7,000 MW power can be generated from sea waves

Deal 'awarded' thru' AL leader's influence

. BSS, Dhaka

The country can produce as muchas 4,000 to 7,000 megawatts of electricity along 710 kilometres of coastlinefrom the waves of the Bay of Bengal, a preliminary study done in Cox's Bazarclaimed on Saturday.

Researchers of the two-year studysaid generation of electricity from sea waves was found to be the most feasibleone than any other available renewable energy options such as solar and wind interms of its cost and sustainability.

The option would, however, becostly initially than the conventional sources of electricity from fossil fuelsthat include gas, oil and coal in Bangladesh, a power hungry country thatrequires more and more electricity to accelerate its over the 6 per centeconomic growth and become a middle-income nation in next 10 years.

"It's a blessing. We did noteven think of such promising result that has shown us a new path of solutionsto power deficit in Bangladesh," Professor Dr Kamrul Alam Khan told BSS inthe city on Saturday..

Kamrul, a physics professor ofJagannath University and a co-author of the study, said sea wave power can begenerated at the onshore, near the shore and in the deep sea, but onshore powergeneration through LIMPET (land installed marine power energy transformer)would be realistic now as Bangladesh has a vast coastline ready.

The researcher said an estimatedTaka 75 crore is required to generate one megawatt of electricity through solarpanels, while it cost Taka 20 crore for the wind power. But the wave energygeneration for a megawatt would cost Taka 4 crore, a figure which is muchhigher than conventional methods of power generation.

Asked how he finds wave energygeneration feasible, Kamrul said initially the cost seemed to higher thantraditional ones, but it would come down in next decade as the global forceswere switching over to renewable energy options quickly.

"The more you use, the moreit would become cost-effective," he said reminding that wave energy wouldcost higher for the time being because it is an 'alternative' energy option.Any alterative would cost higher, he said and added that the world is likely toreplace fossil fuel and nuclear energy options by 2050.

Many European countries,including Germany, Denmark and Norway, are at the forefront to bank onrenewable energy sources, he said, suggesting the government to negotiate withsuch countries for technology transfer and investment in the sector.

When contacted Danish Ambassadorin Dhaka Svend Olling said Denmark has a deep interest in development of waveenergy generation in Bangladesh, a place where he sees wave as a most potentialsource of future energy.

He said the researchers inBangladesh and institutes in Denmark could have joint initiatives to spearheadthe cause, and find feasible and affordable solutions for power generationlocally.

Bangladesh Power DevelopmentBoard (BPDB) sources said nearly fifty percent of total population has nowaccess to electricity with an average present peak-hour generation of 5,200 MWevery day.

The loadshedding has come downsubstantially in last two years, but the country still needs nearly 1,000 MWmore to meet the present demand, which is soaring 10 percent every year.

More than 82 percent ofelectricity is now generated from gas-fired power stations, 7 percent fromdiesel, 6 percent from furnace oil, 2.5 percent from coal and close to 3percent from hydro. Solar power-as the lone clan energy option-is being used inthe off-grid areas, while a small wind power plant is still on a trial run.

A BPDB official said they havebeen closely watching the renewable energy development in Europe and wouldembark on it after major successes there. "We cannot afford expensive newtechnologies now, but definitely we will love to opt for renewable and clean energyin near future."
 
This is great news, Bangladesh should introduce new technologies like Norwegians, Swedes and other smaller european/scandinavian did in early 70s. Turn this sea water into gold, not only can this sea water be used to generate electricity but the sea water with technology can be cleansed and made available for usage and drinking, this is the future of clean pure water look at RSA and U.A.E.

As the enery is renewable, the cost of installing this will spread out over a period of time. So its good for us in the long run. I say we go ahead with this project.

One question though, will this disrupt the shiping lines? Cos our waters are quite shallow. Furthermore when we get our submarines, this thing may disrupt their routes

I think at this moment you should not look at the cost, if Bangladesh can get the complete transfer of technology and development in home starts in the future Bangladesh can export and help other regional nations that even includes Pakistan.
I believe putting yourself in debt to introduce cost effective reliable futuristic technology for cheap electricity providence, the debt is nothing compared.
 
Its quite expensive. A lot of countries would be on it by now if it wasn't the case.

Interesting video.

Don't look at the cost, the efficiently and reliability channel to get electricity for decades to come, cost is nothing compared like i said earlier, the sooner you get into this Area and develop, that nation could become the market for the future.
 
very good option most of the power shortage will be covered but i think it will take some years to come to reality in whole world.
