October 22, 2026. Westport Fuel Systems Inc. has changed its name to Aetherion Technologies Inc. The new name reflects the company’s sharpened focus on delivering proven, commercially ready technologies that enable affordable, lower-emission heavy-duty transportation.
Aetherion’s new identity builds on the fundamental concepts on which Professor Philip Hill co-founded Westport in 1995 and invented HPDI™ fuel system technology: keep the diesel engine that has moved the world for decades, but change the fuel so it runs cleaner.
Aetherion’s portfolio includes a majority ownership interest in Cespira™, a joint venture with Volvo Group focused on the HPDI fuel system technology, as well as wholly owned high-pressure compressed natural gas (CNG) fuel storage system, high-pressure systems and components and control technologies. Together, these technologies support natural gas, renewable natural gas which includes biogas and Bio-LNG (RNG) and hydrogen applications, enabling original equipment manufacturers (OEMs) and commercial fleets to cost effectively meet performance requirements, evolving regulatory obligations and climate targets. Market drivers for Aetherion’s solutions include rising demand for cost‑effective long‑haul alternatives, tightening emissions standards and broader adoption of practical, lower‑emission fuels.
