Thank goodness you’re here!
Thanks a lot, this clarified things again.
We already agreed in the Hyzon thread not to compare apples and oranges, but I thought I’d do it anyway.
So, Hypoint:

HyPoint vs. existing hydrogen fuel cell systems
The system offers many additional advantages over traditional hydrogen fuel cell systems:
- 3x higher specific power (2,000 W/kg vs. 700 W/kg) – with plans to increase to 3,000 W/kg by 2024
- Climate independence (easy to cool, doesn’t use water, impervious to freezing)
- Lower hydrogen quality requirements (CO: 1% vs 0.0001%) → lower operational costs
- Simpler design: fewer parts → higher reliability, lower acquisition and maintenance costs
- Suitability for large scale integration with manned and unmanned airborne applications
- More reliable under overload (important in emergency case)
So, do I understand this correctly now:
https://hyzonmotors.com/zeroavia-places-evaluation-order-for-hyzon-motors-high-power-density-fuel-cell/
ZeroAvia selected Hyzon’s fuel cell stack for this evaluation due to its industry-leading power density. As confirmed by leading technical certification provider TUV Rheinland, Hyzon’s Gen3 fuel cell stack achieves a volumetric power density above 6.0 kW/liter and gravimetric power density more than 5.5 kW/kg, well above industry averages. These factors are critical in aviation to minimize weight while providing sufficient power for the desired performance.
So this Hypoint has indeed made a cell for aviation with 2kW/kg and plans to develop 4kW/kg by 2024, or do I need to learn to read better?
