GE Researchers Developing At-Home Refueling Station for NG Vehicles
In what could help fuel widespread adoption of NG vehicles in the US and globally, GE researchers, in partnership with Chart Industries and scientists at the University of Missouri, have been awarded a program through Advanced Research Projects Agency for Energy (ARPA-E) to develop an affordable at-home refueling station that would meet ARPA-E's target of $500 per station and reduce re-fueling times from 5-8 hours to less than 1 hour.
Natural gas prices are at an all-time low and the number of natural gas (NG) vehicles is increasing, but several barriers are preventing greater adoption of this vehicle technology. These include the inconvenience and low availability of refueling stations and limited driving range of NG vehicles.
At-home refueling stations are sold today, but are expensive (~$5000) and require long re-fueling times. The 5-8 hours required to refuel an NG vehicle often leaves overnight re-fueling as the only the viable option for vehicle owners. While these barriers can be more easily managed by established fleets, they are not practical for passenger vehicles parked in the driveway or garage at home.
“Since the beginning of the automotive industry, cars and trucks have driven on diesel fuel or unleaded gas,” said Anna Lis Laursen, project leader and chemical engineer at GE Global Research. “But with new technologies to reduce the cost of NG re-fueling and continued improvements in battery technology, the prospects for vehicles that run on alternative fuels will only grow.”
Laursen added, “The goal of our project is to design an at-home refueling station that is much simpler in design, more cost effective and reduces re-fueling times to under an hour. By reducing the time and cost of re-fueling, we can break down the barriers that are preventing more widespread adoption of NG vehicles. If we can meet our cost targets, the price of a home refueling station would be less than typical appliances in the home such as a dishwasher or stove.”
