    Dutch researcher Bas Bougie has developed a laser system to investigate soot development in diesel engines. Small soot particles are not retained by a soot filter but are, however, more harmful than larger soot particles. Therefore, soot development needs to be tackled at the source. Laser Induced Incandescence is a technique that reveals exactly where soot is generated and can be used by project partners to develop cleaner diesel engines. Terry Meyer, an Iowa State University assistant professor of mechanical engineering, is using similar laser technology to develop advanced sensors capable of screening the combustion behavior and soot characteristics specifically of biofuels.

    Lithuania's first dedicated biofuel terminal has started operating in Klaipeda port. At the end of November 2007, the stevedoring company Vakaru krova (VK) started activities to manage transshipments. The infrastructure of the biodiesel complex allows for storage of up to 4000 cubic meters of products. During the first year, the terminal plans to transship about 70.000 tonnes of methyl ether, after that the capacities of the terminal would be increased. Investments to the project totaled €2.3 million. Agrimarket - December 5, 2007.

    New Holland supports the use of B100 biodiesel in all equipment with New Holland-manufactured diesel engines, including electronic injection engines with common rail technology. Overall, nearly 80 percent of the tractor and equipment manufacturer's New Holland-branded products with diesel engines are now available to operate on B100 biodiesel. Tractor and equipment maker John Deere meanwhile clarified its position for customers that want to use biodiesel blends up to B20. Grainnet - December 5, 2007.

    In just four months, the use of biodiesel in the transport sector has substantially improved air quality in Metro Manila, data from the Philippines Department of Environment and Natural Resources (DENR) showed. A blend of one percent coco-biodiesel is mandated by the Biofuels Act of 2007 which took effect last May. By 2009, it would be increased to two percent. Philippine Star - December 4, 2007.

    Kazakhstan will next year adopt laws to regulate its fledgling biofuel industry and plans to construct at least two more plants in the next 18 months to produce environmentally friendly fuel from crops, industry officials said. According to Akylbek Kurishbayev, vice-minister for agriculture, he Central Asian country has the potential to produce 300,000 tons a year of biodiesel and export half. Kazakhstan could also produce up to 1 billion liters of bioethanol, he said. "The potential is huge. If we use this potential wisely, we can become one of the world's top five producers of biofuels," Beisen Donenov, executive director of the Kazakhstan Biofuels Association, said on the sidelines of a grains forum.

    German industrial conglomerate MAN AG plans to expand into renewable energies such as biofuels and solar power. Chief Executive Hakan Samuelsson said services unit Ferrostaal would lead the expansion. Reuters - November 24, 2007.

    Analysts think Vancouver-based Ballard Power Systems, which pumped hundreds of millions and decades of research into developing hydrogen fuel cells for cars, is going to sell its automotive division. Experts describe the development as "the death of the hydrogen highway". The problems with H2 fuel cell cars are manifold: hydrogen is a mere energy carrier and its production requires a primary energy input; production is expensive, as would be storage and distribution; finally, scaling fuel cells and storage tanks down to fit in cars remains a huge challenge. Meanwhile, critics have said that the primary energy for hydrogen can better be used for electricity and electric vehicles. On a well-to-wheel basis, the cleanest and most efficient way to produce hydrogen is via biomass, so the news is a set-back for the biohydrogen community. But then again, biomass can be used more efficiently as electricity for battery cars. Canada.com - November 21, 2007.

    South Korea plans to invest 20 billion won (€14.8/$21.8 million) by 2010 on securing technologies to develop synthetic fuels from biomass, coal and natural gas, as well as biobutanol. 29 private companies, research institutes and universities will join this first stage of the "next-generation clean energy development project" led by South Korea's Ministry of Commerce, Industry and Energy.

Eco-Tec biogas purification technology wins contract for greenhouse gas-to-energy project

Ontario based Eco-Tec announces that it has been awarded the contract for a biogas purification system by the Régie de gestion des matières résiduelles de la Mauricie (RGMRM) of Quebec. The integrated process includes the capture, purification and use of biogas as an renewable energy source for greenhouses. Growing products in greenhouses is highly energy intensive, making a switch to the use of locally available biomass waste economical.

RGMRM is a municipal organization that operates most of the municipal landfills in the Mauricie region in Quebec. The landfills, such as the Saint-Étienne-des-Grès landfill and the Trois-Rivières landfill have life spans of over 60 years. Each year one landfill will generate 18,000,000 m3 (635.7 million ft3) of biogas, the energy equivalent of 9,000,000 m3 (318 million ft3) of natural gas. RGMRM has developed and implemented plans to capture the biogas and use it in sustainable development projects that are designed to reduce greenhouse gas (GHG) emissions by approximately 135,000 tons of CO2.

RGMRM's projects have three major advantages: they provide plans to use an environmentally sustainable process to manage the entire life cycle of buried waste; they allow a renewable energy generated from biogas to replace a fossil fuel; and the projects are becoming sources of revenue for RGMRM and the municipalities that use and sell the biogas.

Purification
Biogas is a mixture of methane (CH4) and carbon dioxide (CO2) obtained from the anaerobic fermentation of biomass. However, the renewable gas is often contaminated with toxic quantities of hydrogen sulfide (H2S). To upgrade the biogas into natural gas quality biomethane, purification technologies are applied. Eco-Tec's biogas scrubbing system was selected for RGMRM's projects because of its high efficiency: it removes more than 99% of H2S, results in lower sulfur dioxide (SO2) emissions, reduced equipment corrosion, while offering a solution to other process problems associated with H2S.

The key innovation, from which other advantages arise, is the extremely high mass transfer rate generated by the proprietary gas-liquid contacting system (technical description here). Chemical costs are reduced through the combination of reduced catalyst inventories and concentration, a result of the increased mass transfer rates:

The unit is not affected by fluctuations in biogas feed rates and H2S concentration within the feed, and may be scaled up or down very efficiently. The system also includes self-induced gas flow, which may reduce or eliminate the need for a fan, blower or compressor, and low-pressure drop across the system.

The elemental sulfur by-product is non-hazardous and can be disposed of safely with biosolids, as a fertilizer or in a landfill.

The system was designed to integrate into RGMRM's process, that includes gas conditioning through the removal of water, sulfur and H2S. After purification, the natural gas quality methane is ready for use in power generation, cogeneration and heating applications such as, in this case, heat for tomato greenhouses.

The biogas technology joined Eco-Tec's product lines as an innovation from the researchers from the University of Toronto's Department of Chemical Engineering and Applied Chemistry. Dr. James Smith invented the patented process and joins Eco-Tec in bringing economical and effective Biogas Purification to the global market.

The technology can be used across a wide variety of industries including: pulp and paper mills, landfill gas, industrial processing, wastewater treatment plants, food and beverage processing and meat rendering plants. The biogas purification system reduces greenhouse gases, creates minimal waste and increases energy recovery.

Eco-Tec was recently awarded the Canadian Innovation Award for Environmental Technology, by the Canadian Manufacturers and Exporters association, for this biogas technology.

You are still going to have the CO2, making the quality far from Natural Gas. It's ~ 600 BTU/cu.ft vs. 1000 BTU/cu.ft.
