See how fuel, water recovery and fuel cells work together inside the POWER POD.
How the POWER POD works
The POWER POD reforms a hydrogen carrier on-site, then feeds the hydrogen to a fuel cell to generate electricity.
Hydrogen carrier
LPG or another supported fuel.
Reformer
Reacts the fuel with steam to release hydrogen.
Hydrogen
A hydrogen-rich gas flows to the fuel cell.
Fuel cell
Hydrogen reacts with oxygen from the air.
Electricity
Powers a load or charges batteries.
Steam feeds the reformer.Recovered water is reused within the system.
Hydrogen from LPG + steam
One LPG cylinder. Around 30 hydrogen cylinders.*
Using steam reforming, a 48 kg LPG fill produces approximately 21.85 kg of hydrogen on the calculation basis below.
1 × 48 kg LPG cylinder≈30 hydrogen cylinders*

The POWER POD reforms the hydrogen carrier with steam to produce hydrogen for the fuel cell. This comparison includes hydrogen contributed by the steam, rather than only the hydrogen chemically bound in the LPG.
Example calculation & cylinder reference
HYENA’s supplied steam-reforming basis: 0.4552 kg of hydrogen per kg of LPG. A 48 kg fuel fill × 0.4552 = 21.8496 kg of hydrogen, rounded to 21.85 kg.
Hydrogen cylinder example: 50 litres at 200 bar, with approximately 0.74 kg of hydrogen per cylinder. 21.8496 ÷ 0.74 = 29.53 cylinders, rounded to about 30.
The cylinder reference uses a supplier-listed gas content of 8.8 m³ at 15°C and 1 bar, converted at approximately 0.084 kg/m³. Cylinder counts vary with size and filling pressure. This is a hydrogen-quantity calculation, not a comparison of electrical output or runtime.
The use of existing LPG infrastructure makes HYENA’s POWER POD deployable now.
This is a huge advantage over our competitors using non-distributed fuels, such as methanol or ammonia, specifically in developing countries.

Looking ahead
A pathway to lower-carbon fuels.
Fuel flexibility creates opportunities to use lower-carbon alternatives as their supply develops.
LPG contains carbon. It can also be produced synthetically using captured CO2 and renewable hydrogen—an approach known as power-to-X. These “green gas” pathways offer a route to reducing the carbon footprint of fuels supplied through existing infrastructure.
