Two big Colorado energy groups have geared up to find a way to solve this. According to the Denver Post, Xcel Energy and the National Renewable Energy Laboratory have planned to use wind power to create hydrogen fuel, in a pilot program. Increasing the efficiency of wind generation by using it during off-peak hours, the team wants to produce hydrogen, and it would be stored, and used later to produce electricity when demands rises. It is the nation’s first attempt to merge two energy resources. Using a renewable resource, wind, to make the nonpolluting fuel, this technology takes clean energy to even greener levels.
