传统氨合成工艺以煤或天然气等化石能源为原料，属于高能耗、高排放项目。绿氨指通过新能源发电后电解水制氢再合成氨，使原料轻质化，此路线可以实现氨生产过程的低碳或无碳化。传统合成氨的生产成本相对较低，电解水制氢由于需要电量较大，成本较高。研究发现，当新能源电价进一步降低或者利用弃光电风电来合成氨可提高绿氨的市场竞争力。随着"碳达峰碳中和"战略的实施，各国都在布局建设绿氨示范性项目，将促进氮肥原料的低碳化，同时合理利用新能源电力助力绿氨发展，并耦合氨发动机、氨燃料电池等技术的进步，绿氨在能源市场将迎来新的发展机遇。

The traditional ammonia synthesis process uses fossil energy such as coal or natural gas as raw materials, which consumes much energy and generates high emissions.Green ammonia, on the other hand, can be environmentally made from hydrogen produced by electrolyzing water through new energy power generation.This route reaches low-carbon or no-carbon emission in ammonia synthesis.However, the traditional ammonia synthesis process delivers a lower production cost, whereas the electrolysis of water for hydrogen production requires a large amount of electricity, finally causing a high production cost for ammonia.It is found that the market competitiveness of green ammonia can be improved by further reducing the electricity price of new energy or using abandoned photovoltaic wind power to synthesize ammonia.With the implementation of carbon dioxide emission peaking and carbon neutralization goals, all countries in the world are deploying and constructing green ammonia demonstration projects, which will promote the low carbon dioxide emission production of raw materials for nitrogen fertilizer.Meanwhile the rational use of new energy power can help the development of green ammonia and couple the development of ammonia engine, ammonia fuel cell and other technologies.Green ammonia will usher in a new leap-forward development in the energy market.
