E3 study finds low-carbon gas fuels option for meeting Calif GHG reduction goals

January 28, 2015

A new study by Energy Environmental Economics (E3) consulting suggests that low-carbon gas fuels are a viable option for meeting California’s greenhouse gas (GHG) reduction goals and can simultaneously help achieve pollution emission reduction targets.

Low-carbon gas fuels or “decarbonized gas” refers to gaseous fuels with a net-zero, or very low, greenhouse gas impact on the climate. These include fuels such as biogas, hydrogen and renewable synthetic gases produced with low lifecycle GHG emission approaches.

California makes first investments in $100M energy research & development program; also biogas and H2

December 11, 2014

The California Energy Commission approved its first $10 million to fund Electric Program Investment Charge (EPIC) research and development (R&D) projects during its monthly business meeting today. The Commission also approved grants for the operation of a hydrogen fueling station, biofuel production, geothermal exploration and rooftop solar for schools.

EPIC is a multi-year, research investment program focused on electricity-related innovations, finding new energy solutions and bringing clean energy ideas to the marketplace. The program’s 2012-2014 plan calls for investing $330 million between 2014 and 2015 in innovative technologies that provide benefits to electric ratepayers served by Pacific Gas and Electric Co., Southern California Edison, and San Diego Gas & Electric Co. The seven awards approved will fund applied R&D projects that will develop utility-scale renewable energy generation technologies.

California Energy Commission to award up to $3M for advanced biofuel projects

October 28, 2014

The California Energy Commission’s Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP) announced (PON-14-602) the availability of up to $3 million in grant funds for biofuels projects that are in the early/pre-commercial technology development stage. This solicitation is emphasizing transformative technology solutions to significant biofuels industry problems that increase yields, productivity, or cost effectiveness of biofuel production; and/or that target a significant unmet need in California’s biofuels industry.

The ARFVTP has an annual budget of approximately $100 million and provides financial support for projects that increase the use of alternative and renewable fuels and advanced vehicle technologies.

Oberon’s biogas-based DME now eligible for D3 and D5 RINs under the RFS

September 03, 2014

Oberon Fuels Inc., the first company to announce plans to commercialize biogas-based dimethyl ether (DME) fuel production in North America (earlier post), announced that the US Environmental Protection Agency (EPA) has approved Oberon’s biogas-based DME for inclusion under the Renewable Fuel Standard (RFS).

Oberon’s biogas-based DME is now eligible for high-value D3 (cellulosic) and D5 (advanced) renewable identification numbers (RINs) under the RFS. (Earlier post.) The EPA determined that biogas-based DME produced from the Oberon process resulted in an approximate 68% reduction in greenhouse gases when compared to baseline diesel fuel.

California Energy Commission selects 11 advanced biofuels projects for $43.6M in awards

July 25, 2014

The California Energy Commission (CEC) has selected 11 biofuel projects projects—including gasoline substitutes, diesel substitutes and biomethane projects—for $43,633,421 in awards under a grant solicitation released in January for the development of new, or the modification of, existing California-based biofuel production facilities that can sustainably produce low carbon transportation fuels.

The grant solicitation had announced a total of $24 million available for projects funded by the solicitation; however, the Energy Commission, at its sole discretion, reserves the right to increase or reduce the amount of funds available.

EPA qualifies new biogas and electricity pathways for cellulosic biofuel requirement under RFS; defers decision on other proposed pathways

July 03, 2014

In a newly released rule, the US Environmental Protection Agency (EPA) has clarified the number of cellulosic biofuel renewable identification numbers (RINs, earlier post) that may be generated for fuel made with feedstocks of varying cellulosic content; qualified additional fuel pathways to meet the lifecycle greenhouse gas (GHG) reduction requirements for cellulosic biofuel under the National Renewable Fuel Standard (RFS) program; and clarified or amended a number of RFS program regulations that define terms or address registration, record-keeping, and reporting requirements. The final rule also clarifies that EPA considers corn kernel fiber to be a crop residue.

However, the final rule differs in several ways from the Notice of Proposed Rulemaking EPA had issued in June 2013 (earlier post):

ARB: carbon intensity of biomethane from wastewater sludge could be as low as -65.27 g CO2e/MJ

May 22, 2014

The staff of the California Air Resources Board (ARB) staff has posted three new Low Carbon Fuel Standard (LCFS) fuel pathway applications to the LCFS public comments website: one for corn ethanol (from Heartland Corn Products in Minnesota) and one ARB staff-developed pathway (with two scenarios) for the production of biomethane from the mesophilic anaerobic digestion of wastewater sludge at a wastewater treatment plant (WWTP) located at a publicly-owned treatment works (POTW).

Under the LCFS, the baseline CI value for gasoline was 95.86 g CO2e/MJ; for diesel fuel, 94.71 g CO2e/MJ. Staff estimated the carbon intensities (CIs) for biomethane produced under two alternative scenarios; under the first scenario, the CI of biomethane is 10.86 g CO2e/MJ; under the second, the CI is -65.27 g CO2e/MJ—i.e., it generates a credit.

Velocys, Waste Management, NRG Energy and Ventech form JV for small-scale gas-to-liquids plants

March 24, 2014

Velocys plc, a developer of smaller-scale microchannel gas-to-liquids (GTL) technology, has entered a joint venture (JV) with Waste Management, NRG Energy (NRG), and Ventech Engineers International (Ventech) to develop gas-to-liquids (GTL) plants in the United States and other select geographies.

The JV will pursue the development of multiple plants utilizing a combination of renewable biogas (including landfill gas) and natural gas. Waste Management intends to supply renewable gas and, in certain cases, project sites. All four members will work exclusively through the JV to pursue the intended application (GTL using renewable gas, optionally in conjunction with natural gas) in the United States, Canada, United Kingdom and China.
