The HyLOG project
HyLOG - Hydrogen powered Logistic System
The ambitious aim of this project was to successfully implement an emission-free and efficient logistics operation within a real industrial environment - in this case at the Fronius Sattledt site in Upper Austria.
Double the energy density, yet zero emissions
Five logistics trains are currently in use at Sattledt to transport materials to more than 600 workplaces in two-hourly cycles.
As part of the HyLOG project, one of the transport vehicles was converted to run on hydrogen produced from solar power. The conventional lead/acid batteries in the vehicle were replaced by the Fronius Energy Cell with a replaceable hydrogen cartridge as the fuel tank. So several hours of battery charging have been replaced by just the few minutes needed to replace a spent cartridge.
The most impressive outcome from this innovative solution is double the energy density of conventional lead/acid batteries, but also double the vehicle range!
A totally regenerative energy supply and storage system
The hydrogen used for the HyLOG vehicle is produced by Fronius in-house via an electrolysis process powered by a 615 kWp PV system on the roof of the building. The hydrogen is then stored and made available for refueling via an in-house filling station infrastructure. The fuel cell drive integrated into the vehicle is used to convert the hydrogen into energy to operate the vehicle. This project was honored with the World Energy Globe Award 2007.
The Fronius Energy Cell as a zero-CO2 logistics solution
(1) A 615 kWp PV system erected on-site provides the solar energy.
(2) The inverter converts the solar energy into AC power.
(3) The Electrolyser converts AC power into hydrogen.
(4) Using a standard hydrogen filling pump the hydrogen gets condensed.
(5) The cartridge is completely filled in just a couple of minutes.
(6) The extremely efficient Fronius Energy Cell then converts the hydrogen into electrical energy in the vehicle (7).
This concept represents the successful implementation of a closed energy loop - completely emission-free and, in particular, without generating any CO2.
