Socio-Economic Comparative Analysis Of Front-Of-The-Meter And Behind-The-Meter Microgrids For Panamnik, Olivia C. Amann Mcshea
Socio-Economic Comparative Analysis Of Front-Of-The-Meter And Behind-The-Meter Microgrids For Panamnik, Olivia C. Amann Mcshea
Cal Poly Humboldt theses and projects
In Northern California, the Karuk Tribe is feeling the effects of climate change on inadequate energy infrastructures leading to unreliable power supply. Improving energy reliability in a way that also increases energy sovereignty is necessary. Renewable energy microgrids have emerged as a pathway forward.
Modeling ownership structures and cash flows for different microgrid configurations can support the Tribe’s implementation of a microgrid in Orleans, CA that maximizes community benefits. This thesis considers a front-of-the-meter (FTM) and behind-the-meter (BTM) configuration, both approximately 2 MW solar PV and 3 MW/12 MWh battery energy storage. Cash flows including capital costs, operations and maintenance …
Nā Pua Makani Wind Farm: The Shifting Winds Of Renewable Development In HawaiʻI, George Webster Ross Iv
Nā Pua Makani Wind Farm: The Shifting Winds Of Renewable Development In HawaiʻI, George Webster Ross Iv
Cal Poly Humboldt theses and projects
In 2015, Hawaiʻi set the most ambitious renewable energy portfolio goal in the nation by vowing to reach 100% renewable energy by 2045. Since then, many renewable energy development projects in Hawaiʻi have been met with strong community opposition, including the Nā Pua Makani wind farm (NPM) in Kahuku. The aim of this project is to analyze the process timeline of NPM to identify factors in the development process that contributed to organized protest, and to offer recommendations for improving the process. In order to get a full picture of the events throughout the Nā Pua Makani project’s timeline, my …
Process Optimization For An Integrated Reverse Osmosis—Pressure Retarded Osmosis Pilot-Scale System Operated On Humboldt Bay, Ca, Galen O'Toole
Process Optimization For An Integrated Reverse Osmosis—Pressure Retarded Osmosis Pilot-Scale System Operated On Humboldt Bay, Ca, Galen O'Toole
Cal Poly Humboldt theses and projects
Pressure retarded osmosis (PRO) is an emerging osmotic power technology that could mitigate the major challenges faced by seawater reverse osmosis desalination (RO): brine disposal and high energy consumption. The primary focus of this paper is process optimization for a linked seawater reverse osmosis (RO) and pressure retarded osmosis (PRO) water purification system. PRO generates power by using osmosis to “pump” water through a membrane from low pressure and low concentration to high pressure and high concentration (RO brine). This commercial-scale pilot effort explores process optimization for pressure retarded osmosis as an industrial process rather than theoretical or experimental process. …
The Politics Of Biomass Energy In California: How External Benefits Are Used To Support An Economically Marginal Sector, Dana L. Dysthe
The Politics Of Biomass Energy In California: How External Benefits Are Used To Support An Economically Marginal Sector, Dana L. Dysthe
Cal Poly Humboldt theses and projects
Since the 1990s, there has been a decline in biomass energy generation in California. In order to promote state governmental policies aiming to increase biomass energy generation in California, the sector has been linked to a series of external benefits that biomass energy purportedly brings. Through document analysis, semi-structured interviews, and participant observation, five distinct external benefits were identified that have been used to promote the biomass energy sector. These external benefits are: renewable energy generation, air quality improvements, promotion of forest restoration and fuel removal projects, disposal of wood waste from agricultural and forestry sectors, and rural economic development. …
Electrification Of Domestic Hot Water To Aid The Integration Of Renewable Energy In The California Grid, Alejandro Cervantes
Electrification Of Domestic Hot Water To Aid The Integration Of Renewable Energy In The California Grid, Alejandro Cervantes
Cal Poly Humboldt theses and projects
Water heating in residential buildings, also known as domestic hot water (DHW), is the third largest use of energy after appliances and space conditioning. About 90% of the residential buildings in the state use natural gas fueled water heaters, 6% use electricity, and a small percent use liquefied petroleum gas (LPG) or solar water heaters. The current energy use associated with residential water heating is small relative to the total amount of energy consumption in the residential building sector, but it is still a contributor of greenhouse gas (GHG) emissions. Improving hot water systems can be beneficial for bill customer …
Techno- Economic Feasibility Study Of Solar Water Pumping For Public Facilities In Nigeria, Anamika Singh
Techno- Economic Feasibility Study Of Solar Water Pumping For Public Facilities In Nigeria, Anamika Singh
Cal Poly Humboldt theses and projects
This thesis presents a techno-economic feasibility analysis of solar water pumping systems in public facilities located in rural parts of Nigeria. Three different public facilities namely, a primary health care center in Ibwa (PHC, Ibwa), a comprehensive health care center in Kwali (CHC, Kwali), and the LEA Primary School in Mapa (LEA School, Mapa), all located in Federal Capital Territory (FCT) of Nigeria, were analyzed. The facilities considered in the study have varying levels of water demand (micro, small, and medium), and they are used as cases to establish the techno-economic suitability of solar water pumping systems to deliver water …
Utility-Scale Solar Photovoltaic Hosting Potential Of Historic Mill Sites In Humboldt County, California, Michael Avcollie
Utility-Scale Solar Photovoltaic Hosting Potential Of Historic Mill Sites In Humboldt County, California, Michael Avcollie
Cal Poly Humboldt theses and projects
The adoption of Redwood Coast Energy Authority’s (RCEA’s) Community Choice Energy program in May of 2017 across Humboldt County has sparked interest in locally produced energy from solar photovoltaics (PV). RCEA has a goal of bringing 5 Megawatts (MW) of local, utility-scale, solar PV under contract by 2018 and 15 MW by 2023. Humboldt County’s former mill sites offer features that make them suitable for hosting PV development. This study performed an inventory and analysis of these sites to answer two questions: Can Humboldt County’s former mill sites provide the hosting capacity for15 MW of local, utility-scale solar PV? Which …
The Technical, Economic, And Environmental Feasibility Of Rice Straw Residue For Biomass Energy Production In India, Gaurav Kumar
The Technical, Economic, And Environmental Feasibility Of Rice Straw Residue For Biomass Energy Production In India, Gaurav Kumar
Cal Poly Humboldt theses and projects
This study assessed the feasibility of mobilizing rice straw (paddy residues) for small scale (250kW) bioenergy applications in India by establishing sustainable residue removal rates and cost of supply values for two production regions (Punjab and Haryana). A key objective was to refine the methodology for estimating costs for collection and transportation of rice straw harvesting for bioenergy use. The delivered cost of rice straw retrieved from one hectare of land and transported 10 km to the power plant has been estimated at INR 2.05 (USD 0.03) per kg. Various technological options have been explored for electricity generation from rice …
