Delivering the highest process efficiency and lowest LCOH commercially available

Experience the pinnacle of hydrogen production with our proven LCH™ technology: a ready-now solution delivering high-purity, clean hydrogen at scale. Unleashing the power of Gas Heated Reforming (GHR) and Autothermal Reforming (ATR), our process excels by capturing up to 99% of CO₂ produced during hydrogen generation. Compared to conventional steam methane reforming (SMR) technologies, our LCH process ensures superior efficiency and cost-effectiveness, significantly reducing both plant CAPEX and OPEX requirements.

Efficiency is key
Our CCS-enabled LCH technology prioritizes process efficiency, maximizing feedstock utilization to elevate your hydrogen production capabilities. The levelised cost of hydrogen, reflecting the average production cost over a plant’s lifetime, is substantially lower compared to standard technologies. This translates to a strategic advantage, making low carbon hydrogen an economically viable and environmentally responsible choice.

A global carbon footprint game-changer
By choosing LCH technology, you make a significant positive impact on the carbon footprint of your hydrogen production. Our approach stands out as a cost-effective alternative, providing lower capital and operational costs compared to conventional technologies. Manufacturing CCS-enabled (blue) hydrogen at scale becomes a crucial early step in the global pursuit of net zero emissions, contributing to a sustainable future for our planet.

Reforming precision: ATR and GHR in low carbon hydrogen production

Johnson Matthey is the market leader in syngas with an expertise in deploying world scale plants. We offer customers two tailored solutions to low carbon hydrogen production. Our LCH technology flowsheets leverage a standalone ATR or an ATR-GHR combination, which can enable up to 99% CO₂ capture.1

Autothermal reforming (ATR)
  • Mature technology
  • Higher CO₂ capture at lower CAPEX compared to SMR
  • Exceeds current standards for carbon intensity to be classified as low carbon hydrogen

Johnson Matthey ATR GHR hydrogen technology

Autothermal reforming (ATR) and Gas heated reforming (GHR) combination
  • Higher feedstock efficiency2
  • Lower carbon intensity2
  • Exceeds current standards for carbon intensity to be classified as low carbon hydrogen
