Description

The current fossil fuel reserves are not sufficient to meet the increasing demand and very soon will become exhausted. Pollution, global warming, and inflated oil prices have led the quest for renewable energy sources. Algal biofuels represent a potential source of renewable energy. Algae, as the third generation feedstock, are suitable for biodiesel and bioethanol production due to their quick growth, excellent biomass yield, and high lipid and carbohydrate contents. With their huge potential, algae are expected to surpass the first and second generation feedstocks. Only a few thousand algal species have been investigated as possible biofuel sources, and none of them was ideal. This review summarizes the current status of algal biofuels, important steps of algal biofuel production, and the major commercial production challenges.

Translated Description (Arabic)

لا تكفي احتياطيات الوقود الأحفوري الحالية لتلبية الطلب المتزايد وستنفد قريبًا جدًا. أدى التلوث والاحترار العالمي وتضخم أسعار النفط إلى البحث عن مصادر الطاقة المتجددة. يمثل الوقود الحيوي للطحالب مصدرًا محتملًا للطاقة المتجددة. الطحالب، كمادة وسيطة من الجيل الثالث، مناسبة لإنتاج الديزل الحيوي والإيثانول الحيوي بسبب نموها السريع، وإنتاجها الممتاز من الكتلة الحيوية، ومحتوياتها العالية من الدهون والكربوهيدرات. مع إمكاناتها الهائلة، من المتوقع أن تتجاوز الطحالب الجيل الأول والثاني من المواد الأولية. لم يتم التحقيق إلا في بضعة آلاف من أنواع الطحالب كمصادر محتملة للوقود الحيوي، ولم يكن أي منها مثاليًا. تلخص هذه المراجعة الوضع الحالي للوقود الحيوي للطحالب، والخطوات المهمة لإنتاج الوقود الحيوي للطحالب، وتحديات الإنتاج التجاري الرئيسية.

Translated Description (French)

Les réserves actuelles de combustibles fossiles ne sont pas suffisantes pour répondre à la demande croissante et vont très bientôt s'épuiser. La pollution, le réchauffement climatique et l'inflation des prix du pétrole ont conduit à la recherche de sources d'énergie renouvelables. Les biocarburants algaux représentent une source potentielle d'énergie renouvelable. Les algues, en tant que matière première de troisième génération, conviennent à la production de biodiesel et de bioéthanol en raison de leur croissance rapide, de leur excellent rendement en biomasse et de leur teneur élevée en lipides et en glucides. Avec leur énorme potentiel, les algues devraient dépasser les matières premières de première et de deuxième génération. Seules quelques milliers d'espèces d'algues ont été étudiées comme sources possibles de biocarburant, et aucune d'entre elles n'était idéale. Cette revue résume l'état actuel des biocarburants à base d'algues, les étapes importantes de la production de biocarburants à base d'algues et les principaux défis de la production commerciale.

Translated Description (Spanish)

Las reservas actuales de combustibles fósiles no son suficientes para satisfacer la creciente demanda y muy pronto se agotarán. La contaminación, el calentamiento global y los precios inflados del petróleo han liderado la búsqueda de fuentes de energía renovables. Los biocombustibles de algas representan una fuente potencial de energía renovable. Las algas, como materia prima de tercera generación, son adecuadas para la producción de biodiesel y bioetanol debido a su rápido crecimiento, excelente rendimiento de biomasa y alto contenido de lípidos y carbohidratos. Con su enorme potencial, se espera que las algas superen a las materias primas de primera y segunda generación. Solo se han investigado unos pocos miles de especies de algas como posibles fuentes de biocombustibles, y ninguna de ellas era ideal. Esta revisión resume el estado actual de los biocombustibles de algas, los pasos importantes de la producción de biocombustibles de algas y los principales desafíos de la producción comercial.
