When the UN Climate Conference was held in Doha, Qatar, there was a new way to reduce the carbon dioxide emissions of power stations by more than 90%. The system, currently in the planning stage, is about to be put into operation in an existing power station.
Researchers at the Darmstadt University of Technology in Germany spent four years studying carbon-based cyclic combustion methods. They currently manage one of the world's largest carbon dioxide capture systems. They have accumulated more than 1,000 hours of operational experience.
Researchers believe that this method uses less energy than previous technologies and costs less. The main advantage is that it can be installed in existing power stations.
Research on the method of circulating combustion of carbonates has received over 5 million euros in funding from the German Ministry of Economic Affairs and the industrial sector. In addition, the EU has also provided 1.5 million euros in funding.
The global CO2 emission trend report released this year pointed out that in 2011 global carbon dioxide emissions increased by 3% to 34 billion tons.
Bernd Eppler, head of research, said that this method is a milestone on the road leading to non-CO2-emitting power plants, which will make power plants using coal, natural gas, and biomass fuels reliable and profitable. Ways to generate electricity without damaging the environment.
Carbon dioxide capture and use technology is one of the fundamental technologies to reduce emissions and make power stations more environmentally friendly.
The Darmstadt University of Technology has studied a variety of innovative methods for capturing carbon dioxide. Researchers have been looking for ways to avoid carbon dioxide emissions while controlling energy consumption and operating costs.
Carbonate-cycle combustion uses natural limestone to collect carbon dioxide from power stations before it is processed and stored. This system is able to capture more than 90% of the carbon dioxide, saving more than 50% energy than the commonly used carbon dioxide capture method.
A number of studies and simulations have shown that this method can be successfully applied to larger systems. Researchers at Darmstadt University of Technology are applying the experience gained to a 20-fold system. The next phase of the plan is to install a larger system at an existing power station in Germany.
