Nethersole Hospital to use methane gas from landfill in green power plan
By Elizabeth Cheung, South China Morning Post.
Alice Ho Miu Ling Nethersole Hospital in Tai Po plans to use landfill gas to generate electricity in an attempt to go greener.
It is the first hospital to trial the alternative energy supply. It will cost HK$13 million for installation and the system is still being designed. It is expected to be ready for use in July next year.
A generator will be used for a combined heat and power system. While it produces electricity, waste heat at a temperature of 500 degrees Celsius from the generator's exhaust will go to a boiler to produce steam. Waste heat from generator cooling will also be used in a heat exchanger for hot-water supply.
