Green Ammonia Production Integrated into US Wholesale Power Markets

Shaun Tuyuri

The High Plains and Rocky Mountain regions of the United States have some of the best renewable energy resources in the world. As more non-dispatchable wind and solar generation is integrated into the power system, it is impacting wholesale power markets. Average wholesale electricity power prices are falling while their volatility is increasing. This creates opportunities for large flexible loads that are capable of consuming energy while prices are low and not consuming energy when prices are high. Result from an analysis of dispatchable fully electric ammonia production integrated into the power system are presented.

Ammonia is recognized as the new energy carrier and it is expected to be introduced into the society in a short time, since the infrastructures related to the ammonia, such as the mass production, transportation and storage are already introduced to produce the fertilizer for the agriculture. There is one technical issue, to use the ammonia in the direct combustion as the fuel for the electric power generation. It is the increase of the NO concentration in the exhaust gas. Ammonia contains the large amount of the nitrogen, comparing with any other fuels that human being has ever treated. Nitrogen…

JGC Corporation demonstrates "world's first" carbon-free ammonia energy cycle

Trevor Brown January 04, 2019

In late 2018, JGC Corporation issued a press release to celebrate a "world's first" in ammonia energy, demonstrating at its pilot plant in Koriyama both "synthesis of ammonia with hydrogen produced through the electrolysis of water by renewable energy, and generation of electricity through gas turbines fueled by synthesized ammonia." By demonstrating the feasibility of using ammonia on both sides of the renewable energy equation -- first, producing green ammonia from intermittent renewable electricity and, second, combusting this carbon-free fuel for power generation -- the project demonstrates the role of ammonia in the "establishment of an energy chain ... that does not emit CO2 (CO2-free) from production to power generation."

Ammonia is paid special attention as renewable energy carrier [1-3], because it offers advantages in generation, transportation and utilization. Haber-Bosch method is already established as ammonia generation method; large amount of ammonia is already used as fertilizer and chemical raw material. Ammonia can be liquefied at room temperature. Its transport and storage system are already established. Ammonia is cheaper to transport than hydrogen. Ammonia can be used as carbon-free fuel in internal combustion engines as alternative to conventional hydrocarbon fuels. However, it has different combustion characteristics. For example, the nitrogen atom contained in the ammonia molecule, causes high NOx emission…
