Hydrogen & Methane Gas Sensors Frequently Asked Questions

FAQ

Gas sensors play a critical role in detecting and monitoring various gases across industries like energy, manufacturing, and transportation. Whether for safety, efficiency, or environmental monitoring, understanding how these sensors work is essential. This FAQ is designed to address common questions about the functionality, applications, and benefits of gas sensors. From detecting hydrogen and methane to integrating sensors into existing infrastructure, our goal is to provide clarity on how this technology can help meet industry needs for real-time, accurate gas analysis and control.

What gases can Fast Sense sensors detect?

Our sensors detect hydrogen (H₂) and methane (CH₄) with high precision, making them ideal for applications where mixed gases are present. These sensors are 100x more compact and 20x lower in cost than traditional solutions, offering an efficient, scalable alternative.

How do Fast Sense sensors help in mixing process control?

In applications where hydrogen is blended with natural gas (typically up to 2% H₂ by law, like in EU), our sensors ensure the blend remains within the safe limit by continuously monitoring the gas composition. This is critical for safe, efficient distribution and combustion processes.

What technology is used to measure energy content at redelivery points?

The sensors quantify gas energy content through real-time HHV/LHV (higher/lower heating value) measurements. This technique, combined with “homogeneous areas” sampling, ensures that utility companies can provide sensor accurace billing for gas usage at redelivery points.

What contaminants can these sensors detect during underground hydrogen extraction?

During underground hydrogen extraction, contaminants such as H₂O and soluble particles must be removed before reintegration into the grid. Our sensors can accurately detect these contaminants, ensuring the gas is purified, with post-treatment pressures around 70 bar and temperatures reduced to 20-30°C.

Are Fast Sense sensors suitable for hydrogen leak detection for pipeline detection units?

Yes, our sensors detect hydrogen leaks within 5 seconds, providing quick, accurate feedback to minimize safety risks in hydrogen production, storage, and transport. Their low power consumption makes them ideal for continuous use in safety-critical environments.

What makes Fast Sense sensors suitable for smart gas meters?

Fast Sense sensor’s are small size (100x more compact than traditional sensors), low power consumption (25x less), and high precision allow for seamless integration into smart grid meters, ensuring real-time gas composition and energy content measurements for both residential and commercial use.

How accurate are Fast Sense sensors in detecting hydrogen and methane blends?

Fast Sense sensors offer highly accurate detection, even in low-concentration H2 and methane blends. The real-time sensing technology ensures precision within 5 seconds, making them suitable for continuous monitoring in dynamic environments.

How is flow meter measurement corrected using sensors?

H2’s lower molecular weight can affect traditional flow meters. By detecting the exact percentage of hydrogen in the blend, our sensors enable real-time flow meter correction. This ensures that the same level of sensor accuracy is maintained for gas delivery, crucial when using gas chromatographs or quality analyzers.

Can Fast Sense sensors monitor hydrogen in underground storage?

Yes, our sensors are designed to handle the challenging conditions of underground hydrogen storage, where gases can reach pressures of 220 bar and temperatures of 50°C. They track hydrogen concentrations from 6% to 90% and help ensure safe extraction and reintegration into the grid after treatment.

What are the typical applications of sensors in industrial environments?

Our sensors are versatile and can be used in hydrogen leak detection, gas analyzers, combustion control, and fuel cell technology. Their compact design and high sensitivity make them suitable for a wide range of industrial processes. Industries such as energy, transportation, HVAC, digital health, & industrial plants

How do Fast Sense sensors assist in energy network monitoring?

Our sensors provide real-time monitoring of hydrogen-methane gas mixtures in energy grids, ensuring optimal blending, minimizing losses, and maintaining efficiency. Their high sensitivity and fast response time make them perfect for grid-wide monitoring solutions.

Do Fast Sense sensors experience cross-sensitivity with other gases?

No, our sensors are designed with advanced selectivity to minimize cross-sensitivity, meaning they accurately detect target gases like hydrogen and methane even in the presence of other gases, improving the reliability of the readings.

What role do Fast Sense sensors play in HVAC systems?

Fast Sense sensors monitor air quality and detect leaks in hydrogen or methane-powered HVAC systems. With their real-time detection capabilities, they enhance system safety and efficiency by ensuring leaks are identified before causing damage.
