Otherwise known as the methane gas . But is natural gas sustainable? Renewable natural gas is viewed as a carbon neutral way to clean up landfills and keep our cars running. and future generations. In other places, natural gas occurs in the tiny pores (spaces) within some formations of shale, sandstone, and other types of sedimentary rock. Natural gas has been marketed to us as a sort of compromise between renewable and nonrenewable sources of energy, but this isn't the case. Over the long term, DOE expects that hydrogen production from natural gas will be augmented with production from renewable, nuclear, coal (with carbon capture and storage), and other low-carbon, domestic energy resources. Solar power proves its worth as heat wave grips the state Feedstock availability is affected by the seasonal variability of waste production. In 2010, a West Virginia coal mine collapse and a massive oil spill in the Gulf have renewed people's interest in other energy sources, like natural gas. When the supply is high, natural gas prices go down. RNG can be used in place of fossil natural gas, as pipeline-quality gas, compressed natural gas (CNG) or liquefied natural gas . The sheer size of Texas alone in terms of population, commerce and industry, leads to some staggering natural gas consumption to power itself. The following EPA programs work cooperatively with industry stakeholders to reduce or avoid methane emissions by supporting biogas energy projects including those that produce RNG. When it comes to natural gas production, you may notice that some of the same states considered the largest consumers of natural gas are some of the largest producers. Natural gas, like oil, is formed out of decomposed organic matter derived from marine microorganisms deposited over the past few hundred million years. Exploration and reserves, storage, imports and exports, production, prices, sales. If the results from a test well show that a geologic formation has enough natural gas to make a profit, one or more production (or development) wells are drilled. The Renewable Fuel Standard Program (RFS) is run by the EPA Office of Transportation and Air Quality. Innovating methods to produce carbon-negative RNG from dairy cow waste is an integral part of Chevrons portfolio of solutions. They locate the types of geologic formations that are likely to contain natural gas deposits. "Is natural gas renewable?" Natural gas is found deep in the earth's core, further down than oil, so it's complicated to extract and often harms the environment to do so. An Introduction to Renewable Natural Gas (RNG) - Kinder Morgan All rights reserved. The Next Energy Battle: Renewables vs. Natural Gas But we also want to decrease carbon emissions. The offshore wind industry continues to grow as nations look to change Europe's oil and gas hub into a major source of renewable energy. Shifting political will can result in the defunding of programs or the repeal of legislation. At this cost, it is possible to re-process fossil natural gas, used as an energy input into the gasification process, into 5 to 10 times greater quantity of sustainable SNG. Hydrogen is added to the fuel mix during the gasification process, and carbon dioxide is removed by capture from the purge gas "slip stream" syngas clean-up and catalytic methanation stages. A wide range of fuels with an overall biogenic carbon content of 50 to 55% is technically and financially viable. Its potential as a heat source in existing buildings or in industrial applications in particular has seen growing interest in recent years. Is natural gas renewable? - Natural Gas Intelligence Common sources of renewable natural gas (also referred to as biomethane or upgraded biogas) include landfills, animal manure, food scraps and wastewater sludge. To address these questions, WRI's paper walks readers through common approaches, evaluation metrics and considerations by feedstock that they can use to conduct a local assessment. These financial incentives can provide additional economic drivers for project development. Renewable Natural Gas - Avista Biogas is produced from existing waste streams and a variety of renewable and sustainable biomass sources, including animal waste, crop residuals and food waste. Lambert said Metro pursued renewable natural gas because not only is it a growing source in the Houston area that could be tapped for fuel, but the renewable gas projects can also easily be . This is why you will sometimes see the consumer price of natural gas at its highest points in the summer and winter months. Does RNG production solve waste management problems, or yield co-benefits alongside emissions benefits? Some criticism of renewable natural gas as a climate strategy stems from concern that it may "distract" from other vital decarbonization strategies such as electrification and adding renewable generation to the electric grid. All Rights Reserved. Core advantages of SNG include compatibility with existing natural gas infrastructure, higher efficiency that Fisher-Tropsch fuels production and smaller-production scale than other second generation biofuel production systems. [19], In the UK, NNFCC found that any UK bioSNG plant built by 2020 would be highly likely to use "clean woody feedstocks" and that there are several regions with good availability of that source. Chevron works with our partners in the United States to convert methane from cow waste into RNG for use in heavy-duty vehicles. If you want to do your part to protect the environment, we recommend finding ways to reduce your net carbon emissions, like signing up for a clean natural gas plan. Natural gas also occurs with deposits of crude oil, and this natural gas is called associated natural gas. All that manure saved 8 million gallons of oil. Hydrogen Production: Natural Gas Reforming - Department of Energy The existing gas network also allows distribution of gas energy over vast distances at a minimal cost in energy. Clean Energy for Consumers Renewable natural gas combines the environmental benefits of renewables with the reliability of natural gas to meet the 24/7 needs of our customers. The largest consumer of natural gas in the U.S. is Texas. Replacing traditional diesel or gasoline with RNG can significantly reduce emissions of nitrogen oxides and particulate matter, resulting in local air quality benefits. Oil Refiners Pay for Clean Fuel Credits. 2 Stocks That Can Rise. - Barron's Maps by energy source and topic, includes forecast maps. [20][21], In the UK, using anaerobic digestion is growing as a means of producing renewable biogas, with nearly 90 biomethane injection sites built across the country. Installing equipment and connecting pipelines can cost projects millions of dollars up front. Technically, natural gas should be considered partially renewable. How to Choose Renewable Natural Gas (RNG) Partners, Permitting, Contracts & Financing for Renewable Natural Gas (RNG) Projects, Get Ready to Break Ground on Your Renewable Natural Gas (RNG) Project, RNG from Agricultural-Based AD and Biogas Systems, Renewable Natural Gas: Facility Operation Best Practices, Considering Environmental Justice When Designing and Implementing an RNGProject. Overall, the paper finds that renewable natural gas could play a unique and valuable role in state decarbonization efforts. Choosing sustainable energy suppliers allows us to continue living our lives without compromise while knowing that we are opting for the least harmful choice. Estimates suggest that 780-1,400 billion cubic feet (BCF) of biomethane (equivalent to 4-7% of present-day natural gas consumption in the United States) could be produced from sources requiring anaerobic digestion, such as landfills and manure. Renewable natural gas - Wikipedia Natural gas has been taking an increasingly central role in our energy supply over the past decades. Reduce the need for conventional fuel. The renewable natural gas industry is growing quickly, and the growth is expected to accelerate as the country continues to move away from fossil fuels in pursuit of greener alternatives . Renewable natural gas can be produced and distributed via the existing gas grid, making it an attractive means of supplying existing premises with renewable heat and renewable gas energy, while requiring no extra capital outlay of the customer. Financial market analysis and financial data for major energy companies. Currently, we offer our Clean Natural Gas plan for eligible residential and small business customers in Ohio, with more locations coming soon. It accounts for about 30% of the energy used in the United States. 1 As these materials decompose, they produce methane. *RNG is a term of art and there is not at present a standard definition. It is expected the plant is to re-emerge around 2030 when economic conditions may be more favourable, with the possibility of a higher carbon price. Renewable natural gas may also be derived from "dry" organic wastes in the form of agricultural and forestry residues such as corn plants after harvest, grass clippings, tree trimmings and nut shells. A given state or region may very well have practical opportunities for renewable natural gas deployment that yield significant climate benefits. Major cities such as San Francisco, New York and Denver are just a few examples of cities that have proposed or enacted not using natural gas. On the other hand, biogenic methane is sustainable. Finally, market risk due to fluctuating credit and commodity prices leads to uncertain revenue from renewable natural gas sales. Natural gas withdrawn from natural gas or crude oil wells is called wet natural gas because, along with methane, it usually contains NGLsethane, propane, butanes, and pentanesand water vapor. In fact, most biofuel in the United States was obtained from cow manure. Cost benefit studies indicate that large scale 50% biogenic carbon content sustainable SNG can be injected into the high pressure gas transmission grid at a cost of around 65p/therm. Treatment includes removing moisture, carbon dioxide (CO2) and trace level contaminants (including siloxanes, volatile organic compounds, or VOCs, and hydrogen sulfide), as well as reducing the nitrogen and oxygen content. Dry natural gas is sent through pipelines to underground storage fields or to distribution companies and then to consumers. Rather than viewing renewable natural gas as a substitute for other decarbonization strategies, it is important to consider the alternative fuel's comparative advantages and potential to complement other solutions. Idaho's Ada County is one of many regions in the U.S. that are turning to renewable natural gas (RNG), according to KTVB. that has been upgraded for use in place of fossil natural gas. Unfortunately, many of these farms are based in vulnerable communities. NJ landfills methane emissions could fuel new renewable energy This process of capturing landfill gas and converting it to a usable and sustainable product is something that will benefit the entire Treasure Valley and beyond.". Inspire Clean Energy 13 min read category: Clean Energy 101 Is Natural Gas Renewable Or Nonrenewable? If youre interested in doing more for the environment, consider switching to clean natural gas. To minimize any risk of projects doing more harm than good, renewable natural gas should be evaluated case by case. Reports requested by congress or otherwise deemed important. In Europe, this gas is generally called biomethane; in the United States, proponents have rebranded it as "renewable natural gas" (RNG) "to highlight the role that RNG could and should play in displacing meaningful volumes of conventional natural gas," explains Dylan Chase, spokesperson for the Coalition for Renewable Natural Gas, an . View and use pertinent biogas-related tools and resources in EPAs Biogas Toolkit. Natural gas is extracted from wells, and the drilling and transportation in pipelines result in a significant amount of methane leakage. Conversion of biogas into RNG presents technical challenges. Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. [15] However, it was not economically viable, given the prices of natural gas at the time. [25], A company called Divert, which also reduces food waste through donation, says it will use a $1 billion investment from Canadian pipeline operator Enbridge to scaling its existing network of food waste anaerobic digestors to cover all major markets of North America.[26][27]. [8], A biomass to RNG efficiency of 70% can be achieved during the production process. For example, wastewater facilities often burn biogas in a generator to supply heat and power to the facility, and food waste may be diverted to composting or animal feed. The process is called anaerobic digestion. The raw methane is between 45% and 65% pure, not quite ideal for commercial use. It cannot be stored effectively and is nonrenewable, two significant problems. Natural gas drilling and production have considerable effects on the environment. Thus, vehicles can and should be assessed in terms . Lesson plans, science fair experiments, field trips, teacher guide, and career corner. Renewable natural gas reduces greenhouse gas emissions from farms, food waste and landfills, which protects the climate and makes our air cleaner. Anaerobic digestion of organic material. Natural gas wells can be drilled vertically and horizontally into natural gas-bearing formations. Examples of nonrenewable energy sources include coal, oil, nuclear energy and, for the most part, natural gas. A .gov website belongs to an official government organization in the United States. The Sierra Club exposed the hand of SoCalGas in the formation of C4Bes (astroturfing) and so C4Bes curtailed its lobbying activities, although it continued to promote demand for gas. This reality prompted Southern California Gas Company (SoCalGas) to covertly support the creation of a nonprofit: Californians for Balanced Energy Solutions (C4Bes) which then went on to lobby for the gas sector and against the momentum in favor of electrification. If the results of seismic surveys indicate that a site has potential for producing natural gas, an exploratory well is drilled and tested. 'Renewable' natural gas may sound green, but it's not an antidote for It's refined and transferred via pipelines for use. Bacteria break down organic matter in these "wet" wastes and produce methane, carbon dioxide, and other gases and solids through a process referred to as anaerobic digestion. In addition to the tremendous environmental benefits, using RNG as a transportation fuel also offers . They hope it will be a major environmental and economic development. This can affect aquatic life and human sources of drinking water. Renewable natural gas can, one day, help reduce the life cycle carbon intensity of transportation fuels while meeting the worlds growing energy needs. Therefore, it's less than ideal for the environment, both directly and indirectly, due to methane leaks. Learn more about the RFS. Copyright 2023 Green Matters. Renewable energy sourcescome from (usually) naturally occurring elements such as wind, water, sunshine and organic matter. The third-largest user of natural gas is the residential sector. What Are the Biggest Sources of Renewable Natural Gas? Hydrogen formed deep underground by natural processes could be a major new source of untapped carbon-free power-and unlike oil or gas, the supply is virtually unlimited. Editor's note: A previous version of this blog cited a smaller estimate of the number of renewable natural gas facilities in the United States. After all, though capturing and using methane is better than allowing it to escape to the atmosphere, burning the . Understanding Renewable Natural Gas | SoCalGas Furthermore, competing uses can affect feedstock availability, such as the demand for crop residues for soil retention and enhancing soil nutrients. For facilities that are not already required to mitigate such emissions, an RNG project can reduce methane emissions significantly. Once you're a member, you'll rest easy knowing that carbon emissions from your home's natural gas consumption are being neutralized, and you're doing something positive for the planet. Geologists often use seismic surveys on land and in the ocean to find the right places to drill natural gas and oil wells. Sign up for email subcriptions to receive messages about specific EIA products. But the reason why gas companies are promoting RNG is because many plan to mix it with regular natural gas in pipelines, for a "sustainable mix" even though it's really to keep gas as a viable energy source. Carbon capture and sequestration can be added at little additional cost, thereby progressively achieving deeper de-carbonisation of the existing gas and electricity grids at low cost and operational risk. The process of natural gas production can also create leftover contaminated water that needs to be correctly disposed of to prevent the pollution of groundwater and other bodies of water and land in the surrounding areas. Although natural gas is a leading source of energy, it does have its drawbacks. Natural gas has formed naturally beneath the earth's surface and primarily contains methane and other hydrocarbons such as nitrogen and carbon dioxide. After RNG is upgraded, it can then be injected and transported through natural gas pipeline networks and used as a substitute that is virtually indistinguishable from natural gas. This description has been developed by EPAs voluntary programs. Natural gas contains many different compounds. The advantage of a wide range of feedstocks is that much larger quantities of renewable SNG can be produced compared with biogas, with fewer supply chain limitations. Over time, these layers were buried under sand, silt, and rock. First, the drill site has to be located. protect the planet for this Renewable natural gas can also be converted into liquefied natural gas (LNG) for direct use as fuel in transport sector. When it's burned, it releases 25 percent fewer greenhouse gases and pollutants (sulfur, carbon, nitrogen) into the atmosphere than burning oil does. Were working together to provide energy that drives human progress. Renewable natural gas is primarily composed of methane, which emits carbon dioxide when burned as fuel. We're on a mission to transform the way people access clean energy and accelerate a net-zero carbon future.
