Maritime Fusion Raises $4.5M in Seed Funding

Since then we’ve stood up our HTS magnet lab in San Francisco and have been rapidly iterating and testing prototype cables and magnets. Below is a snapshot from a recent bench test where we ran 5kA through our HTS cable SHIELD —Superconducting High Integrity Energy Link & Distribution— with liquid Nitrogen as the coolant.

In parallel, we’re advancing the physics basis for Yinsen, a low–power-density HTS tokamak and are excited to be partnering with both Columbia University via a Sponsored Research Agreement, and the Department of Energy’s DIII-D National Fusion Facility as a user to run experiments focused on our pulse scenario.

We’re Hiring Across the Company

We’re hiring to grow both our HTS cable program and tokamak design efforts:

• Member of Technical Staff: Electrical, Mechanical, Systems, Thermal, Manufacturing, Plasma Physics, Nuclear
• R&D Technicians
• Business Development & Strategic Partnerships

If you’ve worked with high current, cryogenics/vacuum systems, moving MW’s, REBCO, or magnetic confinement, we want to hear from you. Apply at Maritime Fusion Jobs

SHIELD Cable Architecture

Our patent pending SHIELD design has a cross section smaller than a quarter (not including cryostat) but designed to handle up to 8kA at 77K self-field, and even higher current at fusion relevant conditions (20K, 20T).

One key feature is the modularity of the design that allows for easily packaging N x N insulated cable bundles. This architecture allows for industry leading steady state engineering current densities while maintaining thermal stability and mechanical robustness.
