The Ocean’s Energy Can Be Harnessed To Power Ocean Sensors

-

Pacific Northwest National Laboratory is working on a way to provide long-term power for the myriad of sensors in our oceans.

Most sensors have a limited life due to their battery capacity. Replacing batteries at sea is expensive and can even be dangerous. That is why PNNL is looking for a way to power ocean sensors indefinitely using the ocean’s energy.

The team is working on a new cylindrical triboelectric nanogenerator (TENG). These have the capacity to convert large amounts of wave energy into electricity to power the ocean sensors. According to PNNL laboratory fellow and co-developer of the new TENG device Daniel Deng:

“TENGs are low cost, lightweight, and can efficiently convert slow, uniform or random waves into power—making them particularly well-suited to powering devices in the open ocean where monitoring and access are challenging and costly. We’re developing the FMC-TENG to power everything from ocean observing platforms with multiple sensors to satellite communications, all using the power of the ocean.”

He added:

“The FMC-TENG is unique because there are very few wave energy converters that are efficient and able to generate significant power from low-frequency ocean waves. This type of generator could potentially power integrated buoys with sensor arrays to track open ocean water, wind, and climate data entirely using renewable ocean energy.”
