Net environmental impacts of low-share wood pellet co-combustion in an existing coal-fired CHP (combined heat and power) production in Helsinki, Finland

摘要: Abstract The EU's energy sector depends heavily on fossil fuels, which contribute to climate change. This is why mitigation targets for production have been set, including an increased biomass use requirement. In Finland, commonly utilised but its capital, Helsinki, still dependent fuels. With the ambition of becoming neutral by 2050, Helsinki testing, inter alia, low-share wood pellet and coal co-combustion in a CHP (combined heat power) plant. objectives this paper were assess net environmental impacts changes urban air quality connected transport, identify hotspots relevant possible future higher-share co-combustion. applied methods screening LCA (life cycle assessment) fine particle dispersion modelling. results prove that leads impact reductions does not deteriorate environment. If be implemented, focus would operational issues power plant origin sustainability aspects production.
