Hydrogen, the most abundant element in the universe, has the potential to become a zero-emission energy carrier for the future. However, hydrogen does not exist naturally; by unblocking the chemical bonds that form water and natural gas, two of many hydrogen-containing substances, hydrogen can be produced [1]. At 52,000 Btu/lb, hydrogen has the highest energy content per unit weight of all fuels [2]. This makes hydrogen an excellent energy carrier; an energy carrier moves and delivers energy in a usable form to consumers [1]. By combining hydrogen and oxygen, electricity can be produced, this is called a fuel cell [2]. As current energy sources are rapidly depleting and global warming is increasing, the development of a clean alternative energy source is imperative; Hydrogen fuel cell is a promising technology to serve as a source of both heat and electricity [3]. 200 years ago, William Nicholson and Anthony Carlisle wrote about the possibilities of creating electricity from hydrogen and oxygen [4]. 40 years later, William Grove built the first fuel cell [4]. The alkaline electrolyte fuel cell was the first fuel cell used; it was used in Royal Navy submarines and then again on the Apollo and Gemini space shuttles [4]. The hydrogen fuel cell produces electricity, heat and water [1]. The water produced is so clean that the astronauts on the Gemini space mission used it as drinking water [1]. Currently in the United States and Europe, compressed hydrogen is distributed for use in buses, trucks, forklifts and perhaps soon in racing cars [2, 5]. Between years of research, experience and the fact that fuel cells are already established around the world, what is the controversy? Why do so many people think hydrogen fuel cells are a bad...... middle of paper ... will be competitive with gasoline at $1.50/gallon [6]. Hydrogen is not as expensive as you think; The key to implementing a new system is to take small steps at a time. Think about the world we live in: it is full of dangers, but it also holds great potential. We have all learned to live and manage dangerous situations on a daily basis; we don't think twice about the high explosive gas we drive or the sharp knife we ​​use to cook dinner, the key is education. Same idea for hydrogen fuel cells, the engineers have done their job. They have developed safe and efficient processes to transport, store and distribute hydrogen gas; it is now our duty to embrace change and become informed users of hydrogen gas as we do with gasoline. By accepting the hydrogen fuel cell, we will slow global warming and create a bridge to a green future.
