Best suited for
SMEs and large enterprises based in Hungary (excluded Budapest).
Industries based in Hungary (excluded Budapest).
Brief Description
This national scheme supports projects that aim to reduce the financial risk of geothermal drilling in Hungary (excluding Budapest). Funding covers the drilling, completion, and testing of the first geothermal well, as well as related project preparation and technical activities. The scheme is designed to address one of the main barriers to geothermal development: uncertainty about subsurface resources. The aid is provided as a non-repayable grant. Projects must be physically completed within 24 months of signing the grant agreement. Support intensity depends on whether the geothermal well is successfully certified at the end of the project, with higher support rates applied when drilling risks materialise.
Thematic focus
- Deep geothermal energy
- Geothermal exploration and drilling
- Risk reduction for geothermal investments
- First-well development and testing
USE THIS WHEN
You are developing a deep geothermal project in Hungary and need public support to reduce the financial risk of drilling and testing the first well. This scheme is particularly relevant at the early investment stage, before large-scale geothermal deployment decisions are taken.
