“…Hydrogen storage materials on the basis of MgH 2 are characterised by significantly higher weight hydrogen storage densities but require high operating temperatures that limits their application by only several cases when the high-temperature heat source, e.g. SOFC [22,23], is available. 1 These values represent typical hydrogen storage capacities of individual MH containers.…”

In this paper, we present a bibliographical review of tri-generation systems using renewable fuel. These systems are used to produce cold, heat and power from mainly one fuel source. This mode of operation increases overall efficiency and allows better use of the input fuel. Most tri-generation systems use a fuel cell for its reliability and performance. Furthermore, fuel cells produce heat and electricity at a very high efficiency compared to classical systems. A part of produced heat is recovered to produce cold by an absorption cycle when necessary. The fuel cell can be fed by various fuels, including natural gas, hydrogen produced from renewable or biomass gasification. The overall efficiency depends on the configuration and management of the entire system. The optimal sizing of tri-generation systems is a complicated task. It generally requires two optimization algorithms, one to optimize power flows within the system and the other to optimize the size of the elements. The optimal sizing of tri-generation systems requires two optimization algorithms, one to optimize power flows within the system and the other to optimize the size of each element of the system. Between 75 and 95%, efficiency can be attained depending on the choice of production system and energy management strategy. Keywords Tri-generation • Fuel cell • Hydrogen 23.1 Introduction Typically, a tri-generation system produces electricity, heat and cooling from a single source (Fig. 23.1). Products are adjusted to meet the energy demand of a group of residences according to demand. The major advantage of tri-generation is an efficient use of produced energy, lower pollutant emissions and security of supply [11]. Fuel cell technology is integrated into tri-generation systems as it allows better control of

“…Magnesium hydride (MgH 2 ) stands as a promising hydrogen source because of its high hydrogen-storage capacity (7.6 wt%), abundant resources, and low cost ( Grochala and Edwards, 2004 ). The research on applications of MgH 2 and its related compounds has focused on thermal storage for solar power stations and hydrogen supply for vehicles ( Bogdanović et al, 1995 ; Schlapbach and Zuttel, 2001 ; Baricco et al, 2017 ; Lototskyy et al, 2018 ; Hirscher et al, 2020 ). It is well documented that MgH 2 can produce a desired quantity of H 2 by the following hydrolysis reaction at room temperature: MgH 2 + 2H 2 O → Mg(OH) 2 + 2H 2 , the by-product of which is environmentally friendly.…”

Magnesium hydride (MgH2) is a promising solid-state hydrogen source with high storage capacity (7.6 wt%). Although it is recently established that MgH2 has potential applications in medicine because it sustainably supplies hydrogen gas (H2), the biological functions of MgH2 in plants have not been observed yet. Also, the slow reaction kinetics restricts its practical applications. In this report, MgH2 (98% purity; 0.5–25 μm size) was firstly used as a hydrogen generation source for postharvest preservation of flowers. Compared with the direct hydrolysis of MgH2 in water, the efficiency of hydrogen production from MgH2 hydrolysis could be greatly improved when the citrate buffer solution is introduced. These results were further confirmed in the flower vase experiment by showing higher efficiency in increasing the production and the residence time of H2 in solution, compared with hydrogen-rich water. Mimicking the response of hydrogen-rich water and sodium hydrosulfide (a hydrogen sulfide donor), subsequent experiments discovered that MgH2-citrate buffer solution not only stimulated hydrogen sulfide (H2S) synthesis but also significantly prolonged the vase life of cut carnation flowers. Meanwhile, redox homeostasis was reestablished, and the increased transcripts of representative senescence-associated genes, including DcbGal and DcGST1, were partly abolished. By contrast, the discussed responses were obviously blocked by the inhibition of endogenous H2S with hypotaurine, an H2S scavenger. These results clearly revealed that MgH2-supplying H2 could prolong the vase life of cut carnation flowers via H2S signaling, and our results, therefore, open a new window for the possible application of hydrogen-releasing materials in agriculture.
