本文以丹麦为例，分析了区域供热在未来可再生能源系统中的作用。目前，可再生能源的份额接近20%。从这一出发点出发，本文定义了一个情景框架，其中丹麦系统在2060年转换为100%可再生能源（RES），包括将空间供暖需求减少75%。通过对整个国家能源系统进行详细的能源系统分析，与燃料需求有关的后果，二氧化碳排放量和成本计算了各种供热方案，包括区域供热、个人热泵和微型热电联产。这项研究包括近25%的丹麦建筑存量，即那些今天有单独的燃气或燃油锅炉，可以用区域供热或更有效的单独热源取代的建筑物。从这样的整体角度来看，最好的解决方案是将逐步扩大区域供热与剩余房屋的单独热泵结合起来。这一结论适用于目前主要以矿物燃料为基础的系统，也适用于将来可能100%以可再生能源为基础的系统。
Based on the case of Denmark, this paper analyses the role of district heating in future Renewable Energy Systems. At present, the share of renewable energy is coming close to 20 per cent. From such point of departure, the paper defines a scenario framework in which the Danish system is converted to 100 per cent Renewable Energy Sources (RES) in the year 2060 including reductions in space heating demands by 75 per cent. By use of a detailed energy system analysis of the complete national energy system, the consequences in relation to fuel demand, CO2emissions and cost are calculated for various heating options, including district heating as well as individual heat pumps and micro CHPs (Combined Heat and Power). The study includes almost 25 per cent of the Danish building stock, namely those buildings which have individual gas or oil boilers today and could be substituted by district heating or a more efficient individual heat source. In such overall perspective, the best solution will be to combine a gradual expansion of district heating with individual heat pumps in the remaining houses. Such conclusion is valid in the present systems, which are mainly based on fossil fuels, as well as in a potential future system based 100 per cent on renewable energy.
