Collana: BT - 17 - Feb 03 - Le biomasse nel panorama energetico italiano
Note:
Globally, organic Biomass and combustible fuels from municipal waste are available in
enormous quantities. The Finnish Power Company Wärtsilä, for its part, has identified a particular
sector within bio-energy to grow its power business. Through the acquisition of Sermet OY, Wärtsilä
is already a leading supplier of boilers for bio-fuels in the Nordic countries.
There is a strong political and social will world-wide to increase the use of renewable energy
in power and heat generation. The combined output of Biomass fuelled power plants currently under
construction in Europe totals approximately 1,000 MW; in North America this trend is also
developing, especially in Canada where half the world’s production of wood fuel may be found.
Due to extensive fuel supply management issues, Biomass fuelled power plants are typically smaller
in power output, and they favour distributed energy production. These small size biopower units
have been rarely feasible without governmental subsidies due to the high investment costs. Now,
with the trends of increasingly volatile fossil fuel prices and an increased awareness of
environmental issues, the means are developing to support low fuel price, CO2-free energy
technologies.
As a global endeavour, the ultimate goal in making a Biomass plant feasible in small-scale
units is to reduce the investment cost to the level where subsidies are no longer necessary. That
challenge has been taken seriously within Wärtsilä. By standardising and serialising the processes,
boiler sizing, and fuel input types, the price of small-scale biopower can be reduced to commercial
levels without the aid of subsidies.
