Mantel Capture, a technology provider of a carbon capture system using molten borates, announced it has raised $30 million in Series A funding co-led by Shell Ventures and Eni Next. And additional participating investors include Engine Ventures, New Climate Ventures, Hartree, bp Ventures, Arosa Ventures, Vale Ventures, Newlab, MCJ Collective, and others.
This funding round will be used to implement a demonstration project at an industrial site and help pave the way for full-scale commercial deployment of Mantel’s high-temperature carbon capture systems. And the company’s technology has already demonstrated carbon capture at lab scale of half a tonne per day, and the upcoming project will be around 10 times larger, rated to capture 1,800 tons of carbon dioxide emissions per year at an industrial site.
Carbon capture involves collecting carbon dioxide produced from large sources such as power plants and other industrial facilities. And the captured carbon dioxide is then compressed, transported and used for a variety of applications or stored underground, preventing its release into the atmosphere.
Mantel utilizes molten borates, the only high-temperature liquid-phase carbon capture material, to capture carbon dioxide at the emission source. By operating at high temperatures, Mantel’s systems recover high-grade heat by capturing carbon dioxide (absorption), offsetting the energy necessary to regenerate the molten borate material (desorption). And this enables Mantel to capture carbon dioxide from industrial emissions efficiently, reducing capture costs by over half compared to conventional amine-based carbon capture technologies, which helps render installing Mantel’s carbon capture technology at heavy industry sites economically feasible. As more carbon capture equipment is installed, it is expected this will prompt more investment in infrastructure, further driving down costs of carbon capture, transport and storage.
Cameron Halliday, Danielle Rapson, and Sean Robertson launched Mantel in 2022 as a spin-out from the Hatton Research Group in MIT’s Department of Chemical Engineering. That same year, the company raised a $2 million seed round and joined the Breakthrough Energy Fellows program.
KEY QUOTES:
“With support from both investors and industry leaders, we are eager to showcase the effectiveness of Mantel’s technology across industrial applications and demonstrate its potential to be the lowest cost pathway to net zero emissions for our industrial customers. This investment enables us to transition from lab-pilot success to working with customers to design and prepare for the deployment of full-scale commercial projects.”
- Cameron Halliday, co-founder and CEO of Mantel
“Shell Ventures is pleased to support Mantel and the development of its innovative carbon capture technology. We believe carbon capture and storage offers a way to reduce emissions, especially for hard-to-abate sectors. However, for widespread adoption of carbon capture to be feasible, it must be cost effective. Mantel’s innovative solution has the potential to significantly lower carbon capture costs and can be applied across diverse sectors, including natural gas power plants and hard-to-abate industries like cement, steel and chemicals.”
- Hector MacQuarrie, Principal at Shell Ventures
“For Eni Next, carbon capture and storage is a key lever for the energy transition. Mantel’s technology offers the potential to significantly decrease the cost of capture thanks to its innovative solvent. Making carbon capture affordable is key to its deployment across hard-to-abate industries. Eni Next is looking forward to teaming up with Mantel to make it a success.”
- Clara Andreoletti, CEO of Eni Next
“Point source carbon capture is a critical piece to cost-effectively decarbonize heavy industry. With new capital and commercial opportunities emerging across the world, Mantel is positioned to rapidly scale its low-cost carbon capture technology.”
