“…We do so by evaluating different infrastructure options in terms of their political and economic feasibility. [6] Therefore, we apply a qualitative scenario approach and develop six macroeconomic scenarios [5] which we classify as sociotechnical scenarios [8]. The scenario development was based on brainstorming methods, interconnection, consistency analysis and cluster analysis and was accompanied by participatory feedback workshops.…”

“…Based on the current state of acceptance research on CCS, H2 technologies and pipeline infrastructure, a systematization of acceptance was elaborated. [6] To empirically examine social acceptance, explorative interviews with relevant stakeholders were conducted in a first step. The stakeholders are located at intersections between politics, economy/industry and society (N=10).…”

“…The ACT project 'ELEGANCY -enabling a low-carbon economy via hydrogen and carbon capture and storage (CCS)' extends the technical discussion by including economic, sociological and legal aspects. [6,7] In this paper, we show how to combine a macroeconomic and sociological approach by using the case study example of ELEGANCY on gas infrastructure modifications in Germany. We apply a qualitative macroeconomic scenario analysis and a sociological acceptance analysis to get aggregate insights for the transition towards a lowcarbon economy.…”

“…For example, the European Union has launched a hydrogen strategy, with investments amounting to 400 billion euros, until 2030. In addition to Germany's approval of the National Hydrogen Strategy, with investments amounting to 9 billion euros [31]. The same thing in France, which has allocated 7 billion euros for the production of green hydrogen.…”

Hydrogen is the most abundant gas in the universe and is classified by the World Energy Organization as the cleanest fuel in the world compared to other energy products. Therefore, the hope hangs upon it in achieving the zero fuel emissions strategy, which adopted by the largest countries in the world. Also, it is believed that by 2050, hydrogen consumption will represent 24 % of the global energy sector, with investments estimated at 2.5 trillion dollars, compared to only 139 billion dollars at present. There are three types of hydrogen (gray, blue and green) classified based on their production methods and carbon content. Gray hydrogen is usually produced by burning natural gas at high temperatures and once the carbon is removed or captured, the gray hydrogen turns into blue hydrogen. As for green hydrogen with zero emissions, it is produced through the electrolysis of water or by using renewable energy sources such as solar cell, wind energy, etc. to avoid any emissions during the production stages. Despite the efficiency of green hydrogen compared to other types, its price remains a major obstacle in the promotion and marketing, which is estimated at 3.5 Euro/kg, compared to 1.5 Euro/kg for blue hydrogen. In addition to some other obstacles related to infrastructure and raw materials used in the production stages. Recently, and in order to remove all these obstacles, the leading countries in the energy sector pumped more investments to study all these obstacles and assess the current hydrogen market, which in turn leads to the acceleration of the upscaling of hydrogen production. In this context, this research was developed to study all these current and future challenges. In addition to discussing the traditional and modern methods of its production. Besides taking a look at the projects under implementation in this regard.

“…The hydrogen embrittlement process in metal materials generally involves the following steps [10][11][12][13]: (1) hydrogen molecules are physically adsorbed on the material surface and chemically dissociate to produce hydrogen atoms; (2) atomic hydrogen diffuses into the interior of the material; (3) the diffused hydrogen atoms accumulate at defects or microcracks within the crystal structure of the specimen itself when the specimen is subjected to stress, reducing the bond strength between metal atoms because of the interaction between hydrogen and the metal atoms; (4) this then leads to the premature failure of the material. This idealized scenario is closely related to the expansion of hydrogen-assisted cracks in a high-purity hydrogen environment.…”

The use of hydrogen-blended natural gas presents an efficacious pathway toward the rapid, large-scale implementation of hydrogen energy, with pipeline transportation being the principal method of conveyance. However, pipeline materials are susceptible to hydrogen embrittlement in high-pressure hydrogen environments. Natural gas contains various impurity gases that can either exacerbate or mitigate sensitivity to hydrogen embrittlement. In this study, we analyzed the mechanisms through which multiple impurity gases could affect the hydrogen embrittlement behavior of pipeline steel. We examined the effects of O2 and CO2 on the hydrogen embrittlement behavior of L360 pipeline steel through a series of fatigue crack growth tests conducted in various environments. We analyzed the fracture surfaces and assessed the fracture mechanisms involved. We discovered that CO2 promoted the hydrogen embrittlement of the material, whereas O2 inhibited it. O2 mitigated the enhancing effect of CO2 when both gases were mixed with hydrogen. As the fatigue crack growth rate increased, the influence of impurity gases on the hydrogen embrittlement of the material diminished.
