The commercial application of the technology “Power to gas” climate protection goals of the federal government to achieve cost-effective. That is the conclusion of a new study by the Fraunhofer Institute for Solar Energy Systems ISE (Freiburg).
The researchers conclude that failed in the substantial reduction of carbon dioxide emissions, the total annual cost of the German energy system to a high double-digit billions lower when the memory technology the future will be expanded accordingly.
The model of the research group of Prof. Hans-Martin Henning provides comprehensive basis for up to 2016 to be established by the Federal Government Climate Protection Plan 2050 will be demonstrated in him, what specific measures are necessary, the greenhouse gas emissions in Germany by 2050 to reduce by at least 80 percent below 1990 levels. One thing is already clear: Power to gas, it becomes easier to achieve the targets without drastic cost increases.
Power to gas does not increase the cost of energy, but lowers it
So far has been controversial whether power-to-gas increases the cost of the energy revolution or rather lowers. Now do scientific evidence regarding this issue: if the carbon dioxide emissions in 35 years with the help of the commercial development of power-to-gas by 75 to 82 percent, which is associated with much lower economic costs, the ISE study, the experience draws on several power-to-gas projects. At 80 percent reduction summed up as the savings compared to a system without energy storage technology, to 60 billion euros per year; at 82 percent it were even around 90 billion euros.
The investment required to build the capacity would soon pay for themselves: In a 80-percent reduction they pay for themselves in less than five years, 82 percent faster, according to the study ,
“We need the technology for a climate-friendly and affordable energy supply. That the study clearly shows, “says ETOGAS Managing Director Gregor Waldstein. “We have adequate capacity and the desired cost structure in the future, we must ask the industrial and energy choices now. Otherwise it will be more expensive. ”
More information on the new study, there are up to March 11 at the “Energy Storage Europe” in Dusseldorf on ETOGAS stand.
