Tuaropaki Trusts' been involved in a wide range of joint ventures - from being a satellite internet provider to investment in 2degrees and hydroponic greenhouse production – they're even North Americas' largest wasabi producer here in Canada.
One of their main assets is a geothermal power station at Mokai near Taupo - I was lucky enough to get a look at it a few years back – where they’re now producing hydrogen in New Zealand's first megawatt-class green H2 production facility.
They don’t say exactly what gear they’re using, except that it’s a proton exchange membrane (PEM) electrolyser .
But their publicity picture’s worth a thousand words.
Behind the obligatory FCEV - a Mirai, refuelling from a 35/70 MPa H2H Gateway Refueler (the same refueler POAL's using, for now with H2 from BOC's green hydrogen plant in Glenbrook) is some neat equipment.
There's a 40' containerised Cummins/Hydrogenics Electrolyser, likely a HyLYZER-250 capable of producing 250 Nm3/h (normal m3 per hour), feeding a compressor/storage system, and high pressure H2 cylinder filling station.
The FCEV car's a bit of a red herring.
There's no way they're producing Hydrogen at such a low cost that - by itself - a vehicle on the lowest rung of the Hydrogen Totem Pole would be competitive with BEV's.
Assuming subsidies, a more viable use would be to start decarbonizing the tanker fleet that services over 100 suppliers within 80km of their Miraka factory - which they claim has one of the "lowest dairy processing carbon footprints in the world"
They've gone to a lot of effort to document the carbon emissions of their dairy suppliers, and with their new (ex Fonterra) CEO looking to "add more value" to their existing production there's got to be a high value niche in certified low carbon 'gate to plate' dairy production.

By Hydrogen Totem Pole I’m thinking of Michael Liebreich’s (producer of 2010’s alarmist “First They Ignore You” and founder of Bloomberg New Energy) visualization of a Hydrogen ladder..
I’d agree with his assessment of the upper and lower ends.
Electrification doesn’t work for fertilizer, steel, glass and cement because of the way they’re produced
At the other end their simplicity, conversion efficiency and diverse charging options for BEVs’ mean they’re by far the most likely future of light/medium transportation.
The positioning of industries on the centre rungs is more mobile – any of the looming advances in battery or H2 tech could push a bunch of them off towards either end.
It also ignores subsidies. With the addition of enough free money Hydrogen can temporarily fill any position on the ladder.
In some countries – like New Zealand – unlikely to produce our own batteries, and with lots of renewable energy potentially available for H2 production, regional trucking might be a rung higher.
Also for long-haul freight, hydrogen fuel cell trucks, particularly with ranges of more than 600km, and depending on the production cost of hydrogen, may be a viable path to GHG reduction.
