Jet fuels have specific energy of 12,000Wh/kg vs. 250Wh/kg for batteries.
The absolute minimum to enable aviation is 2000Wh/kg .
DME (Dimethyl Ether), is a synthetic fuel derived from methanol (specific density 7,889Wh/kg), and tomorrow from renewable methanol). It is the solution for carbon-neutral net-zero emissions well to wing aviation.
We develop 50W to 30kW fuel cells based on methanol natural gas or DME that fit the needs of drones, air-taxis, eVTOLs, and aircraft auxiliary power systems.
Drones with methanol (or DME) can fly
for 12hrs vs. 30 mins for battery ones.
3x to 10x the range and autonomy of current battery solutions
Refill time and flexibility
The vehicle/drone can refill in three minutes vs. hours required for recharging.
Significant net weight reduction and payload weight increase.
Extreme weather operation
Li-ion batteries do not charge or discharge effectively during wintertime (very cold temperatures) and have shortened life in hot weather.
