Within the past couple years, engineers have been able to come up with a way to produce 10 times the amount of electricity using CO2 from fossil fuels from the power of geothermal energy. For those who do not know what geothermal energy is, it is using the natural heat of the Earth to produce electricity and heat by sending water into the ground.
The water then heats up and comes back to surface as steam which then goes through a machine that produces electricity or heat. This new method could revolutionize the way people get power all around the world. This system is actually quite simple. These geothermal energy plants will take CO2 directly from fossil fuel burning plants and convert it into a liquid state. In this liquid state, these geothermal energy companies will then pump this liquified CO2 into the ground.
One quality that liquid CO2 has over traditionally used water for geothermal energy is the fact that CO2 can flow through porous rock faster than water, which means more heat can be tapped. The CO2 then turns back into a gas and goes through a machine, much like water, to produce electricity and heat(CITE). The best part of this is the fact that is can be used all over the world to help provide electricity everywhere. This could lead to a much more environmentally friendly world.
