In December 2015 the NOx-fund decided to open for considering NOx-reducing measures in combination. This means that different measures with different levels of financial support (støttesatser), where one measure has an effect on the other, will be considered together. This means that batteries and SCR will be considered as one measure where the effect of the two and the cost of the two are combined. The 80 % ceiling for covering costs is based on the total cost of both measures. See the guidelines for applications on the NOx-fund webiste for more information.
