Infiltration energy: an abundant new clean resource from the river
After scientists develop effective systems for salt water power generation, the world's estuaries may soon be able to provide an abundant new clean resource, namely osmosis energy
.
Research published this week in the journal Nature outlines how much electricity
can be produced from a natural phenomenon.
This natural phenomenon occurs when fresh water comes into contact
with seawater through a diaphragm.
The osmotic process can be used to trap the charge of salt ions passing through the diaphragm to balance the concentration
of the two liquids.
"First we need to make the diaphragm, and then we need to study the optimal size of
the nanopores.
" Jiandong Feng, a researcher at the Laboratory of Nanobiology at the Ecole Polytechnique Fédérale de Lausanne in Switzerland and lead author of the study, said, "If the nanopores are too large, negative ions will pass through the thin film, and the resulting voltage will be too low
.
If the nanopores are too small, there are not enough ions passing through the diaphragm and the current will be weak
.
”
Infiltration energy is seen as a promising source of renewable energy, with the potential to be deployed in estuaries
where river freshwater meets marine salt water.
Unlike solar panels, which require plenty of sunlight, wind turbines require a lot of wind power, and osmotic energy can generate electricity
at any time of the day.
Pilot projects harnessing permeable energy have been carried out in Europe, Japan and the United States, mainly using fragile diaphragms to deliver small amounts of electricity
.
The potential for the new power generation system is so great that the researchers calculated that a 1 square meter diaphragm could produce enough electricity
to supply 50,000 standard energy-efficient light bulbs.
Before osmotic energy technology can be applied on a large scale, scientists need to find ways to
make relatively uniform nanopores.
