Nimbus Power Systems:
Fuel Cells for the Long Haul
With 50+ years of heavy-duty fuel cell experience, we design and deploy engines for heavy-duty applications.
NIMBUS300 for Heavy Duty Trucks
Rethinking Heavy Duty Fuel Cells
Proven Durability
Our patented cell technology enables a 30,000 hour operating life. No major overhauls, cell, or stack replacements required.
Diesel-like Operability
Our systems are one-to-one diesel replacements. Run them in any climate, on any drive cycle, without the need for batteries to augment traction power.
High Efficiency
Nimbus' system architecture maximizes cell performance and eliminates the need for a DC/DC converter -- reducing cost, weight and volume while drastically improving efficiency over the entire life of the system.
Energy Dominance
Hydrogen is the strategic choice for heavy-duty transportation. It taps multiple feedstocks (natural gas | nuclear‑powered electrolysis | renewable-powered electrolysis), delivers long‑range, fast‑refueling energy for trucks and buses, and allows the space program to leverage fuel‑cell industry R&D and supply chains while capitalizing on their common use of liquid hydrogen.
Diesel engines have powered the heavy-duty market for over 100 years. And with good reason! Diesel engine technology proved itself as a durable, reliable, low-cost solution to vehicle power generation.
