Heirloom

I’m so incredibly grateful to have met Noah and worked with him these last five years to grow Heirloom to what it is today. His intelligence, passion, and dedication to Heirloom and the climate is unmatched. We’re so fortunate that Noah will continue as a key part of the Heirloom team in this new advisory role – and I’m incredibly excited for his next step to help design policies, markets, and incentives to grow the carbon removal industry!

This is Shashank Samala, Co-Founder & CEO of Heirloom. Heirloom is scaling very fast through continuous innovation...and scaling quickly is exactly what we need right now. As he says “when you figure out how to give superpowers to limestone, all you need to do is get more limestone, build more trays, stack more trays vertically, and make those stacks taller.” Their aim is to remove 1 billion tons of CO2 from the atmosphere by 2035 and by the looks of it, they will get there. For more exciting innovations, watch Legion 44 currently available here: http://www.legion44.world    and while watching, you can remove CO2 with Heirloom as well as other visionary companies. Let's create a world that works, together ✨ 💪 🔥

📉 A Flat February for Durable CDR at 56K tonnes | CDR Monthly Recap - February 2025 📅 February saw a continuation of subdued activity in the durable carbon dioxide removal (CDR) market, with deals totaling just over 56,000 tonnes, following January's 67,000 tonnes. Here are some quick highlights from February: 📊 Over 56,000 tonnes of durable CDR were sold 🤝 Frontier buys 47,000 tonnes from Phlair for $30.8 million ✈ United Airlines' investment in Heirloom with right to purchase 500K tonnes 💨 TikTok and Two Drifters Distillery buy 6K tonnes from Climeworks 🌍 Carbon Removal Kenya (CRK) launches as Africa's first CDR industry association 🔗 https://lnkd.in/gvRfFMDt 📊 To uncover more such insights, read our latest edition of the CDR Monthly Recap featuring various CDR actors such as Exomad Green, Vaulted Deep, Oregon Biochar Solutions, and Charm Industrial.

Great insights from Vikrum Aiyer, Head of Climate Policy & External Affairs at Heirloom, on the regulatory and legislative opportunities to scale carbon dioxide removal in California and support the California Air Resources Board. #CDR #CCUS #CCS #California

As a kid growing up in India, I would gaze up at airplanes streaking across the sky, convinced they were the most magical machines in the world. I can still recall the thrill of my first flight—a journey that carried me not only into the clouds but also to America, a land of boundless possibility that I am now proud to call home. When we started Heirloom, we knew that as we bring down the cost of our Direct Air Capture (DAC) solution, we can start to help decarbonize aviation. Today, we made another meaningful step towards that goal: I’m excited to share that the United Airlines Ventures Sustainable Flight Fund, part of the largest airline in the world by fleet size, has partnered with Heirloom to scale Direct Air Capture. This partnership includes an agreement for the right to purchase 500,000 tons of carbon dioxide removal and an equity investment in Heirloom, building on our recent $150M Series B round in December 2024. The agreement enables The Fund to use the captured CO₂ for both permanent underground storage and as an input feedstock for the production of sustainable aviation fuel (SAF). This partnership validates DAC's critical dual role in helping aviation achieve Net Zero: as both a carbon removal solution and a key enabler of SAF production, addressing both sides of the Net Zero equation and creating two complementary commercial opportunities for our technology. Thank you, Mukul Hariharan, Andrew Shen, Andrew Chang and many others for this incredible partnership—the beautiful model airplane sits proudly on my desk :) Our blog post on why SAF + DAC can help achieve Net Zero https://lnkd.in/gdvFb26U Fast Company: https://lnkd.in/gcccS6PY Trellis:   https://lnkd.in/gzVye97e

🌍 Big News: Heirloom and the United Airlines Sustainable Flight Fund are joining forces to scale DAC as a critical tool to enable Net Zero aviation. ✈️ In addition to an equity investment in Heirloom – which builds on our recent $150M Series B round – the Fund also entered into an agreement for the right to purchase up to 500,000 tons of carbon dioxide removal (CDR), to be delivered for the production of sustainable aviation fuel or permanently stored underground. Why this matters: Aviation faces unique decarbonization challenges. The path to Net Zero requires both reducing emissions AND removing residual ones. While Direct Air Capture (DAC) is typically seen as just a removal solution, in aviation it's a powerful tool for both: 1️⃣ When used to produce SAF, our DAC CO2 can help create fuel that's up to 94% less carbon intensive than conventional jet fuel. Importantly, this fuel can be developed with CO2 that is ALREADY in Earth’s atmosphere, rather than extracting new sources of carbon from deep underground. 2️⃣ Since even the cleanest SAF will generate some CO2 emissions, our core CO2 removal capability remains crucial for achieving true Net Zero aviation. So how does this play out in the future? The answer is: we will need a lot more DAC to both generate cleaner fuels through SAF and remove those emissions that can’t be eliminated. Net Zero aviation requires a dual-pronged approach – and DAC can be a critical input to both sides. We’re proud to be partnering with United to move toward a future where Net Zero aviation is not just an aspirational promise but an operational reality. 🛫 Find out more 👉 https://lnkd.in/dEeKFVwE

Lessons from mobilizing $800M for carbon dioxide removal: So great to have Shashank Samala, CEO of Heirloom, join my “Climate Tech Startups and Investors” class at Duke University. Some key takeaways... Having experienced the impacts of climate change firsthand growing up in southeast India, climate change and its impacts on vulnerable populations have been on Shashank’s mind long before founding Heirloom. After moving to the US as a teenager, he studied mechanical engineering at Cornell, but maintained multidisciplinary interests in psychology, finance, and nuclear engineering. Shashank started his career at Square, before founding his first company, Tempo Automation. While successful, he never forgot his interests in climate change and helping others, and after becoming a self-taught expert in carbon removal, he founded Heirloom in 2020. Heirloom is now one of the leading CDR companies, having raised over $200M from investors including Lowercarbon Capital, Breakthrough Energy , MCJ, and Mitsubishi, and secured customers like Microsoft, Stripe, and Shopify. Heirloom’s direct air capture technology uses limestone to pull carbon dioxide directly from the atmosphere, helping move us toward a carbon-negative future. In addition to impressive venture funding, the company is part of a group that has also secured $600M in grant funding from the Department of Energy to build a million-ton scale facility in Louisiana that will create nearly 1,000 new jobs. An early mover in the CDR space, Shashank shared with students the importance of conviction, rapid innovation, and constant learning, as well as the mindset that has allowed him to found two successful companies in the last ten years.
