Biomass: Head To Head Debating Pros And Cons
Is biomass a viable part of the future energy mix, or is it part of the carbon emissions problem? Eoin Redahan asked two industry experts. Stewart Boyle (SB) runs the consultancy arm of South East Wood Fuels Duncan Law (DL) represents Biofuelwatch, an NGO that raises awareness of the negative impacts of industrial biofuels and bioenergy. Stewart Boyle The pro biomass perspective – SB I spent 18 months on research into the potential and reality of bio-energy in the UK. Its advantages are real, in that it provides versatility (offering heating, cooling, power generation, transport fuels and bio-chemicals), reliability (no problems with intermittency), and is sustainable and cost-effective. It could provide 10–20% of our energy by 2030–2040 – three times the output of nuclear power. Bio-energy is a critical renewable option in allowing the clear transition to lowcarbon hybrid vehicles, de-carbonising power and shifting to green gas. To achieve its potential we need a significant effort to educate, show how it offers an integrated energy solution, and argue head-on the bad science arguments being used against it. From a support position five years ago, many environmental NGOs now oppose biofuels, pure biopower and co-firing. One NGO, Biofuelwatch, says bio-energy leads to forest destruction – witness its attitudes on palm oil and kernels for biofuels – and suggests that Drax (the UK’s largest power station, which co-fires biomass) mostly uses old growth forest from North America. This is utter tosh and the Drax team should be applauded, not criticised, for its cradle-to-grave sustainability system. I spent a big chunk of my earlier life working for several NGOs. However, I think many are biased, use bad science and have lost the plot on bio-energy. Duncan Law The anti biomass perspective – DL Under the guise of renewable energy and carbon saving, burning wood in power stations is a massive growth industry in the UK right now. Huge old coal power stations such as Drax are getting UK Government subsidies to burn millions of tonnes of imported wood at 37% efficiency, but can only use good quality wood with low bark content – not pure forest wastes. Burning wood emits even more carbon than burning coal for a given amount of energy generated (especially when whole trees are used). Forests take up to a century to absorb as much CO2 as is emitted when they are burned. So emissions will actually rise. The DECC now acknowledges that burning biomass in dedicated power stations offers poor-value carbon savings compared with wind power or even gas. Yet they offer huge subsidies. Current UK biomass burning plans are projected to demand nearly the entire global biomass trade by 2025. Most of it currently comes from the USA and Canada where biodiverse, old-growth forests are being clear felled and replaced with monoculture tree plantations. Biomass also produces more small particulate pollution than coal, which can have grave public health impacts. Minister Ed Davey, UK Secretary of State for Energy and Climate Change, said, ‘Making electricity from biomass based on imported wood is not a long-term answer to our energy needs – I am quite clear about that’. Biomass is not an answer. It pollutes, is costly, inefficient, does not contribute to UK energy security, damages biodiversity and forests, and makes climate change worse. SL: I disagree with virtually all of Duncan’s comments on bioenergy. Take the carbon debt issue – the supposed scientific basis of much NGO opposition. Duncan says, ‘Forests take up to a century to absorb as much CO2 as is emitted when they are burned’. In my opinion, this is misleading. While cutting and then replacing a single tree or small stand of trees will take some time for the CO2 to be absorbed, guess what? Foresters know that. A well-managed forest has a wide range of trees – some mature and ready for felling, others in mid-growth and absorbing lots of CO2, plus newly planted trees. When DECC researchers looked at the issue, they concluded, ‘Providing forest stands are re-established as soon as they are clear-felled, overall carbon stocks in the forest are not reduced [no carbon debt is incurred]. Rather, a constant carbon stock is maintained over time.’ Using low-quality wood materials that have no competing uses, Drax clearly demonstrates substantial carbon savings of well over 70%. That Drax ‘mostly’ uses wood from clear-felled old growth forests is simply not true. Duncan references this from a single BBC radio programme, but any independent audit of Drax’s biomass materials would refute the suggestion. No one argues that co-firing is the end game. Other technologies are coming fast. It does, however, offer reliable, lower-cost carbon reductions quickly to gain momentum and investment into this and second-generation technologies. Arguing for perfection now in bio-energy will kill off key solutions to our climate crisis and invite in shale gas, nuclear and extreme oil. DL: Biofuelwatch has been working for seven years on this issue. We follow the plot of the bioenergy industry closely. To counter just one of Stewart’s specific assertions – Drax bases its optimistic 70% carbon savings from biomass on using ‘forest wastes that would simply be burnt in the forest’ (Paul Taylor, Drax Director). Freedom of Information evidence shows they can only use wood from slow growing trees that have a low bark content. Drax is using pellets from whole trees. Dogwood Alliance (a forest protection network) has documented clear-felling of old-growth forest for the energy industry. Peer-reviewed evidence shows that rates of global forest cover loss in southeast USA are among the highest globally. Conversion to tree plantations causes huge emissions. All this equals carbon debt. The impossibility of real sustainability assessment in the biomass industry is documented in a Biofuelwatch report. Vast Government subsidies and the Green Investment Bank loan to Drax extend the coalburning life of this plant by years. And the biomass will increase, not reduce, its real carbon emissions. Biomass is the easy option for the Government and industry to avoid a supply crunch and keep the lights on by using existing technologies. The vast ambitions of the bio-energy industry disregard unintended consequences. It is set to expand in a way that is dangerous and unsustainable. Biofuelwatch opposes big bioenergy because the impacts are unacceptably dangerous, both in terms of current carbon emissions and damage to the planet’s life support systems. It is a distraction from rethinking our demand and our energy systems for a real low-carbon future. Both speakers referred to different sources to back up their statements.

Foreign Investment In Agriculture? How About A Plan For Profitability
Perhaps talking about investment could lead Australia to a brighter farming future. Michael Lloyd Large parts of Australian agriculture are economically and financially unsustainable . Returns are inadequate and unbalanced; assets are depleted; risks are needlessly high. To date, governments have largely relied on the market to address problems, but problems have worsened. Mainstream political thinking has essentially ignored issues of foreign investment in farming and food processing (where no significant wholly Australian processor remains). Popular opinion has been turning against such investments, but it was only on Wednesday evening, at the Rooty Hill leaders debate, that prime minister Kevin Rudd finally stated his anxiety about our “ open slather approach ” and expressed the need for change. Responding, opposition leader Tony Abbot was reassuring. He would lower the threshold for review of foreign investment from A$220 million to A$15 million – a meaningless gesture when approvals are automatic and asset overpricing pressures remain unchecked. Understandably he did not wish to open up an issue that still divides those in the Coalition and, now openly, Labor . Headline reactions were splendid: Rudd “retreats on foreign investment” (AFR), “risks foreign investment” ( The Australian ), “takes hard line on foreign investment” ( The Land , The Conversation ), “cautious on foreign investment” and makes “reckless flub on foreign investment” (both Business Spectator). Tidying up after this explosive “thought bubble” preoccupied most. All in all, it was a marvellous media moment for reporting, little analysis and much opinioneering. How important is foreign investment to our farming future, and indeed our nation? Briefly, the historical record is mixed. There are no clear connections between GDP growth and foreign investment, and indeed some contrary examples (relatively slow GDP growth with high foreign investment). The really important issue is how investors use production assets (such as farmland) and who profits where and when. Serious problems arise in markets when: income streams and profit are inadequate for needs distorting opportunistic strategies are not curbed or countered assets from stressed enterprises are dumped on markets investments are made with mixed motivations funding availability and power are asymmetric financing is unevenly based and biased and perceptions are distorted by misinformation. Any one of these conditions can corrupt asset markets. As all seven are evident in the Australian farmland and product markets, outcomes are likely to be perverse. Relying on a market solution in such circumstances would be foolish, something that the current prime minister seems to be realising, finally. Not business as usual While our politicians and, particularly, their advisers might prefer “Plan A: business as usual”, prudence dictates planning for realities. Here the Australian people are ahead, with now clearly expressed preferences for controls on farm land purchases, supply chain reform, robust national interest evaluations and the like. This year has witnessed many collapses in rural businesses across all manner of size and form, with many more likely. Governments need to agree on an adequate “Plan B: Stabilisation” as a debt-deflation spiral builds in rural land assets. In our open economy, the build-up in foreign investment necessitates “Plan C: asset return enhancement”. Foreign investment, be it direct or portfolio, can add significantly to the progress of regions and a nation when it adds something “new” or “better” that realises decent returns for both its domestic hosts and external investors. Foreign capture of assets, however, is different. There, not only do the bulk of returns accrue preferentially to external parties. Control of assets also enables wider strategies, be these corporate or national. For example, a grain handler (headquartered in the USA, China, Middle East or elsewhere) may acquire assets in Australia not so much for the earnings from a well-run business based on them but as a means of global supply chain consolidation and targeted preferencing of some suppliers (and discrimination against others). Plan C should then minimally include a robust national benefit demonstration and measures to preclude opportunistic actions. Under some circumstances (such as current high domestic finance costs and limited rural liquidity) the only real national solution appears to be to ban foreign investment until local investors can obtain comparable finance. Currently cheap foreign money is maintaining unserviceably high asset values and privileged asset access, pushing prices above those local investors can sensibly afford. The critical strategic question is how to manage foreign investments so that excessive domestic production earnings do not leave the country (as already happens in some Australian sectors and many parts of the world). This is central to plan “D: Restoring national incomes”. Ownership transfer, income losses Further ownership transfers of farm, processing, product handling and marketing assets to external parties would see increasingly serious national income losses and Balance of Payment deterioration. Australia is an increasingly indebted nation. It needs to earn its way in the world, not sell off the assets which could support such earnings. External crises can be expected soon enough if our annual net outflows of around A$50 billion continue to go unaddressed. The usefulness of current financing arrangements could be the focus of “Plan E: sustainable finance”. Currently banks are providing what are essentially home loans to businesses with the high income volatility of agriculture. Others have structured finance in unsustainable ways. All have been asking for trouble, and it has now arrived. High interest rates (especially the growing margin claimed by financiers for rural funds and the use of unilaterally-imposed penalty rates) need attention, as do the situations of larger debt holders. A well-constituted Rural Reconstruction and Development Bank is part of a viable solution. Next come “F: supply chain operation”. This does not just mean the problems laid at the door of Woolworths and Coles. The real issue is one of supply chain closures, globally and nationally, as countries and corporations set up their own exclusive supply chains. Markets are increasingly bypassed as corporations tie up chains for a variety of reasons. Such chains are tailored to preferentially serve certain parties at select parts of the chain. As this runs from farmers through transport and processing to end users anywhere in the world, there are many options for predatory, security or other actions. Recall that high prices only five years ago saw more than 30 nations enact food export controls to ensure their domestic populations were fed. Insightful action needed Ultimately, solutions combine in “Plan P: restoring enterprise profitability”. Suitably profitable enterprises have futures. Opportunities to develop can then be sensibly taken up. Much distress and needless destruction of wealth can be avoided if we act insightfully, now. In all, new policy directions that canvas a range of possibilities for these uncertain times are needed. Solving serious problems in rural Australia requires focused, informed and creative responses by involved stakeholders. Unfortunately, current policy proposals are out by an order of magnitude – and many are not even on the right track . Prompt, effective interventions can halt the deteriorating situation of Australian farm assets, and the national slide. Complementary actions can restore profitability. Such is the challenge to those who would lead us. Continue reading
Biofuels ‘Will Meet RFS Mandates Through 2016’
September 3, 2013 There will be sufficient supply of advanced biofuels to meet the US Renewable Fuel Standard through 2016, according to Environmental Entrepreneurs’ (E2) annual assessment of the advanced biofuel industry . The report comes amidst renewed scrutiny of the RFS from Congress this summer, as the oil industry seeks to roll back the renewable fuel requirements . The RFS requires that the majority of future growth in biofuels production come from non-food cellulosic biofuels, and the slower than expected commercialization of the cellulosic industry has caused some to lose patience with the program, E2 says. The report suggests that the policy is beginning to deliver on its stated purpose of developing a domestically produced, clean-burning alternative to oil. The assessment says advanced biofuels capacity for 2013 is 1 billion gallons gasoline equivalent while capacity for 2015 is between 1.4 and 1.6 billion gallons gasoline equivalent. Additionally, Some 160 commercial scale facilities planned, under construction, or complete from 159 companies and private investment in the advanced biofuel industry totals over $4.85 billion since 2007. Federal loan guarantees exceed $1.1 billion since 2008, the report says. Nine of the current biorefinery projects have received these loan guarantees. To qualify as advanced for the E2 report, a biofuel must deliver at least a 50 percent reduction in carbon intensity compared to petroleum using calculations developed by the California Air Resources Board. Biodiesel remains the dominant advanced biofuel today and is expected to remain the forerunner through 2016. So-called drop-in fuels show significant progress and the report authors expect them to contribute more substantially to overall advanced biofuel capacity over time. The EPA, which administers the RFS, is expected to announce biofuel volume requirements for 2014 sometime over the next month. And while the report shows that the biofuels industry can meet near-term production targets, even under the best circumstances, advanced biofuels can account for only 0.7 percent of US fuel demand — suggesting that while biofuels can be part of efforts to cut oil use, they must be paired with other solutions such as expanded electric vehicle use and greater fuel efficiency, E2 says. California is ahead of the biodiesel curve , according to a study published last month by E2 and Environmental Defense Fund. Growing production in the state shows California companies have started capitalizing on this low-carbon fuel. Companies profiled in the report credit California’s Low Carbon Fuel Standard (LCFS), which calls for lower emissions from transportation fuels, with driving demand for and growth of biofuels in the state.
