Remote Alaskan Energy Applications

Art Nash, Energy Specialist- UAF Cooperative Extension 1Many remote communities with disconnected electrical grids

Macro view- stranded resourcesCommercial energy resources with potentially large technical, logistical and locational challenges that have potential energy/economic value

Often Stranded due to economies of scale, transportation limitations, or seasonality (solar, hydro, wind)

Alaska Peninsula and Aleutian Islands have at least 14 identified geothermal sites >302 F with possibility of 1,000 MW of electricity over 30 years. The offshore wind potential along the Aleutian arc is tremendous; wind often augments diesel generation for Western Alaska remote grids .

5Along the southern coast of Alaska and the Aleutians wave potential is ~200 times the States total annual energy needs.

Offshore Cost Wells (Oil)

Coal

Possibility of an increase in energy demand near stranded areas (by shipping and industry)

Energy Intensive Industrieslarge base load renewable energy source

proximity to global shipping routes

presence of a deep water port

supporting infrastructure requirements

emphasis on energy export through value-added products, rather than transmission lines

Fjardal Aluminum Smelter in Iceland at 940 tons of aluminum/dayMicro view- energy for remote camp, village or lodge Supply-What fuels do you have and use?

What types of fuels do you currently use remotely?(white) gas, diesel fuel oil, propane, driftwood, cordwood

What do you use it for?Cooking, drying or canning fish on the riverbank, laundry, sanitation, refrigeration, space heating, car, truck, boat, 4 wheeler, snow machine, lighting, communications, home electronics, CB radio

What efficiency actions can you take to reduce need? bulb replacements, type of appliances, extending usage over the day to avoid concurrent load draws

Demand-How do you use energy?List the items currently that use energy at your camp/cabin

Estimate how many hours each is used and by which fuel/source

Figure out how much each uses for generator figure out start up surge, estimate peak and continuous load12Site and source considerationsHow windy is it, what times of day/year?

How much velocity or volume are there in the rivers or streams nearby?

How much direct & indirect sunlight is there? Where is the aspect usually?

Are there hot springs nearby?

Are there grasses, brush, trees or driftwood nearby?

DC charge

( allows charging to peak without overcharging) Battery backup considerations for Monitor, Toyo, Dewalt tools.Pure sine wave inverters handle igniter start-up without ruining your circuit boards on your equipment while modified wave inverters may not.
