"Carbon Sciences believe they have made a breakthrough with their technology, which they say can transform CO2 back into basic fuel building blocks efficiently.
Their biocatalytic process converts CO2 into basic hydrocarbons - C1 (methane) C2 (ethane) and C3 (propane) -- which can then be utilized to make higher-grade fuels like gasoline and jet fuel."
As we've been saying, there are ways to make the by-products of coal use - especially those from CTL conversion processes - valuable as raw materials for other processes.
Another excerpt, concerning one of our own, respected, national laboratories:
"Scientists at Sandia National Laboratories in New Mexico are exploring the idea of using concentrated solar energy to turn CO2 into fuel. The Sunshine to Petrol project is testing a prototype device called the Counter Rotating Ring Receiver Reactor Recuperator (called CR5 for short) which turns CO2 into carbon monoxide which could then form part of a liquid fuel."
So, whether or not humans or volcanoes contribute more CO2 to the environment, we don't have to dump any more than we are right now in order to continue using coal, and to broaden it's use as a feedstock for liquid fuel conversion and chemical manufacture.
We can, and should, capture and use the Carbon Dioxide.
The overall objective of this project is to address the following issues: 1. CO2 supply from fuel combustion systems.(a) characterize representative types of industrial flue gas, (b) determine, based on typical gas composition, what separation and clean-up technologies may be necessary, and (c) determine the best techniques to assure maximal dissolution of CO2 in the flue gas into algal growth medium. 2. Selection of microalgae. The participants shall select microalgal species best suited for CO2 sequestration based on (a) their growth rates and rates of carbon fixation, (b) ability to mineralize CO2 into inorganic forms such as carbonates, (c) content of high value products, (Hmm - wonder what that means? - JTM) and (d) ability to withstand noxious components in flue gas mixtures.
As we've already noted for you multiple times, you can make suitable diesel and jet fuel from algae, and a number of airlines have already made demonstration flights with it. And, if the right coal conversion process is selected, the algae, with minimal pre-treatment, can be dumped right into the in-box of a CTL plant, along with the coal and some previously-discarded coal mine waste, and forestry and agricultural products/by-products.
