This has caused damage to buildings and infrastructure and increased seismic hazards for people living in affected areas.
Shale gas development can have significant economic impacts on state and local economies, depending on various factors such as the scale, location, duration, and regulation of the extraction process. Shale gas development can provide benefits such as lower energy prices, increased employment and income opportunities, and increased investment and innovation in the energy sector. However, shale gas development can also entail costs such as potential negative externalities for the environment and public health. Therefore, policymakers need to weigh the benefits and costs of shale gas development and design appropriate policies and regulations to maximize the net economic impact of this activity.

1. Understanding carbon Capture and storage (CCS):
- What is CCS? Carbon capture and storage involves capturing CO₂ emissions from industrial processes or power plants and then storing them underground in geological formations. The goal is to prevent these emissions from entering the atmosphere and contributing to global warming.
- How does it work? In CCS, CO₂ is captured using technologies like amine scrubbers or membrane separation. Once captured, it is transported via pipelines to suitable storage sites (such as depleted oil and gas reservoirs or saline aquifers) for long-term sequestration.
- Example: The Sleipner project in Norway has successfully stored over one million tons of CO₂ per year since 1996 by injecting it into a saline aquifer beneath the North Sea.
2. Direct Air Capture (DAC):
- What is DAC? Unlike CCS, which captures emissions at the source, DAC directly removes CO₂ from ambient air. It uses specialized sorbents or solvents to selectively absorb CO₂, which is then concentrated and stored.
- Challenges: DAC is energy-intensive and expensive. Innovations are needed to reduce costs and improve efficiency.
- Example: Climeworks, a Swiss startup, operates DAC plants that capture CO₂ from the air and supply it to greenhouses for enhanced plant growth.
3. Bioenergy with Carbon Capture and Storage (BECCS):
- What is BECCS? BECCS combines bioenergy (such as burning sustainably grown biomass) with CCS. The idea is to generate energy while simultaneously removing CO₂ from the atmosphere.
- Perspective: Some experts view BECCS as a crucial negative emissions technology, but others raise concerns about land use, competition with food crops, and sustainability.
- Example: The Drax power station in the UK is piloting BECCS by using wood pellets as fuel and capturing CO₂ emissions.
4. Enhanced Weathering:
- How does it work? Enhanced weathering accelerates natural processes by spreading crushed silicate rocks (such as basalt) on land. These rocks react with CO₂, converting it into stable minerals.
- Benefits: It not only sequesters CO₂ but also improves soil fertility and ocean health.
- Example: Project Vesta aims to test enhanced weathering by spreading olivine-rich sand on beaches, allowing wave action to facilitate CO₂ absorption.
5. Policy and Investment Landscape:
- Government Support: Policymakers worldwide are recognizing the importance of carbon capture. Incentives, subsidies, and regulatory frameworks are being developed to encourage investment.

The Role of CCS Technology - Tackling Greenhouse Gas Emissions with CCS Technology
14.How CCS and renewable energy can work together to achieve net-zero emissions by 2050?[Original Blog]
One of the main challenges of tackling climate change is to reduce greenhouse gas emissions from the energy sector, which accounts for about three-quarters of global emissions. Renewable energy sources, such as solar, wind, hydro, and bioenergy, can provide clean and sustainable electricity and heat, as well as fuels for transport and industry. However, renewable energy alone may not be enough to achieve net-zero emissions by 2050, the target set by the Paris Agreement to limit global warming to 1.5°C. Carbon capture and storage (CCS) is a technology that can complement renewable energy by capturing and storing carbon dioxide (CO2) from fossil fuel power plants and other industrial sources, as well as from bioenergy and hydrogen production. CCS can also enable negative emissions by removing CO2 from the atmosphere through direct air capture or bioenergy with carbon capture and storage (BECCS). In this section, we will explore how CCS and renewable energy can work together to achieve net-zero emissions by 2050, based on the following points:
1. CCS can reduce emissions from hard-to-abate sectors that rely on fossil fuels or produce process emissions. Some sectors, such as cement, steel, chemicals, and aviation, are difficult to decarbonize with renewable energy alone, due to technical, economic, or infrastructural barriers. CCS can capture and store the CO2 emitted from these sectors, either at the point of production or use, or by using low-carbon hydrogen or synthetic fuels derived from fossil fuels with CCS. For example, CCS can capture up to 90% of the CO2 emitted from cement production, which accounts for about 8% of global emissions. CCS can also enable the production of blue hydrogen from natural gas with CO2 capture and storage, which can be used as a low-carbon fuel for transport and industry.
2. CCS can enhance the flexibility and reliability of the power system by balancing variable renewable energy sources. Renewable energy sources, such as solar and wind, are intermittent and depend on weather conditions and seasonal variations. This poses challenges for maintaining the stability and security of the power grid, especially when the share of renewable energy is high. CCS can provide dispatchable and baseload power generation from fossil fuels or bioenergy, which can complement variable renewable energy sources and ensure adequate supply during peak demand or low renewable output periods. For example, CCS-equipped coal and gas plants can ramp up or down their output depending on the availability of solar and wind power.
3. CCS can act as a bridge from fossil fuel reliance to a clean electricity system. Fossil fuels still dominate the global energy mix, accounting for about 80% of primary energy supply in 2020. Transitioning to a net-zero energy system by 2050 will require a rapid and massive deployment of renewable energy sources, as well as energy efficiency measures, electrification of end-use sectors, and behavioral changes. However, this transition may not be feasible or affordable for all countries and regions in the short term, due to various technical, economic, social, and political barriers. CCS can help reduce emissions from existing fossil fuel infrastructure and assets while enabling a gradual and orderly transition to renewable energy sources. For example, CCS can retrofit existing coal and gas plants to extend their lifetimes and avoid stranded assets.
4. CCS can enable negative emissions by removing CO2 from the atmosphere. Even if all sectors achieve net-zero emissions by 2050, some residual emissions may remain due to technical or economic limitations. Moreover, some overshooting of the 1.5°C target may occur before 2050 due to historical and current emissions. Therefore, achieving net-zero emissions by 2050 will likely require negative emissions, which means removing more CO2 from the atmosphere than emitting it. CCS can enable negative emissions by combining direct air capture or bioenergy with CO2 capture and storage. Direct air capture uses chemical processes to extract CO2 from ambient air and store it underground or use it for other purposes. Bioenergy uses biomass from plants or organic waste to produce electricity, heat, or fuels, while capturing and storing the CO2 emitted during combustion or conversion. For example, BECCS can generate both negative emissions and renewable energy by using biomass for power generation with CCS.
CCS and renewable energy are complementary solutions that can help achieve net-zero emissions by 2050. CCS can reduce emissions from hard-to-abate sectors that rely on fossil fuels or produce process emissions; enhance the flexibility and reliability of the power system by balancing variable renewable energy sources; act as a bridge from fossil fuel reliance to a clean electricity system; and enable negative emissions by removing CO2 from the atmosphere. However, CCS is not a silver bullet that can solve the climate crisis alone. It requires significant investments in research, development, demonstration, and deployment, as well as supportive policies, regulations, and incentives, to overcome technical, economic, and social barriers. It also requires careful consideration of the environmental and social impacts of CO2 capture, transport, and storage, such as water use, land use, public acceptance, and safety. Therefore, CCS should be seen as a part of a portfolio of solutions that includes renewable energy sources, energy efficiency measures, electrification of end-use sectors, and behavioral changes. Together, these solutions can create a net-zero energy system that is secure, sustainable, and affordable for all.

15.Introduction to Carbon Sequestration and CCS[Original Blog]
Carbon sequestration is the process of capturing and storing carbon dioxide (CO2) from the atmosphere or from human activities, such as burning fossil fuels, to prevent or reduce its contribution to global warming. Carbon capture and storage (CCS) is a specific type of carbon sequestration that involves capturing CO2 at its source, such as a power plant or an industrial facility, and transporting it to a suitable location where it can be injected and stored underground in geologic formations. CCS is considered a potential option for mitigating greenhouse gas emissions and addressing climate change challenges. In this section, we will explore the following aspects of carbon sequestration and ccs:
1. Why is carbon sequestration and CCS important? Carbon sequestration and CCS can help reduce the amount of CO2 that accumulates in the atmosphere and contributes to the greenhouse effect, which causes global temperatures to rise and affects the Earth's climate system. According to the Intergovernmental Panel on Climate Change (IPCC), limiting global warming to 1.5°C above pre-industrial levels would require a net zero CO2 emission by 2050, which means that any remaining CO2 emissions would need to be balanced by removing CO2 from the atmosphere. Carbon sequestration and CCS can play a role in achieving this goal by capturing and storing CO2 that would otherwise be emitted or by removing CO2 directly from the air.
2. How does carbon sequestration and CCS work? Carbon sequestration and CCS involve three main steps: capture, transport, and storage. Capture is the process of separating CO2 from other gases contained in industrial emissions or ambient air using various technologies, such as chemical absorption, physical adsorption, membrane separation, or cryogenic distillation. Transport is the process of moving the captured CO2 to a suitable storage location using pipelines, trucks, ships, or trains. Storage is the process of injecting the CO2 into deep underground geologic formations, such as depleted oil and gas reservoirs, saline aquifers, or coal seams, where it can be trapped by physical or chemical mechanisms. Alternatively, some captured CO2 can be utilized for various purposes, such as enhanced oil recovery (EOR), which involves injecting CO2 into oil fields to increase oil production; or carbon utilization, which involves converting CO2 into useful products, such as fuels, chemicals, cements, or plastics.
3. What are the benefits and challenges of carbon sequestration and CCS? Carbon sequestration and CCS can offer several benefits for mitigating climate change and enhancing energy security. Some of these benefits are:
- reducing greenhouse gas emissions from existing and new fossil-fuel-based power plants and industrial facilities without requiring major changes in their operations or fuel sources.
- Enabling the use of low-carbon fuels, such as hydrogen or biomass, that can be produced with CCS.
- Providing a potential revenue stream for storing or utilizing CO2, especially with the availability of financial incentives, such as tax credits or carbon pricing schemes.
- creating new jobs and economic opportunities in the fields of engineering, construction, operation, and maintenance of CCS projects.
However, carbon sequestration and CCS also face several technical, economic, environmental, and social challenges that need to be addressed. Some of these challenges are:
- Developing and deploying cost-effective and reliable technologies for capturing, transporting, and storing large amounts of CO2 at different scales and locations.
- Ensuring the safety and permanence of CO2 storage by monitoring and verifying its behavior and performance over long periods of time.
- Minimizing the environmental impacts and risks of CO2 leakage or migration that could affect groundwater quality, soil health, ecosystem services, or human health.
- Gaining public acceptance and trust for CCS projects by addressing concerns about their feasibility, necessity, desirability, and fairness.
16.Challenges and Future Developments in Carbon Sequestration[Original Blog]
Carbon sequestration is the process of capturing and storing carbon dioxide (CO2) from the atmosphere or from industrial sources, such as power plants, cement factories, and steel mills. It is widely considered as a key strategy to mitigate climate change and achieve net-zero emissions by 2050. However, carbon sequestration faces many challenges and uncertainties that need to be addressed and overcome. In this section, we will discuss some of the main challenges and future developments in carbon sequestration, from technical, economic, environmental, social, and policy perspectives.
Some of the challenges and future developments in carbon sequestration are:
1. Reducing the cost and energy consumption of carbon capture. Carbon capture is the first step of carbon sequestration, which involves separating CO2 from other gases in the atmosphere or in industrial flue gases. This step is often the most expensive and energy-intensive part of the whole process, accounting for 70-80% of the total cost. Therefore, developing more efficient and cheaper technologies for carbon capture is crucial to make carbon sequestration more feasible and attractive. Some of the promising technologies include advanced solvents, membranes, sorbents, cryogenic distillation, and chemical looping. For example, a company called Carbon Engineering has developed a direct air capture technology that uses giant fans and chemical reactors to capture CO2 from ambient air at a cost of $94-$232 per ton.
2. Increasing the storage capacity and security of geologic formations. Geologic formations are natural reservoirs that can store CO2 underground for long periods of time. They include depleted oil and gas fields, deep saline aquifers, coal seams, and basalt formations. However, not all geologic formations are suitable for CO2 storage, as they need to have sufficient porosity, permeability, injectivity, and sealing capacity to prevent CO2 leakage. Therefore, finding and characterizing suitable geologic formations is a challenge that requires extensive exploration and monitoring. Moreover, ensuring the long-term security and integrity of CO2 storage is essential to avoid potential risks such as groundwater contamination, seismic activity, land subsidence, and CO2 leakage. Some of the future developments in this area include developing advanced monitoring techniques, such as seismic surveys, tracer tests, and satellite imagery, as well as improving risk assessment and management frameworks.
3. Enhancing the utilization and value of captured CO2. Utilization is the process of converting captured CO2 into useful products or services, such as fuels, chemicals, plastics, building materials, or enhanced oil recovery (EOR). Utilization can provide economic incentives and environmental benefits for carbon sequestration by creating new markets and reducing the demand for fossil fuels. However, utilization also faces some challenges, such as limited market size, high production costs, uncertain life-cycle impacts, and regulatory barriers. Some of the future developments in this area include expanding the range and scale of CO2 utilization products, such as synthetic jet fuels and lithium-ion battery chemicals, as well as developing standards and policies to support CO2 utilization markets.
4. engaging stakeholders and building public acceptance. Stakeholders are individuals or groups that have an interest or influence in carbon sequestration projects, such as governments, industries, communities, NGOs, researchers, and media. Engaging stakeholders is important to ensure the success and sustainability of carbon sequestration projects by addressing their needs, expectations, concerns, and opinions. However, engaging stakeholders can also be challenging due to different perspectives, interests, values, and levels of knowledge among them. Moreover, building public acceptance is essential to overcome social resistance and opposition to carbon sequestration projects by increasing awareness, trust, participation, and benefit-sharing. Some of the future developments in this area include developing effective communication strategies, creating platforms for dialogue and collaboration, and implementing social impact assessments.
These are some of the main challenges and future developments in carbon sequestration that need to be considered and addressed in order to unlock its potential as a climate solution. Carbon sequestration is not a silver bullet that can solve all the problems related to greenhouse gas emissions.

18.Boosting Performance and Preventing Throttling[Original Blog]
One of the most effective ways to overcome CPU throttling is to upgrade your hardware components. By replacing or adding new parts to your system, you can improve the performance, efficiency, and cooling of your CPU and other components. This can help you avoid overheating, power consumption, and thermal throttling issues that may slow down your system. However, hardware upgrades are not always easy, cheap, or compatible with your existing setup. In this section, we will explore some of the pros and cons of different hardware upgrades that can boost your performance and prevent throttling. We will also provide some examples of how these upgrades can affect your system in different scenarios.
Some of the hardware upgrades that can help you defeat CPU throttling are:
1. CPU cooler: A CPU cooler is a device that attaches to your CPU and helps to dissipate the heat generated by the processor. There are two main types of CPU coolers: air coolers and liquid coolers. Air coolers use fans to blow air over a metal heatsink that absorbs the heat from the CPU. Liquid coolers use a pump to circulate a liquid (usually water or a coolant) through a radiator that transfers the heat to the ambient air. Both types of coolers can reduce the temperature of your CPU and prevent it from reaching the thermal limit that triggers throttling. However, they also have some drawbacks. Air coolers can be noisy, bulky, and interfere with other components. Liquid coolers can be expensive, complex, and prone to leaks or pump failures. You also need to consider the compatibility of the cooler with your CPU socket, case size, and airflow.
- Example: If you have a high-end CPU that generates a lot of heat, such as an Intel Core i9 or an AMD Ryzen 9, you may benefit from a liquid cooler that can provide better cooling performance than a stock or air cooler. However, if you have a low-end or mid-range CPU that does not produce much heat, such as an Intel Core i3 or an AMD Ryzen 3, you may not need a liquid cooler and can save money and space by using a stock or air cooler.
2. Thermal paste: Thermal paste is a substance that fills the gaps between the CPU and the cooler. It improves the thermal conductivity and reduces the thermal resistance between the two surfaces. This allows the heat to transfer more efficiently from the CPU to the cooler and lowers the temperature of the processor. Thermal paste can degrade over time and lose its effectiveness, so it is recommended to replace it every few years or whenever you change your CPU or cooler. However, applying thermal paste can be tricky and messy. You need to use the right amount and spread it evenly over the CPU. Too much or too little paste can cause air bubbles, uneven coverage, or spillage, which can affect the cooling performance and damage your components.
- Example: If you notice that your CPU temperature is higher than usual or that your cooler is not working properly, you may need to reapply thermal paste to your CPU. You can use a small pea-sized amount of paste and place it in the center of the CPU. Then, gently press the cooler onto the CPU and secure it with the screws or clips. The pressure will spread the paste evenly over the CPU surface. You can also use a plastic card or a spatula to spread the paste manually, but be careful not to create air bubbles or gaps.

23.A case study of India[Original Blog]
Carbon capture and storage (CCS) is a technology that can reduce greenhouse gas emissions from fossil fuel-based power plants and industries by capturing carbon dioxide (CO2) and storing it in underground geological formations. CCS has been recognized as an important mitigation option in the global efforts to limit global warming to well below 2°C, as agreed in the Paris Agreement. However, CCS deployment has been slow and uneven across the world, with most of the existing and planned projects concentrated in developed countries. Emerging markets, which account for a large share of global CO2 emissions and fossil fuel consumption, face several barriers and opportunities for CCS development. In this section, we will focus on the case of India, which is the third-largest emitter of CO2 and the second-largest consumer of coal in the world. We will examine the following aspects of CCS in India:
1. The drivers and challenges for CCS adoption in India. India has a strong motivation to pursue CCS as a means to balance its economic development, energy security, and climate action goals. India's energy demand is projected to grow rapidly in the coming decades, driven by population growth, urbanization, industrialization, and rising incomes. Coal is expected to remain the dominant source of electricity generation in India, as it is abundant, cheap, and domestically available. However, coal also contributes to high levels of air pollution and CO2 emissions in India, which pose serious threats to public health and the environment. CCS can potentially enable India to continue using coal while reducing its emissions and complying with its nationally determined contributions (NDCs) under the Paris Agreement. India has also expressed interest in exploring the potential of carbon capture, utilization, and storage (CCUS), which involves converting CO2 into useful products such as chemicals, fuels, or building materials. CCUS can offer additional economic and environmental benefits by creating new markets and reducing the demand for fossil fuels.
However, India also faces significant challenges in implementing CCS at scale. Some of the main barriers include:
- High cost and uncertainty: CCS is still an expensive and risky technology that requires large upfront capital investment, operational and maintenance costs, and long-term monitoring and liability. The cost of CCS varies depending on the type of capture technology, the source and purity of CO2, the distance and mode of transport, and the availability and suitability of storage sites. According to a recent study, the levelized cost of electricity (LCOE) for coal-fired power plants with CCS in India ranges from $76/MWh to $115/MWh, compared to $41/MWh to $74/MWh for plants without CCS. The cost of CCUS is also highly dependent on the market price and demand for CO2-derived products, which are uncertain and vary across regions and sectors.
- Lack of policy support and incentives: India does not have a specific policy framework or incentive mechanism for CCS development. There is no carbon pricing or emission trading system in place that could create a market signal for CCS adoption. There is also no clear regulation or guidance on issues such as CO2 ownership, transport, storage, monitoring, verification, reporting, and liability. Moreover, there is limited public awareness and acceptance of CCS as a viable climate solution among policymakers, industry stakeholders, civil society groups, and consumers.
- Technical and institutional capacity gaps: India has limited experience and expertise in designing, constructing, operating, and regulating large-scale CCS projects. There is a need for more research and development (R&D), demonstration and pilot projects, knowledge sharing and collaboration, human resource development, and institutional strengthening to build the technical and institutional capacity for CCS deployment in India. There is also a need for more data collection and assessment of the CO2 sources, sinks, transport options, and utilization potential in India.
- Competition from other low-carbon technologies: India has been pursuing various renewable energy sources such as solar, wind, hydro, biomass, and nuclear as alternatives to fossil fuels for electricity generation. These technologies have become more competitive and attractive in terms of cost, reliability,
And environmental performance than coal with or without CCS. India has set ambitious targets for renewable energy capacity addition under its NDCs and has achieved remarkable progress in recent years. The share of renewable energy (excluding large hydro) in India's total installed power capacity increased from 12% in 2015 to 24% in 2020. The declining cost of renewable energy coupled with the increasing cost of coal may reduce the economic viability and attractiveness of CCS in India.
2. The current status and future prospects of CCS development in India. Despite the challenges mentioned above, India has also taken some steps to explore the potential of CCS as part of its low-carbon development strategy. Some of the notable initiatives include:
- The establishment of a National Carbon Sequestration Assessment Programme (NCSAP) by the Ministry of Environment, Forests
And Climate Change (MoEFCC) in 2007. The NCSAP aims to assess the geological CO2 storage potential in different regions of India through geological mapping,
Drilling,
And modeling. The NCSAP has identified several potential storage sites in sedimentary basins, such as Cambay, Krishna-Godavari, Cauvery, and Assam-Arakan.
- The launch of a National Mission on Carbon Capture and Utilization (NMCCU) by the Ministry of Science and Technology (MoST) in 2019. The NMCCU aims to promote R&D, innovation, and demonstration of CCUS technologies in various sectors, such as power, cement, steel, fertilizer, and chemicals. The NMCCU has identified several priority areas for CCUS development, such as CO2 capture from flue gas and biogas, CO2 conversion into fuels and chemicals, CO2 mineralization into building materials, and CO2 utilization in algae cultivation and biofertilizers.
- The implementation of a few pilot and demonstration projects on CCS and CCUS by various public and private sector entities. Some of the examples are:
- The first pilot project on post-combustion CO2 capture from a coal-fired power plant in India was conducted by the National Thermal Power Corporation (NTPC) at its Dadri power station in Uttar Pradesh in 2017. The project used an amine-based solvent to capture 5 tonnes of CO2 per day from a slipstream of flue gas. The captured CO2 was then used for enhanced oil recovery (EOR) at the Oil and Natural Gas Corporation (ONGC) fields in Gujarat.
- The first industrial-scale project on carbon capture and utilization (CCU) in India was implemented by Carbon Clean Solutions Limited (CCSL), a UK-based company, at the Tuticorin Alkali Chemicals and Fertilizers (TACFL) plant in Tamil Nadu in 2016. The project used a proprietary solvent to capture 60,000 tonnes of CO2 per year from a coal-fired boiler. The captured CO2 was then used to produce baking soda, which is used as a raw material for various products such as glass, detergents, and paper.
- The first pilot project on direct air capture (DAC) of CO2 in India was initiated by the Indian Institute of Technology Delhi (IITD) in collaboration with the University of Iceland and Reykjavik Energy in 2019. The project uses a novel technology called CarbFix to capture CO2 from ambient air using a fan and a filter. The captured CO2 is then dissolved in water and injected into basaltic rocks, where it mineralizes into stable carbonate minerals within two years.
The future prospects of CCS development in India depend on several factors, such as the evolution of the global and national climate policy landscape, the availability and accessibility of financial and technical resources, the development and deployment of cost-effective and reliable CCS technologies, the identification and characterization of suitable CO2 sources and sinks, the creation and enhancement of public awareness and acceptance of CCS, and the establishment and enforcement of clear and consistent regulatory frameworks and incentive mechanisms for CCS. According to some scenarios and projections, India could potentially deploy up to 50 gigawatts (GW) of coal power plants with CCS by 2050, capturing up to 200 million tonnes of CO2 per year. However, this would require significant policy support and investment from both domestic and international sources.
3. The role and potential of international collaboration for CCS development in India. International collaboration can play a vital role in facilitating and accelerating CCS development in India by providing various forms of support, such as:
