Renewable Energy Zones: Delivering Clean Power to Meet Demand, Greening the Grid
Greening the Grid provides technical assistance to energy system planners, regulators, and grid operators to overcome challenges associated with integrating variable renewable energy into the grid. This document describes the renewable energy zone concept that has emerged as a transmission planning tool to help scale up the penetration of solar, wind, and other resources on the power system.
South Africa and the 21st Century Power Partnership: Paving the Way to a Clean, Reliable, and Resilient Power System
Established in 2012, the 21CPP South Africa Programme is a global initiative that connects South African stakeholders with an international community of expertise. The overall goal of this program is to support South Africa's power system transformation by accelerating the transition to a reliable, financially robust, and low-carbon power system. 21CPP activities focus on achieving positive outcomes for all participants, especially addressing critical questions and challenges facing system planners, regulators, and operators.

Pilot-Scale Demonstration of a Fully Integrated Commercial Process for Converting Woody Biomass into Clean Biomass Diesel Fuel
The economic recovery of petroleum, like other fossil fuels, is limited. Although the current price of oil has dramatically dropped due to increased production and new production methods, it is not expected to remain low for an extended period of time as demand increases. While new methods of obtaining these fossil energy reserves are constantly being invented and introduced, the cost of production generally continues to increase. New sources of energy such as fracking and oil shale or oil sands recovery can produce enormous amounts of energy, but at a severe cost. The current estimate on energy return for energy invested for oil shale for instance is just barely over 1, meaning that for every barrel of energy produced by oil shale there was nearly a barrel of energy invested to recover it. Furthermore, these new technologies are often constantly under attack for environmental concerns (especially given the poor ratio of energy conversion), while conventional oil is regarded as dangerous due to lack of domestic supply and susceptibility to foreign intervention that compromises overall national security. Alternatives to a petroleum-based supply of fuel are a potential route to address these issues, although they must also be economically feasible. The fuels industry is forced to consider these issues in addition to federal mandates intended to gradually diversify our fuel sources.

Synthesis and characterization of low viscosity carbon dioxide binding organic liquids for flue gas clean up
Climate change is partly attributed to global anthropogenic carbon dioxide (CO2) emission to the atmosphere. These environmental effects can be mitigated by CO2 capture, utilization and storage. Alkanolamine solvents, such as monoethanolamine (MEA), which bind CO2 as carbamates or bicarbonate salts are used for CO2 capture in niche applications. These solvents consist of approximately 30 wt% of MEA in water, exhibiting a low, CO2-rich viscosity, fast kinetics and favorable thermodynamics. However, these solvents have low CO2 capacity and high heat capacity of water, resulting in prohibitively high costs of thermal solvent regeneration. Effective capture of the enormous amounts of CO2 produced by coal-fired plants requires a material with high CO2 capacity and low regeneration energy requirements. To this end, several water-lean transformational solvents systems have been developed in order to reduce these energy penalties. These technologies include nano-material organic hybrids (NOHMs), task-specific, protic and conventional ionic liquids, phase change solvents. As part of an ongoing program in our group, we have developed new water lean transformational solvents known as CO2 binding organic liquids (CO2BOLs) which have the potential to be energy efficient CO2 capture solvents. These solvents, also known as switchable ionic liquids meaning, are organic solvents that can reversibly transform from non- ionic to ionic form and back. The zwitterionic state in these liquids is formed when low polarity non-ionic alkanolguanidines or alkanolamidines react with CO2 or SO2 to form ionic liquids with high polarity. These polar ionic liquids can be thermally converted to the less polar non-ionic solvent by releasing CO2.

Method of making self-cleaning skin-like prosthetic polymer surfaces
An external covering and method of making an external covering for hiding the internal endoskeleton of a mechanical (e.g., prosthetic) device that exhibits skin-like qualities is provided. The external covering generally comprises an internal bulk layer in contact with the endoskeleton of the prosthetic device and an external skin layer disposed about the internal bulk layer. The external skin layer is comprised of a polymer composite with carbon nanotubes embedded therein. The outer surface of the skin layer has multiple cone-shaped projections that provide the external skin layer with superhydrophobicity. The carbon nanotubes are preferably vertically aligned between the inner surface and outer surface of the external skin layer in order to provide the skin layer with the ability to transmit heat. Superhydrophobic powders may optionally be used as part of the polymer composite or applied as a coating to the surface of the skin layer to enhance superhydrophobicity.
