FEMA Gasifier Section

For reasons I am do not entirely understand, I am blessed with an obscene amount of energy tonight (despite leading a tour for 22 at our home yesterday and installing a 140 sq ft rain garden today), so I am whipping up a 5000 word section on Wood Chip Gasifiers. We brought our gasifier to the MREA last weekend and it was a HUGE hit, so I wanted to get more of my info online in readable form -including the complete plans.

Please check out the Gasifier Parent Page, and all its little offspring in the left column should you want to know more about this incredible way to create energy -its even carbon negative!

  1. Thanks for the info Rob. Get some rest.

  2. Will do Kelly -just after I stack the truckload of 80 wine barrels we unloaded this morning. Its ok -they only weigh 100 lbs each!

    Sleeping tonight will not be difficult!

  3. that is awesome, you’ve piqued my curiosity, and I think I can convince a friend to be a co-conspirator in a gasifer project. How is this carbon negative? I’m not sure I understand that part.

  4. Great Kory! It is carbon negative because 100% of the carbon input into the system is “recently” pulled from the air by the trees (7-30 years ago) and 50% of that carbon is then sequestered into the pelletized charcoal that is the primary waste product.

    Charcoal in this state is very stable -lasting for thousands of years in the soil. Remember reading about archaeological studies of old Indian sites? They always mention the “burn pits” which they find because all the charcoal is still there after 3000 years. If that charcoal is used as a soil amendment instead of as a secondary fuel, that carbon is sequestered -so for every ton of carbon burned in a gasifier, 1000lbs of carbon is removed from the atmosphere for a very long time -making it carbon negative in regards to Atmospheric Carbon.

    The “Why Gasifiers Rock” page gets into it in a bit more detail.
