🌊 COVE’s #OceanConnector on #MarineCarbonDioxideRemoval (mCDR) is taking place TODAY from 4:00 p.m. – 6:00 p.m. AST at our facility. 🔗 If you still need your ticket, register here and be ready to present it upon arrival: https://lnkd.in/eJgSaUuZ The mCDR panel will be hosted by Levi Morrison, Director | Innovation at COVE, featuring leaders shaping the future of mCDR in Canada: 🔹 Paul Richards, Senior Corporate Advisor, Infrastructure | Invest Nova Scotia 🔹 Dr. Will Burt, VP, Science & Product | Planetary and Adjunct Professor | Dalhousie University 🔹Eric Siegel, Chief Innovation Officer | Ocean Frontier Institute Join us to hear how mCDR technologies are driving #MarineInnovation, supporting climate action, and creating new opportunities for Atlantic Canada’s #MarineEconomy. A special thank you to our founding partner Irving Shipbuilding for their continued support of the Ocean Connector series.

At #COP30, we were part of an important conversation on methane- the super pollutant driving near-term warming and demanding immediate, scalable action. Our CEO Mike Kelland joined leaders from across the climate innovation space to dig into what it will take to meaningfully cut methane emissions: real-time leak detection, ultra-low-cost monitoring, next-generation capture pathways, and solutions that meet communities and industries where they are. But we remove carbon, so why are we talking methane? Glad you asked: At Planetary, we see methane action and durable carbon removal as complementary parts of the same mission: deploying science-led, scalable climate solutions that protect people and ecosystems today while building long-term planetary stability. Thank you to the XPRIZE team for convening this critical discussion, and to all the partners pushing for bold #action now.

Funding opportunity for ocean alkalinity science, deadline Jan 9 (take a look Jason Qin, Faith Qin, Gabriel Boyd!) #OAE Planetary, Carbon to Sea Initiative https://lnkd.in/eU4AYGeM

These shells were grown under different conditions. The ones on the left, exposed to more acidic water, are lighter and more translucent than those on the right. As seawater absorbs more CO₂, it becomes more acidic, making it harder for shellfish to form the calcium carbonate that builds their shells. In Atlantic Canada, this threatens marine life and the fisheries that depend on it. At Halifax’s Tufts Cove, Planetary is evaluating how ocean alkalinity enhancement (OAE) influences local ocean chemistry. By adding pre-dissolved alkaline minerals to coastal waters, Planetary’s system slightly raises pH, restoring the ocean’s natural capacity to absorb CO₂ from the air. The CO₂ reacts with the alkalinity to form bicarbonate—carbon that remains safely stored in the ocean for thousands of years. The Tufts Cove pilot recently delivered the world’s first verified OAE carbon removal credits and recorded a measurable local increase in pH near the discharge site. Planetary is now working with Dalhousie University to quantify the benefits of this approach for marine calcifiers like oysters, shrimp, lobsters, and crabs. 

I used to think engineered carbon removals were overhyped. Now I realize they’re essential. Last week, I understood how Engineered CDRs (Carbon Dioxide Removal) fit into the net-zero equation — and why nature-based solutions alone won’t get us there. To be honest, I was a bit skeptical at first. I wasn’t sure if these technologies actually worked or if they were just a way for companies to avoid cutting their own emissions. Direct Air Capture felt like a billionaire toy: expensive, flashy, disconnected from real impact. But after diving deep into these technologies, I came out genuinely impressed. 🌱 Biochar 🌱 Turns agricultural waste or other biomass into a stable form of carbon that stays locked away for centuries, while improving soil fertility and structure. It enhances microbial life, water retention, and nutrient availability — which is why it should be part of every farm’s soil strategy 🌾💛 It’s also one of the most ready, scalable, and low-risk CDR solutions out there 👑 Challenges remain — sustainable feedstock supply, logistics from the Global South, and consistency — but innovators like Exomad Green (Bolivia) and NetZero (Brazil) are already building solid models to scale it 💪 🪨 Enhanced Weathering (EWR) 🪨 Finely crushed silicate rocks (a mining by-product) are spread on farmland, where they react with CO₂ in the air and form stable carbonates underground 😯 Simple chemistry, powerful results. Beyond capturing carbon, EWR also helps regenerate soils by replenishing essential minerals and reducing acidity. The barriers: complex monitoring (2–5 years of field data) and farmer adoption, since it competes with traditional aglime. Still, companies like Lithos Carbon, Eion Carbon, InPlanet and Undo are proving it can work 👏👏 🌊 Ocean Alkalinity Enhancement (OAE) 🌊 This one truly amazed me! I’ve always felt the ocean is underrepresented in climate discussions, even though it absorbs about a quarter of global CO₂. But that absorption has made it increasingly acidic, threatening marine ecosystems. OAE literally reverses that process — adding alkaline minerals that neutralize acidity, create stable bicarbonates, and boost the ocean’s natural capacity to absorb CO₂ while protecting marine life 🐳 🦈 🐠 It’s still early — MRV and social acceptance are major hurdles — but pioneers like Planetary, Ebb Carbon, and Limenet are leading the way 💙💙 💡 If you want to explore more CDR solutions CDR.fyi 's platform is the place to go https://www.cdr.fyi/ I finished the week feeling energized and hopeful. Thanks, Hannah Calloway and Eileen McGurty, Ph.D. at Climatebase for such eye opening lectures 🙏 Humans are smarter and more capable than we think. The tools exist — we just need more people building and scaling them. The climate space is huge!

Really thoughtful piece from Fondriest Environmental, Inc. Environmental Monitor on how researchers in Halifax Harbour are using buoy systems to monitor the plume, chemistry, and CO₂ uptake potential of ocean alkalinity enhancement (OAE) in real time.
