Phys.Org (Isle of Man, Oct. 30) -- Researchers from the civil engineering departments at Illinois and Penn State have discovered an effective method to convert waste heat into hydrogen gas without the use of fossil fuels. Roland Cusick, CEE assistant professor at Illinois, was part of the team that discovered a new method for making hydrogen gas that does not require the use of fossil fuels. In this method, the researchers are able to effectively produce hydrogen gas using energy stored in ammonium bicarbonate (a heat regenerable salt) and solar heat or waste heat (like that available at power plants).
