United States: new solution allows LPG refuelling without specialised infrastructure

North Carolina-based Alliance AutoGas (AAG), founded in 2010 by Blossman Gas, has received a second patent for its refuelling solution of LPG in a vehicle tank. The innovation will allow vehicles to refuel themselves without Autogas specialised infrastructure.

Utilising a vehicle’s in-tank fuel pump, control valves pull fuel from the remote fuel valve rather than inside the tank. The pump then pushes fuel outside the tank towards the engine, where it is diverted and redirected back in the storage tank through an overfill protection device (OPD) valve. This allows the in-tank fuel pump to move LPG from an external tank to itself instead of requiring an external dispensing pump. This type of innovation will allow LPG refuelling with a residential tank at a residence with just a hose connection.

Jessie Johnson, retired in 2017 as vice president of sales and marketing of Blossman Gas after 46 years in the industry, and David Kennedy, director of Autogas design at Alliance AutoGas, are the inventors of the patent.

“Throughout my time at Blossman Gas and Alliance AutoGas, I always enjoyed being a part of the ground-breaking innovation that we worked towards,” commented Johnson. “David Kennedy and I, along with everyone else involved with the company, is pursuing technology that will enable the growth of the Autogas industry and bring it closer to residential opportunity.”
