The Hopewell Project is a solar-powered residence in North America that generates hydrogen for subsequent reconversion into electricity, meeting all of the home's power needs, including heating and cooling, through renewable solar energy.
The solar/hydrogen-powered home is located northwest of Hopewell, New Jersey in East Amwell Township, cost $500,000 and was dedicated on October 20, 2006.
The project also got equipment and expertise from a number of commercial sponsors including Exide, which donated some $50,000 worth of batteries, and Swagelok, an Ohio company that provided stainless steel piping costing around $28,000.
The excess is stored in the form of hydrogen which is used in the winter—when the solar panels can't meet all the domestic demand—to make electricity in the fuel cell.
The Hopewell Project is currently developing a complete solar-hydrogen-fuel cell turnkey system that could be installed on an average home.
