Green Road brings Hultsteins’ TRU generator to US

June 12, 2024
Renewables specialist partners with Swedish manufacturer to distribute Ecogen2 hydraulic-drive generators for transport refrigeration units across the Atlantic.

Hultsteins recently teamed up with U.S. renewables specialist Green Road Energy to bring each company’s carbon and cost saving transport solutions to both sides of the Atlantic.

Based in Lakeland, Florida, Green Road Energy is a designer and producer of energy preservation systems that harness wind, solar power, and vehicle-generated electricity to provide low-cost clean energy for auxiliary systems on trucks and trailers.

The company’s TAG (turbine auxiliary generator) system, which is mounted to the trailer chassis and uses wind-turbine technology, bypasses the alternator and engine to generate electricity for tail lifts, fridge units, lighting, and auxiliary batteries. The TAG system reduces diesel fuel consumption and emissions as it constantly generates renewable wind energy, displaces carbon-intensive power sources, and brings operating costs down, Green Road Energy reported.

“Both these energy-efficient systems are easy to retrofit and use inexpensive, basic technologies to reduce running costs and slash harmful emissions,” Graham Usher, Hultsteins U.K. managing director, said in a news release. “Ecogen is widely used in Europe and the TAG system is quickly making a name for itself in the U.S.

“Now, with this new alliance, operators on both sides of the water can benefit from these innovative, non-polluting, and affordable alternatives to diesel power.”

Trailer refrigeration—without the diesel

Designed specifically to bypass the diesel engine on all conventional trailer refrigeration units, Hultsteins’ Ecogen2 is a slim-fit, hydraulic-drive generator that plugs in to any make of transport refrigeration unit (TRU) to supply a constant 400-volt, three-phase electrical power, even at idle, Hultsteins said.

Connected to the tractor’s PTO, Ecogen2 draws power directly from the tractor engine. The energy produced powers the trailer’s refrigeration unit on electric standby during transit, reducing CO2 by around 90%, DPM by 90% and NOx by around 400%.

U.K. foodservice provider Reynolds Logistics, now in its third year with Hultsteins, recently placed a third order for Ecogen2, bringing the total to 15. The company also is taking two TAG systems to test on its temperature- controlled rigid units.

 “I had the opportunity to see the Ecogen2 in action and was thoroughly impressed by its innovative approach to sustainable refrigeration,” added Brian Arnold, Green Road Energy chief technical officer, who recently visited Hultsteins in England. “Recognizing its potential to transform the transportation industry, I was motivated to bring this cutting-edge technology to the United States.

“After successful negotiations, Green Road Energy is now proud to be the official distributor of Ecogen2 in America, offering fleet operators a powerful solution to enhance efficiency and reduce environmental impact.”
