The Boulder startup is teaching batteries, refrigerators and microgrids to anticipate the expensive hour. Its pitch is simple: make demand flexible before building more supply.
Aeromine Technologies builds a motionless, bladeless rooftop wind energy system for commercial and industrial buildings. Its 10-foot units sit along a roof's edge and use vertical airfoils to capture and amplify a building's own airflow, generating electricity silently and without spinning blades. The company says the system can produce up to 50% more energy than a comparable rooftop solar array while using roughly 10% of the roof space, and it is designed to complement, not replace, solar. Founded in 2021 and headquartered in Houston, Aeromine has run pilots with BASF and BMW Group and raised a ~$9M Series A led by Veriten in 2024.
Last Energy is a US-based developer of factory-built micro modular nuclear power plants. Its flagship PWR-20 is a 20-megawatt pressurized water reactor assembled from truck-shippable modules and delivered as a turnkey, build-own-operate service. Rather than selling reactors, Last Energy sells electricity and heat under long-term power purchase agreements, targeting data centers and energy-intensive industries that need reliable, carbon-free baseload power without financing or operating a plant themselves.
