Draycott et al.
The nascent wave energy sector has the potential to contribute significantly to global renewables targets, yet at present there are no proven commercially viable technologies. Macro-economic assessment is seldom used to assess wave energy projects, yet can provide insightful information on the wider economic benefits and can be used in conjunction with techno-economic analysis to inform policy…

The fundamental roadblock toward commercial-scale wave power operations is cost. The main objective of this work was to address the cost challenge facing wave energy commercialization through cost-sharing with pile breakwaters to be built for shore protection. This was achieved in this study through a dual-functional wave-power plant for generation of wave-power electricity and protection…

The power fluctuations produced by electric vehicles represent a drawback in large-scale residential applications. In addition to that, short power peaks could pose a risk to the stability of the electrical grid. For this reason, this study presents a feasibility analysis for a residential system composed of electric vehicle chargers. The objective is focused on smoothing the power…

The current work highlights development of novel thin-film composite hollow fiber membranes for pressure retarded osmosis applications to harvest salinity gradient energy. The membranes were developed with a specific target of harnessing the salinity gradient energy between wastewater reverse osmosis retentate and seawater reverse osmosis brine via osmotic mixing. The hollow fiber…

Cylindrical triboelectric nanogenerators (C-TENGs) have been designed for low frequency wave energy harvesting. However, the random, and low amplitude and frequency of the ocean waves represent a major challenge for the operation and performance of most C-TENGs. A C-TENG must be able to operate and be triggered by any wave conditions, even in the middle of the ocean, with uniform, low…

This paper seeks to identify promising sites and technologies, in Portugal, for co-located wave energy conversion and offshore aquaculture, whilst providing benchmark implementation references and guidelines to researchers. Accordingly, two case study sites are considered for deployment of five wave energy devices and up to six aquaculture species. A thorough analysis in terms…

According to the World Bank, the blue economy is the “sustainable use of ocean resources for economic growth, improved livelihoods, and jobs, while preserving the health of ocean ecosystem.”
Australia has the third largest Exclusive Economic Zone (EEZ) in the world, where 80% of the area is classified as offshore. The EEZ is a sea area for which a coastal state holds sovereign rights to…

India being a tropical country, has a large ocean thermal gradient available throughout the year that can be utilized to extract energy. This energy can be used to power a Low-temperature thermal desalination (LTTD) plant using the Ocean Thermal Energy Conversion (OTEC) method. OTEC works at a very low pressure, and developing a low-pressure turbine for OTEC is very challenging. The turbine…

Storm surge barriers across tidal inlets with navigation gates and tidal-flow gates to mitigate interior flood damage (when closed) and minimize ecological change (when open) are expensive. Daily high velocity tidal flows through the tidal-flow gate openings can drive hydraulic turbines to generate electricity. Money earned by tidal energy generation can be used to help pay for the high costs…

Worldwide increased demand for offshore renewable energy (ORE) industries and aquaculture requires developing efficient tools to optimize the use of the offshore space, reducing anthropic pressure. The synergetic development of marine renewable energy infrastructure with mariculture has been hypothesized as a way to reduce costs through shared infrastructure. In the Irish Sea, blue mussels (…

Ocean robots have important application value in both military and civil fields. However, ocean robots powered by batteries need to be launched and recovered frequently during mission due to the lack of continuous power supply. Capturing wave energy is a promising method to provide sustainable energy for ocean robots, despite that the existed wave energy converters (WECs) designed for ocean…

Most future emissions models predict that hundreds of billions of tons of carbon dioxide removal is needed by the end of the 21st century to complement emission reductions to meet the goals of the 2015 Paris Agreement. Macroalgae farming has been identified by several highly recognized organizations as a potential carbon capture strategy, and significant research investments have…

The capabilities of marine vehicles, such as autonomous underwater vehicles (AUVs) and remotely-operated vehicles (ROVs), have significantly advanced to perform complicated operations such as navigating through unexplored and dynamic environments, inspection of underwater structures, and monitoring of ocean conditions in deep waters. However, the limited energy resources of AUVs and tethered…

Finding new ways to enhance the production of kelp is useful for aquaculture and atmospheric carbon capture practices. Kelp aquaculture has significant potential to become a carbon-neutral source for biofuels. Upwelling, which increases kelp growth, is a process that draws cold, nutrient rich waters from deeper in the ocean towards the photic zone where kelp is grown. Waves provide an on-site…

In this presentation, I will discuss the numerical performance modeling of a small-scale (2 m diameter) point absorber wave energy converter (WEC) with inflation geometry control that expands the absorber’s water plane area. WECs of this size can be used for ocean observing, disaster relief, and autonomous underwater vehicle (AUV) charging, applications which could all benefit from a WEC with…

Wave energy converters (WECs) generate the necessary power to recharge an autonomous underwater vehicle (AUV) to enable a persistent and sustainable mission performance at remote locations. This research aims to develop a comprehensive framework for modeling the hydrodynamics of a WEC-AUV dock system, optimizing the AUV homing and docking trajectory, and predicting the power status of a…

The Makah Tribe is a Federally Recognized Tribe located in Neah Bay, WA. The Makah people maintain a unique connection to the sea and ocean resources. During the 1855 Treaty of Neah Bay negotiations, Caqawix (tsuh-ka-wihtl), a Makah Chief, famously told Euro-American settlers, “I want the sea. That is my country.” The Tribe's inherent sovereignty and management of marine spaces and resources…

Oysters are keystone species and ecosystem engineers that play many important roles in shoreline ecosystems. Oysters can serve these same roles even when farmed. Further, oysters could play an increasing role in a sustainable blue economy in coastal communities. In some farm operations, a process called oyster tumbling is used. Farmed oysters are put through a machine that rotates, removing…

The purpose of this project is to develop and validate an autonomous, robust, and self-contained micro-grid and power management system for deployment in remote communities or disaster relief situations that is capable of use with any renewable energy source. The Integrated Combined Energy (ICE) Box is capable of accepting “wild” AC or DC power from virtually any renewable energy source (wave…
