“…The share of biomass in the production of biohydrogen is also expected. Xiangyu Meng et al [69] predict that the potential of biomass for energy production in China is 2952 × 10 4 kW. However, the role of biomass in the production of biohydrogen in this solution concerns only the function of the fuel to produce electricity, which would then be used to produce biohydrogen.…”

Biohydrogen production is a promising alternative to replace fossil fuels in an environmentally friendly way. In addition to the many available renewable energy sources, the production of “colored” hydrogen and biohydrogen occupies an irreplaceable position due to the undeniable availability of biomass and the need to manage food waste (FW). This article presents the current state of biohydrogen production technology—examples on continents (America, Africa, Asia, Australia and Oceania) and in Europe in terms of the efficiency of dark methane fermentation (CH4). Biophotolysis processes leading to the production of biohydrogen are indicated: directly and indirectly. The mechanism of the fermentation process of obtaining hydrogen and two-stage hydrogen fermentation are presented. The novelty of this article is the development of innovative trends in the development of the biohydrogen industry in Europe. Various models of the biohydrogen process are presented for different raw materials and proportions of substrates used in co-fermenters. Researchers from China are the undisputed pioneers in the use of renewable energy sources. However, improved energy self-sufficiency and environmental impacts are reflected in the growing number of pilot installations operating in European countries. This also gives hope for rapid progress towards full animal and FW management also in Poland.

“…The high working temperature leads to higher efficiency than AWE and PEM technology, and the highest efficiency can be close to 100% [81]. Hydrogen is generated by water electrolysis under high temperature [82,83]. In the solid oxide electrolyzer, water is converted into water vapor at high temperature, and the current electrolyzes the water molecules adsorbed on the cathode catalytic layer into H + and O 2-;the free electrons of H + transmitted through the external circuit are reduced to H2, and O 2-passes through the solid electrolyte layer to reach the anode catalytic layer.…”

“…As the PCC technology, its working temperature is higher, and the catalyst used is high-temperature ceramic material. The anode is composed of perovskite or perovskite ceramic composite, and the cathode is made of nickel-based ceramic composite material, so a precious metal catalyst is not needed, and the preparation cost of the catalyst is low [ 83 ]. Additionally, SOE technology can also be used for the electrolytic reduction of CO 2 to realize CO 2 conversion and emission reduction [ 82 ].…”

“…Among them, "transportation" connects the upstream hydrogen energy production, storage, and downstream hydrogen energy utilization, which is an important link in the development of the hydrogen energy industry [3]. According to the current technological level, the cost of hydrogen energy storage and transportation accounts for over 30% of the final hydrogen consumption cost [2,4]. Mixing hydrogen into natural gas and utilizing existing natural gas pipelines for transportation is an important way to achieve large-scale and efficient hydrogen transportation [5,6].…”

As a zero-emission green clean energy, hydrogen energy is an important means to achieve the strategic goal of carbon neutrality and an important part of the energy Internet. Hydrogen-doped natural gas transportation is an economical and feasible scheme to realize long-distance transportation of hydrogen by using the existing natural gas pipeline network. However, the addition of hydrogen to natural gas will cause obvious changes in the physical properties of the transport medium, which will have a certain impact on the transport characteristics and flow measurement of the pipeline. The main problem is that we need to understand the changes of physical properties after natural gas mixed with hydrogen to ensure the safe operation of natural gas pipe network mixed with hydrogen. Based on this situation, this paper takes BWRS equation as the theoretical basis, selects typical natural gas temperament, calculates and solves the physical parameters of natural gas under different hydrogen blending ratios, and compares them with the standard physical reference values. After verification, the results are used to explore the physical properties of hydrogen-doped natural gas with hydrogen blending ratio, temperature and pressure as variables. The relative average absolute value error (RAAD) of the calculated physical properties of hydrogen-doped natural gas in this paper is less than 2% compared with the reference value of standard physical properties, which can provide theoretical data basis for studying hydrogen-doped pipeline transportation, ensuring pipeline transportation safety and hydrogen-doped natural gas metering.
