A new report highlights how coordinated, multi-vector infrastructure development across electricity, hydrogen, and CO₂ networks could significantly cut costs and optimise investments, provided that EU-level governance and cross-border cost-sharing are strengthened.
According to the original report prepared for Agora Energiewende, shifting to integrated, co‑optimised infrastructure planning across electricity, hydrogen, fossil gas and CO₂ networks could reduce Europe’s energy system costs by more than €560 billion between 2030 and 2050 , rising to about €750 billion when avoided back‑up generation is included. The modelling underpinning the finding was developed by Fraunhofer IEG and Fraunhofer ISI with consultancy d‑fine and quantifies efficiencies that fragmented, sector‑by‑sector planning commonly misses.
The analysis uses a 62‑region, multi‑vector optimisation to capture interactions between renewable siting, grid expansion, storage, and industrial hydrogen demand. According to the report, an integrated approach would require around 505 GW less backup capacity, about 15% less onshore wind capacity and some 9% fewer electrolysers than scenarios built from isolated national or sectoral assumptions. Those differences translate into lower technology and infrastructure CAPEX and a materially different investment timetable.
A clear policy implication is that electricity transmission remains the dominant infrastructure priority through to 2050: the model shows significant grid expansion is needed to support electrification of transport, heating and industrial processes. By contrast, widespread continental hydrogen or CO₂ trunk networks are not supported in the integrated scenarios; the study finds hydrogen pipeline proposals currently on the table exceed modelled needs by roughly 2.5 times and are better targeted at specific industrial clusters.
The report also highlights governance shortfalls. National plans and the existing Ten‑Year Network Development Plan rely on largely bottom‑up inputs and sector‑specific modelling that are not consistently cross‑checked. According to the authors, this institutional fragmentation prevents benchmarking against a Europe‑wide optimum and risks locking in suboptimal, costly infrastructure choices. The study therefore recommends an independent, open‑source co‑optimisation capability at EU level , options include the European Commission, the Joint Research Centre, or a newly constituted independent system operator , to produce a high‑level system vision that can guide national network development plans.
Investment allocation and cost‑sharing are practical priorities. The modelling can identify cross‑border corridors that generate shared market benefits, but current cost‑allocation mechanisms are inadequate to compensate countries bearing disproportionate investment burdens. Without revised frameworks for cross‑border cost sharing and congestion income distribution, the report warns, strategically important projects may be delayed or underbuilt, undermining security of supply and affordability.
For industrial decarbonisation stakeholders, the takeaway is twofold: first, integrated planning materially alters the scale and timing of required assets , particularly shifting emphasis toward grids and targeted hydrogen infrastructure , and second, realising those efficiencies depends on stronger EU‑level modelling and governance to align national plans and mobilise shared financing. Industry participants and system operators should therefore engage with emerging co‑optimisation exercises and cost‑sharing discussions to ensure project pipelines reflect system‑level priorities rather than fragmented national targets.

It focuses on energy infrastructures, including electricity, gas (natural gas and future hydrogen infrastructures), CO₂ from carbon capture, transport, storage, and use, and heat infrastructure contributing to sector coupling. The study aims to develop an integrated infrastructure planning procedure in Europe that considers different energy vectors and their dynamic interaction across the EU, resulting in an overall optimisation based on common framework conditions across all Member States and energy vectors.

The analysis reveals that optimised grid planning could save Europe’s energy system over €560 billion between 2030 and 2050. When considering the savings from avoiding reserve power plants, the amount rises to €750 billion. This integrated approach directs investments to where they bring the greatest benefit and highlights the synergies between electricity, hydrogen, gas, and CO₂.

These energy system models are linked to macro-economic models that illustrate the economic effects of the energy transition. All models cover at least the individual countries of the European Union and the timeframe until 2050. They are based on a uniform and coordinated framework, supported by extensive databases of statistical and empirical data, as well as detailed technology data from practice, ensuring the validity of the results.

These models provide a foundation to make decisions about the political framework and economic investments that will shape our energy system for decades. The models use extensive databases of relevant statistics, maps, technology profiles, and consumption and generation curves. To achieve comparable and transparent results across regions, countries, and continents over periods up to 2050, the models exploit coordinated framework conditions, as well as open source and open data concepts.
