Pioneering Aerial Natural Hydrogen Detection: Xcalibur Smart Mapping’s Breakthrough with Raman LiDAR Technology
As a global leader in airborne geophysical solutions, Xcalibur Smart Mapping is at the forefront of innovative resource detection technologies, including natural hydrogen exploration. Leveraging advanced technologies, Xcalibur is developing industry-first approaches to map and quantify hydrogen emissions remotely—an essential step as hydrogen grows in importance for sustainable energy.
Hydrogen, while the most abundant element in the universe, remains challenging to detect on Earth due to its tendency to disperse rapidly in the atmosphere. This trait complicates efforts to locate naturally occurring hydrogen reservoirs. Hydrogen is increasingly recognised as a vital component of the clean energy future, especially in countries like Australia, where over $225 billion in hydrogen-related projects are projected. Unlike hydrogen produced through electrolysis or steam reforming, natural hydrogen has the potential to offer a lower-cost, environmentally friendly alternative by using existing subsurface reservoirs.
Challenges in detecting natural hydrogen
The difficulty in detecting natural hydrogen stems from the limitations of traditional methods, which require direct contact with hydrogen gas of a sufficiently high concentration. For airborne geophysical surveys, where direct sampling is impractical, the challenge becomes even greater.
Xcalibur Smart Mapping has partnered with Curtin University to overcome this obstacle by developing a stand-off hydrogen detection system based on Raman LiDAR technology. This groundbreaking approach can detect low concentrations of hydrogen emissions from an airborne platform, enabling the identification of seepage areas and providing new insights into subsurface hydrogen dynamics.
Innovative application of Raman LiDAR technology
At the core of this initiative is the use of Raman LiDAR (Light Detection and Ranging), a laser-based remote-sensing instrument designed for active detection of hydrogen at a distance. Raman LiDAR works by emitting a laser that excites the molecular bonds of gases, such as hydrogen, in the atmosphere. These molecules then scatter light at unique wavelengths, which the spectrometer captures and analyses to determine the presence and concentration of hydrogen. This technique allows for the precise detection of hydrogen emissions without direct contact, making it ideal for aerial surveying.
Andrew Lockwood, Xcalibur’s Senior Research Scientist, has been leading this effort in collaboration with Professors Charles Ironside and Mervyn Lynch at Curtin University. Lockwood, who brings extensive experience in industrial gas monitoring, describes this project as an opportunity to push the boundaries of applied physics within geophysical research. According to Lockwood, “This collaboration allows us to advance a practical application of Raman LiDAR for identifying hydrogen emissions remotely—a tool that could transform both hydrogen exploration and environmental monitoring.”
A world-first achievement: 3D mapping of hydrogen plumes
In a recent development, Xcalibur Smart Mapping’s R&D team successfully conducted a 3D mapping of a hydrogen plume using their Quantum Raman Spectrometer in a controlled lab setting. Traditional methods, such as electrochemical sensors, require sampling hydrogen directly, but the Raman Spectrometer prototype detects hydrogen at a distance, making it far more suitable for field operations. This breakthrough marks a pivotal step forward in airborne hydrogen detection, offering an efficient and scalable approach to map hydrogen concentrations across large areas.
Understanding hydrogen dispersion remains a critical factor in this technology’s effectiveness. Xcalibur’s research team has developed theoretical models to predict hydrogen dispersion under varying atmospheric conditions. These models allow for more accurate interpretation of airborne data, supporting a detailed assessment of hydrogen sources during real-world surveys. This capability is essential in places like the Mali Borefield, where hydrogen production at commercial levels requires consistent and precise monitoring.
Expanding the potential for commercial applications
The implications of these advancements extend beyond hydrogen exploration alone. As hydrogen infrastructure—encompassing generation, storage, and transportation—becomes more prevalent, the demand for reliable leak detection technologies will grow. The Raman LiDAR system developed by Xcalibur Smart Mapping provides a unique solution: a stand-off detection method that can identify hydrogen leaks over large areas before they pose a safety risk. The ability to survey extensive zones from the air, ensuring early detection and containment, positions Xcalibur as a valuable resource for clients involved in hydrogen production and distribution.
As Teo Hage, Xcalibur’s Vice President of Technology, explains, “Raman LiDAR will consolidate our technological lead in hydrogen exploration, allowing us not only to detect natural hydrogen in subsurface reservoirs but also to monitor infrastructure for potential leaks. The rapid expansion of both applications highlights the commercial opportunities and industry demand for these advancements.”
Towards a sustainable hydrogen economy
As hydrogen continues to gain traction as a critical energy source, the role of natural hydrogen could be transformative in accelerating the green transition. By focusing on technologies that enable effective detection and monitoring, Xcalibur Smart Mapping is helping to unlock this potential. With the combination of Raman LiDAR and other geophysical tools, Xcalibur is positioned to offer comprehensive hydrogen solutions that address both exploration and operational needs.
The outcomes of this partnership with Curtin University are expected to shape the future of natural hydrogen detection, with Xcalibur Smart Mapping actively working to refine and expand its capabilities in this area. This initiative underscores the company’s commitment to developing practical solutions that align with evolving energy needs while upholding high standards of environmental responsibility.
