Recent research conducted by Stanford University proposes a transformative approach to global energy systems, indicating that the integration of hydrogen and battery storage could significantly facilitate the transition to clean energy. A report published in the open-access journal iScience assesses the feasibility and economic consequences of transitioning 145 countries to electrical grids based 100% on renewable energy sources.
Rather than quoting, it can be described that the research has shown that electrification across all energy sectors plays a crucial role as the first step in achieving the goal, bringing about a 38% reduction in energy demand through greater electrical efficiency compared to combustion processes. The second stage, highlighted by the report’s author, involves providing energy solely from renewable sources like wind, water, and solar power, with the use of storage. This strategy not only eliminates the need for fossil fuel extraction and refinement but also contributes to an 11.3% reduction in global energy consumption.
The study predicts a significant 61% decrease in annual energy costs for countries adopting clean energy solutions. Mark Z. Jacobson, the report’s author and a professor at Stanford University, expressed to pv magazine USA that the results unequivocally demonstrate to countries that 100% clean and renewable energy grids not only lower costs but are equally as reliable as the current energy system.
The research utilizes an advanced computer model to analyze different scenarios and emphasizes the role of hydropower, batteries, and green hydrogen in ensuring grid reliability. While hydrogen storage offers benefits in certain regions by absorbing excess electricity from renewable sources, it also comes with challenges such as initial costs. However, Jacobson emphasized the significant financial advantages of this technology and suggested that policymakers prioritize investments in battery storage and green hydrogen, rather than alternative approaches like carbon capture and non-hydrogen electrofuels.
