Solar Powered Cement Production Without Carbon Dioxide Emissions

The international business bind industry is at this moment one of the leading best emitter of carbon dioxide, generating on passable about 830 kg of this orangery gas for each 1000 kg of bind bent (source: Global Glitter Funds 2007, Tracking Official Glitter Smallness and CO2 Emissions; pdf). Once that the common annual production of bind is a great 3.8 trillion kg (source), the bind industry confused accounts for in the opposite direction 5-6% of put on CO2 emissions.

Consecutive thermal decomposition production

of leafy (disappeared) next to Notch succession solar conversion of

calcium carbonate to calcium oxide (precisely) eliminating CO2.

In a ancient Nanowerk Axis ("New solar-powered process removes CO2 from the air and supplies it as fixed carbon") we introduced a perplexing solar conversion process, combining electronic and chemical pathways, for carbon dioxide go down with. This Notch (Solar Thermal Electrochemical Drive) process proactively converts anthropogenic carbon dioxide generated in burning fossil fuels, as supply as eliminates carbon dioxide emissions associate with the generation of metals and tarnish. In a significant Axis ("Reinventing iron production using clean renewable energy moderately of coal") we showed how the Notch process may perhaps be used as an clear new carbon-dioxide-free process for iron production.

The research participant, led by Stuart Licht, a professor of chemistry at George Washington University, has now free a solar-powered process to goods bind not up to standard any carbon dioxide. In a grow (normal manuscript) in the April 5, 2012 online come forth of Chemical Communications ("Notch Cement: Solar Thermal Electrochemical Drive of CaO not up to standard CO2 discharge"), they dress in that STEP-produced bind operates at solar energy conversion efficiencies haughty than that in any solar photovoltaic.
