A report prepared by ISIS (Institute of Studies for the Integration of Systems - Italy) together with Tecnalia (Spain) for the European Parliamentary Research Service (EPRS) discusses the technological, environmental and economic barriers for producing methanol from carbon dioxide, as well as the possible uses of methanol in car transport in Europe.

The study evaluated costs and benefits from a life cycle perspective in order to compare various raw materials for producing methanol and in order to reflect the potential benefits of methanol obtained from CO2. The report concluded that benefits in the medium- and long-term can be anticipated since the obtaining of an alternative fuel using a residual greenhouse gas would allow European dependence on conventional fossil fuels to be cut, and that way the risks in supply security to be minimized.

New nickel-gallium catalyst could lead to low-cost, clean production of methanol; small-scale, low-pressure devices

March 03, 2014

Scientists from Stanford University, SLAC National Accelerator Laboratory and the Technical University of Denmark have identified a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol at ambient pressure and with fewer side-products than the conventional catalyst. The results are published in the journal Nature Chemistry.

The researchers identified the catalyst through a descriptor-based analysis of the process and the use of computational methods to identify Ni-Ga intermetallic compounds as stable candidates with good activity. After synthesizing and testing a series of catalysts, they found that Ni5Ga3 is particularly active and selective. Comparison with conventional Cu/ZnO/Al2O3 catalysts revealed the same or better methanol synthesis activity, as well as considerably lower production of CO.

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.

Converting glycerol from biodiesel production into bio-gasoline

December 16, 2013

A team at the University of Idaho has demonstrated that glycerol, a byproduct from biodiesel production, could be used as a substrate for producing drop-in gasoline-range biofuel. In a paper published in the ACS journal Energy & Fuels, Guanqun Luo and Armando G. McDonald describe their study of converting methanol (MTG) and a mixture of methanol and glycerol (MGTG) into gasoline-range hydrocarbons using a bench-top, fixed-bed microreactor.

The MTG- and MGTG-generated liquids showed a similar composition, mainly methylbenzenes, to regular gasoline, and composition changed as the reaction proceeded to favor heavier aromatics.

On 1 July MAN Diesel & Turbo announced the development of a new ME-LGI dual fuel engine. The new engine expands the company’s dual-fuel portfolio, enabling the use of more sustainable fuels such as methanol and Liquefied Petroleum Gas (LPG).

MAN has now signed a Letter of Intent with Vancouver-based Waterfront Shipping for the use of four MAN ME-LGI engines on its ships. The engines will run on a blend of 95% methanol and 5% diesel fuel.

VTT study concludes gasification-based pathways can deliver low-carbon fuels from biomass for about 1.90-2.65 US$/gallon

July 04, 2013

A study by researchers at Finland’s VTT has concluded that it is possible to produce sustainable low-carbon fuels from lignocellulosic biomass for as estimated gasoline-equivalent production cost of 0.5–0.7 €/liter (app. 1.90-2.65 US$/gallon US), with first-law process efficiency in the range of 49.6–66.7%—depending on the end-product and process conditions. Should the thermal energy produced as a by-product be exploited for district heat or industrial steam, the overall efficiency from biomass to salable energy products could reach 74–80%.

In their study, Ilkka Hannula & Esa Kurkela evaluated 20 individual biomass-to-liquids BTL plant designs based on their technical and economic performance. The investigation was focused on gasification-based processes that enable the conversion of biomass to methanol, dimethyl ether, Fischer-Tropsch liquids or synthetic gasoline at a large (300 MWth of biomass) scale.
