Production of energy vectors from microalgae may provide an effective path toward mitigation of green-house gas accumulation and fossil-to-renewable energy shift.

Abstract
Production of energy vectors from microalgae may provide an effective path toward mitigation of green-house gas accumulation and fossil-to-renewable energy shift. Fostering exploitation of microalgae as feedstocks for energy vectors meets the basic constraints of renewable energy policy. Reduction of green-house gas emissions may be pursued with a balanced competition of energy feedstocks with otherwise food-oriented agricultural commodities. Autotrophic microalgae are able to capture CO2 and light and to photosynthetically produce energy vectors. The photosynthetic efficiency is ten times larger than terrestrial plants. Simple mass/energy balances indicate that the amount of CO2 present/released in the atmosphere and the incident solar flux exceed by far those needed to meet the current worldwide energy demand. A review of processes to produce energy vectors is presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
