Hydrogen production from renewable sources: Bridging the gap to sustainable energy and economic viability

Hydrogen energy presents a fascinating possibility for reaching the goal of zero-carbon energy use in urban areas. The correlation between urban regions' electricity usage and the trends of hydrogen energy production is quantitatively examined in this research. It examines hydrogen energy development, green hydrogen generation, and energy consumption globally. This study uses a panel vector autoregressive (PVAR) method and a coupling coordination degree (CCD) method to investigate the dynamic relations between renewable energy transition and urban hydrogen energy utilization. A hypothetical assessment of green hydrogen generation by 2030 is also included in the report, which is in accordance with Chinese government initiatives. It suggests a consumption plan that incorporates both economic growth and sustainable development. The main findings are as follows: (1) the areas with the highest potential for environmentally friendly hydrogen generation are not always the same ones wherein hydrogen energy continues to be developed. There is a stronger correlation between the integrated growth of hydrogen and renewable energy in cities with greater energy usage. (2) The progress in hydrogen energy speeds up the move to using green energy in cities much more than the increase in utilization capacity alone. (3) Developing renewable hydrogen initiatives in regions with high production capacity is crucial, as hydrogen output is substantially higher in the optimistic Scenario compared to the Pessimistic Scenario.
