CA Natural Gas Trucks Now Carbon Negative

Cummins Westport has just announced that natural gas vehicles in California have gone carbon negative!!  Natural gas vehicles are increasingly powered by renewable natural gas (RNG) generated from organic waste.  In 2020, those vehicles removed more carbon dioxide from the atmosphere than they emitted — the direct result of the increasing use of RNG.  RNG use is up more than 170% in the past five years, according to new data from California’s Air Resources Board (CARB), while the carbon intensity of natural gas derived from renewable sources continues to drop. RNG is increasingly made using methane captured from dairy and agricultural waste, landfills and wastewater treatment plants. By capturing gases that would otherwise be released into the atmosphere, RNG can provide carbon negative emissions that are critical to achieve carbon neutrality.

Ninety-two percent of all on-road fuel used in natural gas vehicles in California last year was renewable natural gas and much of that RNG was carbon negative.

In addition to their negative greenhouse gas (GHG) emissions, ultra-low NOx natural gas engines perform at levels that are 95 percent below the federal nitrogen oxide (NOx) standard and 98 percent below the federal particulate matter (PM 2.5) standard.   These are enormous benefits for public health as they reduce smog-forming pollution and toxic air contaminants that cause respiratory illnesses, cancer and other health impacts.

According to NGVAmerica, RNG used as a motor fuel in California in 2020 displaced 1.83 million tons of carbon dioxide equivalent (CO2e). To put those numbers into perspective, California RNG motor fuel use:

  • lowered greenhouse gas emissions by the equivalent amount generated by driving the average passenger car 4.6 billion miles
  • eliminated CO2 emissions, equal to 205.7 million gallons of gasoline consumed, or the energy use of 220,118 California homes in one year
  • sequestered the amount of carbon captured by 2.24 million acres of U.S. forests in one year

Raven SR Announces Joint Venture to Build Hydrogen Fueling Hubs Across US

Raven SR LLC, a renewable fuels company, and Hyzon Motors Inc., a leading global supplier of zero-emission hydrogen fuel cell-powered commercial vehicles, today announced a joint venture to build up to 100 hydrogen hubs across the United States and globally. The first hubs will be built in the San Francisco Bay Area and are expected to commission in 2022 before expanding into the rest of the US and globally. At the hubs, which can be built at or near landfills, Raven SR will convert mixed and multiple organic wastes, including municipal solid waste, greenwaste, food waste, medical, paper, etc. into locally produced, renewable hydrogen for Hyzon’s fleet of zero-emission commercial vehicles.

Raven SR’s patented, Steam/CO2 Reformation process enables it to be one of the only combustion-free, waste-to-hydrogen processes in the world. Unlike alternative approaches to waste disposal, such as incineration or gasification, Raven SR’s process involves no combustion, as confirmed by the State of California EPA’s Department of Toxic Substances. This avoids the creation of toxic pollutants and particulates.

Princeton Study Highlights Need for Bioenergy, Renewable Hydrogen

Princeton University has released a groundbreaking study on how the United States can achieve carbon neutrality.  The study finds that bioenergy – especially biomass with carbon capture and storage – and renewable hydrogen will be critical to achieve carbon neutrality.  The study’s main conclusions related to bioenergy are:

  • Biomass plays an especially important role in achieving carbon neutrality because i) it removes CO2  from the atmosphere as it grows and so combustion of hydrocarbon fuels made with biomass carbon results in no net CO2 emissions to the atmosphere, ii) it can be converted into H2  while capturing and permanently sequestering its carbon, resulting in a net negative-emissions fuel, and iii) it can similarly be used to make negative-emissions electricity.
  • Starting in the 2030s, H2  from biomass with capture of CO2  that is permanently sequestered is a highly cost-competitive technology option because of the  high value of the  associated negative emissions; negative-emissions bio electricity is less valued because of abundant low cost of solar and wind electricity.
  • Hydrogen is a key carbon-free intermediate or final fuel.

SoCalGas Announces Zero-Carbon Goal by 2045

SoCalGas has set a goal to achieve net-zero greenhouse gas (GHG) emissions in its operations and energy deliveries by 2045.  The utility’s commitment makes it the largest North American gas distribution utility to set a net-zero target that includes the company’s direct emissions and those generated by its customers. The goal is net zero emissions from SoCalGas trucks, buildings, and pipelines, as well as the fuel it delivers to customers.

SoCalGas supports California’s goal of carbon neutrality and the goals of the Paris Climate Accord, while ensuring that energy remain reliable and affordable for all Californians. No energy company is more dedicated to achieving this than SoCalGas.  SoCalGas’ commitment to net zero 2045 is a natural extension of its decades-long industry leadership.  Since the passage of California’s landmark California’s Global Warming Solutions Act of 2006 (AB 32), SoCalGas’ decarbonization, diversification, and digitalization efforts have supported the reduction of over 7 million metric tons of CO2e below our 1990 levels – the equivalent of removing 1.5 million cars from the road for a year.

San Joaquin Renewables Project Converts Ag Waste to Fuels and Biochar

The Bakersfield Californian ran a front page story on San Joaquin Renewables’ project in MacFarland, Kern County, which will convert agricultural waste to low carbon vehicle fuels and biochar.  The project will provide huge benefits to the San Joaquin Valley, by providing an alternative to open burning of the agricultural waste and replacing diesel in heavy duty trucks.  The project will also provide about 50 good jobs in the County, which suffers high levels of unemployment.  And, it will provide carbon negative emissions because it will avoid black carbon emissions from open burning and diesel use, plus carbon sequestration from the biochar.

LA County to Expand Food Waste Conversion to Vehicle Fuel

The Los Angeles County Sanitation Districts has pioneered the conversion of food waste to biogas at wastewater treatment facilities.  The Sanitation Districts have been converting food waste to biogas for electricity generation for more than six years.  They are now going to expand their conversion capacity and convert additional food waste to low carbon vehicle fuel.  When the expansion is complete, the Sanitation Districts will generate enough biogas to power the County’s wastewater treatment facility in Carson and produce renewable vehicle fuel equivalent to 2,000 gasoline gallons per day.

Projects like this are helping California to slash the most damaging climate pollutants, replace diesel and fossil fuel gas with low carbon and renewable fuels, and help meet state requirements to reduce landfill waste.

CalMatters: CA Needs Bioenergy and Green Hydrogen for Reliability

CalMatters has published an opinion piece by BAC’s Executive Director that highlights the need for bioenergy and green hydrogen to maintain a reliable and renewable power grid.  The piece underscores the importance of bioenergy and green hydrogen to complement solar, wind and batteries, to provide long duration energy storage and flexible generation power, and to provide renewable fuel for microgrids and backup generators.  The piece makes clear that California can have a 100 percent renewably powered grid, but needs both bioenergy and green hydrogen to ensure that power supplies remain reliable.
