There is a growing requirement for hydrogen to be compressed to pressures up to 10,000 psi or greater for fuel cell vehicle (FCV) refueling. The major aims are to up-scale the laboratory prototype metal-hydride compressor (MHC) developed under ATLAS-H2 and to evaluate the pilot scale, precompetitive MHC implemented in a complete renewable energy storage system. However, high-pressure oxygen (typically above 3 MPa) is a severe safety concern and difficult to implement in a technical process.
For differential pressure operation a compression behavior close to the isothermal values are observed up to 35 MPa. Manufacturer of oxygen, hydrogen & nitrogen gas compressors & gaseous diaphragm pumps designed for continuous use. Do not attempt liquid or compressed gas storage, it is just asking for trouble.
As one of the leading suppliers of state-of-the-art electrolysis systems for the chlor-alkali industry, Uhde was chosen to completely replace an antiquated diaphragm technology with modern, Get More Information energy-efficient membrane technology. 6 is a schematic circuit design for a two-stage electrochemical hydrogen compressor system according to the invention.
However, the production, purification, and compression of hydrogen represent key technical challenges to the implementation of a hydrogen economy, especially in the transportation sector where on-board storage of pure hydrogen may require compression at pressures up to 12,000 psi.
14 is a graph showing the results of dual-stage, electrochemical hydrogen compression to 75 psia (T=22° C.). In a steel plant a Diaphragm Compressor of type MV 4543 II is used for storage of hydrogen in Poland. Compressors are also suitable for eliminating leakages in cryogenic applications.
Data for gas pressures up to 100 MPa is modeled, based on experimental results up to 5 MPa, of the three pressure concepts and validated with literature data up to 70 MPa. RIX offers industrial grade hydrogen compressors. Electrochemical hydrogen compression is a potentially high efficient, low-maintenance and silent technology to produce high pressure hydrogen.
In March of 2013, it was stated by Mr. Bill Elrick of the California Fuel Cell Partnership that one of the hindrances to deployment of fuel cell electric vehicles (FCEVs) is the lack of standardization and codes.1 The U.S. Department of Energy states, It is projected that the current state of hydrogen compressor technology will not be able to meet future infrastructure demands in a cost-effective manner."2 Research is being done to solve problems related to hydrogen compressors.2, 3, 4 So hydrogen compressor design is still in its early stages.
Manufacturer of screw compressors that are available as oil-free machines in various sizes, single & multi-stage, high pressure, & suitable for dry & clean compression of air & neutral gases for a wide variety of applications including: pneumatic transport, aeration of sewage basins, vacuum generation in glass industry, keeping seas & harbours free from ice, construction of oil traps, gas-air mixing plants, production of medicine, stationary unloading of silo vehicles, beverages industry, chemistry & petrochemistry.
Medium pressure compressors are available in discharge pressure ranging from 7 psig to 40 psig. Take profit of our know-how in planning and construction of special systems, e.g. natural gas stations, biogas compressors for industrial large-scale plants, hydrogen systems and energy storage.
The gas is compressed in the cylinder by the up-and-down motion of the liquid column, similar to the reciprocating motion of an ordinary piston. Manufacturer of CNC (compressed natural gas), ethylene, helium, oxygen, hydrogen and nitrogen standard gas compressors.
If there are any carbon atoms in the metal matrix then hydrogen which penetrates the metal will bind to them to form methane and that adds internal pressure to the metal itself, further weakening it. The two-part study consists of station design and performance testing of a commercial-off-the-shelf electrochemical hydrogen compressor.
