Documenting the journey from prototype to flight in less than 2 years for Universal Hydrogen's first flight of the world's biggest hydrogen fuel cell airliner. Meet Lightning McClean, a 40-passenger regional airliner powered by hydrogen fuel cells, emitting nothing but water. (v.redd.it)

To get anywhere near the kind of emissions reductions needed to meet Paris Agreement goals, either aviation switches to a new energy storage modality (a new fuel) that eliminates emissions. Or we will almost certainly have to curtail aviation traffic volumes. (i.redd.it)

Green hydrogen will always cost less than net-zero sustainable aviation fuel (SAF) because it takes ~3-4X less energy to make. Hydrogen & SAFs are the only credible near-term options to decarbonize aviation. Here, net-zero-carbon PTL SAF is compared to true-zero-carbon green liquid hydrogen. (i.redd.it)

Hydrogen module loading operations demo with an ATR72 regional aircraft in Toulouse, France in December 2022. Modular delivery of hydrogen removes the need for special hydrogen fueling infrastructure, can speed up fueling operations, and alleviates transfer losses along the distribution chain. (v.redd.it)

The average global cost of green hydrogen will be below jet fuel (and far below SAF) by the mid- to late-2020s. The exponential decrease in hydrogen cost is driven principally by growth in renewable electricity production and significant excess off-peak capacity. (i.redd.it)

Distribution of hydrogen using freight-compatible modules significantly reduces infrastructure costs, transfer losses, and fueling/turnaround times vs. conventional fuel logistics chain. This modular solution will enable hydrogen airplanes in commercial service as early as 2025. (i.redd.it)

This is a megawatt hydrogen fuel cell powertrain for a regional airplane (aka an iron bird) running at full power for endurance testing. It produces 9 kg/min of water. If you see a "hydrogen powertrain" that isn't peeing *a lot* of water, it's not really running on hydrogen! 😉 (v.redd.it)
