When the HYPER lab was founded in 2010, our inaugural project here in the heartland of the aerospace industry, was to build the first liquid hydrogen fueled drone by a university team. Genii, short for the Latin Pondus Hydrogenii (a.k.a. ph, the hydrogen potential) was designed for a 1 kW proton exchange membrane fuel cell and lithium ion batteries. Our reasons for aerospace as a founding lab focus are clear: 1. Washington State is the #1 aerospace state in the US. 2. Aerospace is one of the most challenging sectors to decarborize (as described in this 2020 McKinsey report). 3. The weight and power curves of hydrogen fuel technologies shown in the preceding section are close to ideal for typical aircraft. 4. The solid state drive train of hydrogen fuel cell technologies is more reliable, quieter, has lower thermal signature, and higher excess power available for instruments than other technologies. 5. The logistics of hydrogen fuel allow for production on the deck of aircraft carriers or in other remote locations as long as water and electricity are available. » More ...
