Participant — Arculus provides an internal aluminium/aluminium oxide coating for oil and gas pipelines, applied using the SputterPig™ robotic system. This coating reduces friction, which can improve flow efficiency and lower operational costs. It also extends pipeline service life. The coating enables the safe transport of CO₂ and hydrogen by blocking hydrogen permeation and enabling self-healing of microcracks. These properties help mitigate hydrogen embrittlement and support the adaptation of existing pipeline infrastructure for decarbonisation efforts.

Participant — CYTOK develops catalytic methanation reactors based on the Sabatier process, scalable up to the megawatt range. The company also develops emission-free combustion systems for the renewable methane it produces. These decentralised energy solutions operate entirely on self-generated power, utilising surplus energy to produce hydrogen, which is subsequently converted into methane through power-to-gas technology.

Participant — DeCarbon Technology is developing a Direct Air Capture (DAC) system designed to combine high CO₂ capture efficiency with low energy consumption. The system uses solid amine adsorbents in porous structures to capture CO₂ from air. Sorbent regeneration is powered by low-grade waste heat – operating below 100°C – significantly reducing energy demands. Once captured, the CO₂ is permanently sequestered through mineralisation, reacting with industrial waste to form stable carbonates.

Participant — Ecolectro has developed affordable, scalable Anion Exchange Membrane (AEM) electrolysers that reduce the need for scarce metals and toxic chemicals. By operating efficiently in alkaline conditions, the technology replaces costly, scarce materials like iridium, titanium, and PFAS with stainless steel and non-precious metal catalysts.

Participant — Electrochaea has developed a bio-methanation technology that uses a proprietary biocatalyst to convert CO₂ and H₂ into renewable methane in a highly productive and flexible manner. This patented process operates within a bioreactor, enabling high-efficiency e-methane production at 65°C and 10 bar pressure.

Participant — HGenium scales and commercialises novel thermochemical water splitting technologies with integrated direct air capture (DAC) to produce green hydrogen and capture CO₂. The approach aims to offer a scalable and cost-effective pathway for combined hydrogen production and carbon removal.

Participant — Hydrogen Innovation is developing Anion Exchange Membrane (AEM) electrolysers for low-cost, decentralised green hydrogen production. The electrolysers use nickel-based, non-precious metal catalysts and proprietary membranes, eliminating reliance on iridium and platinum. A custom stack design helps to improve efficiency and reduce costs.

Participant — Meloon is developing a graphene oxide membrane for post-combustion CO₂ capture directly from industrial flue gas. The membrane operates mechanically – without solvents or degradation – and functions as a molecular sieve with CO₂-selective pores. Its ultra-thin, durable structure enables high flux separation at low pressure, maintaining performance under harsh conditions while reducing energy consumption compared to traditional solvent- or polymer-based systems.

Participant — Naco Technologies has developed a proprietary High-Speed Magnetron Sputtering (HMS) technology, enabling the production of advanced nano-coatings tailored to the demands of green hydrogen production and other low-carbon energy systems.

Participant — NitroFix is developing proprietary electrolyser cell structures, with an strong focus on catalysts and cell components. By facilitating the reaction of water and air within the electrolyser, the system produces green ammonia at low voltage, ensuring low power consumption. This technology integrates advancements in electrolyser design, engineering, and materials science

Participant — Nium has developed a nano-catalyst designed to reduce the energy requirements and emissions associated with ammonia production, compared to traditional fossil-fuel-based methods. The system uses renewable hydrogen to decentralise production, lowering costs and reducing supply chain risks. This approach could make ammonia more accessible to a wider range of industries aiming to reduce their environmental impact.

Participant — Oxylus Energy’s "zero-gap" electrolyser directs captured CO₂ over a proprietary catalyst while purified water flows through the anode. Under applied voltage, CO₂ and protons combine across a specialised membrane to produce e-methanol. The modular design allows the electrolyser cells to be stacked to various scales and integrated into existing fuel supply chains.

Participant — SeaO2 is developing a cost-efficient electrochemical Direct Ocean Capture solution that leverages the ocean’s natural capacity to remove atmospheric CO₂. Designed for scalability, the system aims to enable carbon removal at the gigaton scale.
