Carbon emmision from solar boat is zero which would save environment
Zahid Hossain Biplob: The introduction of solar boat boardly would ensure standard and eco-friendly journey in waterways.
The government had set a plan to produce 10 percent or 2000 MW energy from renewable energy sources by 2020. As part of this plan, the government is going to introduce the solar boat services across the country for carrying passengers in the waterways.
Already, the government adopted a plan to introduce solar-powered passenger boats on the waterways to check water pollution as well as to ensure safe journey of the local people.
In generally, the engine-run small boats are traditionally providing passenger service in waterways which is not adequate against the demand, said the sources.
These small boats are being used for carrying passengers on short-length waterways in the country. After the implementation of the service broadluy, it would be able to provide hassle-free and standard journey for the people.
Instead of the engine-run boats, we are considering how solar boats could be introduced to save energy and environment,” said Dr Tabibur Rahman, project manager of ‘Sustainable & Renewable Energy Power Generation Project’ under Sustainable & Renewable Energy Development Authority (SREDA).
He said we have already built five conventional solar-powered boats of which one is plying in Hatirjheel and four in Foy’s Lake of Chattrogram on an experimental basis. “ Now we are trying to build fiber-glass based boats with solar panels, the boats will be sustainable,” he added.
But, Rahman said, entrepreneurs must come forward to produce fiber-glass boats commercially to make those cost effective for boatmen. For being sustainable, the demand for fiber-glass boats will go up, he added.
“We’ve already held a meeting with a Chattogram-based French agency to know about the cost of fiber-glass boats. We are also communicating with some other firms, which produce fiber-glass boats,” he said, adding that if fiber-glass boats could be produced commercially, its production cost will come down, which will be cost-effective for boatmen in carry passengers.Siddique Zobair, a member of Sustainable & Renewable Energy Development Authority (SREDA) told Daily Industry.
According to official statistics, the country has 24,140 kilometres of waterway comprising about 800 rivers and their branches. Wood-made boats are commonly used there. Nowadays, diesel-powered boats are mostly used for transportation with the adjacent villages of rivers and for fishing purpose.
The engine-run boat is fuel-inefficient and the majority of these boats depend on imported diesel resulting in a comparatively high operation and maintenance cost. Besides, diesel-run boats cause harm to environment discharging oil and chemical substances into river water. The diesel engine also produces enormous sound.
Considering the adverse impacts of engine-boats on environment, SREDA with the assistance of UNDP Bangladesh has produced five solar energy-based boats, which are readily operational in Hatirjeel lake in the capital Dhaka, Panam Lake in Narayanganj and Fay’s Lake in Chattogram on a pilot basis. Dr Md Taibur Rahman, project manager of Sustainable Renewable Power Generation Project of UNDP Bangladesh, said the limit of carbon outflow from solar boat is zero and that is why solar boats are suitable for water routes as it will not only contribute to saving money, but also saving environment.
About the environmental benefits of the solar boats, he said the use of about 6.67 liters of diesel worth Tk 494 will be decreased daily by a solar-powered boat while each solar boat will reduce 5.89 tonnes of annual carbon dioxide outflow. “Solar boat is hundred percent environment-friendly and free from greenhouse gas emission,” he added. Taibur said once the fiber-based solar boats are produced commercially, the cost of a boat will be about Tk 3 to 4 lakh, which will be affordable for boatmen.
Considering the environmental benefits of the solar boats, Siddique Zobair said, incentives should be given to producing fiber-glass based boats. “But, we must know how much incentive would be given. Our target is the introduction of the solar boat on river routes to to save energy,” he added.
