Cortus Energy’s Business Mission is to: Provide cost effective renewable energy gas solutions for power, industrial and transport applications that are based upon the patented WoodRoll® technology.

The intention of Cortus Energy is to Build Own & Operate (BOO) the WoodRoll® installations from which generated energy products (syngas, power, SNG, hydrogen etc.) are sold on basis of long term supply agreements. However Cortus Energy is open to supply turnkey ready WoodRoll® installations and in the future to sell WoodRoll® on licensee basis.

The advantages of WoodRoll® are several:

  • It is a renewable energy solution which can replace fossil fuels in applications which has not been open to renewable solutions before (due to technical demands)
  • Fuel flexibility paired with the highest efficiency and a clean gas are fundaments to establish a profitable business case over the installation’s full life time
  • Produce a tar free gas which means the single largest cause (the tars) for low efficiency and availability is eliminated.
  • The gas is energy rich gas with a favorable composition to be further processed into other energy products such as: SNG, hydrogen and liquid biofuels.
  • The concept can be used for multiple applications, it is scalable and repeatable.
