“…Still, the exploitation of hydrogen cavern storage in northern and central Germany, as well as the installation of a pipeline infrastructure from northern to western and southern Germany, is a robust result across this and previous analyses. The sensitivity of the infrastructure design to changes, in decisive input parameters or our scenario, have been assessed in [19].…”

“…Originally limited to the power sector, it has been continuously enhanced to also include electric mobility [16], the heating sector [17], as well as hydrogen production, storage, and consumption [18]. For the case study presented here, it has been further enhanced to include the gas sector [19]. The model is designed to optimise capacities and hourly operation of all technologies in a multi-node approach and with perfect foresight over one year.…”

“…These technologies are limited in their use by the sum of exogenously given and, if applicable, endogenously added capacities. The mathematical framework of the model has been documented in [15][16][17][18][19], Figure 2 provides an overview of the framework.

In which way, and in which sectors, will renewable energy be integrated in the German Energy System by 2030, 2040, and 2050? How can the resulting energy system be characterised following a −95% greenhouse gas emission reduction scenario? Which role will hydrogen play? To address these research questions, techno-economic energy system modelling was performed. Evaluation of the resulting operation of energy technologies was carried out from a system and a business point of view. Special consideration of gas technologies, such as hydrogen production, transport, and storage, was taken as a large-scale and long-term energy storage option and key enabler for the decarbonisation of the non-electric sectors. The broad set of results gives insight into the entangled interactions of the future energy technology portfolio and its operation within a coupled energy system. Amongst other energy demands, CO2 emissions, hydrogen production, and future power plant capacities are presented. One main conclusion is that integrating the first elements of a large-scale hydrogen infrastructure into the German energy system, already, by 2030 is necessary for ensuring the supply of upscaling demands across all sectors. Within the regulatory regime of 2020, it seems that this decision may come too late, which jeopardises the achievement of transition targets within the horizon 2050.

In addition to the long‐term goal of mitigating climate change, the current geopolitical upheavals heighten the urgency to transform Europe's energy system. This involves expanding renewable energies while managing intermittent electricity generation. Hydrogen is a promising solution to balance generation and demand, simultaneously decarbonizing complex applications. To model the energy system's transformation, the project TransHyDE‐Sys, funded by the German Federal Ministry of Education and Research, takes an integrated approach beyond traditional energy system analysis, incorporating a diverse range of more detailed methods and tools. Herein, TransHyDE‐Sys is situated within the recent policy discussion. It addresses the requirements for energy system modeling to gain insights into transforming the European hydrogen and energy infrastructure. It identifies knowledge gaps in the existing literature on hydrogen infrastructure‐oriented energy system modeling and presents the research approach of TransHyDE‐Sys. TransHyDE‐Sys analyzes the development of hydrogen and energy infrastructures from “the system” and “the stakeholder” perspectives. The integrated modeling landscape captures temporal and spatial interactions among hydrogen, electricity, and natural gas infrastructure, providing comprehensive insights for systemic infrastructure planning. This allows a more accurate representation of the energy system's dynamics and aids in decision‐making for achieving sustainable and efficient hydrogen network development integration.

With planned hydrogen import terminals and production sites along the North and Baltic Seas, the German coast is likely to become the center of the hydrogen economy. Underground hydrogen storage in the sedimentary reservoirs of the region, particularly in the Bunter Sandstone Formation, could provide the required storage capacity for the future hydrogen economy due to its widespread occurrence and proven sealing system. Herein, the storage capacity is assessed using a probabilistic volume approach and possible reactions between the Bunter Sandstone and hydrogen based on geochemical simulations with PHREEQC are determined. This assessment gives an effective storage capacity of 0.84–4.14 PWh in the saline aquifers of the Bunter Sandstone, of which 0.52–2.57 PWh could be stored onshore. If production from currently operating fields are to cease, additional capacities of between 89.43 and 285.53 TWh could be found in its hydrocarbon fields. Mineralogical reactions are shown to be restricted to redox reactions, which do not affect the formation integrity of siliciclastic reservoirs. As a result, pore storage facilities in the Bunter Sandstone could provide an important storage option for the hydrogen economy, but will require further investigations in the lab and in the field.
