The role of green ammonia in sector coupling and seasonal electricity storage

Zac CesaroRene Bañares-AlcántaraMatthew Ives November 11, 2021

Green ammonia (NH3) will have a versatile role in the decarbonisation of large sectors of the global economy. Of these sectors green ammonia will likely have the most competitive potential in decarbonising long-duration energy storage, regional energy and hydrogen transport, shipping propulsion fuel, and replacing existing brown ammonia production for fertiliser and other chemicals. In this presentation, we introduce our modelling on the cross-sector integration of green ammonia into large-scale energy systems, with a case study of India. In the power sector, ammonia may play a role in seasonal storage, system resilience, and electricity import/export. We co-developed the world’s first…

Green Ammonia Opportunities in Utility Resilience/Storage and Logistics

John PierceJason Kuzma November 10, 2021

The presentation will describe projects being undertaken in the Western United States utilizing low cost and redundant renewable energy resources to generate green hydrogen that would be converted to green ammonia; that ammonia will be utilized in various ways but will provide a readily available source of energy for use as an energy storage system by utilities (with a focus on municipal utilities) that will use these systems for energy resiliency and storage, as well as industry and consumer facing users such as fleet fueling (as ammonia, hydrogen, and electrical power for EVs), as well as maritime applications.

Renewable ammonia for grid-scale sustainable energy: Sector coupling for economic competitiveness

Matthew PalysMichael ReeseProdromos Daoutidis November 9, 2021

Ammonia produced from renewably sourced electrolytic hydrogen has considerable promise as a seasonal energy storage medium to enable high renewable penetration in the electrical power generation mix. Long duration energy storage via ammonia is significantly less expensive than using hydrogen or batteries [1,2]. Renewable ammonia can also be used as in its traditional application as a fertilizer to reduce agricultural carbon intensity. These multiple renewable ammonia use cases give rise to opportunities for sector coupling [3]. For example, an electric utility could deploy ammonia for energy storage while also pursuing additional ammonia production for sale in local agriculture markets. This…

Green Ammonia Production Integrated into US Wholesale Power Markets

Shaun Tuyuri November 13, 2019

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.

For decades, grid-scale energy storage has been used to balance load and demand within an energy generation system composed mainly of base load power sources enabling thus to large nuclear or thermal generating plant to operate at peak efficiencies. Energy storage has contributed over the time to meet peak demand and regulate frequency beside peak fossil fuel power plant who usually provided the bulk of the required energy. In the aforementioned context where inherent variability of the power generation asset was mainly a minor issue, energy storage capacity remains nevertheless limited for economic reason storing electricity during low electricity demand…

Large amount of water is a NH3 absorbent in the plant facilities for emergency. NH3 and NH4+ coexist in ammonia water. For example, potential of hydrogen (pH) is 11 in 2500 ppm ammonia water and the ratio of NH3 and NH4+ are 98% and 2%, respectively. The aqueous solution releases NH3 due to the high equilibrium vapor pressure, resulting in increase of the negative effects on the environment. Therefore, in order to reduce ammonia released to the atmosphere, sulfuric acid is added in the aqueous solution. In this case, ammonium sulfate is formed and dissolves in the water. Therefore complicated…
