Chinese scientists have developed a new energy cell that converts environmental heat into electrical energy and is not dependent on sunlight. The system, called HHC (Hermetic Hydrovoltaic Cell), requires only a very small amount of water for energy production and can operate efficiently even in harsh environmental conditions such as deserts.

China announces HHC system, a next-generation energy cell that works in the dark

The HHC system overcomes a fundamental limitation of conventional solar panels and is able to produce energy around the clock. The technology can even work at night or in dark environments. The system includes an internal structure of carbon black and absorbent paper and a layer that allows water to circulate continuously. It takes advantage of temperature differences to evaporate water and generate electricity.

In tests, the cell was able to generate power for 160 hours without interruption and water consumption was negligible. Based on the results, we can say that HHC could be an ideal energy solution for regions such as deserts where water resources are limited.

Photothermal support and the effect of light

Incidentally, this technology becomes more efficient under light. The carbon black material absorbs light, increasing the internal humidity level and boosting electricity production. So, we are talking about a versatile system that can work both in the dark and in the light. The HHC technology has been congratulated for its low-cost production, easy installation and environmental sustainability.

The researchers hope that this system will inspire future energy solutions, according to a paper published in the journal Nature Communications. How do you think this innovation will contribute to the spread of renewable energy sources? Please leave your comments in the comments section below.
