“…Although an energy storage in batteries is already well known and popular, this technology is not viable for storing large amounts of energy or with a discharge duration longer than 4-8 h [49]. For large-scale and long-term energy storage, converting electricity to hydrogen is a more cost-effective option [50]. There are currently many types of fuel cells, consisting of three basic components: the two electrodes and the separating electrolyte.…”

This article presents the results of a comparative scenario analysis of the “green hydrogen” development pathways in Poland and the EU in the 2050 perspective. We prepared the scenarios by linking three models: two sectoral models for the power and transport sectors, and a Computable General Equilibrium model (d-Place). The basic precondition for the large-scale use of hydrogen, in both Poland and in European Union countries, is the pursuit of ambitious greenhouse gas reduction targets. The EU plans indicate that the main source of hydrogen will be renewable energy (RES). “Green hydrogen” is seen as one of the main methods with which to balance energy supply from intermittent RES, such as solar and wind. The questions that arise concern the amount of hydrogen required to meet the energy needs in Poland and Europe in decarbonized sectors of the economy, and to what extent can demand be covered by internal production. In the article, we estimated the potential of the production of “green hydrogen”, derived from electrolysis, for different scenarios of the development of the electricity sector in Poland and the EU. For 2050, it ranges from 76 to 206 PJ/y (Poland) and from 4449 to 5985 PJ/y (EU+). The role of hydrogen as an energy storage was also emphasized, highlighting its use in the process of stabilizing the electric power system. Hydrogen usage in the energy sector is projected to range from 67 to 76 PJ/y for Poland and from 1066 to 1601 PJ/y for EU+ by 2050. Depending on the scenario, this implies that between 25% and 35% of green hydrogen will be used in the power sector as a long-term energy storage.

“…There is a significant amount of existing research on r-SOC-based hydrogen energy storage in microgrids consisting of a few residential homes powered by solar photovoltaics (12)(13)(14)(15)(16). The r-SOC can be the sole energy storage system, or it can be hybridized with other technologies such as lithium-ion batteries or flywheels.…”

“…The r-SOC can be the sole energy storage system, or it can be hybridized with other technologies such as lithium-ion batteries or flywheels. These studies often optimize the sizing and dispatch of microgrid components for a given self-sufficiency ratio and report net present value (17), payback period (18), or levelized cost of storage (16). The r-SOC are not modeled in detail and tend to be described by their capacity, efficiency, ramp rate, and minimum load in both operating modes.…”

The use of green hydrogen to decarbonize the U.S. economy has been steadily gaining commercial interest as the cost and availability of renewable electricity decreases. At present, technologies can only take advantage of low electricity prices at low capacity factor, due to its intermittent availability, negatively impacting the economics. Reversible solid-oxide cell (r-SOC) based energy conversion systems can potentially solve this problem by producing power when electricity prices are high and hydrogen when they are low. However, the long-term operation of r-SOC systems has not been fully investigated compared to paired SOFC and SOEC units. This paper presents techno-economic results for two SOC-based hydrogen and power co-generation concepts. These technologies primarily generate hydrogen through solid oxide electrolysis but have the capacity to switch to power if signaled by the market. This operational flexibility provides a significant benefit to an electric grid with a growing share of variable renewable energy generation.
