Bioenergy and the Dairy Sector

California is the largest dairy state in the United States, providing a large share of the country’s milk and dairy products.  Unfortunately, dairies are also California’s largest source of methane emissions, a climate super pollutant.  Dairy manure can, however, be converted to carbon negative energy, eliminating methane emissions and providing negative carbon emissions instead.   According to the California Air Resources Board, investments in dairy digesters, which convert dairy waste to energy,  are the most effective and the most cost-effective of all of the state’s investments in carbon reductions.

California’s dairy cows produce enough waste to generate 550 megawatts of renewable electricity or more than 100 million gallons per year of carbon negative transportation fuels. Biomethane generated from dairy waste is the lowest carbon fuel of any in existence, more than 500 percent lower greenhouse gas emissions than gasoline or diesel.  Dairy waste can also be used to generate flexible generation renewable power, which is critical to complement wind and solar power because it’s available 24/7 and can be stored and used as needed.  In addition to cutting methane emissions and producing renewable energy, converting dairy waste to energy reduces air and water pollution from dairies, cuts odors, and can provide revenue and onsite energy supplies to dairy farms.

Bioenergy Critical to Climate

Bioenergy is critical to slow global warming right away and to reach carbon neutrality by mid-century.  That’s because bioenergy can reduce the most damaging climate pollutants known as Short-Lived Climate Pollutants (SLCPs).  Climate scientists agree that we have less than a decade left to avert catastrophic – and largely irreversible – climate change.  The most effective tool we have – the last lever we have left – is to reduce SLCP emissions.  And bioenergy can do that more effectively than other tools because it cuts methane and black carbon emissions – two of the most damaging SLCPs – from organic waste, including landfills and dairies, agricultural waste, and forest waste or other vegetation removed to reduce wildfire risks.  Bioenergy can also provide carbon negative emissions needed to reach carbon neutrality by mid-century.  And, according to the California Air Resources Board, it provides the most cost-effective of all carbon emissions.

National Academy of Sciences Paper Underscores Need for Bioenergy

Some energy advocates and environmental groups have been claiming that the U.S. can meet all its energy needs with solar, wind and energy storage. The National Academy of Sciences has released a paper that criticizes that view as likely to be dangerously expensive if achievable at all. The NAS paper strongly recommends the inclusion of bioenergy in a low carbon portfolio to provide power that is easily dispatchable (available when needed) and that can be carbon negative.

GNA Releases Report on Ultra Low Emission Trucks

Gladstein Neandross & Associates recently released GameChanger, a groundbreaking report on the potential for ultra-low emission vehicles running on biogas to cut greenhouse gas emissions and air pollution.  Heavy duty trucks using an ultra-low NOx engine that runs on renewable gas can cut toxic air contaminants and particulate matter by more than 90 percent.  When fueled with biogas from dairy waste or food waste that would otherwise have been landfilled, the trucks can cut greenhouse gas emissions by more than 100 percent compared to diesel powered trucks.

E3 Releases Study on Decarbonizing Pipeline Gas

Energy and Environmental Economics (E3) released a study on Decarbonizing Pipeline Gas to Help Meet California’s 2050 Greenhouse Gas Reduction Goal.  The study found the costs of decarbonized gas and electrification to be similar, but the flexibility and operational benefits of decarbonized gas to be beneficial, particularly in some sectors.

The study’s main conclusions are:

  • Decarbonized pipeline gas can help to reduce emissions in sectors that are otherwise difficult to electrify, either for technical or customer-acceptance reasons. These sectors include: (1) certain industrial end uses, such as process heating, (2) heavy duty vehicles (HDVs), and (3) certain residential and commercial end uses, such as cooking, and existing space and water heating.
  • The production of decarbonized gas from electricity could play an important role in integrating variable renewable generation by producing gas when renewables are generating power, and then storing the gas in the pipeline distribution network for when it is needed.
  • A transition to decarbonized pipeline gas would enable continued use of the state’s existing gas pipeline distribution network, eliminating the need for new energy delivery infrastructure to meet 2050 GHG targets, such as dedicated hydrogen pipelines or additional electric transmission and distribution capacity.
  • Pursuit of decarbonized gas technologies would help diversify the technology risk associated with heavy reliance on a limited number of decarbonized energy carriers, and would allow consumers, businesses and policymakers greater flexibility and choice in the transition to a low-carbon energy system.

State of the Sierra Nevada’s Forests

The Sierra Nevada Conservancy, a California state agency, issued this important report on the State of the Sierra Nevada’s Forests, finding that “urgent action is needed in the Sierra Nevada to avoid devastating impacts on California’s environment and economy.”  The report recommends increased forest biomass to energy generation to reduce catastrophic wildfires and air pollution.

BAC Releases Groundbreaking Report on Renewable Gas

See BAC’s groundbreaking report on how to decarbonize California’s gas sector.  The report describes the role of natural gas in California, the potential for renewable gas to generate power and fuels, and the need for a Renewable Gas Standard to cut greenhouse gas emissions, create jobs and increase energy security.   Download BAC Report on Renewable Gas Standard.  The report finds that:

  • California imports more than 90 percent of the natural gas it uses, costing the state thousands of jobs and billions of dollars per year.
  • Natural gas causes more than a quarter of the state’s greenhouse gas emissions and is a significant source of air and water pollution.
  • Organic waste alone can produce enough renewable gas to replace ¾ of all the diesel used by motor vehicles in California or enough electricity to power 2 to 3 million homes.
  • Renewable gas produces two to six times as many jobs per megawatt as fossil fuel gas.
  • Replacing just 10 percent of California’s gas supply with renewable gas would reduce greenhouse gas emissions by tens of millions of metric tons per year, while cutting wildfire, air pollution and landfilling.

Bioenergy 101

California generates 37 million tons of organic waste per year, waste that can be used to generate 2.4 billion gallons of low carbon transportation fuel or 6,000 megawatts of renewable power, more than ten percent of the state’s total transportation fuel or electricity needs. Organic waste can be used to produce the lowest carbon transportation fuel of any kind, cut toxic air pollution from diesel powered trucks, produce renewable power that’s available 24/7,  reduce wildfires and landfilling, create good jobs and instate energy supplies.

Bioenergy and the Forest Sector

California forests provide a critical carbon sink that is quickly going up in smoke.  Wildfire now causes two-thirds of California’s black carbon emissions, a powerful climate pollutant and threat to public health. A single large wildfire can emit as much climate pollution as several million cars and a bad wildfire season can produce as much climate pollution as the state’s entire transportation or energy sector in a year.  Bioenergy is an important tool to reduce wildfire emissions and restore carbon to California’s forests.  Increasing forest biomass power can reduce the devastating impacts of wildfire, protect public health and safety, and provide local jobs and economic development. Forest biomass can provide flexible generation power to meet the state’s renewable electricity goals and can provide low carbon fuels, heating and other energy needs.
