Electrifying Unpowered Dams

DANGEROUS DECOMMISSIONED DAMS

Around the world, some 5,000 large dams are now more than 50 years old, and the number and size of the dams reaching their half century is rapidly increasing. The average age of dams in the US is now around 40 years. According to a panel on dam aging at ICOLD’s 1991 Congress, “in the future attention and activity [will] be more and more shifted from the design and construction of new dams to the restoration of the structural and operational safety of existing dams”.  Many of these are decommissioned dams.

Dangerous dams, however, are far from purely a problem of the ex–Soviet republics. Between 1977 and 1982 the Corps of Engineers inspected 8,800 non–federal dams in the US, most of them privately–owned, which it classified as “high–hazard” – where a failure could cause significant loss of life. One–third of these dams – 2,900 – were considered to be “unsafe”, primarily because of inadequate spillway capacity. A 1994 survey showed at least 1,800 non–federal dams were still unsafe. The situation is similar for federal dams: in 1987 one–fifth of BuRec’s 275 dams were classified as unsafe, as were one–third of the 554 dams operated by the Corps of Engineers.

An Ontario Hydro study of data from several hundred North American dams shows that on average hydro dam operating costs rise dramatically after around 25–35 years of operation due to the increasing need for repairs. When the cost of maintaining an old dam exceeds the receipts from power sales, its owners must decide either to invest in rehabilitating the dam, or, if the cost of repairs would be prohibitive, to disconnect the dam from the grid and cease producing power.

 As discussed, small dams and small dam owners collectively, represent as great a risk to the public as large dams and large dam owners, if not more so.

OCEAN WAVE ENERGY: WAVING GOOD BUY?

 

OCEAN WAVE ENERGY
OCEAN WAVE ENERGY

THE idea of extracting energy from an ocean wave and turning it into electricity is an alluring one. It has the potential to fill in the gaps that are left by wind and sun power plants when it is calm and dark.

 We calculate that the cost of producing electricity from the HUG will be around $0 .003 kilowatt hour. That compares with 16 cents a kilowatt hour for offshore wind farms, six cents for the onshore variety and a grid-connected fossil-fuel power station at five cents or more.

 HUG Wave Energy Systems are ultra-simple, only three moving parts: the helical turbine, the submersible pump and the electric generator (which is accessible and kept dry).  The simple HUG design will operate for decades with no more maintenance than an occasional scrub to remove accumulated barnacles.

The HUG uses higher waves to fill a higher reservoir to a greater water level than the surrounding ocean. The lower Pump HUG has a helical turbine, which engages a submersible pump in order to send water up a HUG pipeline to a second Funnel HUG above the water line on its own barge where its second helical turbine engages an electric generator in a dry environment.

The real advantage of the HUG is POWER from the action of the vortex in the HUG and the Venturi effect created by the shape of the HUG:

GREEN ENERGY

Green energy is the way of the future. Look at the Fossil Fuel and Renewable Energy Subsidies.

Coal, natural gas, and oil accounted for 87 percent of global primary energy consumption in 2012.

Our energy needs are growing to such an extent that we are forced to use whatever we have at our disposable without looking at the cost/damage. We are so dependent on conventional sources that the need to change often isn’t there.

Fossil fuel subsidies reached $90 billion in the OECD and over $500 billion globally in 2011. Renewable energy subsidies reached $88 billion in 2011. The IMF estimates that for 2015 the economic cost of energy subsidies worldwide will amount to US$5.3 trillion. This is not to be confused with actual amount of subsidies which are projected to amount to around US$333 billion for 2015. Without fossil fuel subsidies, the price of electricity by about 1.2 cents per kilowatt-hour. 

There is no such thing as clean coal, it’s a lie. If you think coal is great, why don’t you go live in Beijing and soak up some of that super clean air.

Hydroelectric energy This form uses the gravitational potential of elevated water that was lifted from the oceans by sunlight. At this time, most of the available locations for hydroelectric dams are already used in the developed world.  Hydroelectric  energy SUBSIDIES receive $0.01/ kWh.

Electricity: the Dominant Energy

Big Hydro’s Big Days are behind us

The $6.5-billion Romaine ” big hydro” development in Quebec, Canada will produce 1,550 MW: $4200/kW. British Columbia’s plan to build a new $8.8-billion hydro project on the Peace River for 1,100-megawatt: $8,000/kW. Manitoba may be in the worst shape of all: it has green-lighted the $6.5-billion, 700-megawatt Keeyask dam: $9286/kW (9 cents per kilowatt-hour).

The average cost of electricity from a hydro station larger than 10 megawatts use to be $1,000-$5,000/kW (3 to 5 U.S. cents per kilowatt-hour). The HUG$954/kW

There are additional indirect costs: damming interrupts the flow of rivers and can harm local ecosystems, and building large dams and reservoirs often involves displacing people and wildlife.

Cheap and abundant U.S. natural gas, with its lighter (than coal) carbon footprint, is eating Canadian hydro’s lunch. Export prices averaged 6.5 cents per kw/h in 2008. By 2012, that was down to 3.1 cents per kw/h – far below the production costs of any new hydro projects being built now.

Comparisons of life-cycle greenhouse gas emissions or global warming, which uses the global warming potential unit, the Carbon dioxide equivalent(CO2e)/kWh: 400 for natural gas and 700 to 1000 (without scrubbing) for coal.

HUGE HUG INNOVATION

innovationDAM INNOVATION

Breaching a DamOne other solution is a breach of the dam. A breach allows part of the dam to be removed. The process is usually done to allow fish passage and keep the dam’s value as a monument to human ingenuity.  They have such amazing demolition tools these days. That hydraulic jackhammer and that claw & bucket are really impressive and innovative.

The amount of sediment in the riverbed may be too great for dredging to be effective,  Sediment may cover over 50% of the reservoir, causing a rise in surface water level in the reservoir.

Replacing the power produced at the dam would cost an average of $271 million per year, a number that is larger than the $217 million estimate of what it costs to keep the dams. Enter the HUG that can continue to power the dam!

HUG INNOVATION

HUG (Helical Unique Generation) is a New Good, an Innovative Hydro Electric Power System which has never been seen before; it substantially deviates from any other good or service produced before. Over the past decades, no major breakthroughs have occurred in the basic machinery of utilities.

GRAND IDEA

This “one inventive idea” is not like a grand idea similar to wind turbines, that started small and developed into 150,000 MW globally. Each new development of wind turbines was an improvement on what worked well in the first place. The grand idea of the wind turbine was something to work toward, but the grand idea had to come first.

Inventions whose ideas remain in the Box, which are only a slight change to present ideas have never succeeded in the last 30 years. Each country knows that it must find more sources of sustainable energy. The Department of Energy from each country turns to the engineering departments of universities — almost in desperation. Under extreme anxiety, the staff comes up with an idea, but the idea come from inside the Box. Often the government throws millions of dollars at that one inventive idea“.

The wave energy industry is in its infancy, with no commercial-scale facilities operating anywhere in the world. Bloomberg New Energy Finance, a London-based researcher, in August said the evolution of marine-energy systems is taking longer than expected and costing more than forecast. BNEF lowered its capacity forecast for wave power by 2020 to 21 megawatts, 72 percent less than its original estimate. It stated large amounts of money will be required for wave power to catch up with wind and solar. 

A theme among wave power experts is that wave energy is where wind energy was three decades ago. It will likely require the participation of some large companies, such as GE or Siemens.

Many wave energy inventions are unsatisfactory because they are huge and heavy and would require expensive regular maintenance. Many of these inventions have a lot of moving parts that can wear out in a harsh environment, especially in the agitated salt-water, which can do a lot of corrosive damage.

Pelamis Wave Power Ltd., a U.K. maker of  a very heavy wave energy system, was worth €8.2m for the initial pre-commercial phase. In September 2008, they were not able to raise the money needed to continue development despite years of work by a plethora of start-ups and many millions of dollars in government support. The cost was becoming too high related to  the small amount of energy produced.

Cost is the number one disadvantage of wave energy. The possibilities of the proper technology is so varied: many innovators grope for different solutions to this very high potential, and research can be directed aimlessly in many directions. This is the reason why some companies have gone out of business as their technology failed in actual field tests. These many approaches lead to speculation on innovation and the costs are high only because of the wrong initial path.  

In the absence of information on how projects operate in real-world conditions and how they affect the environment in which they operate, ocean energy developers cannot  attract capital because of low power density of many wave energy inventions.

Wave Energy is only a niche renewable energy technology. While other forms of alternative energy like solar, wind and biomass see hundreds of  billions of dollars in investment each year, wave energy does not see even $1 billion in investment globally.

The solution to finding the best wave energy solution has nothing to do with troubles to jump starting any new industry. You can’t start to develop word processing starting with a manual typewriter. The wave technology is so different that it requires an entirely new perspective. What is required is an idea that comes out of the Box. The jet engine was an idea that came out of the Box of all propeller-driven engines.

Something went Wrong!
