Q: Is your storage a high pressure cylinder? A: Actually no - our storages are charged at pressures 10-35 bar, but they are operating at pressures below 10 bar. However the bodies of our tanks can stand pressure over 100 bar. Q: Is your tank a gas storage? A: No, in our storage hydrogen is stored in the form of solid metallic hydride. Q: How do I know when I used up hydrogen and need to recharge it? A: If the pressure in the storage dropped below 1.5 bar (at room temperature) you need to recharge it. Q: Shall I add pressure gauge on your storage? A: No, except you need to record pressure in your experiments. Q: Can your storage store other gases? A: No, our cylinder is storing only hydrogen. Q: What will happen if your storage is charged with other gases? A: It will work just as a high pressure tank. However, if the stored gas (CO, oxygen, etc.) can react with the storage alloy, the storage will lose its original function. Q: Is a regulator required while using H Bank hydrogen storage system? A: Since the pressure in our storage remains almost constant until 95% of the gas is used, no regulator is needed. Q: How long does it take to charge the H Bank System? A: Recharging is simple and fast for our systems. For example, it only takes about 30 minutes to charge a 50 liters canister at ambient air or just 10-15 minutes if room temperature water bath is used. Q: How long is the lifespan of the H Bank system? A: If charged with 99.99% or higher purity hydrogen, the charge/discharge recycling life of our system can be over 3000 cycles with less than 10% decay in storage capacity. In fact, if you recharge our storage every day you can use it for more than 8 years. The bodies of our tank canisters are made from high-grade low carbon SS361L stainless steel or SS321 stainless steel, which ensures the system’s necessary strength as well as prevents it from oxidation related negative effects. System’s complete stainless steel construction allows increasing designed maximum gas flow rate while using hot water bath.
