Mercury Fuel Systems

What Mercury Fuel Systems does

Mercury Fuel Systems Ltd is a UK-based designer and manufacturer of dual-fuel LPG/diesel injection systems for heavy goods vehicles, founded in 2007 and headquartered in Newton Aycliffe, Co. Durham following a 2017 relocation from Avonmouth. Its flagship product, the Quicksilver AFI system, is described as the first fully sequential multipoint LPG injection system specifically developed for the HGV transport sector. The technology combines in-house-designed engine control units with proprietary firmware (including the Gas Butler density-compensation system and Automatic Fuel Interruption logic), an Exhaust Aftertreatment add-on for Euro 6 DPF regeneration in low-speed urban duty cycles, in-house manufactured diesel and LPG fuel tanks, and the proprietary METAL diagnostics software. The system targets 8-16% fuel-cost reduction, 6-13% CO2 reduction, and up to 45% NOx reduction on urban cycles, with a 10-16 month payback at an installation cost of £6,000-£8,000 per vehicle.

The company monetises through three primary streams: one-time hardware sales and installation of Quicksilver conversion kits, recurring annual service contracts at Platinum, Gold, Silver, and Self-Maintenance tiers, and ancillary services including private hire of its 750BHP MAHA chassis dynamometer at £750+VAT per day. Go-to-market is hybrid: a direct enterprise field-sales team engages UK fleet operators, supported by an approved service-centre network (Ford & Slater, FT Commercials, Witney Commercials, Drummond Motor Co, J L Fleet Care) and an exclusive Irish distributor (Alternative Fleet Ltd). Named enterprise customers span fresh-produce distribution (Total Produce), food distribution (Linwoods), plastics manufacturing logistics (Polypipe), haulage (Gallagher Brothers), and energy supply (Calor Gas, which is also a strategic LPG-supply partner). Strategic R&D is directed at extending the platform into LNG, CNG, methanol, and hydrogen fuel systems, and the company actively engages LowCVP and Clean Air Alliance to align with Clean Air Zone and ULEZ regulation.

The business is privately held with no disclosed venture or institutional funding, a headcount of 101-250, and operations limited to the UK and Ireland — a constraint reinforced by the Channel Tunnel prohibition on gas-powered vehicles, which forecloses direct overland expansion into continental Europe.

Revenue model

1. Dual Fuel System Sales: Mercury manufactures and sells the Quicksilver AFI dual fuel conversion systems for HGVs. Customers pay upfront for the hardware and installation. The system replaces a portion of diesel consumption with LPG, creating ongoing fuel savings for operators.
2. Service Contracts: Mercury offers tiered service contracts (Platinum, Gold, Silver, and Self Maintenance) that provide ongoing maintenance and support for the Quicksilver system. These create recurring revenue relationships with customers.
3. Dyno Facility Hire: The 750BHP MAHA chassis dynamometer is available for private hire at £750+ VAT per day, used primarily for R&D but generates additional revenue from external customers requiring vehicle testing.
4. Fuel Tank Manufacturing: Mercury manufactures custom diesel and LPG tanks as part of the largest fabrication group in the UK, supplying tanks to OEM standards for converted vehicles.

Direct peers

• Eminox: Eminox manufactures exhaust aftertreatment and emissions control systems for heavy-duty commercial vehicles, directly comparable to Mercury's Exhaust Aftertreatment System product addressing Euro 6 DPF regeneration in low-speed urban duty cycles.
• Prins Autogassystemen: Prins designs and supplies LPG and CNG fuel injection systems, including multipoint sequential injection technology comparable to Mercury's Quicksilver AFI architecture, serving European automotive and light commercial vehicle markets.
• Clean Air Power: Clean Air Power develops diesel/natural gas dual-fuel systems for heavy-duty commercial vehicles, directly competing with Mercury's Quicksilver AFI system in the same HGV retrofit value chain and customer segments.
• BRC Gas Equipment: BRC Gas Equipment is an Italian manufacturer of LPG and CNG sequential injection systems for motor vehicles, providing directly comparable multipoint injection technology to Mercury's Quicksilver AFI for the broader commercial vehicle conversion market.
• Gasrec: Gasrec operates an LPG (and biomethane) refuelling network for UK HGV fleets and offers dual-fuel conversion partnerships, making it a directly comparable peer in the UK gas-for-trucks ecosystem with overlapping customer base of fleet operators.

Broad incumbents
