Seaweed biomethane delivers 60% carbon savings vs fossil fuel.
A study finds that seaweed biomethane can deliver over 60% carbon savings as compared to fossil fuel. The focus of the study is to assess the sustainability of seaweed biomethane, with seaweed sourced from an integrated seaweed and salmon farm in Ireland. In the past, full comprehensive LCA studies of seaweed biofuel were limited, with previous studies focusing mainly on microalgal biofuels. According to the study, the baseline scenario shows high emissions in all impact categories with an optimal seaweed biomethane system being able to achieve 70% savings in GHG emissions as compared to gasoline with high yields per hectare.
