流体动力行业已经超越了最初的测试阶段，在全球范围内引入、建造和测试了全面的项目。然而，在取得商业成功之前，仍然需要注意降低这些系统的成本、优化单个系统和阵列以及平衡能源提取与环境影响等主要障碍。本研究探讨了近零水头流体动力技术的进步和局限性，以及在考虑设计、实施和操作阶段的强化技术时，提高潜力和适用性的可能性。它的目标有三个：审查小规模最先进的接近于零的hydrokinetic-current-energy-conversion-technologies，，以评估障碍，包括知识、信息和数据方面的差距，以及评估水基础设施所有者和运营商的时间和资源限制。一个案例研究总结了南非第一个永久性现代流体动力装置的设计和实施情况，在每个设计和运行阶段，通过优化提高了产出。一项经济分析证实了具有竞争力的均衡化能源成本，并进一步强调了现有水利基础设施相对未开发的广阔潜力。
The hydrokinetic industry has advanced beyond its initial testing phase with full-scale projects being introduced, constructed and tested globally. However primary hurdles such as reducing the cost of these systems, optimizing individual systems and arrays and balancing energy extraction with environmental impact still requires attention prior to achieving commercial success. The present study addresses the advances and limitations of near-zero head hydrokinetic technologies and the possibility of increased potential and applicability when enhancement techniques within the design, implementation and operational phases are considered. Its goal is threefold: to review small-scale state-of-the-art near-zero hydrokinetic-current-energy-conversion-technologies, to assess barriers including gaps in knowledge, information and data as well as assess time and resource limitations of water-infrastructure owners and operators. A case study summarizes the design and implementation of the first permanent modern hydrokinetic installation in South Africa where improved outputs were achieved through optimization during each design and operation phase. An economic analysis validates a competitive levelized cost of energy and further emphasizes the broad potential that is relatively unexplored within existing water-infrastructure.
