This year, the U.S. Department of Energy showed its holiday spirit in traditional ways at its annual holiday party – with holiday cookies and punch at its downtown headquarters building. But, with a fun energy twist, Secretary Chu’s holiday tree was lit using a 150 W fuel cell instead of the local electric grid. The Trulite KH4 portable hydrogen fuel cell was able to combine hydrogen gas (from its HydroCell fuel cartridges) and oxygen from the air to produce electricity and heat. The other byproduct of this process – water – was recycled within the 23-lb unit.
Happy holidays!
