A comprehensive energy flow analysis method based on hydrogen energy to electric energy conversion

Abstract

Abstract With increasing global concerns about climate change, more and more countries and regions are turning to sustainable energy, and hydrogen energy, as one of the representatives of clean energy, is gradually becoming one of the key areas for development in various countries. Due to its high energy density, easy storage, and pollution-free characteristics, hydrogen energy has been widely used in fields such as automobiles, aviation, and petrochemicals. In the automotive industry, hydrogen energy, as a renewable and clean energy source, has become one of the development directions. Compared to traditional fuel, hydrogen-powered vehicles not only achieve zero emissions but also have higher energy efficiency and can achieve longer range. Currently, multiple countries around the world are accelerating the promotion of hydrogen-powered vehicles and building related infrastructure such as hydrogen refueling stations. In the aviation field, hydrogen energy also has broad application prospects. Traditional aviation fuel contains a lot of hydrocarbons, so the pollution problem of the aviation industry has been a concern. As a clean and renewable energy source, hydrogen energy not only solves the pollution problem in the aviation industry but also has a very high energy density, providing sufficient power to support aircraft flight. In addition to the automotive and aviation fields, hydrogen energy can also be widely used in the petrochemical industry. Currently, traditional petrochemical production processes emit many harmful substances such as carbon dioxide, greatly affecting environmental quality. By using hydrogen energy, harmful substances such as carbon dioxide generated in traditional petrochemical processes can be converted into renewable resources, thus achieving an environmentally friendly, efficient, and sustainable production model.
