Decarbonization plays an important role in future energy systems for reducing greenhouse gas emissions and establishing a zero-carbon society. Hydrogen is believed to be promising secondary source (energy carrier) that can converted, stored, utilized efficiently, leading broad range of possibilities applications. Moreover, hydrogen electricity are mutually creating high security economic opportunities toward resilience. stored various forms, including compressed gas, liquid hydrogen, hydrides, adsorbed reformed fuels. Among these, has advantages, gravimetric volumetric densities purity. However, garnering increasing attention owing the demand long storage periods, transportation distances, performance. This paper reviews characteristics liquefaction technology, methods, safety standards handle hydrogen. The main challenges utilizing its extremely low temperature ortho- para-hydrogen conversion. These two have led urgent development liquefaction, storage, transportation. In addition, handling must updated regularly, especially facilitate massive large-scale

Potential Liquid-Organic Hydrogen Carrier (LOHC) Systems: A Review on Recent Progress

Energies, Journal Year: 2020, Volume and Issue: 13(22), P. 6040 - 6040

Published: Nov. 19, 2020

The depletion of fossil fuels and rising global warming challenges encourage to find safe viable energy storage delivery technologies. Hydrogen is a clean, efficient carrier in various mobile fuel-cell applications owned no adverse effects on the environment human health. However, hydrogen considered bottleneck problem for progress economy. Liquid-organic carriers (LOHCs) are organic substances liquid or semi-solid states that store by catalytic hydrogenation dehydrogenation processes over multiple cycles may support future Remarkably, LOHC systems has attracted dramatically more attention than conventional systems, such as high-pressure compression, liquefaction, absorption/adsorption techniques. Potential media must provide fully reversible via processes, thermal stability, low melting points, favorable thermodynamics kinetics, large-scale availability, compatibility with current fuel infrastructure practically employ these molecules applications. In this review, we present considerable aspects development ideal systems. We highlight recent candidates their approach, well briefly discuss theoretical insights understanding reaction mechanism.

Hydrogen liquefaction and storage: Recent progress and perspectives

Renewable and Sustainable Energy Reviews, Journal Year: 2023, Volume and Issue: 176, P. 113204 - 113204

Published: Feb. 16, 2023

The global energy sector accounts for ∼75% of total greenhouse gas (GHG) emissions. Low-carbon carriers, such as hydrogen, are seen necessary to enable an transition away from the current fossil-derived paradigm. Thus, hydrogen economy concept is a key part decarbonizing system. Hydrogen storage and transport two elements economy. can be stored in various forms, including its gaseous, liquid, solid states, well derived chemical molecules. Among these, liquid due high density, ambient pressure, purity (no contamination risks), mature technology (stationary storage), suitable large-volumes over long distances has gained increased attention recent years. However, there critical obstacles development systems, namely intensive liquefaction process (∼13.8 kWh/kgLH2) boil-off losses (liquid evaporation during storage, 1–5% per day). This review focuses on state related supply chain. liquefaction, cryogenic technologies, transmission methods regasification processes discussed terms industrial applications underlying technologies understand drivers barriers become commercially viable emerging A finding this technical that play important role - technological innovations achieved parallel demonstrations market efforts by countries committed their strategies.
