ТSК-3.5/150

 

ТSК-3.5/150 is a metal hydride thermosorption compressor (MH TSC) for hydrogen compression to low, medium or high pressure.
ТSК-3.5/150 has a modular design allowing to build MH TSCs varying in performance and pressure. All electronic components, as well as the materials used for the implementation of the necessary structures are standardized and mass-produced.

ТСК-3.5/150 is a metal hydride thermosorption compressor (MH TSC) for hydrogen compression to low, medium or high pressure.

ТSК-3.5/150 has a modular design allowing to build MH TSCs varying in performance and pressure. All electronic components, as well as the materials used for the implementation of the necessary structures are standardized and mass-produced.

The process of hydrogen compression in ТSК-3.5/150 is based on the ability of intermetallic compounds of AB5 family to reversibly absorb (exothermic reaction) and release hydrogen (endothermic reaction) at different pressures depending on temperature potential of thermal effect and composition of the intermetallic compound used.

Due to the absence of moving parts, ТSК-3.5/150 has significant advantages compared to mechanical compressors. These include high reliability and safety, simple design, reduced risk of hydrogen leakage and absence of noise and vibration. Moreover, the compressor produces hydrogen of high purity: with no oil contamination as often is the case in mechanical compressors, no moisture or oxygen impurities as in high pressure electrolytes, furthermore, additional purification of hydrogen takes place, as the reaction between the metal phases and hydrogen has a selective nature.

Advantages

  • ·         Absence of moving parts, allowing to simplify the design, to ensure high reliability and virtually eliminate the risk of hydrogen leakage;
  • ·         Elimination of noise and no vibration;
  • ·         The compressor produces hydrogen of high purity;
  • ·         Contamination with lubricants is excluded which often is the case in mechanical compressors;
  • ·         Contamination with moisture and oxygen as in high pressure electrolytes is excluded as well;
  • ·         Reaction of the metal phase to hydrogen is selective, therefore, gas impurities can be removed before desorption at high pressure.
  • ·         It represents both compact and safe hydrogen storage system.
  • ·         The design of the thermosorption hydrogen compressor implemented in ТSК-3.5/150 features a combined thermal cycling scheme.

 

The module ТSК-3.5/150 represents a set of stainless steel tubes arranged horizontally in one plane and filled by metal hydride.

Н2store-1000

Metal hydride hydrogen storage "Store-H2 1000" is intended for the storage, transportation and producing high purity hydrogen gas.
The hydrogen can be used in various technological purposes, in particular for flame ionization gas detectors, flame detectors, ionization and industrial laboratory chromatographs, as well as to provide hydrogen to other devices and systems.


The operating principle of "N2store 1000" metal hydride hydrogen battery based on the special ability of intermetallic compounds react reversibly with hydrogen, i.e. to absorb hydrogen under certain conditions to form a solid metal hydride, and if conditions change again to release hydrogen. Absorption of hydrogen is accompanied by heating of the metal hydride, while hydrogen evolution takes place with heat absorption from the environment and the cooled metal hydride.

 

Terms or absorption of hydrogen evolution depends on the chemical composition of the alloy, hydrogen pressure and temperature. The metal hydride hydrogen battery "N2store-1000" used alloy consisting of lanthanum, nickel, cerium pressure above that at room temperature is 0.2 — 0.4 MPa.
