“…In addition, certain annual factors (e.g., the period of technology and interest rate) were required to calculate the final total yearly cost. As for the investment cost, the costs of different conventional and renewable electricity generation technologies were taken from research findings [ [50] , [51] , [52] ]. These cost data have been widely used in numerous studies at the EU level and were considered suitable for conducting economic analysis in this study.…”

“…Finally, the last component integrates the compiled spatial data and offshore nodes in the IESA-NS energy system model, The IESA-NS model, described in detail in [12] , permits to include a tailor made offshore representation, thus allowing us to directly implement the findings and results from the data clustering step.…”

“…Another trend that has been analysed in the literature is the role that hydrogen can play in the NSOG development. Previous studies indicate that large amounts of hydrogen might be relevant in order to decarbonise the NSR (up to 7.3 EJ in [12] ). The production of part of this hydrogen offshore has recently emerged as an attractive alternative.…”

“…2) in scenarios with high penetration of offshore wind in the NSR, there is a considerable amount of curtailment during some periods of high wind availability (e.g. in [12] it is cost-effective to curtail 30 TWh of offshore wind in 2050). Offshore electrolysers might provide enough flexible capacity in order to integrate this curtailed energy.…”

“…Considering the aforementioned knowledge gaps, this paper aims to provide new insights on both the NSOG optimal design and the offshore hydrogen production. The main contributions are threefold: (1) We analyze the benefits of an NSOG design in the NSR in 2050, using an enhanced version of the IESA-NS optimization energy system model [12] . For this analysis, we model different scenarios in which all the sectors of the energy system are included.…”

The North Sea Offshore Grid concept has been envisioned as a promising alternative to: 1) ease the integration of offshore wind and onshore energy systems, and 2) increase the cross-border capacity between the North Sea region countries at low cost. In this paper we explore the techno-economic benefits of the North Sea Offshore Grid using two case studies: a power-based offshore grid, where only investments in power assets are allowed (i.e. offshore wind, HVDC/HVAC interconnectors); and a power-and-hydrogen offshore grid, where investments in offshore hydrogen assets are also permitted (i.e. offshore electrolysers, new hydrogen pipelines and retrofitted natural gas pipelines). We compare these scenario results with a business as usual scenario, in which offshore wind is connected radially to the shore and no offshore grid is deployed. All scenarios are run with the IESA-NS model, without any specific technology ban and under open optimization. This paper also presents a novel methodology, combining Geographic Information Systems and Energy System Models, to cluster offshore spatial data and define meaningful offshore regions and offshore hub locations. This novel methodology is applied to the North Sea region to define nine offshore clusters taking into account offshore spatial claims, and identifying suitable areas for single-use and multi-use of space for renewable energy purposes. The scenario results show that the deployment of an offshore grid provides relevant cost savings, ranging from 1% to 4.1% of relative cost decrease (2.3 bn € to 8.7 bn €) in the power-based, and ranging from 2.8% to 7% of relative cost decrease (6 bn € to 14.9 bn €) in the power-and-hydrogen based. In the most extreme scenario (H2) an offshore grid permits to integrate 283 GW of HVDC connected offshore wind and 196 GW of HVDC meshed interconnectors. Even in the most conservative scenario (P1) the offshore grid integrates 59 GW of HVDC connected offshore wind capacity and 92 GW of HVDC meshed interconnectors. When allowed, the deployment of offshore electrolysis is considerable, ranging from 61 GW to 96 GW, with capacity factors of around 30%. Finally, we also find that, when imported hydrogen is available at 2 €/kg (including production and transport costs), large investments in an offshore grid are not optimal anymore. In contrast, at import costs over 4 €/kg imported hydrogen is not competitive.

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.
