In the near future, carbon based value chains will not longer be based solely on fossil feedstocks, but to a large extent on alternative carbon feedstocks like biomass and (biogenic) CO2 (e.g. captured from flue gases from waste-to-energy plants). CO2 as feedstock requires a large quantity of hydrogen for conversion, first to CO and syngas as intermediates and further to methanol and ultimately to materials and synthetic fuels. A major challenge is the source of the green hydrogen, and the associated costs, especially when produced in NW Europe. Therefore, green hydrogen will be imported from regions with affordable and abundantly available renewable energy (e.g. North Africa, Chili) in the form of a liquid hydrogen carrier, most probably as ammonia (NH3). Liquified ammonia will be received in ports in NW Europe where a part will be reformed back to hydrogen gas, as feedstock for chemical processes. Conversion of (biogenic) CO2 to CO as intermediate will be a major application that can be integrated with the reforming of ammonia to hydrogen in a single process, using the a chemical looping concept developed by TNO. This novel technology has benefits on cost and on composition and purity of the produced CO.
