US sustainability projects on the platform don’t cluster around one sector — clean water tech, sustainable transport, renewable energy, and services all show up in roughly equal measure. Looking at real organizations, three approaches keep showing up.

1 Make clean water and energy accessible off-grid

A recurring US pattern: technology that produces clean water or power without needing existing grid or utility infrastructure, useful in both remote and urban settings.

Water Tech

Zero Mass Water

Hydropanel technology that creates clean drinking water directly from sunlight and air.

Water Treatment

Microvi

Biosolutions tackling contaminants in drinking water and wastewater using natural methods.

Community Solar

Solstice

Access to solar energy savings without rooftop panels, via local solar gardens.

2 Diversify renewable energy generation

A second group goes beyond solar and wind to less conventional renewable sources — ocean currents, vertical turbines — expanding where clean energy can realistically be generated.

Florida

Hydrokinetic Energy Corp.

Hydrokinetic turbines harnessing ocean currents to produce clean electricity, green hydrogen, and freshwater.

Wind

WindStax Energy

Integrated renewable energy combining vertical wind turbines and solar microgrids.

Monitoring

Aquaai

Fishlike sensor platform collecting subsurface data to support sustainable water management.

3 Rethink everyday transport

The third pattern brings sustainability to daily transport choices — electric bikes, and platforms connecting people with cleantech job opportunities to grow the sector’s workforce.

E-Mobility

Calibike

Lightweight electric bikes designed for comfort, efficiency, and greener urban mobility.

Workforce

Cleantech Rising

Non-profit connecting people with clean technology jobs and educational resources.

Supply Chain

Sustainment Technologies

Strategic sourcing and supplier management platform supporting sustainable procurement.
