Suzhou Sizhuimu raises $1.5 million to build damless underwater microgrids

What's the deal? Suzhou Sizhuimu TechnologyDealroom has a profile for this one. Try Dealroom → has raised 10,000,000 CNY (about $1.5 million) in an angel round, the company said in September 2026. It develops distributed, damless underwater microgrids built around its own water-turbine generators.

What's the endgame? Sizhuimu targets tidal and river energy, using in-situ underwater charging and array-based generation to form grids. It aims to supply stable, clean power to water-based equipment, marine facilities, and coastal energy sites.

Why now? The company sticks to a modular, array-style technical approach — a design meant to scale by adding units rather than building large fixed structures. The angel funding gives it early capital to advance that hardware.

The signal: The round sits toward the smaller end of deals in its cohort, placing it in roughly the 36th percentile by amount. That fits an early-stage bet on clean-energy hardware, where modest first cheques test unproven technology before larger raises.
