Hawaii integrated energy assessment : volume I overview

The Hawaii Integrated Energy Assessment (HIEA) is designed to aid decision makers in Hawaii as they plan the transition from nearly total dependence upon oil to a mix of renewable, indigenous energy resources during the next 25 years. Recognition that an integrated assessment of Hawaii's energy future would be useful during this transition grew out of discussions between the State of Hawaii Department of Planning and Economic Development (DPED) and the San Francisco Operations Office of the United States Department of Energy (DOE). Subsequently commissioned by DOE with funding from its Office of Solar Strategy, Analysis and Integration, and the Office of Resource Applications, with further assistance from the State of Hawaii, this study was undertaken as a collaborative effort by the Lawrence Berkeley Laboratory and DPED. This assessment is intended to be as realistic as possible in its analysis of the prospects for commercial evolution of the energy technologies that are appropriate for Hawaii and in its examination of the many-faceted implications of developing those technologies. As a result, the HIEA conclusions may be more restrained than those with a more optimistic range of opinions might expect. This report offers a series of views of possible future events. Like any other look into the future, it becomes more tenuous the farther it reaches. It is not intended as a definitive evaluation of the alternate energy technologies it considers nor as a precise forecast of things to come. The basic analytical models used in the assessment, however, will continue to be useful tools if updated data are introduced over the years. The transition to indigenous energy resources will call for a sequence of aggressive, informed decisions as the real future unfolds. It is hoped that the information presented in the seven volumes of the HIEA report will provide a sound basis for these decisions. The many experts from diverse fields and institutions who participated in these studies are acknowledged in the appropriate volumes. We commemorate here the late Dr. Eugene M. Grabbe, former Manager of the DPED's State Center for Science Policy and Technology Assessment, for his key role in initiating the project and guiding its earliest work.This work was supported by the U.S. Department of Energy's Assistant Secretary for Conservation and Solar Energy, Office of Solar Strategy, Analysis and Integration, and the Assistant Secretary for Resource Applications, under Contract No. W-740S-ENG-48 with the University of California and under Grant No. EP-78-G-03-2100 with the Department of Planning and Economic Development, State of Hawaii

Pahoa geothermal industrial park. Engineering and economic analysis for direct applications of geothermal energy in an industrial park at Pahoa, Hawaii

This engineering and economic study evaluated the potential for developing a geothermal industrial park in the Puna District near Pahoa on the Island of Hawaii. Direct heat industrial applications were analyzed from a marketing, engineering, economic, environmental, and sociological standpoint to determine the most viable industries for the park. An extensive literature search produced 31 existing processes currently using geothermal heat. An additional list was compiled indicating industrial processes that require heat that could be provided by geothermal energy. From this information, 17 possible processes were selected for consideration. Careful scrutiny and analysis of these 17 processes revealed three that justified detailed economic workups. The three processes chosen for detailed analysis were: an ethanol plant using bagasse and wood as feedstock; a cattle feed mill using sugar cane leaf trash as feedstock; and a papaya processing facility providing both fresh and processed fruit. In addition, a research facility to assess and develop other processes was treated as a concept. Consideration was given to the impediments to development, the engineering process requirements and the governmental support for each process. The study describes the geothermal well site chosen, the pipeline to transmit the hydrothermal fluid, and the infrastructure required for the industrial park. A conceptual development plan for the ethanol plant, the feedmill and the papaya processing facility was prepared. The study concluded that a direct heat industrial park in Pahoa, Hawaii, involves considerable risks
