Episode notes

On November 17th, 2023 the average global temperature was temporarily 2 degrees Celsius warmer than pre-industrialization, an event with ominous climate implications. To slow global climate change, we need to find ways to supercharge natural carbon removal processes like ocean alkalization, and do it in a way that is good for the planet. 

That’s exactly what this month’s Watt It Takes Guest, Ben Tarbell, Co-Founder and CEO of Ebb Carbon, is doing.

The team at Ebb is approaching carbon removal in a way that is both novel and as ancient as the ocean itself; integrating with existing facilities that process seawater, they use electrochemistry to remove acidity, and return the alkaline seawater to the ocean where it can then absorb more carbon.

Ebb has raised $23M, has a team of 40, and is deploying their carbon removal system. I spoke to Ben about his journey, from his childhood spent obsessed with building and engineering, to his career in solar, to prototyping the Ebb System in a bathroom-less empty warehouse, to opening Ebb’s first site and starting to meaningfully remove carbon via the ocean.
