Two Plenary Sessions Highlights
Previews by
Dr. David Baxter
Former European Commission JRC, EUBCE Executive Committee Member
Bioenergy and Biobased Products
Plenary Session BP.2 Tuesday 6 June 13:45-14:45
Gasification is a key process for the conversion of a range of feedstocks to useful intermediate products that can subsequently be used to build a variety of products. One of the biggest challenges has been to scale up the gasification process to achieve commercial success. Enerkem has developed a bubbling fluidised bed system up to commercial demonstration scale in Edmonton that can use all sorts of agricultural and forestry residues as well as industrial and commercial wastes and mixed waste plastics. The presentation will cover all the main sub-processes in the conversion of raw feedstock into useful fuels and bio-based products, including methanol and ethanol at the demonstration facility.
In addition, an overview of target products and markets as well as the status of Enerkem’s most advanced projects in Canada and Europe will be given.
 The EU BRANCHES project has identified drivers and barriers for the integration of various technologies into farm and rural community bioeconomies, these technologies including biogas, hybrid energy solutions, biomass heating and CHP and advanced thermochemical conversion processes. Results from the research provide factors that may or may not have an impact on whether introduction of a bioeconomy solution could be successful. In this plenary presentation, the identified drivers and barriers affecting introduction of biomass conversion processes into rural communities will be given in terms of demographic, economic, political, ecological, socio-economic and technological factors.
Biomass Conversion to Bioenergy
Plenary Session CP.1 Wednesday 7 June 10:15-11:30
 This plenary session is dedicated to technologies for the conversion of biomass to bioenergy. Small-scale pellet boilers are installed in very many single home and multi-unit buildings across Europe. The attractiveness and success of the small-scale systems is achieved in large part by their ease of use, high thermal efficiencies and above all to their very low emissions that in the majority of cases are far below the EU Ecodesign Regulation. The plenary presentation will provide comparisons of existing generation with emerging best available technologies in the Austrian context.
Emerging technologies are aiming at emission-free pellet combustion as far as CO, gaseous organic compounds and particulate matter are concerned, and the technology approaches to achieve zero emissions will be discussed.
Gasification is again the topic of a plenary presentation and this time involves development of technology for a dual fluidised bed steam gasification system from pilot to demonstration scale, whereby the installation can receive biomass and waste feedstocks in a 1MW plant. The challenges of feedstock preparation, feeding to the gasification unit, gas cleaning and conditioning are discussed. In parallel, process flow simulation has been conducted to determine mass end energy balances, as well as raw gas quality, and to reduce experimental time and risks involved in scaling up to the 1 MW system.
The final presentation in the session addresses the large potential for expansion of biogas production in Europe up to 2030 and how this might be achieved. The presenter will describe how it should be possible to expand from the current 20 million tonnes of oil equivalent (mtoe) biogas production to 100 mtoe in 2030 using a much higher proportion of manure and animal slurries than now, as well as lignocellulosic biomass, which in some cases will involve additional feedstock pretreatments prior to the biogas process. One of the big drivers for the scale-up of biogas production is the storage potential for biogas, or biomethane, the refined form of biogas, and the integrated use of the stored gas to balance electricity grids that are increasingly dominated by variable inputs from wind and solar sources. The added benefit of the utilisation of CO2, derived from biogas upgrading to biomethane, in the production of for example e-fuels will also be discussed.
