Amidst escalating concerns over climate change, the global energy landscape is undergoing a profound transformation towards cleaner, more sustainable alternatives. Liquid Hydrogen (LHy) has emerged as a frontrunner in this endeavor, offering a plethora of applications across diverse industries. What distinguishes these fuels is not just their efficiency and lower emissions but also the pivotal role played by super insulation technology and innovative products from Cryogas-Cryogenic i.e. vacuum jacketed pipes, valve manifold boxes and bulk-fluid loading and off-loading equipments.
The introduction of Cryogas super insulation technology has revolutionized LHy applications, ensuring efficient refueling, vehicle usage, and power generation. This innovation minimizes heat transfer, enabling safe and cost-effective transportation and storage of hydrogen fuel while catering to various energy needs. Our advanced super insulation technology, designed to guarantee the reduction of boil-off-gas (BOG) and improve preservation of your valuable LHy in the pipeline. With an exceptional ability to minimize heat leakage, this technology ensures that pressure buildup remains controlled, safeguarding your assets and minimizing losses to the absolute minimum.
For LHy applications, Cryogas provides option on material of construction with SS316L (1.4404) on top of our standard 304L (1.4301/1.4307). We also provide W-series fully welded pipe connections for leak free, higher level of safety and 80% lower heat leaks than any competitive connection in the market.
Vacuum Jacketed Pipe (VJP)
Cryogas Cryogenic, with prior experience in designing and commissioning several VJP systems for large scale cryogenic facility, bring invaluable expertise to ongoing prototyping and technology development for VJP in LHy application. Our focus remains on enhancing performance, safety, reliability, durability, and maintainability.
Design Features:
The VJP shares a stainless-steel core pipe with conventional PIR/PUR systems but is enclosed within an external pipe in a 'pipe-in-pipe' configuration. The radial gap between the pipes is insulated with multiple layers of highly reflective aluminum foil to minimize radiation heat input. Additionally, this annular space is evacuated to high vacuum and to eliminate heat transfer through conduction and convection.
LHy VJP is equipped with an internal expansion joint (bellows), the LHy VJP enables the core pipe to self-compensate for thermal contractions during normal operation, ranging from room temperature to -253°C (20 K). The jacket pipe experiences environmental temperature fluctuations, from low temperatures during winter nights to elevated temperatures of up to 75°C due to solar heating in summer. Thermal movements in the jacket are minimal and can be safely managed by expansion bellow with rigid pipe supports within allowable design stress limits.
