The Diesel Plant Dilemma
As of 2014, there were approximately 17 generating plants that had reached the end of their designed service life. Many of the diesel plants were once owned by the federal government via the Northern Canada Power Corporation and extensive damage can result due to freezing.
For example, four generators had to be airlifted using specialized Russian aircrafts: a large cargo aircraft and a specialized 70 foot-long twin engine helicopter.92 The cost of the operation (not including the cost of the generators) was roughly $3 million.
A new 7 MW generator can be added, which will save $1.2 million in diesel costs and reduce greenhouse gas emissions by 3,800 tonnes a year.
The residential electricity rate in Nunavut varies between 30.14 cents per kilowatt hour (kWh) to 114.16 cents per kWh compared to the national average of 12.13 cents per kWh.
Northern Economic Growth
Currently, mining operations in the NWT are powered by on-site diesel electric generation. These costs make up 10% to 30% of the capital costs of a new mine. Ongoing electricity generation (fuel & maintenance) makes up 20% to 30% of the production (marginal) costs of a mine.
A typical mine in NWT has an electrical load averaging 10 MW.
- Lower cost of operations • Annual electricity purchase costs less than half the cost of diesel fuel costs • Lower Levelized Cost of Energy LCOE,
- On a present value basis >$100M savings in electricity related costs over the 15 year mine life.
Costly Transmission Lines
In recent years, all three territories have studied projects that would connect them to the southern power grid, and all three have backed off because long-distance transmission lines are too expensive.
The key sensitivities in line length are the price of diesel and grid-based electricity. • A 250 km transmission line could be built for the same life cycle energy costs (capital, O&M) when purchasing $0.15/MWh power and offsetting power generated with $1/L diesel.
- The supported line length is reduced to 70 km if the price of power is $0.30/MWh and diesel remains at $1/L.
Costly Hydro Dams
Meanwhile, Nunavut, which is solely-reliant on diesel, has pursued hydroelectricity for years, but simply cannot afford the hundreds of millions of dollars it would cost to build hydro dams to supply Iqaluit and, possibly, the Kivalliq region.
Officials with Natural Resources Canada told senators they’re open to considering loan guarantees.
Providing access to low-cost reliable hydroelectric power is effectively a prerequisite to enabling robust regional economic development
The goal of providing grid power to mines is to be a catalyst for economic growth by enabling new mines to start-up and to extend the life of existing mines.
Low Head Damless Hydro: the Solution of the HUG!
To introduce commercially viable HUG Energy
This is a new business or joint venture for the purpose of DEVELOPING AN ENTIRELY NEW GOOD — the HUG!
Presently no new patents exist to capture energy efficiently from small waterfalls or fast rapids or even rivers without limiting fish migration.
CASE STUDY: Avalon Rare Minerals Inc.
Avalon Rare Minerals Inc. recently completed a feasibility study for the Nechalacho property. Since acquiring Nechalacho in 2005, Avalon has raised over $100 million in equity financing and invested about $90 million in the project. An environmental assessment report was also approved by the federal government on November 4, 2013.
NWT officials are asking the Harper government to increase their borrowing limit so that new power facilities – notably a hydro generator and transmission lines – can be built. The Yukon is seeking federal funding for a new $100-million dam (the site has not been chosen yet).
Avalon Rare Minerals Inc. is commiting to the use of line power as the main source of power for the Hydro Metallurgical Plant. On average, approximately 7.3 MW of power is required for the Hydro Metallurgical Plant which will be supplied by excess hydroelectric power from the Taltson Dam most of the year except during winter when supply is limited to about 6 MW and the remainder will be generated by diesel power. Yet look how far the Taltson Hydro Dam is to the mine site: 180 km
The HUG is within 60 km away and it creates hydroelectric energy at a fraction of the cost of a Hydro Dam from the Snake River.
HUG (Helical Unique Generation) is an Innovative New Design, which could put clean, river-friendly power within reach of everyone. It produces high energy from a hydroelectric turbine system, which in turn, generates a high return of investment.
Why not just build a dam? There are many situations where
(1) Damming of the flowing water is prohibitively expensive
(2) It is impossible because of soil conditions
(3) It is impracticable because of navigational needs for the flowing water.
Small batches of HUG turbines can be installed with only a short period of 12 to 18 months between investment in the technology and the time when revenue starts to flow: it is modular, relatively easy to install and highly scalable.
So what is the Secret of the Vortex?
The Cycloid Spiral Motion in a HUG forces the flow to “roll” inward around the axis of motion of the water’s flow. This natural kind of motion tends to accelerate and align the stream of water along its path. This creates a boundary layer along the inside of the HUG Spiraling Pipeline that makes it possible to create zero friction in a laminar flow. The result is a doubling and quadrupling of the velocity of the laminar flow that increases the kinetic energy of the helical turbine, which is located at the end of the HUG.
This is best seen by the Kinetic Energy Formula with respect to Velocity:
The most critical factor is the Velocity of the flow. A tripling of the Velocity from 2.5 m/s multiplies the Kinetic Energy (KE) by 3³ or 27 x, by the formula:
KE (Kinetic Energy) = ½ x A x V ³ x efficiency (A = area swept; Velocity)
= 0.5 x 3.26 m² x (7.72 m/s)³ x 35% = 260 kW/turbine
GREEN HYDRO POWER STATIONS The installation of most of very low head sites is technically feasible, but civil works give rise to high costs, resulting to economically enviable projects. To solve this problem, one must design a new machine using a completely different philosophy to equip such sites. The study of current turbines reveals that they were all invented on the basis of a poor understanding of hydrodynamics, and a consequent false premise.
MOBILE HUG: The HUG development is an exciting breakthrough in green energy. Small batches of HUG turbines can be installed with only a short period of 12 to 18 months between investment in the technology and the time when revenue starts to flow: it is modular, relatively easy to install and highly scalable.
PRE-FABRICATED HUG Standardized pre-fabricated modules should make it possible to order this new product as a “power plant kit” just like ordering from a catalog. The HUG power plant uses standardized parts, so no custom engineering is necessary. A one-size-fits-all pathway could be ordered.
Why is the HUG Frictionless? When we direct the water to flow at its natural mode, it hugs the inner wall. This kind of vortex motion tends to accelerate and contract the stream of water. The less collisions improves the flow, i.e. the better ordered and more dense the flow will be. The net result is that the velocity of the flow in the HUG is four to five times faster than the river velocity.
