Here’s the best part: the oxygen binds with aluminium and becomes aluminium oxide powder, which can be turned into new pucks indefinitely with the addition of more gallium. The resulting hydrogen gas is captured and sent immediately to the intake manifold to fuel the engine. The moment these pucks come into contact with water, a chemical reaction begins, and the water molecules are split into hydrogen and oxygen. Instead, it uses solid pucks of an alloy of aluminium and gallium to instantly create hydrogen whenever it’s needed. Image via IEEE SpectrumĪlGalCo’s hydrogen-on-tap (HOT) system has none of the bulky and dangerous trappings of other hydrogen vehicles. Pucks for Trucks Kurt Koehler and his hydrogen-on-tap system in the back of a Carmel, Indiana city truck. Beginning this summer, these pucks are going to power a few trucks in a town just outside of Indianapolis. After fourteen years of R&D and five iterations of his system, the idea is really starting to float. Koehler is the founder of Indiana-based startup AlGalCo - Aluminium Gallium Company. Kurt Koehler has a better idea: make the hydrogen on demand, in the vehicle, using a solid catalyst and a simple chemical reaction. They also need pressurized tanks to store the gases and pumps for refueling, all of which adds weight, takes up space, and increases the explosive potential of the system. The reality is that hydrogen vehicles usually need fuel cells to convert hydrogen and oxygen into electricity. On paper, hydrogen sounds fantastic - it’s clean-burning with zero emissions, the refuel time is much faster than electric, and hydrogen-fueled vehicles can go longer distances between refuels than their outlet-dependent brethren. 07 h2 air doc free#In the race toward a future free from fossil fuels, hydrogen is rapidly gaining ground.
