Hydrogen is difficult to store due to its low volumetric energy density. Low temperatures are required to stop the liquid hydrogen from boiling off back into a gas, which occurs at -252.8C. With a lower ignition energy than petrol or natural gas, hydrogen has a wide range of flammable concentrations in the air meaning that ventilation and leak detection are important for hydrogen systems. Whether you need help solving quadratic equations, inspiration for the upcoming science fair or the latest update on a major storm, Sciencing is here to help. The preferred design for Hydrogen applications is a diaphragm compressor. Unlike conventional filling stations, hydrogen is sold by the kilo, not by the litre, and the refuelling time for a conventional bus - which usually has a capacity of between 30 and 37.5 kilos - is no more than 12 minutes. Gaseous Hydrogen Compression | Department of Energy Use an external pump to push the gas into the compressor since the compressor itself sucks the gas from the inlet into its hydraulic pump. Hydrogen compression -An integral part of the H value chain. A patent is pending claiming an exergy efficiency of 70 to 80% for pressures up to 10,000 psi or 700 bars. Power on the diaphragm compressor then watch the pressure gauge move and when the reading is 800 bars, turn the compressor off. Compressed Hydrogen Gas Storage Pressurized Tanks Technology Solutions Note -- transferring compressed gas from the storage tank to the vehicle engine causes slight loss in its compression energy (see reference 5). Hydrogen can be stored cryogenically in a liquid form. The electrochemical compressor works similar to a fuel cell, a voltage is applied to the membrane and the resulting electric current pulls hydrogen through the membrane. You can get Hydrogen from simple means such as passing a current through water, reacting an acid with zinc or extracting it from fossil fuels (see reference 4). For example, stations being deployed to dispense hydrogen into medium- and heavy-duty fuel cell vehicles are expected to compress the hydrogen to 350700 bar pressure and dispense at up to 10 kg/min. Bullet test where live ammunition is fired at the tank. What are the Requirements for Compressors used in Hydrogen Applications? Unlike with batteries, this energy is not lost over time and can therefore be produced and stored on an industrial scale as part of a green energy mix. Buses typically have 5 tanks of 7.5 kg each at 350 bar, for a total of 37.5 kg of hydrogen. Sundyne utilizes the latest technology in solids modeling and FEA analysis to ensure that all working components are designed & tested to minimize wear, improve sealing and reduce corrosive & erosive effects. Hydrogen gas is highly flammable and burns with an almost colorless flame that could cause accidental fires and you should therefore handle it with caution (see reference 3). [7] Used in hydrogen stations. Approximate maximum pressure: 1,000 bars (100MPa; 15,000psi). Today, hydrogen is transported from the point of production to the point of use via pipeline and over the road in cryogenic liquid tanker trucks or gaseous tube trailers. Hydrogen gas storage typically requires the use of high pressure tanks (350-700 bar or 5000-10,000 psi), while liquid hydrogen storage requires cryogenic temperatures to prevent it boiling back into a gas (which occurs at 252.8C). Every process-contacting part in a Sundyne compressor is made from corrosion resistant alloys, making them ideal for hydrogen processing, as well as other applications involving hazardous gasses.
