The European Union’s goals for the clean energy transition aim for at least a 55% reduction in greenhouse gas emissions by 2030. To meet these objectives, electricity grids will need to adapt to a context where 50% of electricity production will come from renewable energy sources (RES) of all scales by 2030. The significant rise in solar PV and wind energy as a share of total generation will fundamentally reshape the European power system and substantially increase the demand for new HVAC or HVDC cable connections. These connections will be critical in linking islands and offshore wind parks to the mainland, as well as in facilitating long-distance interconnections between countries.

The CABLEGNOSIS project aims to deliver innovative cable technologies that will play a key role in supporting the EU’s clean energy transition, specifically addressing the 2050 targets. CABLEGNOSIS will focus on the development of advanced insulation and conductor design technologies, high-performance and environmentally friendly cable insulation materials, and aging studies of superconducting cables. Additionally, the project will explore recyclability technologies for power cable materials and introduce AI-based tools for pre-fault condition monitoring, aging analysis, and remote diagnostics.

A comprehensive feasibility assessment framework will also be developed, including detailed analyses on the use of superconducting cables for submarine connections. A specific feasibility study will be conducted for offshore wind parks in the Netherlands and Germany.

The CABLEGNOSIS innovative technologies will be validated in five European countries: Italy, the UK, Greece, Hungary, and Cyprus. A complete deployment plan will be delivered to support the development and operation of efficient, reliable, and environmentally friendly cable systems that will facilitate the energy transition. This plan will also provide a framework for scalability and replicability of the technologies in future projects, with particular emphasis on key interconnections such as the UK-Morocco link, the Cyprus-Israel interconnection, and offshore developments in the Aegean Sea.
