Energetically Enhanced Reforming Process

UCLA researchers from the Department of Chemical and Biochemical Engineering have developed a method of generating hydrogen through steam reforming that does not require the large amounts of applied heat needed in conventional reforming processes.This presents the opportunity to greatly reduce operational costs associated with hydrogen generation.The method does not introduce air or oxygen to the reforming mixture, thereby avoiding the explosion hazard that is introduced by autothermal reforming.

Recirculating Noble Gas Internal Combustion Power Cycle

Conventional power conversion cycles which turn fuel into heat and heat into power are constrained by basic thermodynamic considerations. The most modern technologies have been limited to 60% even with multiple cycles combined (i.e. Brayton and Rankine combined cycle). Recent demonstrations have shown relative efficiency gains of 30% in both spark-ignited and compression-ignited regimes. Researchers at the University of California, Berkeley, are working to outdo these efforts by working on an ultra-high efficiency power cycle framework using argon as the working fluid. Early laboratory results suggest the argon engine could easily achieve 70% or greater thermal efficiency. Under such research the argon replaces nitrogen as the working fluid and is recycled in the closed-loop system.

Next-Generation Metal-Organic Frameworks With High Deliverable Capacities For Gas Storage Applications

There are many applications that require the storage of a high density of gas molecules. The driving range of vehicles powered by natural gas or hydrogen, for instance, is determined by the maximum density of gas that can be stored inside a fuel tank and delivered to the engine or fuel cell. In certain situations, it is desirable to lower the pressure or raise the temperature needed to store a given amount of gas through the use of an adsorbent. Developments in next-generation adsorbents, such as metal-organic frameworks and activated carbons, have shown certain weaknesses in terms of the amount of gas that can be delivered when an application has a minimum desorption pressure greater than zero and when a significant amount of heat is released during adsorption or cooling occurs during desorption. To help solve these problems, researchers at the University of California, Berkeley, have developed a next generation of materials using novel porous metal-organic frameworks that demonstrate unprecedented deliverable gas capacities. These engineered adsorbents maximize the amount of gas delivered during each adsorption/desorption cycle. This shows promise in developing next generation gas storage materials for applications with a wide range of operating conditions.

Microstructured Cathode for Self-Regulated Oxygen Generation and Consumption

UCLA researchers have developed a cathode that generates oxygen, consumes the oxygen as needed, and stops the oxygen generation when it is not consumed, all in a self-regulated fashion.
