The New York-based startup is developing standardised, modular nuclear reactors built for the seafloor.

What's the endgame? Momentum Power's reactors are factory-made and shipyard-assembled, using the ocean as a natural heat sink. That design is meant to eliminate cooling towers and on-site concrete, cutting the heavy civil construction that drives the cost and schedule of conventional land-based reactors.

What's the money for? The investment will fund development and commercialisation of the technology, advance engineering and regulatory work, and expand the company as it moves toward deployment.

Who's involved? Momentum Power was co-founded by nuclear scientist Ju Li, its chief scientist and a professor at MIT. Co-chief executive officer Jose Gutierrez previously led Westinghouse ElectricDealroom has a profile for this one.

Why Paulson? He built Paulson & Co. into one of the world's largest hedge funds and now runs Paulson CapitalDealroom has a profile for this one. Try Dealroom →, a private investment firm. "John Paulson is one of the great investment minds of our time, and his decision to invest and join our Board of Directors is a powerful validation of everything we are building," Gutierrez said.

Why now? Paulson framed the appeal in cost terms. "By developing factory-made nuclear modules utilizing existing technology and locating the modules on the ocean floor, Momentum Power has the potential to dramatically reduce the cost of nuclear power and accelerate its adoption," he said.

The signal: The round positions Momentum Power to serve rising demand for reliable, scalable power from data centres, utilities, and energy-intensive industries. Backing from a prominent financier lends early credibility to an unproven approach still far from deployment.
