The regrown forest is only, and can only be, a pale copy of what was before, and likely will never be as robust, unless forest soils are annually fertilized, as with most planted forest areas in the US southeast. Petro dollar - euro hydrogen?“What was still a dream a year ago is now becoming a real possibility. – PV . Your access to Member Features is limited. The difference of opinion regarding CO2 emissions from wood burning is not among scientists, but between scientists and wood burning proponents. There is a common perception that burning trees to generate heat or electricity should be considered “zero emissions” or “carbon neutral” because the carbon dioxide (CO 2) released during burning is either recaptured by photosynthesis as trees regrow, or the CO 2 already sequestered by trees cancels out the emissions. However, Vermont’s 2014 harvest was 1,330,674 dry ton, an excess removal of 350,265 dry ton, per USFS. So although such forests act as carbon stores, they release as much carbon dioxide as they absorb. It is not clear why Vermont has such a high value. Good post. California ISO Report on system and market conditions, issues and performance: August and September 2020, Achieving New England State Energy Goals within an AOCE NEPOOL Wholesale Capacity Market Design, "I place this observation in the category of Practice trumping theory. Willem, '", Control Room Operator/Performance Engineer, Reliability Compliance Specialist/Sr. Dry, seasoned wood generally produces the least harmful smoke and the most heat. that temperatures in cities are higher than in rural areas, it is substantial. Carbon dioxide is the most common gas produced by burning wood. If Frank Shu’s paper on molten-salt “supertorrefaction” (actually, fast carbonization) is correct about the tar-free composition of the syngas product, we’re 90% of the way there. “Burning wood is CO2-neutral” is used by wood burning proponents to bamboozle Vermonters. Those sinks are working at full capacity. Burning one ton of green wood creates 2000 x (1- 0.45) x 0.5 x (44/12)/2000 = 1.00833 ton of CO2 emissions. But what does the right kind of biomass look like? BERC estimates, based on its criteria, about 46.8% of Vermont’s forests inventory of live trees is low-grade, i.e., suitable for wood burning. _____ There’s enough excess H2 in the tail gas that considerably more could be made if desired. This water is heated by the fire until it evaporates along with tars and resins, floating away as water vapor. And burning both oil and coal are 100% carbon-neutral if we extend it ten million years or so further into the past. NOTE: Below are listed the wood tonnage and combustion CO2 tonnage of Vermont’s wood chip power plants in 2015. http://www.maforests.org/McNeil Emissions 2015.pdf, http://www.maforests.org/RYEGATE TECHNICAL.pdf, http://fpr.vermont.gov/sites/fpr/files/About_the_Department/Library/Library/FINAL_2015 Residential Fuel Assessment Report.pdf, http://www.maforests.org/VermontBiomassBiomess.pdf, Photo Credit: InspireFate Photography via Flickr. The more smoke that wood produces as it burns, the less heat it creates, so a small amount of smoke is desirable when burning wood. I move we ditch truth entirely, and relabel the current insanity humankind’s “post-thought” era. (I have such a collection of refutations of Bas’ habitual lies that, given the ability to run scripts as a comment-filter here, links to the rebuttals could be automagically inserted as part of the posting process and save everyone the trouble.). Incomplete combustion doesn’t only happen when natural gas is burned. Biomass beats solar PV, but both are significantly worse than nuclear, hydro, and wind. Green hydrogen can become a new commodity,” said Valerie Bouillon-Delporte, President of Hydrogen Europe.Join me and over 1100 companies and.. President-elect Joe Biden is taking a much firmer stance on the climate crisis than his predecessors, even Clinton and Obama. NOx is an acidic compound that combines with water easily in the atmosphere, forming the infamous acid rain. A pity that you promote outdated figures from a strong pro-nuclear institute. Wind & solar becames 3-10 times cheaper due to efficiency improvements, which implies also 3-10times less emissions. The graphic perpetuates the politically correct myth, “wood burning is CO2-neutral”. Burning Wood Yields High CO2/Energy Unit Compared to Other Fuels: Forests, other biomass and oceans, acting as sinks, absorb atmospheric CO2 from any source. As part of renewable energy programs, these forests are seen as useful for producing thermal and electrical energy. Moreover, burning wood releases all the carbon dioxide in one roaring blaze, whereas your decaying pile would take years to break down, meaning that brush would do way less damage while we wait for the human race to come to its sense, call off … Ultra super-critical coal plants (efficiency for the new types 46%) also can and sometimes do burn mixtures of coal and biomass. If it’s not burned by humans, nature will do it in part via putrefaction & fire. That environmental destruction was followed by about 4 decades of acid rain, 50s – 80s, which had the same effect as clear-cutting regarding nutrients leaching out, such as calcium, a vital nutrient for biomass growth. It is not clear why Vermont has such a high value. al. Burning of lignite emits nearly 100 % more carbon dioxide with respect to the energy content than burning of natural gas. “Those sugars move down the trunk of the tree. So you should correct the NREL results for the cost =~ emission changes since the av. Of the 2,100 reference they evaluated, 85% did not meet their standards for quality and had to be discarded. Please show them your appreciation by leaving a comment, 'liking' this post, or following this Member. Only nuclear electric, excess wind electric, and concentrated solar seem useful energy to add for resultant fuel. It is mostly traded informally and non-commercially. When we talk about investments, we should consider next decades. When these materials burn there is a complex chemical reaction in which numerous byproducts are produced, including carbon dioxide. If you were to burn hydrogen for example, then it would react and form water (H + O2 = H2O). Vermont Excessive Harvesting: According to USFS standards regarding nutrition, habitat, etc., Vermont harvest removals should be limited to 980,410 dry ton/y. – Wind are >2 times less now; http://www.theenergycollective.com/willem-post/2394110/is-burning-wood-co2-neutral, http://www.theenergycollective.com/willem-post/2392251/wood-for-fuel-logging-increases-co2-and-damages-forest-health, http://www.theenergycollective.com/willem-post/2390703/a-comparison-of-wood-chip-and-oil-fired-power-plants, http://www.theenergycollective.com/willem-post/2225851/economics-and-co2-emissions-montpelier-district-heating-plant. source. When you apply those corrections you see that my original statement: I think that the new plant we have here, which claims 46% efficiency, also has SOX scrubbing systems and fabric filter particulate removal systems. *Plus about 15%, if wood chips, plus about 30%, if wood pellets. Carbon monoxide can also form when wood, oil or charcoal are burned. While the NREL report is dated Jan.2013, it summarizes results of studies published in the 1989-2010 period. I couldn’t find corrections for the cost changes (hence the associated CO2eq emissions changes), since the original studies are published. FERC Order 890 calls for an open, transparent stakeholder planning process. Here’s another LCA, which includes fossil gas and biomass. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful. There are turnkey methanol plants which convert any stream of CO+CO2+H2 into MeOH plus tail gas (and water in the case of CO2). The Naturalists of the 18th century wrote famously about it. http://fpr.vermont.gov/sites/fpr/files/Forest_and_Forestry/Forest_Based_Business/Library/2015 FIA Annual Report.pdf, http://fpr.vermont.gov/sites/fpr/files/Forest_and_Forestry/Forest_Based_Business/Library/2012 Forests_of_VT_and_NH.pdf.
