Trainsmission
Technology
We discharge trainloads of electricity in as little as two hours.
Battery railcars charge where power is cheap, move over the freight network that already exists, and deliver roughly 2 GWh per unit train — straight to the grid or behind the meter. No new transmission line. No interconnection queue.
How it works
01
Charge at the source
Distant generation assets charge the iron-phosphate batteries integrated into each railcar — at 0.25C on Gen.1 and 0.5C on Gen.2, over a 1,500 VDC bus.
02
Move on existing track
The loaded train runs over the freight network already in place — the same corridors that once carried more than 800 daily coal trains between 9,000 mines and 1,800 power plants.
03
Discharge on arrival
Proprietary automated equipment connects the train at the railhead. Every railcar discharges simultaneously, direct to the grid or to behind-the-meter loads, in as little as two hours.
Two charge / discharge systems
The Trainsmission Company has two charging and discharging systems to meet your specific energy application. The receiving railhead can sit miles from the actual load — power is routed the rest of the way over conventional cabling, at a voltage configured for the site.
DC system — from 1,000 VDC
AC system — up to 34,500 VAC
All railcars discharge simultaneously
Railhead may sit miles from the load
Energized in as little as 12 months from financing
Equipment
Both systems are built and have been demonstrated. Gen.1 discharges over a DC bus; Gen.2 adds an AC connection for higher-voltage delivery. Each is shown below as a rendering of the connection sequence and as a recording of the equipment running.
Specifications
Gen.1 is in manufacturing now at 18.8 MWh.
Gen.2 follows at 20+ MWh. Full drawings and specifications for both are on the railcar specs page.
