OptiFuel Systems, based in Beaufort, South Carolina, has signed a collaboration agreement with the Argentine Department of Transportation through Ferrocarriles Argentinos Sociedad del Estado (FASE) to upgrade 400 shunting and line haul locomotives from diesel to compressed natural gas (CNG) and/or renewable energy. natural gas power (GNR).

OptiFuel on 12 July it announced that it was developing modular repower kits for diesel locomotives and new locomotives of all lengths, power levels and track gauges. For the Argentina project, he said the kits will include OptiFuel’s zero-emission CNG/RNG engine modules in a hybrid configuration (1,500hp-4,500hp); locomotive control modules; and onboard CNG/RNG storage pods capable of carrying up to 2,000 diesel gallon equivalents (DGE) of natural gas. In addition, OptiFuel will supply motorized tender cars (3,000 hp) capable of carrying 11,500 CNG/RNG DGEs, and construct approximately 12-15 CNG service stations along the Argentine rail network, each with the ability to refuel a tender car in less than an hour. . The kits will be built in the United States and shipped to be assembled locally in Argentina.

OptiFuel’s zero-emission railway engine solutions are powered by its EPA-certified locomotive CNG/RNG engine rated at 0.00 g/bhp-hr for NOx, 0.000 g/bhp-hr for PM and negative CO2 using RNG, according to the company.

“OptiFuel is excited about the opportunity to provide zero-emission locomotives, tenders and refueling equipment to Argentina,” said OptiFuel President Scott Myers. “OptiFuel has developed and certified these technologies for rail because we believe there is a need for cleaner locomotives that generate increasing value for the world’s railways, railway customers and communities.

“Our transportation modernization plan is to develop more infrastructure across the country, and it’s also about innovative technologies, like this change in the energy matrix of our trains, to make them cleaner, more efficient, sustainable and cheaper,” said Argentina’s transport minister. said Alexis Guerrera.
