Hydrogen refuelling station with integrated metal hydride compressor: Layout features and experience of three-year operation

The Influence of Brand Visual Communication on Consumer Psychology Based on Deep Learning

“…From the principle of operant conditioning, the behavioral loyalty to the brand is strengthened, and then, the brand loyalty of consumers is formed [4]. Lototskyy et al conducted an in-depth discussion on the mechanism of brand extension and further expounded consumers' trust and loyalty to the brand's original products from the aspects of learning theory, ratchet effect theory, risk theory, and demand hierarchy theory; through the low-cost transfer of brand extension to extended products, this almost recognized but lacking detailed analysis point of view has been analyzed, which has laid a theoretical foundation for the related research on brand extension [5]. Zhou et al deeply analyzed the characteristics of consumer behavior, as shown in Figure 1, and studied the interaction and role between consumer behavior and brand image building.…”

Thermally driven hydrogen compression using metal hydrides

“…62 Other features of the integrated MH compression systems include proper selection and integration of the auxiliary system components aligned with the operation and service procedures. Analysis of >3 years-long operation and service/upgrade of the MHHC operating in the industrial environment 75 showed that these features mostly influence on compressor's productivity and reliability. Special attention should be paid to avoiding contamination of gas pipelines with very fine powder of the MH material (installation of inline filters in addition to the filters integrated with MH containers), control algorithm (replacing or duplicating the actions which require feedback from pressure sensors by the passive control, eg, by using check or relief valves), as well as possibility of regeneration procedure and its scheduling.…”

“…The duration of complete heating/cooling (H 2 absorption/desorption) cycle between 50 and 60 min provides hydrogen compression productivity up to ~3.5 Nm 3 /h per a container. The containers of this type were used in the development of series of industrial‐scale MHHCs 11,24 including the one operating at a refinery of South African company Impala Platinum 75 (see Section 3).…”

Modelling of metal hydride hydrogen compressors from thermodynamics of hydrogen – Metal interactions viewpoint: Part I. Assessment of the performance of metal hydride materials

“…The data characterising three AB 2 -and six AB 5 -type intermetallic alloys, which were used in the development of industrial-scale MHHC's at the authors' institutions [14,16,20,24,25], are listed in Table 1. Table 1 also presents the most important experimentally measured hydrogen sorption properties of these materials including maximum hydrogen absorption capacity as related to the temperatures and hydrogen pressures, entropy and enthalpy changes during H 2 desorption calculated from the van't Hoff dependencies at the plateau midpoints, as well as the calculated hydrogen compression performances.…”
