PTE Summarization Written Text Exercise 14
Hydrogen Energy as a Fuel Source
Hydrogen is gaining attention as a clean and versatile fuel that could play a major role in decarbonizing the energy sector. When used in fuel cells, hydrogen produces electricity with water as the only byproduct, making it an attractive alternative to fossil fuels. It can also be stored and transported, offering advantages over intermittent energy sources like solar and wind. However, most hydrogen today is produced from natural gas in a process that emits carbon dioxide, raising concerns about its environmental impact. Researchers are exploring "green hydrogen" made from electrolysis powered by renewable energy, though this method is currently expensive. Governments and private companies are increasing investment in hydrogen infrastructure, aiming to make it a practical solution for industries like transport, manufacturing, and heating. The future of hydrogen will depend on how effectively technological and economic challenges are addressed.
