Increased support rate for SCR

The NOx Fund aims to encourage more projects that use only SCR (Selective Catalytic Reduction) to reduce NOx emissions. Experience shows that the financial conditions for voluntary investment in SCR are challenging, with long payback periods of up to 10 years or more, even with a support rate of 70%. This is mainly because the savings from reduced NOx fees are primarily used to cover the costs of urea consumption and maintenance, leaving little to repay the investment. The NOx Fund has decided that the support rate for pure SCR projects can increase to 90% to make SCR measures more economically attractive.

SCR is still considered the most cost-effective measure for the NOx Fund, but it receives low support in relation to the NOx reduction achieved. This makes a potential increase in the support rate possible.

The assessment of an increased maximum support rate only applies to new applications. Each application for support for SCR installation will be evaluated individually to determine whether it qualifies for an increased maximum support rate of up to 90%. The evaluation will be based on whether the intention behind the increased support rate is met to trigger a measure that would otherwise not be implemented.

Support for other cost-effective technologies

The NOx Fund also allows other technologies with similar challenges to receive increased support. This applies to measures such as SNCR (Selective Non-Catalytic Reduction) in land-based industries and EGR (Exhaust Gas Recirculation) on engines, which may have long payback periods but are still cost-effective regarding NOx reduction.
