广东省天然气利用的竞争性分析

The Competition of Natural Gas Utilization in Guangdong Province

在目前可预期的各种能源价格下,分析了天然气在广东省与其他能源的竞争性。居民生活领域,天然气越来越受到电力的挑战。天然气用于大规模热水设备,其经济性不如空气源热泵。工业用气方面,天然气与柴油比,有较大的价格优势,与重油相比,有一点竞争优势。区域供冷方面,单就经济性而言,分布式能源不如直接用电制冷。交通领域,天然气车船相比于其他燃料的车船,具有很好的环保性和经济性。由此提出了广东省天然气利用的方针。

Under the expectable prices of all types of energies, the competition of natural gas utilization in Guangdong Province with other energies is analyzed. For domestic users, natural gas is under the competition of electricity. For hot water service, natural gas boilers cannot compete with air source heat pumps. For industrial users, natural gas has great price potential than diesel and tiny price advantage on heavy oil. For regional cold supply for air conditioning, in the economic sense, distributed energy supply with natural gas is no better than regional cold supply with electricity. In the transportation sector, natural gas （or CNG,LNG） as fuel for vehicles and vessels has great environmental and economic benefits than other fuels. The guidelines for natural gas utilization are then proposed based on the above analysis.
