Hydrogen Instllation Project

in conclusion, we have a standard approach for using Hydrogen, and we have our approach, which is more strict to provide a fully isolated system. Also, providing a safe environment is the main priority of the project, and the main concern was to make sure that is the work environment is safe. Moreover, I would like to compare standards recommendations and our approach for more enhanced safety measures in this summary.

Standards Recommendations

According to all international standards and UK standards, they advise us to have an excellent ventilation system inside the building as hydrogen leakage is inevitable. Also, for hydrogen bottles, they advise us to follow the standards, keep all storage bottles in the safe area, and provide a good ventilation system with a three to eight meters safe distance. Regarding hydrogen detection, the standards recommend using multiple sensors in the building or protecting the hydrogen leakage. For hydrogen piping, the main recommendation is to keep the line at a certain distance away from that flammable sources and use specific certificate materials.

our approach

Starting from Having zero Hydrogen storage, isolate the hydrogen operation bottles with fire-resistance brick walls from three sides. Then isolating the hydrogen 6 mm line with a U shape metal structure for no fire jets in different angles creates an offset to the building for no attachments between the jet leakage and the building surface. Consider the outside media by changing the line height to avoid any interactions with ground risks, isolating the exhaust line for extra safety, and adjusting the shutdown system to purge the whole line and keep the outside line empty. Inside the building adopting the double piping system because minimising the risk of having Hydrogen was not enough, and we prefer the complete isolation technique. Also, double the system sensitivity by using the vacuum system that reacts to any pressure loss to ensure that the double piping is isolated to the test cell environment. Designing the automatic shutdown system to run in case of emergency or system failure makes no chance to have the hydrogen gas leakage without running the nitrogen purging system or even without having any Hydrogen leakage the system can run in case of double pips leakage or case of any system failure. Finally, add extra sensors with High-speed vulvae to trace and isolate the system in case we have Hydrogen leakage inside the engine and connected to the automatic shutdown system.
