Abstract:

This paper is a preliminary report on an assessment of technologies for hydrogen production from renewable resources, and an investigation of the problems and issues involved in assimilating this hydrogen into the overall energy economy. Hawaii was selected as the ideal laboratory for this purpose. The Hawaiian energy economy is reviewed to establish energy needs, and technologies available for conversion of indigenous resources (geothermal, wind, solar radiation, biomass, and ocean energy), into hydrogen or hydrogen-rich chemicals are assessed. Potential uses of hydrogen energy, for example, to provide transportation fuel or to generate electricity, and the problems of storage and distribution are examined. The assessment was about three-quarters finished at the time of this writing. The final results will be a plan for transition to increased uses of hydrogen, and identification of research and development needs to realize the potential benefits of hydrogen.
