Balfour Beatty hydrogen engine cleaning: emissions and asset-life gains for rail engineers
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
Balfour Beatty Rail is rolling out Engine Carbon Clean (ECC), an Advanced Hydrogen Technologies system that injects on-demand hydrogen into engine air intakes, across its entire tamper fleet after trials showed a 15.79% emissions reduction over a simulated full-year maintenance cycle. The non-intrusive process targets carbon build-up in combustion engines to improve fuel efficiency, extend engine life and cut CO₂, CO, NOx and N₂O, with road-vehicle deployments reporting up to 30% fuel and CO₂ savings. Delivered with K2C Rail and 1stinrail (RSK Group), ECC is configured to meet rail standards and support IFRS-aligned ESG reporting.
Technical Brief
- Similar hydrogen-based decarbonisation of legacy diesel fleets offers a retrofit option where full electrification is constrained.
Our Take
Among the 119 Infrastructure stories in our database, very few UK-based pieces feature quantified emissions benefits like the 15.79% reduction reported here, which gives Balfour Beatty a concrete benchmark for future sustainability reporting under International Financial Reporting Standards.
If ECC’s hydrogen-based treatment consistently delivers up to 30% fuel and CO₂ savings on road vehicles, it could materially improve whole-life plant costs on Balfour Beatty Rail worksites in the United Kingdom, especially where fuel is a major component of preliminaries.
Because this is tagged both as Product and Sustainability rather than a specific Project, it signals Balfour Beatty is trialling a fleet-wide operational change rather than a one-off site initiative, which can make it easier to cascade similar technologies across other UK infrastructure contracts.
