Other Energy Programs

  • Geothermal Energy Program
  • Ocean & River Program

Alaska Energy Authority no longer funds Geothermal power projects.   We look forward to bringing the Geothermal program back online once funding is available.

Geothermal energy can be used for electricity production as well as space or process heating applications. The process of electrical production is very similar to a traditional coal power plant, except the energy is supplied by the Earth’s heat instead of the combustion of coal. In both cases, a relatively high temperature and high-pressure fluid is expanded across a turbine to provide power to a generator, producing electricity.

For a geothermal resource to be capable of economically-viable power production, a number of attributes must be present: 1) a heat source, 2) a reservoir with sufficient permeability and porosity, 3) sufficient heat conduction within the formation and 4) high enough fluid flow.

The AEA Geothermal Program produced several successful partnerships such as the Chena Hot Springs Geothermal Resource.  

 

Ocean and River Programs

Alaska Energy Authority no longer funds Ocean and River Energy Projects.   We look forward to bringing this program back online once funding is available.  

Ocean energy is divided into in-stream, tidal, and wave energy. In-stream and tidal energy technology consists of many designs, but all convert the kinetic energy of the flowing water into electricity, most using some type of turbine.

Turbine designs range from underwater wind turbine-style, to vertical- or horizontal-axis cross-flow turbines. As an emerging technology, wave energy conversion devices exist in a wide array of designs aiming to convert wave energy into electricity. While not as consistent as the tides, the amount of potential wave energy is frequently predictable days in advance.

River in-stream energy conversion (RISEC) devices work in a similar manner to tidal devices, but generally on a smaller scale.

AEA hopes we can bring back this program when funds are available to identify and overcome barriers to the advancement and deployment of hydrokinetic devices in Alaska.
