Security aspects of future renewable energy systems–A short overview
Johansson, Bengt - In: Energy 61 (2013) C, pp. 598-605
Energy security is sometimes used to advocate renewable energy systems. Renewable energy systems can improve some aspects of security, but they will not automatically lead to the removal of all types of security problems and new problems will most certainly arise. This paper analyses energy...

Pre-treatment technologies, and their effect on international bioenergy supply chain logistics. Techno-economic evaluation of torrefaction, fast pyrolysis and pelletisation
Uslu, Ayla; Faaij, André P.C.; Bergman, P.C.A. - In: Energy 33 (2008) 8, pp. 1206-1223
The pre-treatment step has a significant influence on the performance of bioenergy chains, especially on logistics. Torrefaction, pelletisation and pyrolysis technologies can convert biomass at modest scales into dense energy carriers that ease transportation and handling.
