12 JunePenzhinskaya TPP
The answer to this question was given by Soviet engineers, back in 1972. There is a unique place in the Sea of Okhotsk - Shelikhov Bay. The minimum distance between the banks in the Penzhinskaya Bay area is 130 kilometers. The largest tidal wave in the Pacific Ocean is observed here - 14 meters. By building hydraulic structures with electric generators, you can get a huge amount of electricity, without environmental consequences for nature.
At that time, the Penzhinskaya TPP (tidal power plant) project was not in demand. There was enough electricity in the region, no one spoke about "green" electricity in general.
Today, a super-power plant in the Sea of Okhotsk is a "saving straw" for Russia. According to the calculations of the engineers of the Gidroproekt Institute, the capacity of the Penzhinskaya TPP may be more than 100 GW. (more than half of all electricity generated in the Russian Federation). For comparison, 22 GW - this is the capacity of the world's most powerful power plant "Three Gorges" on the Yangtze River in China.
Tidal electricity is absolutely clean. The prime cost of one MW is several times cheaper than that produced at the CHPP. The dam in the Penzhinskaya Bay will not have any impact on nature. The generated energy can be used to produce "green" hydrogen - a fuel for the future.
"Construction of the century" will cost "a pretty penny." The dam in the Penzhinskaya Bay, together with the power plant, is estimated at 4.5 trillion rubles. Russia spent a little less on the Olympic Games in Sochi.
According to the Minister of Finance Anton Siluanov, the National Welfare Fund (National Welfare Fund) currently has more than 13 trillion.
A hydrogen plant, a port for shipping products, and the corresponding infrastructure will also require considerable investments. But this is an economy, with a subsequent return on investment.
If Russia is destined to be a "gas station country" (and there is no other way in the policy of the state), it is necessary to take a leading position and think about tomorrow. There is money in the NWF. Today they are invested in various foreign currencies and do not work for the benefit of the Russian Federation. Maybe it makes sense to spend them on the development of promising technologies in order to be "ahead of the rest of the planet"?
