Four pilot projects to reduce greenhouse gasemissions in ports in Africa and the Caribbean are ready for implementation, following their selection under the IMO CARESGlobal Technology Challenge.
According to the International Maritime Organization (IMO), the selected technology proposals cover renewable energy production in ports and port call data sharing for “Just-in-Time” shipping. They reflect a strong potential for scalability and replicability across different regions and operational contexts. They will be implemented in Mauritius, St. Kitts and Nevis, Namibia, and Trinidad and Tobago, as part of the IMO-implemented and EU-funded Global Maritime Technology Centre Network (GMN) Phase II Project.
By working closely with local stakeholders, the proposals are tailored to address specific challenges in each region while contributing to global efforts to reduce greenhouse gas (GHG) emissions. The implementation phase will offer valuable insights into how these solutions can be expanded to other ports and countries.
Clean Marine Shipping (CMS) developed a technical proposal for GHG reduction in maritime operations at the port of Port Louis with Circular Bio-derived Fuels and Hydrogen Technologies (BioH2Energy). Integrating CMS BioH2Energy technology at Port Louis, Mauritius, the technology demonstration will convert organic waste into energy.
The project proposes to build a 2.4 MW system converting two tonnes of organic waste to supply 100 KW per hour. The project aims to decrease the current electricity grid consumption from thermal sources (807 gCO2e/KWh) at the Port of Port Louis to a more sustainable option of -0.045 gCO2e/KWh. Additionally, it intends to reduce 482 t CO2e/year by using organic waste as fuel for the BioH2Energy system instead of landfilling it.
The SYG TECH proposal aims to decarbonize port operations using renewable energy-powered microgrids. The technology encompasses a Vertical Axis Wind Turbine incorporating a novel and effective “storm protection” feature.
SYG TECH developed a technical proposal to build a renewable-powered microgrid integrating its wind turbine at the Basseterre Deep Water port, St. Kitts and Nevis, where renewable wind energy will cut approximately 46% of the port’s GHG emissions. The successful installation and operation should result in an annual saving of 141 tonnes of CO2eq. The feasibility study suggested that a proper mixture of wind, solar, and storage would make the port microgrid 100% carbon neutral.
Given that St. Kitts and Nevis are in a hurricane-prone area, the wind turbine will incorporate a tilt-down feature. The SYG TECH turbine is a smart device that controls its wings by monitoring wind speed. When the wind speed reaches the designated cut-off wind velocity level, it is expected to close its wings, bringing the turbine into the “storm protection” formation.
BM Bergmann Marine GmbH and Marine Fields Holding Ltd developed a proposal to implement a solution based on the port call data sharing platform PERSEUS in a Software-as-a-Service (SaaS) concept.
The project proposes to customise the PERSEUS data sharing platform to allow all actors in the port and the port State authorities to gain direct access to port call data, which is the prerequisite for implementing “Just-In-Time” operations and automated reporting. The PERSEUS system will enable the port to reduce Total Turnaround Time, improve port facility utilization, and reduce associated GHG emissions.
The technology is selected by Port of Walvis Bay and Port of Lüderitz, Namibia and Port of Point Lisas, Trinidad and Tobago. The implementation of technology aims to achieve an overall reduction of 10% GHG emission within one year.
The initiative aimed to identify innovative, technology-neutral solutions that accelerate decarbonization in shipping and ports in Africa and the Caribbean. Following an extensive review process that included input from government representatives, academia, and industry associations, four technology proposals were selected from a pool of 21 entries. Entries spanned the technology spectrum, ranging from wind turbines and kites; carbon capture, artificial intelligence and data sharing systems; to hull coatings and fuel emulsifiers.
Under the EU-funded GMN Phase II Project, the proposals will be implemented in the beneficiary countries. These technology demonstration projects will assist developing countries, especially the least developed countries (LDCs) and small island developing states (SIDS), in meeting the IMO’s energy efficiency and greenhouse gas reduction targets.
Dan Ton is Program Manager of Smart Grid R&D within the U.S. Department of Energy''s (DOE) Office of Electricity(OE).He is responsible for developing and implementing a multi-year R&D program plan for next-generation smart grid technologies to transform the electric grid in the United States, through public/private partnerships.
He has served as Acting Deputy Assistant Secretary of OE''s Power Systems Engineering Division - now known as the Advanced Grid R&D Division that capacity, he was responsible for managing the development of projects for "next generation" electricity delivery technologies and supporting activities to accelerate their introduction to the marketplace.Key activities in theDivision focused on smart grid research and development, energy storage, and cybersecurity for energy delivery systems, all in support of the OE''s mission to drive electric grid modernization and resiliency.
The U.S. has pledged to achieve net-zero greenhouse gas emissions by 2050. Port electrification will play a major role in accomplishing this. Port electrification is challenging because of ports'' sizes, complexity, and resource mix, necessitating approaches that can address specific port''s needs and can apply to all ports as essential hubs for transportation and the exchange of goods.
The Pacific Northwest National Laboratory (PNNL) released the Port Electrification Handbook, a resource to aid the transition to cleaner energy sources, including electricity, to power electricity of maritime and commercial ports. The handbook effort was supported by the U.S. Department of Energy Office of Electricity''s (OE''s) Microgrid Research and Development (MGRD) program.
By 2035, microgrids are envisioned to be essential building blocks of the future electricity delivery system to support resilience, decarbonization, and affordability.
A microgrid is a group of distributed energy resources (DERs) and loads within a grid that can be separated from the grid and can act independently. They can also be reinserted into the larger grid system if necessary. They are especially helpful in serving remote or isolated communities. Because of their use of cleaner and/or renewable energy resources, microgrids they are well-suited for electrification applications of ports to meet their emissions reduction targets.
The Port Electrification Handbook delves into the many benefits of using microgrids for port electrification. Because they can be isolated from larger grids, they can be used as backup systems in case of power failures. They can play a pivotal role in improving resilience and the operation of critical infrastructure. They can help alleviate bottlenecks in power supply, reducing the need for fossil fuels and contributing to improved air quality. They can also be networked, or combined, to provide enhanced resilience and energy efficiency.
The Port Electrification Handbook is a significant step towards the International Maritime Organization''s ambition for ports to achieve net-zero emissions by or around 2050. The electrification of ports also assists port-adjacent communities and people who are the most impacted by the use of diesel, natural gas, or oil. Electrifying ports will play a significant role in improving these communities'' living conditions. OE is proud to be part of this and similar projects that promote growth and well-being.
