Great presentation, and interesting safety measures for handling hydrogen. GET has had issues with their filling station recently. Curious about the cost, and why not run the solar straight into a battery electric bus (or day storage battery) and skip all the gas release mitigation - but you still need a different fire suppression system to cope with a battery fire, typically a dunk tank. I assume these are fuel cell busses? Curious what the kWh per mile from the inverter is, how efficient are your electrolysers etc. etc. what are your capex, opex costs vs. LFP battery storage into an LFP bus - any promising battery swap or catenary charging systems you have also looked at? Every time I try and run the numbers, hydrogen as electrical energy storage for transportation doesn't seem to make sense - it never 'pencils out' - so I wonder what the exact stats you are getting are, have you solved the maintenance problems with the dispensing equipment that some others see, etc. etc. Would be good to see a side by side comparison with your battery bus - I assume you are also running battery busses from your solar too as a comprehensive alternative energy trial. I do understand kWh per mile is not the only metric to measure a bus by, but I'm nerdy about the numbers.
