Hydrogen Hydraulic Compression System for Refuelling Stations

Abstract

The article investigates the properties and potential of compressed hydrogen as one of the most promising energy carriers in order to facilitate the development of energy storage capabilities and lay down a stable foundation for the future of a sustainable energy sector. The study considers the use of hydrogen, compressed at high pressure from 50 MPa to 100 MPa, at refuelling stations to supply electric cars. The technical properties of modern hydraulic compressors used for hydrogen accumulation in high pressure buffer containers are considered. The study shows that the design of hydraulic compressors in terms of their technical characteristics optimally corresponds to the primary requirements for their use as booster compressors at refuelling stations. The authors conclude with the proposal of an enhanced design of the hydraulic compressor with the use of fluid flow counters in a control system of a hydrogen compression cycle. The proposed technical solution provides for continuous monitoring of the hydrogen compression process that increases the reliability of control system operation.

Axial Flux Switching Permanent Magnet Alternator with External Magnetic Cores

“…The magnetic circuit of the alternator inductor, proposed by the authors in the design [19], contains two groups of open magnetic circuits made of laminated silicone steel, on the rods of which armature windings are located. The external magnetic circuit of the inductor is made in the form of a magnetic bridge made of structural steel, which forms a magnetic circuit that connects the PM with OMC.…”
