Smart Shore Power system with energy storage for self-discharging commercial vessels supporting Whole Vessel Efficiency

英国现有的大多数海上电力供应/充电基础设施要么规模相对较小，要么专注于满足电力消费者的需求，以按需供应为基础，直接从英国配电网络获取相对稳定的负荷。上述类型的供应的主要目标是满足立即脱碳的目标；与停泊船舶电力输送的相关成本和可持续性方面相比，如果考虑到这些问题，可能会被认为是次要问题。全球（国际海事组织）、地区（欧盟）和国家（英国）层面即将出台的一些新兴海事立法的总体方向表明，随着时间的推移，大多数400吨或以上的商业货船将被要求采取一种或另一种形式的脱碳措施。总的来说，基于当前或最近出现的技术，由于空间限制、相对成本收入比和操作方面的限制，随着船舶尺寸的减小，脱碳难度也会增加。该项目的目标是进行一项研究，以确定以实际、环境和经济上可持续的方式发展岸上储存和释放电能解决方案的可行性；能够满足商业货船运行的波动电力负荷需求，除了船舶基载外，船上自卸货物设备在长时间货物运行过程中经常产生高峰瞬态电力负荷。除了提供船舶运行所需的大量和波动的电力负荷的技术挑战外，该研究还将解决以下相关问题：(i)为了满足潮汐限制船舶运行的需求，可以向船舶提供与英国普遍存在的按需供电充电结构分离的电源；（ii）为船舶提供可持续来源的电力来源，以确保实现上游脱碳和船舶排放法规合规目标。该研究将进一步考虑通过单一岸上基础设施设施满足多艘船舶需求的相关方面，从而在一定程度上避免在多艘船舶上复制类似的脱碳技术；与此同时，减少了船舶运营商的材料使用和成本。最后，作为主要目标的补充，该项目将探索在船舶运行不需要可用储能时，英国电网供电到电网支持的潜力。

The majority of currently existing maritime electrical supply/charging infrastructure in the UK is either relatively small scale and/or focused on meeting the needs of electrical consumers drawing relatively stable loads directly from the UK electrical distribution network, on a supply-on-demand basis. The primary objective of the above type of supply is to satisfy an immediate decarbonisation objective; with the related cost and sustainability aspects of electrical power delivery to ships at berth, if they are considered, potentially deemed to be of secondary concern.The general direction of travel of a number of emerging strands of forthcoming maritime legislation at a global (IMO), regional (EU) and national (UK) level, suggests that over time, the majority of commercial cargo vessels of 400gt or more will be required to adopt decarbonisation measures of one form or another. In general terms, based on current or recently emerging technology, due to space constraints, the relative cost to revenue ratios and operational aspects, decarbonisation increases in difficulty as vessel size decreases.The objective of this project is to undertake a study to determine the feasibility of developing, in a practical, environmentally and economically sustainable manner, a shore-based store and release electrical energy solution; capable of meeting the fluctuating electrical load demands of commercial cargo vessels operating, in addition to vessel base loads, ship-mounted self-discharging cargo equipment drawing frequent high peak transient electrical loads throughout extended duration cargo operations.Additional to the technical challenges of delivering the significant and fluctuating electrical loads necessary for ship operations, the study will address the related issues of ensuring that: (i) to meet the needs of tidally constrained ship operations, an electrical power source can be provided to vessels decoupled from the supply on-demand electricity charging structure prevalent in the UK; and (ii), that an electrical power source is available to vessels from sustainable origins to ensure that both upstream decarbonisation and ship emission regulatory compliance objectives are achieved.The study will further consider the related aspect of serving the needs of multiple vessels from a single shore-based infrastructure installation, thereby, to a degree, avoiding replication of similar decarbonisation technology in multiple vessels; with the associated reduction in materials usage and cost for ship operators. Finally, as an adjunct to the primary objectives, the project will explore the potential for supply-to-grid support for the UK electrical network when available stored energy is not required for ship operations.
