Växjö Energi - 100 % fossil free production of heat and power
![Country flag flag](/themes/custom/interreg/images/flags/se.png)
About this good practice
The municipality owned company Växjö Energi´s long-term investment in biofuels has strongly contributed to significantly reduce carbon dioxide emissions.
Resources needed
The availability of local bioenergy from forest residuals is a prerequisite for being 100 % fossil-free. CAPEX is higher when also the peak and reserve production of district heating has to be fossil-free.
Evidence of success
- The oil to be used to start the boilers have been converted to bio-oil.
- The two reserve facilities for heat production, located to various parts of the grid in the city, was rebuilt and now runs on bio-oil.
- The company´s emergency diesel generator has been converted to HVO, ie renewable diesel.
- The last partially fossil fuel-powered vehicles have been out-phased. Thus, all vehicles are powered by HVO, biogas or electricity.
- The loaders have all been converted to HVO.
Potential for learning or transfer
The use of local biomass as feed-stock is far beyond a possible option for all district heating providing companies. However the learning from this practise is the value of deciding for a goal and then decide targeted to reach the goal, it is about the mind-set, whatever the technical solution and the feed-stock look like.
