High-Pressure Hydrogen Tank Testing | Department of Energy

High-pressure tanks (3,600 psi) have been used safely in compressed natural gas vehicles (NGV) for many years. Improved versions of these tanks made of high-strength composite materials are now used to store hydrogen at higher pressures (5,000 and 10,000 psi) to achieve greater driving range in hydrogen-fueled vehicles.

Blast wave from a high-pressure gas tank rupture in a fire: Stand-alone and under-vehicle hydrogen tanks …

The use of the ideal gas equation of state in the former models significantly overestimates the mechanical energy of the compressed gas, e.g. by 64% for hydrogen storage pressure of 100 MPa. The former techniques without combustion are unable to reproduce blast wave decay in the experiments with high-pressure hydrogen tanks …

The fast charging process of high-pressure gas storage cylinders is accompanied by high temperature rise, which potentially induces the failure of solid materials inside the cylinders and the underfilling of the cylinders. A two-dimensional (2D) axisymmetric model simulated the charging process of hydrogen storage cylinders with a …

High-pressure Storage Vessels for Hydrogen, Natural Gas and Hydrogen-Natural Gas Blends

The H2 partial pressure in 200 bar Hythane falls below the limits in ISO 11114-4, so any certified 9809-1 steel cylinder is OK for Hythane. The abundance of natural gas HE poisons in Hythane makes HE impossible at ambient temp. Coal gas (>30% H2) is a precedent for allowing Hythane in steel cylinders.

Current vehicles are mainly constituted by high pressure storage tank systems, and the structure of hydrogen storage system must be simple and reliable for charging and discharging hydrogen gas. There are four high pressure hydrogen storage tank structures, as shown in Fig. 2 .

Pressure analysis on two-step high pressure reducing system for hydrogen fuel cell electric vehicle …

The energy density requirements of these vehicles are fulfilled via high-pressure gaseous hydrogen storage; therefore, an effective pressure-reducing system is necessary. In this work, a novel multistage pressure-reducing valve (named as T–M valve) combining a sleeve pressure structure valve and a Tesla-type orifice valve is proposed.

Compressed-air energy storage

Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks. In order to retain the energy stored in compressed air, this tank should be thermally isolated from the environment; otherwise, the energy stored will …

Another method is to use glass microspheres that are first filled with hydrogen at high pressure of around 350–700 bar at 300°C, followed by rapid cooling at room temperature. The spheres are then transferred to the low pressured vehicle tank and are reheated again at 200–300°C for controlled release of hydrogen.
