AbstractAbstract
[en] A hierarchical control strategy is formulated for coordination of hydro and biomass electric energy cogeneration with two hierarchical coupled problems. The first problem under consideration concerns long-term strategies for hydroelectric system and forest development, so as to obtain a target biomass output yearly. The second problem schedules hydroelectric and biomass-powered plants to meet loads over a mid-term horizon, such that the use of either hydro or biomass resources are minimized. An optimal control and optimization methods are proposed for tile coordination of hydro and biomass electric energy cogeneration

AbstractAbstract
[en] An overview is given of bottlenecks and solutions with regard to Dutch sustainable energy supply policy, focusing on biomass experiments
[nl]
Het Ministerie van Economische Zaken geeft invulling aan de transitie naar een duurzame energievoorziening. Biomassa is hierin een van de deelprojecten. Op basis van de lange termijn visie die in het eerste traject is uitgewerkt, zijn door de marktpartijen transitiepaden en experimenten vorm gegeven. Gezien de vernieuwing die in de biomassatransitie wordt nagestreefd, is het goed mogelijk dat deze paden en experimenten tegen bestaande beleidskaders oplopen. Dit omdat deze mogelijk nog niet voldoende zijn ingesteld op het vernieuwende karakter van de transitiepaden. Deze rapportage geeft een beknopt overzicht van de mogelijke knelpunten en oplossingsrichtingen in relatie tot overheidsbeleid. Ze is de weerslag van interviews met de trekkers van de transitiepaden, enkele vertegenwoordigers van de NGO's en enkele andere relevante experts aan wie gevraagd is welke knelpunten zij voorzien voor de komende 5-10 jaarOriginal Title

AbstractAbstract
[en] Biomass has been used as a fuel source for centuries, but mainly in the production of low grade heat. However, it can be used as a fuel for power generation, a particular advantage for remote rural areas rich in agricultural wastes but with weak or no grid connection as it avoids the need for importing fossil fuels. Likewise factories producing suitable such wastes, i.e. sugar mills and paper mills, have the possibility of reducing their energy bills by replacing the fossil fuels used to produce process steam and imported electricity with an on-site co-generation scheme

AbstractAbstract
[en] Dangogo and Fernando suggested that a laboratory qualitative assessment of the manurial quality of digester slurry can be achieved by analyzing nitrogen (N) phosphorus (P) and potassium (K) content. Analyzing data from our study indicate an approximate range of nutrient contents of BSG digester manure to be within the following ranges, 0.50 - 0.61%, phosphorus, 0.55- 0.58% potassium and 3.14 - 3.48'% nitrogen for dried sludge. (Figures are not corrected for loss of nitrogen and other nutrients on drying). From the field study, it is apparent from the percentage biological yield that the digester dry manure is a better fertilizer than humus

AbstractAbstract
[en] This is the opening chapter of the book ''Bio energy - Environment, technique and market''. The chapter opens by discussing bio energy in a historical perspective, then describes energy and energy use in a global perspective, and ends with sections on energy policy and environmental policy. It includes sections on heat as an alternative to hydroelectric energy, international emission commitments, the Kyoto Protocol and carbon dioxide emission, political instruments, and bio energy in developing countries. The book emphasises Norwegian, or Scandinavian, conditions

AbstractAbstract
[en] The possibilities for using biomass as a commercial source of gaseous fuel and energy in the world and individual countries are considered. The technologies for obtaining solid, liquid and gaseous fuels from various types of biomass - from photosynthetic up to organic wastes - are developing in two directions: the thermochemical and biotechnological ones. Industrial application of biomass in industrial countries includes: production of wood charcoal, electricity, thermal energy in the apartment houses, cottages, villas and country-houses, low-scale industrial application, decentralized energy supply. The biomass in developing countries is the main source of energy for multiple craftsmen and small-scale works

Рассматриваются возможности использования биомассы в качестве коммерческого источника газообразного топлива и энергии в мире и в отдельных странах. Технологии получения твердых, жидких и газообразных топлив из различных видов биомассы - от фотосинтетической до органических отходов - развиваются по двум направлениям: термохимическому и биотехнологическому. Промышленное применение биомассы в индустриальных странах включает в себя: получение древесного угля, электричества, тепловой энергии в многоквартирных домах, коттеджах, виллах и дачах, малое промышленное применение, децентрализованное получение энергии. В развивающихся странах биомасса является главным источником энергии для многих ремесленников и малых производствOriginal Title
