SkyMark Unveils 7,000-gallon All-electric Refueler

SkyMark Refuelers unveiled the largest aircraft refueler in the U.S. with an all-electric powertrain on Tuesday at NBAA-BACE 2025. Launched in combination with World Fuel Services and Clay Lacy Aviation, the 7,000-gallon-capacity tanker will be delivered to Clay Lacy’s flagship FBO at California’s Van Nuys Airport (KVNY) at the conclusion of the show and will be used to carry sustainable aviation fuel (SAF).

Doug Wilson, Clay Lacy’s chief business officer for FBOs, noted the irony of FBOs using a conventionally powered refueler with its exhaust emissions to haul and dispense SAF. He added that this was a factor in the company’s decision to acquire the fully electric vehicle.

“Since establishing our sustainability program in 2019, we have continually sought new ways to drive the industry forward and support our company’s environmental goals,” he said. “This impressively engineered refueler sets a new standard in all-electric ground service equipment and allows us to best serve our clients while being a good neighbor to the communities surrounding our airports.”

The vehicle is powered by a 240-kW battery, which SkyMark estimates will supply enough power for it to dispense two full truckloads of fuel and drive 20 miles before requiring an overnight charge. It carries SkyMark’s Gen 2 control system, which provides safety cutoffs and monitors conditions such as battery temperature.

If it detects any parameter approaching exceedance, it will generate a warning to the operator. If those parameters become dangerous, the control system will shut the vehicle down. Qualified under National Fire Protection Association 407—the standard for aircraft fuel serving—the refueler was designed with safety as its primary concern, according to the manufacturer.

“Working alongside World Fuel Services and Clay Lacy Aviation, we are excited to introduce this next-generation EV refueler to the market,” said SkyMark CEO Steven Paul. “This partnership represents a shared commitment to innovation, sustainability, and delivering safe, efficient fueling solutions for the aviation industry.”
