Offi cially, the use of biomass for energy meets only 10-13% of the total global energy demand of
140 000 TWh per year. Still, thirty years ago the offi cial fi gure was zero, as only traded biomass Dahlquist
was included. While the actual production of biomass is in the range of 270 000 TWh per year,
most of this is not used for energy purposes, and mostly it is not used very effi ciently. Therefore,
there is a need for new methods for converting biomass into refi ned products like chemicals,
fuels, wood and paper products, heat, cooling and electric power. Obviously, some biomass
is also used as food – our primary life necessity. The different types of conversion methods
covered in this volume are biogas production, bio-ethanol production, torrefaction, pyrolysis,
BT
high temperature gasifi cation and combustion. ioec
This book covers the suitability of different methods for conversion of different types of biomass. mh

Different versions of the conversion methods are presented – both existing methods and those aso
being developed for the future. System optimization using modeling methods and simulation are s log
analyzed to determine advantages and disadvantages of different solutions. toie

SUSTAINABLE ENERGY DEVELOPMENTS – VOLUME 4 ISSN 2164-0645 yin
g
The book series addresses novel techniques and measures related to sustainable energy
developments with an interdisciplinary focus that cuts across all fi elds of science, engineering
and technology linking renewable energy and other sustainable materials with human society. It
addresses renewable energy sources and sustainable policy options, including energy effi ciency
and energy conservation to provide long-term solutions for key-problems of industrialized,
developing and transition countries by fostering clean and domestically available energy and,
concurrently, decreasing dependence on fossil fuel imports and reducing greenhouse gas
emissions. Possible applications will be addressed not only from a technical point of view, but
also from economic, fi nancial, social, political, legislative and regulatory viewpoints. The book
series aims to become a state-of-the-art source for a large group of readers comprising different
stakeholders and professionals, including government and non-governmental organizations and
institutions, international funding agencies, universities, public health and energy institutions,
and other relevant institutions.
