报告摘要
A hydrogen economy has been the focus of researchers and developers for decades. However, the complexity of moving and storing hydrogen has always been a major obstacle to deploy the concept. Therefore, other materials can be employed to improve handling whilst reducing cost over long distances and long storage periods. Ammonia, a molecule with high hydrogen content, can be used to store and distribute hydrogen easily, as the molecule has been employed for more than 150 years for fertilizing purposes. Being a carbon-free chemical, ammonia (NH3) has the potential to support a hydrogen transition thus decarbonising transport, power and industries. Further, using ammonia directly can reduce costs and cycle inefficiencies. However, the complexity of using ammonia for power and heat generation relays on the appropriate use of the chemical to reach high power outputs combined with low emission profiles. Therefore, units such as gas turbines, engines, boilers and furnaces at various scales are currently under scrutiny for the direct use of ammonia as a fuel. Expertise on the subject is increasing to progress in the utilization of the chemical in an efficient, stable and low-polluting manner. However, progress comes with several challenges. Therefore, this presentation covers some global research that has taken place to understand the features of ammonia blends for powering energy systems whilst addressing challenges at various power scales for units that will support the transition to carbon-free fuelling in the power sector. Other areas such as aerospace are mentioned, whilst health and safety and public perception aspects of the use of NH3 will be also mentioned for further discussions.
