Marine algae have emerged as an alternative feedstock for the production of a number of renewable fuels, including biogas. In addition to energy potential, other characteristics make them attractive as an energy source, including their ability to absorb carbon dioxide (CO2), higher productivity rates than land-based crops and the lack of water use or land competition. For Ireland, biofuels from marine algae can play an important role by reducing imports of fossil fuels as well as providing the… Expand
Potential of seaweed as a feedstock for renewable gaseous fuel production in Ireland
An integrated model is suggested where seaweed can be co-digested with other feedstock for the sustainable production of gaseous fuel to facilitate EU renewable energy targets in transport. Expand

The present study tested four macroalgae species--harvested in Denmark--for their suitability of bioconversion to methane, finding that U. lactuca is often observed during 'green tides' in Europe and has a high cultivation potential at Nordic conditions, but the application of this algae at Danish centralized biogas plant is limited.

Anaerobic Digestion of Laminaria digitata: The Effect of Temperature on Biogas Production and Composition
A drop in pH in the mesophilic and thermophilic reactors was identified as an inhibitory factor during the first days of digestion, and psychrophilic reactors were better able to withstand the observed changes. Expand
