Climate Tech Startup Aims to Capture Carbon and Improve Data Center Cooling

280 Earth, a startup from Google’s X, is developing tech to capture CO2 from air, reuse server waste heat, and generate water.

Data centers are a growing climate problem, especially as the energy needed to train AI models inflates tech companies’ carbon footprints. A startup that emerged from Google’s X lab claims its technology can provide a solution by pulling carbon dioxide out of the air, utilizing servers’ waste heat, and generating water to help cool data centers more efficiently.

280 Earth’s Innovative Approach

The company, 280 Earth, has signed a $40 million agreement to capture carbon dioxide emissions for major players through the Frontier initiative. This initiative, launched by Stripe, Alphabet, Meta, Shopify, and McKinsey in 2022, supports emerging carbon removal technology. Buyers include these founding members, along with Autodesk, H&M Group, JPMorgan Chase, and Workday.

Frontier Initiative and Carbon Removal

Filtering CO2 out of the air is trending among companies aiming to meet sustainability targets. Frontier has brokered deals with other startups using rocks, liquid smoke, and sewage to capture carbon. “When we started 280 Earth as a moonshot at X, our vision was always to find a radically effective, affordable, and scalable way to remove billions of tons of carbon from our atmosphere. We’re excited to see this momentum with Frontier buyers,” said Astro Teller, captain of moonshots at Alphabet’s X.

How 280 Earth’s Technology Works

280 Earth builds modules with absorbent materials, known as sorbents, to filter CO2 from the air. Similar to direct air capture (DAC) plants, 280 Earth’s technology claims to be more efficient, working in tandem with data centers by drawing power from their waste heat. Unlike other DAC technologies that work in big batches, 280 Earth operates continuously, saving energy by avoiding the need to reheat and cool a single chamber.

Additionally, 280 Earth’s technology captures water vapor, extracting two to four tons of water for every ton of CO2 captured. “It’s like the difference between a home oven and a professional pizza oven,” explains 280 Earth CEO John Pimentel. The technology retains heat better and avoids energy loss, optimizing efficiency.

Benefits and Challenges

280 Earth’s technology not only captures CO2 but also provides water for cooling systems, addressing the high energy and water consumption of data centers. However, the biggest challenge is scaling the technology to reduce costs. Currently, capturing CO2 is prohibitively expensive. The pilot facility in Oregon aims to capture 61,600 tons of CO2 by 2030, costing more than $600 per ton. The company plans to sequester the captured CO2 in underground storage wells in the US.

Google alone was responsible for 14.3 million metric tons of CO2 pollution in 2023, highlighting the need for larger-scale carbon removal solutions. Scaling up carbon removal can bring costs down and provide a transition period while companies shift to cleaner energy. “As much as we all want to believe that transition off of fossil fuels is going to happen quickly… It’s going to take decades,” Pimentel says. “In the meantime, we’re continuing to pump more CO2 into the atmosphere, exacerbating the problems that we already have. So I’m a believer in the all of the above solution.”

Industry Impact and Future Prospects

280 Earth’s innovative approach could create a win-win situation for data centers and other industrial facilities. Data centers, notorious for high electricity and water consumption, could benefit significantly from this technology. The potential to draw waste heat and produce water for cooling systems can help reduce operational costs and environmental impact.

However, environmental groups express concern about relying on new carbon capture technologies. These methods are still unproven at scale and expensive. As the industry evolves, it is crucial to balance immediate carbon removal efforts with long-term sustainability goals.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
