Brineworks: From “Magic Box” to Upgraded Suit | CO₂ + H₂ for E-Fuels

What if the climate mission stays the same, but the technology gets a better suit? In this episode, Lydia catches up with Joe Perryman from Brineworks to unpack how the company evolved from its earlier ocean-based concept into a land-based system built around a closed saltwater loop. Brineworks now produces two key feedstocks for synthetic fuels: sustainable CO₂ and green hydrogen. But this conversation is about more than one company’s technical upgrade. It is also about a broader shift in climate tech: from “we should do this because it’s sustainable” to “it’s sustainable, and it can increasingly make sense as good business too.” We cover: why Brineworks moved away from the ocean-based setup how the land-based system works in plain English the closed-loop saltwater design why CO₂ + H₂ matters for e-fuels where Brineworks sits in the value chain and why cheap, intermittent renewables change the economics As Joe puts it: “It’s sustainable, so we’re gonna do it because it’s the right thing… but it’s also now just getting very cheap.” Explore more: Brineworks: brineworks.tech Bite-Size Climate Tech / Day Zero Production: dayzeroproduction.com/bite-size-climate-tech Visual note: The CLI animated sequences are simplified educational illustrations based on Joe’s explanation.
