A cheaper alternative

I drive 24 miles to work each day. I also drive home so that give me a minimum of 48 miles a day burning gasoline. On a good day if I am in my car, I get about 20 miles per gallon so it works out to a little over 2 gallons a day or about $10.00 a day to commute. I have been reading adds about using hydrogen for cars and would welcome it with open arms. It is part of water and so should be a lot cheaper than oil products that need to be imported from overseas.
