Mantel raises $30 million for borate carbon capture

Mantel Capture, a start-up founded by researchers from Alan Hatton’s lab at the Massachusetts Institute of Technology, has raised $30 million in series A funding to develop a carbon capture technology based on a novel sorbent: molten borates. The company says the system can reduce costs by more than half compared to the most mature carbon capture technology, which is based on amine solvents . Mantel will use the funding, which was co-led by Shell Ventures and Eni Next, to demonstrate the technology at a pulp and paper mill. In industrial carbon capture, carbon dioxide is captured from an emission source in a sorbent; it’s later removed in an energy- intensive and expensive regeneration step. Reducing the cost of carbon capture is necessary to help the planet reach net- zero emissions by 2050, Mantel says. Mantel’s technology takes advantage of the fact that carbon capture produces energy when CO 2
