“…In addition, conventional statistical methods can produce inaccurate results when heteroscedasticity and CD are present in the data (Khan et al 2021). Due to the restrictions imposed by these analyses, we evaluated the panel's cointegration using Westerlund and Edgerton (2008), who were able to take into account the CD, structural breaks, and autocorrelation. Here are the numbers that were used by Westerlund and Edgerton (2007):…”

The problem for developed and developing economies is achieving sustainable development and cleaner production. Income, institutional regulations, institutional quality, and international trade are the primary factors of environmental externalities. This research looks at 29 provinces in China between 2000 and 2020 to determine the effect of green finance, environmental regulations, income, urbanization, and waste management on renewable energy generation. Similarly, the current study uses the CUP-FM and CUP-BC for the empirical estimation. More precisely, the study shows the positive influences of environmental taxes, green finance index, income, urbanization, and waste management in renewable energy investment. However, the different measures of green finance, such as financial depth, financial stability, and financial efficiency, also positively contribute to renewable energy investment. Therefore, it can be considered the best solution to environmental sustainability. However, imperative policy implications are given to attain the peak of renewable energy investment.

“…The SGCC has unequivocal advantages in its ultrahigh-voltage transmission technology [50], and this could benefit the construction of hydrogen pipelines to some extent. At first glance, this strength does not directly contribute to the hydrogen economy due to the competitive relationship between hydrogen pipelines and HVDC lines, as they can both deliver energy, in different forms, to end customers [36]. However, the acknowledgment of such a relationship can yield more precise judgments on the development of hydrogen pipelines, as well as potential synergy.…”

“…Within the EaaS model, the capital-intensive nature of constructing hydrogen transmission networks may place any participants in a less competitive position than other well-funded competitors (T3), but the SGCC could stand out by utilizing its knowledge of electricity transmission lines (S1) and experience in managing capital-intensive projects (S5) to optimize the planning of new hydrogen pipelines. Hydrogen pipelines and electricity transmission infrastructure could overlap in the functions of meeting certain types of end customers' energy needs [36,37]; without careful planning, unwanted waste may be caused. To enable more optimal planning for both electricity transmission lines and hydrogen pipelines, the SGCC may consider partnerships with pipeline companies such as PipeChina, another large, state-owned enterprise focusing on the transmission of oil and natural gas in various forms.…”

“…A levelized cost analysis by Patel et al delivered a similar conclusion, in that hydrogen pipelines could become more competitive than HVDC in 2050 at transmission distances of more than 350 km [35]. Wu et al optimized the transmission capacities of hydrogen pipelines, natural gas pipelines, and high-voltage transmission lines in China to determine the lowest system transmission cost [36]. Zwaan et al depicted scenarios in which Europe imports both electricity and hydrogen from Africa via HVDC transmission lines and hydrogen pipelines in a collaborative manner [37].…”

The increasing penetration of renewable and distributed resources signals a global boom in energy transition, but traditional grid utilities have yet to share in much of the triumph at the current stage. Higher grid management costs, lower electricity prices, fewer customers, and other challenges have emerged along the path toward renewable energy, but many more opportunities await to be seized. Most importantly, there are insufficient studies on how grid utilities can thrive within the hydrogen economy. Through a case study on the State Grid Corporation of China, we identify the strengths, weaknesses, opportunities, and threats (SWOT) of grid utilities within the hydrogen economy. Based on these factors, we recommend that grids integrate hydrogen into the energy-as-a-service model and deliver it to industrial customers who are under decarbonization pressure. We also recommend that grid utilities fund a joint venture with pipeline companies to optimize electricity and hydrogen transmissions simultaneously.

“…Accelerating the development of hydrogen energy is an important strategic choice to cope with climate change, realize the zero-carbon goal, guarantee energy security, and promote the sustainable development of society. It is imperative to vigorously develop hydrogen production from renewable energy sources and orderly promote the development of the green and low-carbon hydrogen energy industry [8]. According to the China Hydrogen Energy Alliance Research Institute, driven by factors such as reducing carbon emissions, energy security, and promoting economic growth, 9 out of 20 countries accounting for 44% of the global GDP have formulated complete national hydrogen energy strategies, and 11 countries are in the process of formulating national hydrogen energy strategies [9,10].…”

Driven by the “dual carbon” goal and the construction of a New Power System, hydrogen energy as an electric energy storage medium will play an important role and be applied to each link of the power system in the future, showing the development trend as electric-hydrogen coupling. This paper researches 8 typical application scenarios of hydrogen energy throughout the source, grid, and load of a New Power System, describes their composition and characteristics, and calculates economic indicators using the life cycle method, such as the levelized cost of hydrogen (LCOH). At present, the LCOH is high, and the conditions for large-scale promotion have not been met in the short term. The LCOH shows a linear downward trend with the decrease of renewable energy levelized cost or electrolytic cell cost. The LCOH shows a first rapid and then slow downward trend as the efficiency and utilization hours of hydrogen production equipment increase. Generally, when the equipment efficiency exceeds 90% or the utilization hours exceed 19 hours, the improvement of relevant parameters has little impact on the LCOH. With the further improvement of key parameters, hydrogen production-based electricity will have a certain cost competitiveness in the future.
