Project overview and goals

The project named RegHYnu involves the production of green hydrogen from a floating photovoltaic power plant that could be installed on the Codole dam in the Reginu valley. The initiative aims to locally produce renewable energy, store it in the form of hydrogen, and transport it to various consumption sites, notably to power the trains of the Corsican Railways.

Public support and evolving perception

The project, while not new, has been given a new dimension by Acquasole through a citizen petition launched after years of efforts with elected officials and decision-makers. The petition has exceeded 1,000 signatures, with about a dozen to fifteen new signatures per day, indicating growing public support.

Strategic location and environmental benefits

Bertrand Ciavaldini, a hydrogen specialist, notes that the Codole dam is a strategic location due to its shallow depth, exposure to sun and wind, and issues with evaporation and cyanobacteria. Floating photovoltaic panels could significantly limit these phenomena.

Energy production and infrastructure advantages

The project plans to cover about 30 hectares of the 80-hectare reservoir, with an estimated annual electricity production of 42 GWh. Acquasole projects that the installation could save nearly a million cubic meters of water per year, equivalent to raising the dam by nearly a meter, though these estimates require hydrological and environmental studies for confirmation.

Proximity to infrastructure and energy strategy

Proximity to existing infrastructure, including power lines and the railway, is highlighted as an advantage for deploying the project on a larger scale. The Reginu station could host a hydrogen production unit, with the railway facilitating transport to various consumption points.

Energy needs and cost savings

The association warns that Corsica's electricity needs could significantly increase due to electric mobility, demographic growth, and new uses, exacerbating an already strained energy system. One of the main applications envisioned is the modernization of Corsican Railways through hydrogen-powered trains, which could reduce operating costs by 30% compared to diesel and 50% compared to conventional electrical solutions.

Economic and employment potential

The project could generate up to 200 direct jobs, with opportunities for students from the University of Corsica and Paoli Tech. Local teams could be formed for the conversion and maintenance of railway equipment, with skills potentially expanded to other hydrogen-powered equipment on the island.

Global examples and planned discussions

Ciavaldini highlights that several countries have already implemented hydrogen train projects, indicating the technology's maturity. The initiative also includes a planned meeting on November 12 to discuss the project and its broader implications, including the development of a movement dedicated to frugal and creative architecture.

Feasibility and public influence

While the project's feasibility, environmental impact, and technical aspects remain to be resolved, the association emphasizes the need for public opinion to influence political decisions. The figures mentioned in terms of employment, water savings, and operating costs are projections from the project promoters.
