Vätgasens möjligheter inom lantbruket

Abstract: The aim of this report is to dimension a system consisting of solar panels, hydrogen production and hydrogen storage in order to make a small farm self-sufficient for all its energy needs in two different scenarios. In scenario 1, the total energy use consists of the electricity consumption on the farm and one hydrogen-electric hybrid tractor in operation. In scenario 2, the energy needs include the farm’s electricity consumption and the possibility of operating two hydrogen-electric hybrid tractors or selling the excess hydrogen. The simulation resulted in that scenario 1 will need 340 solar panels to be installed with a total installed effect of 134.3 kW, and for the second scenario 500 solar panels need to be installed with an installed effect of 197.5 kW. The hydrogen production plant in both scenarios requires battery of 60 kWh, an 150 kW electrolyzer, a 40 kW fuel cell and a storage of 8250 litres to meet the annual energy demand of the farm. The total cost for this system is calculated to be 16,48 - 26,06 MSEK depending on the choice of fueling station and the amount of solar panels installed. The greenhouse gas emissions from the farm are expected to decrease with 60 % when one hybrid tractor is used and 92 % when two hybrid tractors are used instead of the tractors powered by HVO100.
