In Aarhus, the focus is industrial energy efficiency. The technology development within heat pumps has in recent years reached a level where they can deliver, recover and upgrade industrial waste heat, reaching a necessary level to decarbonise thermal processes in industrial processes.
The applications range from hot water production to upgrading waste energy to be used in other industrial processes. The challenges of HTHP (heat pumps) are the integrability into the production process industry and to match the required heat demand. The HTHP seeks to substitute liquefied petroleum gas (LPG), fuel oil and natural gas with electrically powered HTHP based on a high percentage renewable energy mix. Any derivative investments in infrastructure followed by HTHP is excluded from this project.
The plan includes the development of a new infrastructure for bus transport, with three new bus routes. There will be a shuttle connection between the city and railway station using existing tracks. The cost includes rolling stock, signals, and tracks repairs amongst others. A new train station will also be built in Erritsø.
Generally, the plan is focused on creating better options for multi-modal transport, including the improvement of existing transport hubs and the creation of new hubs that are flexible and attractive to use, including secure bike parking and service facilities. One of the main impacts of the project is to reduce the use of privately owned cars due to more attractive transport solutions that this project may bring.
The investment concept include at least 5 technological themes: energy efficiency optimisation, electrification, district heating (DH), sustainable mobility, renewable energy. In industry, measures include energy efficiency in production, electrification of processes replacing natural gas and utilisation of waste heat to safeguard year-round utilisation of waste heat to reduce energy consumption for cooling and as input to district heating. In DH, measures include expanding the DH network, hence replacing the heating source for households from natural gas to efficient DH and utilising waste heat from industry to DH, hence replacing part of the natural gas driven heat production. Sustainable mobility involves citizens in the transition by installing charging stands for electric cars, electric bicycles on subscription, and charging stands for private electric bicycles to encourage green transportation. Renewable energy includes among others solar plants, wind, heat pumpe and ATES.
The project is based on previously identified energy saving potentials in the social housing sector and the main actions of the project are:
1.update of previous screenings
2. re-visit the housing associations to identify the status since the previous screening
3. identification of new potentials and calculation of savings for new measures and update of savings for previously identified measures, investments and payback times
4. preparation of a plan for the implementation of the energy saving measures and local RES production of each housing association.
5. presentation at meetings with housing associations and departmental interest groups and residents' democracy in those associations.
The expansion of the district heating grid and utilization of surplus can be accomplished with existing technology. The planned new expansion of the Port of Hirtshals however, is planned to include a Power-to-X plant that will utilize electricity produced by local wind turbines and convert this into hydrogen fuel for large ferries.
The investment case aims at enabling energy decarbonisation through low or zero carbon technology while increasing financing for decentralized energy production at the port. The Municipality of Hjørring wants to make sure that sufficient grid investment will take place, since it is essential for new, intermittent energy sources like wind and solar. Danish taxation system provides a unique opportunity to install solar panels on all existing buildings on the port, as these can be considered one block while being leased to individual companies. Under Danish law, this makes it favourable to produce and sell electricity via solar panels.
The investments will mostly target house owners and are divided into the following categories: renovations, renewable energy and heat pumps. For home renovations, the investment concept will focus on improving the climate shell of the building and isolation (wall, roof, floor and windows). This will amount to an investment of €10.000/house. As it concerns renewable energy, there will be solar panels installed on the homes - the investment of €9.000/house is foreseen.
The last measure is the conversion of the heating system to a heat pump system. This will amount to an Investment of €13.500/house if it concerns an individual home. In cases where an energy utility or private company builds a collective system in a village based on heat pumps, the investment will be €23.500/ house. Some house owners will implement more than one solution at the same time. In 15 municipalities, 200 house owners will choose to renovate, establish solar power and/ or change the heating system to a heat pump.
The TERMUN (Termonet in MUNicipalities) investment concept (IC) aims to accelerate the transition from fossil heating to heat pumps, but will not consist of one technical solution. TERMUN IC works across the different solutions possible for establishing solutions. A ‘thermometer’ is a supply network that transports thermal energy from different types of energy sources. The network runs across many homes/buildings with a typical temperature of between 0 and 10 degrees. The investment needed to build a solution contains but is not limited to tendering and analysis of potential, foreseeing pipes and pumps in a horizontal or vertical system for the brine system, installing heat pumps in private houses and creating service and billing systems.
Transition to renewable energy sources by producing enough green electricity to cover the need of electricity in the municipality (citizens, public buildings, businesses and industries). The main focus is PV technologies and solar cell parks.
The investment concept will be developed for a project titled WeCARe IC. Its objective is to transition the car fleet to electro mobility through the financing of technical measures such as Electrical Vehicles (EVs) infrastructure. WeCARe IC specifically identifies four relevant types of EV chargers with different charging speeds and properties, necessary to ensure a full transition to electro mobility. These are the residential charger (used for charging Battery EVs at houses and flat buildings), a commercial charger (retail and hospitality locations), a so-called Fast charger (usable for charging BEV at high speed, e.g., at workplaces, campuses, commercial parking spaces) and an “ultra-fast charger” used for charging BEV at very high speed, e.g., at highway stops.
The grouping applied consists of the following cities and municipalities: Frederikshavn, Skive, Ringkobing-Skjern, Horsens and Sonderborg og Hoje Taastrup.
The project aims to investigate and develop options for a biogas liquefaction according to the approved SECAP action to meet the ambitious climate plan for Samsoe municipality. The project will analyse investment into the innovative micro-scale liquefaction processes using purification and biogas upgrading, bio methane liquefaction and potential use of “waste” CO2.
The Investement Concept aims to accelerate the transition from fossil heating to heat pumps in TS whit local SP but will not consist of one technical solution for all TS. The Investement Concepts works across the different technically solutions possible for establishing a TS.
A thermometer is a supply network that transports thermal energy from different types of energy sources. The network runs across many homes/buildings with a typical temperature of between 0 and 10 degrees. Investment needed to build a TS contains but are not limited to:
• Tendering and analysis of potential
• Pipes and pumps in a horizontal or vertical system for the brine system.
• Heat pumps in private houses sizes is individually calculated
• Service and billing systems
• Solar parks
The TS can be in combination with geothermal heat pumps and excess heat from local factory’s’ being stakeholders in the system analysis of potential for local heat sources has a great impact.
