# VEIR

> VEIR is a Woburn, Massachusetts company commercializing high-temperature superconducting power lines that move 5 to 10 times more electricity than conventional cables at the same voltage and footprint. Its key breakthrough is a passive, evaporative liquid-nitrogen cooling system that keeps superconductors cold without heavy machinery. Founded in 2019 out of Breakthrough Energy Ventures research, VEIR targets utilities, renewable developers, and increasingly the power-hungry AI data center market. It closed a $75M Series B in January 2025 led by Munich Re Ventures, with backing from Microsoft's Climate Innovation Fund.

- **Founded:** 2019
- **Headquarters:** Woburn, Massachusetts, United States
- **Founders:** Tim Heidel (Co-Founder & CEO), Steve Ashworth (Co-Founder (cooling system concept))
- **Team size:** ~110 employees
- **Products:** Superconducting overhead transmission lines, Passive evaporative nitrogen cooling system, Superconducting power solutions for AI data centers
- **Notable:** Built and operated a 100-foot superconducting transmission demonstration line in Woburn, Massachusetts., Closed a $75M Series B in January 2025 led by Munich Re Ventures with Microsoft Climate Innovation Fund participating., Raised roughly $117M in total funding.

## Products & services

- **Superconducting overhead transmission lines** — High-temperature superconducting (HTS) tape cables that carry 5-10x the power of conventional steel-and-aluminum lines at the same voltage and footprint; initial AC capability up to ~400 MW at 69 kV with multi-gigawatt and DC versions planned.
- **Passive evaporative nitrogen cooling system** — A proprietary cooling architecture that runs liquid nitrogen (-321F) through a vacuum-insulated pipe surrounding the superconductor, delivering roughly 20x the cooling power per kilogram of coolant flow versus conventional approaches - largely passive, with no heavy mechanical chillers.
- **Superconducting power solutions for AI data centers** — Megawatt-class, low-voltage superconducting cables for inside data centers that move power 5x farther using 20x less space than copper - aimed at the jump to multi-megawatt racks.
