First Qantas US-Australia biofuel flight; Carinata feedstock, Honeywell process
http://www.greencarcongress.com/2018/01/20180130-qantas.html

...
Across its lifecycle, using Carinata-derived biofuel can reduce carbon emissions by eighty percent compared to traditional jet fuel. The ten percent biofuel blend used on the flight will therefore see a seven percent reduction in emissions on this route compared to normal operations.
...
Hopefully they can and do use their own fuel to run the farm equipment. But I have to imagine the biggest part of this reduction must be due to the fact that Australia is an oil importer. As a result, fuel grown in Australia will not have to be transported nearly as far as fuel pumped out of the Middle East.

What this link says is that they get around half of their jet and other fuels from Japan andS. Korea http://www.resilience.org/stories/2...esel-jet-fuel-imports-come-south-korea-japan/ I'd think Indonesia/Malaysia would be the source of most of the oil whose refined products they get from Singapore, while the article says most of the Japan/S. Korean oil is sourced from the middle east.

Western Contra Costa Transit Authority switches entire fleet to Neste MY Renewable Diesel
http://www.greencarcongress.com/2018/02/20180214-westcat.html

Western Contra Costa Transit Authority (WestCAT), a public transportation service in California, has switched their entire fleet of 45 heavy duty buses from operating on petroleum diesel to using only Neste MY Renewable Diesel.

  • Following the success of our three-month trial of Neste MY Renewable Diesel, we have now converted our entire diesel fleet to operate on renewable diesel. We originally transitioned to Neste MY in response to our Board’s interest in reducing our environmental footprint. Changing to renewable diesel allowed us to immediately reduce emissions from our entire fleet, rather than making a series of small improvements as we replace vehicles one at a time.

    —said Charles Anderson, General Manager, WestCAT.

WestCAT has also observed significantly cleaner operation of their bus engines and a significant reduction in the maintenance needed for the emissions equipment and internal engine components.

WestCAT serves the cities of Pinole and Hercules, and unincorporated communities along the eastern edge of San Francisco Bay, operating a network of 14 fixed routes. WestCAT operates 365 days a year, serving more than 65,000 residents within a 20 square mile service area, and carries more than 1.3 million passengers annually. . . .

Instead of leveling forests and repurposing food-crop farmland to grow yet another monocrop, I recommend that we install PV panels on rooftops and provide for an equivalent amount of miles to be driven with significantly less environmental damage. What was that ratio again? 1/100 the area needed with PV to drive the same number of miles. No plowing, harvesting, processing. It just sits there for many DECADES making clean BEV fuel from the sun.

In other words, simply put a few PV panels on your roof and drive 12,000 miles/year every year for the next 30 years. Unlike biofuels, this approach works everywhere in the continental US plus Hawaii. Some southern areas can get by with about 4 PV panels and in the Pacific Northwest you might need 8 or 10. If all US homeowners did this (or more) we could replace massive amounts of fossil-fuel consumption.

Where do you live that 4 panels would provide any sort of fuel? Not counting charging losses a 320w 4 panel system would give you 1700kwh here in the south, even at 4 m/kwh that would be 6800 miles. My Leaf averages 3.6 and my Tesla closer to 3 m/kwh. Lets assume the highly optimistic 4 miles/kwh because it makes numbers easy. you'd need 3,000 kwh to drive your 12K miles, that would be a 2.5kW system here in Texas and 8 panels, twice what you think.

I was an off-the-cuff estimate, but here's my math:

- The 235-Wp 60-cell panels on my roof each produce a third of a MWh of electricity each year. If I scale that by 6/5 which is the per-panel ratio of production I see with Tony Williams' system in San Diego versus mine and scale up to 325-Wp panels I come up with a per-panel annual production (AC) of about 550 kWh/year.

- Four of such panels will produce about 2.2 MWh/year.

- We get an efficiency of about 5 miles/kWh in our LEAF. (That's fairly high, but others here report higher numbers.) We know that L2 charging efficiency of the LEAF with the 3.6 kW charger was 91%. Since there is a fixed load of about 300 W for cooling pumps, I expect the efficiency of a 6.0 kW charger is closer to 95%. That gives about 4.75 miles/kWh.

- I'm going to assume the magic of net metering to allow me to use all of the AC energy that I produce on my roof.

2200 kWh * 4.75 miles/kWh = 10,450 miles.

I should have said five panels to cover 12,000 miles (or even 13,000 miles) with current technology.

But your point is taken: It is hot in places like Texas or Arizona, so PV production is likely lower. And of course driving styles and vehicle type do affect consumption. So YMMV.
 
I see people post about 5-6 miles/kwh and I don't even see how that possible unless you never get on the highway.

Neste delivers first batch of 100% renewable propane to European market
http://www.greencarcongress.com/2018/03/20180319neste.html

Neste has started up the world’s first large-scale renewable propane production facility in Rotterdam in the Netherlands. The first cargo of renewable propane has been delivered to SHV Energy, which will market and sell the product to its customers across Europe as BioLPG. Neste’s new facility has a production capacity of 40,000 tonnes per year; SHV Energy will be the exclusive distributor, supplying 160,000 tonnes over four years. (Earlier post.) . . .

Neste’s Rotterdam refinery primarily produces premium-quality Neste MY Renewable Diesel from various waste and residues as well as vegetable oils. The new unit will purify and separate renewable propane from the sidestream gases produced by the refinery.

Propane-rich off-gas is produced during the NExBTL renewable diesel process; the gas is usually recovered during the Stabilization and Recycle stages of the process.

Usually, the propane off-gas from the Recycle section is used in the steam methane reformer (SMR) plant for the production of hydrogen and the propane off-gas from the Stabilization section is used in a natural gas boiler to raise process steam. . . .

Calor introduces Neste BioLPG to the UK market; targeting fully renewable by 2040
http://www.greencarcongress.com/2018/03/20180330-calor.html

. . . On 16 March, SHV Energy received the first delivery of BioLPG (biopropane) from the Neste Biofuels production facility in Rotterdam. (Earlier post.) This represented the start of the first large scale distribution of BioLPG in the world.

Propane-rich off-gas is produced during Neste’s NExBTL renewable diesel process; the gas is usually recovered during the Stabilization and Recycle stages of the process. Usually, the propane off-gas from the Recycle section is used in the steam methane reformer (SMR) plant for the production of hydrogen and the propane off-gas from the Stabilization section is used in a natural gas boiler to raise process steam. The bio-propane production process increases the added value of this sidestream significantly.

BioLPG is Calor’s first renewable product offering that sees the company commit to reducing its carbon footprint and to become fully renewable by 2040. . . .

BioLPG can reduce carbon emissions by up to 88% over conventional LPG depending on the feedstock used, according to the UK government. Modelling by Calor shows that more than 180,000 rural off-gas grid homes could be heated using BioLPG by 2030 if additional domestic sources of supply are developed, helping the government to achieve its carbon emission targets.

The UK government’s Clean Growth Strategy outlines ambitious new policies to phase out the use of high carbon fossil fuels such as heating oil and coal typically used off the gas grid for domestic heat during the 2020s. . . .

The SHV Energy companies Primagaz and Calor will be responsible for marketing and distributing Neste BioLPG within their respective markets. The countries where customers will initially be able to buy BioLPG are: Great Britain, France, Denmark, Sweden, Germany, Ireland, Netherlands and Belgium.

BioLPG is a drop-in replacement for conventional LPG, so consumers can use exactly the same LPG appliances and vehicles that are widely available throughout Europe. However, the biggest environmental gain from the use of this very low carbon, clean fuel is when it replaces solid and liquid fuels such as coal and heating oil. For example, in Europe there are around 40 million households in rural areas beyond the gas grid. Millions of them currently rely on aging heating oil and central heating systems. If 1 million of them switched to using BioLPG, it would save 5 million tonnes of CO2 emissions—that’s the equivalent of taking 2.5 million cars off the road.

Six trucking firms deploy ultra clean near-zero RNG trucks at Ports of Long Beach and Los Angeles
http://www.greencarcongress.com/2018/05/20180508-rng.html

Six trucking firms operating in the Ports of Los Angeles and Long Beach are deploying trucks powered by Cummins Westport (CWI) near-zero ISX12N engines (earlier post), and fueled with Clean Energy Fuels Corp.’s Redeem brand renewable natural gas (RNG) in an effort to reduce emissions and improve air quality in the ports and surrounding communities. . . .

The California Energy Commission and the South Coast Air Quality Management District provided funding for 20 near-zero Class 8 trucks. The Ports of Los Angeles and Long Beach provided funding for two additional near-zero trucks. The first four near-zero trucks have been successfully operating since mid-2017 and an additional four have been operating since February 2018. . . .

The ultra clean CWI engines achieve the lowest emissions of any heavy-duty engine used in any truck in North America, yet deliver diesel caliber performance with reliability and durability.

The US Environmental Protection Agency (USEPA) and California Air Resources Board (CARB) certified these engines in December 2017 at CARB’s optional low-NOx standard of 0.02 g-NOx/bhp-hr—90% lower NOx emissions than the current EPA NOx standard. The new engines were tested as low as 0.01 g-NOx/bhp-hr, achieving virtually zero tailpipe emissions. Factory production of ISX12N engines began in February.

All these trucks will be fueling at Clean Energy’s network of California stations with Redeem fuel, which reduces greenhouse gas (GHG) emissions by 70% versus diesel. RNG is the cleanest fuel for trucking today, with some GHG sources even reducing GHG by over 100%. . . .
Per the Redeem website, the RNG is methane from landfills and farms (not sewage treatment plants?): http://redeem.cleanenergyfuels.com/

I took a tour of our local sewage treatment plant this past weekend (they had an open house), and they both capture methane from sewage for CHP along with a 468kW grid-intertied solar array to run the plant: https://oroloma.org/sewage-treatment/

Port of Seattle announces partnership for sustainable aviation fuels at Sea-Tac Airport; 10% minimum by 2028, 50% by 2050
http://www.greencarcongress.com/2018/05/20180511-seattle.html

The Port of Seattle recently announced today that 13 airlines, including Alaska Airlines, ANA, Delta Air Lines, Horizon Airlines, Lufthansa, Spirit Airlines and more, have agreed to collaborate on a work plan for providing all airlines at Seattle-Tacoma International Airport with access to sustainable aviation fuel (SAF), a low-carbon and sustainably produced biofuel alternative to jet fuel. . . .

Airlines at Sea-Tac Airport will be projected to use about 700 million gallons of jet fuel per year. A 10% reduction would eliminate 70 million gallons of jet fuel, the equivalent of 682,500 metric tons of airlines’ greenhouse gas emissions.

An industry leader in the use of sustainable aviation biofuel, since 2011 Alaska Airlines has flown nearly 80 flights using sustainable aviation biofuel made of used cooking oil, forest residuals and non-edible, sustainable corn. . . .

DOE selects two projects for $3M in funding to advance biofuels, bioenergy, and biobased products
http://www.greencarcongress.com/2018/05/20180510-brdi.html
. . . The DOE selections are:

The University of Tennessee (UT). UT will be developing an integrated biorefinery design that combines the production of liquid fuels and renewable chemicals to verify production of affordable cellulosic ethanol.

Northwestern University (NU). NU will be developing a rapid synthesis of next-generation biofuels and bioproducts from lignocellulosic biomass. The project will employ several strategies to reduce the timeframe of discovering biosynthetic pathways to optimize fuel and chemical production, including bottom-up engineering principles, computational models, and cell-free framework systems.

Both these projects will lower the costs of the production of bio-based fuels, as well as co-products for chemicals and other uses. If successful, both projects will help the Bioenergy Technologies Office to meet its goal of less than $3 per gallon gasoline equivalent for advanced biofuels.

Renewable natural gas produced in California by CR&R flows into SoCalGas pipelines for first time
http://www.greencarcongress.com/2018/07/201807030-socalgas.html

Southern California Gas Co. (SoCalGas) and waste management company CR&R Environmental (CR&R) announced they are now injecting renewable natural gas produced at CR&R’s anaerobic digestion facility in Perris, Calif., into SoCalGas pipelines. This is the first renewable natural gas produced within California to be introduced into SoCalGas’ pipeline system.

Renewable natural gas is a carbon-negative fuel produced from waste that can be used in trucks and buses, to generate electricity, fuel heating systems in home and businesses, and for cooking. The renewable natural gas from CR&R’s digestion facility is used to fuel about 400 of CR&R’s waste hauling trucks.

CR&R is producing renewable natural gas using organic waste collected in Southern California cities’ green waste bins and processed in an anaerobic digester believed to be the largest and most automated in the world. This biogas is upgraded to the same standards and specifications of traditionally-sourced natural gas and then put into a new 1.4-mile section of SoCalGas pipeline. . . .

Renewable natural gas from other states has already begun to clean the air and reduce greenhouse gas emissions in California’s transportation sector, which accounts for more than 80% of smog forming emissions and about 40% of greenhouse gas emissions in the state. The latest generation of natural gas engines for heavy duty vehicles can reduce smog-forming emissions by more than 90%. When fueled with renewable natural gas, they can reduce greenhouse gas emissions by 80% or more. . . .

Skangas supplying liquefied biogas (LBG) to tanker Fure Vinga
http://www.greencarcongress.com/2018/07/20180703-skangas.html

. . . The Swedish LBG was delivered to Furetank’s M/T FURE VINGA from Skangas’ parent company Gasum’s biogas facility in Lidköping. The fueling took place at the port of Gothenburg, transferring the fuel directly from a tanker truck to the ship.

The FURE VINGA was delivered from the ship yard in April this year and is one of two vessels in the company’s fleet powered by liquefied gas. Furetank has been using LNG as fuel since 2015 when the FURE WEST was converted for dual-fuel.

Together with partners Furetank is building five further sister vessels to the FURE VINGA, all of which will be dual-fuel and can be powered by LBG when the fuel is available. The vessels will be trading in North Europe and will benefit from Skangas’ LNG supply network in the region. Skangas is already supporting Furetank’s other LNG-fueled vessels in ports and at sea. . . .

Firstly, biogas is produced through the processing of various types of organic waste. Secondly, the gas is purified and upgraded to approximately 97% methane. This process takes place in Skangas’s parent company Gasum’s biogas facility in Lidköping. The biogas is further being liquefied by cooling it to a temperature of minus 160 °C for transportation by trucks to customers.

Enbridge and City of Toronto to build one of the first renewable natural gas facilities in Ontario
http://www.greencarcongress.com/2018/07/20180723-enbridge.html

Enbridge Gas Distribution and the City of Toronto will build and install equipment that will turn the City’s organic waste (apple cores, egg shells, coffee grounds, etc.) into renewable natural gas. . . .

Expected to be complete in 2019, the project supports the City’s vision of using Toronto’s organic waste to offset greenhouse gas emissions. As an added benefit, the newly created carbon-neutral, renewable natural gas will be injected into the natural gas distribution system to fuel the trucks that picked up the Green Bin waste.

The Ontario Ministry of Energy (Fuels Technical Report) believes that RNG can replace up to 15 per cent of Ontario’s conventional natural gas supply by 2035. Converting fleets, public transit, and heavy-duty vehicles from diesel to natural gas will reduce greenhouse gas emissions by approximately 15%and save up to 40% on fuel costs. Further, vehicles running on RNG are considered net neutral (with respect to emissions. . . .)

. . . Enbridge and the City of Toronto estimate that more than 5 million cubic metres of RNG could be produced each year at this facility. That’s enough to fuel 132 garbage trucks, 90% of the City’s fleet (or heat more than 2,000 homes). . . .

Vista Unified School District (VUSD), a public school district based in San Diego County, California, has switched its fleet of 53 school buses to run on Neste MY Renewable Diesel.

VUSD is the 4th largest school district in San Diego County and comprises 32 schools. VUSD serves more than 23,000 primary to high school students and 2,000 adult education students in Vista, as well as sections of Oceanside, San Marcos, Carlsbad and some unincorporated areas of the San Diego County. . . .

Unlike biodiesel, Neste MY Renewable Diesel is a direct replacement fuel that requires no blending and is compatible with all diesel engines.

Petroleum diesel and biodiesel contain aromatics and impurities that can contaminate oil, foul fuel injectors and clog the DPF filters. Renewable diesel contains nearly zero impurities and burns much cleaner. . . .


EPA approves RFS pathway for sorghum oil as feedstock for bio-diesel or drop-in renewable fuels
http://www.greencarcongress.com/2018/07/20180725-sorghum.html

The US Environmental Protection Agency (EPA) issued a final notice determining biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process, would meet the lifecycle GHG emissions reduction threshold of 50% required for advanced biofuels and biomass-based diesel under the Renewable Fuel Standard (RFS) program.

The analysis considered a scenario where distillers sorghum oil is recovered from distillers grains with solubles (DGS) at dry mill plants that produce biofuel from grain sorghum and where the remaining reduced-oil DGS co-product is used as animal feed. The distillers sorghum oil is then used as a feedstock for conversion into certain biofuels.

Based on this analysis, EPA is adding these pathways to the list of approved renewable fuel production pathways in the RFS regulations. EPA is also amending the RFS regulations by adding a new definition of “distillers sorghum oil,” and replacing existing references to “non-food grade corn oil” with the newly defined term “distillers corn oil. . . .”

No one says that biofuels need to provide a large fraction of our energy (although it would obviously be great if they could), but they can replace liquid fossil fuels when nothing else can (long-range aviation being the most critical). If large-scale sustainable biofuels do come about, they won't compete with edible cropland but will use something like algae grown in ocean 'farms'. Meanwhile, via GCC:

Ocean farms that will compete with fish, which are people food. And the likely places to build "ocean farms" is in the bays and estuaries where much of the productivity is. I don't claim that all production of biofuels will displace people food, only that large scale production will.

Some biofuels don't directly compete: landfill and sewage methane comes to mind, as does byproducts of lumber mills and such. Yet all of these are tiny fractions of the energy used for long range aviation.
