Sustainable Gas Sensor Technology｜RIKEN KEIKI Co., Ltd.

To reduce greenhouse gas emissions such as carbon dioxide and methane, the development of next-generation energy sources that ensure a stable and sustainable energy supply is an urgent priority. In addition to renewable energy sources like solar, wind, and hydropower, gases such as hydrogen and ammonia are gaining attention as promising new energy options.

Ensuring the safe management of a stable energy supply as part of infrastructure, along with effective gas monitoring for facility control, is crucial.

Optimizing Methanation Efficiency

Real-time gas concentration monitoring within the plant needs to be implemented to allow immediate system adjustments in line with the methane generation situation. While gas chromatography (GC) has traditionally been the standard method for analyzing mixed gas samples, its limitations—including slow measurement response, lack of continuous monitoring, and the need for on-site analysis rooms due to the lack of explosion-proof capabilities—pose challenges for widespread implementation.

Riken Keiki has developed a high-precision calorimeter designed for methanation facility control. It offers real-time monitoring, explosion-proof capabilities, and accuracy comparable to GC.

Efficient, Precise Detection in
Real Time

Our Real-Time Gas Monitoring System (RTGMS) utilizes our gas sensor technology, combining multiple sensors to measure the concentrations of various components in mixed gases in real time.

Its explosion-proof design allows direct installation within plants. By integrating RTGMS into methanation plants, facility control can be significantly improved, leading to more efficient and precise system operation.

We manufacture the most advanced gas detection products available to meet the industry's growing needs.

Ammonia as a Key to Next-Generation Energy Solutions

Ammonia is widely produced and consumed in industries such as fertilizers and as base materials for chemical products. The technologies for its production, transportation, and storage are already well-established, with safety measures and guidelines in place.

As a result, ammonia's application in the energy sector is gaining attention, particularly for use as fuel in marine applications. One major advantage is that ammonia transport vessels already exist, equipped with dedicated storage and safety systems to maintain and preserve ammonia as cargo. This eliminates the need to specifically secure refueling infrastructure, such as bunkering vessels.

Moreover, before ammonia-fueled ships became viable, LNG-fueled vessels were developed using technology adapted from LNG transport ships. This existing expertise can now be leveraged to accelerate the development of ammonia-fueled ships.

Diverse Solutions for Diverse
Requirements

We provide advanced gas monitoring solutions for ammonia-fueled ships. Ammonia-fueled ships require different gas concentration thresholds, alarm systems, and shutdown mechanisms for managing atmospheric emissions and fuel control, in addition to the standard concentration values used for workspace management.

In other words, these ships may need measurement methods that differ from traditional ammonia gas monitoring. With the introduction of multiple ammonia measurement requirements, a wider range of gas concentrations will need to be measured, requiring the use of various gas monitors with different detection principles. That is to say, compared to the traditional ammonia gas leak measurements for toxic gases on ammonia carriers, the number of ammonia leakage monitoring points will significantly increase, leading to greater complexity.

With our proven expertise in gas monitoring for ammonia-fueled vessels, we are ready to provide you with the most reliable solutions. Don’t hesitate to reach out to us for more information.

Achieving Stable Operation with Hydrogen Co-Firing

When burned, hydrogen reacts with oxygen to produce water while generating energy—without emitting carbon dioxide. This makes hydrogen a highly attractive next-generation energy source for achieving carbon neutrality.

However, technical challenges such as hydrogen embrittlement and combustion chamber design make it difficult to use pure hydrogen for power generation. As a result, co-firing, which blends hydrogen with existing fuels, has become the preferred approach.

Real-Time Measurement for
Stable Combustion

In hydrogen co-firing power generation, turbines cannot operate solely on hydrogen due to its low energy density. High-calorific natural gas is used during the startup phase, and as the system stabilizes, the ratio of hydrogen in the mix is gradually increased.

However, variations in calorific value during co-firing can lead to combustion vibration, causing damage to turbine blades and shafts. To prevent this, real-time monitoring and feedback on the calorific values of the fuel supplied to the turbine are essential. <br><br>With RTGMS, ignition timing and air-fuel ratio can be precisely controlled in real time, ensuring stable combustion and optimizing turbine performance.
