The article discusses the growing interest in using hydrogen as a fuel, especially in fuel cell technology. President Bush initiated a research program to explore hydrogen fuel and fuel cells as part of the country's energy policy. The aim is to reduce pollution, greenhouse gas emissions, and dependence on imported petroleum by producing hydrogen from domestic energy sources. Despite potential benefits, the current high costs of fuel cells and hydrogen fuel pose barriers to widespread adoption. Policy involvement raises concerns about research costs and government intervention in technology selection. The report addresses key questions about hydrogen fuel: what it is, how fuel cells work, potential applications, sources of hydrogen, transitioning to a hydrogen-based economy, and the role Congress can play in this transition.
