Supporting the North American Hydrogen Industry

The Future of Hydrogen

The hydrogen industry is becoming increasingly important due to the growing global demand for clean energy and the need to reduce greenhouse gas emissions. Hydrogen is a versatile energy carrier that can be produced from a variety of sources, including renewable sources such as wind and solar power, as well as natural gas and other fossil fuels.

While hydrogen is a clean and versatile energy carrier, it does pose some potential dangers that must be carefully managed. Hydrogen damage can occur in a variety of ways, but a common form is hydrogen embrittlement, which is the result of hydrogen atoms diffusing into the metal lattice of a material and causing it to become brittle and prone to cracking or failure. Hydrogen embrittlement can occur during the manufacturing process, during storage, or during use of materials in hydrogen environments.

To prevent hydrogen damage, materials and components must be designed and manufactured to withstand the effects of hydrogen exposure. This can involve using materials that are less prone to hydrogen embrittlement, applying protective coatings or barriers to prevent hydrogen diffusion, or using nondestructive testing techniques to detect hydrogen damage before it leads to failure.

Visual Inspection

Visual Inspection

Acuren inspectors can aid with hydrogen equipment any stage of the asset lifecycle. Acuren inspectors can act as Owners Inspectors or QA/QC during new construction projects to ensure compliance with applicable codes/standards, specifications, and regulations.

Visual inspectors are responsible for inspecting hydrogen infrastructure, to ensure that they are in good condition and free from defects or damage. Our inspectors are experienced with hydrogen damage mechanisms; they know where to look and what technologies to deploy. We can create inspection plans to ensure your equipment will be inspected thoroughly, both on-stream and during maintenance outages.

Nondestructive Testing (NDT)

Nondestructive Testing (NDT)

Nondestructive Testing (NDT) techniques play a critical role in the acceptance of new construction, fabrication and installation of assets as well as detection of in-service damage in the hydrogen industry. Starting with basic methods and progressing to advanced techniques, NDT helps identify early-stages of hydrogen damage to ensure the safe and efficient operation of hydrogen assets.

The synopsis outlines the evolution of NDT techniques in the hydrogen industry, from conventional methods to advanced ultrasonic techniques for early-stage HTHA detection.

Conventional Methods: Basic NDT techniques, such as visual inspection, magnetic particle testing, and liquid penetrant testing, are commonly used to detect surface-level damage in hydrogen-related equipment, such as pipelines, vessels, and valves. These methods are simple and cost-effective but are limited to surface defects and may not be suitable for detecting internal or subsurface damage.

Radiographic Testing (RT): RT is a widely used NDT technique in the hydrogen industry that involves the use of X-rays or gamma rays to penetrate materials and detect internal defects. RT is effective in identifying volumetric defects, such as cracks, voids, and inclusions, and provides detailed images for further analysis. However, it requires the use of radioactive sources, specialized equipment, and trained personnel, making it more complex and costly compared to conventional methods.

Ultrasonic Testing (UT): UT is a versatile NDT technique that uses high-frequency sound waves to detect internal and subsurface defects in hydrogen-related components. UT can be used to measure wall thickness, detect cracks, and identify other types of damage, including HTHA. Advanced UT techniques, such as phased array ultrasonic testing (PAUT) and time-of-flight diffraction (TOFD), provide higher resolution and faster inspection capabilities, making them suitable for detecting early-stage HTHA in high-temperature hydrogen environments.

Eddy Current Testing (ECT): ECT uses electromagnetic induction to detect surface and near-surface defects in conductive materials. ECT is particularly useful in detecting corrosion-related damage, stress corrosion cracking (SCC), in hydrogen-related equipment. ECT is fast, reliable, and does not require the use of radiation, making it a preferred method for in-service inspections.

Advanced Ultrasonic Techniques for Early Stage Hydrogen-Induced Cracking (HIC) and HTHA Detection: Advanced ultrasonic techniques such as Phase Coherence Imaging (PCI), Total Focus Method (TFM), Full Matric Capture (FMC) Time of flight diffraction (ToFD), velocity ratio measurement and Phased Array Ultrasonic testing (PAUT), are emerging as effective methods for early-stage HTHA detection in the hydrogen industry. PAUT uses multiple ultrasonic elements to generate and receive beams at different angles, providing detailed images and accurate defect sizing. These advanced techniques offer increased sensitivity and reliability in detecting early-stage HTHA, which is critical in preventing catastrophic failures in high-temperature hydrogen environments.

NDT techniques are vital for detecting in-service damage in the hydrogen industry. Starting with basic methods and progressing to advanced techniques, such as advanced ultrasonic techniques for early-stage HTHA detection, NDT ensures the safe and efficient operation of hydrogen-related infrastructure by identifying defects and damage before they become critical issues.
