EIA: Renewable diesel increasingly used to meet California’s Low Carbon Fuel Standard; 10.1% of total diesel supplied in 2Q18 ... 15-rd.html
Renewable diesel net supply to California’s fuel market has increased since the state’s Low Carbon Fuel Standard (LCFS) program went into effect in 2011, reaching 100 million gallons during the second quarter of 2018, or 10.1% of the total diesel supplied to California that quarter, according to the US Energy Information Administration (EIA). . . .

As carbon intensity requirements have become progressively more stringent, prices for LCFS credits have increased. Throughout most of the program’s history, LCFS credits averaged lower than $100/metric ton (mt). During 2017, LCFS credits averaged $89/mt, growing to $164/mt through the first 10 months of 2018, suggesting an increasing difficulty for refiners, importers, and wholesalers in meeting annual carbon intensity targets, the EIA said.

The credits generated by renewable diesel producers have some of the lowest carbon intensities of any of the LCFS-approved liquid fuel pathways. The average carbon intensity of renewable diesel, measured in grams of carbon dioxide equivalent per megajoule (gCO2e/MJ), has been about 30 gCO2e/MJ since spring 2016.

Much of this low carbon intensity fuel is made from used cooking oil feedstock. Compared with other liquid transportation fuels, renewable diesel’s carbon intensity is approximately 20 gCO2e/MJ lower than ethanol and about equal to the average carbon intensity of biodiesel. Ultra-low sulfur diesel, which accounts for most of the diesel supplied in California, has a carbon intensity of 102 gCO2e/MJ.

Under the LCFS program, renewable diesel generates a large number of credits relative to other fuels because it has some of the largest lifecycle greenhouse gas reductions compared with other fuels. The total volume of LCFS credits associated with renewable diesel exceeded that of fuel ethanol for the first time in 2018, reaching about 870,000 mt of carbon dioxide equivalent during the second quarter of 2018.

While renewable diesel imports from Singapore remain significant, planned renewable diesel production capacity additions during the next several years have the potential to increase the share of domestic renewable diesel in the California market. A number of LCFS amendments are slated to go into effect in 2019, including an extension of the program to increase the total reduction in carbon intensity to at least 20% by 2030.

Fuel suppliers, airlines partner to provide sustainable jet fuel at SFO ... 2-sfo.html
Shell Aviation and SkyNRG have begun supplying sustainable aviation fuel (SAF) to international airlines KLM, SAS and Finnair at San Francisco Airport (SFO). The fuel is produced by World Energy.

The initial phase of the arrangement aims to pave the way for longer term, more resilient supply chains for sustainable aviation fuels and reduce the carbon emissions of flights from SFO and other airports. Following May’s agreement, Shell Aviation is the first major fuel supplier to support SFO in its ambition to expand the use of sustainable aviation fuel in its operations. . . .

The SAF sourced by SkyNRG from World Energy’s Paramount refinery in Los Angeles is made from used cooking oil, resulting in a fuel that has significantly lower lifecycle carbon emissions than conventional jet fuel. In general, sustainable aviation fuel has a reduction potential of 60-80%, compared to conventional jet fuel.

The SAF is supplied through the existing SFO refuelling infrastructure and can be used by airlines without requiring technical modification to their current fleets.
The comment by Engineer-Poet describes the practical limits of this approach:
Consumption of vegetable oils in the USA 2014-16 was only 38.6 kg/capita. If all of this wound up as WVO (waste vegetable oil) at 7 lb/gallon it would only make 12.2 gallons/capita, or about 3.77 billion gallons (90 million bbl) per year.

2017 US consumption of jet fuel was 1.682 million barrels a day. Converting all US vegetable oil to jet fuel would have fed demand for about 56 days. This is the definition of "cannot scale".

Etihad Airways flies first flight using fuel made in the UAE from plants grown in saltwater ... tihad.html
The Sustainable Bioenergy Research Consortium (SBRC), a non-profit entity established by Masdar Institute that is part of Khalifa University of Science and Technology, announced the world’s first commercial flight using locally produced sustainable fuel on an Etihad Airways Boeing 787 powered by GE’s GEnx-1B engines. (Earlier post.)

The flight from Abu Dhabi to Amsterdam marked a milestone in the development of a clean, alternative aviation fuel to reduce carbon emissions. The initiative also addresses food security in the UAE through the farming of seafood as a core element in the process.

The SBRC partners have been working together to prove the concept of a comprehensive value chain that is centered around the Seawater Energy and Agriculture System (SEAS). This is a synergistic industrial platform that supports the aviation sector, the oil and gas industry, food production and the creation of a new agricultural alternative in the UAE.

Sustainable fuel for the flight was derived from oil in Salicornia plants, which were grown on the two-hectare SEAS farm in Masdar City. The SEAS is the world’s first desert ecosystem designed to produce fuel and food in saltwater. Fish and shrimp raised at the facility provide nutrients for the plants as well as contribute to the UAE’s food production. . . .
Gevo joins SFO consortium to advance sustainable aviation fuel (SAF) ... -gevo.html
Gevo has signed on to a Memorandum of Understanding (MOU) with a group of eight airlines and certain fuel producers to work cooperatively on expanding the use of Sustainable Aviation Fuels at San Francisco International Airport (SFO). (Earlier post.) . . .

SFO is working on a study to identify the necessary supply chain and infrastructure required to make this expansion of SAF at the airport a reality, and is preparing an implementation plan to do so. SFO is positioning for increased interest in the California market for SAF producers and suppliers, given the additional incentives likely to be made available, through a California Air Resources Board ruling allowing the opt-in inclusion of SAF in the Low Carbon Fuel Standard (LCFS). This is the first sub-national government to offer any incentive for the benefits provided by SAF.

The four airlines—United Airlines, Alaska Airlines, American Airlines, and Cathay Pacific—represent nearly 70% of all flights at SFO, while the four fuel producers include SFO’s two primary suppliers, Chevron Corporation and Shell Oil Company along with Neste and LanzaTech, Inc.

Together with SFO Fuel Company, LLC, the Airport’s Fuel Consortium, Gevo and these partners will strive to increase SAF supply globally and at SFO.

Airlines at SFO currently use more than 1 billion gallons of jet fuel annually. If SAF suppliers are able to increase global supply from the current 5 million gallons per year to 500 million gallons per year, the use of SAF could prevent nearly 4.8 million metric tons of greenhouse gas emissions per year—equivalent to taking more than one million cars off the roads. . . .

Increased demand for renewable natural gas from refuse sector ... 1-rng.html
Clean Energy Fuels Corp. announced an increased demand for renewable natural gas (RNG) from the refuse sector, particularly in California, where refuse trucks can be fueled by the very solid waste they haul.

The City of Fresno signed a two-year agreement with Clean Energy for renewable liquified natural gas (RLNG) to power approximately 140 refuse trucks with its Redeem brand RNG for an anticipated annual total of 1.6 million LNG gallons, the equivalent of just over one million GGEs.

Redeem is the first commercially available RNG vehicle fuel. It is derived from capturing biogenic methane that is naturally sourced by the decomposition of dairy and landfill waste. Redeem enables at least 70 percent reduction in carbon emissions when displacing diesel or gasoline, according to California Air Resources Board (CARB) estimates.

The City of Long Beach has entered into a new two-year contract to fuel 77 vehicles with an expected 225,000 GGEs of Redeem, including its 35 LNG refuse trucks.

NASA Services in Montebello has opted to power its growing CNG refuse fleet of 50 vehicles with an approximate 400,000 GGEs of Redeem, while neighboring Arrow Services in La Puente will fuel 30 trucks with an anticipated 250,000 GGEs.

Burrtec in Riverside County has inked a deal to fuel its transfer truck fleet with an anticipated 350,000 GGEs of Redeem from a public access station that Clean Energy operates in Riverside.

Outside of California, the City of Spokane, Wash. has renewed a second option for operations and maintenance, along with an expected 250,000 GGEs of Redeem annually to power 40 waste trucks.
Eni and RenOils to boost collection of used cooking oil for biofuel production ... 1-eni.html
Eni currently makes use of approximately 50% of the used cooking oil available in Italy and, in part thanks to RenOils-member regeneration companies, will extend its capacity to produce high-quality biofuel from this waste in the company’s bio-refinery in Venice, at Porto Marghera, and soon also in Gela.

The goal is to increase collection and proper disposal, since used oils from households are currently wasted almost entirely. Around 75,000 tonnes of waste food oil were collected in 2018, almost exclusively from the food service and industrial sectors, which represent just 25% of oil produced in Italy, which in turn totals around 280,000 tonnes per year.

The majority comes from homes, and goes down the drain for the most part, since most people don’t know that using the sewage network to dispose of cooking oil can have serious consequences for the environment.

As well as clogging domestic drains and the network as a whole, increasing maintenance costs, disposal through the sewage network impairs the correct operation of the purification systems and increases those costs too.

One liter of oil generates up to four kilograms of sewage sludge which then needs to be treated as waste, can arrive at aquifers and make the water undrinkable and pollute surface water, harming the ecosystem, flora and fauna. If it ends up in water, it forms a film that prevents the passage of sunlight, causing huge damage to the environment. . . .
QUT, Mercurius Australia partner on pilot plant to convert sugarcane waste to jet and diesel fuel; REACH ... 1-qut.html
In Australia, QUT researchers and Mercurius Australia are partnering on a pilot plant to prove the economic viability of turning sugarcane waste into either jet and diesel fuel or chemicals that could be used to make plastic soft drink and beer bottles. . . .

REACH (Renewable Acid-hydrolysis Condensation Hydrotreating) technology:
  • Efficiently converts biomass into biofuels and green chemicals without producing CO2 byproduct like fermentation and gasification processes.

    Uses two widely deployed and well understood industrial processing techniques— one from the pulp and paper industry and the other from petroleum refining.

    Creates an intermediate bio-crude product through the use of catalytic hydrolysis (similar to the pulp and paper industry).

    Produces diesel and jet fuel hydrocarbons through a solid-bed-catalytic process analogous to the way the petroleum industry converts crude oil into the various petroleum products on the market today.

    Does not use enzymes or microbes therefore it is not sensitive to feedstock impurities. . . .
Support and funding for this project was provided by the Queensland Government’s A$150-million Jobs and Regional Growth Fund, which helps to facilitate private sector projects that create employment and economic growth opportunities in regional areas. . . .

While the initial focus of the pilot plant is investigating the conversion of biomass into fuel, the technology has the potential to create chemicals that could be used to make polyethylene furanoate (PEF), a completely bio-based polyester used to make bottles, films and fibers as an alternative to Polyethylene terephthalate (PET) plastic produced from fossil fuels. . . .

2019 NTEA Fleet Purchasing Outlook reveals continued strong demand for biodiesel in diesel trucks ... -ntea.html
New research released by NTEA – The Association for the Work Truck Industry confirms that fleets across the country are increasingly relying on biodiesel for their existing and new diesel vehicles. For the third time in four years, surveyed fleets named biodiesel as their top alternative fuel choice both for current use and future interest.

Each year, NTEA conducts a comprehensive Fleet Purchasing Outlook Survey to better understand the commercial vehicle landscape, including interest levels for advanced truck technologies and alternative fuels. Insights from NTEA’s Fleet Purchasing Outlook, provided by fleet professionals across the United States and Canada, give the entire work truck industry perspective on anticipated purchasing intent and areas of greatest interest to fleet managers.

The 2019 NTEA Fleet Purchasing Outlook showed that the majority of fleet survey respondents—76%—anticipate maintaining or increasing use of diesel engine-powered trucks in their fleets, and more than 33% of survey respondents acknowledged currently operating alternative fueled trucks in their fleets.

Survey participants named biodiesel as their top alternative fuel choice at 16%. Additionally, biodiesel was named as their top choice for future interest at 14%. . . .

I stocked up on about 9 to 10 tons of bio fuel for this winter.

Since I burn less than 1 tank of diesel per year in my diesel suburban I try to avoid bio diesel as I would like for it to start in the winter when I need it.
Pretty sure the last time I filled up was early 2018. I know I haven't put any fuel in it this year.
