Even as the world’s energy utilisation is growing at 2.6 per cent, India is at 6.8 per cent. G Jayaraman shares his thoughts on how to ensure fuel security in the country.
Energy security in India seems to be seeing rough weather, with the state- owned Coal India (CIL) and Oil and Natural Gas Commission (ONGC) failing to meet their targets year after year. CIL again seems to be aiming at producing 482 million tonnes of coal this year and 650 million tonnes by 2016-17, a substantial shortfall of over 20 per cent from target. ONGC has been witnessing a constant decline in assets output within and outside the country. It has slipped from 9.4 million tonnes in 2010-11 to 7.2 million tonnes in 2012-13. Even ONGC’s overseas arm, ONGC Videsh (OVL), has been experiencing an unexpected fall in production in recent years.
Thus, a growing country like India has to depend on fossil fuels like oil and coal for a few more decades, until renewable energy (RE) becomes economically viable and substantially large enough to meet the growing needs of the country.
This brings us to the important question: what is energy security?
Everyone will agree that the energy that ensures
(i) stable generation and supply;
(ii) dependability and
(iii) cost- effectiveness, is what can be classified as secured energy.
A look at Indian energy reserves and its present utilisation will show startling under- utilisation. The reasons could be many but the net result is a huge energy shortage which is affecting the country’s economic growth.
The present shortfall in energy generation is attributed mainly to the following causes:
- There is no growth in coal generation. As already stated, there is a stagnancy in expanding the existing coal mines as well as in opening up and exploiting new coal reserves. The state- run CIL is stuck due to problems with land acquisition, environmental and forest clearances. The same is the case with the ONGC, too.
- The quality of coal is under severe criticism even by the other state- owned organisations. NTPC has been in a longdrawn drawn battle with CIL on the quality of coal supplied to its thermal plants, to the extent of even withholding clearance of coal bills. The industry does not find any proper redressal mechanism to take up the poor quality of supplies from CIL.
- Imports have been on the increase year after year. Today, it is almost in the region of 150 million tonnes which is further burdening the fast depleting foreign exchange reserves.
- The international prices of coal have also shot up considerably, thanks to the fall in rupee value, making the earlier power purchase agreements becoming unviable. Sluggish infrastructural developments, particularly for rail and road is another problem. Today, 50 per cent of coal traffic is by rail transport. It is saddled with a mismatched traffic pattern, only 16 per cent of the railway network carries 55 per cent of the traffic and 45 per cent of the passenger.
- Road development is very inadequate and transport costs are highly prohibitive. The restriction on loading of commercial vehicles up to their rated capacity under the orders of the Supreme Court of India, resulting in an increase in the cost of transportation by almost 25 per cent, is perhaps, one of the major reasons for the steep inflationary trend seen in the last three years.
- India is the fifth largest energy consumer. We are consuming 4.4 per cent of the world’s energy at around 525 million tonnes oil equivalent (mtoe). Where the world energy utilisation is growing at 2.6 per cent, India is at 6.8 per cent. Oil and gas constitute 45 per cent of the total energy consumption and coal is at 35 per cent. Hydro energy is around 17 per cent and all other renewable energy like nuclear, wind, solar, geo-thermal, waste derived fuels are in decimals.
- The energy situation in future is not too bright as even if we exploit hydro potential to its halfway mark ; even if there is a forty- fold increase in renewable energy supply; even if we manage a twenty-four- fold increase in nuclear energy plants, fossil fuels, mainly coal, will continue to be the most significant source of energy supply even after 2030-35.
The way forward
There has to be a positive approach towards the framing of policies. Today, reform seems to be one- sided: to facilitate foreign investment. This is not reform. Reform is the process by which the consumer finds it easy to get the products and services from the government’s agencies with the least procedural delays, simplified and easy to understand methodology, and is assured of his rights as a consumer. Any other type of arrangement to increase the financial side cannot be considered reforms until the basic requirements are met.
There has to be a standard for energy supplies, a benchmark on the prices and a proper quality redressal mechanism to ensure the right energy services to the industry and the common man.
Some of the issues which are hurdles to energy growth are:
- Environmental clearances Create a one-window approach instead of involving independent ministries, viz; E&F, coal, power.
- Cut delays that arise from ambiguity in rules, interpretation for undue advantage, and lack of will to take decisions.
Social problems
Review the National Rehabilitation & Resettlement (RR) Policy 2007
Make allotment of lands to projects based on:
- Market price.
- One-time compensation to owners.
- Return the land to owners if not in use for five years and more.
- Land- owner’s share in business.
Infrastructure hurdles
Improve system reliability by dedicated freight corridors in the rail and road network.
Entry barriers to be set up between states.Exclusive flyovers/speed tracks to be set up for 24×7 movement of heavy vehicles in cities/big towns.
Full exploitation of renewable energy sources
National policy on linking rivers.
People-friendly strategy on macro and mini hydro projects.
Lands on long- term lease for wind and solar projects.
Develop hydrogen cells from electrolysis with solar / wind / hydro energy.
New exploration and R&D
Involve public/private partnership.
FDI in exploration, infrastructure, energy reduction technology products and processes. Coal washery at pit head and waste coal to be used for Coal India’s power plants.
Prospects
The progress in both thermal energy generation, as well as renewable energy generation, have been very encouraging.
The new technology of super critical thermal stations have a lower greenhouse per 750 gm/kwh as against the national average of 1260 gm/kwh, and show great promise for an environmentaly l friendly thermal generation. There have also been improvements in boiler efficiencies and lower sulphar emissions in operating the thermal plants.
The consumers also have a major role to play. There has to be regulation in using most energy- efficient appliances both at home and industry, and a pro-active action for retrofitting energy- efficient plants and machinery.
Waste recovery systems have already been well established and it makes economic sense to install a proper waste recovery systems in all high temperature applications.
Waste derived fuel is another area which isnot much in use in India primarily, because there are no agencies that can collect, process, store and supply the waste derived fuels. Municipal solid wastes (MSW) at 6 million tonnes/day all over India, if properly collected and converted into fuel could meet more than ten per cent of India’s energy requirement.
The way the MSW is disposed of for natural gasification and incineration is a callous act of disastrous consequences to human health. Capital investment in solar energy has been inactive in the last three years. Within the next five years, investment in solar energy will get quite competitive, with the investment in thermal plants. This is one area which requires continuous government support in terms of the purchase price of electricity from solar plants.
It is disturbing to note that a few state governments are proposing to bring down the purchase price for solar electricity by more than 30-40 per cent, justifying it on the move towards lower capital investment. Unless substantial profits are allowed to be generated from solar plant installations, the growth in solar energy will see a major fall as it happened in wind power investments. This, of course, will not be in India’s interest, particularly when more than 85 per cent of its oil requirement is still dependant on imports.

In this insightful article, KB Mathur, Founder and Director, Global Technical Services, explores how reclaiming used lubricants through advanced filtration and on-site testing can drive cost savings, enhance productivity, and support a greener industrial future. Read on to discover how oil regeneration is revolutionising sustainability in cement and core industries.
The core principle of the circular economy is to redefine the life cycle of materials and products. Unlike traditional linear models where waste from industrial production is dumped/discarded into the environment causing immense harm to the environment;the circular model seeks to keep materials literally in continuous circulation. This is achievedthrough processes cycle of reduction, regeneration, validating (testing) and reuse. Product once
validated as fit, this model ensures that products and materials are reintroduced into the production system, minimising waste. The result? Cleaner and greener manufacturing that fosters a more sustainable planet for future generations.
The current landscape of lubricants
Modern lubricants, typically derived from refined hydrocarbons, made from highly refined petroleum base stocks from crude oil. These play a critical role in maintaining the performance of machinery by reducing friction, enabling smooth operation, preventing damage and wear. However, most of these lubricants; derived from finite petroleum resources pose an environmental challenge once used and disposed of. As industries become increasingly conscious of their environmental impact, the paramount importance or focus is shifting towards reducing the carbon footprint and maximising the lifespan of lubricants; not just for environmental reasons but also to optimise operational costs.
During operations, lubricants often lose their efficacy and performance due to contamination and depletion of additives. When these oils reach their rejection limits (as they will now offer poor or bad lubrication) determined through laboratory testing, they are typically discarded contributing to environmental contamination and pollution.
But here lies an opportunity: Used lubricants can be regenerated and recharged, restoring them to their original performance level. This not only mitigates environmental pollution but also supports a circular economy by reducing waste and conserving resources.
Circular economy in lubricants
In the world of industrial machinery, lubricating oils while essential; are often misunderstood in terms of their life cycle. When oils are used in machinery, they don’t simply ‘DIE’. Instead, they become contaminated with moisture (water) and solid contaminants like dust, dirt, and wear debris. These contaminants degrade the oil’s effectiveness but do not render it completely unusable. Used lubricants can be regenerated via advanced filtration processes/systems and recharged with the use of performance enhancing additives hence restoring them. These oils are brought back to ‘As-New’ levels. This new fresher lubricating oil is formulated to carry out its specific job providing heightened lubrication and reliable performance of the assets with a view of improved machine condition. Hence, contributing to not just cost savings but leading to magnified productivity, and diminished environmental stress.
Save oil, save environment
At Global Technical Services (GTS), we specialise in the regeneration of hydraulic oils and gear oils used in plant operations. While we don’t recommend the regeneration of engine oils due to the complexity of contaminants and additives, our process ensures the continued utility of oils in other applications, offering both cost-saving and environmental benefits.
Regeneration process
Our regeneration plant employs state-of-the-art advanced contamination removal systems including fine and depth filters designed to remove dirt, wear particles, sludge, varnish, and water. Once contaminants are removed, the oil undergoes comprehensive testing to assess its physico-chemical properties and contamination levels. The test results indicate the status of the regenerated oil as compared to the fresh oil.
Depending upon the status the oil is further supplemented with high performance additives to bring it back to the desired specifications, under the guidance of an experienced lubrication technologist.
Contamination Removal ? Testing ? Additive Addition
(to be determined after testing in oil test laboratory)
The steps involved in this process are as follows:
1. Contamination removal: Using advanced filtration techniques to remove contaminants.
2. Testing: Assessing the oil’s properties to determine if it meets the required performance standards.
3. Additive addition: Based on testing results, performance-enhancing additives are added to restore the oil’s original characteristics.
On-site oil testing laboratories
The used oil from the machine passes through 5th generation fine filtration to be reclaimed as ‘New Oil’ and fit to use as per stringent industry standards.
To effectively implement circular economy principles in oil reclamation from used oil, establishing an on-site oil testing laboratory is crucial at any large plants or sites. Scientific testing methods ensure that regenerated oil meets the specifications required for optimal machine performance, making it suitable for reuse as ‘New Oil’ (within specified tolerances). Hence, it can be reused safely by reintroducing it in the machines.
The key parameters to be tested for regenerated hydraulic, gear and transmission oils (except Engine oils) include both physical and chemical characteristics of the lubricant:
- Kinematic Viscosity
- Flash Point
- Total Acid Number
- Moisture / Water Content
- Oil Cleanliness
- Elemental Analysis (Particulates, Additives and Contaminants)
- Insoluble
The presence of an on-site laboratory is essential for making quick decisions; ensuring that test reports are available within 36 to 48 hours and this prevents potential mechanical issues/ failures from arising due to poor lubrication. This symbiotic and cyclic process helps not only reduce waste and conserve oil, but also contributes in achieving cost savings and playing a big role in green economy.
Conclusion
The future of industrial operations depends on sustainability, and reclaiming used lubricating oils plays a critical role in this transformation. Through 5th Generation Filtration processes, lubricants can be regenerated and restored to their original levels, contributing to both environmental preservation and economic efficiency.
What would happen if we didn’t recycle our lubricants? Let’s review the quadruple impacts as mentioned below:
1. Oil Conservation and Environmental Impact: Used lubricating oils after usage are normally burnt or sold to a vendor which can be misused leading to pollution. Regenerating oils rather than discarding prevents unnecessary waste and reduces the environmental footprint of the industry. It helps save invaluable resources, aligning with the principles of sustainability and the circular economy. All lubricating oils (except engine oils) can be regenerated and brought to the level of ‘As New Oils’.
2. Cost Reduction Impact: By extending the life of lubricants, industries can significantly cut down on operating costs associated with frequent oil changes, leading to considerable savings over time. Lubricating oils are expensive and saving of lubricants by the process of regeneration will overall be a game changer and highly economical to the core industries.
3. Timely Decisions Impact: Having an oil testing laboratory at site is of prime importance for getting test reports within 36 to 48 hours enabling quick decisions in critical matters that may
lead to complete shutdown of the invaluable asset/equipment.
4. Green Economy Impact: Oil Regeneration is a fundamental part of the green economy. Supporting industries in their efforts to reduce waste, conserve resources, and minimise pollution is ‘The Need of Our Times’.
About the author:
KB Mathur, Founder & Director, Global Technical Services, is a seasoned mechanical engineer with 56 years of experience in India’s oil industry and industrial reliability. He pioneered ‘Total Lubrication Management’ and has been serving the mining and cement sectors since 1999.

The Indian cement industry has reached a critical juncture in its sustainability journey. In a landmark move, the Ministry of Environment, Forest and Climate Change has, for the first time, announced greenhouse gas (GHG) emission intensity reduction targets for 282 entities, including 186 cement plants, under the Carbon Credit Trading Scheme, 2023. These targets, to be enforced starting FY2025-26, are aligned with India’s overarching ambition of achieving net zero emissions by 2070.
Cement manufacturing is intrinsically carbon-intensive, contributing to around 7 per cent of global GHG emissions, or approximately 3.8 billion tonnes annually. In India, the sector is responsible for 6 per cent of total emissions, underscoring its critical role in national climate mitigation strategies. This regulatory push, though long overdue, marks a significant shift towards accountability and structured decarbonisation.
However, the path to a greener cement sector is fraught with challenges—economic viability, regulatory ambiguity, and technical limitations continue to hinder the widespread adoption of sustainable alternatives. A major gap lies in the lack of a clear, India-specific definition for ‘green cement’, which is essential to establish standards and drive industry-wide transformation.
Despite these hurdles, the industry holds immense potential to emerge as a climate champion. Studies estimate that through targeted decarbonisation strategies—ranging from clinker substitution and alternative fuels to carbon capture and innovative product development—the sector could reduce emissions by 400 to 500 million metric tonnes by 2030.
Collaborations between key stakeholders and industry-wide awareness initiatives (such as Earth Day) are already fostering momentum. The responsibility now lies with producers, regulators and technology providers to fast-track innovation and investment.
The time to act is now. A sustainable cement industry is not only possible—it is imperative.
