HOT|COOL NO. 1/2020 - "How to District Energize your City"

How do we get there? The joint strategic energy plan for the EPT33 municipalities recommends a Roadmap 2025 presenting 34 actions being implemented by 2025. The vision of fossil-free energy systems in 2035 and a fossil-free transport system in 2050 requires considerable effort from many parts. All elements must be brought into play.

The 34 initiatives in the Roadmap 2025 are organized in six focus areas covering the total energy system in the EPT33 municipalities. The focus areas are:

1. DISTRICT HEATING AND COGENERATION The conversion from fossil fuel to sustainable biomass is already well underway. With the planned projects, the conversion from natural gas and coal to biomass in the larger district heating systems is almost completed - no further action is needed here. The main challenges until 2025 are a reduction of greenhouse gas emissions from the remaining production units. The expansion of geothermal, solar, heat pumps and district heating boilers must be accelerated to prepare for a multi-strand supply and - in the longer term - a reduction of burning biomass.

3. THE POWER SYSTEM The electricity system plays a key role in energy conversion, as more wind power and solar cells enter the electricity system of the future. Electricity will account for a larger share of the total energy consumption - and an increase in electricity consumption of

4. THE NATURAL GAS SYSTEM Natural gas is well suited to serve critical functions in the energy system. The main challenge is a conversion from cheap and abundant natural gas for expensive and limited biogas. There are limited amounts of biogas, so you should prioritize and use it strategically - for example in heavy transport and as peak load fuel in the electric and district heating system.

70% is expected in 2050 compared to 2015. The challengewill be expanding wind and solar to efficiency, flexibility, capacity, and balance, in an energy system with unstable sources.

6. ENERGY CONSUMPTION The energy consumption of buildings plays a key role in the energy system. As previously mentioned, they account for 40% of the total energy consumption in Denmark. Therefore, Roadmap 2025 has six specific measures reducing energy consumption in the building stock.
