Ammonia-powered ships have an self-powered leakage monitoring system ...

liquid ammoniais is a promisingmarine fuel in the shipping industry because to its zero carbon, safe storage, and high energy density.

Ammonia is a common toxic gas that can cause irritation to the mucous membranes and the respiratory system. It''s therefore necessary to develop a real-time and accurate ammonia monitoring technique for long-distance sea trips.

Recently, a research group led by Prof. FENG Liang from the Chinese Academy of Sciences (CAS) developed a full-set self-powered ammonia leakage monitor system for ammonia-energy ships.

A honeycomb triboelectric nanogenerator (TENG)-based power generation system, a carbon nanotube doped ammonia detection system, and a signal collecting and transmitting system (bluetooth).

This paper was published inNano Energyon April 11.

Through the synergistic effects between carbon nanotubes and conductive polymers, the researchers improved the electronic conduction efficiency. Several factors contributed to the sensor''s high detection range (about 90 seconds), high selectivity, high stability and a lower cost.

Over the course of the bluetooth, the researchers realized that wireless transmission from the detection module to the computer terminal was accomplished.

By combining with the honeycomb structure TENG provided by Dalian Maritime University, the system might collect and cover the mechanical energy generated by the ship''s engine into electrical energy, achieving self-driving of the entire sensing system.

The researchers performed experiments on the expedition ship, which included a robust tracking system that could be used in practical applications.

"The self-powered wireless detection system is capable of providing long-term maintenance-free monitoring of ammonia leakage during ocean trips," said Prof. FENG. "Itis expected to play an important role in the future use and promotion of ammonia energy."
