SUISO ANNOUNCES FIRST COMMERCIAL SALE OF GAS DECARBONISATION SYSTEM TO THE AMRC

Sheffield, UK – 7 May 2026 – Suiso Limited (“Suiso”), the Sheffield-based cleantech company, today announces the commercial sale of its gas decarbonisation system to the University of Sheffield Advanced Manufacturing Research Centre (“AMRC”).  Using proprietary technology combining microwave energy and a catalyst, the system reduces carbon emissions from existing gas-based industrial processes without requiring costly infrastructure changes.

Industrial heat accounts for nearly one-fifth of global greenhouse gas emissions.  In the UK, industrial processes contribute around 10–12% of total emissions, the majority of which is heat-related.  For high-temperature processes, electrification is often not yet viable—making emissions reduction from existing gas-based operations a key challenge.

Suiso’s approach uses microwave energy and a proprietary catalyst to remove carbon from natural gas prior to combustion, capturing it in solid form rather than emitting it as CO₂.  This carbon is upgraded by Suiso into activated carbon — a high-value material used in water purification, air treatment and industrial filtration.

The deployment at the AMRC reflects the challenge of reducing emissions from high-temperature industrial processes, where practical solutions remain limited.  Following an extensive evaluation, the AMRC selected Suiso’s system as it delivers meaningful emissions reductions while remaining compatible with existing operations.

As a leading industrial research centre working with a wide range of manufacturers, the AMRC will use the system to gain valuable insights into the challenges arising from the “fuel switch” – the transition from traditional natural gas to low-carbon alternatives.

By hosting Suiso’s technology, the AMRC provides a dedicated testbed environment where industrial partners can test and de-risk this transition within their own operations, ensuring a seamless introduction into their facilities.

This sale is the latest example of increasing demand for practical, cost-effective decarbonisation solutions for gas-based processes, positioning Suiso strongly in this market.

Stuart McKnight, CEO of Suiso, commented:
“We are grateful to the AMRC for their confidence in our technology and for deploying it in their operations today and helping drive its adoption across the industries they support over time. This sale marks a significant milestone in the transition to cost-effective, low-carbon industrial processes.  Converting emissions into value is what we do at Suiso.”

“We would also like to thank the South Yorkshire Mayoral Combined Authority for its continuing support, again highlighting South Yorkshire’s leading role in industrial decarbonisation.”

Matthew Cawood, Head Of Castings at the AMRC commented:
“High-temperature industries have traditionally been the hardest to decarbonise, but finding a solution is now a necessity.  We are adopting Suiso’s technology to demonstrate to our partners that they can slash emissions immediately without needing to reinvent their entire operation.”

“By integrating this system into our work at the AMRC, we’re proving that businesses can meet their environmental goals while keeping their production lines running and staying competitive. We look forward to working with our partners and Suiso to de-risk and demonstrate the impact of this technology and drive its adoption across the manufacturing sector”.

SUISO COMPLETES SUCCESSFUL PILOT DEMONSTRATION OF ITS GAS DECARBONISATION TECHNOLOGY

Sheffield, UK – 19 September 2025 – Suiso Limited (“Suiso”), the Sheffield-based cleantech company developing breakthrough gasdecarbonisation technology, today announced the successful completion of a three-month pilot demonstration at the University of Sheffield’s Energy Innovation Centre (“EIC”). The milestone marks a significant step forward in proving Suiso’s capability to remove carbon from hydrocarbon gases at industrial scale, providing a practical new route for hard-to-electrify sectors to cut emissions immediately.

The pilot tested Suiso’s methane-pyrolysis system on an industrial gas-fired furnace with a power rating of up to 300 kW, operating under real-world production conditions—including cyclical operations, cold starts and emergency shut-downs. The system consistently delivered stable hydrogen/natural-gas blends with zero lost-time events, while maintaining operational performance and demonstrating compatibility with industrial heat-processing environments.

In a further validation of technology readiness, Suiso completed a successful casting of an aerospace test component provided by the University of Sheffield’s Advanced Manufacturing Research Centre (“AMRC”), confirming that the decarbonised fuel blend could support demanding, precision-led manufacturing processes.

The demonstration also drew substantial interest from industry. Senior engineers and decision-makers from more than 30 companies across heavy manufacturing, food and beverage, ceramics, healthcare and local government attended site visits during the pilot period, highlighting strong commercial appetite for near-term decarbonisation solutions that do not depend on largescale hydrogen infrastructure or full electrification.

The Pilot received significant support from the South Yorkshire Mayoral Combined Authority (“SYMCA”) who provided significant support before, during and after the demo but also contributed financially via their Investment Zone initiative.

Stuart McKnight, CEO of Suiso, commented: “It is with great pleasure that we announce the successful completion of this landmark pilot. Demonstrating our technology at the University of Sheffield’s Energy Innovation Centre marks a significant step forward for Suiso and for the wider industrial decarbonisation agenda. Over the past three months we have shown, in real-world operating conditions, that carbon can be removed from gas pre-combustion in a way that is practical, reliable and commercially compelling for industry.

Many businesses have told us they face an impossible choice: they cannot afford full electrification, and they cannot yet access lowcost, low-carbon hydrogen. This pilot proves there is a viable alternative available now. Our system offers a credible, near-term pathway for manufacturers to cut emissions without disrupting operations or relying on uncertain external fuel supplies.

Reaching this milestone has been a genuine team effort. I would like to extend my sincere thanks to SYMCA, the EIC and the AMRC for their outstanding support, and to the more than 30 companies and organisations who attended the demonstrations and provided invaluable feedback. Their engagement reinforces the strong demand for practical decarbonisation technologies across the UK’s industrial base.

We look forward to building on this momentum as we move towards commercial deployment.”
