Tap potential of generating power from sea waves: Expert

DHAKA, Oct 28 (BSS) – The country could meet its demand for electricity to a large extent by utilising the untapped potential of generating 7,000 megawatts energy from tidal and sea waves, an oceanographer said here today.

“Bangladesh has 710 nautical mile coastal lines which could be used for generating 700 megawatts electricity from tidal and waves,” said Abdul Matin Mondal, a governing body member of National Oceanographic and Maritime Institute (NOAMI), told BSS.

Mondal said an estimated Taka 75 crore is needed to generate one megawatt electricity through solar panels, while it costs only Taka 4 crore for the wave energy generation.

Referring to a feasibility study of a project styled ‘Tidal and Wave Power Generation (TWPG)’, he said three coastal areas — Sandwip of Satar Khal, Mongla at Pussur River and Baghkhali River at Cox’s Bazar — have been selected for tidal and wave power generation.

These areas were found to be suitable for extracting electricity as tidal ranges during spring tides vary from 4 m to 6 m, required for tidal power generation, he added.

“I think similar behaviour tidal pattern of other places of the country’s south and south east coast waters would also be viable for electricity production,” he added.

The tidal analyst said the project titled ‘Electricity Generation from Sea Wave (EGSW)’ is being implemented under NOAMI with the financial support from the Ministry of Science and ICT.

He said NOAMI, a professional scientific organisation deals with ocean science, has arranged a workshop early this week at Bangladesh Atomic Energy Commission (BAEC) to share key findings of the study.

Referring to the keynote paper presented in the workshop, Mondal said the NOAMI has of late generated electricity on wave basis at Kalatoli point of Cox’s Bazar where six bulbs (AC) and as many ceiling fans were operated from the sea wave.

“Denmark has a deep interest in development of wave energy generation in Bangladesh, a place where I sees wave as a most potential source of future energy,” he quoted Danish Ambassador in Dhaka Svend Olling as saying in the workshop.

NOAMI is planning to operate small electricity- run vehicles and charge mobile phone through sea wave, Mondal said insisting on the government to start power production through sea wave using the technology with involvement of private sector.

Experts see green future for Bangladesh through renewable power generation and the country should look seriously for energy solutions like solar, wind and sea wave beyond the conventional sources.
