In a bid to reduce carbon emissions and contribute to the production of clean energy, several companies and heads of state are on the run to install renewable energy sources. Various areas may not meet the requirement to install wind turbines, solar panels and other technologies relating to various conditions.
Typically, countries that face regular storms or suffer from cyclonic conditions find it difficult to install wind turbines, a primary power generation tool. To combat such a situation, a Japanese startup, Challenergy, has designed and developed a wind turbine that harnesses the energy of typhoons.
Challenges and turn them into a source
In a country like Japan, where renewable energy is the fastest growing source of energy, most of it being powered by the sun, the government has started to promote wind energy, mainly through the offshore wind bias.
According to a report from World Economic Forum, Japan experiences an average of 26 tropical storms and typhoons per year. Additionally, climate experts have warned of more frequent and powerful cyclonic conditions in the country as the world goes through a phase of abrupt climate change.
In such unfavorable situations, wind power generation is difficult. Challenergy Founder Atsushi Shimizu said, “One of our goals is to turn typhoons into strength. The startup aims to take advantage of the vast energy brought by typhoons as they do not see it as a disaster but as a source of energy.
How would these turbines work?
Conventional wind turbines have propeller blades that are more vulnerable to cyclones and storms. With advancements in technology, the startup has brought the “Magnus Vertical Axis Wind Turbine”, which uses giant sweep revolutions for vertical squares that rotate on a horizontal axis in the direction of the wind.
The operational structure allows energy to be captured and makes the turbine design more robust. Such problem-solving innovations can solve the problems of various countries, including the Philippines, Taiwan, and China, as they face similar challenges.
