“…[2]. In an urban example in Germany the current limit on the hydrogen fraction implies a limit on the economic performance of decentralized power-to-gas stations [11]. With an eye towards a future in which a higher hydrogen fraction, preferably with straightforward grid operation, is realizable, it is essential that one anticipates this future by developing compliant gas appliances.…”

“…Finally, in Section 5 appliance approval and nationally regulated gas distribution are addressed for NG/H 2 mixtures. The limits set by current conditions are challenged to explore directions of appliance development and research to extend the possibilities for hydrogen admixture, based on the physical-chemical principles underlying the methods, thus providing hydrogen levels for increased economic performance in the field of power-to-gas [2,10,11]. Moreover, grid management issues are addressed, for the cases of variable and constant hydrogen fractions, and related to energy availability for the end user.…”

“…For this reason, different energy storage technologies have been developed for several applications, in particular to avoid curtailment of power production, and to support stable operations of electric grids (Fischer et al, 2018b;Koohi-Fayegh and Rosen, 2020). To compensate for production fluctuations as well as providing benefits at the system level (e.g., control reserve energy), H 2 based storage systems have been proposed (Grueger et al, 2017).…”

Techno-Economic Assessment of Demand-Driven Small-Scale Green Hydrogen Production for Low Carbon Agriculture in Sweden

Wind power coupled to hydrogen (H2) production is an interesting strategy to reduce power curtailment and to provide clean fuel for decarbonizing agricultural activities. However, such implementation is challenging for several reasons, including uncertainties in wind power availability, seasonalities in agricultural fuel demand, capital-intensive gas storage systems, and high specific investment costs of small-scale electrolysers. To investigate whether on-site H2 production could be a feasible alternative to conventional diesel farming, a model was built for dynamic simulations of H2 production from wind power driven by the fuel demand of a cereal farm located on the island of Gotland, Sweden. Different cases and technological scenarios were considered to assess the effects of future developments, H2 end-use, as well as production scale on the levelised- and farmers’ equivalent annual costs. In a single-farm application, H2 production costs varied between 21.20–14.82 €/kg. By sharing a power-to-H2 facility among four different farms of 300-ha each, the specific investment costs could be significantly decreased, resulting in 28% lower H2 production costs than when facilities are not shared. By including delivery vans as additional H2 consumers in each farm, costs of H2 production decreased by 35% due to the higher production scale and more distributed demand. However, in all cases and technological scenarios assessed, projected diesel price in retailers was cheaper than H2. Nevertheless, revenues from leasing the land to wind power developers could make H2 a more attractive option even in single-farm applications as early as 2020. Without such revenues, H2 is more competitive than diesel where power-to-H2 plants are shared by at least two farms, if technological developments predicted for 2030 come true. Also, out of 20 different cases assessed, nine of them showed a carbon abatement cost lower than the current carbon tax in Sweden of 110 €/tCO2, which demonstrate the potential of power-to-H2 as an effective strategy to decarbonize agricultural systems.
