What D2Zero does

D2Zero Limited is a private decarbonisation and clean energy solutions platform formed in January 2024 by growth-investment firm SCF Partners, headquartered in Aberdeen's Energy Transition Zone. The group combines six operating companies — Score Group (flow control, gas turbines, emissions management, including the proprietary MIDAS® Meter leak-detection technology), Hydrasun (integrated fluid transfer, hydrogen refuelling stations), Fuel Cell Systems (proprietary HyQube and HyFleet hydrogen refuelling systems, modular electrolysers), Powerstar (voltage optimisation, battery storage, microgrids), nexos (formerly Global E&C; design, engineering, EPCm for conventional and emerging energy, plus CCS), and Kelton (precision flow measurement and hydrogen metering consultancy acquired October 2024) — supported by additional subsidiaries OSL Consulting Engineers, Kampen Valve B.V., and control-solutions businesses BLJ In-Situ Solutions, Drake Controls, and KC Controls. The platform serves oil & gas operators, hydrogen developers, utilities, and industrial energy users across the UK, Netherlands, Denmark, the Middle East, North America, and Australia, with named customers and partners including BP, TotalEnergies, Air Liquide, Ørsted, Energinet, National Gas, and Zero Petroleum.

D2Zero's technology stack spans proprietary hardware and software: the MIDAS® Meter detects internal through-valve leakage as part of Score Group's Emission Elimination Program; the Operate platform (Score/asset55) provides near real-time emissions analytics; HyQube and HyFleet systems deliver hydrogen refuelling infrastructure (deployed at Roosendaal for TotalEnergies/Air Liquide and along the M4 for HyHAUL); Kelton's high-pressure hydrogen metering was validated at National Gas's FutureGrid facility; and nexos applies modular DirectFT® Fischer-Tropsch integration with Zero Petroleum at Plant Zero.1. With 4,000+ employees, 73+ global locations, and combined revenues exceeding £500M at formation, D2Zero monetises primarily through B2B project-based contracts for engineering services, manufactured hydrogen and electrical hardware, and specialist consulting.

Revenue mechanics rest on four pillars: emissions reduction (leak detection and valve management as professional services and product sales), clean hydrogen (hardware sales plus installation and ongoing support), power efficiency (equipment plus advisory), and carbon capture and storage (engineering and modularised project delivery). GTM is enterprise field sales targeting major oil & gas, utility, and industrial operators, with cross-portfolio collaboration securing large framework agreements; marketing is concentrated in energy-sector conferences, thought leadership by CEO Bob Drummond, and policy engagement through OEUK and the Net Zero Technology Centre. D2Zero remains wholly owned by SCF Partners with no public listing identified.
