    Tonight at 9pm, BBC Two will be showing a program on geo-engineering techniques to 'save' the planet from global warming. Five of the world's top scientists propose five radical scientific inventions which could stop climate change dead in its tracks. The ideas include: a giant sunshade in space to filter out the sun's rays and help cool us down; forests of artificial trees that would breath in carbon dioxide and stop the green house effect and a fleet futuristic yachts that will shoot salt water into the clouds thickening them and cooling the planet.

    Archer Daniels Midland, the largest U.S. ethanol producer, is planning to open a biodiesel plant in Indonesia with Wilmar International Ltd. this year and a wholly owned biodiesel plant in Brazil before July, the Wall Street Journal reported on Thursday. The Brazil plant is expected to be the nation's largest, the paper said. Worldwide, the company projects a fourfold rise in biodiesel production over the next five years. ADM was not immediately available to comment. Reuters - Feb. 16, 2007.

    Finnish engineering firm Pöyry Oyj has been awarded contracts by San Carlos Bioenergy Inc. to provide services for the first bioethanol plant in the Philippines. The aggregate contract value is EUR 10 million. The plant is to be build in the Province of San Carlos on the north-eastern tip of Negros Island. The plant is expected to deliver 120,000 liters/day of bioethanol and 4 MW of excess power to the grid. Kauppalehti Online - Feb. 15, 2007.

    The government of Taiwan has announced its renewable energy target: 12% of all energy should come from renewables by 2020. The plan is expected to revitalise Taiwan's agricultural sector and to boost its nascent biomass industry. China Post - Feb. 2, 2007.

    Production at Cantarell, the world's second biggest oil field, declined by 500,000 barrels or 25% last year. This virtual collapse is unfolding much faster than projections from Mexico's state-run oil giant Petroleos Mexicanos. Wall Street Journal - Jan. 30, 2007.

    Dubai-based and AIM listed Teejori Ltd. has entered into an agreement to invest €6 million to acquire a 16.7% interest in Bekon, which developed two proprietary technologies enabling dry-fermentation of biomass. Both technologies allow it to design, establish and operate biogas plants in a highly efficient way. Dry-Fermentation offers significant advantages to the existing widely used wet fermentation process of converting biomass to biogas. Ame Info - Jan. 22, 2007.

    Hindustan Petroleum Corporation Limited is to build a biofuel production plant in the tribal belt of Banswara, Rajasthan, India. The petroleum company has acquired 20,000 hectares of low value land in the district, which it plans to commit to growing jatropha and other biofuel crops. The company's chairman said HPCL was also looking for similar wasteland in the state of Chhattisgarh. Zee News - Jan. 15, 2007.

    The Zimbabwean national police begins planting jatropha for a pilot project that must result in a daily production of 1000 liters of biodiesel. The Herald (Harare), Via AllAfrica - Jan. 12, 2007.

    In order to meet its Kyoto obligations and to cut dependence on oil, Japan has started importing biofuels from Brazil and elsewhere. And even though the country has limited local bioenergy potential, its Agriculture Ministry will begin a search for natural resources, including farm products and their residues, that can be used to make biofuels in Japan. To this end, studies will be conducted at 900 locations nationwide over a three-year period. The Japan Times - Jan. 12, 2007.

    Chrysler's chief economist Van Jolissaint has launched an arrogant attack on "quasi-hysterical Europeans" and their attitudes to global warming, calling the Stern Review 'dubious'. The remarks illustrate the yawning gap between opinions on climate change among Europeans and Americans, but they also strengthen the view that announcements by US car makers and legislators about the development of green vehicles are nothing more than window dressing. Today, the EU announced its comprehensive energy policy for the 21st century, with climate change at the center of it. BBC News - Jan. 10, 2007.

    The new Canadian government is investing $840,000 into BioMatera Inc. a biotech company that develops industrial biopolymers (such as PHA) that have wide-scale applications in the plastics, farmaceutical and cosmetics industries. Plant-based biopolymers such as PHA are biodegradable and renewable. Government of Canada - Jan. 9, 2007.

Energy crops may soak up methane water

Quicknote bioenergy technology
Earlier we reported about several studies, tests and projects dealing with the bioremediation of brownfields and mining sites using biofuel crops. Such energy crops can be planted on polluted sites to prevent erosion, remove pollutants from the soil, stop the spread of small toxic particles through the air and to clean up ground water. After having done their work, the crops can be harvested and used as a feedstock for biofuels.
Now a company in northern Wyoming is conducting tests to see if growing hybrid poplar trees might be a good way to use water produced from coal-bed methane wells. The study of the process known as "phytoremediation" is being conducted by water resource management group CBM Associates and methane producer Windsor Energy Group.

The extraction of coal-bed methane or coalbed gas consists of drilling a steel-encased hole into a coal seam (200 - 1500 meters below ground). As the pressure within the coal seam declines, due to the hole to the surface or the pumping of small amounts of water from the coalbed, both gas and 'produced water' escape to the surface through tubes. Then the gas is sent to a compressor station and into natural gas pipelines. The 'produced water' is most often released into streams or pumped back into the ground. This 'methane water' typically contains sodium bicarbonate and chloride and if left untreated, it pollutes ground water.

Phytoremediation is the removal of pollutants by the use of engineered tree systems. The hybrid poplars were selected because they absorb large amounts of water relative to their growth. One acre of trees will use 1 million to 1.5 million gallons of water per year, according to environmental engineer and project manager Chris Ewert.

Ewert said he has seen hybrid poplars planted on top of covered landfills because they soak up a lot of water and don't let it become groundwater that could become polluted. "The trees use so much water, so I figured why not?" Ewert said in proposing the study. In April about 3,000 poplars were planted in a three-acre site. Methane well water is irrigating the trees through a gravity-fed sprinkler system from a reservoir. Ewert said the trees will be monitored the rest of the summer. Some have already grown 2 feet since they were planted.

"Some can grow six to eight feet in one year," Windsor environmental specialist Patsy Ballek said. The study will continue for 10 years, Ballek said. If the study is successful, Ewert said, the trees could be planted in tree belts near coal-bed methane well water reservoirs to give producers another means of using the water. Water is pumped to the surface by wells in order to recover the methane. "The water will be used by the trees and not go in the ground," Ewert said. As the study continues, Ewert said planting the trees on a larger scale will be analyzed for cost-effectiveness. "It definitely could prove to be viable," Ewert said.

Hybrid poplars are known to be fast growing trees and are proposed as energy crops in fast rotation cropping systems. They yield up to 35 metric tonnes of dry matter per year, and are considered to be excellent carbon sinks.
