Feedstock & Carbon
More than one road to low-carbon hydrogen.
Hydrogen's climate benefit depends on how it's made. HydrogenXT matches the production pathway to the local resource and measures carbon intensity across the whole chain, with zero as the target.
Start with the facts
Clean at the point of use. Measured across the chain.
A hydrogen fuel cell produces electricity, water and heat, with no tailpipe emissions. That part is straightforward. The carbon intensity of the hydrogen itself depends on the feedstock, the process, the energy used to run it, and what happens to the carbon that's separated out.
So we don't use "zero carbon" as a slogan. We treat carbon intensity as a lifecycle result, measured pathway by pathway, and design each site to drive it toward zero.
Production pathways
Diversified by design.
- 01
Natural gas with carbon capture
Steam methane reforming is the most established way to make hydrogen at scale, with decades of field operation. Our plants are designed to capture the carbon dioxide it produces, for use or durable storage.
- 02
Renewable natural gas blending
Blending renewable natural gas from sources such as landfills and agriculture into the feedstock lowers the carbon intensity of the hydrogen further, site by site.
- 03
Woody biomass
Converting forestry residuals and mill byproducts into hydrogen where the resource is local. Our first biomass effort is in Lewis County, Washington.
Biomass to hydrogen
Lewis County, Washington.
HydrogenXT is the development and commercial partner in the Lewis County Hydrogen Alliance (LCH2), a Washington nonprofit working to turn regional forestry residuals into fuel-grade hydrogen, captured carbon dioxide and dispatchable clean power.
The effort sits within Washington's Bioeconomy Development Opportunity (BDO) Zone in Lewis County, between Seattle and Portland on Interstate 5, in a region with a long forest-products tradition. It's how we're extending HydrogenXT beyond natural gas, alongside alliance partners in forestry and conversion technology.
- ~1,000
- wet tonnes a day of residuals at full build
- ~100 t/day
- hydrogen production design target
- ~50 MW
- Advanced Compute IT load objective, on fuel cells
Design targets, phased from a commercial reference unit to the full campus.
Carbon accounting
Three boundaries we account for.
- 01
Feedstock and production
Upstream emissions, conversion energy and the auxiliary loads that run the plant.
- 02
Carbon management
How much carbon is captured, how it's handled, and where it ultimately goes. Selling captured CO₂ as a product is not the same as permanent storage, and we track the two separately.
- 03
Delivered fuel and power
Lifecycle intensity reported for the kilograms and megawatt-hours customers receive, with clear ownership of environmental attributes.
Carbon-intensity results are pathway- and site-specific and are established through the applicable program methodology. Zero carbon intensity is a design target, not a representation of current operating results.
