随着不可再生的化石燃料的迅速消耗,人们开始生产可再生的生物质能源,例如从玉米、甘蔗等作物里面提取燃料,但这样做会消耗很多粮食。所以,人们将目光投向浩瀚大海中的生物质——海藻。大型海藻(如褐藻)中含有大量天然多糖(藻酸盐),提取转化后,就可以制成乙醇等燃料。2012年1月,美国加州生物建筑实验室公司(Bio Architechture With the rapid depletion of non-renewable fossil fuels, people start to produce renewable biomass energy sources such as fuels from crops such as corn and sugar cane, but doing so consumes too much food. Therefore, people look to the vast sea of ​​biomass - seaweed. Large seaweed (such as brown algae) contains a lot of natural polysaccharides (alginate), extraction and conversion, you can make ethanol and other fuels.
