Future Production of Transport Fuel, Power and Heat from Biomass A Vision of a Large-scale Energy Combine in Göteborg

To reduce the emissions of the greenhouse gas carbon dioxide (CO2) to the atmosphere different measures can be applied, for example a reduced energy use and a shift from fossil fuels to renewable fuels such as biomass. An energy efficient way of utilising biomass could be for production of transport fuel, electric power and heat in a so-called energy combine. In this report a vision of how a large-scale biomass-based energy combine could be part of a future sustainable energy system in Göteborg has been developed. In order to determine the size of a energy combine, scenarios of the future demand for transport fuel, electricity and heat in the residential and service sector and the transport sector have been made. The method applied is the so-called backcasting approach, which is a method to analyse future options from a sustainability perspective. The sustainability criteria applied are that the energy system should not give rise to net emissions of CO2, that it is based on renewable energy sources and that it is characterised by efficiency, both on the supply and user side. A population increase of 35 % compared with today is also assumed. The imag
