The oil and gas industry has set out to develop low-carbon and cost-efficient production systems. In Norway, 25% of the CO2 -emission comes from the oil and gas production. CO2-emission from generation of energy to drive compressors and pumps often represents more than 90 % of the total emission from offshore production systems. REINERTSEN New Energy has developed a new concept for “Pre-combustion CCS” suitable for deployment on offshore platforms (< 100 MW). The clean and efficient production of hydrogen is made possible by compact reformer-technology and Palladium membrane separators. The hydrogen is to be used as fuel in new or modified turbines, or in future fuel-cells.

Another concept, the EFHP (Emission Free Hydrogen Production), has been developed for large-scale and clean hydrogen production on-shore, with CCS. Clean and competitive power can be supplied from shore to platforms and subsea facilities. The building of a large demo-plant is being considered. The paper will discuss how the “life of field” energy consumption and economy for the oil- and gas fields can be optimized. The economics, including CO2 -void cost will be presented. The new hydrogen and CCS solutions require subsea pipelines, infrastructure, production-facilities, and subsea wells. The state of the art of storage and transportation of hydrogen, and the transportation, injection and storage of CO2 will be presented. The potential for new, Norwegian (subsea) gas projects to serve the new hydrogen markets will be discussed, together with the need to bring forward new technology and innovative solutions.
