For reducing CO2 emissions on a scale significant to the climate, it is not enough to encourage people to eat vegetarian food on Wednesdays or to dry their laundry outdoors. CO2 reductions, at scale, are achieved by integ FLY GREEN! Airplanes, trucks, and cargo ships that do not emit CO2. Does that sound like future music to your ears? The Jumbo jet Denmark is in the air and is on its way to the green future where DISTRICT HEATING can tie it all together. District heating can ensure that the sustainable future becom Figure: www.audi-mediacenter.com post edited by DBDH This far so good enough about the theory. Here are a few highprofile examples of green transition planning, being launched in Denmark, and where sectoral integrating and district heating are to ensure it all becomes cheaper and greener. eFuel Denmark kills two climate birds with one stone Waste incineration emits a large amount of CO2. And from the political debate, one could very well get the impression waste incineration is the greatest environmental sins of all. But that picture is misleading. At a modern waste cogeneration plant, the Illustration: BIG Carbon Capture at a waste incineration plant in Copenhagen Amager Resource Center (ARC), the owner of CopenHill (the cover image), burns the non-recyclable waste to produce electricity and heat for the capital region. The smoke is cleansed from more than 99% of the harmful particl Heating and cooling data for all of Europe M A T P O S H Although there are several tools for project feasibility studies, few software programs provide data and scientific calculation methods to perform strategic energy planning at a city or regional scale.

Investing in electric kettles or electrical driven boilers as they are called this size are an important part of the CTRs CO2 neutral strategy combining heat and electricity systems using wind turbines. Read this article and find out why! By Jan Hindsbo, THE TOTAL CAPACITY IN CTR IS 2100 MJ/S In a case of a shutdown, or in peak load situations, CTR has 1040 MJ/s of peak load and reserve capacity (ultimo 2020): 450 MJ/s of gas-fired boilers Next step... 470 MJ/s of oil-fired boilers 120 MJ/s electrical boilers Integrating more green and sustai The future Peak Load Stations The future PLS must be CO2 neutral, fast response, cheap in investment, and, as the full-load operation hours are low, the variable production cost is of minor interest.

Jan Strømvig, CEO of DHF is excited about the collaboration with Facebook: We are subject to the Heat Supply Act, so we must produce the heating as cheaply as possible for our consumers. We cant take part in projects if leading to high 100% renevable energy A plan for the 4th largest city in Denmark By: Jakob Zinck Thellufsen & Henrik Lund, Department of Planning, Aalborg University District heating and cooling infrastructures are essential for a green transition. To make it happen cities and municipalities play a crucial role as Aalborg District Heating Other District Heating Buildings Roads Aalborg Municipality Mapping supply and demand Aalborg is no independent island dispatched from the rest of Denmark but is balancing an energy system in a national and global context. This requires mapping all energy sectors nationall Identifying energy demands now - and for the future Wind and solar For identifying heating demands, a local geographic analysis mapping district heating, individual boilers, and heat pumps were made. The analysis included energy efficiency measures and the costs of implementing energy savings in b For fuel production, electrolyzers produce hydrogen which can be stored short term in hydrogen storage, but else is converted into fuel or gas to be used in industry, peak load power plants, or the transport sector. Finally, the wind is also integrated into the transportation sector through electric Low carbon emissions with low temperature zones Europe has the ambition to utilize district heating (DH) as the backbone of the energy transition because it can store energy from unstable renewable energy sources like wind and sun, necessary for reducing the CO2-emissions by 40% in 2030. By: Carste Lowering the supply temperature in parts of the district heating grid saves energy and makes it easier to utilize green energy. The solution was Grundfos iGRID. It lowers the supply temperature locally in specific zones of the grid. To do so a local mixing loop pumps water from the return pipe into Low temperature - high gain Based on Euroheat & Power country statistics 2017, the energy in the European DH networks is approximately 415 TWh. Assuming temperatures in half of the grid in zones with a current heat loss of 20%, could be lowered by 20C, this would lead to a potential heat loss reduct iGRID is an end-to-end solution reducing heat losses in district heating zones through real-time temperature optimisation. The next versions include heat pumps (HP) for the low-temperature zones enabling surplus energy connected to the DH locally. HP can increase capacity and lower carbon emissions SEAWATER REPLACES COAL By: Claus A. Nielsen Business Development Director, DIN Forsyning In 2018, the Danish parliament decided to phase out coal in Combined Heat and Power plants (CHP) by 2030. However, it was not fast enough for Ørsted, the owner of the CHP plant in Esbjerg. They wanted to phase Seawater replaces coal In September 2023, the work begins in the port of Esbjerg. Construction of a large seawater heat pump station. A biomass heat plant will follow, replacing the coal-fired CHP for DH. - We don't want to build one large unit depending on for the next 30 years.
