Abstract
Despite being widely used in the fuel and fertilizer production and as raw material in several chemical processes, only now hydrogen has been gaining importance. The most used process for hydrogen production, steam methane reforming (SMR), has significant CO2 emissions (9.5kgCO2/kgH2) despite the absence of carbon in its molecule. Processes that make use of renewable energy combined with hydrolysis of water are still excessively expensive for large scale production and suffer with the intermittency related to most of these energy sources. This work proposes offshore production of hydrogen via SMR with reduced CO2 emissions. The production of hydrogen on oil and gas platforms, or on near barges, aims to make use of the natural gas produced, sea water for the production of steam and as cooling media and the oil and gas wells for CO2 capture. Furthermore, the pipe transportation of the final product (H2) instead of natural gas requires about 30% less energy. These synergies are evaluated in this paper, from an energetic and environmental perspective, in order to find a viable solution to the growing demand for hydrogen.
