Sino Group, Arup, and the Hong Kong Polytechnic University announced the first research of a building hydroelectric system. The system recovers the head of the building that should have been lost and uses it as hydroelectric power. Preliminary studies have shown that the system can produce electricity in an environmentally friendly and low-cost manner while effectively reducing carbon dioxide emissions. The results are encouraging.
Xinhe Group, Mr. Huang Yongguang, is pleased to cooperate with the Hong Kong Polytechnic University and Arup's engineering consultants in the development of the first building hydropower system; the process fully embodies the vitality, creativity and team spirit of the young research team.
The hydroelectric power plant was installed in the second phase of Olympian City. It is a new-generation system that produces 100W per hour, which is a 6-fold increase in performance over the first generation. The system incorporates a turbine developed by the Hong Kong Polytechnic University and the Water Supplies Department. When the water flows through the water pipes, it drives the turbine and converts it into electricity. The generated electricity will be stored in the battery, enough to cope with the lighting system of the general elevator lobby. Suppose an elevator lobby is equipped with 15 LED bulbs, each power consumption is 6.5W, equivalent to saving HK$3.51 per day in each elevator lobby or saving HK$1,281.15 per year. The annual reduction of carbon is about 700 kilograms, which is equivalent to planting about 30 trees.
Professor Yang Hongxing, Director of Renewable Energy Research Department, Department of Building and Equipment Engineering, Hong Kong Polytechnic University, cooperates with Sino Group to develop related systems. Professor Yang Hongxing believes that hydropower generation is recognized as an environmentally friendly and low-cost power generation method. The main advantage of the system is that it can recover the water head that should have been lost to generate electricity, so it will not affect the supply of fresh water to the building. It is a desirable and sustainable solution.
In addition to being the first hydroelectric plant to be used in a building, the project is also the first of its kind in the commercial sector and academia. The results of this study have a profound impact on Hong Kong’s R&D projects that promote environmental benefits.
Arup's engineering consultant, Dr. Tang Zhenquan, added: “The flowing water in the pipeline has a lot of energy, and Hong Kong has a robust and sophisticated water conservancy facility that can be used to produce electricity in a sustainable way. Hong Kong’s per capita electricity is medium The energy saving potential of high-rise buildings in the city is high. Building hydropower has great potential for development and it also helps reduce the reliance on fossil fuels."
The data collected in this study will be the basis for the study of the next stage of the hydropower generation system. All parties will cooperate in the research and development of the third-generation hydroelectric power generation system to further recover the water heads that should have been lost in the building's water pipes, including waste water, increasing the amount of electricity generated, and at the same time it is applied more widely.
Mr. Huang Yongguang, an executive director of Sino Group, stated: “We are very pleased to be able to work with the Hong Kong Polytechnic University and Arup's engineering consultants to bring innovative ideas to fruition. The process fully embodies the innovation, creativity and creativity of young research teams from Hong Kong and Mainland China. Team spirit: The Group supports the concept of helping youth development, education, environmental protection, innovation and technology and building a better community. We will continue to work with universities in Hong Kong and the Mainland, hoping to inspire more innovative solutions and make our buildings more environmentally friendly. And for future innovation."
Mr Wong concluded: “Like other developed countries and big cities, Hong Kong needs to adopt new thinking and quickly respond to issues such as climate change and landfills. As a good corporate citizen, the Group has been committed to building a greener community. The property has implemented a series of environmental protection measures, including recycling and source separation of waste, and launched a kitchen waste management plan to upgrade the first high-efficiency kitchen kitchen in Hong Kong to handle 500 kilograms of kitchen waste per day. It also cooperates with local colleges. To study the use of microalgae to purify the kitchen residue filtrate, we are pleased to have succeeded in reducing the carbon dioxide emissions of our properties by 24% from the level in 2008, which has exceeded our target. We hope that this cooperation will inspire more discussion in related areas. And research, and look forward to more scientific research projects that will bring greater benefits to the environment.†(after the middle)
