The 120 kW fuel cell system, the S1200, builds on Loop Energy’s existing technology, to provide an additional efficiency gain of 20% when it generates electricity. The S1200 is designed to deliver up to 60% in net system efficiency (Net system efficiency includes power consumption of the air compressor, coolant pump, and other system components;, the gross design efficiency of the underlying Loop fuel cell stack is up to 65%), this efficiency enables an electric vehicle powered by a Loop Energy fuel cell to deliver up to 54% (Assumes a 90% drivetrain efficiency of the electric vehicle) fuel to wheel efficiency compared to the typical fuel to wheel efficiency delivered by a diesel engine powered vehicle of 20% to 25% (Hjelkrem et.al., Estimation of tank-to-wheel efficiency functions based on type approval data, Applied Energy 276 (2020)).
Loop Energy has achieved this efficiency gain because of its patented eFlow™ fuel cell architecture. Specifically, Loop Energy uses a signature trapezoid plate with narrowing channels for its bipolar plates, which increases gas velocity down the plate to deliver superior performance for fuel efficiency, and power output.
For fleet managers, operators of commercial vehicles and the wider hydrogen infrastructure market, that means less hydrogen fuel used per kilometre, lowering the total cost of ownership (TCO) of hydrogen-electric commercial vehicles.
The S1200 is delivered as a complete fuel cell system which simplifies and quickens integration for vehicle OEMs, and makes it a ready-to-adopt solution for heavy-duty transportation and power system applications.
