Special Issue Information

Dear Colleagues,

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;

Solid oxide fuel cells (SOFCs) are promising electrochemical devices which translate chemical energy directly into electric energy with high efficiency and low pollution. However, the control of the output voltage of SOFCs is quite challenging because of the strong nonlinearity, limited fuel flow, and rapid variation of the load disturbance. Nowadays, proportional-integral-derivative (PID) controllers are commonly utilized in industrial control systems for their high reliability and simplicity. However, it will lead to overshoot and windup issues when used in the wide-range operation of SOFCs. This paper aims to improve the PID controller performance based on fuzzy logic by (1) identifying a linear model based on the least squares method; (2) optimizing the PID parameters based on the generated linear model; and (3) designing a fuzzy adaptive PID controller based on the optimized parameters. The simulation results of the conventional PID controller and the fuzzy adaptive PID controller are compared, demonstrating that the proposed controller can achieve satisfactory control performance for SOFCs in terms of anti-windup, overshoot reduction, and tracking acceleration. The main contribution of this paper can be summarized as: (1) this paper identifies the SOFC model and uses the identified model as a control object to optimize conventional PID controllers; (2) this paper combines a fuzzy logic control scheme and PID control scheme to design our proposed fuzzy adaptive PID controller; and (3) this paper develops an anti-windup structure based on a back-calculation method to reduce saturation time and overshoot.

As environmental awareness among the public gradually improves, it is predicted that the trend of green consumption will make green products enter the mainstream market. Hydrogen-electric motorcycles, with eco-friendly and energy-efficient characteristics, have great advantages for development. However, as a type of innovative product, hydrogen-electric motorcycles require further examination with regard to consumer acceptance and external variables of the products. In this study, consumer behavioral intention (BI) for the use of hydrogen-electric motorcycles and its influencing factors are discussed, using innovation resistance as the basis and environmental concern as the adjusting variable. Consumers’ willingness-to-pay (WTP) for hydrogen-electric motorcycles is estimated using the contingent valuation method (CVM). The results found that (1) perception barriers, viz., usage barrier, value barrier, risk barrier, tradition barrier, and price barrier are statistically significant, whereas image barrier is not; (2) a high degree of environmental concern will reduce the consumers’ innovation resistance to the hydrogen-electric motorcycles; (3) up to 94.79% of the respondents of the designed questionnaire suggested that the promotion of hydrogen-electric motorcycles requires a subsidy of 21.9% of the total price from the government. The mean WTP of consumers for the purchase of hydrogen-electric motorcycles is 10–15% higher than that of traditional motorcycles. Full article

Hydrogen mobility is one option for reducing local emissions, avoiding greenhouse gas (GHG) emissions, and moving away from a mainly oil-based transport system towards a diversification of energy sources. As hydrogen production can be based on a broad variety of technologies already existing or under development, a comprehensive assessment of the different supply chains is necessary regarding not only costs but also diverse environmental impacts. Therefore, in this paper, a broad variety of hydrogen production technologies using different energy sources, renewable and fossil, are exemplarily assessed with the help of a Life Cycle Assessment and a cost assessment for Germany. As environmental impacts, along with the impact category Climate change, five more advanced impact categories are assessed. The results show that from an environmental point of view, PEM and alkaline electrolysis are characterized by the lowest results in five out of six impact categories. Supply chains using fossil fuels, in contrast, have the lowest supply costs; this is true, e.g., for steam methane reforming. Solar powered hydrogen production shows low impacts during hydrogen production but high impacts for transport and distribution to Germany. There is no single supply chain that is the most promising for every aspect assessed here. Either costs have to be lowered further or supply chains with selected environmental impacts have to be modified. Full article

Solid oxide fuel cell (SOFC) is widely considered as an alternative solution among the family of the sustainable distributed generation. Its load flexibility enables it adjusting the power output to meet the requirements from power grid balance. Although promising, its control is challenging when faced with load changes, during which the output voltage is required to be maintained as constant and fuel utilization rate kept within a safe range. Moreover, it makes the control even more intractable because of the multivariable coupling and strong nonlinearity within the wide-range operating conditions. To this end, this paper developed a multiple model predictive control strategy for reliable SOFC operation. The resistance load is regarded as a measurable disturbance, which is an input to the model predictive control as feedforward compensation. The coupling is accommodated by the receding horizon optimization. The nonlinearity is mitigated by the multiple linear models, the weighted sum of which serves as the final control execution. The merits of the proposed control structure are demonstrated by the simulation results. Full article

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.
