Diesel Tech Industries

What Diesel Tech Industries does

Diesel Tech Industries Ltd. (DTI) is a privately held Canadian transportation technology company founded in 2005 in Edmonton, Alberta, operating as a subsidiary of Diesel Tech Truck Repair (established 1999). DTI designs, engineers, and manufactures the Guardian family of in-vehicle electronic systems, with its flagship product being the Guardian Hydrogen Diesel System (HDS) — a patented hydrogen-diesel dual-fuel retrofit that integrates hydrogen as a secondary fuel into existing diesel engines via proprietary multi-port injection and full ECM integration, with machine learning-based controls reported to achieve up to 90% hydrogen energy replacement at certain operating loads. The company also produces Transport Canada and FMCSA-certified electronic logging hardware (Guardian ELOG), an emergency engine shutdown system (Guardian EPASS), a fleet data logger (Guardian FDL), a turbo cooldown timer, and ECM interface/simulator tools, all backed by cloud-based Guardian Dashboards for fleet analytics, IFTA and GHG reporting. DTI holds Transport Canada third-party ELD certification (#6T02) and FMCSA approval, and has won a 2025 Hydrogen Leader of the Year award (Canadian Hydrogen Convention) for COO Rebecca Goldsack.

DTI serves heavy-duty diesel fleet operators, municipal governments, transit and motorcoach operators, airport ground services, and commercial trucking fleets, with a primary focus on retrofit-based decarbonization that avoids full vehicle replacement. Its business model combines one-time hardware sales (HDS retrofit kits, ELD tablets, EPASS, FDL) with recurring subscription revenue (Guardian ELOG with transparent all-in-one monthly pricing, FDL and HDS cloud data services) and professional installation services delivered through a channel partner network — including Velocity Truck Centre (12 locations in Alberta/BC), MTB Transit Solutions (Ontario), Creative Truck Performance (Saskatchewan), and HVMS (New Zealand/Australasia/SE Asia) — alongside direct enterprise sales to municipal and transit accounts such as the City of Edmonton, Edmonton International Airport, and Diversified Transportation. The company employs approximately 30 multidisciplinary technical specialists, has secured CAD $2M in Emissions Reduction Alberta grant funding and NSERC Alliance research support, and is headquartered at 14215 120 Ave NW, Edmonton, with policy leadership via the COO's role as Board Chair of Hydrogen Alberta.

• Cummins: Cummins is a major diesel and alternative fuel engine manufacturer with hydrogen and natural gas programs. Broad incumbent whose engines DTI's HDS retrofits target (including Cummins 9L in City of Edmonton pilot), representing both a customer-adjacent and a potential competitive threat.
• Ballard Power Systems: Ballard is a leading hydrogen fuel cell manufacturer serving heavy-duty mobility including buses and trucks. A broad incumbent competing for the same fleet decarbonization budget DTI targets, but with full fuel cell rather than dual-fuel architecture.
• Samsara: Samsara is a broad IoT and fleet management platform serving commercial fleets with telematics, ELD, and equipment monitoring. Competes with DTI's Guardian ELOG and Guardian FDL in the fleet compliance/analytics category.

Direct peers

• Geotab: Geotab is a leading fleet telematics and ELD provider. Comparable to DTI's Guardian ELOG product line targeting commercial trucking compliance and fleet data analytics.
• Westport Fuel Systems: Westport develops alternative fuel systems (CNG, LNG, hydrogen) for transportation engines. Directly comparable to DTI's hydrogen-diesel dual fuel retrofit approach targeting heavy-duty fleets.
