Hong Kong to develop renewable energy to reduce its carbon footprint
Renewable energy sources, electricity generation is the largest contributor to carbon emissions in Hong Kong, accounting for 66% of total carbon emissions in 2019, according to the city’s 2050 Climate Action Plan.
The special administrative region relied on imported fuel to generate electricity, or imported electricity from the Chinese mainland, to meet its electricity demand. With various initiatives to stimulate the development of renewable energy, Hong Kong’s energy mix for power generation has changed. In 2015, coal accounted for 48% of electricity generation, but the ratio fell to 24% in 2020. Over the same period, the ratio of natural gas in the energy mix increased from 27% to 48% . The contribution of nuclear and renewable energy has also increased, albeit slightly – from 25% to 28% – between 2015 and 2020, according to the 2050 Climate Action Plan. HKSAR The government expects the share of renewables in the energy mix for electricity generation to increase from less than 1% currently to between 7.5% and 10% by 2035, and to increase to 15% by the following. Zero carbon energy, or renewable energy, refers to energy sources that generate little or no carbon emissions when produced or used. These sources can be solar, wind or hydrogen. Hong Kong is developing renewable energy sources on all fronts. The government will strive to develop more advanced waste-to-energy facilities to generate electricity.
He is also considering proposals with the city’s two power companies to develop offshore wind farms and has encouraged the community to develop solar power. Waste accounted for 7% of the city’s total carbon emissions in 2019, according to the 2050 Climate Action Plan. no longer rely on landfills for municipal waste disposal, resulting in a high carbon footprint. Hong Kong’s drive to develop large-scale renewable energy sources still faces constraints due to geographical factors, scarcity of land resources and densely populated areas. Among zero-carbon energy sources, hydrogen is set to play a bigger role in the fight against climate change. Hydrogen is a versatile, non-toxic and light gas that can be stored, transported and converted into clean energy. More importantly, it has the potential to decarbonize a wide range of sectors. A clean and green economy can be developed when hydrogen can power a range of applications, such as chemicals, transport, buildings or manufacturing, if produced at scale. Gray (non-decarbonated) hydrogen, which is the most common form, is generated by carbon-intensive methods, using natural gas or coal feedstock; while green (carbon-free) hydrogen is produced from sustainable energy sources via methods such as electrolysis – a chemical reaction that breaks down water into its building blocks, hydrogen and oxygen. Renewable energy sources, such as solar or wind power, can be used to generate green hydrogen. The Hydrogen Council – an international advisory body to foster the long-term clean energy transition – expects global hydrogen demand to reach 546 million metric tons by 2050, up from 70 million metric tons currently, with an annual growth rate of 6.4%.
