Diesel generator vs fuel cell at the forward edge
At a forward operating base, the diesel generator gives away your position and depends on a vulnerable fuel convoy. How a multi-fuel fuel cell changes the OPSEC and logistics math.
Off-grid & microgrid power without diesel
The diesel gen-set has a hidden cost — noise, emissions and a fuel convoy. How a multi-fuel fuel cell delivers clean, quiet, fuel-flexible power for off-grid sites, microgrids and OEM equipment.
Silent backup power for disaster response
Why disaster-response teams need power that is silent, safe to run indoors, and works on whatever fuel is available — and how a multi-fuel fuel cell delivers it.
Powering the dismounted soldier: silent, lightweight, multi-fuel
How a wearable multi-fuel fuel cell replaces the battery burden — a ~72-hour mission under ~2.7 kg, near-silent and low-signature, refuelable in the field.
