Field Evaluation: Stable H₂ Leak Detection in Taiwan’s Hot and Humid Climate

What happens when hydrogen leak detection leaves the laboratory?

That question sits at the heart of an ongoing (it started over 6 months ago) green hydrogen demonstration project in Taiwan. ,The project has been evaluating hydrogen production, storage and fuel cell technologies as part of an integrated energy system. Flusso’s hydrogen leak detection technology has been installed to assess its performance in a practical operating environment.

Understanding the Demonstration Project

The Taiwan demonstration combines hydrogen production, storage and fuel cell technologies within a single integrated energy system. Use the tabs below to explore each stage of the project.

Renewable electricity provides the foundation for the demonstration system. Rather than being used immediately, electrical energy can be converted into hydrogen, creating a means of storing renewable energy for use when demand arises.

At the heart of the demonstration system is a HIPOWER 8kW LT-PEM electrolyser. Using renewable electricity, the electrolyser generates hydrogen that can be stored and later used to produce electricity when required.

Hydrogen leak detection is integrated within the control and instrumentation enclosure, close to key hydrogen gas-handling components. Flusso’s hydrogen leak detection technology was installed as part of the demonstration project to evaluate its performance within a real-world operating environment.

The demonstration system uses a Panasonic fuel cell to convert stored hydrogen into electrical power. By generating electricity on demand, the fuel cell helps illustrate the role hydrogen can play in supporting a more flexible and resilient energy infrastructure.

The final stage of the system demonstrates how stored hydrogen can be converted into practical value. Electricity generated by the fuel cell can be used to support energy storage, peak shaving and backup power applications.

Field Evaluation Results

Following installation within the demonstration system, Flusso’s hydrogen leak detection technology was evaluated under a range of operating conditions representative of real-world hydrogen infrastructure.

During the evaluation period, ambient temperatures ranged from 18°C to 38°C, with enclosure temperatures remaining below 50°C and humidity levels reaching 100% RH. No observed drift, false alarms or sensor poisoning were reported, and the sensor maintained a stable baseline throughout testing.

Hydrogen purge events occurring approximately two metres from the sensor location were successfully detected. The evaluation took place in a semi-open installation, creating a practical outdoor environment rather than a controlled laboratory test.

We did hydrogen purging several times, about two metres away from the sensor. The sensor could still see these small events clearly, and every time the purge stopped, the signal came back to baseline. Even with the high humidity and temperature, we did not see the baseline moving. For us, that was a very good result.

Looking Ahead

Real-world validation is an important step in the adoption of hydrogen technologies. The ongoing demonstration project continues to provide valuable insight into how hydrogen systems perform under practical operating conditions, helping build confidence in the technologies that support safe and reliable operation.
