Germans lead the world in implementing renewable energy infrastructure. But sometimes, there is too much of a good thing: the inability to store excess electricity reduces the efficiency of the renewable energy installations.
Meanwhile, carbon dioxide levels continue to rise, and hardly anyone doubts anymore that projects to pull carbon dioxide emissions out of the air will be a necessary transitional measure if the population of humans on Earth hope to continue energy-spurred growth while converting to renewable energy sources.
The Rheticus project offers solutions for both conundrums. Researchers from two German industrial giants, Siemens and Evonik, just announced that they will team up to demonstrate the feasibility of “technical photosynthesis.” The idea is to use eco-electricity and harness the power of nature to convert CO2 into more complex chemical building blocks, like the alcohols butanol and hexanol.
