| |OCTOBER 20229advancements in purification, use of microorganisms, and conversion of byproduct CO2 into methane have helped improve the methane content in biogas. BEKON GmbH and Renergon International AG have developed innovative biogas technologies, while Krajete GmbH and Trovant Technology have introduced technologies for the conversion of CO2.CO2 is one of the main contributors to global warming. Some companies have reportedly developed processes for the production of fuel from captured CO2. Captured carbon emissions are converted into liquid fuels electrochemically, in a process based on electrolysis and use of catalyst. Companies like Carbon Engineering Ltd., Climeworks AG, and Drax have either developed or are engaged in developing a commercial process to produce fuel. Redesigning of gasification reactors has also helped companies to develop sustainable thermochemical processes. Companies like Enerkem and Fulcrum BioEnergy have developed advanced gasification processes. Several other companies have either developed or are currently developing processes to produce sustainable fuels.Sustainable fuels have a minor share among fuels consumed globally but help in reducing toxic emissions, mainly from the transportation sector. Advancements in fuel technologies can significantly reduce the cost of sustainable fuels. This will play an important role in achieving the target of complete replacement of fossil fuels, ensuring energy security and reducing global warming.
