It is one of the most effective means to implement renewable energy, utilize surplus heat, and benefit from heat and power coupling. But, as you could read in the last issue of Hot Cool, the DHC potential By: Zhaohui Wang, Ph.D., CTO Shenzhen Qianhai Energy Technology Development Co., Ltd. The need for cooling in Asia rises fast and is demanding for the environment and the electricity supply. District cooling (DC) in Asia, especially in China but also in India, have tremendous market potentials. Com District Cooling development in India In India, installing cooling capacity across all technologies in use is likely to grow 4x over the coming decade to 296 MN Refrigeration Tons (RT), an 8% Compound Annual Growth Rate (CAGR). The fastestgrowing market sub-segment is Variable Refrigerant Flow (VRF) District Cooling development in China While district cooling (DC) still is at its beginning in India, the DC market in China is fast growing. In China, the district cooling market at present (5.9 TWh) is more extensive than both the Japanese (3.5 TWh) and European (3 TWh) markets and could reach the 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 A GREAT PLACE FOR SKIING A-GREAT PLACE FOR SKIING AND DISTRICT HEATING THE QUESTION: What role do district heating systems play in the energy transition, price competitiveness, and electricity demand management? And how does all this fit into a context of decarbonization? By: Albert Moles, CEO of - AND DISTRICT HEATING A heating system historically fuelled by gas oil Energy demand in Andorra is approximately 2,400 GWh/year. Electricity represents only 25% of this energy demand: the transport sector (people and goods) accounts for 50%, while 25% is consumed in heating. Until the early 2010s, Low national production, mainly hydro power Despite a small share of recovered energy and the introduction of photovoltaic power, national electricity production depends essentially on hydropower, with little storage capacity. During the months when the snow is melting, the country's energy meets 50 Description of projects managed, and value generated Future vision Accordingly, in 2014 an intense phase was launched for the construction of district heating systems, with specific projects closely adapted to the particularities of each different area. In order to manage the energy transition an Renewed focus on the green transition in the Unites States so far so good! But what about district energy...? The calendar shows March 2021. A renewed focus on green energy is a reality in the United States. The big question is what it actually means for the district energy (DE) industry and market DE is crucial in reaching carbon neutrality colleges are leading the way Federal funds for transformative clean energy open the door for D.E. The fact that low carbon DE is not high on the political agenda also has its advantages. Private actors mainly drive the DE sector without any fundamental Scottish venture into water-sourced District Heating at scale By: Michael McGuinness, Economic Development Manager, West Dunbartonshire Council How do we as a small nation contribute to the climate change emergency? What can a local authority public body do to reduce our Carbon footprint and provid The landowners convinced us their development partner could manage the build-out of a shell building. We tendered and secured Vital Energi to assist us in fitting out and running the pipework. Through Vital engaged with Star Refrigeration to build us two 2.6MW heat pumps, we call the twins to aim fo AMBITIOUS FIRST LEGISLATION ON DISTRICT HEATING A unanimous Scottish Parliament recently passed the Heat Networks (Scotland) Bill - the first legislative framework for district heating in the United Kingdom. By: Jacob Byskov Kristensen, Energy Counsellor, Embassy of Denmark, London Mathias Grydehøj But though much is still to come, the new Bill is widely celebrated by stakeholders and industry as a crucial element of increasing investor confidence in the sector. As an example, the Association for Decentralised Energy in the UK welcomed the Bill, saying: The Heat Networks (Scotland) Bill sets a Decarbonization of the Austrian District Heating Systems By: Ralf-Roman Schmidt, Edith Haslinger, Roman Geyer, Benedikt Leitner, Dragisa Pantelic One of the main climate goals in Austria is to reach carbon neutrality by 20401. The renewable share in district heating (DH) is currently at 48.4 %, of Best practice Vienna With about 1.7 million inhabitants Vienna is the largest city in Austria. More than 30 % of its buildings are supplied with DH. Its supply mix is dominated by gas CHP (52 %), waste incineration (21 %) and waste heat (18 %), while boilers, ambient heat and biomass account for the Significant contribution by geothermal energy and seasonal storages Currently, there are efforts to exploit deep geothermal resources in the Vienna Basin22. If successful, the renewable heat supply in Viennas DH network will be increased substantially. Since geothermal energy constitutes a base load Graz and Innsbruck Other cities are currently implementing innovative activities towards the decarbonization of their DH supply as well. Alone frontrunner is Graz, where the current fossil-fired CHP plants became uneconomic and almost 80 % of the overall DH supply has to be replaced. Therefore, the Ringsted DHCs heat recovery kickstarts a new era of greener district heating Ringsted District Heating Company (DHC), a large district heating utility in Denmark, has reduced its reliance on fossil fuels by 97% after installing an innovative heat recovery system using heat pumps. The heat pumps bui Higher heat recovery temperature and lower heat supply temperature result in higher heat capacity & efficiency The unique challenges of installing heat pumps at Ringsted DHC To get the highest heat pump efficiency, and lower the price of heat, Ringsted DHC needs to recover the heat at the highest Another challenge Geoclima and Unicool faced was the size of the equipment room where the heat pumps are installed like many district heating plants, its particularly narrow. This required Geoclima to design a dedicated pipeline and layout, to enable easy maintenance, modular usage, and quick parts M ember com p a n y p r ofi le : PERNEXUS SYSTEMS Smart data in supply chain management District city heating roll-out in Haderslev With a recently signed contract with Haderslev District Heating - on digitalizing and creating the ground for efficient district heating roll-out we expect to provide From electricity to heating or cooling - and vice versa!
