But the use of biomass for energy generation combined with carbon capture and storage is less costly than chemical options, as long as sufficient biomass feedstock is available, the scientists point out. The low cost and low toxicity of CO2 make it an attractive industrial chemical reagent, and the utility of CO2 is dramatically illustrated by the fact that millions of tons of CO2 are consumed per year in the industrial production of urea. In the 1950s, when Calvin carried out his work, little was known about the details of photosynthesis and the idea that carbon dioxide was the feedstock for making plants' sugary foodstuffs wasn't widely accepted. Here is a link to article on USC News. (Detroit) has developed a process for converting eggshells into hydroxyapatite, the Aker Solutions will carry out extensive tests of emissions from Norcem's cement plant in Brevik, south Norway, to find the best chemical solvent for capturing carbon dioxide, the main greenhouse gas. Has stepped up its offensive against a group that says the oil giant poisoned sections of the Amazon rain forest. The same is applicable to the other so-called traditional by-product sources of CO2 feedstock from other chemical and energy processes and sources. Hal Harvey writes about an important caveat in the work:. Rather than treating CO2 as waste, it can be regarded as a chemical feedstock for the synthesis of other chemicals that do not rely on a petrochemical source. Though the work is ongoing, Olah and Prakash hope to find a low-cost, low-energy method of turning the captured carbon dioxide into methanol – which can be burned as a fuel source and used as a chemical feedstock. Eggshells serve as feedstock for hydroxyapatite production. Alternatively, instead of storage, the captured CO2 could be used as a chemical feedstock to produce carbon-based fuels and chemicals when combined with renewable hydrogen produced using additional wind energy. Though the work is ongoing, Olah and Prakash hope to find a low-cost/low-energy method of turning the captured carbon dioxide into methanol - which can be burned as a fuel source and used as a chemical feed-stock. In addition, the researchers hope to find a low-cost method of turning the CO2 into methanol, a fuel and a chemical feed stock. Gasification is a process through which coal can be transformed into power, chemicals, hydrogen and transportation fuels, capturing the resulting carbon by-product from the coal for sequestration or for enhanced oil recovery. Scientists at the US Department of Energy's National Renewable Energy Laboratory in Golden, Colorado, have succeeded in turning carbon dioxide into ethylene, an energy-dense fuel and most widely produced feedstock for the . Achieve dramatic lower emissions levels, as the syngas produced is at higher temperature and pressure, which allows for easier removal of sulfur (SOX), nitrous oxides (NOX) and lends itself to efficient carbon dioxide (CO2) removal as well.
