PROJECT: ERD Reinswald

Project Summary:

• Year: 2021

• Client: Energiegenossenschaft Reinswald-Durnholz

• Labels: Consulting, long term storage

Study on the use of hydrogen in the Reinswald ski area, long-term storage of surplus electricity in the form of hydrogen.

Project Description

The “ERD-Hydrogen Study,” commissioned by the Reinswald-Durnholz Energy Cooperative (ERD), evaluates hydrogen production as a solution for balancing seasonal energy demands in the Sarntal region. Utilizing surplus hydroelectric power from three power plants, the study explores hydrogen production through electrolysis, with hydrogen being stored for later use. This solution aims to stabilize energy supply by converting surplus electricity into hydrogen, which can be reconverted into electricity during high-demand periods. The study investigates technical feasibility, energy efficiency, and potential economic benefits for ERD members, emphasizing self-sufficiency and sustainability in energy management.

Results

The study confirms the technical feasibility of using hydrogen to stabilize energy supply in the ERD network. Surplus electricity can be stored efficiently as hydrogen, mitigating seasonal fluctuations. The analysis shows that hydrogen can lower external energy dependencies, with potential economic gains by reducing energy costs and offering hydrogen as fuel. CO₂ savings enhance environmental impact. Integration into the existing infrastructure and stakeholder engagement were highlighted for successful implementation.
