Hydrogen’s storage and transport difficulties make it impractical for large scale energy storage. Practical decarbonization requires either carbon-based fuels made from CO2 captured from the air, or a change to nitrogen based fuels. Nitrogen is much easier to capture from the air than CO2 is, so Starfire Energy favors nitrogen based fuels. Crude oil is not a particularly good fuel, but its derivatives like gasoline are. Ammonia is difficult to ignite, but we can use it to make blended carbon-free fuels to replace natural gas, propane, gasoline, diesel, and aviation fuel. Ammonia is not “a hydrogen carrier.” It is the practical basis for making better carbon-free fuels.
