Atmospheric Humidity to Electricity Conversion Technology for Sustainable Power Generation

energyTestedTRL 5

Imagine a solar panel, but instead of needing sunlight, it pulls electricity directly from the moisture in the air. It works like a sponge for humidity, turning that water vapor into a steady stream of power. This means you could generate electricity even in the dark or in damp environments.

The business problem

What needed solving

Current renewable energy relies heavily on sunlight or wind, leaving gaps in power generation during the night or in specific climates. There is a need for a continuous, sustainable energy source that can operate independently of weather conditions.

The solution

What was built

A first-generation humidity-to-electricity converter prototype and a validated lab-scale design targeting 15-20 W/m2.

Who can put this to work

IoT & Electronics
SME
Target: Low-power sensor manufacturer

If you are a sensor manufacturer dealing with battery replacement costs in humid environments — this project developed a converter that targets an output power density of 15-20 mW/cm2. This allows devices to harvest energy from the air, reducing reliance on disposable batteries.

Renewable Energy
enterprise
Target: Green energy infrastructure provider

If you are an energy provider dealing with the intermittency of solar and wind — this project developed a humidity-to-electricity technology that provides a new sustainable source of power. It aims for a validated lab-scale output of 15-20 W/m2 to integrate with existing electrical systems.

Smart Buildings
mid-size
Target: HVAC and building automation firm

If you are a building automation firm dealing with high energy consumption for climate control — this project developed a device that captures electricity from atmospheric humidity. This could turn damp indoor air into a source of supplemental power for building electronics.
