Water and energy are two scarce and concerning resources interconnected in the closed-loop water-energy nexus, exemplifying the co-dependence of water and energy production. In this article, we investigate the interaction between the industries of these two resources and model it as a simultaneous game. We consider a supply chain that consists of water suppliers (WSs), power suppliers (PSs), and consumers of these commodities. In the supply chain, WSs purchase power from the power market, and PSs purchase water from the water market. Other consumers can also buy these resources at the water and power markets. The prices of these commodities depend on their quantities supplied to the markets. Each firm tries to maximize its own profit, in doing so the suppliers of water and power decide their production quantities. In this research, the Nash equilibria of the firms are determined and a comparative statics is performed on various economic measures. When there are multiple equilibria, the analysis finds the Pareto optimal equilibrium. We find that when there is sufficient supply to meet the demand of both industries and consumers, improvement of production technology improves social welfare and other economic measures of the supply chain. We also find that higher competition in either industry improves all economic measures. However, when either water or power supply is solely consumed by the firms in the cross industry, improvement of technology and higher competition can have a negative effect on some measures.

Offshore wind is playing an increasingly important role in our energy mix as it provides the opportunity to increase the penetration of wind energy considerably beyond the current capacity of land-based wind resources. While most planned offshore wind projects consider constructing the wind farms relatively close to the coast, there is vast untapped potential over the open ocean where wind velocities are significantly higher. However, transmitting electricity generated far from shore to onshore demand points is a major challenge since using submarine power cables for long distances can be prohibitively expensive. To address this challenge, we consider using offshore wind energy to directly produce green ammonia that can then be transported to shore via ships or pipelines. This is technically feasible since electricity-based production of ammonia only requires water and air as input materials. We perform a comprehensive techno-economic analysis for such green offshore ammonia plants, determining the minimum achievable levelized costs of ammonia for various wind profiles, plant capacities, distances to shore, and water depths. Our results indicate that the proposed approach has the promise to be cost-competitive, especially when considering expected cost reductions in offshore wind turbines in the foreseeable future.
