Chuntoh Ghuna: advancing sustainable energy at scale
The world’s largest hydrothermal liquefaction facility.
Chuntoh Ghuna – leading the global commercialization of HTL technology
Initially converting 25,000 dry tonnes of wood biomass into 50,000 barrels of bio-intermediate annually, Chuntoh Ghuna is permitted to double this capacity. The facility’s footprint allows for potential quadrupled output of 200,000 barrels yearly.
The Chuntoh Ghuna facility establishes Arbios as renewable energy leader and serves as a blueprint for future global opportunities. By proving commercial viability at scale, we’re paving the way for similar facilities in Europe and The Americas, driving worldwide sustainable bio-oil production.
Platform
Cat-HTR™ (Catalytic Hydrothermal Reactor) platform
Initial processing capacity
25,000 dry tonnes of wood biomass per year
Start of operations
2024
Scalability
Potential for four processing lines (200,000 barrels) within the existing footprint
Initial production output
50,000 barrels of sustainable bio-oil per year. Designed to operate 24/7.
In commissioning

Built in partnership with the Lheidli T’enneh Nation
The Chuntoh Ghuna facility, whose name means “the forest lives” in the Dakelh language, was developed in close partnership with the Lheidli T’enneh First Nation on whose unceeded territory it stands. This relationship began with a joint environmental due diligence to ensure alignment with the Nation’s cultural and environmental values.
We thank the Lheidli T’enneh for this opportunity and for setting a new standard for responsible industrial development, demonstrating how businesses and Indigenous communities can work together to create sustainable economic opportunities.

Our air emissions have been reviewed and approved.
The facility in Prince George has received a Discharge Permit for the facility under Environmental Management Act issued by the British Columbia Ministry of Environment and Climate Change Strategy. With an Environmental Management Plan, the facility is not expected to adversely affect air quality.
