Title: Techno-economic analysis of green H2 production and Power-to-X pathways: future energy solutions for the HSY Ämmässuo eco-industrial centre
Authors: Cardarelli, Paolo
Abstract: From a sustainability perspective, a synergy between hydrogen production and renewable energy sources is particularly attractive. Considering the many potential end uses of hydrogen, the implementation of Power-to-X has become one of the most relevant technologies for reaching a carbon-free future. This master’s thesis sets off with a detailed description of the core concepts necessary for the assessment, such as the hydrogen colour code, the H2 production methods (with a focus on electrolysis) and the Power-to-X concept. After this, a general description of the HSY Ämmässuo eco-industrial centre is provided, to offer a perspective of the energy self-sufficiency issues that need to be solved, for both heat and electricity production. The possible future energy scenarios of the eco-centre are then analysed, for which the implementation of renewable energy sources would simultaneously ensure its self-sufficiency and open the possibility of green hydrogen generation via electrolysis. Since various investments are considered to achieve said objectives, the economic perspective is of upmost importance: the potential assets’ feasibility is studied, considering both their payback period and the effective benefits that can be brought to the eco-centre. The results of the work show that, while it is possible to simultaneously achieve energy self-sufficiency by implementing additional renewable sources and to invest in an electrolyser for hydrogen production, the generation of compounds such as methanol or methane is not feasible in the near future. Four energy scenarios of increasing complexity are analysed, which indicate that the installation of a wind turbine and solar panels would be a useful asset, while the acquisition of a hydrogenation system for the production of methanol or methane would not be feasible with the amount of surplus energy at disposal of the eco-centre.
