In the recent interaction with M R Yuvatha, Senior Correspondent, siliconindia, Amlan Kanti Das shared his insights on The Role of Energy Storage in Sustainable Living.

Energy storage solutions (ESS) play a crucial role in controlling greenhouse gas emissions. By efficiently storing energy generated from intermittent renewable sources such as solar and wind, ESS can reduce power variability while simultaneously decreasing fossil fuel consumption. Companies like Luminous Power Technologies play a pivotal role in reducing greenhouse gas emissions by advancing sustainable energy storage solutions that harness solar power. Their comprehensive portfolios, which include off-grid, hybrid, and Grid-Tie Inverter (GTI) solar systems, align directly with India's renewable energy goal of achieving 500 GW by 2030. Central to their eco-conscious business models, these systems efficiently store solar energy, ensuring a reliable power supply while decreasing reliance on fossil fuels.

Over the past three years, these companies have recorded 13.28 GWh of renewable energy consumption and a reduction of 9.79K tons in CO2 emissions through green energy generation. This substantial impact underscores their commitment to India's net-zero objectives and highlights the critical role of sustainable ESS in mitigating environmental degradation.

Reducing e-waste and promoting sustainable manufacturing practices is a key priority for companies in the sector.



Decentralized Energy and Sustainable Storage Solutions

With the increasing demand for energy independence, decentralized energy systems, such as microgrids and localized storage solutions, are on the rise. Some of the companies in this sector focus on developing innovative, scalable, and reliable backup solutions tailored to the evolving needs of homes and enterprises. These solutions have provided widespread support across 750 districts in India, particularly benefiting areas with unreliable grid infrastructure.

By optimizing renewable energy use, these systems reduce transmission losses while ensuring energy stability and reliability close to the point of use. Solar solutions, including off-grid and hybrid systems, are central to this decentralized approach. When integrated with energy storage, these systems guarantee a continuous power supply even during periods without sunlight, effectively balancing energy supply and demand. This maximizes the use of renewable energy, supports India's net-zero goals, and reduces reliance on conventional power sources, thus minimizing carbon emissions.

Energy storage technologies act as a buffer between supply and demand, ensuring stable and reliable power during peak usage times. Some of the companies like luminous in the sector use ESS to effectively store excess energy generated during low-demand periods, typically when renewable sources like solar are most productive. This stored energy is then released during high-demand periods, such as evenings or overcast days, ensuring a consistent energy supply. Additionally, ESS can quickly respond to any upsurge in power demand, helping maintain grid stability. This approach not only stabilizes the grid during peak times but also reduces reliance on fossil-fuel-based peaking power plants, thereby decreasing greenhouse gas emissions. By smoothing energy production and consumption fluctuations, these systems enhance the efficiency of renewable resources.

Driving Sustainability through E-Waste Reduction and Circular Economy

Reducing e-waste and promoting sustainable manufacturing practices is a key priority for companies in the sector. They focus on resource optimization and sustainable material use in all their products, including energy storage systems. The battery manufacturing units implement Zero Liquid Discharge (ZLD) processes and utilize batteries that are over 99% recyclable, with more than 70% of the materials being recycled, ensuring sustainability and promoting a strong circular economy.

A key aspect of their sustainability strategy is the recovery and reuse of materials. They have achieved a milestone with a 100% success rate in used battery collection, supporting a cyclical economy. Additionally, these companies actively participate in European Stock Exchange sustainability reporting, emphasizing efforts to reduce Scope 3 emissions across their supply chain. These actions demonstrate their commitment to integrating sustainability at every level of business operations, ensuring that energy storage solutions are both environmentally friendly and efficient.

Energy Storage and Solar Solutions for a Greener Future

Battery energy storage systems play a vital role in optimizing the use of renewable energy by storing excess energy generated during periods of high production, such as peak sunlight hours when solar energy is most abundant. This stored energy is then released during times of lower production, such as at night or during cloudy weather, ensuring a continuous and stable power supply. Additionally, energy storage enhances electricity access through distributed energy systems. By storing energy locally, it enables power supply to communities or areas that may be underserved by traditional energy infrastructure. Most of the companies in this sector focus on improving energy accessibility and equity, facilitating broader adoption of renewable energy, especially in rural or off-grid regions. Through energy storage, they aim to create a more reliable, sustainable, and accessible energy system for all.

Leading electrical companies are advancing renewable energy technologies with a focus on solar solutions, including off-grid, hybrid, and GTI systems, to support India’s 500 GW renewable energy goals by 2030 and reduce reliance on conventional sources. They prioritize eco-design, resource optimization, and recyclable energy storage components. Their industrial facilities contribute to carbon footprint reduction through water conservation and plantation efforts, while participation in European Stock Exchange sustainability reporting highlights their commitment to reducing Scope 3 emissions across their supply chains.

Looking Ahead

Technology plays a pivotal role in advancing sustainable and energy-efficient solutions. By integrating advanced technologies in products such as off-grid, hybrid, and GTI solar systems, these companies empower residential and small industrial units with reliable and clean energy solutions, improving energy access even in remote areas. Innovations like energy management apps provide consumers with tools to monitor solar energy consumption, track savings, and evaluate environmental impacts in real-time, fostering energy literacy and proactive energy management. These advancements contribute to environmentally friendly solutions while improving quality of life and promoting a sustainable and healthier society.
