On February 13, 2026, the Netherlands Environmental Assessment Agency (PBL) presented its recommendations for the base amounts of the SDE++ scheme for 2026. In collaboration with TNO and DNV, the parameters for the upcoming subsidy round were established. For the bioenergy sector, the report provides important frameworks for scaling up green gas and using biomass for industrial heating.
With the confirmation that an opening round will take place in 2026, the SDE++ remains the main instrument for national CO2 reduction. The recommendation anticipates an inflation escalation of 6,7% for the period 2025-2028, which will lead to an increase in the basic amounts for various categories.
Justification for green gas and the 1,1 bcm target
The report extensively addresses the production of green gas, partly in light of the ambition to produce 1,1 billion cubic meters (bcm) by 2030. The PBL recommends base amounts that should cover the unprofitable portion of installations, such as thermophilic digesters with membrane technology.
A key factor in this recommendation is the inclusion of the Fuel Transition Obligation. The value of Renewable Fuel Units (RBUs) is explicitly included in the ranking of projects. This ensures that the subsidy closely matches producers' actual market revenues.
Focus on industrial heat and manure fermentation
In the heating sector, the PBL applies a clear boundary between high- and low-temperature heat at 100 degrees Celsius. Biomass installations will continue to play a role in supplying high-temperature heat to industry. In addition, there is specific attention for mono-manure digestion, where the avoided methane emissions from manure are included in a project's CO2 ranking.
For existing installations, such as sludge digestion plants that are being converted to green gas production, the PBL also provides advice to ensure the continuity of these production flows.
Timeline and budgetary frameworks
While the PBL provides the technical foundation, the Ministry of Climate and Green Growth (KGG) determines the final parameters and budget. The SDE++ 2026 grant application process is expected after the summer, with projects being ranked based on their subsidy needs per ton of CO2 reduction.
Entrepreneurs can use this advice as a guideline for their investment decisions, as the report contains the most up-to-date economic principles for renewable molecules and heat.
