Most large-scale ammonia production typically relies
on natural gas or coal, which causes harmful carbon pollution
to enter the atmosphere. The viability of a small-scale “green”
ammonia plant is investigated where renewable electricity is
used to provide hydrogen and nitrogen via electrolysis and air
liquefaction, respectively, to a Haber-Bosch system to synthesize
ammonia. A green ammonia plant can serve as a demandresponsive
load to the electricity distribution system and provide
long-term energy storage through chemical energy storage in
ammonia. A coordinated operational model of an electricity
distribution system and an electricity-run ammonia plant is
proposed in this paper. Case studies are performed on a modified
PG&E 69-node electricity distribution system coupled with a
small-scale ammonia plant. Results indicate the ammonia plant
can adequately serve as a demand response resource and positively
impact the distribution locational marginal price (DLMP).

Budget-Constrained Sizing of Renewable and Energy Storage Systems for Farm-Scale Ammonia Production Within the Food-Energy-Water Nexus
AbstractÐIn the transition toward sustainable agriculture,
farms have emerged as eco-friendly pioneers, harnessing clean
hybrid wind and solar systems to improve farm performance. A
concern in this paradigm is the effective sizing of renewable
energy systems to ensure optimal energy use within budget
considerations. This research focuses on optimizing renewable
energy sizing in small-scale ammonia production to meet specific
farm demands and enhance local resilience, emphasizing the
interplay between environmental and economic factors. These
findings promise increased energy efficiency and sustainability
in this innovative agricultural sector. Additionally, our approach
considers small-scale ammonia plant needs and the dynamic
relationships between ammonia, water, and farm demands. Simulations
demonstrate substantial cost savings in farm electricity
consumption. Specifically, scenarios with renewable energy integration
in the farm can reduce at least 13% electricity cost
compared to a grid-dependent system in the 15-year simulation.

The purpose of this work is to quantitatively compare the energy cost of design alternatives for a process to produce ammonia (NH 3 ) from air, water, and renewable electricity. It is assumed that a Haber–Bosch (H–B) synthesis loop is available to produce 1000 metric tons (tonnes) of renewable NH 3 per day. The overall energy costs per tonne of NH 3 will then be estimated at U.S.$195, 197, 158, and 179 per tonne of NH 3 when H 2 is supplied by (i) natural gas reforming (reference), (ii) liquid phase electrolysis, (iii) solid oxide electrolysis (SOE) of water only, and (iv) simultaneous SOE of water and air. A renewable electricity price of U.S.$0.02 per kWh electric , and U.S.$6 per 10 6 BTU for natural gas is assumed. SOE provides some energy cost advantage but incurs the inherent risk of an emerging process. The last consideration is replacement of the H–B loop with atmospheric pressure chemical looping for ammonia synthesis (CLAS) combined with SOE for water electrolysis, and separately oxygen removal from air to provide N 2 , with energy costs of U.S.$153 per tonne of NH 3 . Overall, the most significant findings are (i) the energy costs are not substantially different for the alternatives investigated here and (ii) the direct SOE of a mixture of steam and air, followed by a H.–B. synthesis loop, or SOE to provide H 2 and N 2 separately, followed by CLAS may be attractive for small scale production, modular systems, remote locations, or stranded electricity resources with the primary motivation being process simplification rather than significantly lower energy cost.more » « less

To address the effects of climate change, it is imperative for economies to proactively invest in, and deploy, low carbon energy technologies to meet current energy demands. To this effect, several states in the U.S. have implemented policies to incentivize the growth of renewable energy technologies. One of these policies is the renewable portfolio standards (RPS), which mandates that a certain percentage of the total electricity sales of utilities be sourced from renewable energy sources. This paper examines the effectiveness of these policies in driving the growth of specific renewable technologies across different regional transmission organizations (RTOs). It evaluates the adoption of renewable energy technologies across these RTOs to provide insights on the varying successes of these policies. The paper develops a ranking system for the correlations between the strength of RPS and renewable energy capacity growth across the RTOs. Two central observations emerge. First, despite the presence of positive correlations between RPS and renewable energy capacity additions, the capacity growth of renewable energy is not monotonic in time as technological differences characterize regional attributes. Second, the technology returns on RPS mandates are location-specific.more » « less

Determining Reserve Requirements for Energy Storage to Manage Demand-Supply Imbalance in Power GridsProper integration of energy storage systems (ESS) into existing or future grids will depend on the effectiveness of models which seek optimal placement and sizing at the transmission and distribution levels. Current literature reviews reveal sizing methodologies can be improved to ease infrastructure integration, and those works with models useful for planning focus solely on micro-grids, wind power and forecasting, photovoltaics, or small communities. It is of interest to create an efficient, reliable ESS sizing model for large scale grids that contains interpretable models, has less sensitivity due to low model uncertainty, yet still is dependable due to an imposed reliability criterion. This work determined the minimum feasible size ESS to satisfy reserve requirements for a power grid with a high penetration of renewable sources. Results showed imposing a reliability criterion through loss of load expectation (LOLE) and energy index of reliability (EIR) resulted in more conservative capacity needs.more » « less

The storage of renewable energy is the major hurdle during the transition of fossil resources to renewables. A possible solution is to convert renewable electricity to chemical energy carriers such as hydrogen for storage. Herein, a highly efficient formate-piperidine-adduct (FPA) based hydrogen storage system was developed. This system has shown rapid reaction kinetics of both hydrogenation of piperidine-captured CO 2 and dehydrogenation of the FPA over a carbon-supported palladium nano-catalyst under mild operating conditions. Moreover, the FPA solution based hydrogen storage system is advantageous owing to the generation of high-purity hydrogen, which is free of carbon monoxide and ammonia. In situ ATR-FTIR characterization was performed in order to provide insight into the reaction mechanisms involved. By integrating this breakthrough hydrogen storage system with renewable hydrogen and polymer electrolyte membrane fuel cells (PEMFC), in-demand cost-effective rechargeable hydrogen batteries could be realized for renewable energy storage.more » « less
