About Tidal Energy

In literature, the tide is the irreplaceable symbol of renewal since it functions in a back & forth cycle; Therefore, as the tide changes, we must change too. Today, time is not on our side; Each moment we lose is equal to become more unsustainable & more vulnerable to further environmental hazards.

Tidal energy is one of the most important renewable energy sources which are based on sustainability and constant reliability, starting costs are now high but since they are operable 24/7 they can gain their own money after a short period, although till 2020 the initial costs were high after the 2030 agenda & 2015’s Paris agreement demands for the renewable energy technologies had increased which resulted in mass production & obvious lower-front cost; Therefor, this system is better to be considered as a great solution since the comparison of same size blade turbines in both wind & tidal systems has shown an eternal winner, tidal.

Glorinda believes a constant investment would be the one that is more reliable even if the initial costs were high; Therefore, we won’t miss our chances on new high-tech systems such as tidal energy.

“The time of Renewal has come with tides”

Tidal energy is divided into 4 methods of harnessing:

1. Tidal Streams

The main method is tidal streams which means to put the turbines in front of the water stream; Water is denser than air, so when we put a turbine in front of this denser fluid will obtain more energy production than the same turbine which works with air as its fluid. Tidal streams are although based on fast-flow fluids but the blades are rotating slowly so they won’t be considered as harmful for marine lives; The whole system is more effective in shallow water.

2. Barrages

This method is based on dam function, long dam (called barrage) will be built across a tidal river or a bay or an estuary, since the dam is low-height (only as high as the highest height of local tide), water can spill over or through the turbine. The function is similar to a dam that harnesses river power, the barrage gates will open when the tide rises; At high tides, barrage gates are closed to create a pool or tidal lagoon, in this case when the gates are open faster flow will spill over the turbines.

3. Tidal Lagoons

Tidal lagoons are much like barrages but with a big difference they can be easily constructed on natural coastlines & not across the tidal river or bay or estuaries; Therefore, they can be easily considered as good storage for freshwater too, since they are not built across the river, they won't disrupt the marine lives either & their environmental impact is much lower than tidal streams turbines or barrage method.

4. Floating tidal turbines

This kind of turbine are new & the most well-known commercial one is the orbital O2 floating turbine that is installed on Orkney islands north east Scotland, this turbine is capable of producing the clean energy needed for 2000 homes.

Glorinda believes a constant investment would be the one that is more reliable even if the initial costs were high; Therefore, we won’t miss our chances on new high-tech systems such as tidal energy.
