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.

Sasol, GE develop new anaerobic microbial technology for cleaning of Fischer-Tropsch waste water; boosting gas-to-liquids (GTL) value proposition

November 06, 2013

Sasol and General Electric (GE: NYSE)’s GE Power & Water have together developed new technology that will clean waste water from Fischer-Tropsch plants used to produce synthetic fuels and chemicals, while also providing biogas as a by-product for power generation. The new Anaerobic Membrane Bioreactor Technology (AnMBR) will be further developed at a new demonstration plant at Sasol’s R&D Campus at its Sasol One Site in Sasolburg, South Africa.

AnMBR involves anaerobic micro-organisms that are able to live in environments devoid of oxygen, such as sediment layers on floors of lakes, dams and the ocean. Sasol currently uses aerobic microbes to treat GTL and coal-to-liquids (CTL) effluents in ORYX GTL, Qatar and Synfuels, Secunda facilities.

DOE and Air Force issue RFI on Mil-Spec jet fuel production using coal-to-liquid technologies

September 05, 2013

The US Department of Energy (DOE) in partnership with the US Air Force has issued a request for information (RFI)—DE-FOA-0000981—on research & development aimed at greenhouse gas emissions reductions and cost competitiveness of Mil-Spec jet fuel production using coal-to-liquid (CTL) fuel technologies.

The DOE’s National Energy Technology Laboratory (NETL), on behalf of the US Air Force, intends to issue a funding opportunity announcement (FOA) in 2013 that would solicit for the most promising research and development projects on advanced concepts for and/or unit operations within a CTL fuels plant; the areas of interest may be developed based in part on the responses to the RFI. The DOE and US Air Force anticipate the need for projects of no less than $3 million and that would have duration of not more than 3 years.

EIA: world energy consumption to grow 56% 2010-2040, CO2 up 46%; use of liquid fuels in transportation up 38%

The US Energy Information Administration’s (EIA’s) International Energy Outlook 2013 (IEO2013) projects that world energy consumption will grow by 56% between 2010 and 2040, from 524 quadrillion British thermal units (Btu) to 820 quadrillion Btu. Most of this growth will come from non-OECD (non-Organization for Economic Cooperation and Development) countries, where demand is driven by strong population and economic growth; energy intensity improvements moderate this trend

Renewable energy and nuclear power are the world’s fastest-growing energy sources, each increasing 2.5% per year, according to the biennial report. However, fossil fuels continue to supply nearly 80% of world energy use through 2040. Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase. Given current policies and regulations limiting fossil fuel use, worldwide energy-related CO2 emissions rise from about 31 billion metric tons in 2010 to 36 billion metric tons in 2020 and then to 45 billion metric tons in 2040, a 46% increase over the 30-year span.

China-US team develops new platinum-cobalt nanocatalysts for low-temperature aqueous phase Fischer-Tropsch synthesis

March 07, 2013

Researchers from China and the US have developed Pt−Co nanoparticles (NPs) which proved to be effective and efficient catalysts for aqueous-phase Fischer-Tropsch synthesis (FTS) at 433 K (160 °C)—a lower operational temperature than can be achieved with conventional catalysts. A report on their work is published in the Journal of the American Chemical Society.

Fischer−Tropsch synthesis is a well-established catalytic process that converts syngas derived from fossil fuels or biomass to liquid fuel products. As the process is highly exothermic and thermodynamically favored at low temperature, it is desirable to develop a catalyst system that could facilitate working at low reaction temperature while maintaining excellent catalytic performance, they note.

Researchers develop new Fischer-Tropsch catalyst and production method; Total patents both

March 05, 2013

A team of researchers led by University of Amsterdam (UvA) chemists has developed new Fischer-Tropsch catalysts—consisting of ultra-thin cobalt shells surrounding inexpensive iron oxide cores—that can be used to produce synthetic fuels from natural gas and biomass. The method used to produce the catalysts is based on an approach previously optimized for preparing magnetic tape for audio cassettes in the 1960s.

France-based energy major Total, which was part of the research team, has patented the new catalysts and the method for their preparation, naming the UvA researchers as co-inventors. The research has just been published online as a VIP (very important paper) communication in the journal Angewandte Chemie.
