Cryo-Compressed Hydrogen considered a viable solution to problems concerning hydrogen storage; Cryomotive aiming for commercialization.
Here’s an article posted in Composites World.
According to the article,
- Cryo-Compressed Hydrogen (CcH2): A storage solution for hydrogen at cryogenic temperatures in a pressurized vessel, typically at 250-350 atm
- Storage Tanks: Cryomotive is commercializing CcH2 storage tanks and refueling stations (HRS) for trucks and commercial vehicles
- Cost: Cost may ultimately determine the expansion opportunities of hydrogen technologies into the composites industry
So what are the advantages of CcH2 which explains why researchers and companies are exploring this technology?
- High Energy Density: CcH2 combines the benefits of both compressed and liquid hydrogen, leading to a higher volumetric energy density compared to conventional hydrogen storage methods. This makes it particularly suitable for larger vehicles that require high energy and long-range capabilities.
- Lower Storage Pressure: CcH2 operates at lower pressures (up to 350 bar) compared to compressed hydrogen gas (CGH2), which typically requires pressures of up to 700 bar. This reduction in pressure can lead to lower production and material costs, as the structural requirements for the storage tanks are less demanding.
- Long Dormancy Times: CcH2 systems exhibit long dormancy periods without significant hydrogen loss, minimizing the risk of boil-off during extended periods of inactivity. This is an advantage over liquid hydrogen systems, which can experience losses due to evaporation.
- Flexible Refueling Options: CcH2 storage systems can be refueled using various methods, including cryo-compressed liquid hydrogen and compressed gaseous hydrogen. This flexibility enhances the refueling infrastructure, making it easier to integrate with existing systems.
- Compatibility with Different Fuel Systems: CcH2 can supply sufficient pressure for both fuel cells and hydrogen combustion engines, making it versatile for various applications in transportation, including heavy-duty trucks and potentially aviation.
- Cost-Effectiveness: The overall cost of CcH2 systems can be lower than that of traditional hydrogen storage solutions, potentially offering a total cost of ownership that is competitive for both vehicle operators and hydrogen refueling stations.
