H55 apparently has battery technology, it is related to ‘Solar Impulse’.
Harbour Air says the first battery it tried was so heavy the airplane had little range.
And that there were teething problems with MagniX equipment.
POC configuration first flew in 2019.
HA claim 30 minutes range with 30 minute reserve, their main run is Vancouver BC area to Victoria BC harbour. VMC operation only.
They have partners for charging stations, I am curious how quick as turnarounds have to be be short for economics.
The founder and boss of HA has a good reputation, but I wonder if he is up to this monster task, which I think is not needed unless it can reduce noise in Victoria Harbour.
Certification flight tests not expected until late 2023, there will be much ground testing earlier in that year.
HA is a large experienced seaplane airline, like Kenmore Air on Lake Washington, run well enough to have capital for turbine powered deHC airplanes. (The single Otter needs more power, turbines provide that, some small operators use a Polish radial installed by smart people in Ontario to get more power.)
