A biological and chemical method for the capture and conversion of carbon dioxide into organic compounds, comprising: introducing carbon dioxide gas, either alone and/or dissolved in a mixture or solution further comprising carbonate ion and/or bicarbonate ion into an environment suitable for maintaining chemoautotrophic organisms and/or chemoautotroph cell extracts; and fixing the carbon dioxide and/or inorganic carbon into organic compounds within the environment via at least one chemosynthetic carbon fixing reaction utilizing chemoautotrophic microorganisms comprising a Ralstonia sp.; wherein where the chemosynthetic carbon fixing reaction is driven by chemical and/or electrochemical energy provided by electron donors and electron acceptors that have been generated chemically and/or electrochemically and/or are introduced into the environment from at least one source external to the environment, and wherein the electron donor comprises hydrogen generated through an electrolysis method selected from the group comprising proton exchange membrane electrolysis, liquid electrolyte electrolysis, high pressure electrolysis, and high temperature electrolysis of steam and said electron acceptor comprises carbon dioxide and/or oxygen; wherein the environment suitable for maintaining chemoautotrophic organisms and/or chemoautotroph cell extracts is maintained using continuous influx and removal of nutrient medium and/or biomass, in substantially steady state where the cell population and environmental parameters are targeted at a substantially constant suitable or optimal level over time; and wherein biomass is produced by the at least one chemosynthetic reaction, and wherein the biomass is separated from the environment and is processed into a product comprising an animal feed, a fertilizer, a soil additive, a soil stabilizer, a carbon source for large scale fermentations, a nutrient source for the growth of other microbes or organisms, and/or as a source of pharmaceutical, medicinal or nutritional substances. introducing carbon dioxide gas, either alone and/or dissolved in a mixture or solution further comprising carbonate ion and/or bicarbonate ion into an environment suitable for maintaining chemoautotrophic organisms and/or chemoautotroph cell extracts; and fixing the carbon dioxide and/or inorganic carbon into organic compounds within the environment via at least one chemosynthetic carbon fixing reaction utilizing chemoautotrophic microorganisms comprising a Ralstonia sp.; wherein where the chemosynthetic carbon fixing reaction is driven by chemical and/or electrochemical energy provided by electron donors and electron acceptors that have been generated chemically and/or electrochemically and/or are introduced into the environment from at least one source external to the environment, and wherein the electron donor comprises hydrogen generated through an electrolysis method selected from the group comprising proton exchange membrane electrolysis, liquid electrolyte electrolysis, high pressure electrolysis, and high temperature electrolysis of steam and said electron acceptor comprises carbon dioxide and/or oxygen; wherein the environment suitable for maintaining chemoautotrophic organisms and/or chemoautotroph cell extracts is maintained using continuous influx and removal of nutrient medium and/or biomass, in substantially steady state where the cell population and environmental parameters are targeted at a substantially constant suitable or optimal level over time; and wherein biomass is produced by the at least one chemosynthetic reaction, and wherein the biomass is separated from the environment and is processed into a product comprising an animal feed, a fertilizer, a soil additive, a soil stabilizer, a carbon source for large scale fermentations, a nutrient source for the growth of other microbes or organisms, and/or as a source of pharmaceutical, medicinal or nutritional substances. <EOS>
