The District Heating Pozo Fondón is an existing network that supplies heat generated from geothermal energy (mine water) and biomass to surrounding buildings, already operating on the former mine site and recently recognized by the International Energy Agency with a Global District Energy Climate Award.[1] The Mine‑to‑H2 project plans to integrate the waste heat from electrolysis into this district heating system, maximizing energy efficiency and reinforcing the site’s role as a multi‑energy hub.[1]

As part of Mine‑to‑H2, ALSA plans to introduce two new interurban bus models that use green hydrogen produced at Pozo Fondón: one equipped with a fuel cell powertrain and the other using hydrogen in direct combustion engines.[1] These buses will operate on routes in the central Asturian area to demonstrate the decarbonization of regional road transport using locally produced renewable hydrogen.[1][7]

The project includes a photovoltaic plant installed on land from a former HUNOSA open‑pit coal mine in the area of Mieres–Langreo, providing part of the renewable electricity needed for hydrogen production at Pozo Fondón.[1] This PV installation is a key pillar for ensuring that the hydrogen qualifies as green by being produced with renewable power and exemplifies the reuse of degraded mining land for solar energy.
