DOE soliciting projects in advanced coal gasification for high carbon-capture power production and/or liquid fuels

February 26, 2014

The US DOE is soliciting (DE-FOA-0001051) projects for up to $10 million in awards to target technological advancements to lower the cost of producing hydrogen and/or high-hydrogen syngas from coal for use in 90% carbon capture power generation and/or gasification-based liquid (transportation) fuel production: methanol or diesel. Liquid fuel production must be GHG equivalent to conventional petroleum-based processes.

The work is also designed to assure significant reduction in the cost of coal conversion and environmental impacts, enabling coal resources to both improve US economic competitiveness and provide environmental benefits over the globe, according to the DOE.

Primus Green Energy’s STG+ patent for liquid fuel synthesis from syngas approved

February 05, 2014

Primus Green Energy Inc., an alternative fuel company that converts natural gas and other feedstocks directly into drop-in transportation fuels and solvents (earlier post), announced that its patent application covering its STG+ liquid fuel synthesis technology has been allowed by the US Patent and Trademark Office (USPTO). STG+ produces high-quality, cost-effective, drop-in liquid transportation fuels directly from syngas derived from natural gas and other carbon-rich feedstocks in a single-loop process.

STG+ essentially improves upon commercial methanol synthesis processes and ExxonMobil’s methanol-to-gasoline (MTG) process, combining them into an integrated, optimized system that efficiently converts syngas directly to fuels. In addition to the gasoline product, the STG+ process can also produce jet fuel, diesel and high-value chemicals by changing the catalysts and operating conditions. The company, which is currently producing synthetic gasoline at its demonstration plant (earlier post), plans to build several more reactors in parallel to the current production train for other fuel products.

The synthesis stage of Karlsruhe Institute of Technology’s (KIT’s) multi-stage bioliq pilot plant has begun operation and has produced biogasoline. All stages of the bioliq process—flash pyrolysis, high-pressure entrained-flow gasification, and now synthesis—have now been realized and the project will now be completed by testing the entire process chain and optimizing it for the large industrial scale.

As soon as all stages of the bioliq process will have been linked, the pilot plant will supply high-quality fuel from straw, probably in mid-2014. The complete bioliq process (Biomass to Liquid Karlsruhe) comprises four stages (earlier post):

Fulcrum BioEnergy demonstrates integrated process to convert MSW to jet and diesel; $4.7M DoD grant to begin plant engineering

May 28, 2013

Fulcrum BioEnergy, Inc. has successfully demonstrated the conversion of municipal solid waste (MSW)—household garbage—into jet and diesel fuels. Fulcrum says its ability to produce drop-in fuels from MSW opens up an 80 billion gallon per year fuel market and expands its customer base for its national development program.

This demonstrated process adds fuel diversity to Fulcrum’s products and complements its previously demonstrated MSW-to-ethanol process. For that process, Fulcrum uses a two-stage thermochemical process involving gasification of municipal solid waste (MSW) followed by the catalytic conversion of the syngas to ethanol. (Earlier post.)

Advanced biofuels technologies have developed significantly over the past several years, according to a status report on demonstration facilities prepared for IEA Bioenergy Task 39—a group of international experts working on commercializing sustainable biofuels used for transportation that is part of the International Energy Agency’s (IEA) implementation agreement for bioenergy, IEA Bioenergy.

Hydrotreatment—as exemplified by Neste Oil’s NExBTL—has been commercialized and currently accounts for approximately 2.4% of biofuels production worldwide (2,190,000 t/y), according to the report. Fermentation of lignocellulosic raw material to ethanol has also seen a strong development and several large scale facilities are just coming online in Europe and North America. The production capacity for biofuels from lignocellulosic feedstock has tripled since 2010 and currently accounts for some 140,000 tons per year.
