February 20, 2021 The greatest carbon sink on the planet: The Deep Ocean On this episode of the Changing Waters podcast, host Brad Warren speaks with Dr. Greg Rau of Planetary Hydrogen about using ocean chemistry to capture and store CO2, the toolkit for ocean carbon removal options, and why Greg thinks that the abiotic, natural chemistry of the ocean shows particular promise. Planetary Hydrogen is upending the global hydrogen market with the first scalable, truly carbon-negative form of hydrogen production. Their process converts greenhouse gases directly out of the air into an antacid for oceans damaged by climate change. This Ocean Air Capture (OAC) system is the first to be able to both remove the carbon dioxide that is causing climate change and to restore ocean chemistry. ....
Until recently, the concept of blue carbon attracted little attention outside academic and think-tank circles. We may be at a turning point, thanks to the actions of some forward-thinking businesses. ....
February 1, 2021 Forests of giant kelp, Macrocystis pyrifera, commonly grow in the cold waters along the coast of California.

Over the past few years, as companies have come under steadily increasing pressure to tackle climate change, nature-based solutions have emerged as a particularly exciting method for shrinking corporate carbon footprints. Investing in forests can be a win-win that both sequesters carbon and regenerates nature. That’s why one recent survey recorded almost $160 million spent on forest offsets in 2019. And a newer option, soil carbon, also is generating investment from multiple corporate sectors. ....
A burgeoning Ottawa cleantech firm that’s already landed Shopify as a customer for its “carbon-capture” technology that aims to reduce greenhouse gases is relocating most of its employees to Nova Scotia, the company said this week. Launched in 2019, Planetary Hydrogen has created a patented system that speeds up the natural process of removing carbon dioxide from the atmosphere. Dubbed SeaOH2, the system uses renewable electricity to split ocean water molecules into hydrogen and oxygen, a process known as electrolysis. Adding mineral salt to the electrolysis cell creates an atmosphere-scrubbing compound called mineral hydroxide as a waste product. The hydroxide binds with carbon dioxide, effectively “capturing” the gas while producing hydrogen – an increasingly sought-after green alternative to fossil fuels – as a potentially lucrative byproduct. ....
