This project is a collaboration between the Vennerslund Estate and DTU, initiated and financially supported by DTU Link, and with participation from DTU Wind Energy and DTU Electrical Engineering. The purpose of the research at DTU is to map the energy consumption at Vennerslund and evaluate scenarios that reduce the corresponding CO2 footprint. Scenarios include the erection of 6 wind turbines and a large PV plant, the installation of EV charging stations, the substitution of diesel- and straw-powered engines with electric alternatives.
• The area of the Vennerslund Estate allows for 6 wind turbines of 4-5 MW capacity each, yielding a yearly production of around 90 GWh.• A solar PV plant of around 45 MWp could also be installed, yielding a yearly production of around 53 GWh.• In total, around 770 ton CO2 is emitted every year at Vennerslund via the three main activities at the farm: running diesel-power machines, heating houses with a straw-fired boiler and drying seeds and grains with electricity from the grid.• The hybrid power plant consisting of wind and solar PV could provide a CO2 reduction of 28,520 ton per year if replacing the grid with a current CO2 footprint of around 200 g/kWh. This would hugely compensate for the current CO2 emission of the farm itself.• Current heating with a straw fired boiler could be replaced by a heat pump.• Current diesel-powered machinery could not readily be replaced by machines powered by alternative fuel such as electro fuels, bio fuels or electricity, due to lack of maturity for farming equipment of the required size. However, some tasks may be carried out by battery-driven electric tractors and this case is examined in detail.
Agriculture is a significant contributor to greenhouse gas emissions in Denmark and will need to be mitigated if national climate targets are to be reached. However, it is a major challenge to reduce the emissions from agriculture in an way that is economically feasible for farmers. Introducing local energy production with wind or solar PV plants is an investment that over the years turns into an income while providing green electricity to local farming activities. This projects examines the possibilities at one agricultural business in particular, the Vennerslund Estate in Lolland-Falster, in terms of energy production and CO2 emission reductions.
