Captura’s Post

Needless to say - we agree with Eric's conclusion! Erik Kobayashi-Solomon provides a good summary of Captura's technology and its potential in this article. I like his characterization of how we combine the best of nature and the best of technology to enable carbon removal at low cost and large scale #carbonremoval #directoceancapture

“By removing excess CO2 from seawater and enhancing the ocean's natural CO2-absorbing abilities, Captura aims to safeguard both terrestrial and marine ecosystems from the detrimental impacts of climate change while providing a scalable and cost-effective carbon removal solution. I get a kick out of imagining Captura’s systems chugging away on oil and gas platforms in the Gulf of Mexico while burying the captured carbon dioxide in the geological formations from which we now pull hydrocarbons.” Thanks to Erik from Forbes for the great Captura feature — click below to read the whole story. #CDR #CarbonRemoval #ClimateChange #Sustainability

Some interesting technology for #DOC - ‘Direct Ocean Capture’ which takes carbon out of seawater, allowing the ocean to take in more carbon from the air. The smart thing - just like #BlueCarbon - no chemicals or materials chucked into the sea. Who knows - there may be a day when Dr Ana Novak and Steve Oldham work together with complimentary DOC technology. #carboncapture #carbonreduction

Captura is one of two ARPA-E-funded projects driving progress in the relatively new field of Direct Ocean Capture (DOC).     Forbes recently spotlighted their promising DOC technology that leverages the oceans’ natural ability as a carbon sink to provide large-scale atmospheric carbon removal at a low cost.    Check out more from Forbes to see why Captura’s innovation is so promising: https://bit.ly/3SJWvy1.

Showing potential to change the carbon capture arena with a fundamental transformative technology approach.

Yet-Ming Chiang is a longtime professor at Massachusetts Institute of Technology and he’s also a co-founder of two of the most well-known climate tech companies right now: Form Energy, which is developing long duration energy storage systems, and Sublime Systems, which is commercializing cement made with electrochemistry. He's also just turned 66 and when he was 65, he co-founded three new climate tech companies, all of which are still in relative stealth mode: One in electric aviation, one in lithium extraction from hard rock resources and another involving the stimulation of geologic hydrogen. Learn how Chiang became an entrepreneurial powerhouse, in addition to being an academic, in the first of Cipher’s stories on undercover climate superstars.

The most fascinating long form output [book] from an LLM: Conscious Earth: Harnessing the Planet's Information Platform Revolution "At its core, the Earth's information processing capabilities stem from the complex interactions between its various systems - the atmosphere, hydrosphere, geosphere, and biosphere. These systems continuously exchange data through chemical, physical, and biological processes, creating a vast, interconnected network of information flow. The Earth's information processing system is akin to a global supercomputer, but one that operates on principles far more sophisticated and resilient than any human-made technology." https://lnkd.in/d8e7Ckkw #Earth #WardleyMaps #SDGs

What famous inventor’s water power tech ideas rarely made it past ink on a page? The answer might inspire you to compete in the #PowerAtSea Prize. In the first phase of the prize competition, all you need is a theoretically sound #MarineEnergy concept. Ideas in early stages of development are welcome—from a system, subsystem, or component that has not yet been developed to those that have had some previous work completed, even up to concepts in the prototype stage. The right idea could win you a piece of the $1.7 million cash prize pool. Find the trivia answer and more prize info: https://lnkd.in/g5anT_7y

We just proved that Ocean Alkalinity Enhancement is safe and effective… … at very small scale. Last week, Nature Communications Earth and Environment published a paper by scientists from Plymouth Marine Labs Applications detailing the results of our 2022 project - one of the first small scale Ocean Alkalinity Enhancement field trials. The key takeaways were: - Adding alkalinity (in this case, magnesium hydroxide) to wastewater converts the CO2 in the wastewater into dissolved carbonates and bicarbonates, thus reducing the amount of CO2 that would otherwise be emitted to the atmosphere. - This provides a proxy for the measurement of carbon removal in the ocean - The effect on ocean chemistry was barely detectable right at point of addition to the ocean (within 5 meters) and undetectable beyond that, - This confirmed the predicted, rapid dilution of the alkalized water below detection limits once discharged to the ocean, indicating the need for ocean modeling to estimate dispersal and any subsequent removal of CO2 from air. - All measured chemical effects stopped once the addition stopped, providing a clear “exit strategy” for the process This is a groundbreaking result, demonstrating that the process’ impacts, and therefore risks, are highly localized and temporary and clearly showing the positive effects of Ocean Alkalinity Enhancement. It provides strong confidence in our ability to incrementally and carefully scale up the technology. Planetary’s CEO Mike Kelland and Chief Ocean Scientist William Burt sat down to discuss the results and provide a bit of background on how the project came to be. You can also read through Dr. Steve Rackley discussion of the project and the results on our blog (https://lnkd.in/enbXPNn3). Congratulations to all the authors (Vassilis Kitidis, Steve Rackley, William Burt, Greg Rau, Sam Fawcett, Matthew Taylor, Glen Tarran, Malcolm Woodward, Carolyn Harris & Tim Fileman) on this incredible paper and thank you to our partners and collaborators at South West Water, PML Applications, Port and Coastal Solutions, Deltares, Royal HaskoningDHV, Coastal Science Ltd, Shopify, and many others. Appreciating as well the support of the Department for Energy Security and Net Zero GGR grant program. #cdr #oceans #mCDR #OAE #climatechange
