Botanist, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Riverside, Calif. This session on the potential of Mediterraneantype ecosystems to supply biomass as a supplemental source of energy is a natural result of the present worldwide shortage of low-cost fuel. Some of these ecosystems are highly productive, partly because the summer droug...

Alternative energy sources, such as biomass CHP plants, have recently gained significantly in importance and action is due both on the large scale corporate level and on the small scale. Hence, making the scope and economic outline of such projects easily intelligible without losing relevant details seems a key factor to further promote the necessary developments. The model setup presented in t...

Biomass energy is the oldest energy source used by humans. Biomass has evolved as one of the most promising sources of fuel for the future1. This has spurred the growth of research and development efforts in both federal and private sectors. This impetus is motivated by several factors; dwindling fossil fuels and thus an increased need of energy security, environmental concerns and promotion of...

Hydrogen, a clean energy carrier with high energy capacity, is a very promising candidate as a primary energy source for the future. Photoelectrochemical (PEC) hydrogen production from renewable biomass derivatives and water is one of the most promising approaches to producing green chemical fuel. Compared to water splitting, hydrogen production from renewable biomass derivatives and water thro...

Hydrogen from Biomass as an energy carrier has generated increasing interest in recent years. There are several different technologies to convert solid or liquid Biomass into a gas mix consisting of mainly hydrogen and carbon dioxide. Up to 30% of the energy stored in the product gas would originate from the sun by using solar thermal applications to source the conversion while the equivalent o...

Introduction Rising concerns about long-term energy security, human health, global climate change, and a variety of other social and environmental concerns have combined to make developing renewable and sustainable alternatives to fossil fuels a critical national priority. Biomass, as a feedstock for renewable biofuels, bioproducts, and biopower, represents one such alternative, and one that ha...

This paper discusses the utilization of marine biomass as an energy resource in Japan. A marine biomass energy system in Japan was proposed consisting of seaweed cultivation (Laminaria japonica) at offshore marine farms, biogas production via methane fermentation of the seaweeds, and fuel cell power generation driven by the generated biogas. We estimated energy output, energy supply potential, ...

Environmental and sustainable economical concerns are generating a growing interest in biofuels predominantly produced from biomass. It would be ideal if an energy conversion device could directly extract energy from a sustainable energy resource such as biomass. Unfortunately, up to now, such a direct conversion device produces insufficient power to meet the demand of practical applications. T...

Natural energy reserves like petrol and diesel etc are depleting as such it is of paramount importance to find alternative fuels. Solar energy is traped as biomass in plants. Biomass provide an excellent reserve for traping solar energy on field. Complex enzymatic machinery comprising of hydrolytic reactions and consolidated bioprocessing is needed to make viable bioenergy mostly biofuels like ...
