Gases that trap heat in our atmosphere are called “greenhouse gases”. The rapid accumulation of carbon dioxide (CO2) and other greenhouse gases in the Earth’s atmosphere trap heat, leading to a warming effect. This accumulation leads to increasingly apparent changes in climate: Namely, warmer temperatures, more frequent and intense storms, and more pronounced extremes.  

While limiting our emissions is a critical step, it is not enough. As a society, we must also focus on actively preventing and scrubbing excess carbon from the atmosphere. Scientists have been working on innovative solutions to this challenge, and Carbon Capture and Storage (CCS) is one such solution that can make a significant impact. 

What Is Carbon Capture & Sequestration (CCS)?

How can we reduce atmospheric carbon dioxide greenhouse gases and tackle global warming at the source? The answer is CCS, or Carbon Capture and Storage/Sequestration. 

CCS helps reduce greenhouse warming through the capture and removal of carbon dioxide from the atmosphere. CCS is not a novel idea: the earth’s ecosystems have been capturing and storing carbon for millions of years in natural cycles. When plants use photosynthesis to convert CO2 to oxygen, or marine phytoplankton absorbs CO2 from the atmosphere, they participate in a process called Biological Carbon Capture and Storage.  

However, thanks to human technological advances, Geologic Carbon Capture and Storage has become a standard practice across many industries in reducing atmospheric carbon dioxide levels. During capture, CO2 is separated from other gases to purify it.  There are several capture methods in use depending on the emissions source, which have been proven effective over many years of using carbon in manufacturing and industrial processes. 

Once pure carbon is captured, it can be utilized in industrial products and excess carbon can be stored safely and permanently deep underground in dense rock formations. In fact, human-engineered CCS has been safely employed to contain carbon emissions for over fifty years. As a proven method to help reduce global emissions, the scientific community agrees that CCS is an essential component of the solution to the climate crisis. 

Did you know? Carbon capture is used every day across many fields vital to our economy, including cement, steel, fertilizers, power generation, natural gas processing. And, it can be used in the production of clean hydrogen – for use in energy storage and hydrogen fuel cells, for example.  

CCS: A 3-Step Process for Clean Air

CCS is typically used in an industrial setting, where CO2 is often produced as a by-product of steel or cement production or from energy-related sources such as power plants or natural gas processing facilities.  

The concept of CCS is relatively simple, involving the following three steps:  

1. Capture: CO2 produced by industrial or energy-related activities is separate from other gases to purify and capture it.
2. Transport: Captured CO2 is compressed for storage. Most capture and storage is done near the site, but captured CO2 can also be transported via ship, trucks, or pipeline to the storage location.
3. Storage: CO2 is stored in rock formations for permanent storage. Sequestration locations are always located at a depth of at least a kilometer underground. Some repurpose depleted oil and gas reservoirs, while many use underwater saline aquifers.

What Are Pre-Combustion and Post-Combustion Carbon Capture?

Multiple techniques are required to mitigate the impact of greenhouse gases, and there are two basic forms of Capture: 

• Point-Source Capture – A large emissions source, like an industrial facility, is equipped with technology to capture and store CO2 at the source, preventing it from being emitted 
• Direct-Air Capture (DAC) – Removal of historical CO2 already in the atmosphere

What Are the Primary Capture Methods?

There are two paths to capturing these gases: pre-combustion capture (capturing CO2 before the gas is burned as fuel to produce electricity) and post-combustion capture (capturing excess CO2 after the fuel has been burned to produce energy).

What Happens During Carbon Transport?

When CO2 needs to be transported, it usually goes through a process to remove liquid water before transport.  For short distances, pipelines carry CO2 as a gas, but for long distances the gas is compressed to a dense fluid, which has less volume and is easier to transport. For very long distances (such as shipping to international markets) CO2 is liquified for transport by ship, but this is not as common.

What are the risks to CO2 leaking from CO2 pipelines and is there research on it?

Carbon dioxide is much safer to transport than many other substances because it does not form flammable or explosive mixtures with air, like oil and gas do. And in the event of leaks, CO2 is non-toxic to humans or wildlife when mixed in the air, except in a highly unlikely event where very CO2 is released very quickly, in high amounts, without moving air. Thankfully, industries employ a variety of safety measures, such as an auto shut-off function when a leak is detected in a pipeline, making these scenarios highly unlikely. CO2 pipelines, and other transportation methods, are safe and closely managed under strict international standards. For example, in the US CO2 pipeline safety is regulated by the federal Pipeline and Hazardous Materials Safety Administration (PHMSA) and CO2 pipeline safety data is publicly reported by PHMSA. Thanks to our mature industrial environment in America, there is significant experience with CO2 pipeline development and operation on land and under the sea. There are around 50 CO2 pipelines currently operating in the US covering over 5,000 miles, which transport approximately 70 million tonnes of CO2 every year. 

Is CCS a Long-Term Solution?

In the United States alone, potential carbon storage sites exist in abundance. In fact, in 2013, the USGS released a nationwide assessment of geological carbon sequestration to estimate U.S. carbon storage potential. The evaluation found that in this country alone, there is enough space to store approximately 3,000 metric gigatons of CO2.  

For context, in the 45 years that CCS technologies have been used commercially, 200 million tons of CO2 have been stored in geological reservoirs in the U.S. This means that in 45 years, we have used only 0.0067% of the storage space we have at our disposal: we haven’t even scratched the surface of this technology’s potential.  

With abundant space for carbon storage below ground, CCS is considered a long-term solution to reduce the impact of atmospheric carbon dioxide. As geologic repurposed carbon reservoirs have existed for millennia as natural hydrocarbon deposits, they will continue to do so for years to come.

According to the Intergovernmental Panel on Climate Change (IPCC), CO2 stored in appropriately selected and managed geological reservoirs is 99% likely to remain there for over 1,000 years. 

Is CCS Safe?

CCS has proven itself over the past 45 years of operation to be safe and effective in negating the effects of climate change as a highly-regulated and reliable means of removing carbon from the atmosphere. 

In the words of the Global CCS Institute, “All components of CCS are proven technologies that have been used for decades at a commercial scale. Indeed, CCS technology is being used worldwide in different ways and is already cutting greenhouse gas emissions.”

CCS and Sustainable Energy Production

For decades to come, natural gas will continue to play an indispensable role in meeting global energy needs. However, the global demand for natural gas is not a reason for the industry to overlook its environmental responsibilities.  

All over the world, we are beginning to see the impact of global warming. And now, more than ever, we must each take responsibility to create a better future for ourselves and our children.

Understanding the Paris Climate Agreement

Adopted on December 12, 2015, at the United Nations Climate Change Conference (COP21) in Paris, France, the Paris Agreement is a legally binding international treaty that unites 195 parties to combat climate change. Built on the foundation of the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol, the goal of the agreement is to reduce global greenhouse gas emissions and address climate change. The primary objective is to restrict the global average temperature well below 2°C above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5°C, thus mitigating climate impacts.

The Paris Agreement comprises:

• Nationally Determined Contributions (NDCs) from each country, setting voluntary and nationally determined targets for emissions reductions
• Worldwide cooperation and financial support mechanisms
• Capacity-building and technology development to assist developing nations in addressing climate change challenges

This dynamic framework mobilizes resources and expedites efforts to combat climate change.

Origin and Development

The Paris Agreement’s roots can be traced back to the United Nations Framework Convention on Climate Change (UNFCCC), established in 1992 as the main international agreement on climate action. Adopted in 1997, the Kyoto Protocol marked another milestone by setting binding emissions reduction targets exclusively for developed countries. However, its efficacy was limited due to the non-participation of major emitters like the United States, China, and India.

During COP 17 in Durban, South Africa, a turning point was reached when delegates agreed to formulate a comprehensive climate treaty by 2015, mandating all major emitters to reduce their global carbon emissions and greenhouse gas emissions. This paved the way for the Paris Agreement, which was opened for signature on April 22, 2016, and entered into force on November 4, 2016, after being ratified by world leaders from various countries.

Goals and Objectives

The post How Much Wind Power Does Texas Generate? appeared first on BKV Energy.

Out of all the states, Texas is the leading producer of natural gas in the US (26% of total production), with over 230 trillion cubic feet of natural gas reserves. Natural gas accounts for more than 40% of the state’s total energy consumption, employs more than 300,000 people, and generates billions of dollars in revenue every year. 

But what is natural gas energy? And how does it work? Let’s find out.

What is natural gas energy, and why it’s important for sustainability

Natural gas is a naturally occurring gas composed primarily of methane but also contains other gasses such as ethane, propane, butane, and nitrogen. It’s found in underground reservoirs, often associated with oil deposits. 

Natural gas has emerged as a significant player in the global energy landscape, offering a cleaner-burning alternative to traditional fossil fuels thanks to its abundant availability, relatively low carbon emissions, and versatility.

The emergence of natural gas as a primary energy source

Natural gas has become an important primary energy source thanks to the discovery of vast natural gas reserves, advancements in extraction technologies, and increasing environmental concerns that have contributed to its rise. 

Today, natural gas is an integral part of the global energy mix, offering a transition away from more carbon-intensive fossil fuels like coal and oil.

The composition and properties of natural gas

Natural gas is a type of fossil fuel that contains various compounds. The primary component of natural gas is methane (CH4), which is made up of one carbon atom and four hydrogen atoms. 

Additionally, natural gas includes smaller amounts of natural gas liquids (NGLs) and non-hydrocarbon gasses like carbon dioxide and water vapor. Natural gas is used as a fuel and plays a role in the production of materials and chemicals. 

How does natural gas energy production and extraction work?

The properties of natural gas (including its high energy content, clean-burning nature, and relatively lower carbon emissions compared to other fossil fuels) make it an attractive choice for power generation, heating, and industrial processes. To harness natural gas as an energy source, it undergoes production and extraction processes.

Natural gas reserves around the world

Natural gas reserves are distributed across the globe, with significant deposits found in various regions. The world’s natural gas reserves are concentrated in a few countries. Russia, Iran, and Qatar have the largest reserves, accounting for about 50% of the world’s total. The United States, United Arab Emirates, Venezuela, Saudi Arabia, Nigeria, and Algeria also have significant reserves.

Russia has natural gas reserves of around 38.6 trillion cubic feet, followed by Iran at 32.1 trillion cubic feet and Qatar at 24.7 trillion cubic feet. The US has the fifth largest natural gas reserves in the world, at around 12.9 trillion cubic feet. 

Methods and technologies in natural gas extraction

Millions to hundreds of millions of years ago, the remains of plants and animals, including diatoms, accumulated in thick layers on the Earth’s surface and ocean floors. Over time, these layers became buried under sand, silt, and rock. Through pressure and heat, some of the carbon and hydrogen-rich material transformed into coal, some into oil (petroleum), and some into natural gas.

Where can you find natural gas?

Natural gas can be found in different locations. In certain areas, it moved into large cracks and spaces between layers of rock, known as conventional natural gas. In other cases, natural gas occurs within the tiny pores of shale, sandstone, and other 

sedimentary rock formations, referred to as shale gas or tight gas, which is considered unconventional natural gas. 

Natural gas is also associated with crude oil deposits, and this type of natural gas is called associated natural gas. It can be found on land, offshore, and deep under the ocean floor. Natural gas found in coal deposits is known as coalbed methane.

To find natural gas, geologists study the structure and processes of the Earth. They identify geologic formations that are likely to contain natural gas deposits. Seismic surveys, conducted on land and in the ocean, help locate the right places to drill natural gas wells. 

These surveys create and measure seismic waves to gather information about the rock formations below the surface. If a site shows potential for producing natural gas, an exploratory well is drilled and tested to determine the quantity and quality of the natural gas resource.

How Is natural gas located and extracted?

When natural gas is found and deemed economically viable, one or more production wells are drilled. In conventional natural gas deposits, the gas flows easily up through the wells to the surface. 

However, in some countries, including the United States, shale gas and other sedimentary rock formations are accessed through hydraulic fracturing or fracking. This process involves injecting water, chemicals, and sand at high pressure to break up the rock formation, releasing the natural gas. The gas is then collected in gathering pipelines and sent to processing plants.

How is natural gas processed?

Natural gas undergoes processing before It’s sold and consumed. Wet natural gas, which is withdrawn from wells, contains methane along with natural gas liquids (NGLs) and water vapor. At processing plants, water vapor and non-hydrocarbon compounds are removed, and NGLs are separated and sold separately. The remaining natural gas, called dry, consumer-grade, or pipeline-quality natural gas, is sent through pipelines for storage or distribution to consumers. Odorants are added to natural gas pipelines to help detect leaks. In cases where natural gas pipelines are unavailable, associated natural gas may be reinjected into oil wells, vented, or burned.

The majority of natural gas consumed in the United States is produced domestically, with some imports from Canada and Mexico. Additionally, a small amount of natural gas is imported in liquefied form (liquefied natural gas or LNG).

Environmental and social impacts of natural gas production

According to the US Energy Information Administration, natural gas emits about 49% less CO2 than coal and about 30% less CO2 than oil. But while natural gas is a cleaner-burning fuel compared to coal and oil, its production and extraction can still have environmental and social impacts. 

Methane emissions during production and transportation, water usage and contamination risks, habitat disruption, and community concerns are some of the environmental and social challenges associated with natural gas production. 

The good news is that the CO2 emissions from natural gas can be reduced by using technologies such as carbon capture and storage.

Natural gas vehicles produce lower emissions compared to gasoline or diesel-powered vehicles, which contributes to reduced air pollution and greenhouse gas emissions. They are also more fuel-efficient, which can save money on fuel costs. In addition, natural gas-powered vehicles are quieter than diesel-powered vehicles, which can reduce noise pollution.

Amtrak operates a fleet of natural gas-powered locomotives that are used to pull passenger trains on a variety of routes across the country, while PG&E operates a fleet of natural gas-powered buses that are used to provide public transportation in California.

Natural gas-powered trains and buses offer a number of advantages over traditional diesel-powered vehicles. They produce fewer emissions, which can help to improve air quality. 

Feedstock in various chemical industries

Natural gas contains hydrocarbons that can be used as raw materials for producing various chemicals and materials and serve as a fundamental resource for the production of plastics, fertilizers, pharmaceuticals, and other essential products. 

The advantages of natural gas energy

Natural gas consumption is growing at an average rate of 2.1% per year in the United States as more and more Americans discover its benefits, which include: 

Lower environmental impact compared to other fossil fuels

Compared to other fossil fuels like coal and oil, natural gas has a lower environmental impact. When burned for power generation, natural gas produces fewer greenhouse gas emissions, including carbon dioxide (CO2) and air pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx). It helps to reduce air pollution and mitigate the effects of climate change. Natural gas emits about 49% less carbon dioxide (CO2) than coal and about 30% less CO2 than oil.

Power generation efficiency and economic viability

Natural gas power plants are highly efficient in converting fuel into electricity. They have a higher energy conversion rate compared to coal-fired power plants, resulting in less wasted energy. The efficiency of natural gas power generation helps in reducing fuel consumption and operating costs, making it an economically viable option.

Versatility of applications beyond power generation

Natural gas is a versatile energy source with various applications beyond power generation. It’s widely used for heating homes, buildings, and industrial processes. It’s also utilized as a fuel for cooking, water heating, and even in some transportation sectors as an alternative fuel.

The challenges and controversies surrounding natural gas

While natural gas offers advantages, it also faces challenges and controversies that need to be addressed. 

Environmental concerns: methane leaks and hydraulic fracturing

One of the primary environmental concerns associated with natural gas is methane leaks. Methane is a potent greenhouse gas, and its release during natural gas production and distribution can contribute to climate change. The extraction method of hydraulic fracturing, or fracking, has raised concerns about water contamination and potential damage to ecosystems.

Geopolitics and energy security

The reliance on natural gas from specific regions can create geopolitical challenges and energy security issues. Countries heavily dependent on natural gas imports may face vulnerability to supply disruptions or price fluctuations. Diversification of energy sources and development of domestic resources can help mitigate these risks.

The future role of natural gas in a decarbonized energy system

While natural gas produces fewer emissions compared to other fossil fuels, It’s still a carbon-intensive energy source. The challenge lies in balancing the need for energy security with the goal of reducing greenhouse gas emissions and achieving a sustainable energy future.

Are there any emerging technologies and innovations in the natural gas industry?

The natural gas industry is continuously exploring new technologies and innovations to address environmental concerns and enhance efficiency. Let’s explore some notable advancements:

Renewable natural gas and other clean gas alternatives

Renewable natural gas (RNG), also known as biomethane, is produced from organic waste sources such as landfills, wastewater treatment plants, and agricultural waste. It offers a cleaner and more sustainable alternative to conventional natural gas. Research is underway to explore other clean gas alternatives, such as hydrogen produced from renewable sources, to further reduce carbon emissions.

Carbon capture, use, and storage in natural gas power plants

Carbon capture, use, and storage (CCUS) technologies aim to capture carbon dioxide emissions from natural gas power plants and store them underground or repurpose them for industrial use. CCUS has the potential to significantly reduce greenhouse gas emissions associated with natural gas power generation.
