Decarbonisation of seaports: A review and directions for future research
Marine activities in seaports account for circa 3% of total carbon emissions worldwide, prompting several initiatives to decarbonise their energy systems and make seaports smarter and greener. This paper provides a thorough and authoritative review of the vast array of research in this field, including past and ongoing initiatives. The study reveals that existing research leverages recent advances in digital technologies while focusing on one or several of the following themes: carbon reduction, use of renewable energy resources, cost-performance optimisation, deployment of smart control technologies, the regulatory landscape for greening seaports, and implementing green port practices guidelines. As such, the paper provides a critical review of existing technologies and concepts that promote and contribute to the decarbonisation of seaports, including Smart Grids and Virtual Power Plants. Several avenues for future research are then discussed, including (a) total life cycle approach to seaport energy management, (b) Semantic-based modelling, forecasting and optimisation of seaports energy systems, (c) Secure and reliable seaports energy services, and (d) Transition towards prosumer-driven seaport energy communities. The paper concludes by emphasising the importance of an adapted energy regulatory landscape at a national and EU-wide level to meet EU phased energy reduction targets
Decarbonising fishery ports through smart cluster energy systems
The rising energy prices at seaports and fishing industries pose a major challenge because the pace of work and high demand for fish products has increased draāmatically. This comes at a time of growing international pressure and global motiāvations to address climate change and reduce carbon emissions in many different sectors of the economy.
In the literature review, a few research studies were found to highlight the opātimal use of power energy in ports, while some studies proposed certain measures that contribute to some extent to reducing energy consumption and carbon emisāsions. However, there is an absence of a study that discusses the possibility of deāveloping a holistic energy analysis and management that can be scaled from a site to a community level to achieve economically and environmentally viable benefits to the community.
The research study that is described in this thesis aims to develop a compreā hensive integrated system for the optimal use of energy in seaports through the deāvelopment of a smart grid system that is based on the renewable energy at Milford Haven Port, which was developed and used as an applied case stud. It is hoped that this study will contribute to reducing energy prices and that the port will achieve economic benefits by sharing its surplus power with the national grid.
A fiveāstage research methodology has been developed, starting with the proā cess of collecting and analysing data on fishery buildings, known as and energy audit. It then develops energy simulation models at the port using energy simulaātion software. The next stage aims to propose a smart grid model at multiālevels, namely a building, port and a community of 200 houses around a fishery port. The next stage consists of the development of two smart decisionāmaking systems: the first aimed at sharing surplus power with the neighbours of the port through a Peerto Peer (P2P) energy sharing approach; and the second aims to achieve financial inācomes for the port by selling surplus power to the national grid when energy prices rise, a priceābased control strategy is used in this system The model was developed and tested within 24 hours on randomly selected
days during the four seasons of the year. The simulation was characterised by the fact that it was carried out instantaneously to get an accurate result, which resemā bles a realālife system. In addition, the optimal number of energy storage systems was determined at multiālevels, which achieve the selfāsufficiency of the electric power that is needed to meet the energy demand during the day. Finally, a proposed road map has been developed to achieve nearly zero carbon fishery ports that can be applied to different ports in different locations
