NDH first to adopt ‘combined cooling, heat and power system’

Waste at landfills is not at all good for nothing. The landfill gas produced during waste decomposition can be utilised as a source of energy. Alice Ho Miu Ling Nethersole Hospital (AHNH) is the first public hospital in Hong Kong to use a ‘combined heat and power generating system’. The burning of landfill gas powers the generator and supplies electricity for two air conditioning units in the hospital, while the heat generated during the process can also convert into steam and hot water for the hospital. Since the installation of the system in 2016, AHNH has reduced 2,100 tonnes of carbon emission, and saved HK$2.3 million of energy cost per annum.

Yuen unveils that the North District Hospital (NDH) will introduce a new ‘combined cooling, heat and power generating system’ in the future. “It also utilises landfill gas to provide heat and absorption chillers to supply air conditioning, simultaneously provides heating, cooling and power generation. NDH is expected to save HK$5 million of energy cost and reduce carbon emissions by 3,900 tonnes per year. We hope to further reduce energy demand, realise the hospital’s sustainable development vision, and take the lead in the community towards carbon neutrality.”
