Hydrogen Compression and Refueling: Insights from Total Hydrogen Solutions
In the quest for sustainable energy, hydrogen stands out as a promising alternative. At the forefront of this innovation is Total Hydrogen Solutions, where Greg Heller, a passionate advocate for climate tech, leads efforts in hydrogen compression and refueling technologies.
In a recent Hyfinder Tech Talk, Greg provided an in-depth look at their cutting-edge systems, highlighting the importance of efficient hydrogen management in clean energy mobility.
What is Hydrogen Compression?
Hydrogen compression is a critical process that involves increasing the pressure of hydrogen gas to make it suitable for storage and use in various applications. As Greg Heller explains, “In simplest terms, it’s any system that’s compressing hydrogen, taking it from a lower pressure going to higher pressure.” This process is essential for efficiently storing hydrogen and ensuring it can be used effectively in fuel cells and other applications.
During the tech talk, Greg showcases an electrolyzer system where hydrogen is produced at low pressure, about 30-35 bar. Then, it is stored in a buffer tank until it is compressed to higher pressures, up to 700 bar, through pneumatic boosters. It is compressed for storage or vehicle refueling. Watch Greg explain the compression process.
Components of a Hydrogen Compression System
A typical hydrogen compression system includes several components, each playing a vital role in the process. Greg highlighted the roles of different compressors, such as diaphragm and booster compressors, in handling varying pressure and flow requirements. By tailoring the compressor choice to the specific needs of each application, businesses can achieve better efficiency, reduce costs, and enhance overall system reliability.
Greg also emphasized the importance of automation and safety in these systems, stating, “there’s a lot of automation here as well… it could be set to go on its own essentially for quite a while.” This automation ensures that the system operates efficiently and safely, preventing over-pressurization and other potential hazards. See Greg walk through the system components and compression combinations.
Applications of Hydrogen Compression
Hydrogen compression systems are versatile and can be used in various scenarios. One common application is in hydrogen refueling stations. Greg mentioned, “this is the system we built for our customer… a compact hydrogen refueling station… to fill a Toyota Mirai.” These systems are designed to handle different pressure levels and ensure that vehicles can be refueled quickly and safely.

Beyond refueling, hydrogen compression is also used in large-scale hydrogen production facilities. Greg noted, “for a large electrolyzer, hydrogen production… we’re starting at very low pressures. We have high compression ratios.” This highlights the importance of compression in managing the flow and storage of hydrogen in industrial settings.

Safety Considerations
Safety is a paramount concern in hydrogen compression systems. Total Hydrogen Solutions uses advanced mechanical and solenoid valve systems to ensure safe venting and isolation in the event of electrical or mechanical failures.
Greg emphasized the importance of selecting the right components and having multiple points of backup. He stated, “selecting the right components is really big… and making sure you have multiple points of backup.” This ensures that the systems are not only efficient, but also safe to operate.

The Future of Hydrogen Technology
Looking to the future, Greg expressed optimism about advancements in hydrogen technology. The development of more cost-effective catalysts and higher energy density in hydrogen storage solutions could drive down costs and improve the scalability of hydrogen systems.
He highlighted the growing interest in hydrogen production and consumption, noting the importance of a holistic approach to system design. By balancing storage and compression needs, companies can optimize costs and efficiency. Greg shared, “I’m seeing a whole bunch of interest on different types of hydrogen production… and systems.” Hear Greg’s thoughts on the future at 19:40 in the video.
