Private forest owners' willingness to supply woody biomass in selected South-Eastern European countries

Production of woody biomass-based energy, mainly by using fuel wood, is a common way of forest utilization in selected South-Eastern European countries – Croatia, Bosnia-Herzegovina, Serbia and Former Yugoslav Republic of Macedonia. Due to specific forest ownership patterns in the region, state owned forests are the most important source of all forest assortments, including woody biomass. Having in mind the increasing energy needs on the global scale, particularly those for energy from renewable sources, private forests may play an important role in terms of wood mobilization and energy production from woody biomass. The purpose of this research was to identify the willingness of private forest owners in selected countries to supply woody biomass for energy as well as to identify the factors that influence it. The survey data collected in 2012 from 1.400 private forests owners (random samples of 350 private forests owners in each of the four countries), show a relatively high degree of willingness (38–55% of the respondents) to manage their forests in order to produce woody biomass. Furthermore, the results, demonstrated that the willingness of private forest owners to supply woody biomass was namely influenced by age in analysed countries. The models found that relatively younger owners were more likely to supply woody biomass. An adequate institutional and financial support to private forest owners and the designing of an appropriate mix of forest policy instruments are necessary for a better wood mobilisation and the triggering of woody biomass supply from private forests in selected South-Eastern European countries.     

World trade in forest products and wood fuel

Wood fuel is a strategic resource for future energy supply and is usually utilised locally. Traditional use of wood fuel and other bioenergy has a share of 10–15% energy supply, used mainly for the household sector. The utilisation for industrial purposes is much smaller but is a strategic resource in the effort to fulfil the Kyoto agreement to replace fossil fuels and to mitigate greenhouse gas emissions. Many industrialised countries already use a significant share of biofuels in their energy supply e.g. Nordic countries while others like some other European Union countries are planning to increase their use. Production and use of biofuels need to be carried out sustainable. Official statistics do not report trade in such detail that international trade in different biomass types can be fully identified. However, FAO and European Forestry Institute are important sources. In some countries, there is a growing interest in the international trade, because the trade can provide biofuels at lower prices, larger quantities and better quality than domestic alternatives. The first signs of an international market price for wood fuel are indicated in Europe. For the future both the use and the trade of wood fuel is expected to increase. Analyses for trade in charcoal, wood chips, fuel wood and wood residues made in this report identify ‘hot’ trade spots in Europe, in south East Asia and in North America.     

Forest biomass and Armington elasticities in Europe

The purpose of this paper is to provide estimated Armington elasticities for selected European countries and for three forest biomass commodities of main interest in many energy models: roundwood, chips & particles and wood residues. The Armington elasticity is based on the assumption that a specific forest biomass commodity is differentiated by its origin. The statistically significant estimated Armington elasticities range from 0.52 for roundwood in Hungary to approximately 4.53 for roundwood in Estonia. On average, the statistically significant Armington elasticity for chips & particles over all countries is 1.7 and for wood residues and roundwood 1.3 and 1.5, respectively. These elasticities can provide benchmark values for simulation models trying to assess trade patterns of forest biomass commodities and energy policy effects for European countries or for the EU as a whole.     

Electricity from biomass in the European union—With or without biomass import

The European Union has set up indicative targets for its 15 Member States to supply 22.1% of their total electricity consumption using renewable energy resources by 2010. This paper compares two ways to achieve target compliance—either with import of biomass from countries outside the EU or without. The ADMIRE REBUS model combines cost data for electricity producing renewable energy technologies with data on the renewable energy resources available in EU and assesses the effect of the various national support policies for green electricity in the EU countries. The major finding of the study is that increased imports of low-cost biomass will significantly reduce the cost of target compliance, but would hamper the use of energy crops and further development of wind power within the EU. Despite this, increased importation of biomass can be the cost-reducing factor making the target realisable, which would justify promotion of such trade.     

Review of technology in small-scale biomass combustion systems in the European market

This work studied the importance of wood pellets, chips and wood logs for small- and medium-scale heat production. Pellet use can contribute substantially to reaching the renewable heat and electricity goals set by the European Union (EU) Renewable Energy Directive. Consequently, to integrate into European energy markets, pellet use must be a key piece of the EU energy policy.This study provides a wide perspective on the state-of-the-art small-scale biomass combustion units, particularly those that use pellets for fuel. Small-scale combustion units include stoves and boilers with capacities less than 200 kW. A wide market review has been conducted, including a review of the literature and information from manufacturers and test institutes. A database has been created, which includes 186 companies and offers 995 different models, providing an extensive view of the European market. The large number of new companies shows that the solid-fuel boiler market is continuously increasing across Europe. The technologies that are currently the most widely used are described and compared.     

Forest owner motivations and attitudes towards supplying biomass for energy in Europe

The European Commission expects the use of biomass for energy in the EU to increase significantly between 2010 and 2020 to meet a legally binding target to cover at least 20% of EU's total energy use from renewable sources in 2020. According to estimates made by the member states of the EU, the direct supply of biomass from forests is expected to increase by 45% on a volume basis between 2006 and 2020 in response to increasing demand (Beurskens LWM, Hekkenberg M, Vethman P. Renewable energy projections as published in the national renewable energy action plans of the European Member states. ECN and EEA; 2011. http://https://www.ecn.nl/docs/library/report/2010/e10069.pdf [accessed 25.04.2014]; Dees M, Yousef A, Ermert J. Analysis of the quantitative tables of the national renewable energy action plans prepared by the 27 European Union Member States in 2010. BEE working paper D7.2. Biomass Energy Europe project. FELIS – Department of Remote Sensing and landscape information Systems, University of Freiburg, Germany; 2011). Our aims were to test the hypotheses that European private forest owners' attitudes towards supplying woody biomass for energy (1) can be explained by their responses to changes in prices and markets and (2) are positive so that the forest biomass share of the EU 2020 renewable energy target can be met. Based on survey data collected in 2010 from 800 private forest owners in Sweden, Germany and Portugal our results show that the respondents' attitudes towards supplying woody biomass for energy cannot be explained as direct responses to changes in prices and markets. Our results, furthermore, imply that European private forest owners cannot be expected to supply the requested amounts of woody biomass for energy to meet the forest biomass share of the EU 2020 renewable energy target, at least if stemwood is to play the important role as studies by Verkerk PJ, Anttila P, Eggers J, Lindner M, Asikainen A.

Five years left – How are the EU member states contributing to the 20% target for EU's renewable energy consumption; the role of woody biomass

The European Union has set ambitious targets of raising the share of EU energy consumption produced from renewable resources from 20% by 2020 to 27% by 2030. The aim of this paper is to assess the role of woody biomass in renewable energy as gross final energy consumption in the European Union (the EU-28). The paper identifies leading and lagging countries in biomass development by focusing on their current biomass use and forecasts future perspectives. The research compares and evaluates the role of biomass in renewable energy in the EU-28 focusing on countries' potential resources and policy support. The study shows that all countries are making efforts to reach the 20% target in 2020 and exhibit a trend of increasing renewable energy as gross final energy consumption towards the new target of 2030. Solid biomass plays an important role in reaching the EU's renewable energy targets. The majority of the EU-28 countries are close to reaching their national renewable energy targets and show a very attractive biomass development. Unless energy consumption decreases however, some member states will face serious problems in reaching their renewable energy target in 2020. Following our analysis, the largest problems occur in those MS having a relative high-energy consumption pattern: France, Germany and the United Kingdom. It is unlikely that they can comply with expected renewable energy demand, unless they mobilize more woody biomass from their available domestic potential (France, Germany) or considerably increase their woody biomass imports (mostly wood pellets) from elsewhere (United Kingdom).     

Sustainable utilisation of forest biomass for energy—Possibilities and problems: Policy,legislation, certification,and recommendations and guidelines in the Nordic,Baltic, and other European countries

The substitution of biomass for fossil fuels in energy consumption is a measure to mitigate global warming, as well as having other advantages. Political action plans for increased use exist at both European and national levels. This paper briefly reviews the contents of recommendations, guidelines, and other synthesis publications on sustainable use of forest biomass for energy. Topics are listed and an overview of advantages, disadvantages, and trade-offs between them is given, from the viewpoint of society in general and the forestry and energy sectors in particular. For the Nordic and Baltic countries, the paper also identifies the extent to which wood for energy is included in forest legislation and forest certification standards under the “Programme for the Endorsement of Forest Certification” (PEFC) and the “Forest Stewardship Council” (FSC) schemes. Energy and forest policies at EU and national levels, and European PEFC forest standards are analysed. With respect to energy policies, the utilisation of wood for energy is generally supported in forest policies, but forest legislation is seldom used as a direct tool to encourage the utilisation of wood for energy. Regulations sometimes restrict use for environmental reasons. Forest certification standards include indicators directly related to the utilisation of wood for energy under several criteria, with most occurrences found under environmental criteria. Roles and problems in relation to policy, legislation, certification standards, recommendations and guidelines, and science are discussed.     

Assessment of wood fuel use for energy generation in Lithuania

The paper investigates possibilities to use solid biomass (wood) resources. It provides detailed analysis on distribution of Lithuanian wood resources and evaluates possibilities to develop the use of above resources for heat and power generation. European Union as well as Lithuanian legislation declares promotion measures for wood as fuel for energy generation. Legal documents suggest implementation via subsidizing of raw material for production of wood chips for boiler-houses and adopting specific promotion program for the use of forestry biomass for boiler-houses according to which the difference between price and costs should be subsidized for producers of such raw material.Directive 2009/28/EB obligates separate countries to develop National Renewable Energy Action Plans (NREAP), which would provide specific promotion schemes and target indicators for each year (up to year 2020). According to this Directive the EU RES share in final energy consumption should reach 20%, and for Lithuanian this share should be no less than 23%, while district heating systems should use no less than 70%. At present the total capacity of wood-chip-fueled boilers reached above 476.1 MW. No series obstacles can be seen for extension of wood fuel use. The renewable energy compromise 18.1% of primary energy annual gross inland consumption and cut of the CO₂ emissions about 6% compared with the level on 1990. According to the Kyoto Protocol Lithuania must reduced green gas emissions 8% in the period 2008–2012. These goals can be realised by increasing of the use of biomass as fuel for the energy production.     

EUBIONET III—Solutions to biomass trade and market barriers

The EUBIONET III project has boosted (i) sustainable, transparent international biomass fuel trade, (ii) investments in best practice technologies and (iii) new services on biomass heat sector. Furthermore, it identified cost-efficient and value-adding use of biomass for energy and industry. The aims of this article are to provide a synthesis of the key results of this project. Estimated annual solid biomass potential in the EU-27 is almost 6600 PJ (157 Mtoe), of which 48% is currently utilised. The greatest potential for increased use lies in forest residues and herbaceous biomass. Trade barriers have been evaluated and some solutions suggested such as CN codes for wood pellets and price indexes for industrial wood pellets and wood chips. The analysis of wood pellet and wood chip prices revealed large difference amongst EU countries, but also that on the short term prices of woody and fossil fuels are barely correlated. Sustainable production and use of solid biomass are also deemed important by most European stakeholders, and many support the introduction of harmonised sustainability criteria, albeit under a number of preconditions. The study identified also that a number of woody and agro-industrial residue streams remain un- or underutilised. The estimated European total potential of agro-industrial sources is more than 250 PJ (7.2 Mtoe), the amount of unutilised woody biomass (the annual increment of growing stock) even amounts to 3150 PJ (75 Mtoe). Finally 35 case studies of biomass heating substituting fossil fuels were carried out, showing that the potential to reduce GHG emissions ranges between 90 and 98%, while costs are very similar to fossil fuel heating systems. Overall, we conclude that solid biomass is growing strongly, and is likely to heavily contribute to the EU renewable energy targets in the coming decade.     

Interest in energy wood and energy crop production among Finnish non-industrial private forest owners

EU targets and regulations regarding energy production and the reduction of greenhouse gas emissions have been tightening in the 2000s. In Finland the targets are planned to be achieved mainly by increasing the use of biomass. Wood already accounts for a marked proportion of Finnish energy production, but additional reserves are still available. Energy crop production also has considerable potential. Practically all Finnish farmers are also forest owners. Therefore, private forest owners are in a decisive position regarding the supply of energy wood and crops in Finland. In this paper the future supply of biomass is examined according to their past behaviour, intentions and attitudes. Finnish forest owners have a positive attitude towards the use of wood and crops in energy production. Price is becoming more critical as a motive for the supply of energy wood. Recreation and nature conservation play a smaller role than factors related to wood production and forest management as for motives for harvesting energy wood. However, almost a half of forest owners in this study were uncertain of their willingness to supply biomass. This is partly due to limited knowledge of the issues involved in energy wood and agricultural energy crop production and the underdeveloped markets for energy biomass. In order to achieve the targets, supply should be activated by further developing market practices, information, guidance and possibly other incentives for landowners. In general, there is interest among landowners in increasing the supply of energy biomass. However, the growth of supply presumes that production is an economically attractive and competitive alternative, that the markets are better organized than at present, and that more comprehensive information is available about bioenergy and biomass markets and production techniques.     

Factors driving the development of forest energy in Finland

Renewable energy sources play an important role in the Finnish energy and climate strategies which are implemented partly through the Action Plan for Renewable Energy Sources. Enhancement of wood energy plays a key role in the plan. A special emphasis is given to forest chips produced from small-sized trees from early thinnings and above-ground and below-ground residual biomass from regeneration cuttings. The production goal of forest chips is 5 million m³ solid (10 TWh) in 2010. The use of forest chips is promoted by means of environmental taxes, financial aid for investments, and financial support for research, development and commercialization of technology. In 2002, altogether 365 heating and power plants larger than 0.4 MW used forest chips. The total consumption was 1.7 million m³, the use of small houses and farms included. The growth of use is presently about 350 000 m³ per annum, but reaching the official goal will require an annual growth of 400 000 m³ during this decade.The consumption of roundwood per capita, 15 m³ per annum, is in Finland 20 times as high as the average consumption of the EU countries, respectively. Consequently, residual forest biomass is abundantly available. The capacity of heating and power plants to use forest chips is large enough to meet the goal. However, users require competitive chip prices, good quality control of fuel and reliable supply chains, and new efficient procurement systems are being developed. The paper deals with the drivers of this development: support measures of the Government; strong support to research, development and commercialization of forest chip production from the National Technology Agency Tekes; advanced infrastructure for the procurement of timber for the forest industries; positive attitude and active participation of the forest industries; the active role of leading forest machine and boiler manufacturers, and the possibility to cofire wood and peat fuels in large fluidized bed boilers so as to secure the availability of fuel in all conditions, stabilize the moisture content of fuel and reduce the emissions from combustion.     

Promotional policy and perspectives of usage renewable energy in Lithuania

The article outlines renewable energy (RE) sources according to the energy efficiency policy in Lithuania as well as practical experience of implementation of RE projects within the framework of the government policy to promote RES use due to the requirement of the European Union. The main goal of the country is to reduce the import of fossil fuel, to improve environment conditions and to reduce the climate change impact. Analysis of implemented RE projects and forecasts for the future projects are also presented. Most of the efforts in Lithuania were aimed at drafting the biomass (wood chips, wood waste, straw, biogas) and small hydro projects and their subsequent implementation. At present the total capacity of wood-chip-fuelled boilers reached above 251 MW. No serious obstacles can be seen for the extension of wood fuel use. At present, new demonstrational projects have been started covering geothermal energy, solar energy, biogas, biofuels for transport and other. In this time, the RE sources comprise 7.69% of national energy balance. Taking into account feasible resources of RE (it is more than 19.85 TWh/year) and the ongoing implementation of projects it is clear that the share of RE sources will constitute 12–13% of national energy balance in 2010 year. The main factor limiting further growth is high investment costs. The electricity production from local and RE sources in Lithuania is mainly based on hydro energy. At this time the wind energy is not used for this purpose. The electricity production from local and renewable energy sources is about 3.22% of the total consumption.     

Establishment needs for short rotation forestry in the EU to meet the goals of the commission’s White Paper on renewable energy (November 1997)

A quantitative analysis is given of the consequences of the recent EU White Paper on a strategy for renewable energy sources, by matching the woody biomass demand and supply by the forest industries and the energy sector in Europe in 2010, following the 5th European Timber Trends Study approach. An annual shortage of 229 million m³ of roundwood equivalents has been identified, which can be supplemented by the establishment of 11.5 million hectares of short rotation forestry systems. However, if 50% of available agricultural residues in Europe (such as straw) were used for bio-energy purposes, then the additional biomass needs are reduced to 101 million m³ of roundwood equivalents per annum, requiring the establishment of 5.1 million ha of dedicated energy crops.     

Proposal for territorial distribution of the EU 2020 political renewable energy goal

This article first analyses the situation of indicators related to renewable energies in the reference year (2005) used by the European Union (EU) for its goal of a 20% share of energy from renewable sources in the gross final consumption of energy in 2020. Nonlinear distribution of dynamic targets is suggested for increasing the energy from renewable sources in gross final consumption of energy. This methodology is then applied to European Union member countries, the NUTS0 territorial aggregation level according to the EUROSTAT Nomenclature of Territorial Units for Statistics (NUTS), in the year 2020. Weighting was done based on share of energy from non-renewable sources in gross final consumption of energy, energy from non-renewable sources per capita, energy from non-renewable sources per GDP and GDP per capita in the EU-27 scenario. Finally, a multicriteria formula was applied to weight the variables used in this study.     

Co-firing biomass with coal for electricity generation—An assessment of the potential in EU27

The European Union aims to increase bioenergy use. Co-firing biomass with coal represents an attractive near-term option for electricity generation from renewable energy sources (RES-E). This study assesses the near-term technical potential for biomass co-firing with coal in the existing coal-fired power plant infrastructure in the EU27 Member States. The total technical potential for RES-E from biomass co-firing amounts to approximately 50–90 TWh/yr, which requires a biomass supply of approximately 500–900 PJ/yr. The estimated co-firing potential in EU27 amounts to 20–35% of the estimated gap between current RES-E production and the RES-E target for 2010. However, for some member states the national co-firing potential is large enough to fill the national gap. The national biomass supply potential is considerably larger than the estimated biomass demand for co-firing for all member states. About 45% of the estimated biomass demand for co-firing comes from plants located close to the sea or near main navigable rivers and indicates the possibility for biomass import by sea transport. Thus, biomass co-firing has the potential to contribute substantially to the RES-E development in EU27.     

Critical analysis on hydrogen as an alternative to fossil fuels and biofuels for vehicles in Europe

In recent times, the global debate on the environment has been centered on CO₂ emissions. This gas is the major cause of the “greenhouse effect” and people are more concerned with the idea that the emissions of this gas should be minimized. As a result of this concern, the Kyoto Protocol was enacted and subscribed to by many countries, setting the maximum gas emissions for them.Fossil fuels are a major source of CO₂ emissions. For some years now The European Union has been seeking to promote some years now the use of biofuels as substitutes for diesel or petrol for transport purposes. As a result of this policy, in 2003 the European Union (EU) Directive 2003/30/EC [1] was developed with the aim of promoting the use of biofuels as a substitute for diesel or gasoline among European Union countries as well as to contribute to fulfilling the commitments acquired on climate change, security of supply in environmentally friendly conditions and the promotion of renewable energy sources.In order to achieve these goals, the directive forces all EU members to ensure that before December 31 of 2010 at least 5.75% of all gasoline and diesel fuels sold for transport purposes are biofuels. European Union countries have social and economic characteristics unique to themselves. The energy dependence on foreign sources, the features of the agricultural sector or the degree of industrialization varies greatly from one country to another. In this context, it is questionable whether the obligation imposed by this directive is actually achieving in its application uniform and/or identical goals in each of the countries involved and whether the actions of the various governments are also aligned with these goals. All these ideas were developed in a previous report (Sobrino and Monroy (2009) [2]).This report examines the possibility of using hydrogen as an alternative to fossil fuels and biofuels from a technical, economic and environmental point of view in the specific case of a European Union country: Spain.     

Assessment of forest biomass for use as energy. GIS-based analysis of geographical availability and locations of wood-fired power plants in Portugal

Following the European Union strategy concerning renewable energy (RE), Portugal established in their national policy programmes that the production of electrical energy from RE should reach 45% of the total supply by 2010. Since Portugal has large forest biomass resources, a significant part of this energy will be obtained from this source. In addition to the two existing electric power plants, with 22 MW of power capacity, 13 new power plants having a total of 86.4 MW capacity are in construction. Together these could generate a combination of electrical and thermal energy, known as combined heat and power (CHP) production. As these power plants will significantly increase the exploitation of forests resources, this article evaluates the potential quantities of available forest biomass residue for that purpose. In addition to examining the feasibility of producing both types of energy, we also examine the potential for producing only electric energy. Results show that if only electricity is generated some regions will need to have alternative fuel sources to fulfil the demand. However, if cogeneration is implemented the wood fuel resource will be sufficient to fulfill the required capacity demand.     

Biomass energy from wood chips: Diesel fuel dependence?

Most renewable energy sources depend to some extent on use of other, non-renewable sources. In this study we explore use of diesel fuel in producing and transporting woody biomass in the state of New Hampshire, USA. We use two methods to estimate the diesel fuel used in woody biomass production: 1) a calculation based on case studies of diesel consumption in different parts of the wood chip supply chain, and 2) to support extrapolating those results to a regional system, an econometric study of the variation of wood-chip prices with respect to diesel fuel prices. The econometric study relies on an assumption of fixed demand, then assesses variables impacting supply, with a focus on how the price of diesel fuel affects price of biomass supplied. The two methods yield similar results. The econometric study, representing overall regional practices, suggests that a $1.00 per liter increase in diesel fuel price is associated with a $5.59 per Mg increase in the price of wood chips. On an energy basis, the diesel fuel used directly in wood chip production and transportation appears to account for less than 2% of the potential energy in the wood chips. Thus, the dependence of woody biomass energy production on diesel fuel does not appear to be extreme.     

Impacts of policy means for increased use of forest-based bioenergy in Norway—A spatial partial equilibrium analysis

Like the European Union (EU), Norway has defined quite ambitious targets regarding increased use of bioenergy. However, the bioenergy market develops relatively slowly, and stronger policies seem necessary to reach the targets. This study analyses how different policy means, high on the agenda in the Norwegian energy debate, may affect the use of forest-based bioenergy in Norway. The means studied are (i) subsidies reducing investment costs of district heating installations, (ii) deposit grant for replacement of oil burners with burners based on bioenergy (iii) feed-in supporting energy production in district heating based on bioenergy. The study is based on a regionalised partial equilibrium model covering forestry, forest industries and the bioenergy sector. The advantage of this methodology is that it allows for assessments of the economic potential of bioenergy under different policy alternatives, taking into account the competition for raw materials from the forest industries, regional differences regarding heat demand and wood fibre supply, as well as important spatial aspects connected to inter-regional transport and trade of wood.

The results of the study give medium-term projections for bioenergy use in Norway under different bioenergy policy regimes. Some investments in bioburners in central heating systems and new district heating based on bioenergy are profitable at the current energy prices, but policy incentives in terms of grants, subsidies or feed-in systems make it possible to overcome inertia in investments decisions and provide substantial increase in the supply of bioenergy. The results show that the analysed policy means are effective at the current energy price levels and have a significant impact on bioenergy production. While some results are specific to Norway, other results and the methodology used are of more general value also to other European countries.
