Clean Coal Technology in India: A potential solution to meet increasing energy needs

Published

Authors: Sanjay Kumar Kar and Ms. Harsha*

[yt_dropcap type=”square” font=”” size=”14″ color=”#000″ background=”#fff” ] C [/yt_dropcap]oal has been an integral component of the global fuel mix for a long, long time now. To provide the reader with some numerical perspective, the world depends on coal for a total of around 30% of its energy needs. For India, this figure is around 55%, with sectors like power generation, steel, cement industry, paper and textile industries being the major consumers.

In 2015, with a carbon emission share of about 7% India was the 3rd largest carbon dioxide (CO2) emitter behind China (27%) and the USA (16%). Further, carbon emission is complicated with coal burning in Jharia coal field in the eastern India.

Coal is the dirtiest of all the fossil fuels. It is a well-known fact that burning of coal, be it for any use, produces CO2, sulphurous oxides, nitrous oxides, and sooty particulate matter. These emissions, unfortunately, have detrimental effects on environment. To tackle emission of greenhouse gases, governments all over the world have started moving towards less polluting sources of energy, with huge emphasis on renewable resources like solar, wind, hydro and nuclear energy.

New Delhi is equally concerned and committed towards green energy for future growth. It has taken various initiatives, like promotion of solar power projects, setting up of biogas/mass and cogeneration plants, investing in onshore and offshore wind installations. Further, government with serious intent is pursuing repowering of old wind mills and objectively pushing development of offshore wind developments. In line with India’s INDC declaration, dependence on renewable sources of energy is bound to grow in the near future. Government’s target of achieving 175 GW of grid connected renewable energy by 2022 from current base of 45 GW, which looks a distant dream but not beyond reach.

All said and done, India’s dependency on coal, especially for power generation remains as a big concern for environmentalist and policy makers. Dependency on coal is likely to come down marginally because efficiency of renewable technology is much lower than coal based power plants. Therefore, it is reasonable to accept dependency on coal would continue for at least a decade or more. Under the emerging scenario, India needs to find a middle ground to address its energy security and meeting INDC target of cutting 30-33% carbon emission by 2030.

India is pursuing multipronged strategies revolving around green energy and diversified energy mix to address energy security. One of the feasible options is clean coal technology (CCT), which largely addresses mitigation of emission. Some of the CCT based methods deployed are coal washing, wet scrubbers, or flue gas desulfurization systems, electrostatic precipitators, low-NOx (nitrogen oxide) burners, and integrated gasification combined cycle (IGCC) systems. Gasification is a process that avoids burning coal altogether offers efficiency in the range of 40-60%.

India began its pursuit of R&D on Coal Beneficiation, Coal Gasification, Liquefaction, and IGCC in the early 1980s. Further, constant efforts are being made for introduction, adaptation, and development of clean coal technologies through policies and programmes in the country. A dedicated government chapter for further research and development has been set up, called the National Clean Coal Technology Centre (NCCTC).

Considering shortage of domestic petroleum and natural gas supply in India, dependency on coal in the immediate future is understandable. Therefore, in the last decade special focus was put on supercritical power plants. These plants offer higher efficiency and lower carbon emissions because they generate lesser carbon for the same amount of coal burnt.

The government has gone as far as saying that all new coal power plants will be making use of clean technology. It is estimated that about 100 GW of clean coal based power installation would be added by 2025. Shri Piyush Goyal, Union Minister of State (IC) for Power, Coal and New & Renewable Energy strongly supports clean coal technologies, therefore with all probability clean coal initiatives would be successful.

Despite clean coal technology offering benefits like low coal consumption, higher efficiency, and lower greenhouse gas emissions; there are not many takers.

The advancement of CCTs is facing several barriers in the forms of (i) high cost involved to support development of CCT to proving stage, (ii) amenability of advanced technologies to available coal with high ash content, (iii) inadequate R&D infrastructure in academic institutions and national laboratories, (iv) lack of academic–industry interaction for new coal-based technology, (v) constraints in development of coal blocks in the absence of adequate equipment infrastructure (vi) lack of sufficient coal evacuation facilities, and (vii) financing clean coal technologies.

In India, almost 40% of the available coal resources are deep seated (beyond 300 meters depth) which could be ideal for underground coal gasification. This is another clean coal technology that could be harnessed effectively.

As a result of increasing concerns for global warming, prospects of CCTs are becoming far more realistic. Clean coal technology can help addressing both the local as well the global environment concerns. It may take some time to establish the economic competitiveness of the technology, but the costs are definitely coming down. A long-term clean coal policy to address issues of installation of thermal power plants based on CCTs, R&D, and transfer of technology is the need of hour. Most CCTs are research intensive and are still evolving, therefore, joint research ventures should be considered for technology transfer. In super-critical and ultra-super-critical coal fired plants, much higher efficiency can be achieved. The super-critical technology is already under development in India. These facilities and technology need to be worked upon to pave way for ultra-critical technologies.

With the given current scenario, even environmentalists agree that coal is a necessary evil. India needs to push the renewable energy sector aggressively, but in the meanwhile, CCTs are the way to go. Presently, nearly two-thirds of India’s power comes from coal and only a tenth of it is generated from clean coal. The government has targeted that the share of clean coal will go up to 24 per cent by 2022.

To be frank, coal, in its true sense, wouldn’t ever be clean—but it could be used in a cleaner manner than it is today. And we, the humble residents of the planet, would be much better off with the help of the clean coal technology.

Asia’s policy makers should strengthen cooperation to harness the potential of new financial technologies for inclusive growth. At the same time, they should work together to ensure they can respond better to the challenges posed by fintech.

New technologies such as mobile banking, big data, and peer-to-peer transfer networks are already extending the reach of financial services to those who were previously unbanked or out of reach, boosting incomes and living standards. Yet, fintech also comes with the risk of cyber fraud, data security, and privacy breaches. Disintermediation of fintech services or concentration of services among a few providers could also pose a risk to financial stability.

These and other issues were discussed at the High-Level Policy Dialogue on Regional Cooperation to Support Innovation, Inclusion, and Stability in Asia, organized by the Asian Development Bank (ADB), Bank Indonesia, and the ASEAN+3 Macroeconomic Research Office (AMRO).

The panel comprised Ms. Neav Chanthana, Deputy Governor of the National Bank of Cambodia; Mr. Diwa Guinigundo, Deputy Governor of Bangko Sentral ng Pilipinas; Ms. Mary Ellen Iskenderian, President and Chief Executive Officer of Women’s World Banking; Mr. Ravi Menon, Managing Director of the Monetary Authority of Singapore; Mr. Takehiko Nakao, President of ADB; Mr. Abdul Rasheed, Deputy Governor, Bank Negara Malaysia, and Mr. Veerathai Santiprabhob, Governor of the Bank of Thailand. Mr. Mirza Adityaswara, Senior Deputy Governor of Bank Indonesia, gave the opening remarks at the conference and Ms. Junhong Chang, Director of AMRO, gave the welcome remarks.

“Rapidly spreading new financial technologies hold huge promise for financial inclusion,” said Mr. Nakao. “We must foster an enabling environment for the technologies to flourish and strengthen regional cooperation to build harmonized regulatory standards and surveillance systems to prevent international money laundering, terrorism financing, and cybercrimes.”

“Technology is an enabler that weaves our economies and financial systems together, transmitting benefits but also risks across borders,” said Ms. Chang. “Given East Asia’s rapid economic growth, understanding and managing the impact of technology in our financial systems is essential for policymakers to maintain financial stability.”

“Asia, including Indonesia, is an ideal place for fintech to flourish,” said Mr. Adityaswara. “In Indonesia’s case, there are more than a quarter of a billion people living on thousand of islands, waiting to be integrated with the new technology; young people eager to enter the future digital world; more than fifty million small and medium-sized enterprises which can’t wait to get on board with e-commerce; a new society driven by a dynamic, democratic middle class which views the digital economy as something as inevitable as evolution.”

Despite Asia’s high economic growth in recent years, the financial sector is still under-developed in some countries. Fewer than 27% of adults in developing Asia have a bank account, well below the global median of 38%. Meanwhile, just 84% of firms have a checking or savings account, on a par with Africa but below Latin America’s 89% and emerging Europe’s 92%.

Financial inclusion could be increased through policies to promote financial innovation, by boosting financial literacy, and by expanding and upgrading digital infrastructure and networks. Regulations to prevent illegal activities, enhance cyber security, and protect consumers’ rights and privacy, would also build confidence in new financial technologies.

Cutting-edge tech a ‘double-edged sword for developing countries’

MD Staff

Published

The latest technological advances, from artificial intelligence to electric cars, can be a “double-edged sword”, says the latest UN World Economic and Social Survey (WESS 2018), released on Monday.

The over-riding message of the report is that appropriate, effective policies are essential, if so-called “frontier technologies” are to change the world for the better, helping us to achieve the Sustainable Development Goals (SDGs) and addressing climate change: without good policy, they risk exacerbating existing inequality.

Amongst several positive indicators, WESS 2018 found that the energy sector is becoming more sustainable, with renewable energy technology and efficient energy storage systems giving countries the opportunity to “leapfrog” existing, often fossil fuel-based solutions.

The wellbeing of the most vulnerable is being enhanced through greater access to medicines, and millions in developing countries now have access to low-cost financial services via their mobile phones.

Referring to the report, UN Secretary-General António Guterres said that “good health and longevity, prosperity for all and environmental sustainability are within our reach if we harness the full power of these innovations.”

However, the UN chief warned of the importance of properly managing the use of new technologies, to ensure there is a net benefit to society: the report demonstrates that unmanaged implementation of developments such as artificial intelligence and automation can improve efficiency but also destroy quality jobs.

“Clearly, we need policies that can ensure frontier technologies are not only commercially viable but also equitable and ethical. This will require a rigorous, objective and transparent ongoing assessment, involving all stakeholders,” Mr. Guterres added

The Survey says that proactive and effective policies can help countries to avoid pitfalls and minimize the economic and social costs of technology-related disruption. It calls for regulation and institutions that promote innovation, and the use of new technologies for sustainable development.

With digital technology frequently crossing borders, international cooperation, the Survey shows, is needed to bring about harmonized standards, greater flexibility in the area of intellectual property rights and ensuring that the market does not remain dominated by a tiny number of extremely powerful companies.

Here, the UN has a vital role to play, by providing an objective assessment of the impact that emerging technologies have on sustainable development outcomes – including their effects on employment, wages and income distribution – and bringing together people, business and organizations from across the world to build strong consensus-led agreements.

Our Trust Deficit with Artifical Intelligence Has Only Just Started

Eleonore Pauwels

Published

“We suffer from a bad case of trust-deficit disorder,” said UN Secretary-General António Guterres in his recent General Assembly speech. His diagnosis is right, and his focus on new technological developments underscores their crucial role shaping the future global political order. Indeed, artificial intelligence (AI) is poised to deepen the trust-deficit across the world.

The Secretary-General, echoing his recently released Strategy on New Technologies, repeatedly referenced rapidly developing fields of technology in his speech, rightly calling for greater cooperation between countries and among stakeholders, as well as for more diversity in the technology sector. His trust-deficit diagnosis reflects the urgent need to build a new social license and develop incentives to ensure that technological innovation, in particular AI, is deployed safely and aligned with the public interest.

However, AI-driven technologies do not easily fit into today’s models of international cooperation, and will in fact tend to undermine rather than enforce global governance mechanisms. Looking at three trends in AI, the UN faces an enormous set of interrelated challenges.

AI and Reality

First, AI is a potentially dominating technology whose powerful – both positive and negative –implications will be increasingly difficult to isolate and contain. Engineers design learning algorithms with a specific set of predictive and optimizing functions that can be used to both empower or control populations. Without sophisticated fail-safe protocols, the potential for misuse or weaponization of AI is pervasive and can be difficult to anticipate.

Take Deepfake as an example. Sophisticated AI programs can now manipulate sounds, images and videos, creating impersonations that are often impossible to distinguish from the original. Deep-learning algorithms can, with surprising accuracy, read human lips, synthetize speech, and to some extent simulate facial expressions. Once released outside of the lab, such simulations could easily be misused with wide-ranging impacts (indeed, this is already happening at a low level). On the eve of an election, Deepfake videos could falsely portray public officials being involved in money-laundering or human rights abuses; public panic could be sowed by videos warning of non-existent epidemics or cyberattacks; forged incidents could potentially lead to international escalation.

The capacity of a range of actors to influence public opinion with misleading simulations could have powerful long-term implications for the UN’s role in peace and security. By eroding the sense of trust and truth between citizens and the state—and indeed amongst states—truly fake news could be deeply corrosive to our global governance system.

AI Reading Us

Second, AI is already connecting and converging with a range of other technologies—including biotech—with significant implications for global security. AI systems around the world are trained to predict various aspects of our daily lives by making sense of massive data sets, such as cities’ traffic patterns, financial markets, consumer behaviour trend data, health records and even our genomes.

These AI technologies are increasingly able to harness our behavioural and biological data in innovative and often manipulative ways, with implications for all of us. For example, the My Friend Cayla smart doll sends voice and emotion data of the children who play with it to the cloud, which led to a US Federal Trade Commission complaint and its ban in Germany. In the US, emotional analysis is already being used in the courtroom to detect remorse in deposition videos. It could soon be part of job interviews to assess candidates’ responses and their fitness for a job.

The ability of AI to intrude upon—and potentially control—private human behaviour has direct implications for the UN’s human rights agenda. New forms of social and bio-control could in fact require a reimagining of the framework currently in place to monitor and implement the Universal Declaration of Human Rights, and will certainly require the multilateral system to better anticipate and understand this quickly emerging field.

AI as a Conflict Theatre

Finally, the ability of AI-driven technologies to influence large populations is of such immediate and overriding value that it is almost certain to be the theatre for future conflicts. There is a very real prospect of a “cyber race” in which powerful nations and large technology platforms enter into open competition for our collective data as the fuel to generate economic, medical and security supremacy across the globe. Forms of “cyber-colonization” are increasingly likely, as powerful states are able to harness AI and biotech together to understand and potentially control other countries’ populations and ecosystems.

Towards Global Governance of AI

Politically, legally and ethically, our societies are not prepared for the deployment of AI. The UN, established many decades before the emergence of these technologies, is in many ways poorly placed to develop the kind of responsible governance that will channel AI’s potential away from these risks and towards our collective safety and wellbeing. In fact, the resurgence of nationalist agendas across the world may point to a dwindling capacity of the multilateral system to play a meaningful role in the global governance of AI. Major corporations and powerful member states may see little value in bringing multilateral approaches to bear on what they consider lucrative and proprietary technologies.

There are, however, some important ways in which the UN can help build the kind of collaborative, transparent networks that may begin to treat our “trust-deficit disorder.” The Secretary-General’s recently-launched High-Level Panel on Digital Cooperation, is already working to build a collaborative partnership with the private sector and establish a common approach to new technologies. Such an initiative could eventually find ways to reward cooperation over competition, and to put in place common commitments to using AI-driven technologies for the public good.

Perhaps the most important challenge for the UN in this context is one of relevance, of re-establishing a sense of trust in the multilateral system. But if the above trends tell us anything, it is that AI-driven technologies are an issue for every individual and every state, and that without collective, collaborative forms of governance, there is a real risk that it will be a force that undermines global stability.
