NGVi is the new standard of NGV training for organizations that truly care about safety.

When you’re launching an NGV program—whether for a fleet, a fuel retailer or a vehicle dealership, safety is your top concern. You’re passionate about making sure your customers, your employees and the general public are not exposed to any unnecessary risks. That’s where we fit in.

As the leading provider of NGV training in North America, we know safety. We live safety. We teach safety. We train the full chain of NGV users—from drivers to vehicle technicians to fueling station maintenance technicians to service managers and supervisors. We also train fueling station designers, fire marshals, code officials and first responders. But we don’t stop at training. We also size and design CNG stations and evaluate vehicle maintenance facilities for the use of CNG or LNG.

Mission Statement

NGVi’s mission is to provide the highest quality and most relevant technical training and consulting on natural gas vehicles and fueling for the transportation industry in North America.  Focused on safety, our training provides full awareness of the complexities of inspecting, maintaining and diagnosing natural gas vehicles and fueling stations.
