Fuel cell powetrain are not the only way to use hydrogen to power a vehicle. A hybrid hydrogen powertrain could also work.

The Green Planet Group, Inc. recently tested its AAQIS, Inc. subsidiary’s On-Demand Hydrogen Generator.

AAQIS stands for Automotive Air Quality Improvement Systems.

AAQIS explained its technology utilizes the excess electricity generated by a vehicle’s engine to break down water into its base elements, hydrogen and oxygen. This gas is then fed into the engine resulting in improved mileage and reduced emissions.

The Green Planet Engineering Group said it had projected an improvement in fuel economy of approximately 11 percent and a reduction in emissions of up to 77 percent in gasoline and diesel fueled internal combustion engines.

In late September, the AAQIS On-Demand Hydrogen Generator was dynamometer tested at Klein Engines of Phoenix, Arizona. AAQIS explained its generator HHO (two parts hydrogen, one part oxygen) gas output was fed into the air intake on a Chevrolet Small Block V-8 350 cubic inch “crate” engine. Engine and generator performance was tested and recorded on an SF-902 dynamometer with test data collected through a Windyn computer interface software program. Operated by Robert King, of King Dyno, the system recorded accurate data spreadsheets and graphs, and monitored various temperatures, pressures and flows, keeping a close check on the engine performance, fuel consumption and emissions throughout each run.

“The test results reported by Robert King positively blew our entire team away! We recorded a fuel efficiency improvement of 40 percent and a reduction in exhaust emissions to very nearly zero,” said Green Planet Group CEO Ed Lonergan. “We knew our new design hydrogen gas generator would perform well, but the test results absolutely exceeded every expectation. Our engineering team was quite literally jumping for joy!”

To put this 40 percent in perspective, it is as if this V8 engine uses as little fuel as a small four cylinder engine while continuing to produce the same power.

The Green Planet Group engineering team added it will continue testing of the AAQIS On-Demand Hydrogen Generator later this month utilizing a Chevrolet V-8 Turbo Diesel 6.5 liter engine.

“Equally important and impressive was the Chevy engine performance,” said Tom Klein, founder of Klein Engines. “At Klein Engines, performance is our key measure of success. Engine performance with the AAQIS generator operating absolutely equaled the engine performance when run on pure gasoline. There was no performance degradation at all. In fact, the addition of the HHO gas to the combustion chamber very nearly completely burned all the hydrocarbons. This AAQIS hydrogen generator really is amazing. Top performance and a 40 percent improvement in mileage? That’s tough to beat!”

Positive results are now expected for the upcoming diesel engine test.

“We are eager to see these diesel engine test results,” added Lonergan. “Our hydrogen generator is designed to work on all engines, gasoline or diesel fueled. We anticipate diesel test results that will equal or exceed last month’s gasoline engine test results. We have already begun assembly of generator prototype production models. We know we’re onto something big here and expect to begin generator sales in early 2015.”
