Deep dives
Mantle's Point-Source Carbon Capture Solution
Mantle is developing a point-source carbon capture solution that can sit next to industrial equipment and capture emissions. They use a high-temperature liquid phase material for carbon capture, operating at 600 degrees Celsius without deterioration or decay. The controversy around point-source carbon capture is discussed, with some arguing it extends the life of high emissions processes while others see it as necessary to reduce emissions in hard-to-abate sectors. Mantle's unique go-to-market approach minimizes integration dependency for industrial customers, making it easier to pilot their technology. The company raised a seed round led by The Engine, an MIT fund focused on tough tech startups.
The Goal of Net Zero Emissions by 2050
The goal of achieving net zero emissions by 2050 is emphasized. Carbon capture plays a critical role in achieving this goal by capturing 95%+ of emissions in various industries, supplemented with carbon removal. Advocates argue that if emissions can be captured and supplemented with removal, there's no need to entirely replace emitters as long as they are cleaned up. The challenge is achieving cost-effective carbon capture, which Mantle aims to address.
Mantle's Technology and Integration Approach
Mantle's capture technology involves scrubbers that remove CO2 from emissions. The systems resemble existing scrubbers and can be integrated into industrial assets in a way that minimizes impact on the existing processes. Initially, Mantle focuses on gas-fired boilers that capture their own emissions and addresses the challenge of integrating into existing assets. Future plans involve scaling up to decarbonize assets such as steel and cement plants. The goal is to provide a low-cost path to decarbonize hard-to-abate sectors.
Expansion to Biogenic Carbon Capture
Mantle sees potential in applying their carbon capture technology to biogenic sources of carbon emissions, such as pulp and paper production and biomass burning. By capturing CO2 from biomass combustion, negative emissions can be achieved. This approach demonstrates the potential for large-scale carbon removal in sectors that are difficult to fully decarbonize.
Challenges and Future Steps
Mantle faces challenges in ensuring engineering reliability, safety, and cost-effectiveness as they move from lab-scale to industrial-scale deployment. Their upcoming double-decker bus-sized demonstration system will validate the engineering aspects. Subsequent steps involve proving cost-effectiveness and deploying their technology at scale. The urgent need to rapidly deploy carbon capture solutions to tackle the global emissions problem is emphasized.
Mantel is developing a point source carbon capture solution, which means they're developing technology that can sit next to industrial equipment and capture its emissions. Mantel's key innovation lies in their utilization of a high-temperature liquid-phase material for carbon capture, enabling operation at temperatures as high as 600 degrees Celsius. Allegedly, this material can cycle between capture and release without experiencing deterioration or decay.
Point source carbon capture is somewhat controversial, as detractors argue that it extends the life of high-emissions processes. Promoters argue that we need all solutions on the table to reduce emissions in hard-to-abate sectors. Cameron and Cody discuss this at the start of the episode, before diving into his technology and go-to-market solution. He articulates a unique approach to go-to-market, wherein he's determined a way to minimize the integration dependency that his industrial customers would have to take on in order to get a pilot up and running with Mantel. Cameron maintains a close affiliation with MIT, having earned both his PhD and MBA there. In 2022, Mantel secured a seed round of funding, led by The Engine—a venture fund founded by MIT with a focus on tough tech.
