carbonauten energy

Renewable, base load capable and cheap from 40 € per MWh thermal

Up to 1,250° C for process, district, local heating or electricity (CHP)

The decentralized “minus CO2 factories” provide cheap and CO2-neutral energy 24/7 for companies, municipalities, cities and communities. The carbonauten technology generates significantly more energy from the woody biomass residues than is required for their carbonization. The modularly expandable plants generate at least 24 GWh of heat, 10 GWh of electricity or 120 – 1,000* t of green hydrogen, or mixed forms thereof, per year. The energy is provided through a contracting model.

Energy concept

carbonauten offers permanent, cheap and CO2-neutral energy for industry, cities and communities. For energy contracting, carbonauten finances, builds and operates minus CO2 factories and feeds the excess energy – thermal and/or electrical – into the existing processes, heat and electricity grids, or provides green hydrogen.


Forms of energy

  • Thermal energy as directly usable process heat
  • Electrical energy by converting synthesis gas to electricity
  • Green hydrogen via electrolysis and as a by-product of activated carbon production

Our range

  • Base-load capable, renewable energy
  • Usage of waste materials
  • Independent from the input material
  • Direct feed into heating networks
  • Local electricity production

Synthesis gas

  • In ovens with up to 1.250°C
  • Direct electricity generation through CHP units
  • Generation of steam

Cheap thermal energy

  • Direct process heat of up to 850°C
  • Residual heat from carbonization

Performance data of
20 modules

A minus CO2 factory with 20 modules supplies at least 32,000 t of biocarbon, 160 GWhheat, 100,000 t CO2 certificates, 1,600,000 l pyrolisis oil, and 100.000 t of NET Materials®. Considering the generated thermal energy alone, a paper factory could be supplied with CO2-neutral energy from the synthesis gas.

Biocokes from problematic materials.

Some problematic inputs can easily be carbonized. However, they should not be released back into the environment even in the form of char. This includes chemically contaminated damaged wood or old railway sleepers. From this material, we can produce Biocokes, which are burned in blast furnaces and thus replace brown and black coal.
