^ 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. . . .
