Oxycombustion is a new form of "low-emission boiler" technology where the air used in combustion is replaced with oxygen and the recycled gases from gasification and water to control the temperature. The excess gas not used up is usually made mostly of carbon dioxide and it is sent away to be used elsewhere. This technology is still being developed and tweaked to make it a more viable source of power generation.
Colton Sisson's comment, April 3, 2014 7:48 PM
The main focus for new coal technology is aimed at making coal a more "green" energy source. Standard methods for using coal produce way to many greenhouse gases and this new technology is taking these gases and converting them into usable gases. This conversion makes both more energy sources and drastically lowers the amount of emissions produced.
Colton Sisson's comment, April 3, 2014 8:01 PM
To make most of these new coal technologies usable CO2 storage also needs to be found. It is estimated that the U.S. has a minimum of 2400 billion metric tons of possible CO2 storage space. Being able to capture and store this gas is pivotal in minimizing the overall effect of climate change. Multiple projects have been launched throughout the midwest to test "large-scale industrial carbon capture and storage".

Background info on coal: Coal is used for generating electricity, making steel, cement, and paper. It can be converted into liquid fuel such as gasoline, diesel fuel, and jet fuel and can be converted into a cheap heat source in the production of ethanol. Because it is involved in a large portion of our society it is hard to move away to alternative and clean energy sources. Just stopping the use altogether is not an option, we have to begin to slowly replace coals role in our products. Another reason it is hard for us to move away from it is that there is so much available. The U.S. has enough "recoverable coal reserves" to last around 250 years, our reserves make up around 27% of the entire world's coal supply.
Colton Sisson's comment, March 27, 2014 10:27 AM
"Reserves" are coal that is readily available because of continuing mining, "Resources" are areas that we are aware contain coal deposits but we have yet to mine them. U.S. coal resources are estimated to have around 10 trillion short tons, 2000 pounds per short ton, and would be able to last us around 9000 years at the current rate of consumption.

There has been research into a nano sized antenna arrays that would be capable of gathering more than 70% of the sun's electromagnetic radiation and then immediately transform this radiation into usable electricity. The problem with this technology was the manufacturing of the nano arrays. UConn engineering professor Brian Willis has created a new process called selective area atomic layer deposition (ALD). In these rectenna there are two electrodes, one with a sharp tip which must be within one or two nanometers of the other electrode. Through ALD a thin coat of individual copper atoms are added until about a 1.5 nanometer gap is created.
Colton Sisson's comment, March 13, 2014 8:06 PM
This process allows for easy reproduction of these rectennas which are very consistently made. It can also be used to enhance current photovoltaics, thermoelectrics, infared sensing, imaging, and chemical sensors. These rectennas are going to be mass produced prototypes for Willis and his collaborators to test for their efficiency to see if they are a viable option for solar panels.

New Ocean Power generation technology is in development. Ocean power is one of the most promising forms of renewable energy being "800 times higher" than the energy output of wind. This is because the waves/tide are predictable because they are controlled by the sun and the moon. This improves the planning security in electricity output. Another advantage is that as long as the current is strong these power plants can exist. Siemens estimates an output potential of 800 Terawatt hours per year, this is enough to supply around 250 million homes with clean, renewable energy.
Colton Sisson's comment, March 13, 2014 7:06 PM
Because wind turbines are often located in remote regions of the world they need advanced monitoring systems to help ensure they are always up and running efficiently. One example of these systems is Siemens WebWPS SCADA system which displays information of electrical and mechanical data, operation and fault status, meteorological data, and grid station data. This system can also regulate the active power output of the turbines. Turbine Condition Monitoring (TCM) is another example of new monitoring systems, this system continuously performs precise condition diagnostics on the main turbine components. These systems are aimed at ensuring that the turbines that are malfunctioning can get repaired and that the turbines are generating electricity as efficiently as possible.
Colton Sisson's comment, March 13, 2014 7:18 PM
Siemens Turbine Load Control 2.0 (TLC) is another advanced system which adjusts the turbines based on "real-time" operating conditions. This system will change the line of the turbines depending on the direction of the wind. This will allow for almost constant operation as long as the wind is blowing. Turbines with TLC are also able to use longer rotor diameters, which allow for larger blades and more rotation, and are able to avoid grid instability that is caused by standard sector management systems.

Stanford is researching into installing a very thin layer of organic molecules to a solar panel which increases the overall efficiency of the solar panel by threefold. These organic molecules use small particles known as semiconductors which are called "quantum dots". These dots are cheaper to produce than the standard solar cells. Another advantage to these dots is that they can be "tuned", which makes them smaller or larger, to different wavelengths which allows them to absorb multiple wavelengths of light. With this they can almost constantly be absorbing the light from the sun during the day no matter where they are.

Ohio State students and professor of chemical and biomolecular engineering at Ohio State, Liang-Shih Fan have developed a new method of chemically converting the coal to heat and also capturing almost all of the CO2 that is released. This method is called coal-direct chemical looping. In this method, coal is not burned with fire it is instead chemically combusted in a sealed chamber which captures the air pollutants. They also have a second combustion chamber which uses the pollutants.

Around 150 coal plants have either been shut down or have begun the process of shutting down since 2010. This is because of the new burst of natural gas made avaliable, which lowered the demand for coal from the low gas prices. We have been able to access more of these gas reservoirs because of new hydraulic fracturing technology. Currently natural gas is generating 30% of electricity, Water, Wind, and Solar now holds 12% with coal not much higher than natural gas.

Engineers are trying to improve overall efficiency of wind turbines in their transmissions, noise, and through new systems that maximize energy output. For example engineers are designing advanced systems to help the problems in wind variability because the wind is so unpredictable which leads to the output constantly changing. These systems will help to optimize the overall output of wind turbines so that when the wind is not blowing there is still power left over.

Colton Sisson's comment, March 5, 2014 10:25 AM
Hydrogen (H2) is one of the most promising fuel sources for the future. This fuel can be used in both electric motors or the standard internal combustion engines (ICEs). When used in the electric motors it produces zero air pollutants or green house gases. However when used in an ICE it does produce nitrogen oxides which are harmful gases that destroy the ozone.
Colton Sisson's comment, March 5, 2014 10:27 AM
These hydrogen electric motor cars are called FCVs or Fuel Cell Vehicles. These cars produce zero tailpipe emissions. In FCVs hydrogen gas is converted, with the oxygen in the air, into electricity with a Fuel Cell Stack. This converted electricity then goes to the electric motor and moves the car forward.
Colton Sisson's comment, March 13, 2014 6:23 PM
There is potential for this system to be used in a larger scale. A hydrogen tank could be built inside the power plant which would then be connected to a large fuel cell stack. This fuel cell stack would then convert the hydrogen gas with the oxygen in the air into electricity, similar to what is done in cars. But instead of the electricity immediately going into an electric car motor, the electricity could flow through power lines and to peoples homes. Although this is a very basic design if the hydrogen car design was moved to large scale it could be used to bring power to everyone.
