Life SustainHuts

The LIFE SUSTAINHUTS project, which can be translated as Sustainable Huts, aims to modernize and optimize from the energy point of view nine mountain huts from four European countries (Spain, Italy, Romania and Slovenia), with the target of reducing their pollutant emissions.

The energy modernization will consist in the optimization of the energy management in the mountain hut, improvement of the insulation, and installation of renewable energies based technologies, including the inclusion of a complete system of production, storage and use of renewable hydrogen in one of the Aragonese huts, in Bachimaña. The implementation of these improvements aims to achieve an improvement in energy efficiency by 20%, a reduction of CO2 emissions in 21 tonnes per year per hut and NOx (nitrogen oxides) in 0.5 tonnes per year and hut, as well as reducing the number of helicopter trips required to supply the fuel, with an estimated saving of one tonne per year of kerosene per establishment.

As result of the project, a series of methodological guides to replicate the solutions developed in the huts will be elaborated, so that the environmental improvements achieved can be replicated in the future to other locations, both in Europe and around the world.

The project has a duration of 4 years and it will be developed by a consortium integrated by the following members: Foundation for the Development of New Hydrogen Technologies in Aragon (coordinator), Aragonese Mountaineering Federation, Italian Alpine Club Turin section (Italy), Environmental Park (Italy), Slovenia Mountain Partnership, Slovenia’s Hydrogen Technology Center, Ljubljana University (Slovenia), and the University of Brasov (Romania).


  • Creation of a resource assessment campaign adapted to extreme mountain conditions.
  • Design and simulation of renewable installations considering different mountain environments.
  • Design of a complete hydrogen cycle production based on renewable energy (production by electrolysis of water, pressurized storage, and power production by fuel cell).
  • Reduction of the dependence from fossils fuels (diesel).
  • Selection and installation of new generation insulation materials.
  • Implementation and demonstration tasks at 9 demo huts classified by altitude: 1 demo-hut at low altitude (<1.000 m), 4 demo-huts at medium altitude (1.000 m – 2.000 m), 3 demo-huts at high altitude (2.000 m – 3.000 m), and 1 demo-hut at extremely high altitude (>3.000 m).
  • Life Cycle Assessment analysis aiming to determine environmental impacts of the new implemented technologies compared to present status.
  • Extrapolation of results to other mountain areas.
  • To look for a high project impact at national and international scope.

Expected Results

The aim is to achieve a 20% improvement in energy efficiency, a reduction of CO2 (carbon dioxide) emissions by 21 tonnes per year per hut and NOx (nitrogen oxides) by 0.5 tonnes per year and hut, as well as reducing the number of helicopter trips made to them to supply the current fuel, with an estimated saving of one tonne per year of kerosene per establishment.
