Back in March, I did a podcast on the possibility of using wind and solar electricity to decarbonize industrial heat, which represents fully a quarter of all human final energy consumption. The trick is to transform the variable energy from wind and solar into a steady, predictable stream of heat by using some form of heat battery.

The idea is that heat batteries will charge when renewables are cheap or negatively priced, around midday when all the solar is online, and then use the stored heat to displace natural gas boilers and other fossil fuel heat sources in industrial facilities.

Among other things, this vision represents a huge opportunity for renewable energy developers — industrial heat is effectively a brand new trillion-dollar market for them to play in. And they can often enter that market without waiting in long interconnection queues to connect to the grid.

Anyway, that episode, which I highly encourage you to listen to at some point, was with the CEO of a thermal battery company call Rondo. In it, I mentioned another thermal storage company whose technology caught my eye: Antora Energy.

Like Rondo, Antora is part of the broad “box of rocks” category, but its tech can do some things that, for the time being, no other thermal battery can do.

I don’t want to say much more here — discovery is half the fun — but I will say I’m as geeked about this technology as I have been about anything in ages. I’ve been thinking about it ever since I first heard about it three or four years ago. Now the company has launched its first commercial-scale system! So I’ve brought Antora co-founder and CEO Andrew Ponec on the pod to talk through how it works, what it can do, and how it could transform industrial heat markets.
