The Clean energy for EU islands secretariat has released two new technical-assistance reports, published in July, furthering its mission to help island communities across the EU accelerate their transition to 100% renewable energy by 2030. These reports form part of the Secretariat’s ongoing “30 for 2030” programme, which delivers targeted technical assistance to islands aiming to achieve full decarbonisation within the decade
The first study focuses on the Municipality of Cres, Croatia, and examines the feasibility of introducing a fleet of hydrogen-powered vehicles for road transport. Drawing on a detailed assessment of technical, economic, environmental, and operational factors, the report presents a tailored set of recommendations to support the shift towards clean mobility. Such a move could significantly reduce greenhouse gas emissions, improve air quality, and establish Cres as a pioneer of sustainable transport in an island setting.
The second study turns to Lesvos, Greece, where the Secretariat has explored the potential for developing geothermal energy.. With its existing mix of wind farms, photovoltaic systems, and diesel-fired thermal generation, Lesvos stands to benefit from integrating geothermal resources, which could diversify its energy supply and reduce reliance on imported fossil fuels.
The findings of these studies are expected to guide local authorities and transition teams in shaping concrete implementation steps, which may include pilot projects, stakeholder engagement initiatives, and the pursuit of funding to bring hydrogen mobility and geothermal energy into operation. The experience gained on Cres and Lesvos could serve as a blueprint for other EU islands embarking on similar decarbonisation journeys.
By publishing these reports, the Clean Energy for EU Islands Secretariat highlights its multi-pronged approach to clean energy transition and reinforces its role as a catalyst for change—helping island communities turn technical potential into tangible action, and ensuring that Europe’s islands are at the forefront of the clean energy transition.
