COLUMN-Biomass Burners Beware New EU Oversight: Wynn
By Gerard Wynn Aug 21 (Reuters) – Utilities planning to invest in wood-fired power plants beware: the European Commission’s draft green standards for burning biomass would regulate carbon emissions from burning wood for the first time. At present, EU laws favouring green energy have led countries to pay generous subsidies for burning biomass, but in the future developers would have to meet the new standards to get those incentives. (For draft copy, see Chart 1) Greater scrutiny is appropriate, given the present assumption that burning wood produces no carbon emissions at all, under renewable energy and carbon trading laws. Biomass including wood, energy crops, food crops and waste is the main source for renewable energy in Europe, and accounts for 7 percent of all EU energy consumption. Until now, only biomass used to make liquid biofuels for road transport has been subjected to “sustainability criteria” – a check list to make sure they are environmentally friendly. The Commission will now propose to widen similar, binding criteria to biomass used to generate heat and power, which accounts for more than four times the energy of biofuels. It is only a first step, and will probably take several years to legislate. But the direction is important: the Commission’s track record is to toughen environmental regulation over time, and the case of biofuels is illustrative. As a directive, the proposals need backing from the European Parliament and member states, where the haggling will start. Academic literature suggests that there is room for argument that many existing sources of biomass would fail to meet the new criteria, with implications for biomass demand, project returns and rival low-carbon electricity technologies. *************************************** Chart 1: link.reuters.com/jep52v Chart 2: (page 238) link.reuters.com/nep52v Chart 3: (page 6) link.reuters.com/pep52v *************************************** DRIVE EU countries face a collective target to get a fifth of all energy, including power, heat and transport, from renewable sources by 2020. Member states have published details of how they will meet their 2020 goals, which the European Environment Agency (EEA) aggregated into EU-wide data. Burning biomass to produce heat and electricity would together account for 44 percent of all EU renewable energy consumption in 2020, according to the EEA report, “Renewable Energy Projections as Published in the National Renewable Energy Action Plans of the European Member States”. (Chart 2) That is far ahead of higher profile sources, such as wind power (18 percent of all renewable energy in 2020); biofuels (13 percent); and solar power (4 percent). The new regulations will therefore no doubt be bedded in softly, initially, not to upset the bloc’s entire green energy strategy. Britain, for example, has been especially active lately in supporting biomass power – faced with concern about a blackout risk due to coal plant closures. It has recently granted planning approval for 6,940 megawatts of dedicated biomass power plants, refusing just 209 MW, with a further 456 MW in the application pipeline, planning data show. Electric utilities involved in various stages of planning approval include E.ON, GDF Suez, RWE , Scottish Power. EU DRAFT The EU’s 2009 renewable energy law required the Commission to investigate possible oversight of biomass, beyond biofuels. The Commission said in 2010 that it did not then see the need for binding rules, making recommendations instead. The Commission has now had a change of heart, arguing that it is better to have a single set of binding obligations for all biomass across all 28 member states, to avoid confusion. The new rules for biomass heat and power broadly follow the existing guidelines for biofuels. They would require a minimum greenhouse gas saving of 60 percent compared with fossil fuels (including the carbon emissions from burning the fuel to generate electricity or heat); particular emissions values for biomass feedstocks and processes; and protection of forests with high conservation value. It may safeguard existing investments by applying the new criteria only to new installations, but the draft does not spell that out. DEBATE The new proposals do not list greenhouse gas savings for various types of biomass compared with fossil fuels – perhaps because that will be the most contested item. But in its note three years ago, the Commission cited its own in-house research (the Joint Research Centre) calculating savings for 20 different sources of biomass for heat and power. Regarding electricity generation from biomass, the research showed that 11 sources would fail the proposed 60 percent threshold; for heat generation, five would fail. (Chart 3) The JRC numbers show two critical factors determining greenhouse gas savings: first, the fuel used for processing the biomass, whether natural gas or less carbon-emitting wood and other forest residues. And second, the source of the biomass, whether from the EU or from tropical sources, where the latter may be primary rather than managed forest, and with higher transport emissions. No doubt, environmental and industry lobbies will haggle over the numbers. More important is the direction. The European Commission has in the past shown a bias towards making environmental legislation tougher, once it is introduced. The biofuel rules are illustrative. The EU approved biofuel consumption targets and sustainability criteria in the 2009 renewable energy law. Next month, the European parliament will vote on halving the previously agreed target for food-based biofuels, shifting support towards fuels with much lower emissions. “The Commission is of the view that in the period after 2020 biofuels which do not lead to substantial greenhouse gas savings and are produced from crops used for food and feed should not be subsidised,” the Commission says, in a policy shift on biofuels which the biomass industry should now be wary of.

European Climate Policy Drives Wood Pellet Boom In NC
Published: August 17, 2013 The pellet economy Enviva estimates the economic impact of its pellet mills in Ahoskie and Garysburg and its planned export terminal at the Wilmington port: • Ahoskie: 74 workers, average salary $35,000. Enviva buys timber worth $21 million from North Carolina and Virginia loggers. Produces 365,000 tons of pellets for $170 a ton. • Garysburg (Northampton County): 79 workers, average salary $35,000. Enviva buys timber worth $35.4 million from North Carolina and Virginia loggers. Produces 500,000 tons of pellets for $170 a ton. • Wilmington: $40 million to build export terminal, to begin operation in 2015 with 23 workers, average salary $37,783. One million tons of pellets to be exported on 25 to 30 vessels per year. Not included here: Two mills that will produce pellets for export through Wilmington. Source: Enviva LP By Bruce Siceloff — bsiceloff@newsobserver.com AHOSKIE — In the searing August heat, big yellow logging machines pile up the harvest from 153 acres of sweet gum, red oak and maple trees. A roaring log loader grabs the trunks to slice off 16-foot logs and stack them for one of the sawmills that provide a traditional market for Eastern North Carolina timber. These logs are worth $20 to $40 a ton and will be turned into plywood, cabinets and veneer. In a second woodpile, there’s new money. Limbs and leafy treetops are stacked alongside trees as big as 16 inches across. They cannot be sold as saw logs because they’re forked or knotty, crooked or hollow. This pile will be fed into a chipper and milled at an Ahoskie factory that makes 1,000 tons, every day, of a minor American fuel product suddenly in hot demand on the other side of the Atlantic: wood pellets. Two years ago, everything in this second pile would have been left on the ground to rot, said David Jennette, a Windsor forester who is managing this timber harvest. Now it brings $2 to $8 a ton. “When you’re talking about 50 to 75 tons of chips to the acre, and maybe more, that’s a significant amount of money going back to the landowner that we weren’t able to get before,” Jennette said. The wood pellet industry is enjoying a speedy, zero-to-60 growth surge across the southeastern United States. Hundreds of millions of dollars are being invested in factories – some of them converted from old lumber mills – in coastal plain forests from Virginia to Louisiana. They are serving a market created, almost overnight, by paradoxical environmental policies that are driving European electric utilities to burn imported wood in their boilers instead of coal. Maryland-based Enviva LP , the nation’s biggest pellet maker, opened its Ahoskie mill in 2011 and a second one in Northampton County this year. Together, they produce 865,000 tons of pellets annually to be shipped out of the port at Chesapeake, Va. In 2015, Enviva expects to start exporting an additional million tons from a planned $40 million terminal at the Wilmington port. The company is scouting sites for two new pellet mills in southeastern North Carolina, one of them in Sampson County. At the same time, California-based International WoodFuels has said it will produce 285,000 tons a year from a planned pellet mill in Wilson County and a new export terminal at the Morehead City port. The pellet industry is founded on a climate-friendly, carbon-neutral rationale. Our forests use photosynthesis to soak up carbon dioxide, enough to compensate for 14 percent of all emissions in the United States. This stored-up carbon is released into the air when wood pellets are burned, but wood is called a renewable fuel because that carbon eventually is recaptured by new trees that grow in place of the old ones. Conservationists are attacking the pellet industry’s green-energy luster on two fronts. They worry that the booming market for pellets will encourage industrial logging and sully the sensitive ecosystems of bottomland hardwood forests. And they counter European government carbon-cycle calculations with their own assessment that burning trees is, in the words of a British environmental group’s campaign, even “ dirtier than coal .” “It just doesn’t make sense that we’re logging the world’s forest … burning it into the atmosphere and calling it clean, green, renewable energy,” said Danna Smith of the Asheville-based Dogwood Alliance , a network of Southern conservation groups. A push toward pellets The European Union and Great Britain have adopted aggressive targets for reducing greenhouse gas emissions that contribute to global warming. They have created incentives for electric utilities to cut back on their use of coal and will require renewable sources to provide 20 percent of all energy by 2020. Wind and solar power are expected to meet only a small share of that demand. Power companies are looking to close the gap with biomass – primarily with imported wood pellets. Biomass use in Great Britain, 3 million tons last year, is expected to grow tenfold over the next five years. Britain’s biggest carbon emitter is the Drax Group, a Yorkshire utility that operates the largest power plant in western Europe. Drax is converting half its plant from coal to wood pellets. Coal is one-third the price of pellets, but Drax CEO Dorothy Thompson said her company is responding to renewable-energy credits and a British carbon tax, introduced this year at $7 a ton, that will grow by 2020 to more than $60 a ton. “And that is very substantial,” Thompson told a BBC-TV interviewer in July. “When we burn biomass, we don’t pay that. Because biomass is carbon-neutral. When we burn coal, the cost is very high.” With coastal forests close to its seaports, the South has become the top pellet source for Drax and other European utilities. Pellet makers also are taking advantage of declines in the region’s pulp and paper industry, which uses some of the same low-grade wood. Loggers in northeastern North Carolina lost their main buyer for hardwood pulpwood a few years ago when International Paper closed a mill in Franklin, Va. “We generally fill that void that was historically used by the pulp and paper industry,” Thomas Meth, Enviva’s executive vice president and co-founder, said during a tour of the Ahoskie mill. “We generally site our locations where we’ve had a lot of plant closings, to avoid most of the competition.” Enviva built on the site of a Georgia Pacific sawmill that closed in 2005. Residents of a nearby Ahoskie neighborhood say they never had problems with Georgia Pacific, but they are complaining now about noise and occasional clouds of sawdust wafting from Enviva’s pellet mill. Anne Williams, a retired hospital aide in her 70s, said she sweeps her porch once or twice a day to clean off the fine, dark sawdust that blows from Enviva across a tobacco field to her comfortable manufactured home. Dust coats cars and clogs air-conditioners in the neighborhood, she said. She keeps her windows closed. “They claim it won’t hurt you,” Williams said. “But the way it sticks to everything out there, you know it’s got to be sticking to your lungs.” Meth said Enviva has reduced the dust problem and hopes to eliminate it later this year. “We have always been within our permitted limits,” Meth said. “But in order to have a good relationship with the neighbors, we’ll take an extra step and build some extra dust protection.” Pellet makers won’t bid against sawmills for valuable timber that has higher uses, Meth said. He guided visitors through a woodlot stacked 20 feet high with treetops and whole trees, many with crooked or diseased trunks that he said make them unsuitable for saw timber. “We use by-products of the normal harvesting process in wood fiber,” Meth said. “And residues, in the broadest sense. There’s a lot misperception as to what we actually use. The value of what we take is 10, 20 percent of the whole harvest.” Carbon calculations Enviva gives delivery truck drivers a flier explaining that the company won’t accept valuable saw logs, and it rejects logs wider than 26 inches at the base. Critics say the company uses big trees that cannot be considered mere “residue.” “Their yard was not filled with log waste,” said Debbie Hammel of the Natural Resources Defense Council , looking at photos taken by environmentalists at the Enviva site earlier this year. “It was filled with whole trees. It meant that their sourcing activity has a bad carbon profile associated with it.” The carbon calculations are complicated. After the pellets from a single tree are burned, Hammel and the Dogwood Alliance’s Smith said, it takes 50 years for a replacement tree to absorb enough carbon to offset the pollution. But some economists and foresters look at this differently. They argue that a healthy demand for lumber encourages woodland owners to keep planting more trees, which will absorb more carbon from the air. A landowner unhappy with the economic return from forestry is more likely to cut down the trees and divert the land to farming or urban development. “Losing timberland to agriculture is a worse carbon story than the cycling of trees that probably would have been harvested anyway,” said Bob Abt, a forestry professor at N.C. State University. “The carbon accounting is messier than saying that the tree is going to take 50 years to replace.” Enviva said switching from coal to wood pellets reduces carbon emissions by more than 74 percent. British government standards say that pellet makers must draw only on environmentally sustainable logging sources. But Abt said he agrees with environmentalists who say “the wording there is vague.” Meth said Enviva meets the sustainable forestry standards set by professional certification organizations, including the Forest Stewardship Council. British officials say they are taking a closer look at their pellet policies. Ed Davey, the British energy secretary, recently called biomass an interim solution. “Making electricity from biomass based on imported wood is not a long-term answer to our energy needs,” Davey told the BBC. Jennette, the Windsor forester, said the new pellet market brings both economic and environmental benefits. Enviva accepts more of the logging leftovers than the hardwood paper mills did in the old days, he said. “The whole tree goes to Enviva,” Jennette said. “And the tonnage goes way up when you start doing tops and limbs and everything else.” It can be enough money to make a difference in the profitability, and the timing, of a timber sale. Jennette’s Hertford County client expects to clear about $1,000 an acre – most of it from valuable saw timber, but somewhere between $150 and $300 for those chips. Replanting will be easier, too, he said. “As clean as this site will be, we’re able to reforest for less money,” Jennette said. “As long as we reforest what we cut and we do a good job of the sustainability piece of it, we’ll never stop.” Continue reading
