Could kelp be the next biofuel?
IBERS - the Institute of Biological, Environmental & Rural Sciences at Aberystwyth University has revealed findings of research held into the viability of kelp as a biofuel for the future. It was also discussed how the suitability of its composition varies on a seasonal basis as harvesting the kelp in July when carbohydrate levels are at their highest would ensure optimal sugar release for biofuel production. “The storage carbohydrate and soluble sugars get converted into ethanol in the fermentation process, so we need as much as possible,” explains Dr Jessica Adams, a lead researcher at Aberystwyth University. “Metals can inhibit the yeast too so we also want these to be as low as possible”. Collecting monthly samples of kelp from the Welsh coast, researchers used chemical analysis to assess the seasonal variability. Their results, which were presented at the Society for Experimental Biology Annual Conference in Glasgow, showed that the best month for biofuel harvest was in July w...
