Zero Emission Industries (ZEI), formerly Golden Gate Zero Emission, develops hydrogen refueling and fuel-cell power systems for maritime and heavy-duty applications and is best known as the technology team behind the Sea Change ferry launched in 2021. The company says it has patented hydrogen refueling technology and builds integrated fueling and power solutions aimed at solving practical customer and supplier challenges. ZEI plans to offer integrated fueling and power system products in 2024 to expand commercial deployments. Leadership frames the business as mission-driven to decarbonize maritime transport and to expand into other hard-to-decarbonize sectors. Strategic partnerships with Chevron New Energies, Trafigura and Crowley are positioned to provide experience, insights and infrastructure to scale operations and meet customer demand. The company is headquartered in San Francisco and emphasizes tangible, defensible technology rather than theoretical solutions.

Founded in 2021, OXCCU is developing proprietary catalysts and reactor designs that directly hydrogenate CO₂ to create hydrocarbon syncrude branded as OXFUEL, which can be refined into jet-fuel-grade SAF. Its single-step, iron-based Fischer-Tropsch process eliminates the RWGS stage and reduces hydrogen demand, promising lower capital and operating costs than competing e-fuel pathways. The company operates from Begbroke Science Park and London Oxford Airport, where its OX1 demonstration plant was validated in 2024. OXCCU is positioning OXFUEL to help the UK meet its target of 10% SAF in jet fuel by 2030 and is now researching how its fuel can limit non-CO₂ warming effects such as soot-induced contrail formation. Financially, the start-up secured €20.6 million of initial funding in June 2023, followed by a €23.7 million round in September 2025, and most recently obtained a €2 million grant from the ATI Non-CO₂ Programme. These funds support technology scale-up, commercial deployment and climate-impact validation, underscoring OXCCU’s emergence as a leading UK climate-tech innovator.

C-Zero builds methane pyrolysis reactors that heat natural gas in the presence of a proprietary catalyst to break hydrogen’s bond with methane, producing hydrogen and solid carbon. The company positions that hydrogen for today’s industries such as ammonia and petrochemical production and for potential future uses including transportation and steel. The solid carbon byproduct could be reused in applications ranging from asphalt to lithium-ion batteries. C-Zero says its process uses just a few kilowatt-hours of electricity per kilogram of hydrogen, which it argues enables lower-cost, low-carbon hydrogen compared with electrolyzer-based green hydrogen. By using readily available natural gas and existing infrastructure, the company aims to make low-carbon hydrogen anywhere customers have natural gas or LNG. C-Zero previously raised a $34 million round in 2022 that PitchBook valued at $124 million post-money. CEO Zach Jones says the current raise should extend runway toward a Series B next year and help the company reach cash-flow positivity. C-Zero has developed a proprietary process for transforming natural gas into clean hydrogen and a solid carbon co-product using methane pyrolysis. The company closed a $34 million financing round to build its first pilot plant, expected online in Q1 2023. The pilot is planned to produce up to 400 kg of hydrogen per day from natural gas with no CO2 emissions. The round was led by SK Gas and included new investors Engie New Ventures and Trafigura, alongside participation from existing investors Breakthrough Energy Ventures, Eni Next, Mitsubishi Heavy Industries, and AP Ventures. C-Zero positions the technology as a pathway to decarbonize natural gas and as a producer of “turquoise” hydrogen. The financing will support piloting and demonstration work to scale the technology. C-Zero is commercializing a proprietary thermocatalysis process that transforms natural gas into hydrogen and a solid carbon co-product. The technology, developed at the University of California, Santa Barbara, uses methane pyrolysis to split methane into hydrogen and solid carbon. The hydrogen can be used to decarbonize applications such as electrical generation, process heating and the production of commodity chemicals like ammonia. When renewable natural gas is used as the feedstock, the process can be carbon negative by extracting CO2 from the atmosphere and storing it as solid carbon. C-Zero plans to accelerate its first commercial-scale deployment of this drop-in decarbonization technology and is hiring in the Santa Barbara region. The company raised $11.5M in Series A financing to support these efforts.
