Alt Carbon Secures $12 Million Seed Funding to Scale Carbon Removal in Global South
The nascent but rapidly expanding carbon removal sector recently witnessed a significant financial injection as Alt Carbon, an India-based climate technology innovator, successfully closed a $12 million seed funding round. This substantial capital raise, which stands as the largest seed investment for climate tech in India to date, is earmarked for dramatically scaling its proprietary Enhanced Rock Weathering (ERW) solution across the Global South. For investors eyeing the evolving energy landscape and the critical role of decarbonization, this development signals a growing confidence in scalable, nature-based carbon capture technologies.
Pioneering Enhanced Rock Weathering for Durable Carbon Storage
Founded in 2023 by brothers Shrey and Sparsh Agarwal, Alt Carbon has quickly positioned itself with an ambitious target: removing 5 million metric tons of CO2 from the atmosphere by 2030. Their primary focus remains on Carbon Dioxide Removal (CDR) initiatives within South Asia, leveraging the natural power of Enhanced Rock Weathering. This innovative method involves sourcing basalt rock dust, a byproduct of mining operations, and strategically distributing it across agricultural fields. Here, the basalt naturally reacts with rainwater through a chemical process, transforming atmospheric CO2 into stable bicarbonate ions. These ions are then sequestered within the soil, eventually migrating through river systems to the ocean, where they become integrated as calcium carbonate, a form of storage lasting over 10,000 years.
Beyond its core function of CO2 removal, Alt Carbon’s ERW process offers compelling co-benefits that enhance its investment appeal. The company reports that this method concurrently improves soil health and boosts crop yields, creating a synergistic value proposition for agricultural communities. This dual impact—environmental restoration combined with economic uplift—underscores the potential for widespread adoption and sustainable scaling.
Strategic Projects and Industrial Partnerships Driving Growth
Alt Carbon’s flagship initiative, “The Darjeeling Revival Project” (DRP), exemplifies its integrated approach. This project aims not only to remove significant quantities of CO2 but also to rejuvenate degraded soils and ecosystems, restore local livelihoods, and protect one of India’s most cherished exports: Darjeeling tea. Such initiatives highlight the company’s commitment to community engagement and holistic environmental improvement alongside its technological advancements.
Crucially for investors, Alt Carbon has already forged significant industrial alliances that validate its market potential and operational capabilities. In recent months, the company announced a strategic partnership with Mitsubishi Corporation, a global diversified enterprise, underscoring robust corporate interest in its solutions. Further cementing its commercial viability, Alt Carbon also secured a 10,000-tonne carbon removal offtake agreement with MOL Group, a leading Japanese shipping and logistics conglomerate. These partnerships provide early revenue streams and demonstrate concrete demand for Alt Carbon’s carbon removal credits, a vital component of the burgeoning carbon markets.
Capital Deployment for Accelerated Innovation and Expansion
The fresh $12 million capital infusion is strategically allocated to bolster Alt Carbon’s foundational pillars. A significant portion will fuel Earth Sciences Research & Development, ensuring continuous innovation and optimization of the ERW process. Furthermore, the funding will advance hardware innovations, streamlining the deployment and efficiency of their technology in the field. Critically, these funds will also enable a substantial scale-up of operations, facilitating durable climate action in India and accelerating broader CDR deployment across the Global South. For investors, this signals a clear path from pilot projects to large-scale commercialization, targeting a region ripe for sustainable development and environmental investment.
Sparsh Agarwal, Co-founder and President of Alt Carbon, articulated the company’s overarching vision: “Our ambition is to establish India as a global epicenter for carbon removal. We are committed to removing CO2 at scale from the Global South for the benefit of the entire planet.” He expressed gratitude to the partners supporting their journey to revive Darjeeling, remove CO2, and contribute to global climate mitigation efforts.
Esteemed Investor Backing and Gigaton-Scale Vision
Leading the seed round was Lachy Groom, a renowned tech investor and the Co-founder and CEO of AI startup Physical Intelligence, with participation from existing investors. Groom’s endorsement offers a powerful testament to Alt Carbon’s potential.
“Alt Carbon is tackling a generational challenge,” Groom commented. He praised the founders’ personal dedication, their robust technical methodology, and their ambitious vision, emphasizing that these elements are poised to facilitate CO2 removal from the atmosphere at a gigaton scale. Groom highlighted the dual benefit of adapting agricultural land for climate impact. He further noted the rapid progress made in just 18 months, during which the team established a world-class laboratory, developed proprietary models, and laid the groundwork for an entirely new class of carbon removal and agricultural infrastructure. Describing Alt Carbon as a “category-defining deep-tech company,” Groom believes it will fundamentally reshape global perspectives on climate action and investment in environmental solutions.
Implications for the Oil & Gas Investment Landscape
For investors traditionally focused on oil and gas, Alt Carbon’s success underscores a critical shift in the energy paradigm. As global economies push towards decarbonization, investments in carbon removal technologies like ERW are becoming increasingly central to achieving net-zero targets. This not only creates new market opportunities for climate tech specialists but also presents avenues for traditional energy companies to diversify their portfolios, invest in offset solutions, and transition towards a more sustainable future. The strategic partnerships with industrial giants like Mitsubishi and MOL Group further highlight how established players are integrating carbon removal into their long-term operational and environmental strategies. Alt Carbon’s ability to attract significant capital and forge meaningful alliances positions it as a key player in the evolving carbon economy, offering a compelling case for investors seeking exposure to high-impact, scalable climate solutions that complement and reshape the broader energy investment landscape.
