Energy & Sustainability Client Feature – Mantel Capture

This month, we are excited to feature Mantel Capture, a company developing carbon capture materials and systems to remove CO2 from flue emissions in heavy industrial sectors. Mantel's novel application of molten alkali metal borates enables efficient recovery of heat energy, which in turn allows for a more efficient carbon capture method. Mantel's solution is the first high-temperature, liquid-phase carbon capture system that can recover useful energy as high-quality steam or heat.

Mantel recently closed a $30 million Series A round with funding co-led by Shell Ventures and Eni Next with additional participation from Engine Ventures, New Climate Ventures, and others. The new raise will allow Mantel to move forward with a demonstration project at a paper mill with the potential for capturing 1,800 metric tons of emissions per year. By pairing with biogenic sources of emissions, such as pulp & paper, bioenergy, and waste-to-energy, Mantel can compound the benefits
