New Hydrogen Fuel Cells on German Roads

Everyone talking about electric cars. Linde, however finally bringing the fuel cells on the road. Summer roll 50 BeeZero Hyundai’s hydrogen units are powered by Munich Research Lab. Linde introduces at Hannover Expo the cars and improved tank technology for next generation cars.

According to the technology group Linde is the world’s first car-sharing fleet, which uses only fuel cell vehicles. Under the project name BeeZero should be available from summer 50 of emission-free cars in Munich. Interested parties can see the Hyundai ix35 fuel cell vehicles until Friday on the Hanover Expo and try it as desired. (Hall 27, stand B71).

Because the generation of hydrogen requires generally much energy, the fuel cell technology not rare as only mediocre is considered climate-friendly. Linde emphasises that the hydrogen used for the BeeZero fleet is produced completely with green methods, where renewable raw materials used are reticle. Thus, the concept is completely CO2-neutral. With a tank of gas the Hyundai should take 400 km hydrogen. The 136 PS of strong SUVs of to classic electric cars would allow a much higher range.

Two components for more efficient refueling

The problem: Similar as when electric cars there are only a few ways to refuel his vehicle with hydrogen. “The successful construction of a petrol station network is feasible only with intelligent and cost-efficient solutions in the refueling technology”, says Markus Bachmeier, head of solutions hydrogen at Linde.

Cryopump

Therefore, the group shows two components that promise greater efficiency in Hanover: an ionic compressor and a so-called Cryopump. Former, a liquid salt takes over many features of a conventional metal piston. Its advantages: The hydrogen cannot be contaminated by lubricants, also wear and space requirements are reduced and energy consumption.

CryoPump compresses hydrogen to 900 bar

The Cryopump allows a compression ratio of hydrogen to be used on up to 900 bar. In contrast to the Ionic compressor, the pump with cryogenic hydrogen works at liquefied minus 253°C. Thus is this component especially for applications where minimal space and low power consumption, high throughput is required.

At its stand, Linde shows including the so-called H2 bike: a fuel cell-powered electric bicycle. Unlike the SUV from Hyundai the wheel is but still not ready for production, but so far a prototype.
