OIL! The scarce resource that is slowly dispersing from the face of our planet. Approximately 50-100 years from now, the availability of oil will become limited thus drilling the earth to harvest would be far to expensive and time consuming.
Undoubtedly, the insufficiency of oil is a major global issue and scientists are seeking the next best alternative fuel that will fuel tomorrow.

One of the big players of oil consumption are transportation vehicles. Acal Energy, A small British firm is looking to change this by using hydrogen as fuel instead of oil. The company is currently developing a special chemical to hydrogen that would enable cars drive it safely. This would not only be cheaper than oil but also more eco-friendly. However, would hydrogen powered cars be successful? We have seen that cheaper and eco-friendly does not always mean high in sales. Take a look at the all electric cars, barely anyone drives them. It would be interesting how to see how they can market hydrogen cars in order to make it a success.
