Optimal Geothermal Heat Extraction Using Co2, Iti Patel, Jeffrey Bielicki

CO2 Summit II: Technologies and Opportunities

Carbon dioxide (CO₂) capture and storage (CCS) systems alleviate global climate change through the subsurface storage of CO₂ emission. This CCS technology can be costly, but CO₂ Capture, Utilization, and Storage (CCUS) approaches can decrease the cost of CCS, because sequestered CO₂ is used to produce an economically viable commodity. In one CCUS application, CO₂ that is sequestered in sedimentary basins during the CCS process can be used to extract geothermal heat that can then be used to generate a profit^1,2. These CO₂-geothermal systems rely on the temperature of …

Ccs Cost Trends And Outlook, Edward Rubin

CO2 Summit II: Technologies and Opportunities

Based on a review and analysis of recent cost studies, this paper assesses the current costs of CO2 capture and storage (CCS) for new fossil fuel power plants and compares them to costs reported a decade ago in the IPCC Special Report on Carbon dioxide Capture and Storage (SRCCS). The major CCS options include post-combustion CO2 capture at supercritical pulverized coal (SCPC) and natural gas combined cycle (NGCC) power plants, pre-combustion capture at coal-based integrated gasification combined cycle (IGCC) power plants, and SCPC plants employing oxy-combustion for CO2 capture. Transport and storage options include pipeline and geological storage, including utilization …

Cryogenic Carbon Capture, Larry Baxter, Andrew Baxter, Chris Bence, David Frankman, Chris Hoeger, Aaron Sayre, Kyler Stitt, Skyler Chamberlain

CO2 Summit II: Technologies and Opportunities

Cryogenic Carbon Capture™ (CCC) removes CO2 from flue gas in a bolt on retrofittable, cost-effective, and energy-efficient process. The process also provides grid-level energy storage capable of storing and releasing energy at hundreds of megawatt rates at high efficiency and minimal cost beyond the costs of the carbon capture technology. The energy storage can level daily load fluctuations and responds to intermittent power sources on time scales comparable to solar and wind farms. The technology cools flue gases to their condensation (desublimation) point forming solid CO2, separates the solids from the residual gases, pressurizes the solids, and reheats both streams …

Puddl: Gamifying Water Conservation, Quince Assenberg, Jack Chen, Denny Glenn, Jessica Lam

PSU High School Innovation Challenge

As the global population surges, the demand for fresh water will only increase. With no technological breakthrough on the horizon, it is more important than ever to conserve water and not waste this precious resource. Water conservation is a serious issue, and will only become more severe as global warming worsens. As the global temperature increases, and rainfall becomes more sporadic, it will be important for communities to find new ways to save water. This push has already been made in certain areas in the united states, California, where they were forced to reduce their water consumption by 25%.

In America today, over 75% of the nation’s water is used in the irrigation of agriculture. The main users -- and abusers -- of water in the United States are farmers. In addition, many areas in the U.S. are facing drought conditions, especially in western states. Also, while the drought conditions in California are receding, water shortage as an issue demands a long term solution.

Isolated Water Circulation And Filtration System, Adrik Gurganus, Mellonie Mwawai, Wysteria Cedillo-Nielsen, Morgan Rekart, Zander Hoffman

PSU High School Innovation Challenge

One big issue we are addressing is the large amount greywater produced by average households around the country. Still, the main problem is that, in areas affected by drought such as California, people have little available clean water, and this system will greatly benefit these people directly. The Isolated water system uses a filtration combined of organic materials, soaps, dirt, foods and sink to filter out the grey used water. Since the water system is not connected with the local water system if there were a natural disaster the owner would have free access to a water source while the …

Residential Greywater Recycling System, Sophia Bui, Clare Clark, Anthony Hoang, Kim Le, Skyler Mishler, Janette Soler, Teresa Tran

PSU High School Innovation Challenge

In a typical household, a majority of the fresh water is utilized by the shower, bathroom sinks and laundry. Water exiting from these fixtures is considered greywater. This is wasteful because the greywater is being combined with blackwater making it unusable. If greywater could be separated and captured, it can be reused for other purposes. We came to the conclusion that greywater is able to be recycled and reused for flushing excreta.

Many cities across the country have experienced extreme water problems. The City of Portland has issued several water boiling advisories due to E. coli contamination. Additionally, there has been incidents of serious contaminants like lead leaching in water systems (Flint, Michigan). The Portland Water Bureau does not use a water treatment plant due to the quality of our water sources; a chlorination plant is used to chlorinate the water from the Bull Run Watershed (our main water source). Not having a water treatment plant makes Oregon more prone to a prolonged absence of potable water should the supply be contaminated. …

The goal of this research is to identify how flow on the Bear River in Cache Valley has changed over the last three years and how flow changes seasonally. Identifying flows is important to manage water resources along the Bear River. We collected and processed water pressure data every 30 minutes using HOBO transducers at two sites in Cache Valley (Morton, just downstream of highway 142, and Confluence which is located at the confluence of the Bear and Cub Rivers) south of the Idaho‐Utah border in 2015. We also measured flow and water stage up to three times per year …

Micro- And Nanoparticulates For Dna Vaccine Delivery, Eric Farris, Deborah M. Brown, Amanda Ramer-Tait, Angela K. Pannier

Department of Agricultural and Biological Systems Engineering: Faculty Publications

DNA vaccination has emerged as a promising alternative to traditional protein-based vaccines for the induction of protective immune responses. DNA vaccines offer several advantages over traditional vaccines, including increased stability, rapid and inexpensive production, and flexibility to produce vaccines for a wide variety of infectious diseases. However, the immunogenicity of DNA vaccines delivered as naked plasmid DNA is often weak due to degradation of the DNA by nucleases and inefficient delivery to immune cells. Therefore, biomaterial-based delivery systems based on micro- and nanoparticles that encapsulate plasmid DNA represent the most promising strategy for DNA vaccine delivery. Microparticulate delivery systems allow …

Procedural Treatment Options To Address Intermittent Pentachlorophenol Effluent Exceedances At A Former Wood-Treatment Site In Butte, Montana, Travis Dunkle

Graduate Theses & Non-Theses

The Montana Pole and Treating Plant in Butte, Montana treated wood with preservatives, mainly pentachlorophenol (PCP), which had been dissolved in a carrier fluid. Accidents and careless handling spilled large quantities of the fluid on the site, contaminating the vadose zone and groundwater. This site has been undergoing remediation since it was added to the CERCLA National Priorities List in 1987. Pentachlorophenol and dioxin are the contaminants of concern. Remediation technologies have included soil removal and installation of two water recovery trenches that collect groundwater, which is then pumped through a granular activated carbon (GAC) water treatment system. There were …
