Regenerative braking is built into all electric vehicles and is a feature that helps you maximise range, and makes the process of braking less wasteful. In comparison – a combustion engine car’s brakes convert kinetic energy into wasted heat to slow the vehicle.

The goal of University of Delaware project is to develop new low cost hydrogen storage substrates from an abundant waste material (6 billion lbs/yr in US): chicken feathers. By comparison, making a 20-gallon hydrogen fuel tank that uses carbon nanotubes could cost $5.5 He says his team is working to improve that range.

So when you open the exhaust valve to dump expanded gas out to the environment, you lose all of that energy stored in the high-pressure exhaust gases and you create a lot of noise. Slowly decompressing the gases would waste less of that energy and make for a much quieter engine. —Timothy Shedd. —Tim Shedd.

Several companies are developing chemical processes, but these are still at pilot scale, and Aqua’s execs see serious challenges in delivering the required product purity and dealing with waste streams. There are real challenges with waste streams—they yield a lot of sulfuric acid and sodium sulfate, which will need to get landfilled.

In the last two decades of the 20th century, we identified thousands of toxic waste dumps and worked to ensure that people were not in the pathways of exposure to poison. That is the only comparison that matters. That ended in 1984 when the North River sewage treatment plant opened. Moreover, as technology develops, it will improve.

More significantly it must be realized that hydrogen, just like a battery, is not an energy source in itself, but simply a means of storing energy. The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy. So why haven’t FCEV becoming as prolific as other electric cars?
