Purpose Oceans offer a vast amount of renewable energy. Tidal and wave energy devices are currently the most advanced conduits of ocean energy. To date, only a few life cycle assessments for ocean energy have been carried out for ocean energy. This study analyses ocean energy devices, including all technologies currently being proposed, in order to gain a better understanding of their environmental impacts and explore how they can contribute to a more sustainable energy supply. Methods The study followed the methodology of life cycle assessment including all life cycle steps from cradle to grave. The various types of device were assessed, on the basis of a functional unit of 1 kWh of electricity delivered to the grid. The impact categories investigated were based on the ILCD recommendations. The life cycle models were set up using detailed technical information on the components and structure of around 180 ocean energy devices from an in-house database.Results and discussion The design of ocean energy devices still varies considerably, and their weight ranges from 190 to 1270 t, depending on device type. Environmental impacts are closely linked to material inputs and are caused mainly by mooring and foundations and structural components, while impacts from assembly, installation and use are insignificant for all device types. Total greenhouse gas emissions of ocean energy devices range from about 15 to 105 g CO 2 -eq. kWh −1 . Average global warming potential for all device types is 53 ± 29 g CO 2 -eq. kWh −1 . The results of this study are comparable with those of other studies and confirm that the environmental impacts of ocean energy devices are comparable with those of other renewable technologies and can contribute to a more sustainable energy supply. Conclusions Ocean energy devices are still at an early stage of development compared with other renewable energy technologies. Their environmental impacts can be further reduced by technology improvements already being pursued by developers (e.g. increased efficiency and reliability). Future life cycle assessment studies should assess whole ocean energy arrays or ocean energy farms.

“…wave energy, which theoretical potential in Africa is estimated at 3,500 TWh/year), however for now almost all of the technologies available to harness them are still at a conceptual phase of development and the global capacity installed today is negligible (Lewis et al 2011). The only exception is tidal energy, which can be harnessed by underwater turbines and indeed one such project has been recently proposed in Ghana (CNN 2017).…”

Energy in Africa Challenges and Opportunities SpringerBriefs in EnergySpringerBriefs in Energy presents concise summaries of cutting-edge research and practical applications in all aspects of Energy. Featuring compact volumes of 50-125 pages, the series covers a range of content from professional to academic. Typical topics might include:• A snapshot of a hot or emerging topic • A contextual literature review • A timely report of state-of-the art analytical techniques • An in-depth case study • A presentation of core concepts that students must understand in order to make independent contributions.Briefs allow authors to present their ideas and readers to absorb them with minimal time investment. Briefs will be published as part of Springer's eBook collection, with millions of users worldwide. In addition, Briefs will be available for individual print and electronic purchase. Briefs are characterized by fast, global electronic dissemination, standard publishing contracts, easy-to-use manuscript preparation and formatting guidelines, and expedited production schedules. We aim for publication 8-12 weeks after acceptance.Both solicited and unsolicited manuscripts are considered for publication in this series. Briefs can also arise from the scale up of a planned chapter.

“…Ocean Renewable Energy (ORE) tersebut sampai saat ini masih bersifat konseptual atau masih berada pada tahap penelitian awal (preliminary assessesment). Sumber energi yang tersebar di seluruh dunia secara merata dan sifatnya yang bisa diprediksi melalui proses modelling dan hindcasting dan mempunyai densitas energi yang tinggi membuat ORE mempunyai potensi yang sangat tinggi untuk memberi efek positif dan menjadi sumber energi utama dunia pada masa mendatang (Lewis, 2011).…”

Abstrak. Energi gelombang air laut adalah salah satu jenis ocean renewable energy (ORE) yang menjadi salah satu potensi kemaritiman dari Indonesia. Energi tersebut mempunyai beberapa keunggulan bila dibandingkan dengan energi fosil (minyak dan gas bumi) dan menjadi salah satu jenis energi terbarukan yang banyak diteliti dan dikembangkan oleh peneliti dari seluruh dunia. Salah satu upaya memetakan potensi energi gelombang laut adalah dengan menghitung tinggi gelombang air laut tersebut menggunakan berbagai metode pengamatan, salah satunya adalah Synthetic Aperture Radar (SAR). SAR adalah salah satu jenis sensor penginderaan jauh yang sedang berkembang dimana dapat memonitor dan memetakan tinggi gelombang air laut secara cepat dan efektif. Dalam penelitian ini, sebuah citra SAR diolah untuk mendapatkan tinggi gelombang di perairan Pulau Poteran, Madura.
