Hydrogen is currently being used for fuel in a number of different fields, including space rockets.
Because of the low impact that burning hydrogen has on the environment, many people are researching the possibility of using it as an alternative fuel in automobiles, and several companies have announced that they are currently in the preliminary processes of producing the first models.
At the 2012 World Hydrogen Energy Conference, four major manufacturers, including Honda, Daimler AG, Toyota, and Hyundai, all confirmed that they are exploring the possibilities and are aiming to release hydrogen-powered vehicles to the public some time in 2015. They may enter showrooms later in 2013.
This will mark a great achievement in alternative fuels. Hydrogen is extremely clean, but carries with it a myriad of obstacles to overcome.
The research needed to widely produce hydrogen powered cars has convinced some experts that it’ll take roughly 40 years, during which time it is likely that other, more accessible forms of energy will be implemented.
The amount of hydrogen needed to create reliable propulsion will necessitate high tank weights, high storage pressure, and the high capital cost of production.
While hydrogen is getting closer to being a solid alternative fuel, there are still a variety of hurdles to be jumped before it’s seen as a common option.
