

American experts presented a new geothermal technology, which enables 10-fold increase in electricity production using CO2 produced by plants running on fossil fuels.

American experts have proposed their idea of using CO?, emitted by plants using fossil fuels for electricity production. According to scientists, a new integrative technology, called CO? Plume Geothermal (CPG) allows you to pick up carbon dioxide from the atmosphere, thereby increasing the effectiveness of geothermal energy and reducing environmental risks.





The development of new technologies announced at the last meeting of the American geophysical Union, held at the end of last week. The advantage of the proposed solution is that it can be easily implemented in areas where previously, geothermal energy was not considered advantageous from an economic point of view. Developers: thanks to CPG can produce 10 times more geothermal energy compared to current traditional approaches. In this case the output is a new source of renewable energy which helps to reduce the amount of harmful carbon dioxide emissions into the atmosphere.

The essence of development is to use liquid carbon dioxide. In the beginning there is a capture CO?, allocated by source fossil fuel combustion — in this case we are talking about traditional power plants. For more effective storage of carbon dioxide is compressed to a supercritical state of the fluid can be pumped into the ground to a greater depth of 3.5 km, where sedimentary layers overlain by saline aquifers or exhausted oil fields.

 




The fact that CO? seeps through porous rocks much faster than water, absorbing at the same time without much effort a greater amount of heat. Moreover, carbon dioxide gas when heated expands more than water. Due to this property alone is sufficient natural pressure to bring the heated CO? back to the surface. As a result, there is no need to use pumps to restore the hot CO?, reducing energy costs needed to generate geothermal energy.





The traditional technology used today for hydropower around the world, severely restricts the use of ground to recover geothermal energy. New development of American specialists may be used in any territory, even if it is not enough underground storage tanks.

Moreover, CPG can be used in peak periods as an effective energy storage for intermittent solar and wind energy. published
