A recent analysis prepared for the European Commission reveals that the EU's energy infrastructure investment needs are projected to soar, surpassing €2 trillion from 2024 to 2040. The bulk of this investment will be directed towards electricity infrastructure, particularly in electricity distribution, amounting to €730 billion, driven by the transition to renewable energy and electrification. Transmission infrastructure will also see significant investments of over €472 billion, with a focus on national transmission networks and cross-border connections. Notably, hydrogen infrastructure is set to receive nearly €170 billion in investments, with a majority allocated to hydrogen pipelines and the rest to storage, import terminals, and electrolysers. Despite this, carbon capture and storage have the lowest investment needs within the infrastructure categories. The analysis indicates that investment requirements will peak around 2027 to 2029, with an unequal distribution across the EU, favoring north-western Europe for distribution investments and central-western Europe for transmission investments. Germany, France, and the Netherlands are expected to account for more than half of the total investments up to 2040. Furthermore, the financing of these projects will rely on both public and private funding, with EU financial support playing a crucial role in de-risking high-cost ventures, especially in newer technologies and cross-border initiatives. Various mechanisms, including grants, loans, and guarantees, will be employed to support different types of infrastructure and country conditions. The analysis underscores the importance of EU financial aid in ensuring affordable grid access and limiting cost burdens on consumers, particularly in the context of rising investments in TSOs and DSOs. In conclusion, the analysis sheds light on the immense investment opportunities and challenges in decarbonizing the European energy infrastructure, emphasizing the pivotal role of both public and private financing, with EU support playing a key role in driving the transition towards a decarbonized economy.
