TU Delft sets car on hydrogen street with electricity




TU Delft is Wednesday a fuel cell car from Hyundai to use in research into the efficiency and operation of supplying power to the grid if the car is not in use. The project car as a power plant is part of The Green Village, a “living lab”.

Delft University car as power powerplant A fuel cell vehicle is actually an electric car with a fuel cell on board which makes electricity from hydrogen and oxygen. On average, a car only five percent of the time used to drive around it. A parked car fuel can still produce electricity, which can be fed just to provide for example, homes with electricity. Other by-products of the reaction are water and heat.

The project Car shaft powerplant doing research on the optimization of everything associated with the drive and energy to produce hydrogen fuel cells. This means the entire chain of production and refueling, the lifetime of the fuel cell and the connection of the cars on the grid.

Leendert Verhoef of the Green Village project submits to Tweakers out that it is very important to do this kind of research with various parties and not just in a laboratory. It can change a lot of thinking about energy, he explains. “Where your tank? Who earns money to? Will you suddenly make money to park instead of spending it? Do not forget that there are more products coming out of such a vehicle, such as water and heat. For example, we also watch or beat the heat and is used, then the return is suddenly much greater. ”

The yield question can be answered in part by following the chain. Hydrogen can be obtained in various ways, such as from natural gas, biomass, or by an excess of wind and solar energy to be converted into hydrogen as a carrier of that energy. The latter is especially useful so that the unused energy is not lost, even with a relatively low efficiency advantage. Verhoef gives an example of how electricity is generated in the Netherlands: that happens mainly with natural gas, coal or oil. The efficiency of the whole chain is around 35 percent. If natural gas stream is converted to hydrogen, the yield is up to ten percent higher, between 40 and 45 percent.

The fuel cell car, a Hyundai IX35FCEV, delivers 100 kW, which is enough energy for about a hundred homes. The car is not directly suitable for the supply of electricity to an external source. Verhoef thinks the university needs six months to a year to good to build the car.
