  This paper discusses the adoption of a green ammonia economy in meeting
challenges in China's sustainable development. First, key challenges in China's
energy transition, industry decarbonziation and regional sustainable
development are explored. The coal-dominated energy consumption has placed
great obstacles in achieving energy transition and led to massive CO2 emission
since the large-scale industrialization. The high dependency on oil and gas
import has threatened the energy security. A DEA model is applied for obtaining
green total factor productivities of China's six administrative regions, with
which, imbalanced and unsustainable regional development is identified. Second,
the role of green ammonia in meeting the sustainability challenges is analysed.
Ammonia is examined to be a flexible and economic option for large-scale
hydrogen transport and storage. Co-firing ammonia in coal power generation at
3% rate is evaluated as an option for achieving low-carbon transition by 2030.
The adoption of a green ammonia economy in China is discussed from energy,
environmental and economic aspects. The practice can decline fossil energy
consumption, enhance energy security, and facilitate renewable energy delivery
and storage, industry decarbonization, and regional development. We assume the
findings and results contribute to addressing sustainability challenges and
realizing a hydrogen economy in China.
