Summer seaweed, a new feedstock?

July 5, 2011 |

In the UK, researchers at Aberystwyth University claim seaweed may become a viable biofuel feedstock, especially if harvested in summer. Carbohydrate levels in kelp are at their highest in July, when harvesting would ensure optimal sugar release for biofuel production.Researchers collected monthly samples and used chemical analysis to assess the seasonal variability of kelp off the Welsh coast. Results indicated the best month for biofuel harvest was in July when the kelp contained the highest proportions of carbohydrate and the lowest metal content. Kelp can be converted to biofuels in different ways including fermentation or anaerobic digestion producing ethanol and methane or pyrolysis, which produces biodiesel.
