With the intensification of environmental pollution and energy crises, people have increasingly emphasized the development and utilization of renewable energy. The ocean, as one of the regions with the richest resources on Earth, is also abundant in energy resources. Ocean tidal energy, as a high-quality renewable energy, has attracted significant attention. Its working principle is to convert the kinetic energy of seawater into electrical energy during the ebb and flow of tides. However, due to limitations in tidal energy technology and costs, its commercial development still faces challenges. The purpose of this article is to further promote the commercial development of tidal energy. The paper reviews the economic methods for evaluating ocean tidal energy, analyzes the economic benefits of tidal energy commercialization, and looks back at different tidal energy technologies at the present stage as well as the prospects for these technologies. The author employs an economic cost assessment model, taking into account various cost factors of tidal power generation, such as construction costs, maintenance costs, repair costs, and operating costs. By comparing the costs, the author deduces the advantages and disadvantages of different technologies and further analyzes their feasibility. Based on these analytical discussions, the article provides relevant development suggestions. To a certain extent, this article offers reference significance for policymakers, investors, and related enterprises.
随着环境污染和能源危机的加剧，人们越来越重视可再生能源的开发和利用。海洋作为地球上资源最丰富的区域之一，其能源资源也十分丰富。海洋潮汐能作为一种优质的可再生能源，已引起广泛关注。其工作原理是在潮汐的涨落过程中将海水的动能转化为电能。然而，由于潮汐能技术和成本的限制，其商业开发仍面临挑战。本文旨在进一步推动潮汐能的商业开发。文章回顾了评估海洋潮汐能的经济方法，分析了潮汐能商业化的经济效益，并回顾了现阶段不同的潮汐能技术以及这些技术的前景。作者采用经济成本评估模型，考虑了潮汐发电的各种成本因素，如建设成本、维护成本、维修成本和运营成本。通过比较成本，作者推断出不同技术的优缺点，并进一步分析其可行性。基于这些分析讨论，文章提出了相关的发展建议。本文在一定程度上为政策制定者、投资者和相关企业提供了参考意义。
