ENGREEN
DBHE Platform
Deep Geothermal Heat Infrastructure
What We Do?
- Closed-loop deep geothermal heat systems (DBHE)
- 10–30 MW modular baseload architecture
- Urban and industrial heat integration
- 25-year infrastructure-grade design life
- SPV-based project delivery model
We provide stable, 24/7 heat supply independent of weather, daylight, or fuel markets.
Technology Principle
The ENGREEN DBHE Platform operates as a sealed deep-loop heat exchanger:
Heat is transferred from deep geological formations through a closed circulation system and delivered at industrial-grade temperatures suitable for district heating and high-temperature process applications.
The architecture is modular, scalable, and designed using established deep drilling and oilfield-grade engineering standards.
- No water extraction
- No reinjection
- No reservoir management
- No combustion
- No direct emissions
Infrastructure Logic
ENGREEN projects are structured as infrastructure assets:
This is infrastructure-grade heat generation with predictable cash flow characteristics.
- Long-term Heat Purchase Agreements (HPA)
- Regulated or utility off-takers
- Index-linked revenue models
- 20–25 year operational horizon
- Green Bond compatible financing structure
ESG & Regulatory Alignment
The platform enables:
Closed-loop geothermal heat offers structural fossil fuel displacement without hydrogeological risk.
- Carbon-free heat production
- Measurable CO₂ displacement
- EU Taxonomy alignment (Articles 4.1 / 4.15)
- ETS2-compatible economic positioning
- Audit-ready environmental reporting
Project Development Model
ENGREEN supports projects through:
Technology ownership remains with ENGREEN.
Projects are delivered under structured, performance-aligned agreements.
- Technical platform design
