PhD student Rebecca McCabe takes part in the 2021 MIT Energy Hackathon
PhD student Rebecca McCabe traveled to Boston to participate in the MIT Energy Hackathon. This weekend-long intensive event connects students from diverse academic backgrounds with industry partners to solve problems critical to emissions reduction. Rebecca’s team, Good Vibes Energy, tackled the Chevron-sponsored challenge of ocean-based CO2 sequestration. The team investigated various chemical and biological mechanisms for marine carbon capture and presented a synthesized portfolio recommendation to Chevron, accounting for technology readiness, deployment feasibility, and environmental risks.

Research presented at OCEANS’21 Conference
Some of the latest results on the design and testing of the control system for Platform for Expanding AUV exploRation to Longer ranges (PEARL), an integrated autonomous floating servicing station that utilizes renewable energy to simultaneously provide AUV battery recharging and data uplink via new generation high-bandwidth low-Earth orbit satellite constellations, were presented at the OCEANS’21 conference. The paper titled ‘Autonomous Control of a Prototype Solar-powered Offshore AUV Servicing Platform’ is available for discussed the implementation of a low- cost autonomous control system consisting of off-the-shelf hardware components, built around an embedded Raspberry Pi microcomputer and Arduino microcontroller. The open-source MOOS-IvP marine robotics software was used to achieve autonomous operations, consisting of station-keeping and waypoint missions. You can download the paper from the conference website.

Research presented at the MIT A + B Applied Energy Symposium
Prof. Haji presented work on the ‘Optimization of a symbiotic wind-wave-storage farm for cost and load matching’ at the 2021 MIT A + B Applied Energy Symposium. Her presentation discussed how wave energy converters coupled with offshore wind turbines could not only reduce fatigue stress on the overall structure, but also could reduce the need for energy storage for offshore farms, ultimately lowering costs. In this work, it was shown that as renewable energy penetration levels increase, the optimal storage energy capacity required to minimize curtailed power increases on the order of 5 hours, 40 hours, and 150 hours for renewable energy penetration levels of 50%, 75%, and 100% respectively. View a recording of her presentation.

Ezra’s Round Table Systems Seminar on Mineral Extraction
Prof. Haji presented some of the ongoing work in the SEA Lab on designing symbiotic systems for passive seawater mineral extraction at the Ezra’s Round Table Systems Seminar. This presentation discussed how chemical adsorbents can be used to passively extract minerals from seawater. Symbiotic systems that integrate a mineral harvester with an existing offshore wind turbine have been shown to increase efficiency, reduce environmental impact, and decrease mineral production cost. This talk described the foregoing, and also present some promising initial work applying these design tools to minerals that are key to large-scale lithium-ion battery production, such as cobalt and lithium. The talk was recorded and is available to watch on the Cornell Systems Engineering YouTube page.

Research presented at the MIT A + B Applied Energy Symposium
Prof. Haji presents work on the ‘Analysis of Integrated Pumped Hydro Reverse Osmosis Systems for Iran (IPHROSI) at the 2020 MIT A + B Applied Energy Symposium. Her presentation discussed how IPHROSI could enable Iran to meet both its energy and freshwater needs through renewable and sustainable technologies. A number of regions throughout Iran were highlighted for their suitability for the development of IPHROSI, finding there existed the potential to store over 25 TWh of renewable energy, more than all of the country’s electricity generation from oil in 2018 (23 TWh). These sites could supply both energy and freshwater to meet the needs of over 500 million people (over five times the projected population of Iran in 2050). View a recording of her presentation.

Presentation at Ocean Sciences Meeting 2020
Prof. Haji presented recent work on ‘A Framework for the Design of Renewably Powered Offshore AUV Servicing Platforms‘ at the Ocean Sciences Meeting 2020, held in San Diego, CA. The talk detailed a framework for the co-optimization of the design and operation of underwater, surface, and space assets, which enable PEARL to overcome some of the past limitations in AUV servicing platforms. The co-design framework presented included systems for on-board renewable energy generation and satellite data transfer, and can be modified to servicing platforms using ocean renewable energy such as power from waves, tides, currents, or winds. Platforms like PEARL could enable AUVs to provide increased and reliable scientific data key to the sustainable growth of the Nation’s Blue Economy.
