At last week’s ClimateTech Coffee 🚲 Bryan White and I were joined by Kimberly Gilbert, PhD to hear about her work on Carbon Neutralization and Ocean Storage (CNOS) through her company pHathom. Here’s a recap: The ocean naturally absorbs CO2 over time, but we’ve added so much that the ocean has become increasingly acidic. Ocean pH has dropped from 8.2 to 8.1 globally over the last hundred years, and as pH drops it becomes harder for coral-based organisms to form shells. To combat this, Ocean Alkalinity Enhancement (OAE) is an intervention that both reverses ocean acidification and removes CO2 from the atmosphere. Challenges with traditional OAE: - When you add the alkalinity into the ocean, it spreads out. It’s hard to measure the change in pH. - You don’t know exactly when the extra CO2 will be absorbed. Modeling and measurement companies are trying to help with this problem. Advantages of CNOS: - Co2 is captured directly at a coastal power plant or refinery, and then the concentrated Co2 is pumped into water that has limestone (and/or other alkaline materials) in it. - This means the Co2 is dissolved onsite and the pH can be equilibrated onsite, which makes accurate measurement more feasible. Factors that affect progress: - We’ll start seeing more companies enter in this space as the chemistry and its impacts are better understood and seen as safe - Local and national permitting are a huge bottleneck - On the international permitting level, the London Protocol has a blanket ban on ocean geoengineering for anything except for research. There were good reasons for doing that, but it’s unclear who decides when that can change and the circumstances under which the ban is lifted. (Note: pHathom is not doing geoengineering; it’s doing water treatment on-site and releasing it back as ocean water) Open questions for the category/technology: - Can they come up with enough low-cost alkalinity sources, and get them in a way that doesn’t cause additional environmental damage or Co2 emissions? - This approach will require pumping a lot of water. How much will that cost and how can the cost be driven down? - Putting 100 plants’ worth of bicarbonate into the ocean is likely fine for ocean health relative to the climate benefit, but what is the point where the tradeoffs cross over? Some groups doing good work in this space: [C]Worthy Carbon to Sea Initiative University Research: UC Santa Barbara, University of Tasmania, GEOMAR, Dalhousie University, Scripps Join us for the next one in May!

The ocean plays an essential role in regulating our environment. This natural #carbonsink already absorbs around 30% of our annual emissions, and one company has found a way to boost this capacity even further 🌊 LA-based Equatic.tech's groundbreaking process accelerates the ocean's carbon cycles. At scale, this could prove to be a game-changer in addressing the climate and biodiversity crisis. Equatic's first full-sized plant, in development for 2026, is set to eliminate 300 tonnes of CO2 and produce 10 tonnes of green hydrogen daily. Gaurav N.

A recent article in Carbon Pulse highlights the potential of global forests to sequester around 20 years' worth of fossil fuel emissions, identifying a deficit of 226 billion tonnes of CO2. It highlights significant carbon capture possibilities in low human footprint regions, urging protection against climate adversities. Utilizing advanced data analysis, it stresses on safeguarding existing forests and reforestation. The study and it's authors emphasize a holistic approach, considering biodiversity and socio-economic factors, cautioning against viewing forests merely as carbon offset solutions, and advocating community-driven conservation for sustainable carbon capture and biodiversity benefits. This resonates so much with me personally as well as the work that we at the Boston Consulting Group (BCG) are doing with the Southeast Asia Climate and Nature-based Solutions (SCeNe) Coalition. Will McGoldrick, Martin Callow, Raghunathan R, Edwin Seah, Daniel Oehling, Brendan Board and Min Ai Kok - looking forward to continuing our work together on fostering triple benefits NBS projects in Southeast Asia!

Extremely interesting. This analysis seems to prove that there is no single priority ecosystem and that targeting conservation strategies towards that environment can achieve a meaningful goal for the planet. Rather, it proves once again that the diversity of ecosystems and their interrelated functions is the mechanism that ensures life on the planet and resilience to major environmental crises.

Did you know that under extreme conditions, some bacteria can turn CO2, a greenhouse gas, into rock? This process is known as carbon mineralization and it's capturing the attention of scientists and environmentalists alike for its potential to help combat climate change. Researchers at the South Dakota School of Mines and Technology have isolated a species of Geobacillus #bacteria from a compost pile in Washington state, known for its resilience to high temperatures and pressures. These microbes can rapidly convert CO2 into rock, potentially offering a more durable method for storing this greenhouse gas underground in places like depleted oil and gas reservoirs. At the Sanford Underground Research Facility, a set of naturally occurring microbes was found that can eat CO2 gas and solidify it through carbon mineralization. This process, typically slow in nature, taking 7 to 10 years, can be significantly sped up with these microbes, transforming CO2 into solid rock in just ten days under the right conditions. This discovery was made possible by a National Science Foundation grant and could revolutionize the way we approach carbon sequestration (Sanford Underground Research Facility). An essential component of this rapid mineralization is an enzyme produced by the bacteria, known as carbonic anhydrase. This enzyme helps reduce the acidity of the solution that CO2 is dissolved in, allowing magnesium and calcium released from the rock to form carbonate minerals. While surface-dwelling microorganisms and even humans produce this enzyme, it's rare for it to be effective in the extreme conditions found deep underground. The research into these extremophile microbes could pave the way for injecting them into actual storage wells to sequester CO2 more efficiently (My Blog). The implications of this research are profound. Not only does it offer a new avenue for reducing atmospheric CO2 levels, but it also highlights the incredible adaptability of life forms to extreme environments.

If we lose them, we will lose them forever. The world cannot afford losing some ecosystems and geo-structures that are crucial for the climate stability. They have formed in thousands of years and we risk losing them in just few decades. The picture and report show how they are highly concentrated and hence how vulnerable they are.

The ocean has long taken the brunt of the impacts of human-made global warming, says United Nations Climate Change. As the planet’s greatest carbon sink, the ocean absorbs excess heat and energy released from rising greenhouse gas emissions trapped in the Earth’s system. Today, the ocean has absorbed about 90 percent of the heat generated by rising emissions. As the excessive heat and energy warms the ocean, the change in temperature leads to unparalleled cascading effects, including ice-melting, sea-level rise, marine heatwaves, and ocean acidification.

📣📰: New research shows that microplastics in our oceans are affecting the sea’s ability to absorb carbon.🚨🌎 ‘The ocean absorbs a significant amount of the carbon dioxide we produce, partly through "marine snow" — organic matter that sinks to the ocean floor, taking carbon dioxide with it. According to Earth.com, a study by researchers from Northeastern University and the University of New Hampshire has revealed that microplastics are disrupting the formation and sinking of "marine snow," a crucial process for carbon sequestration. The tiny plastic particles increase the buoyancy of marine snow, slowing its descent to the ocean floor and thereby reducing the ocean's efficiency in "sucking up" carbon dioxide from the atmosphere.’ 📰READ THE ARTICLE: https://lnkd.in/eDTVHSnf 📰READ THE RESEARCH PAPER: https://lnkd.in/edXYGe4D #Microplastics #Microfibres #ClimateChange #CarbonSequestration #GlobalWarming #Sustainability #OceanConservation #OceanPollution #CleanSeas #CleanerSeas
