Microgrids are among the promising green transition technologies that will provide enormous benefits to the seaports to manage major concerns over energy crises, environmental challenges, and economic issues. However, creating a good design for the seaport microgrid is a challenging task, considering different objectives, constraints, and uncertainties involved. To ensure the optimal operation of the system, determining the right microgrid configuration and component size at minimum cost is a vital decision at the design stage. This paper aims to design a hybrid system for a seaport microgrid with optimally sized components. The selected case study is the Port of Aalborg, Denmark. The proposed grid-connected structure consists of renewable energy sources (photovoltaic system and wind turbines), an energy storage system, and cold ironing facilities. The seaport architecture is then optimized by utilizing HOMER to meet the maximum load demand by considering important parameters such as solar global horizontal irradiance, temperature, and wind resources. Finally, the best configuration is analyzed in terms of economic feasibility, energy reliability, and environmental impacts.

Background: Ethiopia has been landlocked since Eritrea, a former province, gained independence. Its imports and exports by sea are now sent via neighbouring coastal states, mainly Djibouti, and it needs to ensure sustainable access to multiple transit corridors.Objective: This article aims to evaluate alternative transit corridors to Ethiopia in terms of basic port infrastructure, and logistics costs. The findings provide insights to inform policy on securing reliable maritime access to the country.Method: This study adopts a case study approach by using secondary data to evaluate alternative transit corridors. Following a critical review of theoretical and empirical literature, descriptive statistics are presented using tables, graphs and charts.Results: Low-cost, high-capacity and high-frequency global maritime freight trade is easier through Djibouti than through Mombasa in Kenya or Port Sudan, owing to its better liner shipping connectivity. Thus, Ethiopia should continue to import containerised cargo through the Port of Djibouti. However, direct access to the sea is also important for national defence and security.Conclusion: Ethiopia should therefore secure access through multiple ports to safeguard national security, regardless of economic feasibility. This can be realised by directing break-bulk, dry bulk and petroleum products through ports in Sudan and Kenya. In addition, particular emphasis should be given to seaports closest to the country’s economic centre, such as Berbera in Somaliland and Asseb and Massawa in Eritrea.

On account of severe water pollution condition, this paper combines structure emissions reduction, engineering emissions reduction and management emissions reduction (namely SEM emissions reduction), builds an optimization model for total amount control of regional water pollution, and puts the above model into practice to validate its validity and reliability. According to the case study, the emission reduction of COD and NH3-N are 43.94 and 7.09 (104 tons), respectively. The optimal total costs of reduction is 36.89 (billion yuan), which decreases 7.47% than the existed recommended scheme (39.87 billion yuan). This method can be used for providing technical support and thus achieves the 12th Five-year goals of the environment protection plan more effectively.
