New Report – Examples of Positive Bioenergy and Water Relationships
Bioenergy is, and will continue to be, a substantial part of the global renewable energy supply in a low carbon economy. Sustainable production and use of bioenergy offers tremendous opportunities for creating positive socio-economic and environmental impacts. The water-energy nexus has been identified as one of those opportunities. Presenting innovative examples is a means of showcasing how bioenergy systems – in both the feedstock production and conversion phases – can generate positive impacts on water and energy. To realise such a showcase, the Global Bioenergy Partnership (GBEP) and the International Energy Agency (IEA) Bioenergy Technology Cooperation Programme (IEA Bioenergy) have joined forces to collect information, analyse it and present the results.
This new report, which is the product of the GBEP / IEA Bioenergy collaboration includes examples that illustrate an encouraging variety both in terms of bioenergy systems and geographical distribution, and shows how solutions can be found that produce bioenergy while contributing positively to the state of water. These experiences are also meant to serve as sources of inspiration that other bioenergy producers can use to enhance the sustainability of their own activities.
New Report – The status of large scale biomass firing
This report provides an overview of the current status of biomass cofiring. This report shows that the firing and co-firing of biomass as a replacement for coal in large pulverised coal boilers can be a very attractive option for the utilisation of biomass materials for power production, and for the delivery of renewable energy.
The case studies and country reports show that through the years, a great experience has been gained with biomass cofiring in various types of power plants and with various types of biomass fuels. These projects show that the technical risk areas have been managed successfully and that the plant availability and efficiency levels after conversion have been acceptable.
Technical Report – Exploring the viability of small scale anaerobic digesters in livestock farming
This report explores the viability of small scale anaerobic digestion for livestock farming where there is a need to deal with animal manure and slurry in a manner that minimises the emission of greenhouse gases. Dairy farming for example is dominated by small herds of animals, the slurry from which must be managed efficiently for the farm and to maintain high standards of health in a cost effective manner. The methodology described in the Report is designed to enable prospective users to substitute their own data appropriate to their respective situations at any point in time.
The report is aimed at energy policy and decision makers as well as WWTP operators and was produced by IEA Bioenergy Task 37, an expert working group that addresses challenges related to the economic and environmental sustainability of biogas production and utilisation.
New Technical Report – The contribution of Danish forestry to increase wood production and offset climate change 2010-2100
This IEA Bioenergy Task 43 technical report shows that it is possible to increase the productivity of the Danish forests considerably and provide a significant contribution to Danish energy targets of achieving a 100 % supply of energy from sustainable sources in 2050 as well as to the reduction of Danish CO2 emissions. The potential for provision of these services from Danish forests is probably bigger than generally acknowledged given the fact that Denmark is a low forest cover country.
