What is Hydrogen Energy?
2 Answers
Hydrogen energy is a type of secondary energy. Below is relevant information about hydrogen energy: Introduction: Hydrogen energy is produced by utilizing other energy sources through certain methods. Under standard conditions, its density is 0.0899g/l. At -252.7°C, it can become a liquid. If the pressure is increased to hundreds of atmospheres, liquid hydrogen can transform into metallic hydrogen. Development Prospects: Hydrogen energy is regarded as the most promising clean energy source in the 21st century and is emerging as a low-carbon and zero-carbon energy solution. Hydrogen fuel cell technology has long been considered the ultimate solution for utilizing hydrogen energy to address future human energy crises.
Hydrogen energy, simply put, is a technology that uses hydrogen as an energy source. I often discuss this in automotive circles, especially hydrogen fuel cell vehicles like the Toyota Mirai. The working principle isn't complicated: hydrogen is obtained through electrolysis of water or other methods, stored in the vehicle, and then reacts with oxygen in a fuel cell to generate electricity, emitting only water without any exhaust pollution. This is particularly important for reducing carbon emissions, and many cities are now promoting it as a clean energy source for future vehicles. During testing, I found its advantages quite obvious, such as fast refueling—taking just a few minutes to fill up, unlike electric vehicles that require long charging times—and long driving ranges, making it suitable for long-distance travel. However, storage is a concern; hydrogen is flammable and must be safely stored in high-pressure tanks. Overall, hydrogen energy is a key player in the green revolution, but infrastructure like hydrogen refueling stations is still limited, and further technological improvements are needed to reduce costs. I believe that hydrogen and electric vehicles complement each other to form a complete solution.
