Important results from the project
** Denna text är maskinöversatt ** The purpose and objective of the project is to test and develop a system for generating power via a fuel cell and delivering power to the grid as well as a brewery with electricity. With this it follows that the total effect has decreased in the network as well as the network losses in the local network through a reduced power supply to the brewery. The goal has also been to enable a reduction in costs for the brewery regarding electricity when electricity costs are high, which the project has shown. The car has been used for the distribution and storage of hydrogen.
Expected long term effects
** Denna text är maskinöversatt ** - The system has been tested and works with high availability. - The local grid losses have decreased - Power has been delivered to the grid, which has reduced the need for other power in the grid - Hydrogen has been used as produced by renewable energy sources - Storage of electricity has been made possible in the hydrogen gas
Approach and implementation
** Denna text är maskinöversatt ** The experimental set-up consists of a fuel cell from a car that runs on hydrogen gas. From the car´s fuel cell, a direct current of approx. 25 kW is generated, which via an inverter converts the direct current into an alternating current of 400 V. From the inverter, the current can be fed out to the grid, alternatively to a heating tank for process water for beer brewing, or to both. the consumers. Fuel for the system is "obtained" from a hydrogen gas station and the car also functions as a fuel store. The value chain has been analyzed by 2 students from HIG
