摘要
长三角地区是中国地热能较为丰富的地区之一,广泛分布浅层地热能和中深层地热能。根据现有资料,采用体积法估算得到长三角地区3 km以浅的地热能(包括浅层地热能和中深层水热型地热能)总量达782亿t标准煤的热量,年可利用量相当于1.6亿t标准煤。可实现建筑物冬季供暖面积24.8亿m^(2),夏季制冷面积14.5亿m^(2)。然而,目前长三角地区利用地热供暖和制冷的建筑面积仅有0.57亿m^(2),不足可利用的4%,开发利用潜力巨大。按照上述地热能评估结果,若在长三角地区已有建筑物中可以最大限度的保障采用地热供暖制冷,可在现有基础上减排二氧化碳10%以上,若新增建筑均最大限度的采用地热供暖制冷,地热减排贡献可在20%以上,在碳达峰与碳中和目标的实现过程中做出突出贡献。
In the Yangtze River Delta,there are widely distributed shallow and medium-depth geothermal energy.Based on the geothermal geology data,we estimated the geothermal energy as 78.2 billion standard coal,and the annual recoverable amount is 0.16 billion standard coal,including both shallow and medium-depth geothermal energy.It has the potential to support space heating of 2.48 billion m^(2),and district cooling of 1.45 billion m^(2).However,there is currently only 57 million m^(2)area using geothermal heating and cooling,which is less than 4%of annual recoverable amount.Further,we showed that if the current district in the Yangtze River Delta could maximize the use of geothermal heating and cooling,the CO2 could be reduced 10%more than the current basis,and if the new buildings could all maximize the use of geothermal heating and cooling,the CO2 could be reduced 20%more than the current basis.Therefore,geothermal energy could play an important role in the target of carbon peaking and carbon neutrality in the Yangtze River Delta.
