^ Not sure why they are discounting batteries and fuel cells. A container ship has huge economies of scale when it comes to fuel storage at other than ambient temperature. You can't put a half meter of insulation around a fuel tank or battery pack in a car and it would be difficult to do that in a locomotive, but there is plenty of space in a ship. That opens up the possibility of a liquid hydrogen tank with minimal boil off losses, or a bank of energy-dense sodium-sulfur batteries that need to be kept at 300°C.

LanzaTech moving forward on scale-up of sustainable aviation fuels in US and Japan
https://www.greencarcongress.com/2019/1 ... atech.html


LanzaTech continues to make strides in scaling up its alcohol-to-jet (ATJ) platform. Commercialization of the ATJ process has been years in the making, starting with the partnership between LanzaTech and the US Energy Department’s Pacific Northwest National Laboratory. PNNL developed a unique catalytic process to upgrade ethanol to alcohol-to-jet synthetic paraffinic kerosene (ATJ-SPK) which LanzaTech took from the lab to pilot scale.

After initial scale-up, qualification by ASTM and the first commercial flight with Virgin Atlantic, sustainable aviation fuel (SAF) made from captured pollution is ready for full-scale demonstration and commercialization.

The US Department of Energy (DOE) is in the negotiation stage with LanzaTech for a $14 million investment in a demonstration-scale integrated biorefinery at LanzaTech’s Freedom Pines site in Soperton, Georgia, according to Michael Berube, Acting Deputy Assistant Secretary for Transportation in the Office of Energy Efficiency and Renewable Energy of the DOE. . . .

LanzaTech’s process can use any source of sustainable ethanol for jet fuel production, including ethanol made from recycled pollution. LanzaTech’s first commercial plant in China has produced more than 10 million gallons of ethanol from recycled steel mill emissions to date.

The flexibility of the technology to utilize a variety of local waste feedstocks attracted the attention of All Nippon Airways (ANA), Japan’s largest 5-Star airline for seven consecutive years, resulting in an offtake agreement with LanzaTech signed earlier this year, allowing ANA to purchase sustainable aviation fuel from LanzaTech’s process.

Following on from this agreement, ANA, strategic investor in LanzaTech, Mitsui & Co., and JXTG Energy have been selected by the New Energy and Industrial Technology Development Organization (NEDO) to conduct a feasibility study on scaling the LanzaTech ATJ (alcohol-to-jet) platform in Japan. Together the partners will establish a sustainable domestic supply chain for ATJ, key to achieving full commercial deployment in Japan.

ANA and Mitsui & Co. kicked off the project by conducting a Boeing 777-300ER ferry flight using sustainable aviation fuel made from recycled carbon on 30 October 2019. As the fuel producer, LanzaTech worked closely with all partners, advising how best to transport and blend the fuel for loading on the aircraft. . . .

Gevo enters into a fuel sales agreement with SAS for sustainable aviation fuel
https://www.greencarcongress.com/2019/1 ... -gevo.html


Gevo, Inc. signed a Fuel Sales Agreement with Scandinavian Airline System SAS) to produce and supply sustainable aviation fuel (SAF) for use and distribution in low-carbon fuel regions of the United States.

With the finalization of this new supply contract, Gevo will supply SAF to SAS from Gevo’s expanded Luverne, Minnesota plant, which is expected to be constructed over the next several years.

For every gallon of SAF produced, Gevo also produces approximately 10 pounds of protein that goes into the food supply chain and can sequester up to 2 pounds of carbon dioxide as carbon into the soil, making it one of the only renewable jet fuel producers to produce both food and fuel while sequestering carbon dioxide and lowering the GHG emissions as compared to traditional fossil-based jet fuel. . . .

Gevo uses low-carbon renewable resource-based carbohydrates as raw materials and is developing renewable electricity and renewable natural gas for the energy of production processes resulting in low-carbon fuels with reduced carbon intensity (the level of greenhouse gas emissions compared to standard petroleum) fossil-based fuels across their lifecycle. Gevo’s products deliver the technical performance expected of traditional fossil-based fuels in infrastructure and engines, but significantly reduce greenhouse gas emissions.

In addition to addressing the problems of fuels, Gevo’s technology also enables certain plastics, such as polyester, to be made with more sustainable ingredients. Gevo’s ability to penetrate the growing low-carbon fuels market depends on the price of oil and the value of abating carbon emissions, which would otherwise increase greenhouse gas emissions. . . .

Bombardier using Gevo’s sustainable aviation fuel for new aircraft deliveries in Canada
https://www.greencarcongress.com/2019/1 ... vosaf.html

Avfuel is providing Bombardier with an inaugural shipment of sustainable aviation fuel (SAF) for new customer aircraft deliveries in Canada. Avfuel sources SAF from Gevo and blends it with petroleum-based jet fuel. This mixture is then tested for fuel quality and to ensure it meets ASTM D1655 standards.

The product has a net benefit to the environment across its lifecycle. Created from cornstarch, for every one million gallons of the concentrated SAF that is produced, approximately 10 million pounds of animal feed and protein is sold into the food chain, and the final jet fuel product burns cleaner, reducing carbon emissions released into the atmosphere.

In total, Avfuel supplied 7,300 gallons (27,600 liters) of SAF to Bombardier to fuel its new customer aircraft deliveries. In total, the sustainable product provided a two metric ton reduction in life cycle CO2 emissions.

Supply of SAF continues to be the most challenging hurdle to bringing the product to market on a commercial scale. As such, Avfuel hopes raising awareness through initiatives such as this will help inspire commitments by operators to use the product. By creating the demand, Avfuel’s aim is to encourage further production for greater sustainable representation in the fuel supply chain. . . .

HollyFrontier to build $350M renewable diesel unit at Artesia refinery; 125M gallons/year
https://www.greencarcongress.com/2019/1 ... ollyf.html

HollyFrontier Corporation, an independent petroleum refiner and marketer that produces high value light products such as gasoline, diesel fuel, jet fuel and other specialty products, plans to construct a new renewable diesel unit (RDU) at its Artesia, New Mexico refinery (Navajo Refinery).

The RDU will have a production capacity of approximately 125 million gallons a year (9,000 BPD) and allow HollyFrontier to process soybean oil and other renewable feedstocks into renewable diesel. The company expects renewable diesel production to generate >600,000 LCFS credits in year 1.

HollyFrontier said the investment will provide the opportunity to meet the demand for low-carbon fuels while covering the cost of its annual RIN purchase obligation under current market conditions.

The RDU, along with corresponding rail infrastructure and storage tanks, is estimated to have a total capital cost of $350 million, and is expected to be completed in the first quarter of 2022.

The RDU will be funded with cash on hand and is expected to generate an internal rate of return between 20% and 30%. . . .

Trillium opening two California CNG stations fed by renewable natural gas in 2020
https://www.greencarcongress.com/2019/1 ... llium.html

. . . The alternative and renewable fuel provider designed and built CNG stations at two Love’s Travel Stops located in Lost Hills and Tehachapi, California. The stations will offer renewable natural gas (RNG) fueling capabilities to fleet customers.

Produced entirely from organic waste streams, RNG is a low-carbon fuel and interchangeable with pipeline-quality natural gas that reduces greenhouse gas emissions 40-125% (depending on the feedstock) when compared to diesel.

The California Air Resources Board (ARB) recently provisionally certified a Trillium RNG LCFS fuel pathway with a carbon intensity of 49.24 gCO2e/MJ. That particular pathway involves the generation of Landfill Gas at the Meadow Branch Landfill; upgrading the LFG to pipeline-quality biomethane in Athens, Tennesse; and the delivery of the RNG via pipeline to California where it is dispensed as CNG fuel.

The new CNG stations will feature two fast-fill dispensers and will be heavy-duty vehicle accessible. Slated to open in the first quarter of 2020, these two new stations will add to the network of more than 30 private and public Trillium locations located in California.

Gemini Motor Transport, the primary fuel carrier for Love’s Travel Stops, will be fueling its growing CNG fleet of tractor trailers, which use the new Cummins Westport Low NOx 12-liter natural gas engine, with RNG from the two new locations, as well as an existing station in Tulare.

The 24/7 stations will be located at 21948 Highway 46 in Lost Hills and 2000 East Tehachapi Blvd. in Tehachapi, the first Trillium stations in Kern County, a vital transit corridor for California.

Three CA LCFS pathway applications for swine manure to Bio-CNG, Bio-LNG, and Bio-L-CNG; negative triple-digit CIs
https://www.greencarcongress.com/2019/1 ... -lcfs.html


Element Markets Renewable Energy (EMRE) has filed applications for certification of three California LCFS (Low Carbon Fuel Standard) Tier 2 pathways for biomethane (Bio-CNG, Bio-LNG, and Bio-L-CNG) from anaerobic digestion of swine manure produced by Valley View Farms located in Greencastle, Missouri. The calculated carbon intensities are -345.68, -334.41, and -330.87 gCO2e/MJ, respectively.

Smithfield owns and operates the swine farm. Roeslein Alternative Energy, LLC and Smithfield, through Roeslein Alternative Energy of Missouri, LLC, jointly own and operate the biogas collection and processing equipment at the site and own the resulting biomethane.

EMRE purchases and markets the pipeline-injected biomethane and imports it to California for dispensing as CNG or LNG transportation fuel.

Valley View Farms has an average swine population in the range of 40,000 to 50,000. The swine manure is digested in covered lagoons and the biogas control system captures methane that would otherwise be emitted to the atmosphere under baseline manure treatment in anaerobic lagoons.

Biogas is supplied to the gas upgrading facility. Prior to building covered lagoons there were 14 uncovered lagoons (baseline) and all were converted to covered lagoons. However, only six of the covered lagoons are connected to the upgrading facility; all six are included in the analysis. . . .

Pipeline-injected RNG is delivered to CNG stations in the Los Angeles area, or to Applied Natural Gas Fuels, Inc. LNG facility in Topock, Arizona and transported to CNG/LNG stations in California by truck.
