The city of Venice hopes to get at least 50 per cent of electricity from renewable sources by the year 2011. It plans to use algae to generate electricity.
Venice, known as the City of Bridges, plans to end its reliance on fossil fuels in the near future by primarily using biofuels.
As a first step the city officials have invested €200 million ($264 million) for a biofuels plant. They will use two types of algae,
Sargassum muticum and
Undaria pinnafitida. They will cultivate them in laboratories, which will then be used to generate electricity in a new 40 MW power plant. This plant will provide up to 50 per cent of the city’s electricity needs.
The algae-to-fuel conversion process works as
follows:
The algae will be cultivated in laboratories and put in plastic cylinders where water, carbon dioxide, and sunshine can trigger photosynthesis. The resulting biomass will be treated further to produce a fuel to turn turbines. The carbon dioxide produced in the process will be fed back to the algae, resulting in zero emissions from the plant.
Paolo Costa, President of the seaport of Venice Authority told
Ecoworldly.com:
Venice could represent the beginning of a global revolution of energy and renewable resources. Our goals are to achieve the energetic self-sufficiency for the seaport and to reduce CO2 emissions, including those one produced by the docked ships.
