Special Issue "Hydrogen Production and Utilization"
Deadline for manuscript submissions: 31 July 2018
Hydrogen is a secondary energy source (energy carrier), which is believed very important in global energy systems. Although it is currently mainly produced from fossil fuels, including natural gas, coal, and oil, the increasing share of renewable energy, such as biomass, wind and PV, is also believed to increase the share of hydrogen utilization in our energy system. Therefore, effective, clean and efficient hydrogen production, storage, transportation, and utilization are urgently demanded.
This Special Issue focuses on both hydrogen production and utilization, including its storage and transportation. The following topics are welcomed, but the Special Issue is not limited to them.
- Hydrogen production and utilization system
- Conversion processes, such as gasification, shift reaction, chemical looping, etc.
- Liquid organic hydrogen carrier
- Hydrogen to ammonia
- Ammonia utilization, especially for energy harvesting
- Metal hydrides
- Hydrogen liquefaction
- Hydrogenation and dehydrogenation
- Hydrogen transportation
- Efficient hydrogen-based power generation, such as Graz cycle, fuel cell, etc.
- Catalyst for hydrogen production, storage and utilization.
- Economic analysis on hydrogen production, storage, transportation, and utilization
- Environmental assessment
- Integrated system
Accordingly, this Special Issue is open for the following types of manuscripts covering the whole breadth of sustainable urban and rural development issues and concerns:
- Original research articles;
- review articles;
- technical report;

Title: Integrated vehicular refueling stations for liquefied and compressed natural gas and hydrogen
Authors: John A. Barclay and Jamie D. Holladay
Abstract: Decarbonization of fuels for global transportation is an objective recognized as an important megatrend. To strive toward this objective, renewable methane and hydrogen are obvious fuels. The energy supply chain for these gaseous fuels to economically satisfy large numbers of widely dispersed end-users requires distributed production, storage, transport, delivery, and dispensing techniques for liquid and compressed methane (natural gas) and liquid and compressed hydrogen. Such interlinked infrastructure is much more challenging to establish than that for large-scale, centralized, larger end-users in non-transportation sectors. In addition to installation of thousands of distributed small-scale, inexpensive, and refueling stations reliably and safely supplying LNG, CNG, LH2, and CH2, these fuels must be delivered at prices attractively lower than prices of gasoline or diesel per equivalent gallon or cost/mile driven. Successfully overcoming these barriers requires breakthroughs in the capital cost and efficiency of small-scale liquefaction of methane and hydrogen, while substantially reducing cost of refueling infrastructure. The technical approach described in this paper will illustrate one such technique. We quantitively show how compression of locally produced LNG and stored at ~0.24 MPa and ~123 K can be used to make CNG for vehicle fuel at ~31 MPa and ~290 K. Simultaneously, the latent and sensible heats from warming cold LCNG can be used to pre-cool hydrogen process gas from ~290 K to ~140 K before its liquefaction. This synergistic pre-cooling reduces hydrogen’s room-temperature specific liquefaction energy by up to 64%. A highly-efficient, single-stage active magnetic regenerative liquefier operating from ~140 K to ~20 K can efficiently make LH2¬. The density of LH2 is large enough to be converted at CH22 at ~ 875 bar through a recuperative thermal compressor as it warms to ~250 K for dispensing at 700 bar without use of a multi-stage hydrogen gas compressor.
