Heat & Electricity for Communities

A smooth transition from coal to renewable energy, powered by torrefied pellets

View biocoal solution

Power generation

Designed as a drop-in solution, biocoal can be co-fired with coal and gradually scaled up to 100%, enabling a smooth transition to renewable energy using existing plant infrastructure.

Its consistent quality and high energy density ensure reliable baseload and peak-load heat supply for communities.

District heating

Heat supply for urban networks must depend on reliable, cost-effective solutions that can integrate smoothly with existing infrastructure. Biocoal offers a practical route to renewable district heating, with the potential to replace up to 100% of fossil fuels.

Its consistent quality and high energy density ensure stable and continuous heat supply while achieving decarbonization without performance trade-offs.

Why utilities & district heating operators choose biocoal

Higher Efficiency, Lower Complexity:

The Torrefied Advantage​.

  • Low CAPEX
  • Integrate with existing processes
  • Easy to grind
  • Weather resistant
  • No storage needed (can be stored outside like coal)
  • High energy density ( ≥ 18.5 MJ/KG)
  • Co-firing ratio up to 100%
  • Safe to transport worldwide
  • Non-hazardous, no self-heating
  • Dust-free
  • No carbon-monoxide emission
  • Safe for employees
