A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

Full Text:: development of hydrogen as a fuel since the 1970s to divert a segment of the energy market from fossil fuels

Fabrication of precipitation-hardened aluminum microchannel cooling plates for adsorption-based hydrogen storage systems

Creator:: Pawar, Supriya V.
Abstract:: The need for clean and renewable fuel such as hydrogen is driven by a growing worldwide population and increasing air pollution from fossil fuels. One of the major barriers for the use of hydrogen in automotive industry is the storage of hydrogen. Physisorption is the most promising storage technique due...

Heat transport at interface in the metal-organic-frameworks MOF-5

Creator:: Huang, Wenxi
Abstract:: The metal-organic–framework MOF-5 is used as an adsorbent in advanced systems for vehicular hydrogen storage that are currently under development. Presently, these systems are limited by poor thermal conductivity of the adsorption bed, and thus our research addresses how the interfaces between grains of MOF-5 can be engineered to improve...

Hydrogen production via a sulfur-sulfur thermochemical water-splitting cycle

Creator:: AuYeung, Nicholas J.
Abstract:: Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...

Compact integrated microchannel combustor, recuperator and heat exchanger For hydrogen storage applications

Creator:: Ghazvini, Mohammad
Abstract:: A novel microscale combustor-heat exchanger (μCHX) for hydrogen storage applications is presented in this dissertation. The design of the μCHX is motivated by its application to two particular systems for automotive use- those that utilize metal hydrides (MH) and cryo-adsorbents (CA) to store hydrogen. Thermal energy needs to be supplied...

Detailed analysis of the hydrogen sulfide production step in a sulfur-sulfur thermochemical water splitting cycle

Creator:: Caple, Kevin R.
Abstract:: The production of hydrogen has been one of the most heavily studied, energy related fields over the past half century, yet few methods are commercially or economically viable and none are currently sustainable. Of those aiming at the sustainable production of hydrogen using renewable resources, perhaps the most widely studied...

Microbial Electrolysis Cells for the Production of Hydrogen Gas : Evaluation of Internal Resistance and Design for Scale-Up

Creator:: Miller, Andrew G.
Abstract:: Modification of microbial electrolysis cells (MECs) by altering the sizes of the anode and the cathode, or their interaction with the liquid stream affects the performance of the MEC, but it remains difficult to quantify how much each change will contribute to the overall performance. Through this study, a method...

Using a membrane reactor for the sulfur-sulfur thermochemical water-splitting cycle

Creator:: Knapp, Nathan Michael
Abstract:: The hydrogen economy is a possible component of an energy future based on use of alternative and renewable energy sources, deemed desirable from the general consensus of the worldwide community that we do not want to further exacerbate the climate problems that we have introduced over the last two centuries...
Resource Type:: Masters Thesis
Full Text:: not have as many storage problems that electricity has. On site fuel cell systems can be used to

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...
