Abstract:
This study explores the potential of Icelandic seaweed as a renewable biofuel source, focusing on the optimization of drying and pelletizing processes to improve its viability. Freshly harvested seaweed contains over 70% moisture, necessitating energy-intensive drying prior to pelletizing. This study has three primary objectives: (1) evaluating the energy content of various Icelandic seaweed species to determine their suitability for biofuel and as nutritional supplements; (2) reducing energy demands during the drying process through optimized intermittent drying techniques, addressing a critical cost driver in biomass processing; and (3) developing high-density, durable seaweed pellets suitable for, including gasification for sustainable electricity production, as a renewable carbon source in industrial processes, and as consumer heating fuel. The outcomes aim to establish an efficient, economically viable pathway for converting seaweed into a competitive biofuel, contributing to advancements in biomass processing technologies and supporting Iceland’s renewable energy transition.
