This startup wants the $80-billion U.S. railroad industry to switch from diesel to batteries
Skulle dessa superbilliga natriumvagnar kunna användas för att köra till Köpenhamn utan att behöva krångla med den danska järnvägens avvikande spänning?
Batterirevolutionen fortsätter med så kallade mikronät. Tyska Siemens är naturligtvis med på tåget, men den amerikanska uppstickaren Voltify har andra tankar:CNBC skrev:Voltify’s VoltCars — essentially sodium-ion batteries on wheels — are designed to connect to existing freight locomotives.

Kessel knew the renewable energy market well, having co-founded Doral, a firm that owns and operates dozens of solar energy farms in the U.S. and Europe. He calculated that the six largest freight railroad companies in the U.S. — including Union Pacific and CSX — were collectively spending more than $11 billion a year on diesel, a figure verified by CNBC. Union Pacific, for example, spent almost $2.5 billion on fuel in 2024, per its annual report.

So Voltify spent about a year working on an algorithm that could forecast the energy demands of trains “in every route,” Langer said, and the company is also building its first solar-powered energy microgrid that Langer said is on track to be finished by the end of the year. “Our calculations show that a network of these microgrids could eventually power all trains in North America,” Langer told CNBC in an email. Voltify estimates that to do so would require 1,400 microgrids.

Siemens Mobility has sold more than 400 diesel-electric Charger locomotives in North America, and in June launched its battery-electric train, the Charger B+AC, selling 13 to the New York’s Metropolitan Transportation Authority and Metro-North Railroad.
