Mike Strizki’s utility bill is zero, thanks to some creative thinking using renewable energy technologies. By using solar panels, a hydrogen fuel cell, storage tanks and an electrolyzer, he has enough electricity even on the cloudiest days. And Strizki isn’t a hermit living in the dark off of snails and rainwater, either. His 3,500 square foot house is located in central New Jersey on 12 acres, with amenities you’d see in any 21st century home, like a hot tub and big screen TV. His renewable energy system even creates hydrogen he uses to power his fuel-cell car.

So how does he produce zero emissions?

On a sunny day, Strizki can get more than enough of his electricity from the solar panels. The excess goes to an electrolyzer that then breaks down a tank of water into oxygen and hydrogen. The oxygen is released into the atmosphere, but the hydrogen is stored in 10 1,000-gallon propane tanks. So when the solar panels aren’t producing enough energy, the hydrogen is piped to an air-conditioner-sized fuel cell that makes electricity.
The fuel-cell car in the garage is called “The New Jersey Genesis” and Strizki – a civil engineer – helped design the car and maintains it for the NJ Department of Transportation. He fills it up with the hydrogen made from his electrolyzer.

This sort of system isn’t going to be available commercially for the rest of us anytime soon. Strizki’s project is extremely expensive - $500,000, paid for in part with a $250,000 grant from the NJ Board of Public Utilities.

Strizki acknowledges that the enormous cost is a huge hurdle, but believes that, with mass production, the price of the system (not including solar panels) would be about $50,000 and the new solar system would be around $80,000 (some states like NJ offer rebates that cover up to 70 percent of the solar’s cost).

Then there’s the question of efficiency. Critics point out that electrolyzers are only 50 percent efficient. By the time the process is complete, the hydrogen that is converted back into electricity is only half of the energy with which the process started. Sending that power back to the grid, some say, would be more effective because it would displace other dirty energy sources.

Strizki has created a company called Renewable Energy International that engineers, installs, and supports renewable energy systems like his. Despite its costs and efficiency questions, he still believes that hydrogen is the best solution to our clean energy problems. “No one has said what I’m doing doesn’t work…Nothing is as wildly expensive as destroying the whole planet.”
