In topic 11.b, Dispatchable Geothermal Operations, DOE seeks to enable more widespread deployment of geothermal as a dispatchable energy source.TerraCOH’s CO2 Plume Geothermal (CPG™) and Earth Battery™ technologies are ideally suited to meet DOE’s needs.Conventional geothermal power technology has generally been limited to use as a baseload power source, but with increasing penetration of ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at the Stanford Linear Accelerator Center (SLAC) and DoE Jefferson Lab. Future systems, such as the International Linear Collider (ILC), will require a polarized electron beam intensity at least 20 times greater than produced by strained GaAs, which is us ...

New experiments and technologies in the science of physics employ electrons with a certain and known polarization. Sources of these electrons typically have imperfect polarization less than 80 percent and low quantum efficiencies less than 1 percent. Increasing either or both of these device properties greatly enhances the physics research being undertaken in facilities such as high energy collide ...

Since 1990, the cost of hydrogen needed to treat one barrel of oil has increased from 10 cents to $1. This problem is being exacerbated because of stricter environmental regulations and because the crude now being processed by refiners contains less hydrogen and more sulfur. To deal with the hydrogen shortage, most large refineries have outsourced their hydrogen generating capacities to industrial ...

The primary challenges for creating renewable fuels are the ability to process inexpensive non-food feedstocks into biofuels that meet all quality specification, perform indistinguishably from petroleum-based fuels and are compatible with current infrastructure.Our Phase I project demonstrated the feasibility of producing biofuels from waste greases using a novel hydrothermal, continuous-flow cata ...

Automobiles (cars and trucks for instance) are the predominant mode of transportation in the United States. These vehicles are powered by internal combustion engines that consume fossil fuels such as gasoline. Improving the efficiency of internal combustion engines is an ongoing challenge of enormous impact to energy consumption in the world. In order to improve engine efficiency and thus fuel eco ...

Friction and wear are energy-robbing processes that represent a tremendous burden to the national economy, especially in this time of record oil/fuel prices. Unfortunately, the field of tribology (the science of friction, lubrication, and wear of interacting surfaces in relative motion) lags many other disciplines in terms of fundamental knowledge. What is needed is a new tool that enables tribol ...

In situ tensile testing in the transmission electron microscope (TEM) has been a powerful tool for revealing underlying physical mechanisms at the nano or even atomic scale when materials are subjected to an applied stress. However, all commercially available in situ TEM tensile holders suffer from the absence of quantitative ability and require complex sample preparation. This project will deve ...

In atmospheric aerosol research, size-distributed aerosol samples are often collected with airborne instrumentation, but are not analyzed in any manner until after they are brought to a laboratory on the ground. The information thus obtained is averaged for all the locations covered during the mission. A novel technology is being developed in this project to constantly measure the size-distributed ...
