Some of the key markets for fuel cells may surprise you - combined heat and power (CHP) for residential applications and remote sensing to monitor dams, wildlife and weather stations.
The CHP market is growing at a compound annual rate of 67.7% according to Pike Research, and predicts the remote sensing market will be the "break out" market for the technology.
In 2012, the fuel cell and hydrogen industry will produce $785 million in revenue worldwide, crossing the three quarter million threshold for the first time, says Pike.
What most expected to be a strong market for fuel cells - portable consumer electronics applications - isn't yet showing much promise, they say. Many of the pioneering fuel cell companies - most of whom are shadows of what they once were - were developing them for cell phones and computers.
