Ephemeral Carbon

Groundbreaking findings in a pre-print from Hourglass Climate and lead author Emilia Jankowska, based on Vesta, PBC's field trial, show no significant negative impacts on oysters exposed to olivine in the world’s first coastal enhanced weathering demonstration. Oysters at both control and olivine-treatment sites grew normally, and nickel levels remained well below the US FDA safety threshold—and consistent with global natural ranges. Oysters are ideal test organisms for this research due to their sensitivity to alkalinity, filter-feeding habits, ability to accumulate metals, and commercial importance. Since trace nickel release has long been a chief concern about marine carbon dioxide removal (mCDR) with olivine, these real-world results add to the accumulating body of evidence that deploying olivine in coastal settings can be done safely. Of special note: nickel concentrations in seawater never exceeded recommended US EPA water-quality criteria throughout the trial. This real-world demonstration represents an important step in advancing mineral alkalinity mCDR solutions that aim to fight climate change while protecting marine life.

Are open system carbon removal methods inherently less permanent than closed systems? A recent white paper by Boston Consulting Group (BCG) suggests that open systems, like Coastal Enhanced Weathering, fall short of closed systems in terms of permanence. At Ephemeral, we respectfully disagree. Permanence has nothing to do with whether a system is open or closed—it’s about how long carbon stays sequestered. In fact, some open system approaches, like Ocean Alkalinity Enhancement, are among the most permanent solutions available. We’ve broken down the differences between open and closed systems, their unique advantages, and why we chose an open system process despite the challenges. Read our full response here: https://lnkd.in/gxbHaXaJ We’d love to hear your thoughts! Do you see open and closed systems as complementary or in competition?

We’re thrilled to welcome Dr. Bita Sabbaghzadeh to the Ephemeral Carbon team as our new Marine Biogeochemist! Prior to Ephemeral, Bita’s research provided critical insights into air-sea gas exchange, a process which underpins all marine carbon dioxide removal solutions. In a Nature Geoscience study, she and her colleagues revealed how biologically derived surfactants—natural compounds concentrated in the ocean’s surface microlayer—can suppress CO? flux rates by up to 32% in certain regions. Her research showed that these surfactants reduce turbulence at the air-sea interface, significantly altering the ocean’s role as a carbon sink. This work underscored the importance of incorporating surfactant effects into global carbon flux models and laid the groundwork for more accurate estimates of air-sea CO? exchange. In her work on the EVAR Project, Bita studied the variability of CO? and non-CO? greenhouse gas fluxes in the Eastern South Atlantic, particularly in the Benguela upwelling system. Her research examined seasonal and shorter timescales to determine whether the system acts as a greenhouse gas source or sink. This work has been instrumental in expanding knowledge of the ocean’s role in regulating greenhouse gases beyond CO?, improving global flux estimates, and informing climate policy. At Ephemeral, Bita will bring her expertise in ocean carbon processes to develop scalable, accurate MRV (Monitoring, Reporting, and Verification) methods for our Oceanic Enhanced Weathering (OEW) deployments. Her contributions will help unlock the immense potential of this low-cost, durable, and scalable technique to combat climate change. Welcome aboard, Bita!

Setting up for our first Ephemeral company holiday party! Happy holidays from the Ephemeral Carbon team, see you all in the New Year! ??

The New York Times recently highlighted the growing importance of carbon removal technologies in the fight against global warming, calling it the 'New Climate Gold Rush.' As the world grapples with rising temperatures and the need for actionable solutions, carbon capture stands out as a pivotal tool for reducing atmospheric CO? levels and achieving net-zero goals. More than 1,000 major companies have pledged to eliminate their carbon emissions over the next few decades—will yours be one of them? #CDR #ClimateAction #NetZero

We are thrilled to welcome Dr. Q Wu to Ephemeral Carbon's scientific team! Q joins us as a Senior Research Scientist and will focus on sediment and reactive transport modeling for our offshore olivine deployments. We’re excited to have Q on board as we advance our mission to restore our planet’s climate and ocean. #CarbonRemoval #ClimateRestoration #Research #EphemeralCarbon #MarineScience

Here are some key takeaways from our CEO, Josh, reflecting on the exciting advancements shared at #AGU24 last week!

We had a great time at #AGU24 this week! The Ephemeral Carbon team enjoyed engaging with the community, exploring posters, attending talks, and advancing the conversation around carbon removal. It was exciting to connect with others who share our commitment to addressing climate challenges and ocean-based carbon removal. We’re proud to put our name out there and are looking forward to what’s ahead! #mCDR #CarbonRemoval #ClimateAction #OceanAlkalinityEnhancement

We're excited to share that Ephemeral Carbon has been selected as a recipient of the VO-5 U.S. Department of Energy (DOE) Voucher! This funding will support our progress in marine carbon dioxide removal (mCDR)—a crucial solution in the fight against climate change. In collaboration with 350Solutions, we’ll be validating key frameworks for carbon management technologies: - Techno-Economic Analysis (TEA) - Life Cycle Assessment (LCA) - Measurement, Reporting, and Verification (MRV) These validations are essential for tackling the biggest challenges in mCDR, like how to accurately measure and track carbon removal in ocean systems, ensure cost-effective deployment, and scale solutions to the gigaton level. Thanks to this support, we’re one step closer to unlocking the ocean’s immense potential to store carbon for hundreds of thousands of years. #CarbonRemoval #MarineCDR #mCDR #ClimateAction
