2004 | Home Energy Station (2nd generation)

Honda began operating the second generation of its Home Energy Station (HES II) in November 2004.

The HES II incorporates several subsystems which utilize Plug Power's proprietary technology. By optimizing production and storage of hydrogen for home use, the space needed for natural gas reformation and hydrogen compression is significantly reduced.  Previously housed in two separate units, it is internalized into one, significantly smaller package that includes the natural gas reformer, hydrogen purifier, fuel cell stack, compressor, fuel storage and delivery system. This fully integrated system provides improvements in overall operation and efficiency.
