Why renewable gas

A renewable replacement for fossil gas.

Industrial heat is one of the hardest energy uses to decarbonise. Kilns, boilers and dryers are built around gas, LPG, oil or coal, and electricity is rarely a like-for-like substitute.

A CNP plant converts locally sourced wood and residues into renewable gas. It can be fired directly in process equipment, used to raise steam, or upgraded to synthetic natural gas that meets pipeline specifications and is injected into the local gas network.

Fuel store and gasification plant
  • Renewable heat and steam for kilns, boilers and dryers
  • Pipeline-quality synthetic natural gas for grid injection
  • Fuel sourced locally, near the plant
  • Delivered under a long-term supply agreement

The pathway

From biomass to pipeline-quality renewable gas.

Heat and steam can be taken from the cleaned syngas; for the gas grid it continues through methanation and conditioning.

Applications

Two outputs, one plant.

  • Heat and steam

    Renewable gas fired directly in process equipment, or used to raise steam for the site.

  • Synthetic natural gas

    Upgraded to pipeline quality and injected into the local gas network.

  • Local fuel

    Locally sourced wood and forestry or agricultural residues.

  • Fuel substitution

    Replaces LPG, oil, coal or fossil gas without replacing the equipment that uses it.

  • Supply agreement

    Buy the gas, heat or steam. CNP builds, owns and operates the plant.

  • Carbon removal

    Where the configuration allows, stable biochar is recovered alongside the gas.

  • Modular

    Factory-built modules sized to the heat load or gas offtake.

Locally sourced wood to pipeline-quality synthetic natural gas

The challenge
A regional wood resource with no high-value outlet, and a local gas network that needs renewable supply.
What CNP delivers
A CNP plant converting locally sourced wood into synthetic natural gas that is piped into the local gas grid.

FAQ

Common questions.

What is synthetic natural gas?

Gas made from biomass and upgraded until it meets pipeline specifications, so it can be used anywhere natural gas is used and injected into the gas grid.

Can renewable gas replace the fuel in our kilns?

In many thermal processes, yes. We assess your equipment and process requirements during the site assessment.

What feedstock does it use?

Locally sourced wood and agricultural or forestry residues.

Do we need to fund the plant?

No. Under a supply agreement CNP finances, builds, owns and operates the plant, and you buy the gas, heat or steam.
