EPA Moves Closer To Regulating Greenhouse Gas Emissions

April 18, 2009
By: Webmaster 
www.GreenhouseGasEmissions.com

WASHINGTON — In a major reversal of years of government policy regarding Greenhouse Gas Emissions, the Environmental Protection Agency today proposed regulating Greenhouse Gas Emissions to combat and reverse global warming and climate change.

"In both magnitude and probability, climate change is an enormous problem" said E.P.A's Administrator Lisa Jackson in their 130 page report on Greenhouse Gas Emissions. She found that projected levels of Greenhouse Gas Emissions "endanger the public health and welfare of current and future generations."

The finding came two years after the Supreme Court ruled the EPA had the authority to regulate Greenhouse Gas Emissions under the Clean Air Act.

"Renewable Energy Technologies such as; Anaerobic Digesters, Biomethane, Concentrating Solar Power, Geothermal Power Plants are "carbon neutral energy" technologies, and generate no new Greenhouse Gas Emissions.  Power generated from Biomass Gasification power plants, are "carbon negative energy" solutions which actually remove carbon dioxide emissions from the atmosphere, according to the Founder and Chairman of the Institute for Climate Solutions, and the Renewable Energy Institute's Mont Goodell.

How Anaerobic Digesters Work, and

How Anaerobic Digesters Produce Biomethane: 

The Greenest of all Biofuels!

Anaerobic Digesters recover valuable biomethane from animal manure through a process called anaerobic digestion.  

The following information highlights the process of how Anaerobic Digesters work.

Biomethane and Anaerobic Bacteria

Biomethane or "Renewable Natural Gas" is practically the same as is a gas that contains molecules of methane with one atom of carbon and four atoms of hydrogen (CH4 ). It is the major component of the "natural" gas used in many homes for cooking and heating. It is odorless, colorless, and yields about 1,000 British Thermal Units (Btu) [252 kilocalories (kcal)] of heat energy per cubic foot (0.028 cubic meters) when burned. 

Natural gas, or methane, is a fossil fuel - was created hundreds of thousands of years ago by the anaerobic decomposition of organic materials (primarily algae). It is often found in association with oil and coal.

The same types of anaerobic bacteria that produce natural gas also produce biomethane today. Anaerobic bacteria are some of the oldest forms of life on earth. They evolved before the photosynthesis of green plants released large quantities of oxygen into the atmosphere. Anaerobic bacteria break down or "digest" organic material in the absence of oxygen and produce "Biomethane" as a waste product. (Aerobic decomposition, or composting, requires large amounts of oxygen and produces heat.)

Anaerobic decomposition occurs naturally in swamps, water-logged soils and rice fields, deep bodies of water, and in the digestive systems of termites and large animals. Anaerobic processes can be managed in a "digester" (an airtight tank) or a covered lagoon (a pond used to store manure) for waste treatment. The primary benefits of anaerobic digestion are nutrient recycling, waste treatment, and odor control. Except in very large systems, biomethane production is a highly useful but secondary benefit.

Biomethane produced in anaerobic digesters consists of methane (50%–80%), carbon dioxide (20%–50%), and trace levels of other gases such as hydrogen, carbon monoxide, nitrogen, oxygen, and hydrogen sulfide. The relative percentage of these gases in biomethane depends on the feed material and management of the process. When burned, a cubic foot (0.028 cubic meters) of biomethane yields about 10 Btu (2.52 kcal) of heat energy per percentage of methane composition. For example, biomethane composed of 65% methane yields 650 Btu per cubic foot (5,857 kcal/cubic meter).

Anaerobic Digestion

Anaerobic decomposition is a complex process. It occurs in three basic stages as the result of the activity of a variety of microorganisms. Initially, a group of microorganisms converts organic material to a form that a second group of organisms utilizes to form organic acids. Methane-producing (methanogenic) anaerobic bacteria utilize these acids and complete the decomposition process.

A variety of factors affect the rate of digestion and Biomethane production. The most important is temperature. Anaerobic bacteria communities can endure temperatures ranging from below freezing to above 135° Fahrenheit (F) (57.2° Centigrade [C]), but they thrive best at temperatures of about 98°F (36.7°C) (mesophilic) and 130°F (54.4°C) (thermophilic). Bacteria activity, and thus biomethane production, falls off significantly between about 103° and 125°F (39.4° and 51.7°C) and gradually from 95° to 32°F (35° to 0°C).

In the thermophilic range, decomposition and biomethane production occur more rapidly than in the mesophilic range. However, the process is highly sensitive to disturbances, such as changes in feed materials or temperature. While all anaerobic digesters reduce the viability of weed seeds and disease-producing (pathogenic) organisms, the higher temperatures of thermophilic digestion result in more complete destruction. Although anaerobic digesters operated in the mesophilic range must be larger (to accommodate a longer period of decomposition within the tank (hydraulic retention time), the process is less sensitive to upset or change in operating regimen.

To optimize the digestion process, anaerobic digesters must be kept at a consistent temperature, as rapid changes will upset bacterial activity. In most areas of the United States, digestion vessels require some level of insulation and/or heating. Some installations circulate the coolant from their biomethane-powered engines in or around the digester to keep it warm, while others burn part of the biomethane to heat the digester. In a properly designed system, heating generally results in an increase in biomethane production during colder periods. The trade-offs in maintaining optimum digester temperatures to maximize gas production while minimizing expenses are somewhat complex. Studies on digesters in the north-central areas of the country indicate that maximum net biomethane production can occur in anaerobic digesters maintained at temperatures as low as 72°F (22.2°C).

Other factors affect the rate and amount of biomethane output. These include pH, water/solids ratio, carbon/nitrogen ratio, mixing of the digesting material, the particle size of the material being digested, and retention time. Pre-sizing and mixing of the feed material for a uniform consistency allows the bacteria to work more quickly. The pH is self-regulating in most cases. Bicarbonate of soda can be added to maintain a consistent pH; for example, when too much "green" or material high in nitrogen content is added. It may be necessary to add water to the feed material if it is too dry or if the nitrogen content is very high. A carbon/nitrogen ratio of 20/1 to 30/1 is best. Occasional mixing or agitation of the digesting material can aid the digestion process. Antibiotics in livestock feed have been known to kill the anaerobic bacteria in digesters. Complete digestion, and retention times, depend on all of the above factors.

Sewage Sludge or Effluent

The material drawn from the anaerobic digester is called sewage sludge, or effluent. It is rich in nutrients (ammonia, phosphorus, potassium, and more than a dozen trace elements) and is an excellent soil conditioner. It can also be used as a livestock feed additive when dried. Any toxic compounds (pesticides, etc.) that are in the anaerobic digesters' feedstock material may become concentrated in the effluent. Therefore, it is important to test the effluent before using it on a large scale.

Anaerobic Digester Types and Designs

Factors to consider when designing an anaerobic digester system include cost, size, local climate, and the availability and type of organic feedstock material.

Anaerobic digesters can be manufactured from different materials depending on the location, climate and waste to be processed.  These materials include; concrete, steel, brick, or plastic. Anaerobic digesters are also manufactured in a variety of shapes, including; silos, troughs, basins or may also be a pond or lagoon, and may be placed underground or on the surface. All anaerobic digesters system designs incorporate the same basic components:

• A pre-mixing area or tank

• A digester vessel(s)

• A system for using the biogas

• A system for distributing or spreading the effluent (the remaining digested material).

There are Two Basic Types of Anaerobic Digesters; Batch and Continuous

• Batch

Batch-type digesters are the simplest to build. Their operation consists of loading the digester with organic materials and allowing it to digest. The retention time depends on temperature and other factors. Once the digestion is complete, the effluent is removed and the process is repeated.

• Continuous

In a continuous digester, organic material is constantly or regularly fed into the digester. The material moves through the digester either mechanically or by the force of the new feed pushing out digested material. Unlike batch-type digesters, continuous digesters produce biogas without the interruption of loading material and unloading effluent. There are three types of continuous digesters: vertical tank systems, horizontal tank or plug-flow systems, and multiple tank systems.

Proper design, operation, and maintenance of continuous digesters produce a steady and predictable supply of usable biogas. They may be better suited for large-scale operations.

Many livestock operations store the manure they produce in waste lagoons, or ponds. A growing number of these operations are placing floating covers on their lagoons to capture the biogas. They use it to run an engine/generator to produce electricity.

The cost of designing an constructing an anaerobic digester and the associated "balance of plant" can vary widely. Systems can be put together using off-the-shelf materials. There are also a few companies that build system components. Some sophisticated systems have been designed by professionals whose major focus is research, not low cost.

The Economics and Benefits of Anaerobic Digesters

Before you install one or more anaerobic digesters on your farm or ranch, food processing plant, or facility, you should explore its economic value and potential benefits. You will also want to consider an anaerobic digester "feasibility study" that specifically reviews your operation and requirements.

An anaerobic digester usually requires manure from more than 150 large animals to cost effectively generate electricity. The anaerobic digester and associated biogas production can also reduce overall operating costs where costs are high for sewage, agricultural, or animal waste disposal, and the effluent has economic value.

In the United States, the availability of inexpensive fossil fuels has limited the use of digesters solely for biogas production. However, the waste treatment and odor reduction benefits that anaerobic digesters provide are receiving increasing interest, especially for large-scale livestock operations such as dairies, feedlots, and slaughterhouses.

What is Biomethane?

Biomethane is "renewable natural gas" made from organic sources - which starts out as "biogas" but then is cleaned up in a process called "Biogas to Biomethane" which removes the impurities in biogas such as carbon dioxide, siloxanes and hydrogen sulfides (H2S).

"Cleaned-up" and ready for use in an onsite cogeneration or trigeneration power plant, the Biomethane could also be sold to a pipeline company and completely replace the "natural gas" that is typically transported to markets via the vast underground pipeline system.

Biomethane will some day replace the "methane" that is sold by natural gas utility companies.

Biomethane has an unlimited supply, whereas the methane sold by gas companies has a limited supply.  Biomethane is renewable, whereas the methane sold by your gas utility company is not renewable. Biomethane recovery, use and production generates "Greentags" or a "Renewable Energy Credit" for the owners and is GOOD for our environment.

As previously mentioned, Biomethane is "naturally" produced from organic materials as they decay.  Sources of Biomethane include; landfills, POTW's/Wastewaster Treatment Systems, and every tree or agricultural product that is no longer living.  Biomethane is also generated from animal operations where manure can be collected and the Biomethane is generated from anaerobic digesters where the manure decomposes.

Biomethane, after installation of the Biomethane equipment is essentially free, as opposed to buying natural gas, presently costing around $10.00/mmbtu. 

Methanogenesis is the production of CH4 and CO2 by biological processes that are carried out by methanogens.

More About Our Anaerobic Digesters and Biogas Plants

Renewable Energy Ventures provides Renewable Energy Technologies solutions for our energy and environmental problems.  Our goal is building more Pollution Free Power and Carbon free Energy plants so that we can displace fossil fuels, especially fossil fuels from the Middle East, Russia and Venezuela. 

We are leaders in the production of Biogenic Gas or "Biogas" from multiple waste streams utilizing optimum renewable energy technologies such as Anaerobic Digesters.  

In a process we call "Biogas-to-Biomethane" we then clean, treat and condition the Biogas, removing the typical impurities found in Biogas, such as carbon dioxide, hydrogen sulfide and siloxanes, so that the Biomethane can then be used as a fuel we call "Renewable Natural Gas," in any way that natural gas from fossil fuels might be used.

There are Multiple Environmental and Economic Benefits for 
Installing Our Anaerobic Digesters:

Anaerobic digesters generate numerous economic and environmental dividends:

• Generate practically free Biomethane (also referred to as Renewable Biogas or Renewable Natural Gas) from waste streams.  The Biomethane can then be used as fuel for an onsite power plant such as a cogeneration or trigeneration power plant.
  

• Using the free Biomethane onsite to produce "green energy" qualifies your facility for additional revenue streams in the form of a Renewable Energy Credit, Carbon Dioxide Credits and/or other Greenhouse Gas Emissions credits. 
  

• Reduction in biological oxygen demand in wastewater by over 50%
  

• Reduction in nitrogen in wastewater by over 50%
  

• Reduction in phosphorous in wastewater by over 50%
  

• Dramatic and significant reductions of odors, pollution of surface and groundwaters and nutrient runoff from dairy farms (and other Concentrated Animal Feeding Operations), wastewater treatment plants.
  

• Better neighbors.... facilities that have installed Anaerobic Digesters have fewer complaints from their neighbors as a result of the reduction or elimination of odors.

What is Biomass Gasification?

Biomass Gasification is the process in which Synthesis Gas is produced in the Biomass Gasification process. 

The Synthesis Gas is then used like any other fuel, such as natural gas, which is not a renewable fuel.

Biomass Gasification Basics

Biomass fuels such as firewood and agriculture-generated residues and wastes are generally organic. They contain carbon, hydrogen, and oxygen along with some moisture. Under controlled conditions, characterized by low oxygen supply and high temperatures, most biomass materials can be converted into a gaseous fuel known as producer gas, which consists of carbon monoxide, hydrogen, carbon dioxide, methane and nitrogen. This thermo-chemical conversion of solid biomass into gaseous fuel is called biomass gasification. The producer gas so produced has low a calorific value (1000-1200 Kcal/Nm3), but can be burnt with a high efficiency and a good degree of control without emitting smoke. Each kilogram of air-dry biomass (10% moisture content) yields about 2.5 Nm3 of producer gas. In energy terms, the conversion efficiency of the biomass gasification process is in the range of 60%-70%.

Multiple Advantages of Biomass Gasification

Conversion of solid biomass into combustible gas has all the advantages associated with using gaseous and liquid fuels such as clean combustion, compact burning equipment, high thermal efficiency and a good degree of control. In locations, where biomass is already available at reasonable low prices (e.g. rice mills) or in industries using fuel wood, Biomass Gasifiers offer definite economic advantages. Biomass gasification technology is also environment-friendly, because of the firewood savings and reduction in CO2 emissions.

Biomass gasification technology has the potential to replace diesel and other petroleum products in several applications, foreign exchange.

Applications for Biomass Gasification

Thermal applications: cooking, water boiling, steam generation, drying etc.  Motive power applications: Using producer gas as a fuel in IC engines for applications such as water pumping Electricity generation: Using producer gas in dual-fuel mode in diesel engines/as the only fuel in spark ignition engines/in gas turbines.

Biomethane -
the Perfect Renewable Fuel,
and Best of all Renewable Fuels?

As Biomethane is a near perfect fuel, and since Biomethane represents the best of all biofuels in terms of Recycling Carbon, and has the highest Net Energy Balance, and as Biomethane technologies such as Anaerobic Digesters and Biomass Gasification development increases and becomes even more commonplace, one of the fundamental questions is: what is the size of the potential biomass resource supply in the U.S.?

In April 2005, the DOE and the U.S. Department of Agriculture (USDA) co-published a report assessing the potential of the land resources in the U.S. for producing sustainable biomass: Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply. Looking at forestland and agricultural land, the two largest potential biomass sources, this study estimates that the U.S. can sustainably produce up to 1.3 billion tons of biomass feedstock by mid-century. This would be enough feedstock to produce 60 billion gallons of B100 Biodiesel and E100 Ethanol with today's technologies.

This study doesn't address the opportunities for Biomethane production from biomass feedstock or Biomass Gasification technologies. Some recent estimates indicate that Biomethane could replace up to 50% of present natural gas consumption in the U.S. and in some countries, such as Iceland, Biomethane already provides 100% of the natural gas requirements.

There are many assumptions in the Billion Ton Study report that impact these estimates, but we believe the estimates reasonably reflect the potential availability and impact of biomass resources.

Of the total estimated resource, the study suggests that forestlands in the contiguous United States can produce approximately 368 million dry tons annually. This projection includes 52 million dry tons of fuelwood harvested from forests and woodlands, 145 million dry tons of residues from wood processing mills and pulp and paper mills, 47 million dry tons of urban wood residues including construction and demolition debris, 64 million dry tons of residues from logging and site clearing operations, and 60 million dry tons of biomass from fuel treatment operations.

Biomass to Biofuels

By "converting" biomass wastes – such as municipal solid waste, sewage sludge, crop residues, energy crops, and manure – into biofuels, this will resolve the energy, environmental and political problems in an economical and environmentally sound manner - that will produce over one million new jobs.

According to Jeff Seisler, Director of the European Natural Gas Vehicle Association, "Biomethane has an outstanding potential as a multifaceted solution to multifaceted social problems: urban and agricultural waste management, water purification, and clean air. Urban and agricultural waste can be processed into usable methane, as can the sewage during the water purification process. Cleaning and compressing the gas for use in vehicles then provides cleaner air than petroleum-consuming vehicles."

Continuing, Mr. Seisler states about Biomethane; "this environmental 'closed loop waste-to-energy-to-fuel used in vehicles that again truck the next load of waste to the energy processing plants-substitutes fossil fuels with a renewable resource and reduces greenhouse gases 100% as compared to over gasoline vehicles (on a well-to-wheel basis).

According to Peter Boisen Chairman, of ENGVA, "various well respected European research institutes now estimate more than three times better fuel output per hectare of land used than if going for ethanol or biodiesel. Sweden currently has a 51% Biomethane share, and Switzerland 37%. France, Norway, Germany and Austria use smaller amounts for vehicles. Iceland, completely without natural gas, uses 100% biomethane in its NGVs," Boisen says.  Continuing, Boisen adds, "China, India, Korea, the Ukraine, Spain and Italy are other examples of countries now starting up projects where Biomethane will be used as a vehicle fuel." 

"With the energy efficiency of the gas production process at 50% to 70% it's hard to think of a more socially acceptable and economic energy value for the transportation sector," Boisen says.

"Governments need to get out of their liquid fuel paradigm to refocus and balance their policies and communications to support the development of a Biomethane infrastructure. In Europe Biomethane has the potential to replace 20% of the petroleum consumed in the transport sector by 2030."

Thursday, 29 June 2006
Sacramento, California USA and Sweden 

In a ceremony held at the Ministry of the Environment in Stockholm, representatives of the Kingdom of Sweden and the State of California signed an agreement pledging the two governments and their related industries to work together to develop bioenergy, with a particular emphasis on Biomethane. 

“Through a strong working relationship between its industry and government, Sweden is showing how bioenergy can be developed in a cost-effective manner that benefits its economy and environment. We are extremely pleased to have signed this Memorandum of Understanding (MOU) that will provide a basis for intensified collaboration between Swedish and California officials to develop a thriving bioenergy industry in California,” said Joe Desmond, Undersecretary for the California Resources Agency.

In particular, Sweden has been a global leader in terms of converting biowaste, largely agricultural material and residues, into usable Biomethane. This gas is then used to either generate electricity, residential heating, or as a transportation fuel.

More than 8,000 vehicles in Sweden are powered by a combination of natural gas and Biomethane. The vehicles include transit buses, refuse trucks, and more than 10 different models of passenger cars. There are more than 25 Biomethane production facilities in Sweden and 65 filling stations. The Swedish Biomethane industry has been growing at an annual rate of about 20 percent over the last five years.

According to the Swedish Gas Association, more than 50 percent of the methane used to power Sweden’s natural gas vehicles now comes from biological sources, up from 45% last year. Natural gas vehicle sales in Sweden are increasing at the rate of 25% per annum. 

Sweden was motivated to develop its Biomethane industry because it has no natural gas reserves, to more efficiently manage its waste, and to meet its obligations under the Kyoto Accord. Since Biomethane is developed from methane sources that would normally release into the atmosphere, it’s considered one of the most climate friendly fuels. Methane (and Biomethane) is 21 times more reactive as a greenhouse gas than carbon dioxide (CO2). Sweden is currently meetings its objectives and schedule as outlined in the Kyoto accord.

Biomethane is developed by heating up and breaking down biomaterials in an (Anaerobic Digesters) digester. Among other raw materials, Swedish operators feed their Anaerobic Digesters with slaughterhouse waste, swine manure, and even grassy crops. After the materials breakdown over a 20 day period, technology is then used to remove the impurities and produce Biomethane. Once cleaned-up, Biomethane is 98 percent methane and easily meets the Swedish and California pipeline standards.

The Memorandum of Understanding can be accessed on the California Resources Agency Web site: http://resources.ca.gov/press_documents/CaliforniaSwedenBiofuelsMOU.pdf

With Over 27 Years Experience in Anaerobic Digester Design, Engineering and Operations, We are now Building the World's best Anaerobic Digesters. 

Anaerobic Digesters recover valuable and toxic Biomethane from organic materials and prevents the Biomethane - which has a Global Warming Potential that is 21 times more harmful to our climate than Carbon Dioxide Emissions - from entering the atmosphere.  

Biomethane, which we also refer to as "Renewable Natural Gas" is used as a renewable fuel for our cogeneration and trigeneration power plants. Alternatively, we may sell the Biomethane to a customer and transport it to them from our Anaerobic Digesters via natural gas pipelines.

We believe Anaerobic Digesters and Biomethane represent exciting opportunities for generating renewable natural gas and profits - for multiple reasons:

1.  Anaerobic Digesters take an existing liability and waste (Biomethane) and convert it into an asset and " profit generator."

2.  Anaerobic Digesters mitigate and reverse climate change and global warming by preventing Biomethane to escape into the atmosphere, which is one of the major causes of climate change and global warming.  

Of all Greenhouse Gas Emissions, Biomethane is 21 times more harmful to the environment than Carbon Dioxide Emissions.

3.  Anaerobic Digesters are vital for renewable energy production and helping our country's drive for energy independence. 

4.  EVERY wastewater treatment plant as well as ALL Concentrated Animal Feeding Operations (CAFO's) - IN EVERY COUNTRY - will soon be installing Anaerobic Digesters to prevent Biomethane from entering the atmosphere and help reverse climate change as well as for use as a renewable fuel. Or, they will be replacing their existing inefficient and inferior mechanical wastewater treatment plants, with our "Natural Wastewater Treatment" plants! 

5.  The country of Sweden is the global leader in Biomethane production.  Sweden has identified the Biomethane opportunities and is converting biowaste derived from agricultural material and residues into usable Biomethane. The Biomethane is used to generate clean, renewable electricity, residential heating, and also as a transportation fuel. Biomass sources make up 45% of Sweden’s Biomethane.  Sweden's Biomethane industry has been growing at an annual rate of around 20% over the last five years.  Biomethane powers more than 8,000 transit buses, garbage trucks, and 10 different models of passenger cars in Sweden. Sweden now has more than 25 Biomethane production facilities and 65 filling stations. The country believes that since Biomethane is developed from natural, organic sources that would have been released into the atmosphere, that Biomethane is considered one of the most climate-friendly fuels. Biomethane is 98% methane and easily meets the Swedish and California pipeline standards.
