Bio-Energy Retains Its Mitigation Potential Under Elevated CO2

[tweetmeme http://www.URL.com]   Marion Liberloo (University of Antwerp), and co-authors mentioned below in the citation, have issued a paper titled „Bio-Energy Retains Its Mitigation Potential Under Elevated CO2.“  The abstract to this good analytical paper reads:

If biofuels are to be a viable substitute for fossil fuels, it is essential that they retain their potential to mitigate climate change under future atmospheric conditions. Elevated atmospheric CO2 concentration [CO2] stimulates plant biomass production; however, the beneficial effects of increased production may be offset by higher energy costs in crop management.

Methodology/Main Findings

We maintained full size poplar short rotation coppice (SRC) systems under both current ambient and future elevated [CO2] (550 ppm) and estimated their net energy and greenhouse gas balance. We show that a poplar SRC system is energy efficient and produces more energy than required for coppice management. Even more, elevated [CO2] will increase the net energy production and greenhouse gas balance of a SRC system with 18%. Managing the trees in shorter rotation cycles (i.e., 2 year cycles instead of 3 year cycles) will further enhance the benefits from elevated [CO2] on both the net energy and greenhouse gas balance.

Conclusions/Significance

Adapting coppice management to the future atmospheric [CO2] is necessary to fully benefit from the climate mitigation potential of bio-energy systems. Further, a future increase in potential biomass production due to elevated [CO2] outweighs the increased production costs resulting in a northward extension of the area where SRC is greenhouse gas neutral. Currently, the main part of the European terrestrial carbon sink is found in forest biomass and attributed to harvesting less than the annual growth in wood. Because SRC is intensively managed, with a higher turnover in wood production than conventional forest, northward expansion of SRC is likely to erode the European terrestrial carbon sink.

  1. Origin oil a great green investment

    Aussie government grants 5 million to turn carbon into algae oil. Origin Oil and MBD Energy’s carbon capturing dreams poised for growth!

    Mbd energy is origin oils first customer. The two are collaborating to capture carbon from existing power plants and produce oil. If successful profitability is inevitable.  The oil produced will be able to take part in fueling our nations energy needs.

    Below is a link to the news and a quote from the article explaining their terms of agreement.

     ”In the initial phase, OriginOil will equip MBD Energy’s research and development facility at James Cook University in Queensland, Australia, where testing will take place. The two companies agreed that, subject to the success of the initial test phase, MBD will purchase significantly larger feeding and OriginOil extraction units to serve facilities planned for its three Algal Synthesizer power station projects in Australia: Tarong Energy (Queensland), Loy Yang A (Victoria) and Eraring energy(New South Wales).”

    (If trials work, mbd will be fully financially committed to the  purchasing and production of this technology.)

     

    This article published July 9th 2010 by James Cook university allows potential investors and those following origin oil and mbd energy to conclude that the tests were a success and that mbd energy is going to be purchasing larger more expensive units from Origin Oil. The link  below followed by an important quote will explain my claims.

    “Senator Carr visited the MBD-JCU research facility at the Townsville campus and inspected the facility – a pilot project that is aimed at commercializing the development of Bio Carbon and Capture Storage technology. The process consumes large quantities of greenhouse gases while producing low cost bio-oil and animal feedstock” 

    (the research facility at the Townsville campus was an integration of Mbd and Originoil’s technology.)

    Summary-First, Origin Oil and MBD energy integrated and tested each others technology at James Cook university.  The trials were successful.  They called in the Aussie government to evaluate. The Aussie government evaluated the facility and rewarded their successes with government funding.

    Origin oil trades under the symbol (ooil) and is a great buy and hold play.  Should not be day traded, should be a strict buy and hold trade to benefit off of later in life.      

    I feel this new innovative project will create thousands of jobs and create a paradigm shift in capturing carbon.

    Feedback? Thanks 🙂
