					</table><p>A Denmark-based firm, <a href="https://www.hyme.energy/" target="_blank" rel="noopener">Hyme Energy</a>, has developed a novel energy storage system that uses a type of salt known as sodium hydroxide, known to have exceptional heat storage capabilities and can withstand temperatures up to 1,292°F.</p>
<p>Hyme Energy&#8217;s storage system can store more energy by utilizing this high-temperature salt, making it more efficient than conventional systems.</p>
<p>Additionally, sodium hydroxide is cost-effective, improving the system&#8217;s overall efficiency.</p>
<p>The company said that when Hyme&#8217;s system uses heat instead of just generating electricity, it can achieve efficiencies exceeding 90%. It currently has its sights set on the industrial and residential markets that require heat.</p>
<p>Numerous potential storage solutions are being developed, including large-scale batteries and compressed air storage in underground vaults, all of which aim to ensure an uninterrupted electricity supply during low wind and solar power availability.</p>
<p>The team said this energy storage system could amass significant amounts of energy and hold it for up to 24 hours, surpassing the eight-hour discharge capability of lithium-ion storage systems.</p>
<p>Molten salt represents an alternative energy storage method, which involves heating the salts using excess energy from solar and wind sources and later utilizing the stored heat to power a turbine when there is an energy shortage.</p>
<p>Molten salt technology is already utilized in concentrated solar power systems.</p>
<p>However, a significant drawback of this method is that the most used salts, namely sodium nitrate and potassium nitrate, must reach a higher temperature, resulting in a low efficiency of approximately 70% for electricity delivery.</p>
<p><strong>Demonstration System</strong><strong> </strong></p>
<p>Hyme Energy is working on two demonstration facilities for its innovative energy storage system.</p>
<p>The first is a 1.5-MW storage unit in Esbjerg, which will be commissioned this year as an integration project to test components and system integration. The second, a larger 15-20 MWh facility, is planned for Denmark&#8217;s energy island, Bornholm, in 2024.</p>
<p>Hyme&#8217;s system uses two storage tanks and sodium hydroxide, a cost-effective and efficient salt. It will replace an oil boiler in a cogeneration plant, providing the district with steam, power, and heat.</p>
<p>Seaborg Technologies, Hyme&#8217;s sister company, has developed a corrosion control system that allows molten salt to be used in small modular nuclear reactors without causing damage.</p>
<p>If successful, this energy storage method could reduce reliance on fossil fuels and provide power during low wind and solar energy.</p>
<p>Researchers at the Fraunhofer Institute for Solar Energy Systems (ISE) have <a href="https://www.mercomindia.com/researchers-find-solar-pv-storage-systems" target="_blank" rel="noopener">developed</a> a solution that combines power from renewable sources with electricity from the public grid and uses batteries to compensate for fluctuations.</p>
<p>Earlier this month, researchers at the Shandong Academy of Medical Sciences, China, and Kyushu Institute of Technology, Japan, <a href="https://www.mercomindia.com/crab-shells-could-power-rechargeable-batteries" target="_blank" rel="noopener">claimed</a> to upcycle crab shells into porous, carbon-filled materials with various uses, including using the crab carbon to create anode materials for sodium-ion batteries.</p>

Engineers Harness Sodium Hydroxide for Sustainable Energy Storage

<p>United Kingdom-based <a href="https://www.sse.com/" target="_blank" rel="noopener noreferrer">SSE Enterprise</a> is working on a vehicle-to-grid (V2G) project at London’s Northumberland Park bus garage, where electricity would be generated from buses when it’s not ferrying passengers.</p>
<p>The ‘Bus2Grid’ garage will function as a ‘virtual power station’ using V2G technology and feed the energy stored in the vehicle’s battery back into the grid. The buses would be recharged when the demand is low, and power will be fed back to the grid when the demand peaks.</p>
<p>According to SSE, if all 9,000 buses plying on London’s streets are brought under the Bus2Grid project, then 150,000 homes could be powered.</p>
<p>The Bus2Grid project led by SSE Enterprise in partnership with Go-Ahead London, BYD, Leeds University, and U.K. Power Networks, will employ 28 state-of-the-art double-decker buses, capable of returning over 1 MW of energy to the grid in its trial run.</p>
<p>The three-year trial is funded by the Department for Business, Energy and Industrial Strategy (BEIS), and the Office for Low Emission Vehicles (OLEV) with the support of Innovate U.K.</p>
<p>SSE Enterprise claims to have electrified most of the electric-bus garages in London, wherein a bi-directional charging mechanism will return the energy stored in the batteries back to the grid. This Bus2Grid technique would explore both the commercial and social benefits of the energy and passenger transportation systems by developing services for the national grid, regional distribution network operators, bus operators, and transport authorities.</p>
<p>Meanwhile, in India, the <a href="http://pib.nic.in/newsite/pmreleases.aspx?mincode=53" target="_blank" rel="noopener noreferrer">Department of Heavy Industry</a> under the Ministry of Heavy Industry and Public Enterprises has <a href="https://mercomindia.com/electric-buses-deployed-indian-cities/" target="_blank" rel="noopener noreferrer">granted approval</a> for 5,595 electric buses to be deployed in 64 cities under the Faster Adoption and Manufacturing of Hybrid and Electric Vehicles (FAME-II) program.</p>
<p>In June 2019, the Department of Heavy Industry had invited <a href="https://mercomindia.com/government-seeks-proposals-from-states-for-5000-electric-buses/" target="_blank" rel="noopener noreferrer">expressions of interest</a> from state transport departments for the deployment of 5,000 electric buses under the FAME II program.</p>
