How the system works,
and why ethanol.

A patented oxidative-reforming process converts ethanol into clean hydrogen and valuable co-products in a non-combustion reaction that avoids the cost, complexity, and emissions of conventional hydrogen delivery.

How the system works

Ethanol in, clean hydrogen out, via a catalytic reaction with no flame.

The process, step by step
  • Liquid feedstock delivery

    Ethanol, an energy-dense hydrogen carrier, is delivered and stored using vast existing U.S. infrastructure.

  • Controlled oxidative reforming

    Inside PCCH2's reactor, ethanol is converted into a hydrogen-rich stream through catalytic oxidative reforming, featuring the patented PyroCat™ catalyst, validated over thousands of hours of extreme-condition laboratory testing proven to prevent catalyst degradation.

  • Separation & conditioning

    Water-gas shift reactors convert the remaining carbon monoxide into additional hydrogen, and a pressure swing adsorption (PSA) unit purifies and conditions the stream to meet the specification each application requires.

  • Co-product capture

    Pure biogenic CO₂, nitrogen, and water are captured for reuse, enabling a low carbon index (negative if process biogenic CO₂ is sequestered).

Why ethanol as a hydrogen carrier

We don't burn ethanol. We reform it.

Our process converts ethanol into hydrogen through oxidative reforming, a chemical reaction inside a non-combustion reactor using PCC's patented catalyst.

Ethanol logistics in morning light: three black rail tank cars marked ETHANOL standing on a through siding, a loading arm lowered onto the dome of the nearest car with a safety cage over the working position and a grounding cable clamped to the car, an elevated walkway along the train, and an ethanol storage tank on its containment base with the processing plant beyond
Ethanol logistics

The carrier

We don’t move hydrogen. We move the carrier.

Ethanol is a stable, locally produced liquid that already travels at scale, cheaply. Hydrogen doesn’t. So we ship the carrier and convert it on site, capturing pure biogenic CO₂, nitrogen, and water as valuable co-products.

Why ethanol works
  • Existing infrastructure

    Ethanol moves today through established rail, truck, and terminal networks, reducing the need for new hydrogen pipelines or specialized long-haul delivery.

  • A small footprint on the market

    A facility’s ethanol draw is a very small share of the ~16-billion-gallon U.S. market.

  • On-site conversion

    Energy is delivered in liquid form and converted into hydrogen on site, at the point of use: no hydrogen delivery network to build.

  • Biogenic carbon

    Ethanol is made from crops that absorb CO₂ as they grow. The carbon is biogenic, part of the current carbon cycle, not fossil carbon from legacy hydrocarbon sources.

Published research

Independent lifecycle analysis

PCC Hydrogen's lifecycle carbon-intensity study, co-authored with the National Laboratory of the Rockies (NLR, the National Renewable Energy Laboratory at the time of publication) and published in the peer-reviewed journal Biofuels, Bioproducts and Biorefining (opens in a new tab) in March 2025, supports a process with low or even negative carbon intensity and no NOx or particulate-matter emissions.

  • Deeper CI reductions

    Carbon intensity starts with the feedstock: low-CI ethanol lowers the hydrogen’s CI further. Adding carbon capture pushes CI below key thresholds, while the remaining pure biogenic CO₂ is sold into food & beverage and e-fuel markets rather than emitted.

  • Land use, in context

    PCC draws on ethanol already produced at scale, roughly 16 billion gallons a year in the U.S. alone. A facility’s draw is a rounding error on that market: existing ethanol redirected to a higher-value clean-energy use, not new production.

  • Fossil CO₂ substitution

    In markets like the U.K., biogenic CO₂ from the process can directly substitute fossil-derived CO₂ in industrial supply chains, an additional decarbonization benefit beyond the hydrogen itself and a valuable revenue stream.
