UK Government Sets Biomass Power Rules
Electricity from biomass is expected to save 70% of greenhouse gas emissions 22/08/2013 UK government sets biomass power rules Financial support only available if sustainable Helen Tunnicliffe THE UK government has set new sustainability criteria for biomass to ensure that it contributes effectively to the country’s emissions reduction targets. Electricity from biomass is expected to save 70% of greenhouse gas emissions compared to fossil fuels, but concerns have been raised that some of the wood chips and pellets used in biomass power stations is no better than coal and in some cases worse if it has been harvested in an unsustainable way, from a badly-managed plantation or shipped from thousands of miles away. The new standards announced by the Department for Energy and Climate Change (DECC) are designed to address these concerns and apply to all companies generating 1 MW or more of energy from solid biomass or biogas which are claiming financial support under the Renewables Obligation (RO). The RO means that all generating companies must source a set proportion of their electricity from renewable energy, but receive a premium for doing so. From April 2015 onwards, electricity generating companies could face losing these financial incentives if they cannot prove that the biomass fuel for their plants meets the tough new standards. The sustainability criteria look at the way the source forest is managed, including ensuring that harvesting rates are sustainable, that biodiversity is protected and that indigenous populations retain their land use rights. DECC has also pledged not to make any more changes to the sustainability criteria before April 2027. Greg Barker, the minister of state for energy and climate change says that biomass is an important part of the UK’s energy mix. “The new criteria will provide the necessary investor certainty and, crucially, ensure that the biomass is delivered in a transparent and sustainable way,” he adds. The news has been welcomed by the Renewable Energy Authority (REA), which represents UK companies in the renewable energy industry. “These sustainability criteria ensure that the UK can reap the benefits of biomass, safe in the knowledge that it is making a real dent in our carbon emissions and that ecologically sensitive land is being protected. Biomass is a great way to bridge the looming capacity gap because it has all the same benefits as fossil fuels, such as reliability and flexibility of supply, but without the carbon impacts,” says REA CEO Nina Skorupska. The REA, however, warned that all biomass generation must be supported by the government. Earlier this month, RWE closed its Tilbury power station in the UK, which it had been converting from coal to biomass, when the government withdrew subsidies under the Contracts for Difference scheme which invests in low carbon technologies. Only combined heat and power (CHP) projects are now eligible for subsidies under this scheme, but REA points out that many otherwise suitable sites have no users for the heat generated.

Biomass Loopholes ‘Big Enough To Drive A Logging Truck Through’
Posted on 27 August 2013 by Tom Grimwood Green campaigners have attacked the revised sustainability criteria for the UK’s burgeoning biomass electricity industry. The Department of Energy and Climate and Change (DECC) says its “tough” new demands will mean biomass-fuelled generators must hit targets on how much carbon is emitted and whether enough trees have been replanted, with rules kicking in from April 2015. But the new rules have taken flak from several environmental groups. Biofuelwatch claimed most of the carbon emissions from biomass will be ignored because DECC’s sustainability criteria exclude things like ‘substiution’ emissions – the carbon cost of burning biomass which could have had other uses. The group said DECC relies on a number of “dubious” schemes to certify sustainability and described the Ofgem carbon calculator they use to tot up greenhouse emissions as “deeply flawed”. A spokesman for Biofuelwatch, Duncan Law said: “DECC is more concerned with ‘keeping the lights on’ using existing technology than with real carbon savings and environmental impact. It is heavily lobbied by the energy companies who stand to make hundreds of millions from burning hundreds of millions of tonnes of imported wood.” Greenpeace also attacked DECC’s failure to mention ‘carbon debt’. They quoted a report by the European Environment Agency which found that burning biomass can be actually be a high carbon source of energy if forests aren’t re-grown to pay the ‘carbon debt’ back. Dr Doug Parr, the Chief Scientist at Greepeace said: “The loopholes in these sustainability standards are big enough to drive a logging truck through. Having learnt nothing from the biofuels debacle, the Government has ignored the latest scientific research and produced standards that will take a potentially sustainable industry and transform it into one more way to greenwash environmental destruction.” But the Renewable Energy Association (REA) said these arguments are based on worst-case scenarios involving the burning of whole trees and unsustainable forest management, when the industry mainly relies on cheaper leftovers. REA Chief Executive Dr Nina Skorupska said: “These sustainability criteria ensure that the UK can reap the benefits of biomass, safe in the knowledge that it is making a real dent in our carbon emissions and that ecologically sensitive land is being protected.” Continue reading
New Regulations Create Fresh Row Over Biomass Power
Government guidelines could allow destructive forms of biomass and fail to satisfy industry of future financial support Fiona Harvey , environment correspondent theguardian.com , Thursday 22 August 2013 15.34 BST The travails of the industry were highlighted in July with the shelving of plans to turn the Tilbury power station into a biomass-burning plant. Photograph: Alamy[/color] New regulations to ensure energy generated from forests, crops and waste is sustainable provoked a fresh row on Thursday over biomass power, with the government plans failing to reassure the industry of future financial support. Green campaigners said the new rules would allow the use of destructive forms of biomass, which have been linked to deforestation in other countries. The biomass industry denied this, but will still face a major task to attract investment into the sector, because the government has put strict limits on how biomass plants will be supported under its new regime for the electricity market. Under the current proposals, biomass will be at a disadvantage relative to other forms of generation, because some forms of new biomass power plants will be effectively excluded from the new long-term “contracts for difference” that are the basis of the new system. That may rattle investors. The travails of the industry were highlighted in July with the shelving of plans to turn the Tilbury power station, in Essex, into a biomass-burning plant. Greg Barker, minister for energy and climate change, said biomass – now an industry worth £1bn in the UK and supporting 3,000 jobs – had “an important role” in UK energy generation. “The new criteria will provide the necessary investor certainty and ensure that the biomass is delivered in a transparent and sustainable way.” The new sustainability rules cover issues such as harvesting rates, to ensure trees can regrow, as well as ensuring wood comes from forests where the biodiversity is not harmed by the harvesting, and where the rights of indigenous people are respected. The government promised there would be no changes to the criteria before 2027, and that the operators of plants who complied with the guidelines would continue to receive subsidies under the Renewable Obligation. Dr Nina Skorupska, chief executive of the Renewable Energy Association, which represents the industry, said: “These sustainability criteria ensure that the UK can reap the benefits of biomass, safe in the knowledge that it is making a real dent in our carbon emissions and that ecologically sensitive land is being protected.” Tensions between green groups and the biomass industry have been running high for months, as environmental groups have published studies and claims that some forms of biomass, such as imported wood, do not reduce carbon dioxide emissions because they encourage the chopping down of large swaths of forest. Biomass proponents have responded that some of the scientific research has been misinterpreted , and unrealistic worst case scenarios wrongly presented as the norm. At least one academic involved with the research has contested the green groups’ claims. However, the government’s new guidelines, far from defusing the row, have inflamed it further. Dr Doug Parr, chief scientist at Greenpeace UK, said: “The loopholes in these sustainability standards are big enough to drive a logging truck through. The government has ignored the latest scientific research and produced standards that will take a potentially sustainable industry and transform it into one more way to greenwash environmental destruction. The climate isn’t going to fall for creative accounting and neither should the public.” The government also failed to satisfy the biomass industry with Thursday’s announcement. Under electricity market reform, new biomass-burning power stations will only qualify for the new contracts if the heat they produce is captured and reused, a process known as combined heat and power (CHP). But some biomass companies are worried because CHP technology is an extra cost at the outset, and because it is only suitable where there are buildings – either dwellings, industrial estates or large public buildings – near enough for the heat to be piped from the plant. Given the UK’s planning laws, it may be hard to get permission for a site, which could put some potential projects in a “catch-22” situation. CHP will also only be economically viable if nearby property owners are prepared to pay for the heat. Skorupska said biomass was a good option because it could reduce carbon, but is not intermittent like other renewables such as wind. But she warned that the CHP stipulation risked harming investment. “CHP is an excellent use of the resource, but it is not feasible in sites where there is no user for the heatload. The government will have serious regrets down the line if it excludes the construction of dedicated biomass power plants from the new regime.”[/font][/color] Continue reading
