“…More recently, Moon et al optimized the hydrogen concentration needed to achieve the maximum possible hydrogen storage capacity in moderate thermodynamic conditions. However, despite those promising multiple hydrogen occupancies, the GC (Gas chromatography) results indicated that most of the hydrate cages to be filled either by methane or ethane rather than hydrogen with a composition of (51.74:17.98:30.2) mol% for (CH 4 :C 2 H 6 :H 2 ) in hydrate at the best case [199].…”

Nowadays, the combustion of fossil fuels for transportation has a major negative impact on the environment. All nations are concerned with environmental safety and the regulation of pollution, motivating researchers across the world to find an alternate transportation fuel. The transition of the transportation sector towards sustainability for environmental safety can be achieved by the manifestation and commercialization of clean hydrogen fuel. Hydrogen fuel for sustainable mobility has its own effectiveness in terms of its generation and refueling processes. As the fuel requirement of vehicles cannot be anticipated because it depends on its utilization, choosing hydrogen refueling and onboard generation can be a point of major concern. This review article describes the present status of hydrogen fuel utilization with a particular focus on the transportation industry. The advantages of onboard hydrogen generation and refueling hydrogen for internal combustion are discussed. In terms of performance, affordability, and lifetime, onboard hydrogen-generating subsystems must compete with what automobile manufacturers and consumers have seen in modern vehicles to date. In internal combustion engines, hydrogen has various benefits in terms of combustive properties, but it needs a careful engine design to avoid anomalous combustion, which is a major difficulty with hydrogen engines. Automobile makers and buyers will not invest in fuel cell technology until the technologies that make up the various components of a fuel cell automobile have advanced to acceptable levels of cost, performance, reliability, durability, and safety. Above all, a substantial advancement in the fuel cell stack is required.

“…In terms of stability, gas hydrate structure sI is more stable. However, sI hydrates are rich in methane, and H 2 rich-hydrates result in sII formation, which is less stable at any given temperature and pressure, which is obvious …”

“…The gas compositions were varied to optimize and achieve the most suitable fuel mixtures that resemble the available hydrogen and methane blends. 144 In 2021, Park et al 145 extended their findings to investigate the critical hydrogen concentration in hythane for the formation, storage, and transportation of clathrate gas hydrates. The addition of methane and ethane as a natural gas component in the hydrogen is detrimental to the amount of hydrogen occupancy; however, a slight compromise ensures better hydrate formation conditions and improved hydrate stability for long-term storage.…”

Hydrogen Economy and Role of Hythane as a Bridging Solution: A Perspective Review

2021

View full text Add to dashboard Cite

Molecular hydrogen is the most optimistic solution for achieving a carbon-neutral energy economy, and it requires scientific intervention for its production, storage, and transportation. In the present time, hydrogen is produced primarily from conventional fossil fuels. Hydrogen production from natural gas using partial oxidation and steam reforming processes is a relatively mature process. However, several modifications and improvements are being researched. Hydrogen generation from potential renewable and biological sources such as water splitting and biomass conversion are propitious approaches. Hydrogen is one of the smallest molecules, and the volumetric efficiency of its storage is quite poor. The creative and innovative ways for molecular hydrogen storage, including pressurized, liquified, physically adsorbed, chemically adsorbed, and in the form of gas hydrates, are being investigated. The delay in developing a systematic and mature hydrogen economy is mainly due to challenging storage conditions and the safety aspect of its transportation. Hythane, a patented mixture of hydrogen and natural gas, can act as a bridge for the hydrogen economy by sharing the current natural gas infrastructure. This review delivers an extensive understanding of the properties of hythane fuel with a brief history. Hydrogen addition can increase NO x emissions due to exceptional heat generation that can be solved to a certain extent with the approach of inventive technologies developed for internal combustion engines, including three-way catalyst, lean burn combustion, exhaust gas recirculation (EGR), and direct fuel injection (DFI).
