The article discusses the historical evolution of human energy use, focusing on the transition from fuels with high carbon content to those with higher hydrogen content. This shift towards hydrogen has led to cleaner energy sources and a reduction in emissions over time. The transition from carbon to hydrogen, known as decarbonization, was interrupted around 1970 due to the stagnation of nuclear energy expansion. However, in recent years, the transition has resumed, driven by the increasing use of natural gas. The article emphasizes the importance of further increasing the utilization of hydrogen through technologies like nuclear power and advanced power plants to continue the trend towards cleaner fuels. The discussion highlights the role of various energy sources throughout history, from wood to coal, oil, and natural gas, each with differing hydrogen-to-carbon ratios. Moving towards hydrogen-based energy sources is seen as crucial for achieving a healthier world, promoting economic growth, and safeguarding the climate. The article also mentions the need for large near-zero emission power plants and nuclear power parks that can produce hydrogen for various applications, including industrial processes, fuel production, and energy storage. Overall, the sentiment of the article towards hydrogen is positive, emphasizing the benefits of transitioning to cleaner energy sources and the importance of further incorporating hydrogen technologies into the energy mix for a sustainable future.
