Summer Engineering Internship

  • Engineering
  • Full-time
  • Cambridge, MA

Posted on January 7, 2025

Mantel is a startup backed by Shel, Eni Next, BP, Breakthrough Energy, The Engine and New Climate Ventures. Mantel, born out of MIT, was founded by two MIT scientists and a Harvard MBA.

Mantel is developing the material solution to carbon capture. Our molten borates are designed to operate at the high temperatures found inside boilers, kilns, and furnaces – enabling highly efficient carbon capture that has not been possible until now. Carbon capture can be applied across industry to reduce emissions - and even achieve net-negative emissions. By solving for efficiency Mantel can reduce energy losses by more than 60% and cut costs in half, unlocking carbon capture’s role in reaching net-zero emissions globally.

Mantel is looking for a Summer Engineering Intern excited to join a promising carbon capture startup working on the development of molten salts as a novel CO2 sorbent material. Mantel is looking for both undergrad and graduate level interns from a variety of backgrounds including Chemical Engineering, Mechanical Engineering and Materials Science who are interested in gaining machine shop, prototyping and fabrication experience.

Summer Interns will be given the opportunity to work on a variety of science and engineering problems:

  • Improving our understanding of the performance of different material of construction candidates.

  • Running, analyzing and modifying lab-based carbon capture experiments

  • Design and fabrication of new diagnostics or components for our lab-based pilot with access to a fully kitted machine shop, state of the art 3D printing facilities and electronics lab.
