Researchers Dive Into the Science of London’s Deadly Fog
I asked Kumm and he thought that the cold water draw from OTEC would have no effect on a hurricane even if we built a vast number of platforms in the Gulf of Mexico. Wang's proposal was quite different, as the cryogenic storage of ammonia would allow for the production of water ice, with the albedo increase effect making dramatic changes in exchange for a relatively small amount of energy.
The energy storage schemes ranged from high level policy view provided by Bill Leighty of the Leighty Foundation to a clever solar thermal ammonia based storage loop described by Rebecca Dunn of the Australian National University.
One of the big problems in renewable energy is that wind is irregular and solar is periodic; the firming of sources such as these is vital to a conversion to an all renewable energy economy.
Alaska's Energy Authority is looking into the use of ammonia as a fuel in many locations. David Lockard's presentation was a fascinating gateway into a world already facing many of the issues peak oil will bring to all human society. Mark Huberty and his advisor Dr. Ed Cussler have taken a different approach on the firming issue, modifying a Haber Bosch reaction chamber to contain a simple ammonia absorbing salt. Once this is perfected, ammonia will be produced in small batches using wind driven electrolysis and nitrogen separation via a simple membrane plant.

The ammonia production projects were of varying caliber and maturity. The University of Minnesota Morris campus has a wind driven ammonia plant on the build but that is purely research oriented, with just a single 1. Dakota Gasification is running a coal based ammonia production facility with CO2 sequestration, the only non-renewable-energy system and the only one currently in production. Kathy Showalter of Enerjyn was the lead grant writer on this one, and they have an extensive practice in renewable energy projects.
Freedom Fertilizer's grant was written with a great deal of assistance from those involved in the Stranded Wind Initiativeand the intent was to leverage this small grant into a full scale ammonia production facility.
A year into our explorations, it is now known that the traditional Haber Bosch synthesis method must have a full time grid connection to behave properly, so we've undertaken a patent application for some modifications to Haber Bosch which will enable it to perform with an irregular power input.
I suspect both the improved Haber Bosch and solid state ammonia synthesis will be commercially viable, with the former being used in places where waste heat would have commercial applications and having a lower bound in the tens of millions of dollars as far as plant cost, while the later will be used across a broad spectrum of projects thanks to its ability to scale from a single tube up to entirely consuming the output of a large hydroelectric facility.
There were three presentations on ammonia safety. The consensus is that ammonia can be stored safely, even in urban settings, and that it'll make a passable motor fuel as well, but the Department of Energy does not view ammonia as a potential hydrogen carrier. Like so many other things in the world today, everyone is waiting patiently for an energetic new Congress and President Obama to correct these various misconceptions.
These are exciting times for renewable ammonia production given the existing demand for fertilizer and the soon to be booming need for this carbon free fuel.
This report is not an exhaustive review of what was presented but you should find all of the presentations, albeit in PDF form, in the link at the top. Likewise, inflow of the Mediterranean with salinity Within this feature, two smaller cyclonic gyres operate, occupying the eastern and western sectors of the basin. Mesoscale activity in the peripheral flow becomes more pronounced during these warmer seasons and is subject to interannual variability.
Outside of the Rim Current, numerous quasi-permanent coastal eddies are formed as a result of upwelling around the coastal apron and "wind curl" mechanisms. The intra-annual strength of these features is controlled by seasonal atmospheric and fluvial variations.
During the spring, the Batumi eddy forms in the southeastern corner of the sea.
This layer is composed of cool, salty surface waters, which are the result of localized atmospheric cooling and decreased fluvial input during the winter months. It is the remnant of the winter surface mixed layer. Below the pycnocline is the Deep Water mass, where salinity increases to Weak geothermal heating and long residence time create a very thick convective bottom layer.
During periods of high surface productivity, short-lived algal blooms form organic rich layers known as sapropels.
