LOW HEAD HYDRO COMPETITION
None of the low head hydro offerings of the competition are commercially viable. The reason is that none of the present systems make use of the vortex power of the moving water.
Comparisons: Key Points of Difference
1. The closest commercially viable low head hydro system is the $257 million Gorlov helical turbine system in Korea, which uses a similar Innovative Helical Technology as HUG.
2. The Power Density of the Competition is very low: the reason is that the flow of a current treats all these turbines as obstacles to be avoided. In contrast, HUG creates a negative force, which attracts the flow: the velocity in its Helical Turbine System is four time faster than the current.
3. The excessive weight causes installation problems: KORDI lost a whole year, because it’s very large unit was swept away by the tide.
4. Although the declared water to wire efficiency is in excess of 35%, none of the Competitive Offerings can exceed this high efficiency held by HUG. See graphic.
5. The Power Density of 73.5 kW/m2 tells the whole story. The velocity of the current is the reason for the difference: the Power Density increases to the cube of the velocity and the HUG velocity is four times faster than the competition.
6. The most important consideration is cost: $885/kW is unusually low compared to most other hydro electric generation systems. In 2009, Hydro-Quebec cost for 4500 MW was $5,100/kW. See the comparison chart below
OpenHydro has spent $2.2 million on their propeller system in the Bay of Fundy to date. This company has not really reported any great news about their new invention, since they installed it several years ago. The total device weighs 360 tons, which is very heavy. The power density is 2.6 kW/m2.
Verdant Power is currently installing six Gorlov turbines in New York City’s East River. Each turbine will have a blade diameter of 16 feet. Again, these turbines are simply placed in the path of a tidal flow. The Power output at 2.5 m/s is only 168 kW/turbine. The power density is only 2.8 kW/m2.
One system that is using kinetic energy is being developed with a French partner by Turbines Novatech-Lowatt Inc. in Beloeil, Quebec, which has been undergoing testing since early 2007 at a site in Millau in Southern France. They claim that only 2,000 of 80,000 dams in USA generate electricity and they can introduce a solution to this problem.
The HUG Competition
The most advanced companies from a commercialization standpoint are two European companies: Marine Current Turbines of the UK (cost unknown) and Hammerfest Strøm of Norway(Investment to date: $13.4 million). Both of these companies use a propeller style turbine, which have received significant support from their respective federal governments. They are fairly far along in the commercialization process, with working prototypes in place. A propeller style turbine has a lower efficiency of 20% compared to the helical turbine’s 35% efficiency.
OUR NORTHYDRO STRATEGY
- Stage 1 To build a small version of the HUG
- Stage 2 HUG Hydro electricity and irrigation in remote areas
- Stage 3 To capture HUG energy from Run-of-River, Rapids & Waterfalls
- Stage 4 To Introduce the HUG Water Transfer System to crisis areas
- Stage 5 To introduce commercially viable HUG Tidal Energy
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.
