Federally proposed carbon emission reductions, retirement of aging power plants and a population increase of about 15M people by 2040 are expected contributors for outstripping domestic regional electricity production in five southeastern states (South Carolina, Georgia, Florida, Alabama and Mississippi). For these particular states, projections at 2040 show a population of about 56 million and an anticipated electricity shortage of about 15,000 megawatts. Alternative renewable energy sources, such as shallow water tidal currents, represent possible considerations for closing the expected shortfall.

The borehole tapping method was used to extract oleoresin from the xylem in slash pine (Pinus elliottii) in North Florida. This closed collection system allows for the recovery of higher quality resin, which can be used for a variety of commercial products as well as a natural liquid biofuel. Conifers produce oleoresin naturally as a biochemical defense against plant pests, such as boring bark beetles. The objectives of this project are to develop cost effective methods to collect oleoresin in North Florida and assess the feasibility and impact of expanding collection of pine terpenes for renewable chemicals and biofuel production on a large-scale. Treatments were applied manually using a gas powered drill as well as with an automated drilling machine mounted on a tractor designed to drill 3 connecting boreholes at the base of the tree. Oleoresin yields were compared from North Florida slash pine plantations aged 11, 15, and 22 years collected in the summer and fall. Oleoresin yields increased with stand age and DBH, as well as in stands managed for pine straw raking. Methyl jasmonate stimulated higher rates of oleoresin production compared to all other chemical stimulants.
Thermoelectric heat waste will be used to reduce the amount of fuel needed to operate the transit bus while in service. The project will apply this technology initially developed for spacecraft and transition this work to transit systems with a waste heat recovery system that is expected to generate 1000W of 24V power to support bus systems, utilizing energy that will otherwise literally be sent out the tail pipe.
Micro-CHP systems have been commercialized and used widely in Europe but their deployment is limited by the economics of having heat led operation algorithms. The heat engines used in micro-CHP systems have lower electric efficiencies than central power plants so are only used when a heat demand exists for hot water or space heating. This leads to considerable idle capacity when no local heat demand exists. This presentation discusses three methods to improve the utilization of this distributed power resource.
The second is to incorporate these distributed power resources into a smart grid so that they can be used as peaking plants and only used at periods of atypical grid performance. This method would utilize the lower efficiency electric power from micro-CHP systems to allow the grid to ride through excursions that are out of the ordinary and avoid the building of capital intensive power plants for this purpose that remain idle most of the time. 2ff7e9595c
