Green investment subsidy

What does the GREEN investment subsidy entail?

The subsidy targets companies that invest in:

  • transitioning from fossil fuels (such as heating oil, natural gas and diesel) to electric power or green energy (such as biogas and green or blue hydrogen) (Greening Theme)
  • reducing their overall energy consumption (Energy Efficiency Theme).

The following investments are not eligible:

  • investments in technologies included in the Limitative Technology List (LTL) of the ecology premium+ subsidy. These investments must be submitted through ecology premium+. However, you may split projects or investments to submit the different parts through different subsidy instruments;
  • investments to meet legal requirements (e.g. related to standards to be met, environmental permits, energy policy agreements and sector federation agreements, etc.). Investments must clearly go beyond what is required by law.

Greening theme - switching to green energy or electricity

‘Greening’ refers to an end user replacing fossil fuels (such as natural gas, diesel, heating oil, etc.) with the use of green heat, green cooling, electric power, green hydrogen, blue hydrogen or residual heat or cold.

Green energy carriers subsidized in this call are:

  • Heat, coming from:
    • Renewable energy sources.
      Renewable energy sources that can be supported by GREEN investment subsidy include: solar thermal energy (other than PV or solar photovoltaic panels), geothermal, ambient (excluding air-powered heat pumps), tidal, wave and other ocean energy, hydropower, biomass meeting the sustainability criteria of RED II, gas from sewage treatment plants and biogas.
    • Green hydrogen: produced from green electricity
    • Blue hydrogen: hydrogen produced from fossil fuels with carbon separation (carbon capture) and permanent storage (carbon storage) or use of the captured carbon emissions (carbon utilisation).
    • Residual heat
  • Electrification (example: making a natural gas-powered process electric)

! Attention - not eligible:

  • solid or liquid biomass that does not meet RED II sustainability criteria
  • ambient air (example: air-powered heat pump)
  • landfill gas
  • PV panels, wind turbines, or other ways to produce electricity

Energy Efficiency Theme

The first step toward more sustainable use of energy is to use less energy. If energy is used more efficiently for your core activities, you can also receive subsidy (e.g., through adjustments to the production process, thermal storage, etc.). Core activities are activities that are primarily production-related.

What does not qualify?

  • The technology in which will be invested must exceed standard technology. Standard investments such as thermal insulation, more efficient lighting, speed control of compressors, building management systems, making the vehicle fleet more sustainable, solar panel control etc. are not eligible for subsidy. 
  • Investments only related to the building, vehicle fleet, etc. are not eligible.  
  • Investment in new fossil technologies is not eligible unless it is about upgrading residual heat.
