“…By 2030, the International Renewable Energy Agency emphasizes that renewable energy sources can make hydrogen production cost-competitive with fossil fuels. This is due to decreasing costs, economies of scale, and improved performance [37,38]. In 2022, the global production of lowemission hydrogen constituted less than 1% of the entire global hydrogen output.…”

Hydrogen constitutes an integral component within an expansive array of energy technologies poised to facilitate the nation's transition towards achieving a net-zero state. In additional, this endeavor involves harnessing regional resources judiciously, thereby fostering equitable and sustainable growth. The strategic development and utilization of hydrogen technologies necessitate a nuanced approach, encompassing an assessment of diverse technologies spanning various sectors especially power sector. Such a meticulous strategy aims to forge the most efficacious, cost-effective, and sustainable pathways, underpinned by the discerning adoption of these technologies in the market. The article delves into the intricate relationship between hydrogen and fuel cell technologies, shedding light on their combined impact on the evolving landscape of electricity generation. A particular focus is placed on the integration of variable renewable energy sources, elucidating how hydrogen serves as a key enabler in optimizing the utilization of these fluctuating energy resources. In addition, the article encompasses various methods of hydrogen production, exploring their technological advancements and implications for achieving sustainable electricity generation. Emphasizing the significance of technology development in the hydrogen sector, the paper delves into the potential of hydrogen production methods and their implications for advancing sustainable electricity generation. In essence, the article navigates the trajectory of the hydrogen sector's evolution within the broader context of electricity generation, offering valuable insights into the ongoing developments, challenges, and opportunities. By addressing the critical nexus between hydrogen technologies and the dynamic electricity landscape, the paper aims to contribute to the discourse on the future trajectory of investments in the hydrogen sector for enhanced electricity generation. To Conclude, the United Kingdom has committed GBP 20 billion over a span of 20 years to the development of Carbon Capture, Utilization, and Storage (CCUS) facilities. Additionally, the nation has identified and shortlisted electrolysis projects totalling 408 megawatts (MW) capacity. In Korea, Hanwha Impact has achieved a significant milestone by attaining a 60% hydrogen co-firing share in an 80 MW gas turbine, representing the largest co-firing share recorded thus far in mid-to-large gas turbines. Meanwhile, Anhui Province Energy Group in China has successfully conducted trials involving the co-firing of ammonia at a 300 MW unit. The Group has plans to further extend these trials, aiming to achieve a 50% co-firing level at a 1 GW coal unit. In the United States, notable progress has been made, with a 38% hydrogen co-firing share attained in 2023 at an operational 753 MW combined-cycle power plant.

The emerging green hydrogen value chain provides an opportunity to develop joint sustainable strategies between different countries and implement measures to mitigate potential adverse effects. We analyze whether the green hydrogen value chain can aid in meeting the objectives outlined in the 2030 Agenda. The Value Chain Assessment methodology that we developed enables the identification of direct and indirect influences, and the categorization of positive and negative effects, of each segment (production, transportation, and end-use) of the green hydrogen value chain on the 17 SDGs and their 169 targets. We also analyze the associated temporal dimensions and reciprocal interdependences, to clarify the dynamics of the value chain over time and across different geographical scales. We present a strategic framework that can help in fostering the green hydrogen value chain for the implementation of sustainable development. We find that the use of green hydrogen can clearly accelerate progress on the SDGs in the short-term, but adverse effects could arise in the medium- to long-term. The realization of the green hydrogen value chain requires synchronized investments and policies across space and time.
