Balfour Beatty and Industrial Chemicals Limited are trialling Engine Carbon Clean (ECC), a hydrogen-based system that aims to reduce emissions and improve fuel efficiency across their industrial fleets, signalling a shift towards innovative near-term decarbonisation solutions.
Balfour Beatty and Industrial Chemicals Limited (ICL) have moved to broaden their fleet decarbonisation measures by adopting Engine Carbon Clean (ECC), a hydrogen‑based engine cleaning system that firms say reduces carbon deposits, improves fuel efficiency and lowers tailpipe emissions.
According to the original report, ECC operates through a patented on‑demand hydrogen generator that produces oxyhydrogen gas and introduces it into the engine air intake so the engine draws in what it requires. The process is intended to remove combustion chamber and intake deposits, with the manufacturers and trial partners asserting measurable reductions in CO₂, CO, NOx and N₂O as well as improved fuel consumption.
Balfour Beatty began trials on a Plasser & Theuer compact tamper used in rail maintenance as part of its Scope 1 emissions mitigation work. The company reports that a test designed to replicate a full year’s operation within standard maintenance cycles delivered a 15.79% reduction in emissions. Balfour Beatty said it now intends to roll ECC out across its entire tamper fleet. The move sits alongside a string of other decarbonisation pilots by the contractor , including the M77 Hydrogen hybrid hydrogen retrofit trials on heavy vehicles and tests of Syntech biofuel and site energy management systems such as EcoNet , underlining a multi‑pronged approach to lowering on‑site and fleet emissions.
ICL’s adoption followed empirical testing at Millbrook Proving Ground in Bedford, conducted in partnership with Advanced Hydrogen Technologies. The firm reported measurable improvements in emissions and fuel performance, prompting deployment of ECC on approximately one‑third of its 90‑vehicle West Thurrock fleet. ICL said the initial fitment yielded more than a 7% reduction in emissions and fuel costs and that it plans to extend the technology across its national operations.
Industry sources caution that while in‑service trials and manufacturer data are promising, independent long‑term verification across varied duty cycles is important to confirm sustained benefits and to quantify impacts on maintenance intervals, aftertreatment systems and whole‑life carbon. Speaking to the broader market, fleet‑management reporting has noted similar percentage gains in early trials but emphasises the need to consider interactions with modern diesel particulate filters, selective catalytic reduction systems and warranty terms.
For infrastructure and industrial operators, ECC presents a retrofit option that does not require engine replacement and can be positioned alongside low‑carbon fuels, electrification and hydrogen powertrain pilots. Industry data shows that organisations are increasingly adopting layered strategies , combining behavioural, fuel, hardware and systems interventions , to meet corporate and regulatory carbon targets. The companies involved have framed ECC as a practical, near‑term measure to drive Scope 1 reductions while longer‑term transitions proceed.
The company statements characterise ECC as an operationally simple, emissions‑reducing intervention. Independent stakeholders will be watching for wider peer‑reviewed data and cross‑fleet, long‑duration trial outcomes to assess scalability, total cost of ownership and any unintended effects on engine systems. In the meantime, Balfour Beatty and ICL’s decisions exemplify how large industrial fleet owners are trialling hydrogen‑adjacent technologies as part of a broader decarbonisation toolkit.

- https://www.balfourbeatty.com/media-centre/latest/balfour-beatty-pioneers-hydrogen-based-engine-cleaning-technology-to-cut-carbon-emissions-across-its-rail-fleet/ – Balfour Beatty has successfully trialled Engine Carbon Clean (ECC) technology on a compact tamping machine, achieving a 15.79% reduction in emissions. ECC uses on-demand hydrogen to remove carbon build-up in combustion engines, enhancing fuel efficiency and reducing harmful emissions. The company plans to implement ECC across its entire tamper fleet, marking a significant step in reducing carbon emissions and improving engine performance in rail operations.

ECC introduces oxyhydrogen gas into the engine’s air intake, removing carbon deposits and enhancing efficiency. Balfour Beatty’s trial on rail maintenance equipment resulted in nearly a 16% emissions reduction, while ICL’s truck trials saw over a 7% reduction in emissions and fuel use. Both companies plan to expand ECC implementation across their operations.

The project, in collaboration with ULEMCo, Logan Energy, and PlusZero Power, aims for a 30% reduction in emissions. Trials on two salt spreader HGVs and one Impact Protection Vehicle (IPV) have shown promising results, with spreaders achieving around a 26% carbon reduction during road tests. The project is part of Balfour Beatty’s efforts to establish Scotland’s first construction hydrogen hub.
- https://www.balfourbeatty.com/sustainability/sustainability-showcase/driving-decarbonisation-with-syntech-biofuel/ – Balfour Beatty is trialling Syntech biofuel, a sustainable alternative to diesel, produced from UK waste cooking oil. The biofuel can be used as a 100% drop-in replacement for diesel engines, resulting in an 80–90% reduction in carbon emissions. Balfour Beatty has agreements with several Original Equipment Manufacturers (OEMs) and suppliers to use the biofuel, aiming to reduce emissions while preparing for low-carbon plant options to become more widely available and feasible for use at scale.
