Hello, this is Konagaya, who is the representative of Rera Tech.
In Tohoku, where I visit on a business trip, the cold in the morning and evening is stronger, and it seems that winter visits are approaching as soon as possible (is it still early)?
The topic introduced this time is "About Australia's energy policy and wind power generation market".
The trends of wind power not only in Japan but also overseas have been reported, but I did not have the impression that I heard information about Australia while not studying. But recently, I think the opportunity to hear new news about Australia's offshore power has increased.
Therefore, we examined the potential of Australia to the wind power market and the current changes.
Unlike Japan, Australia is a country that is blessed with its own energy resources (fossil fuels, uranium, etc.). In particular, it is an exports of energy fuel such as coal and natural gas, and is the third country trade balance (-296mtoe) in the world as of 2021. (Figure 1)
By the way, Japan is + 357mtoe, the world's second import country.
Figure 1 Country trade balance of total energy in 2021 (Mtoe; Oil conversion ton)
In Australia, most of the energy consumption is covered by thermal power (92.0 % in 2020-2021), and renewable energy is only 8 %. Among them, renewable energy is composed of solar power generation, wind power, hydroelectric power generation, and biomass power generation. (Figure 2)

Australia has a vast land and ocean area and is considered to have a high potential of renewable energy, but in fact it seems that carbonization has not yet progressed.
In addition, he has been cautious about using nuclear power generation as a trump card for decalinationed in its own country. Since this was before the Japanese nuclear accident in 2011, it seems that the difference in stance to the nuclear power plant is very interesting if we overlap with the restart of the nuclear power plant discussed in Japan.
Another potential of Australia is the high wind speed.
High wind speed is one of the preferred conditions in wind power generation projects, but as shown in Fig. 3, the Australian wind is the condition of Japanese, even if the annual average Australian and Japan are simply compared to the annual wind speed between the planned waters. You can see that it is better. In addition, Australia has a vast sea area.

Recent trends in Australia
In 2022, the Australian government designated the bus strait strait off Victoria as the first offshore wind power development area. (Fig. 4) Maps showing the details of the sea area are also published to the general public, and public comments on development are currently required.

And in New Southwales, right next to Victoria, there is a movement related to offshore wind.
In 2022, Irawara Renewable Energy Zone (Rez) announced a power generation and power storage project. In the public comment, 44 interests were expressed, of which eight were offshore wind power plants.
I felt strongly that the state of the "green hydrogen" of renewable energy x hydrogen was emphasized by the fact that the state was attracting hydrogen manufacturing and hydrogen power generation projects.
Asia Pacific is considered the same area as Japan, but we believe that these various factors will attract more attention as a promising offshore wind market in the future. In fact, there have been a series of reports from Europe to enter the Australian offshore wind market.
On the other hand, there are reports that Japan is no longer a promising market for overseas windmill manufacturers due to stricter and prolonged necessary processes, and there is concern that the so -called Japanese market will be isolated.
I thought through this research that in order to grow in the offshore wind power generation market in Japan, it is urgent not only from a technical point of view but also from such a socio -economic perspective.
As a wind -up consultant, Relatech will conduct an optimal air -based survey using "observation" and "estimation" for wind power. Please feel free to contact us if you have any consultation on the style.
