Frequently Asked Questions

decarbX is a US-based technology company that delivers measurable fuel efficiency and validated emissions reduction for diesel-powered assets. We install real-time fuel flow and oil quality sensors directly on your equipment, then connect them to our cloud intelligence platform to give you accurate, verifiable data on exactly how much fuel your fleet is using and where savings are being made. We are the authorized technology integrator for a leading fuel optimization technology provider.

decarbX combines two things: a fuel optimization catalyst and a real-time measurement system. The Rentar fuel optimizer uses a catalytic process to condition diesel fuel molecules before combustion, making them burn more completely and efficiently. This reduces the energy wasted as unburned hydrocarbons, lowers combustion temperatures, and cuts harmful emissions including CO, NOx, and CO2. On top of that, our IoT sensor platform measures the actual fuel savings in real time so you always know exactly what the technology is delivering. 

Decarbonization for diesel-powered equipment means reducing the carbon emissions produced by your fleet without necessarily replacing the equipment. While electrification and alternative fuels are long-term goals for many industries, most heavy diesel fleets will continue operating for years or decades. Intelligent decarbonization is the practical path forward right now. It means using real-time measurement, operational optimization, and verified data to reduce emissions at the source while improving efficiency and asset performance. 

Each asset receives a compact sensor package that includes dual fuel flow meters on the supply and return fuel lines, oil quality and contamination sensors, an engine data interface via the J1939 CAN bus, GPS and duty cycle telemetry, and a dual-mode IoT gateway for encrypted data transmission via cellular or satellite. The Rentar fuel optimizer is also installed inline on the fuel supply line. All hardware is designed for harsh operating environments including mining, construction, marine, and rail applications. 

Installation is straightforward and designed to minimize downtime. Most assets can be fitted within a few hours. There are no engine modifications required and no need to take equipment out of service for extended periods. Our team works with your maintenance schedule to keep disruption to a minimum. 

 No. decarbX does not require any permanent engine modifications. The sensor package and fuel optimizer install on existing equipment using standard connections. Your engines continue to operate exactly as designed. The system works alongside your existing ECU, not in place of it.

 Fuel savings are verified through direct physical measurement using dual fuel flow meters on the supply and return lines. This gives a precise net fuel consumption figure that is independent of ECU estimates. Our cloud platform cross-validates data across time, assets, and operating conditions using an AI-driven anomaly and consistency checking engine.

Our results are backed by independent third-party field studies including a verified mining truck study conducted on CAT 793F trucks at a Tier One mining operator Brazil, which recorded approximately 5% fuel reduction, 18% reduction in CO emissions, and 3% reduction in CO2 emissions. Testing was conducted by CSL Laboratório Ambiental using US EPA and ABNT protocols. Locomotive testing was independently conducted by the Engine Systems Development Centre (ESDC) in Canada under Association of American Railroads (AAR) RP 503 protocol, recording approximately 7% fuel reduction at idle speed and 15% reduction in NOx emissions.

CO2 emissions are calculated from actual measured fuel consumption using standard emissions conversion factors. Because decarbX measures true net fuel consumption rather than relying on ECU estimates, the resulting CO2 figures are more accurate and defensible than those derived from calculated data. Emissions outputs are reported in metric tons of CO2 equivalent (MtCO2e) and are formatted to meet compliance, ESG, and stakeholder reporting requirements. 

decarbX works on any diesel-powered asset. This includes mining trucks and excavators, construction equipment such as loaders and dozers, agricultural tractors, on-highway and off-highway trucks, locomotives, tugboats and marine vessels, industrial gensets, and stationary boilers. If it runs on diesel, we can measure and optimize it.

Yes. decarbX has verified performance data across multiple industries and asset types. Key references include a CAT 793F mining truck study at Vale SA in Brazil with independently verified fuel and emissions reductions, a locomotive study conducted by ESDC Canada under AAR protocols, and a tugboat field study using Niigata 8L28HX medium-speed diesel engines at 2,500 kW power, recording approximately 5% actual fuel efficiency improvement. All studies used physical flow measurement and independent third-party verification.

decarbX uses the GHGsolve Intelligence Platform, a cloud-based dashboard that gives different teams the visibility they need. Equipment managers can see asset-level fuel consumption, engine health, and efficiency data in real time. Fleet and operations managers can aggregate data across sites and regions. Sustainability and leadership teams can access compliance-ready ESG reporting with auditable data trails. Access is role-based, so each person sees what is relevant to their function without being overwhelmed by data they do not need.

decarbX provides audit-ready data that supports both internal and external ESG reporting. Because our measurements are based on physical sensors rather than models or estimates, the resulting emissions figures are defensible in front of regulators, auditors, investors, and board-level stakeholders. The platform produces compliance-ready reports and maintains a persistent data layer for lifecycle analysis and trend reporting over time.

No, and it was never designed to. decarbX is a practical solution for the diesel fleets operating right now, many of which will continue operating for years or decades before electrification becomes viable at scale in heavy industries like mining, rail, and marine. decarbX reduces the emissions and fuel costs of those assets in the meantime, and the verified data it generates can support transition planning when the time comes. Think of it as the smartest thing you can do with the fleet you already have.
