Biomass Production by Freshwater and Marine Macrophytes


Biomass plantations for energy production in coastal and oceanic settings have several inherent attractions. Water requirements for aquatic plants may pose no serious limitations. Algal tissues do not contain high proportions of refractory materials such as lignin and cellulose (which might complicate processes for conversion to certain fuels). Many algal species show little or no seasonal changes in potential for growth and presumably can be maintained indefinitely. Photosynthetic conversion efficiencies are good. Space is abundant in the oceanic environment and environmental energy in waves and currents might be utilized for tasks such as obtaining and dispersing plant nutrients.
