Growing Fuel

Why-not-algae-fuel-part-1

EN Ten acres of land between chimneys and silos, pierced by hundreds of clear plastic tubes 8 feet high, filled with single-celled algae diatoms that grow through photosynthesis a million times faster than what happens in nature: this is how Porto Marghera may appear in a few years. The proposed power plant would be able to produce about 40 megawatts, the equivalent of half the energy needed for the inhabitants of the historic city of Venice. The project was drafted by the new eNave company owned at 50% by the port authority.

The energy from algae could be the renewable source of the future: clean, CO2 devouring and with great energy efficiency. Recently the commercial development of large-scale algae biodiesel has proven to be renewable source with great competitive advantages. The process for the production of biodiesel from algae does not consume other biomass (sugar) to produce biomass. In addition, it requires large areas without having to subtract land to agriculture. It is in fact desirable to build this plants in the proximity of industrial plants with large CO2 emissions, since the algae need it to sustain their growth process.

IT Dieci ettari di terreno tra le ciminiere e i silos, trafitti da centinaia di tubi di plastica trasparente alti 8 metri, ripieni di alghe diatomee monocellulari che grazie alla fotosintesi crescono un milione di volte in più di quanto accade in natura: così potrebbe apparire Porto Marghera tra qualche anno. L’impianto progettato sarebbe in grado di produrre circa 40 megawatt, vale a dire l’equivalente della metà dell’energia necessaria agli abitanti del centro storico di Venezia. A firmare il progetto la nuova eNave partecipata al 50% dall’autorità portuale.

L’energia dalle alghe potrebbe essere la fonte rinnovabile del futuro: pulita, “divoratrice” di CO2 e con grande resa energetica. Recentemente si guarda allo sviluppo commerciale su larga scala di biodiesel da alghe come una fonte rinnovabile dai grandi vantaggi competitivi. Il processo per la produzione di biodiesel a partire dalle alghe non consuma altre biomasse (zucchero) per produrre biomassa. Inoltre, necessita di ampie aree ma senza doverle sottrarre all’agricoltura è addirittura auspicabile la vicinanza a impianti industriali con grosse emissioni di CO2, di cui le alghe si nutrono per sostenere il loro processo di crescita.
