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.

 Energy from wave energy, tides, the oceans and hot hydrogen fusion are other forms that can be used to generate electricity. These energy sources are often non-centralized, leading to greater consumer control and involvement.

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.

WORLD ENERGY

By 2040, world energy demand is expected to dramatically increase (in 25 years)

Worldwide energy usage is on track to increase by roughly 40% in the next 20 years and to nearly double by 2050. Carbon emissions still have to be cut 84% by 2050, yet almost 70% of the kilowatt-hours of electricity consumed today comes from coal or natural gas. Electricity has to be the dominant energy form used in the future.

The allure is irresistible. A wave energy system that could harness an inexhaustible, nonpolluting source of energy and be deployed economically in sufficient numbers to generate significant amounts of electricity—that would be a feat for the ages.

The Burning Question

The Burning Question Answered

Climate change is the most difficult problem the world has ever faced: it is huge in its global scope and  they are the biggest challenge of the century. We have far more oil, coal and gas than we can safely burn. We can only avoid devastating damage if most of the world’s coal, oil and gas are left in the ground. We can’t burn them if we care about climate change. Is this the Burning Question?

Here is the problem:  even if we gave up on all the obscure and unconventional fossil fuel resources that companies are spending billions trying to access and just burned the “proven” oil, coal and gas reserves – the ones that are already economically viable – we would emit almost 3 tons of carbon dioxide. No one can say exactly how much warming that would cause, but it is overwhelmingly likely that we would shoot well past 2 C degree and towards 3 C degree or even 4 C degree of warming.

The Burning Question

The book, Burning Question reveals climate change to be the most fascinating scientific, political and social puzzle in history. It shows that carbon emissions are still accelerating upwards, following an exponential curve that goes back centuries.

The simple truth is that tackling global warming will mean persuading the world to abandon oil, coal and gas. For all the uncertainty about the detail, every science academy in the world accepts the mainstream view of man-made global warming. Continue reading The Burning Question

Secret: Low Cost Wave Energy

 Low Cost  Energy

The secret to low energy costs is to keep the Breakwater cost low:  build a road-worthy seawall from the shore so that trucks can haul stone works more economically than by barge.

Building a Breakwater from the Shore

Wave Energy Breakwater
Breakwater

A major part of the breakwaters constructed in the world are the so-called conventional ruble mound breakwaters, which consist of a core, a filter layer and a heavy armor layer. An alternative to the conventional ruble mound breakwater is a berm breakwater. 

When there is a rock quarry, relatively close to the construction site, which is dedicated to the breakwater project, the Icelandic type has proven to be very attractive economically. The basic reason for that is that unlike the other types the Icelandic type utilizes the quarry 100%.

The smaller armor stones are then placed rather deep where the influence of the wave attack is less, as well as on the rear end of the structure, while the largest stones are placed where the largest wave attack is expected. 

 The key to the use of the Icelandic berm breakwater design is in its ability to match the predicted quarry yields of the potential quarries.

The equipment park used by the contractor consists of 4 backhoe excavators 110, 75, 50 and 25 tons, three front loaders 75 and two 45 tons, three dumpers, a split barge of 250 m3 capacity and three drilling rigs. They used a large excavator both in sorting the largest stones and placing them on the breakwater.
