“…The Joule–Thomson effect refers to the temperature change when a gas expands from high to low pressure during an isenthalpic process with no external work. However, during the hydrogen charging process, hydrogen has a negative Joule–Thomson coefficient, resulting in an increase in temperature as the pressure decreases . Unlike ordinary gaseous molecules (the compressibility factor, Z , < 1), the small size of hydrogen molecules leads to a repulsive effect between molecules during expansion ( Z > 1), thus resulting in a temperature rise.…”

The growing demand for hydrogen fuel cell vehicles requires an energy-efficient and sustainable hydrogen refueling infrastructure. However, conventional gaseous hydrogen refueling stations have limitations in improving energy efficiency and sustainability because they consume a significant amount of electricity during hydrogen compression and cooling processes. Herein, we propose a sustainable design for hydrogen refueling stations that utilizes the cold energy of liquid hydrogen to improve energy efficiency and reduce the life-cycle environmental impact. The process design involves utilizing the cold energy of liquid hydrogen for hydrogen cooling through a heat exchanger and electricity generation through an organic Rankine cycle. Furthermore, the developed process design substantially reduces energy consumption in the hydrogen compression process by using a liquid hydrogen pump instead of a low-pressure (LP) compressor. Energy efficiency analysis and life-cycle assessment were performed to verify that the new design is preferable to the conventional gaseous hydrogen refueling station. Consequently, this study demonstrates the potential of the developed liquid hydrogen refueling system to enhance the sustainability of future hydrogen refueling infrastructures.

“…During compression, hydrogen undergoes a cooling effect, which raises concerns regarding the potential for pressure vessel materials to be damaged if the temperature drops too low. Conversely, when hydrogen is relaxed, it undergoes a warming effect [11]. Figure 1 shows the layout of an on-site hydrogen generation system.…”

Decarbonizing high temperature heat in industrial processes is challenging as there are only few alternative fuels to reach the necessary temperatures. In steel mills the material must be heated up to 1250 °C before hot rolling of steel. Currently, this energy-intensive step is done in steel reheating furnaces fueled with natural gas. Synthetic fuels such as green hydrogen, synthetic methane and green ammonia are possible alternatives for substituting the current polluting energy carrier and in many future climate strategies considered as a crucial component for achieving greenhouse gas neutrality. In this paper, we present options for on-site production of synthetic fuels for steel mills and discuss them by a qualitative approach. Specifically, we investigate hydrogen, synthetic methane and ammonia. We consider state of the art technologies and apply them to a real-world use case from the steel processing industry in Austria. We point out the benefits of on-site generation of synthetic fuels as opposed to external supply in the case of steel mills. Depending on technology, we discuss possibilities for heat integration, implementation of carbon dioxide looping and efficiencies of the systems. We highlight the significant increase in the demand for electrical energy. Further, we discuss challenges of combustion in relation to nitrogen emissions, combustion behavior and effects on steel quality. Our results show hydrogen to be advantageous in many aspects when considering a fuel switch in steel mills with on-site generation. But also we identify synthetic methane as an interesting option that should be further examined.

As a subdivision of the hydrogen energy application field, ship-borne hydrogen fuel cell systems have certain differences from vehicle or other application scenarios in terms of their structural type, safety, environmental adaptability, and test verification. The connection method of the ship-borne hydrogen storage cylinder (SHSC) is very important for the hydrogen fuel cell ship, and the structural parameters of the SHSC are particularly important in the hydrogen refueling process. To ensure the safe and reliable operation of the hydrogen-powered ship, research on the filling of the SHSC under different connection modes was carried out during refueling. In our study, a thermal flow physical model of the SHSC was established to research the hydrogen refueling process of the series and parallel SHSCs. The influence of series and parallel modes of the SHSCs on the hydrogen refueling process was explored, and the evolution law of the internal flow field, pressure, and temperature of series and parallel SHSCs under different filling parameters was analyzed by numerical simulation. Our results confirmed the superiority of the parallel modular approach in terms of thermal safety during refueling. The results can supply a technical basis for the future development of hydrogen refueling stations and ship-board hydrogenation control algorithms.
