生質能相較於傳統化石能源，具有避免大氣中二氧化碳濃度上升以及含硫量低等優點。與其他再生能源相較，生質能生產技術成熟，應用方式廣泛，與現有能源應用的軟硬體設施相容性高，具有取代交通運輸用燃料的能力。
其中，丁醇的用途廣，除了可作為燃料添加劑之外，還是塑料工業中重要的原料化學品；以往每年10〜12十億磅的丁醇由石化原料製成，且需求可能尚在增加中。使用廉價的非食物含碳基質來發展生質丁醇，以達到經濟可行性，是很重要的。
四面環海的台灣，占地利優勢，應嘗試發展以藻類作為生物質；藻類是光自營的生物，生產方法簡便，且以「生物精煉」的概念來看，不僅可提煉藻油、或以藻類多糖醱酵產生燃料，也能夠得到豐富的Omega-3脂肪酸以及DHA等成份，而這些成份皆可作為珍貴食品添加物。如果成功發展生質能源，將成為可持續生產的優越生質燃料。
最後，生質能源的技術可以有延續性，即使使用不同原料或產生不同目標產物，技術或菌秼可能可以相互流用，提升技術研發的價值，如丁醇生產獲得的知識可用於生產其他高鏈醇，例如戊醇。

關鍵字：生質能源、生質丁醇、藻類生質能、生物精煉

Biomass energy compared to traditional fossil fuels, can reduce the concentration of carbon dioxide in the atmosphere, and its sulfur content is low. Compared with other renewable energy sources, biomass energy production technology is mature and widely used, and is highly compatible with existing energy facilities such as hardware and software, has the ability to replace transport fuels.
Wherein biobutaonl could be used as a fuel additive, and plastic important industrial raw chemical also. Annually in the past 10 to 12 billions of pounds of biobutanol is made from the petrochemical raw materials and demand may still increase. Development of biobutanol, non-food use of inexpensive carbon substrates to achieve economic viability is important.
Taiwan surrounded by sea should try to develop algae as biomass. Since algae is light self-creatures, with "bio-refinery" concept point of view, not only can extract algae oil, polysaccharide fermentation to produce fuels, but also to get rich DHA Omega-3 fatty acids and other ingredients, and these ingredients can be as precious food additives. If development of biomass energy is success, it will become the sustainable production of biofuels.
Finally, biomass energy technologies might have things in common, even using different biomass or producing different target products, technology or bacteria stain may be able to flow with each other, which can enhance the value of technology research and development. For example, knowledge of butanol production can be used to produce other high chain alcohols such as amyl alcohol.

Key words: Biofuel, Biobutanol, Algal Biomass, Biorefinery
