Dr S B Hegde, Professor, Department of Civil Engineering, Jain College of Engineering and Technology, Hubli, and Visiting Professor, Pennsylvania State University, USA, discusses the hydrogen and automation revolutions in the cement industry in the concluding part of this two-part series.

The global cement industry is undergoing a transformative phase by embracing the hydrogen revolution as a beacon of sustainable energy. This paradigm shift involves the incorporation of green hydrogen as a clean energy source, not only reducing environmental impact but also establishing new benchmarks for responsible energy use in cement production.

Usage of hydrogen in cement plants.
A. Global status
Globally, several leading cement manufacturers have initiated pilot projects and full-scale implementations of hydrogen-based technologies in cement production. As of the latest data, the cement industry accounts for approximately 7 per cent of global carbon dioxide emissions, making the adoption of green hydrogen crucial for achieving emission reduction targets.
In Germany, for instance, a prominent cement plant has invested over €40 million (approximately US$ 45 million) in a green hydrogen project. This initiative is expected to replace a significant portion of traditional fossil fuels, leading to a substantial reduction in carbon emissions.
B. Indian perspective
In the Indian context, the hydrogen revolution is gaining momentum as the cement industry strives to align with the nation’s commitment to sustainable development. While still in the early stages, pioneering cement plants in India are actively exploring the integration of green hydrogen into their production processes.
C. Current initiatives and investments in India
An exemplary case is a major cement manufacturer in India investing Rs 120 crores (approximately US$ 16 million) in a green hydrogen pilot project. This initiative aims to assess the feasibility of using green hydrogen as a primary fuel in cement kilns, with the potential to reduce carbon emissions by up to 30 per cent.
D. Challenges and opportunities
Despite the promising trajectory, challenges such as the cost of green hydrogen production and infrastructure development need to be addressed for widespread adoption. The Indian government’s focus on promoting green hydrogen and the establishment of a National Hydrogen Mission indicate a conducive environment for overcoming these challenges.
E. Environmental impact
The incorporation of green hydrogen into cement production offers a significant reduction in greenhouse gas emissions. As hydrogen combusts without producing carbon dioxide, it presents a cleaner alternative to traditional fossil fuels, aligning with global efforts to mitigate climate change.
F. Setting new standards
By embracing the hydrogen revolution, the cement industry is not only reducing its environmental impact but also setting new standards for responsible energy use. This shift positions cement manufacturers as leaders in sustainable practices and reinforces their commitment to a low-carbon future.
G. Future trajectory
The hydrogen revolution in cement production is poised to become a cornerstone of sustainable manufacturing globally and in India. Continued investments, collaborative research, and government support are expected to drive the widespread adoption of green hydrogen, ushering in a new era of responsible and environmentally conscious cement production.
Automation Revolution
As the cement industry propels into the future, a seismic shift is underway, steering towards a highly automated and robotic workforce. This commitment to automation transcends geographical boundaries, reshaping the landscape of cement production with a focus on precision, safety, and unparalleled efficiency. Let’s delve into the global and Indian scenarios, incorporating some figures to the transformative impact of robotics in the cement industry.

Global landscape
A. Adoption of automation
Globally, leading cement manufacturers are at the vanguard of adopting automation and robotic technologies. According to industry reports, over 50 per cent of major cement plants worldwide have integrated robotic systems into their production processes, marking a substantial increase in the last five years.
B. Safety and precision
The paramount focus is on ensuring the safety of human workers and achieving precision in tasks that are critical to cement production. Studies show a 70 per cent reduction in workplace accidents in cement plants that have implemented robotics, demonstrating a tangible improvement in safety conditions.
C. Efficiency gains
Automated and robotic systems significantly enhance the efficiency of cement production. Reports indicate a 20 per cent increase in production efficiency and a 15 per cent reduction in downtime in cement plants where robotic technologies are fully integrated. These gains contribute to cost-effectiveness and operational excellence.

D. Examples of implementation
In Europe, a major cement plant has deployed autonomous robotic vehicles for transporting raw materials within the facility. This not only reduces manual labour but also streamlines the logistics process, contributing to a 25 per cent improvement in overall operational efficiency.

Indian scenario
A. Adopting trends
In India, the adoption of robotic systems in the cement industry is steadily gaining traction. According to industry forecasts, over 30 per cent of large cement plants in India have initiated or completed the integration of robotic solutions into their production processes, with projections indicating a further 15 per cent increase in the next three years.
B. Safety enhancement
With a commitment to worker safety, Indian cement plants are integrating robotics into tasks that involve potential risks. Reports suggest a 40 per cent reduction in accidents related to material handling and other hazardous processes in plants where robotic systems are actively employed.
C. Efficiency and precision
The Indian cement industry is witnessing increased efficiency and precision in production through the deployment of robotic systems. According to operational data, cement plants in India have experienced a 12 per cent improvement in packaging precision and a 30 per cent reduction in errors in tasks performed by robots.
D. Collaborations and investments
To expedite the adoption of robotics, Indian cement manufacturers are collaborating with robotics companies and investing in research and development. Industry reports indicate that the Indian cement sector has witnessed a 25 per cent increase in investments in robotic technologies in the last two years.
E. Future trajectory
The future of cement production globally and in India is undeniably linked to the continued integration of robotic technologies. As advancements in robotics and automation unfold, the industry is poised to witness further improvements in safety, precision and overall efficiency.
