Mazda Postpones H2 Car Because of Poor Existing Storage


As a continuation of the previous hydrogen storage article, we now found out another important player in the auto industry that wants to use hydrogen in another form, and can’t do it efficiently because of lack of storage: Mazda.

They don’t want to use hydrogen in a fuel cell device, but rather burn it and use the power. The principle is the same with the one in BMW 7-series from last year, but they have something different on hand. Mazda doesn’t use the classic piston-engine, which can backfire sometimes if fueled with hydrogen. Instead, they use a Wankel rotary engine.

According to Wikipedia: “The Wankel engine is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. Its four-stroke cycle is generally generated in a space between the inside of an oval-like epitrochoid-shaped housing and a roughly triangular rotor. This design delivers smooth high-rpm power from a compact, lightweight engine“.

Mazda has been running over 30 H2-powered cars for several years, and had some success with them. It’s interesting seeing several hydrogen-powered motors emerging on the market, and it’s more interesting to see which is more efficient. I still believe in electric cars, rather than the stoge-age-old combustion…

Anyway, they will postpone their plans with this car until a safe method for storing the hydrogen is discovered. The plans are that in at least 5 years we won’t see any of this H2 cars on the streets.
