Volcano powered

I love that GNS is looking at supercritical geothermal generation.

They've commissioned Castalia to look at timelines and economic feasibility. It's looking good, from 2037, if we can get fast-track consenting - and if there aren't other substantial hiccups. 

NZ will need a whole lot more generation as carbon prices rise and folks shift away from carbon-intensive energy sources.

Great thing about geothermal is that it just runs. It doesn't care if the wind blows or the sun shines.

Waste heat can be used for other processes - like milk powder drying, or making wood pellets.

As reminder, here's Eli Dourado's piece from a couple years ago on the big-picture on this stuff.
