“…Compared to pure Pd sensitive material, it effectively improved the sensor’s response to hydrogen time. Recently, self-referenced demodulating methods of fiber optic hydrogen sensors based on WO 3 -Pd 2 Pt-Pt composite film were studied (Yang et al , 2018). By using the proper baseline intensity as sensing parameters, fluctuations of the sensing signal of the hydrogen sensor can be obviously depressed, and sensitivity can be greatly improved.…”

Purpose With the acceleration of global energy structure transformation, hydrogen has been widely used for its non-pollution and high efficiency, and hydrogen detection is used to guarantee the hydrogen safety. The purpose of this paper is to study the research foundation, trend and hotspots of hydrogen detection field. Design/methodology/approach A total of 4,076 literature records from 2000 to 2021 were retrieved from the core collection of the Web of Science database selected as data sources. The literature information mining was realized by using CiteSpace software. Bibliometrics was used to analyze information, such as keywords, authors, journals, institutions, countries and cited references, and to track research hotspots. Findings Since the 21st century, the number of publications in the hydrogen detection field has been in a stable stepped uptrend. In terms of research foundation, the hotspots such as core-shell structures, nano-hybrid materials and optical fiber hydrogen sensors have been studied extensively. In combination with the discipline structure and research frontier, the selectivity, sensitivity, response speed and other performance parameters of hydrogen sensors need further improvement. The establishment of an interdisciplinary knowledge system centered on materials science and electronic science will become a long-term trend in the research of hydrogen detection. Originality/value This study presents an overview of research status, hotspots and laws in hydrogen detection field, through the quantitative analysis of much literature in the field and the use of data mining, so as to provide credible references for the research of hydrogen detection technology.

“…A new device architecture that incorporates fiber gratings into the optical fiber provides significant reduction in the detection limit. 105 Combining a fiber grating that is insensitive to H 2 with an H 2 sensitive mirror enables the ability to account for changes in the intensity of the light source. This architecture is simpler to fabricate, and greatly increases accuracy by minimizing uncertainty attributable to light source fluctuations.…”

Decarbonization of the energy system is a key aspect of the energy transition. Energy storage in the form of chemical bonds has long been viewed as an optimal scheme for energy conversion. With advances in systems engineering, hydrogen has the potential to become a low cost, low emission, energy carrier. However, hydrogen is difficult to contain, it exhibits a low flammability limit (>40000 ppm or 4%), low ignition energy (0.02 mJ), and it is a short-lived climate forcer. Beyond commercially available sensors to ensure safety through spot checks in enclosed environments, new sensors are necessary to support the development of low emission infrastructure for production, transmission, storage, and end use. Efficient scalable broad area hydrogen monitoring motivates lowering the detection limit below that (10 ppm) of best in class commercial technologies. In this perspective, we evaluate recent advances in hydrogen gas sensing to highlight technologies that may find broad utility in the hydrogen sector. It is clear in the near term that a sensor technology suite is required to meet the variable constraints (e.g., power, size/weight, connectivity, cost) that characterize the breadth of the application space, ranging from industrial complexes to remote pipelines. This perspective is not intended to be another standard hydrogen sensor review, but rather provide a critical evaluation of technologies with detection limits preferably below 1 ppm and low power requirements. Given projections for rapid market growth, promising techniques will also be amenable to rapid development in technical readiness for commercial deployment. As such, methods that do not meet these requirements will not be considered in depth.

“…Optical hydrogen sensors based on different working principles have been developed over the last 40 years, like interference sensors, 1-5 micro-mirror sensors, [6][7][8] evanescent sensors, 9-14 surface plasmon resonance (SPR) sensors, [15][16][17][18] and fiber grating sensors. [19][20][21][22][23][24][25][26] In this paper, an evanescent wave hydrogen sensor, based on a fiber Bragg grating (FBG) coated with Pd nanoparticles, is presented. Pd is commonly used as functional sensor material, enabling the selective detection of hydrogen.…”

Hydrogen has attracted much attention as a source of clean and sustainable energy. However, one of the drawbacks of handling hydrogen as a power source is its volatility and flammability. Moreover, hydrogen leakages in gas pipelines or tanks can generate highly explosive gas mixtures in air, if the hydrogen concentrations exceed 4 %. Therefore, in order to increase the security, monitoring of hydrogen concentrations in hydrogen infrastructures is mandatory. Remote sensing systems using passive fiber optical sensors are predestined for these kinds of applications. In this paper, a sensor based on evanescent field fiber Bragg grating (FBG), coated with palladium (Pd) nanoparticles is proposed. Thereby, the intensity change of the sensor signal correlates with the hydrogen concentration. The detection range of the sensor is between 0.5% to 5% H2 in nitrogen or synthetic air atmosphere and therefore shows great potential for the detection of hydrogen leakages below the explosive limit of 4%.
