It is one of the most effective means to implement renewable energy and benefit from heat and power coupling. But as you can read in this issue of Hot Cool, the DHC potential remains mostly unexploited glo The International Energy Agency IEA publishes a range of unique and detailed energy statistics worldwide. Here we share IEA data, giving you an outlook on the status and development of district heating and cooling in the World. The IEA reports and quality Data & Statistics are Copied and pasted by H The DHC outlook Today, district heating (DH) is far from everywhere and only green somewhere. If DH is the first step, the next step is the green DH transition a giant leap for mankind. In 2018, a little less than 6% of global heat consumption was supplied through DHC networks and is expected to i WEC World Energy Consumption* 14,280,000 ktoe = 166,000,000 GWh DHC RE Share 60,000 ktoe = 9,965,000 GWh 6% of WEC Renewable Energy in DHC 68,800 ktoe = 800,000 GWh 8% * IEA defines one tonne of oil quivalent: 1 toe = 11.63 MWh; 1 ktoe = 11.63 GWh 16% of WEC DHC 1.5% RE in DHC of USA's One third of all DH in the world is in Russia!

Throughout the last years, investments have been made into low-temperature heat storage to develop, optimize The scale is one factor of success for the PTES, meaning that a larger scale reduces the cost. On the other hand, the scale has also been one of the challenging factors. Existing PTES systems have surface areas of the insulating lid in the region of 10,00020,000 m2. The surface's size gives rise to REDUCE HEAT LOSSES WITH TEMPERATURE ZONES UP TO 25% HEAT LOSS REDUCTION EASY AND REAL-TIME MONITORING FULL CONTROL GRUNDFOS iSOLUTIONS PUMP CLOUD SERVICES GRUNDFOS iGRID IS A NEW SOLUTION FOR DISTRICT HEATING With this solution we fight heat losses and prepare for utilisation of renewable en By: Derek Leask, Executive Director Shetland Heat Energy and Power In a recent study of Shetlanders it was found that up to 44% of our DNA was of Scandinavian origin. That suggests a lot of Viking tourists formed strong relationships in the islands many years ago! Shetland was actually part of Denm The WTE plant was built with Danish expertise and came on line in 2000 and was owned and operated by the council. SHEAP was formed as a separate organisation and was financed and owned by the Shetland Charitable Trust (SCT) which uses funds derived from the Oil and Gas industry in Shetland to benefi www.dbdh.dk 13 The irony of this is that we now have a different challenge. As heat networks are embraced and new developments are encouraged the Shetland scheme has been in operation so long, the preservation and asset management of the network are now key priorities. Not to fall behind, SHEAP have initiated a re Through discussion with Morten at VEKS, we learned of the traffic light approach to network management. This is where areas of towns can be divided into high, medium and low risk. Weve adopted this approach at SHEAP and now have a planned intervention and renovation programme on our network for next By: Dr. Volker Kienzlen, KEA climate protection and energy agency Baden-Württemberg The state of Baden-Württemberg introduces compulsory municipal heat planning for the biggest cities in the state. For the first time, the cities have to develop a vision for their CO2-neutral heat supply 2050. The D This article will focus on the requirements for municipal heat planning. The results have to be submitted to the regional council, where an evaluation can be made. If the transition towards a carbon-free heat supply shall be successful, municipalities need a clear strategy. This strategy must be l District heating is the power grid's best friend By: Trygve Mellvang Tomren-Berg Norsk Fjernvarme (Norwegian DH association) The market share of renewable energy in the Norwegian heating market is almost 100 % and at the beginning of 2020 a national ban on the use of fossil oil for heating entered In the 1980s, large scale heat pumps, using sewage water as a source, were introduced in Sandvika, close to Oslo. Other cities followed, and similar heat pumps, most of them sea waterbased, are the backbone of several district heating systems in Norway today. Also, electrical boilers have been prese By: Alfred Heller, Civil Engineer, PhD, Chief Consulting Engineer, NIRAS A/S, Denmark Cooperation between mostly Danish partners, aiming at the next generation digitally supported district heating, is described in Hot Cool 2020 no.1.

But big dreams are hard to achieve even though plans are extens But as can be seen in the videos, the idea of securing benefits to different groups creates a strong planning platform with clear goals. Here I find the real value of good planning making sure we all know the basics of our decisions actually, no matter who we are in this sentence.

KMD was later on bought by NEC Corporation, which focused on the energy sector through their NEC Smart Energy Solution. KMD is among Denmarks largest IT companies, with br We thank you warmly for this year It has been a different year for all of us, however together, we have shown great flexibility in the journey towards green and sustainable district heating. Flexibility is also the key word for our Flextra program The lowest Total Cost of Ownership in relation to
