## At a glance

- Osmotic power generates electricity continuously using the pressure from mixing freshwater and saltwater.
- Japan's Fukuoka plant successfully produces reliable, uninterrupted power.
- Bangladesh's riverine geography offers ideal conditions for osmotic power implementation.

Yes, it is certainly possible. Bangladesh, a riverine country, has the ideal conditions for osmotic power generation. With hundreds of rivers merging into the Bay of Bengal, the fundamental requirement for osmotic power—the meeting point of freshwater and saltwater—is abundantly available.

## How Osmotic Power Works

Osmotic power, also known as blue energy, harnesses the natural pressure created when freshwater and saltwater mix at river mouths. This pressure is used to spin turbines, generating electricity continuously, unaffected by weather conditions.

## Japan's Success Story

Japan has successfully implemented osmotic power in Fukuoka, producing enough electricity to power 220 to 300 households annually. This plant operates 24/7, demonstrating the technology's reliability and potential.

## Challenges and Solutions

Despite its promise, osmotic power faces technical challenges, primarily efficiency. Advanced membrane technology and energy-saving pumps have significantly improved its feasibility. Japan leads in desalination membrane technology, controlling about 60% of the global market.

## Global Interest and Future Prospects

Several countries, including Norway, South Korea, Spain, and Qatar, are exploring osmotic power. Australia is also investigating its potential using saltwater lakes. Experts believe that with technological advancements, osmotic power could meet up to 15% of global electricity demand by 2050.

## Bangladesh's Opportunity

Given its extensive river network, Bangladesh has the potential to adopt osmotic power. This technology could provide a reliable, renewable energy source, reducing dependence on fossil fuels and intermittent renewable sources like solar and wind.
