					</table><p>Researchers at the Indian Institute of Technology (<a href="https://www.iitm.ac.in/" target="_blank" rel="noopener">IIT Madras</a>) have said that all-organic redox flow batteries (NORFBs) could achieve enhanced energy density, stability, and solubility by introducing pyrylium salt into the mix.</p>
<p>This development could pave the way for cleaner and more efficient grid energy storage systems.</p>
<p>The team’s research focuses on non-aqueous all-organic redox flow batteries (NORFBs), which have gained significant interest due to their environmental friendliness and higher energy density than aqueous batteries.</p>
<p>The prototype NORFB developed by the researchers exhibited promising results, operating at a high current density of 40 mA cm-2.</p>
<p>It also demonstrated stability with 60 stable galvanostatic charge-discharge (GCD) cycles and an average coulombic efficiency of 97%.</p>
<p>The key component of a redox flow battery is the redox-active organic molecule (ROM), which stores and releases energy.</p>
<p>However, conventional ROMs often have limitations such as low solubility and poor mass and charge transfer kinetics, leading to low current and energy densities.</p>
<p>To address these challenges, the researchers introduced the use of pyrylium salt in NORFBs for the first time.</p>
<p>Pyrylium salts are widely employed in synthetic organic chemistry as photocatalysts and precursors for various applications. By utilizing two different chemical components – 2,4,6-triphenylpyrylium tetrafluoroborate (TPT), as the anolyte and N-decyl phenothiazine (DPTZ) as the catholyte, the researchers constructed the NORFB.</p>
<p>The study demonstrated that TPT offers high solubility, reversibility, and improved stability, which are crucial factors for achieving high energy density and cyclability in redox flow batteries.</p>
<p>The researchers also noted that the 2nd, 4th, and 6th positions of pyrylium salt provide a versatile platform for tailoring the electrochemical activity and stability of the ROMs.</p>
<p>Ragupathy, an associate professor and principal scientist at the Redox Flow Battery Research Group, <a href="https://cecri.res.in/Default.aspx" target="_blank" rel="noopener">CSIR</a>-Central Electrochemical Research Institute, emphasized that the use of non-aqueous solvents with a wider electrochemical potential window, along with low-cost and abundant redox-active organic materials, makes NORFBs an attractive option for grid energy storage applications.</p>
<p>The successful implementation of TPT as the anolyte also highlights its solubility, reversibility, and improved stability, which are crucial for achieving high energy density and cyclability in redox flow batteries.</p>
<p>Furthermore, the study showed that by modifying substituents at different positions of pyrylium salts, it is possible to fine-tune the redox behavior and stability of ROMs, providing a versatile platform for further exploration in this field.</p>
<p>Last year, researchers at the Chinese Academy of Sciences (CAS) <a href="https://mercomindia.com/researchers-claim-aqueous-redox-flow-battery-for-renewable-storage/" target="_blank" rel="noopener">claimed</a> to have built a stable kilowatt-scale aqueous redox flow battery with high-performance organic redox-active molecules for renewable storage.</p>
<p>In the same month, researchers at the University of Sydney <a href="https://mercomindia.com/researchers-claim-sodium-sulfur-battery-potent-than-lithium-ion/" target="_blank" rel="noopener">claimed</a> to have developed a new, low-cost sodium-sulfur battery with four times the energy capacity of lithium-ion batteries.</p>

					</table><p>Researchers at <a href="https://www.iitm.ac.in/" target="_blank" rel="noopener">IIT Madras</a> claimed to have developed an energy converter that can generate electricity from sea waves. Trials were completed successfully in the second week of November.</p>
<p>The test was conducted in partnership with an Andhra Pradesh-based startup Virya Paramita Energy (<a href="https://www.viryaparamita.co.in/" target="_blank" rel="noopener">VPE</a>), and Motilal Nehru National Institute of Technology (<a href="http://www.mnnit.ac.in/" target="_blank" rel="noopener">MNNIT</a>) Allahabad.</p>
<p>IIT Madras and VPE have an agreement to commercialize the technology.</p>
<p>The energy converter system, dubbed Sindhuja-I, meaning  &#8216;generated from the ocean,&#8217; was deployed about six kilometers from the coast of Tuticorin in Tamil Nadu, at 20 meters depth in the sea.</p>
<p>Waterfront Engineering and Infrastructure assisted in deploying the system, which aims to produce 1 MW of power from ocean waves in the next three years.</p>
<p>The device will aim to provide reliable electricity and communication in remote offshore locations.</p>
<p>Highlighting the impact of this project, lead author Abdus Samad, Department of Ocean Engineering, IIT Madras, said, “India has a 7,500 km long coastline capable of producing 54 GW of power, satisfying a substantial amount of the country&#8217;s energy requirement. Seawater stores tidal, wave, and ocean thermal energy. Among them, the harnessing of 40 GW wave energy is possible in India.”</p>
<p>“The vision is to make India sustainable by tapping the marine energy and net zero carbon emission to mitigate climate impact,&#8221; he added.</p>
<p>The electrical storage system for the device was designed by the <a href="https://www.gkciet.ac.in/" target="_blank" rel="noopener">GKC Institute of Engineering and Technology</a> and <a href="https://www.mckvie.edu.in/" target="_blank" rel="noopener">MCKV Institute of Engineering</a>, West Bengal.</p>
<p>The researcher said that a single device at different locations along the Indian coastline could generate large quantities of clean power.</p>
<p>Currently, the team is considering placing multiple devices in an array configuration for maximum wave power extraction from the location.</p>
<p><strong><img loading="lazy" decoding="async" class="aligncenter wp-image-45962 size-full" src="https://mercomindia.com/wp-content/uploads/2022/12/pressrelease05_12_2022_12_08.jpg" alt="" width="571" height="428" srcset="https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2022/12/pressrelease05_12_2022_12_08.jpg 571w, https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2022/12/pressrelease05_12_2022_12_08-300x225.jpg 300w" sizes="(max-width: 571px) 100vw, 571px" /></strong></p>
<p><strong>How Does it Work</strong></p>
<p>The generator has three main elements: a floating buoy, a spar, and an electrical module.</p>
<p>The buoy moves up and down as the wave hits. In the present design, a balloon-like system called a &#8216;buoy&#8217; has a central hole that allows a long rod or the spar to pass through it. The spar floats while a mooring chain keeps the system in place.</p>
<p>The spar can be fixed to the seabed and is not affected by passing waves, while the buoy moves up and down to produce relative motion between them. The relative motion results in rotation within the electric generator to produce power.</p>
<p>The team said the success of the project could fulfill the U.N. Ocean Decade and Sustainable Development Goals and India&#8217;s goals, including deep water missions.</p>
<p>It can advance clean energy initiatives, achieve a blue economy, and help the country meet its climate goals of generating 500 GW of electricity by 2030 through renewable energy.</p>
<p>The project was jointly funded through the Innovative Research Project Program of IIT Madras and the Australian Alumni Grant Program 2022 by the Department of Foreign Affairs and Trade, Australian Government.</p>
<p>It was also partly funded by the <a href="http://tbi-kiet.in/" target="_blank" rel="noopener">TBI-KIET</a> under the Department of Science and Technology Nidhi-Prayas program.</p>
<p>Currently, the lab is also researching other applications for this technology, such as producing power for smaller devices for the ocean, navigational buoys, and data buoys.</p>
<p>In October, Ashok Leyland and researchers of IIT Madras National Centre for Combustion Research and Development (NCCRD) <a href="https://www.ashokleyland.com/in/en/customers/press-release/ashok-leyland-and-iit-madras-researchers-join-forces-to-develop-hybrid-electrical-vehicles-using-turbine-technology" target="_blank" rel="noopener">partnered</a> to develop hybrid electric vehicles (EVs) using turbine technology.</p>
<p>Researchers at IIT Mandi recently <a href="https://mercomindia.com/iit-mandi-researchers-claim-eco-friendly-method-to-recycle-wind-turbines/" target="_blank" rel="noopener">claimed</a> to have successfully used microwaves to recycle polymer composites from old wind turbine blades, using a rapid, sustainable, and comparatively eco-friendly method.</p>

Daily News Wrap-Up: Ashok Leyland and IIT Madras to Develop Hybrid EVs

<p>Hitachi ABB Power Grids has signed a memorandum of understanding  (MoU) with Ashok Leyland and the Indian Institute of Technology Madras (IITM) for an e-mobility pilot project.</p>
<p>Under the tripartite agreement, the trio will run an electric bus (e-bus) pilot to support sustainable in-campus commuting by <a href="https://www.iitm.ac.in/" target="_blank" rel="noopener noreferrer">IITM</a>&#8216;s students and staff. The e-bus will be provided by <a href="https://www.ashokleyland.com/en/web/ashokleyland/home" target="_blank" rel="noopener noreferrer">Ashok Leyland</a>, incorporating <a href="https://www.hitachiabb-powergrids.com/in/en" target="_blank" rel="noopener noreferrer">Hitachi ABB Power Grids</a>&#8216; flash-charging technology – Grid-eMotionTM Flash.</p>
<p>IITM will host the infrastructure required to operate the flash-charging system for the e-bus. Recently, the IITM had also developed an <a href="https://www.iitm.ac.in/happenings/press-releases-and-coverages/iit-madras-develops-autonomous-solar-vehicle-survey-water" target="_blank" rel="noopener noreferrer">autonomous solar vehicle</a> to survey water-bodies and provide real-time data.</p>
<p>According to the press statement, smart e-mobility is at a nascent stage in India. The switch to electric vehicles had previously presented challenges for bus operators because it is difficult for battery-operated buses to maximize passenger load carrying capacity and running time while making the whole operation economically viable. An e-bus with flash-charging technology can solve that problem while improving the quality of air by reducing pollution in densely populated urban areas.</p>
<p>In January this year, Ashok Leyland <a href="https://mercomindia.com/ashok-leyland-abb-power-grids-fast-charging-electric-buses/" target="_blank" rel="noopener noreferrer">partnered</a> with ABB Power Grids to develop fast charging for electric buses.</p>
<p>&#8220;We need to have all hands-on deck – industry, academia, and policymakers to develop a strong and reliable local ecosystem to support the Indian electric vehicle (EV) revolution. We are delighted to be partnering with Ashok Leyland and IITM to provide a zero-emissions mass public transportation bus system through our award-winning technology, localized for the Indian market,&#8221; said N Venu, managing director, Hitachi ABB Power Grids in India.</p>
<p>&#8220;This latest alliance will further help us stay at the forefront of embedding innovative and indigenous technologies to nurture the smart e-mobility ecosystem in India,&#8221; said Dr. N Saravanan, chief technology officer, Ashok Leyland.</p>
<p>&#8220;We hope to study and understand how the right technology can enable an efficient transport system without damaging the environment. We are delighted to have partnered with the best in the industry for this endeavor,&#8221; said Professor Bhaskar Ramamurthi, Director, IIT Madras.</p>
<p>Last year, the Ministry of Science &amp; Technology <a href="https://mercomindia.com/ministry-of-science-solar-harnessing-center-iit-madras/" target="_blank" rel="noopener noreferrer">set up</a> a solar energy harnessing center at the Indian Institute of Technology, Madras.</p>
<p>Several IITs across the country are taking exemplary steps to promote sustainability on their campuses. Previously, to encourage smart mobility, the Indian Institute of Technology Patna <a href="https://mercomindia.com/iit-e-cycle-patna-campus/" target="_blank" rel="noopener noreferrer">floated</a> an expression of interest for providing electric cycles on a use and pay basis for the staff and students at the university campus.</p>
<p>Ashok Leyland also announced that Optare  Group, its majority-owned UK subsidiary is renamed Switch Mobility as part of its drive towards electrification and new mobility services. Switch (Optare) is a leading player in electric buses with more than 150 of them currently operating in its home market. It has <a href="https://mercomindia.com/ashok-leyland-subsidiary-31-ev-buses-london/" target="_blank" rel="noopener noreferrer">delivered</a> 30 Electric Double Decker buses to Metroline in London. The company is currently fulfilling orders for operators including Tower Transit, London, and First York.</p>
