With climate change becoming a greater concern, there has been a greater emphasis on renewable energy sources and the desire for clean energy. This has resulted in the fast development of novel energy-harvesting methods, such as tidal power.
Tidal power is a type of hydropower with enormous potential to power our future.
In this post, we’ll look at some of the most essential benefits and drawbacks of tidal energy, as well as what we may expect from this sustainable energy source.
What Is Tidal Power?
The first thing that comes to mind when you think about tidal power is undoubtedly tides, and you’d be right! Tidal power, also known as tidal energy, is the gravitational impact of the moon and sun on the water. Low and high tides from coastal locations can generate currents powerful enough to power turbines. These turbines provide useful kinds of energy, such as electricity.
The Pros And Cons Of Tidal Power
The pros of tidal power.
1. It is renewable.
Tidal energy is a renewable energy source, which implies that it does not diminish as it is consumed.
So, by harvesting energy from shifting tides, you are not reducing the amount of energy that the tides may create in the future. The gravitational pull of the sun and moon, which governs the tides, is not going away anytime soon.
2. There are no carbon emissions.
Tidal power plants, in addition to being a sustainable energy source, do not release greenhouse gases during electricity generation.
Finding zero-emission energy sources is more crucial than ever since greenhouse gas emissions are one of the primary drivers of climate change.
3. Consistent
The tidal currents are quite predictable. Low and high tides follow predictable patterns, making it easy to predict when electricity will be generated throughout the day.
It also makes it simple to predict how much power will be generated by turbines since the force of tides and currents can be properly projected.
4. Powerful output
Tidal power facilities may generate large quantities of electricity. One of the primary reasons for this is that water is extremely dense – over 800 times denser than air.
This means that a tidal turbine will generate far more energy than a wind turbine of comparable size.
Furthermore, even at modest speeds, the density of water allows it to power a turbine. As a result, even if the water conditions aren’t optimum, tidal turbines have the ability to generate enormous amounts of power.
The cons of tidal power
Unfortunately, while everything appears to be well with this renewable source of energy right away, there are several severe concerns related with its use:
1. Environmental impact
While tidal power does not contribute to emissions, each plant has a significant environmental impact. Stream generators, for example, can affect aquatic life, and marine species, in particular, is extraordinarily specialized in its adaptations, implying that initiatives like as DTP have an unknown, large-scale impact.
2. Expensive to construct
Expensive to build-Tidal power plants are enormous projects with extremely high upfront expenditures.
3. Short power generation
While dependable, tidal electricity can only be used for a limited period of time during the day. While dynamic tidal power plants avoid this, they are still in their infancy.
4. Limited locations
Tidal power can only be generated in a limited number of sites. Furthermore, considerable infrastructure development is required in order for electricity to be harnessed to the grid at large in most nations.
5. Maintenance is difficult
Maintenance is tough-By definition, these plants are difficult to maintain. Any apparatus, no matter how well constructed, will always require maintenance, and there are some severe issues connected with sustaining this level of power.
Is There A Future For Tidal Power?
Tidal power has now seen some limited real-world use, and while tidal stream generators are the most “mature” of the technologies, no meaningful standard has yet been created. The largest generator currently in operation is South Korea’s Sihwa Lake Tidal Power Station, which produces just 254MW of energy.
There are other ideas for greater capacity stations, but only the United Kingdom is actively developing tidal power plants of any significant magnitude.
Even when seen as a minor part of a bigger solution, the problems of tidal power appear to outweigh the benefits.To be honest, solar and wind energy continue to outperform hydropower in the realm of renewable energy, and all of these types of energy have considerably less drawbacks than tidal energy generation.
In most situations, the influence on the maritime environment is arguably the most serious worry. Large-scale plants have the potential to impair sea vistas and limit human use of near-coastal waterways, which are frequently utilized for pleasure.
All of this points to a bleak future for this supposedly limitless energy source, and it may reduce tidal energy to the status of a last resort in the future.
However, the technology is still rather young, and it may be prone to greater change than any other green source of energy save nuclear energy.
DTP plants, on the other hand, have enormous power production potential, and some businesses have begun investigating tidal arrays, which are constructed on the sea floor a long way from shore and then channel power back.
