(The Chemical Engineer<\/a>)<\/li>\nThe technology was deployed on 30 trucks<\/strong> \u2014 about one-third of ICL\u2019s fleet at its West Thurrock facility in Essex<\/strong> \u2014 as part of efforts to cut carbon emissions and fuel costs<\/strong> associated with road transport. (The Chemical Engineer<\/a>)<\/li>\nAfter two cleaning cycles<\/strong>, the trials showed about a 7 % reduction in emissions and fuel costs<\/strong>, with potential for further improvements if applied more frequently. (The Chemical Engineer<\/a>)<\/li>\nFollowing the trial, ICL has now signed a three-year contract with Engine Carbon Clean<\/strong>, the company supplying the hydrogen technology. (The Chemical Engineer<\/a>)<\/li>\n<\/ul>\n\n<\/span>How the Hydrogen Technology Works<\/strong><\/span><\/h2>\n<\/span>Hydrogen-Assisted Engine Cleaning<\/strong><\/span><\/h3>\n\nThe system uses hydrogen produced by electrolysis<\/strong> (from water) to clean carbon deposits inside combustion engines. (The Chemical Engineer<\/a>)<\/li>\nHydrogen is injected into the air intake<\/strong>, where it reacts with and helps remove carbon build-up inside the engine \u2014 much like a deep engine \u2018clean\u2019 \u2014 leading to better airflow, improved combustion, and lower emissions. (The Chemical Engineer<\/a>)<\/li>\nBy removing this carbon, the engine \u201cbreathes better,\u201d<\/em> which reduces fuel use and associated emissions regardless of whether the drivetrain runs on diesel or another fuel type. (The Chemical Engineer<\/a>)<\/li>\nThe underlying technology was originally developed in the early 2010s to improve racing car performance and fuel efficiency, but has now been adapted for industrial use. (The Chemical Engineer<\/a>)<\/li>\n<\/ul>\n\n<\/span>Impacts on Emissions and Fleet<\/strong><\/span><\/h2>\n<\/span>Measured Improvements<\/strong><\/span><\/h3>\n\nICL reported its emissions and fuel costs dropped by around 7 %<\/em> after two hydrogen-cleaning cycles on the trial truck engines. (The Chemical Engineer<\/a>)<\/li>\nExecutives involved in the trial said the results were \u201cvery encouraging\u201d<\/strong> and further reductions might come with additional cleans per year. (The Chemical Engineer<\/a>)<\/li>\n<\/ul>\n<\/span>Broader Operational Plans<\/strong><\/span><\/h3>\n\nAfter the trial\u2019s success, ICL plans to deploy the hydrogen cleaning technology across its entire UK fleet<\/strong> at facilities in England and Wales. (The Chemical Engineer<\/a>)<\/li>\nTransport currently accounts for a significant proportion<\/em> of ICL\u2019s emissions \u2014 road fuel made up ~28 % of its total emissions in 2024 \u2014 so cutting this area is key to its sustainability plans. (The Chemical Engineer<\/a>)<\/li>\n<\/ul>\n\n<\/span>Why This Matters<\/strong><\/span><\/h2>\n<\/span>Industrial Decarbonisation<\/strong><\/span><\/h3>\n\nHeavy-duty transport, including trucks, is one of the harder-to-decarbonise sectors<\/em> because of long ranges and high power demands. Trials like this help demonstrate practical pathways to reduce emissions now<\/em>, even before full electric or hydrogen-powered vehicles are widely adopted.<\/li>\n<\/ul>\n<\/span>Supplemental to Vehicle Electrification<\/strong><\/span><\/h3>\n\nWhile the shift to electric and fuel cell trucks<\/strong> (e.g., hydrogen fuel cell HGV corridors being developed in the UK) is underway, intermediate technologies like hydrogen engine cleaning can offer near-term emissions gains for existing fleets<\/strong>. (Driving Hydrogen<\/a>)<\/li>\n<\/ul>\n<\/span>Industry Commentary<\/strong><\/span><\/h3>\n\nSome commentators see this kind of hydrogen application as part of a multi-layered decarbonisation strategy<\/strong>, especially useful where replacing entire fleets isn\u2019t immediately feasible.<\/li>\nOthers caution that true decarbonisation<\/em> will ultimately depend on moving toward zero-tailpipe solutions<\/strong> such as battery electric or fuel cell vehicles \u2014 but that doesn\u2019t diminish the value of interim improvements like engine carbon cleaning.<\/li>\n<\/ul>\n\n<\/span>Key Takeaways<\/strong><\/span><\/h2>\n\n\n\nAspect<\/th>\nDetails<\/th>\n<\/tr>\n<\/thead>\n\n\nCompany<\/strong><\/td>\nIndustrial Chemicals Limited (ICL), UK speciality chemicals producer (The Chemical Engineer<\/a>)<\/td>\n<\/tr>\n\nTechnology<\/strong><\/td>\nHydrogen-based engine carbon cleaning from Engine Carbon Clean (The Chemical Engineer<\/a>)<\/td>\n<\/tr>\n\nTrial Results<\/strong><\/td>\n~7 % reduction in emissions and fuel costs after two cleaning cycles (The Chemical Engineer<\/a>)<\/td>\n<\/tr>\n\nNext Steps<\/strong><\/td>\nRolling out technology across the rest of ICL\u2019s fleet (The Chemical Engineer<\/a>)<\/td>\n<\/tr>\n\nSignificance<\/strong><\/td>\nInterim emissions reductions while broader decarbonisation solutions mature<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<\/span>Context in UK Hydrogen Transport Trends<\/strong><\/span><\/h3>\nThis initiative sits alongside other UK hydrogen transport developments \u2014 such as plans for the first hydrogen HGV refuelling corridor along the M4<\/strong>, which will support hydrogen fuel cell trucks and reduce heavy-duty transport emissions on a larger scale under government programmes.
