With electric vehicles (EVs) leading the green revolution, providing a cleaner and more sustainable transportation option, the supply chain of cement is getting redefined. Raman Bhatia, Founder and Managing Director, Servotech Power Systems, talks about the inherent challenges in this transformation.

India is currently witnessing a revolution in its transportation landscape, propelled by a unified commitment to combat climate change and decrease our reliance on fossil fuels. EVs are at the forefront of this revolution, offering a cleaner, more sustainable mode of transportation. The paradigm shift from internal combustion engine (ICE)-driven vehicles to EVs calls for smart and sustainable charging infrastructure development. Uncoordinated charging may result in serious consequences such as voltage stability, power losses, degradation of reliability indices and an increase in the peak load. At the same time, ensuring energy sustainability, the development of the renewable-based charging infrastructure, and an increase in the share of renewables in the national energy mix are given priority. Hence, planning smart and sustainable EV charging infrastructure and coordinating charging activities have emerged as prime concerns worldwide.

Sustainable EV Charging Infrastructure
Sustainable charging refers to the use of clean energy to power EV charging stations. Sustainable charging solutions deliver environmental benefits where EV owners can charge their vehicles without negatively affecting the environment. Apart from this, sustainable charging solutions also enable EV owners to charge their vehicles at low-cost rates, incentivising the adoption of electric vehicles over conventional vehicles. One such sustainable charging solution is solar-powered EV charging carport, which has managed to redefine the landscape of EV charging infrastructure with its innovative approach.
Solar carports are covered parking areas whose roof is made from PV panels and can be installed residentially and commercially. Positioned at the intersection of renewable energy and parking infrastructure, solar carports are harnessing the sun’s power to revolutionise electricity generation while simultaneously providing essential shade and shelter for parked vehicles. The electricity generated by the solar carports can be used to charge EVs or sent back to the grid.
Using solar energy to charge EVs amplifies the environmental impact of driving an EV. Rather than using electricity from the grid, which could be sourced from fossil fuels or a mix of clean and dirty sources, the EV is charged from clean, renewable energy. The amount of electricity generated by a solar carport depends on the size of the carport, the number of solar panels it has installed, as well as environmental factors, such as the number of daylight hours and the intensity of the light. However, on average, a solar carport can generate enough energy to charge several EVs per day and space using Level 2 chargers.

Advantages of Solar Carport Charging Stations
Solar Carport EV charging stations, with their multifaceted advantages, are revolutionising the electric vehicle charging landscape. They harness solar power for eco-friendly charging, reducing environmental impact. These structures also protect EVs from harsh weather, enhancing longevity. In urban areas, they optimise land use, offering both shelter and renewable energy. The integration of carport charging stations with the grid, with bi-directional energy flow capabilities, enhances grid stability and supports renewable energy integration. These stations, by generating their electricity, can potentially offer cost savings, making EV adoption more appealing. With scalability, carport charging stations are adaptable for individual homes or large-scale charging networks, offering a versatile and efficient solution for diverse environments.

Solar carports’ versatility allows them to be applied in various sectors, including commercial, residential, industrial, and public infrastructure, expanding their market potential.

Multi-Faceted Role of Solar Carports
The cement industry plays a significant role in infrastructure development worldwide. However, like any industrial sector, it faces the pressing challenges of sustainability and operational efficiency. As industries increasingly explore eco-friendly and cost-effective solutions, carports have emerged as a valuable addition to the cement manufacturing process since they offer multifaceted benefits to the cement industry. One of the most prominent and innovative applications of carports in the cement industry is turning them into solar power stations.


The clean solar energy generated from these power stations can be integrated into the cement production process, significantly reducing electricity costs and the surplus energy generated can be channelled back into the grid, contributing to a sustainable and cost-effective energy solution. The cement manufacturing process involves the storage of raw materials, equipment and finished products. Exposure to harsh weather conditions can lead to damage, loss, and deterioration of materials and equipment. Carports offer covered storage, protecting these valuable assets from rain, sun, and other environmental elements. This enables the cement industry to extend its products’ lifespan, reduce maintenance costs, and maintain product quality. Carports can also enhance the working environment for employees. When installed in employee parking areas, carports provide shade and protection from rain or extreme heat. This not only improves the overall well-being and comfort of the workforce but also boosts morale, job satisfaction, and productivity. The cement manufacturing process can generate dust and particulates, which pose environmental and health challenges. Strategically designed carports can incorporate filtration systems or be engineered to contain dust, helping control air pollution within the manufacturing facility. Cement production requires substantial amounts of water, making it a resource-intensive industry. Carports equipped with collection systems can harvest rainwater. This water can then be treated and used for various purposes within the manufacturing process, conserving water resources and reducing water supply costs.

Looking Forward
The global shift towards cleaner energy sources is fueling the demand for EVs. Solar carports are emerging as a promising solution to provide covered parking spaces equipped with canopies to shield EVs from sunlight. These carports offer an eco-friendly approach to EV charging by combining clean solar energy with user convenience. As the popularity of electric vehicles continues to grow, the installation and acceptance of solar carports are expected to rise in tandem to meet the energy demands of EVs. The flexibility and versatility of solar carports, which can generate electricity for domestic use and grid credits, are contributing to market expansion.
Solar energy is becoming an integral part of the energy mix, further propelling the market’s growth. Additionally, the optimal placement of solar panels in solar carports enhances their effectiveness, making them a preferred choice for sustainable energy solutions. Moreover, the integration of solar carports into the cement manufacturing process offers a versatile and sustainable solution. These structures not only generate clean energy but also provide valuable shelter and environmental benefits, contributing to overall efficiency, cost savings and environmental responsibility in the industry.

World’s biggest cement producers bet on green alternative

Holcim and CRH announced a $75 million investment.

Two of the world’s biggest cement producers, Holcim AG and CRH PLC, are investing in a startup attempting to decarbonize the cement production process. Cement and concrete are responsible for about 8% of emissions, more than any other industrial sector.

Holcim and CRH announced a $75 million investment into Sublime Systems, including a promise to purchase green cement from the startup’s pilot facilities and to work with Sublime on additional plant sites. (CRH invested through its venture arm.) Somerville, Massachusetts-based Sublime has developed an electrochemical method of cement production that avoids the process of heating up limestone with kilns powered by fossil fuels.

Reducing cement emissions has long been a technological and economic challenge. Cement is essential to making concrete, and to roads, buildings and other critical infrastructure. But the material’s production generates carbon dioxide emissions from burning fuel (often coal) to heat kilns, from the decomposition of limestone and from quarrying, grinding and transforming the materials.

In tests at its 250-ton-per-year pilot plant, Sublime has been able to demonstrate a 90% reduction in CO2 emissions compared to traditional concrete, according to Leah Ellis, co-founder and chief executive officer. The company is developing a commercial plant in Holyoke, Massachusetts, that would have a capacity of 30,000 tons per year and is set to be completed in 2026. The Energy Department’s Office of Clean Energy Demonstrations will fund up to 50% of that plant’s construction.

Ellis said Sublime’s goal is to provide its technology to larger cement companies with existing infrastructure and supply chains, which would either build new cement plants with the tech or retrofit old ones.

While Sublime’s process generates far fewer emissions, there are many hurdles the company and others like it need to overcome before they can commercialize successfully. One major limitation is the significant capital costs associated with retrofitting cement plants — often large, custom operations — or building new ones.

Another is demand: Low-carbon cement remains more expensive, on average, than traditional cement, making it a hard sell for a construction industry that already operates on razor-thin margins. New regulations, including New York’s mandate for state agencies to buy clean concrete, could help boost demand, said Ash Lauth, a senior campaign strategist for the global cement initiative at Industrious Labs, a US-based nonprofit focused on industrial decarbonization. But the industry still has a long way to go: Last week, Industrious Labs published an analysis that gave Holcim a “D” grade on its sustainability efforts.

“While we’re encouraged that Holcim is investing in Sublime’s innovative technology, we also still want them to show up for the rest of the ways to decarbonize… and work towards issuing a clear and transparent plan for how they’re going to decarbonize their existing US fleets,” Lauth said. Nollaig Forrest, Holcim’s chief sustainability officer, said Holcim is among “the only players in our sector that really takes a whole value chain approach to decarbonizing building at scale.”

The investment from Holcim and CRH brings Sublime’s total funding to over $200 million since its founding in 2020. It’s another signal of confidence in the startup, which was one of six projects selected for the Energy Department’s $1.6 billion program to fund cement and concrete decarbonization.

The Gujarat High Court has halted criminal proceedings and summons issued against Kumar Mangalam Birla, his mother Rajashree Birla, and seven other directors of UltraTech Cement by a Vadodara court, following a criminal complaint.

The summons had been issued on September 9 by the Vadodara chief judicial magistrate in connection with a case filed by Abhishek Shrivastava, the proprietor of Srimech Engineering. The directors of UltraTech Cement subsequently approached the High Court to challenge the summons. It was argued before the court that there had been a contract between Srimech and UltraTech for the supply of limestone.

This contract, related to mining in Madhya Pradesh, was later terminated by UltraTech for certain reasons, prompting Srimech to file a commercial suit in Rewa district, Madhya Pradesh, in November of the previous year.

The petitioners’ counsel argued that despite this ongoing commercial dispute, Shrivastava had filed a criminal case in the Vadodara court, which lacked jurisdiction to entertain the matter. The court was informed that the issues raised in the criminal complaint were identical to those in the commercial suit.

The counsel further argued that since the complainant had already pursued a civil remedy, the continuation of criminal proceedings would constitute an abuse of legal processes.

In response, Justice Nirzar Desai granted interim relief to the petitioners, staying the Vadodara court proceedings, and issued notices to the state government and the complainant. The case is set for further hearing on December 3.
