Emerging Energy Technology Fund Program Prospectus
Program Description
The Alaska State Legislature created the Emerging Energy Technology Fund (EETF) in 2010 to promote
the expansion of energy sources available to Alaskans. EETF grants are for demonstration projects of
technologies that have a reasonable expectation of becoming commercially viable within five years.
Projects can:
test emerging energy technologies or methods of conserving energy;
improve an existing technology; or
deploy an existing technology that has not previously been demonstrated in the state.
Eligible technologies include those that promote, enhance, or expand the diversity of available energy
supply sources or means of transmission, increase energy efficiency, or reduce negative energy-related
environmental effects. This includes technologies related to renewable sources of energy, conservation
of energy, enabling technologies, efficient and effective use of hydrocarbons, and integrated systems.
Project funding is money appropriated by the legislature, gifts, bequests, contributions from other
sources, and federal money appropriated to the Fund. Thus far, $11.6 Million has been committed to
the Program with Alaska and the Denali Commission investing $6.8 and $4.8 Million of State and Federal
funds respectively. An additional $4.7 Million was dedicated by the award recipients and project
partners.
Data collection is a central component of all EETF awards and $1.1 Million has been devoted to this
effort. Under an agreement with the University of Alaska, performance data generated by projects are
independently verified and analyzed by the Alaska Center for Energy and Power (or another
independent third party, as needed). As projects conclude, summary reports and non-sensitive data are
made available to the public.

____________________________________________________________________________________
Project selection for the EETF program uses a two-stage application process and a volunteer advisory
committee appointed by the governor. In the first stage, brief project abstracts submitted in response
to a funding solicitation are reviewed by the advisory committee and the Alaska Energy Authority.
Select applicants are then invited to submit full applications and give in-person presentations to the
committee.
Applications are scored and ranked on a range of criteria including the quality of the innovation, the
method of validation, and the public benefit and market potential for the proposed technology. Priority
is given to projects demonstrating potential for widespread deployment, partnerships with post-
secondary institutions, Alaska entities, and projects committing in-kind or matching funds.
In 2012, 15 projects were awarded over $8 million in grants in Round 1 of the Emerging Energy
Technology Fund. The state funds available for awards was nearly doubled by a matching contribution
by the Denali Commission, a federal agency. A wide range of technologies were selected for funding,
including energy storage, building efficiency, biomass, wind generation, and river hydrokinetics.
In 2014, Round 2 project selections of an additional 5 projects with a focus on energy storage and
heating efficiency were announced.

Arctic Field Testing of the Eocycle EO-25/12 Wind Turbine
Project Lead: Northwest Arctic Borough Location: Kotzebue
The Northwest Arctic Borough is demonstrating the cold weather capabilities of a 25 kW wind turbine
at the Kotzebue wind farm. The turbine is mounted on a tilt-up monopole tower that uses a winch to
raise and lower the unit during installation and for maintenance, eliminating the need for a crane.
Project Status
The turbine and tilt-up tower arrived at Kotzebue on the last barge of 2013 and the project team was
able to take advantage of an existing unused tower foundation to the mount the turbine.
Commissioining began in late 2013 and continued for the next year with extensive troubleshooting as
numerous problems were encountered including: overheating in the nacelle, a problem with the
brake assembly shutting down the turbine, converter failure and data/communication issues. The
turbine has been operational since November 2014.
Assembling the tower Installing turbine blades
What’s Next
Performance data will be collected for one year. A fully instrumented meteorological tower will be
installed within five rotor-lengths of the tower to collect baseline wind data as the turbine generates
electricity.

Ultra-Efficient Generators & Diesel Electric Propulsion
Project Lead: Genesis Machining & Fabrication Location: Kodiak
Genesis Machining and Fabrication is demonstrating two core technologies, the Power Dense Motor
and Universal Modular Inverter Controller, for use in both stationary power generation and propulsion
applications. The technologies are being concurrently developed and demonstrated in stages using
prototypes of increasing in size and capacity that will be used to power electric vehicles and gensets of
varying sizes. Ultimately, the team hopes to demonstrate that its approach to variable speed
generation and diesel-electric propulsion offers efficiency gains over traditional technologies.
Project Status
In the first year, the team demonstrated the functionality of the inverter in an electric vehicle testbed
which has logged over 1,000 Kodiak road miles. A proof-of-concept 15 kW load matching genset which
delivers power via the inverter was also built and demonstrated. Work has since focused on design of
the next generation inverter module prototype for installation in a Diesel-Electric bus testbed. A 275
horsepower engine has been acquired along with a 50 horsepower motor for conversion into a power
dense generator head and another motor for propulsion.

Monitoring performance in the EV testbed
What’s Next
Once assembly of the next generation inverters is complete, the team will set about installation and
integration of the technology into a Diesel-Electric bus testbed. The testbed will house a genset
employing both core technologies (inverter and power dense motor) for propulsion and stationary
power generation. The project team has also filed for several patents and reached out to potential
investors in anticipation of commercialization.

Arctic Thermal Shutters & Doors
Project Lead: Arctic Sun, LLC Location: Fairbanks
Arctic Sun, LLC is demonstrating energy efficiency improvements of homes in colder climates using
arctic doors, arctic shutters and blown-in insulation shutters. Maintaining climate control in arctic high-
efficiency housing has been challenging because of high condensation on doors and windows. The
technological improvements proposed by Arctic Sun include improving R-values in the arctic doors;
creating exterior arctic shutters that are controlled by an electric drive and use air-tight weather
stripping; and shutters for retrofitted fixed-pane windows that can be automatically filled and emptied
with insulating beads.
Project Status
The project team has completed design, component selection, and prototype construction of the arctic
door and two shutter types. A fully instrumented dedicated testing structure was designed and
constructed for comprehensive performance monitoring; baseline data was collected in advance of
installation of the arctic shutters. For the blown-in shutter cavity, solid extruded polystyrene (EPS)
beads were selected as the fill material, and subjected to ultra-violet resistance testing over the course
of the summer. After undergoing design revisions, all components have now been field installed and
performance data is being gathered.

Cold Climate Heat Pump Demonstration
Project Lead: Cold Climate Housing Research Center Location: Fairbanks
The Cold Climate Housing Research Center (CCHRC) is demonstrating the potential for ground source
heat pumps (GSHPs) as an efficient and economic heat source in colder climates. This project will
install a GSHP at the Cold Climate Housing Research Center’s research and testing facility in Fairbanks
in a narrow band of thawed ground. Several different surface treatments will be modeled and tested
to maximize surface heat capture during summer months and to prevent winter heat loss.
Project Status
The horizontal loop field was installed and buried along with a network of thermcouples at varying
depths. The heat pump unit was then installed and fully comissioned. Different surface treatments
have been installed above selected areas of the ground loop including several gravel types and grass;
a fence has been installed around the area to minimize snow compaction and maximize wintertime
insulation. During the first year, the heat pump operated with an average Coefficient of Performance
of 3.6. The system is now gathering its second heating season of performance data.

Installation of the slinky loop
What’s Next
With installation complete, the remainder of the project will consist of data collection of the system’s
performance, monitoring the loop field for thermal degradation, and comparison of the effect of the
different surface treatments on the thermal health of the loop field. Data collection for the EETF
project will continue through the 2015-2016 heating season.

Safe and Efficient Exhaust Thimble
Project Lead: UAF - Institute of Northern Engineering Location: Fairbanks
The Institute of Northern Engineering is demonstrating a new design of ventilated exhaust thimbles
for wood stoves, oil-fired furnaces, diesel generators and other high-temperature exhaust-generating
sources. Stove thimbles prevent wood framing from igniting from the hot exhaust flues pass through
the building envelope. In this project, the traditional thimble will be replaced with one that relies on
thermal siphoning for passive cooling. The new design building eliminates heat loss that accompanies
traditional thimbles by maintaining integrity of the building’s envelop.
Project Status
The project team has completed final design and computational fluid dynamics modeling of the
exhaust thimble, modified a conex container for testing, and constructed prototypes of varying sizes.
Testing has been completed for each prototype size under a range of temperature conditions.

Wind-Diesel Battery Hybrid for Kwigillingok
Project Lead: Intelligent Energy Systems Location: Kwigillingok
Intelligent Energy Systems is demonstrating the use of high-performance lithium ion batteries, similar
to those found in some electric vehicles, to provide short-term energy storage in Kwigillingok’s wind-
diesel electrical system.
Project Status
A lithium ion battery manufactured for use in electric cars was selected and delivered by barge to
Kwigillingok in the fall of 2013. An abnormally warm winter delayed freeze-up and transportation to
the installation site. Commissioning, started in 2014, continues as unrelated issues with the wind
turbines, diesel generators, and distribution system have presented challenges and delays. The
battery system was operational for two weeks before a genarator failure precluded sufficient wind
contribution; during the two weeks, however, the grid was able to transition to wind-battery mode 8
times for a total of 42 hours of diesels off operation.

Transport to the installation site
What’s Next
Improvements to the powerhouse are critical prior to project continuation. Repairs on one generator
are underway and a replacement generator will be purchased and installed by the utility in coming
weeks, after which commissioning will continue and performance data will recorded and analyzed.

St. Paul Flywheel Demonstration
Project Lead: TDX Power Location: St. Paul
A flywheel energy storage system manufactured by Beacon Power will be integrated into an isolated
wind-diesel microgrid and operated to facilitate extended diesels-off electricity generation. A
successful demonstration could pave the way towards higher wind penetration rates and increase the
value of the power contributed by renewables into hybrid systems.
Project Status
After factory acceptance testing, the flywheel was barged to St. Paul and installed and commissioned
in late 2014. The system has been operating and collecting data since December 2014 and ample
winter winds have enabled significant periods of diesels off operation. Frequency regulation is being
provided by a load regulating boiler and voltage regulation is provide by a synchorous condenser
(both installed and operational prior to the project).

Project Lead: Cold Climate Housing Research Center Location: Juneau, Wrangell, Dillingham
The performance of a new generation of air-source heat pumps will be demonstrated in an effort to
provide energy efficient space heating for Alaska’s cold climates and better define the potential
geographic range for economic operation of the technology. Cold Climate Housing Research Center
instrumented three air source heat pump installations in order to determine performance over the
2014-2015 heating season.
Project Status
The project team has design and installed comprehensive instrumentation packages on the three
heat pump systems and has been monitoring performance. Nearly thirty additional systems are being
monitored for electrical consumption as a part of the proejct.

Biomass Reforestation of Boreal Forests
Project Lead: Alaska Division of Forestry Location: Palmer, Delta
The Alaska Division of Forestry is demonstrating a low cost planting technique intended for forest
regeneration after a biomass harvest that uses un-rooted poplar tree stem-cuttings. Although less
energy-dense than other biomass fuel stocks, poplars have much faster growth rates. The technique
involves the wintertime collection of branch cuttings that are stored and then planted as stems after
snowmelt. Stooling beds will also be planted to facilitate future stem harvests of species that are found
to thrive over the course of the project.
Project Status
The project team harvested cuttings during the winter of 2013 which then underwent a pre-soak
treatment in advance of planting in the late spring at sites in the Matanuska-Susitna Valley and near
Delta. Unfortunately, abnormally hot and dry conditions during the summer of 2013 resulted in a very
high mortality rate of the planted cuttings. However, cuttings at the wettest site fared significantly
better, and the project team noted higher survival rates among hybrid species. A replanting of 4 poplar
varieties in 2014 resulted in significantly higher survival rates.
Winter poplar cuttings
Pre-soaking cuttings in preparation for planting
What’s Next
Survival will be evaluated after the 2014-2015 winter and all plantations will be evaluated for growth
at the end of the 2015 growing seasons. Results will be compiled into a final project report.

BRI Cyclo-Turbine Hydrokinetic Demonstration
Project Lead: Boschma Research, Inc. Location: Igiugig
Boschma Research, Inc. (BRI) demonstrated a 5 kW River In-Stream Energy Conversion (RISEC) device
in the Kvichak River at Igiugig. The cycloidal turbine is housed within an open-ended venturi
enclosure with a fish/debris guard at the entrance. Intended to be mounted on the river bottom in
shallow water, the device’s frame uses buoyancy chambers for river transport which are filled with
water to submerge the device to its final position.
Project Status
The project is now complete. The turbine was constructed in 2013 and deployed in the Kvichak River
in the summer of 2014. The project team experience numerous difficulties manuvering in the device
in the swift moving water; once positioned, moored, and sunk in place, the anchor slipped causing
damage to the housing and communications cables. Ultimately, however, the device was able to
operate, generate electricity, and feed power into the Igiugig grid for a brief time at the end of the
permitted period.

Project Lead: Hatch Location: Fairbanks
Hatch demonstrated a lightweight high-power flywheel which could be used to provide grid stability
in wind-diesel systems.
Project Status
The project team collected one month of high resolution baseline data from Nome’s wind-diesel
system which was used in modelling and controller programming. The flyhweel was installed in a
simulated grid at the Alaska Center for Energy and Power’s Power System Integration lab in Fairbanks
for a series of trials that characterized the response of the flywheel system and its capability of
supporting the grid using the lab’s grid-forming inverter.
What’s Next
The tests are complete and the project team has compiled a final project report that is currently
under review. An independent report assessing performance data will be completed by ACEP.

RivGen Power System Hydrokinetic Demonstration
Project Lead: ORPC Alaska, LLC Location: Nikiski, Igiugig
ORPC proposes to demonstrate the RivGen hydrokinetic device, a river bottom-mounted River In-
Stream Energy Conversion (RISEC) device. The device is mounted on a redesigned pontoon support
structure, which consists of a mounting frame resting on buoyancy chambers that can be filled and
emptied of air for controlled submerging during deployment and floatation during retrieval.
Project Status
ORPC refursbished and dry-tested its first generation device prototype and completed modeling and
redesign of the support structure in 2013. After testing of the support structure in Cook Inlet in 2014,
the device was shipped by barge to Igiugig for summer deployment. The device was successfully
submerged and operated, generating up to 13 kW. An issue with the inverter prevented synching
with the Igiuig power grid, however, the project team has identified additional funding for a follow up
deployment in 2015.

Oceana In-Stream Hydrokinetic Demonstration
Project Lead: Oceana Energy Company Location: Nenana
The Oceana Energy Company is demonstrating a barge-mounted River In-Stream Energy Conversion
(RISEC) device in the Tanana River. Originally intended for tidal power applications, the
demonstration will verify performance under harsh the conditions typical of Alaska rivers. The
turbine uses an open ring design, with blades located on both the inside and outside of the structural
ring.
Project Status
The project team completed a redesign of the first generation protoype (built and tested prior to this
project), constructed a unit for testing, and performed tow testing to establish a performance
baseline in the Carderock David Taylor Model Basin in Maryland prior to shipping the unit to Alaska.
Next, the unit was deployed from a testing barge at the Alaska Hydrokinetic Energy Research Center
river testbed in the Tanana River at Nenana. The unit was operated over the course of 2 weeks,
dissipating power to an onboard load bank.
Tow testing Lowering into the Tanana River
What’s Next
The unit is undergoing inspection and minor modifications are planned during the winter prior to a
second season of testing in the Tanana River. Project completion is scheduled for the end of 2015.

available from heat pumps using traditional refrigerants.
Project Status
The project team has surveyed available CO2 heat pumps units and completed initial design of the
system. Procurement of long lead items has begun. The system will provide space heating for the
building and additional sidewalk snowmelt heating, working in conjunction with the building’s existing
heating system, which use seawater source heat pumps with a traditional refrigerant.
What’s Next
Final engineering and installation of the system is scheduled to take place during 2015. The system
will then collect performance data over the course of a heating season.

Marsh Creek is demonstrating the use of a permanent magnet “soft clutch” coupling in a diesel
genset to facilitate engine operation at speeds of both 1200 and 1800 rpm. Operating at a lower
rotational speed when power demand is low could significantly increase fuel efficiency.
Project Status
The project team has modelled performance, designed the system architecture, and constructed a
prototype. Basline efficiency testing was conducted at 1200 and 1800 rpm, but excessive mechincal
vibration prevented complete testing of the transition between the speeds.
Coupling system design Prototype testing
What’s Next
The team has been designing a mechanical solution to address vibration and will resume testing early
in 2015.

Enhanced Condensation for Organic Rankine Cycle
Project Lead: UAF - Institute of Northern Engineering Location: Fairbanks
The Institute of Northern Engineering seeks to demonstrate a technology that could improve the
efficiency of Organic Rankine Cycle (ORC) systems by increasing the heat transfer rate of the
condenser. A hydrophobic coating will be patterned onto the condenser to create a heterogeneous
surface, reducing film formation on the condensing surface.
Project Status
The project team has completed design and construction of a testing apparatus that will be used to
measure the efficacy of the hydrophobic coating that will be applied to give the condenser a
heterogeneous surface. Instrumentation calibration and preliminary baseline testing of the
apparatus revealed an issue with leaking. The leaks were identified and repaired and performance
data collection is underway.
What’s Next
When instrumentation has been calibrated and baseline data collection completed, the effect of
different hydrophobic coatings on heat transfer coefficient will be demonstrated.

High Capacity Airborne Wind Turbine
Project Lead: Altaeros Energies, Inc. Location: Fairbanks
Altaeros Energies, Inc. proposes to demonstrate a 30 kilowatt (kW) wind turbine suspended 1,000
feet above ground in a helium-filled shell. The project seeks to take advantage of higher and more
consistent wind speeds and to demonstrate an improved capacity factor relative to tower-mounted
wind turbines. By tethering to a portable trailer, a substantial decrease in installed capital costs is
expected. Altaeros plans to commercialize both 30 and 100 kW models.
Project Status
Altaeros has identified candidate sites throughout Alaska, visited a selection of sites, and selected the
Eva Creek wind farm as the deployment site. In Maine, construction and testing of a half-scale
prototype has progressed and the project team has raised additional capital to complete full-scale
construction.
What’s Next
Permitting from FAA is the critical next step for the project. The agency has been drafting policy
regarding airborne wind energy system deployment, and extended testing of any system awaits
clarification from FAA regarding the permitting process.
Multi-Stage Energy Storage System
Project Lead: Chugach Electric Association Location: Anchorage
Chugach Electric Association will use a pilot-scale energy storage system to demonstrate the technical
