Mantel Raises $2M in Funding

MantelThe Boston, MA-based developer of an innovative solution to carbon collection, received $2m in funding.

The round was led by The Engine, the venture firm spun out of MIT that invests in early-stage Tough Tech companies, with participation from New Climate Ventures.

This funding will accelerate the company’s technology development, prototype testing and initial deployment.

Mantel was founded in 2022 by Cameron Halliday as CEO, Danielle Colson as COO, and Sean Robertson as CTO. It is a high-temperature liquid-phase carbon capture system that can withstand the high temperatures found in furnaces, kilns and boilers. The company is creating a platform to reduce emissions in difficult-to-abate industries like industrial heat, cement and steel. It can also be used in hard-to-abate areas where natural gas and energy derived from coal are likely to continue for decades. Additionally, the technology can be utilized for carbon dioxide removal from the atmosphere through pairing with biogenic sources of emissions, such as bioenergy, waste-to-energy and pulp & paper.

Mantel was created at MIT after research was completed with Takuya and Takuya Hatton. The company plans to use new capital to build a demonstration plant at a commercial scale after a lab-scale flow loop demonstration has been completed.
