Options being developed globally include the biochemical conversion of CO2 into algal biofuel, the thermochemical conversion into methanol and the biocatalytic or solar photocatalytic conversion of CO2 to fuels.
Carbon capture and storage (CCS) is being hailed as the answer to the globe’s most pressing question: what to do with the 27 billion metric tons of carbon dioxide emitted yearly from the burning of fossil fuels? Touted as the most promising interim solution to deal with the greenhouse gas responsible for global warming, CCS still remains unproven, costly and will not be commercially available for another 10-20 years. Meanwhile scientists are exploring alternatives to CCS by capitalizing on CO2 as a commodity instead of treating it as a waste.
