Cella

What a couple of weeks. After launching Project Jacaranda (link in the comments) - one of the first DAC + mineralization pilots in the world - the Cella team took a step back to reconnect, refocus, and recalibrate. For the first time, our U.S. and Kenya-based teams met in person, after months (or years) of working together virtually. If you’ve ever gone from Zoom calls to real-life collaboration, you know the shift. It's surreal. Conversations flow differently, ideas evolve faster, and those small in-between moments (over breakfast, on a hike, or staring at a Rift Valley sunset) deepen trust in ways that no Slack channel ever could. But beyond just bonding, we tackled the hard questions: What does Cella need to do next? What’s working? What’s not? What does success look like in 2025? Surrounded by wildlife (yes, actual lions), we mapped out a clearer vision, challenged our assumptions, and set the groundwork for a year of real progress. The work ahead is big, but so is the momentum. To anyone running remote teams, scaling climate tech, or just navigating the messy middle of startup growth: when was the last time you stepped back to reframe the big picture? #carbonremoval #climatetech #startups #teamwork

?? An exciting milestone for carbon removal and permanent storage ?? We’re proud to announce the launch of Project Jacaranda - a groundbreaking collaboration between Cella and Sirona Technologies in the Rift Valley. As one of the first projects of its kind, it is scaling carbon dioxide removal while harnessing local innovation and expertise to create lasting, permanent impact. Project Jacaranda combines Sirona's innovative DAC technology, which captures CO? directly from the atmosphere, with Cella's expertise and technology for injecting CO? into basalt formations. Through this process, the CO? is naturally transformed into rock, providing safe and permanent carbon storage. A huge thank you to Sirona Technologies and all partners who helped make this possible. This is just the beginning of what we can achieve together.

Last week, we were in #Nairobi for the Africa Tech Summit engaging with market players and tech leaders within the African ecosystem about the opportunity for carbon removals in the region. At the event, ClimeFi’s Co-Founder, Sebastien Dewarrat provided his insights as part of a panel titled ‘Unlocking Kenya’s Green Economy: New Models For Energy Development and Carbon Removal Sirona and Cella’. Other contributors to the discussion included Thoralf Gutierrez, CEO of Sirona Technologies, Claire Nelson, Co-Founder and CTO of Cella, Anthony Kuria, Project Coordinator and Legal Advisor at Mumbi Limited, and Faith Temba, Climate Advisor at Office of Kenya's Special Envoy for Climate. The panel took a deep dive into how carbon removals are integrated into the Kenyan economy, as well as exploring Kenya’s position as an attractive economy for deploying scalable #CDR solutions. Thank you to those who organised the event, as well as those who contributed to the conversations helping to drive the carbon removal agenda forward in Africa. If you met with Sebastien in Kenya, please do not hesitate to get in touch. #ClimeFi #AfricanTechSummit #ClimateAction #CarbonRemoval

This week, we participated in a constructive follow-up meeting with the JICA Community in Gilgil, hosted by Sirona Technologies in collaboration with Mumbi, KenGen Kenya, and Cella. Building on last year’s discussions, we revisited key priorities identified by the local community. This time, the focus was on addressing one of those immediate needs - improving water access by piping it from a nearby reservoir. Progress doesn’t happen overnight, but meaningful conversations like this bring us closer. We look forward to continuing this important work. #CommunityEngagement #Collaboration #Cella #Sustainability

Join us at @AfricaTechSMT in Nairobi, 12th – 13th Feb, to explore the latest trends shaping Africa’s vibrant tech ecosystem. Our co-founder and CTO, Claire Nelson, will be speaking on the panel: “Unlocking Kenya’s Green Economy – New Models for Energy Development and Carbon Removal with Sirona and Cella.” Don’t hesitate to reach out in advance to connect!

It was great to kick off our participation in the Halliburton Labs program in Houston and meet with Halliburton CEO Jeff Miller. We look forward to more productive collaboration as we scale our CO? mineralization technology and advance sustainable CO? storage solutions. ??: Our founding team, Claire Nelson and Corey Pattison with Jeff Miller #ClimateTech #CO2Storage #HalliburtonLabs #Innovation #Sustainability

Meet one of the innovative energy startups in the new Halliburton Labs cohort: Cella advances subsurface mineralization of carbon dioxide. The company’s end-to-end services, from resource assessment to proprietary injection technology, and monitoring techniques, provide valuable geologic carbon storage solutions. Cella aims to build its first field-scale pilot to demonstrate its novel approach to mineralization. Cella’s notable team uses industry-leading scientific and operational experience supported by advisors that pioneered the field of carbon mineralization in basalt. Co-founder and Chief Technology Officer Dr. Claire Nelson said, "Collaboration with Halliburton Labs enables us to leverage world-class experience and resources to scale our technology and bring our services to market. We're excited to demonstrate how our innovations can be easily integrated with existing, state-of-the-art subsurface technologies to enable rapid advancements in the field of geologic carbon storage."

The #XPRIZECarbonRemoval team recently visited finalists Octavia Carbon and Cella in Kenya’s Great Rift Valley, where innovation and collaboration are paving the way for impactful carbon removal solutions! ???? Octavia and Cella have partnered to combine Direct Air Capture (DAC) technology with permanent CO2 storage through mineralization. During the visit, the XPRIZE team had the opportunity to tour Octavia’s DAC facility, where modular machines, designed and built locally by engineers and technicians from Nairobi’s universities and technical colleges, remove CO2 directly from the air. These machines are powered by the Rift Valley’s abundant geothermal energy, making the process both innovative and sustainable. Just down the road, the team explored Cella’s mineralization well, where the CO2 is permanently stored deep underground in volcanic rock. This site marks an exciting step forward as the first CO2 mineralization well in the region, ensuring that carbon removal is both effective and enduring. Seeing the synergy between Octavia’s air capture technology and Cella’s permanent storage approach firsthand highlighted the potential of local expertise and resources in driving meaningful climate action. Kenya’s Great Rift Valley offered the perfect backdrop for this work, showcasing how local innovation and sustainable energy can be harnessed to address global climate challenges.
