Just a short post to clear up a common mistake made by the media on the future of electric cars:
We do not have to choose between ‘electric’ versus ‘hydrogen’ cars. Hydrogen fuel cell vehicles are electric vehicles. The only alternative to the combustion engine is an electric motor. The question is – what should power that electric motor? Batteries or fuel cells? Why not both?
Good News: Electric vehicles are coming!
The good news is that stories on electric vehicles are popping up all over the web. Bloggers and mainstream media outlets are covering announcements for production volumes of electric vehicles that are coming from every corner of the world. Sooner or later a leader will step up a confirm our plans to kill the combustion engine-’.
Bad news: People confuse electric motors for energy storage devices
The bad news is that while trying to describe ‘the future’ most bloggers and journalist fall back on merely describing a snapshot view of today. Then they extrapolate it forward assuming the past will dictate the future. They see battery powered electric cars and assume this is the future.
Cars are not iPods, and batteries alone cannot carry the auto industry forward. While there is no doubt that the first generation of electric vehicles are going to be built around advanced lithium ion batteries, next generation electric vehicles (circa 2015-2025) are likely to integrate three different energy storage systems- batteries, hydrogen fuel cells and capacitors.
So while bloggers and journalists often describe uncertainty about the direction of the auto industry by asking: Is the future car powered by a battery or fuel cell? – the answer is both.
Hydrogen stored as a solid, then converted in a fuel cell produces electricity.
Hydrogen fuel cell cars are electric vehicles.
A ‘hydrogen economy’ is an economy driven by electricity. H2 is just the chemical storage system.
