Analysis of several main hydrogen production technologies

Abstract

With economic development, social progress, and population growth, mankind's demand for energy increases. Fossil fuels such as coal, oil, and natural gas are accelerating consumption, and these fossil fuels are non-renewable, and their reserves are very limited. If we continue to use fossil fuels uncontrollably, it will inevitably cause acid rain and global warming. As a renewable energy source, hydrogen energy has the least environmental pollution, and hydrogen energy can be dispersed in large quantities and converted from renewable energy. At present, hydrogen production technology and cost are high. This article briefly explains the principles and advantages, and disadvantages of several hydrogen production technologies, etc., and the cost and work efficiency of various technologies. Studies have shown that biomass pyrolysis and photocatalytic hydrogen production have higher efficiency and lower cost, which can be used as future research directions. However, there are problems such as the unclear hydrogen production mechanism of biological pyrolysis and unstable solar energy. And its future research and development directions are discussed in more detail. The research on hydrogen production technology is to satisfy the requirements of national economic development and social development needs.
