When I saw how many biomass-based CHP plants were pre-qualified in the current Danish CCS tendering process before the holiday, I became deeply worried. Why? Because we already use far too much biomass in power plants. Adding CCS further reduces flexibility at a time when we need the opposite.

The Danish government has announced a major cut in the electricity tax – from 72.7 øre/kWh to the EU minimum of just 0.8 øre/kWh in 2026 and 2027.
For households, this means significant savings:
A typical family: ~4,000 DKK less per year
Pensioner couples: ~2,700 DKK less per year

🌞 Solar power helped Europe pass the heatwave “stress test” 🔌
As temperatures rose in Europe at the start of July, so did electricity demand, driven by the growing need for air conditioning. In Spain alone, demand rose by 14% during the heatwave, pushing power prices >€470/MWh in some countries.

The Strait of Hormuz and Danish use of biomass
Denmark’s reliance on 200 PJ of biomass - nearly 30% of national energy use -is not a model to follow. It should be 30–40% lower. If the Strait of Hormuz were to close, oil and gas prices could spike dramatically.
