KAPSOM: What is green ammonia?

What is ammonia? Ammonia, also known as NH3, consists of one nitrogen atom and three hydrogen atoms, and is a colorless gas with a distinctive odor. It is found in the human body and in the natural environment – in water, soil and air, and even in tiny bacterial molecules. Ammonia and ammonia ions are important components of metabolic processes for human health. Ammonia is the most abundant alkaline gas in the atmosphere and is produced naturally through the decomposition of soil nitrogen-fixing bacteria and marine algae, as well as plant, animal and animal waste. What is green ammonia? In recent years, China has made remarkable achievements in the development and utilization of solar energy and wind energy. According to statistics, in 2019, 8% of the world’s electricity comes from solar and wind energy. China, the US and India are slightly above the global average. The European Union leads the way with 18% of its electricity from wind and solar, more than double the global average, and Denmark at 55%. Thermal energy has been widely used as a carrier for storing solar energy, such as solar water heaters and solar roof fans. Short-term decentralized storage equipment for solar and wind energy is likely to be successfully developed in the future, such as solar air conditioners using glycerin water solution to store energy, wind heating devices using molten paraffin to store energy, local low-voltage DC power grids, and devices that use solar and wind energy to directly charge electric vehicles . The “green ammonia” technology mainly uses the electricity generated by clean energy such as solar energy and wind energy to electrolyze water to generate H2, which then reacts with N2 to generate ammonia gas. It is a low-carbon or zero-carbon emission green technology. The mass fraction of hydrogen in ammonia gas is relatively high, 17.7%; at normal temperature and pressure, gaseous ammonia is easily converted into liquid ammonia; It is an ideal carrier for hydrogen energy for storage and transportation.
