Investment aid for renewable energy, renewable hydrogen and high-efficiency cogeneration
Do you want to request financial aid for renewable energy, hydrogen or cogeneration investments?
Under the Law of 8 December 2025 on Luxembourg's environmental and climate protection aid scheme, the Ministry of the Economy offers investment aid to businesses that promote the production of energy from renewable sources, the production of renewable hydrogen and high-efficiency cogeneration.
This aid covers four types of investment:
- Renewable energy production — solar, wind, biomass, biogas, heat pumps and other renewable sources, including associated storage solutions
- Renewable hydrogen production — installations producing exclusively renewable hydrogen, including dedicated transport and distribution infrastructure
- High-efficiency cogeneration — units achieving primary energy savings of at least 20% compared to separate heat and electricity production
- Energy storage — electricity, thermal or biogas storage directly connected to a renewable energy production installation, subject to specific conditions
The eligible costs are the total investment costs — a more favourable basis than most other measures under the Environmental Law, where only additional costs are eligible.
We can advise you on:
- whether your company and project meet the eligibility criteria
- which application procedure applies to your situation
- how to structure your application and submit it via MyGuichet.lu
Maximum amount of financial aid
The amount of aid is calculated on the basis of total investment costs and cannot exceed the following thresholds:
| Small company | Medium company | Large company | |
| Renewable energy production | 65 % | 55 % | 45 % |
| Storage or transport | 50 % | 40 % | 30 % |
Important: When aid is granted through a competitive tendering procedure, the aid intensity may reach up to 100% of eligible costs — with no cap on the aid rate.
Important: The application must be submitted before the start of works or the first binding order of equipment.

Key benefits
Benefit from the following advantages:
-
Total investment costs are eligible
Unlike most other measures under the Environmental Law, this aid covers total investment costs rather than only the additional environmental premium, making it particularly attractive for large-scale renewable energy projects. -
A broad scope of eligible technologies
Solar, wind, biomass, biogas, heat pumps, renewable hydrogen and high-efficiency cogeneration are all covered, giving businesses flexibility to choose the technology best suited to their operations. -
Expert support throughout the processLuxinnovation helps you assess your eligibility, identify the right application procedure and submit your application via MyGuichet.lu, reducing complexity and maximising your chances of success.
Who can benefit?
This aid is open to all companies legally established in Luxembourg that hold a valid business permit and are investing in the production of energy from renewable sources, renewable hydrogen or high-efficiency cogeneration.
Key eligibility conditions include:
- Storage investments are only eligible when combined with a renewable energy production installation (at least 75% of stored energy must come from the directly connected production installation, on an annual basis)
- Renewable hydrogen installations must produce exclusively renewable hydrogen; the electrolyser capacity must not exceed the combined capacity of the connected renewable energy production units
- High-efficiency cogeneration units must achieve primary energy savings of at least 20% compared to separate heat and electricity production
- Biogas and biomass installations must comply with the sustainability criteria of EU Directive 2018/2001
- Natural gas cogeneration installations are only eligible through a competitive tendering procedure
Applications must be submitted online via MyGuichet.lu before any binding commitment is made.
This financial support measure is provided by the Ministry of the Economy.
