Vertical Wind

Vertical Wind is developing a new kind of wind power technology with lower investment costs and significantly less maintenance. Vertical Wind’s simple, elegant turbine design and modern generator minimizes the number of moving parts to reduce the cost per installed capacity (kW), and, more importantly, the cost for converted energy (kWh).
 
In February 2010 the first Vertical Wind 200kW Vertical Axis Wind turbine was installed in Falkenberg, a small city on Sweden’s west coast with a big wind power investment. Falkenberg was early to try horizontal axis wind turbines in the 1990s and are pioneers in the use of vertical axis models.

Ultimately it is cost for converted energy that rules and Vertical Wind turbines have several advantages.
• They are simple and robust with few moving parts to simplify installation and maintenance and raise turbine efficiency.
• Generator maintenance is easy to provide at ground level.
• Power converted is governed electrically by the generator; this means the system can deliver power across a wide spectrum of varying conditions.
• Low blade speeds produce little noise, and the horizontal movement may provide less visual interference; together these factors should increase acceptance of wind power.
•Towers are made of a wood composite material saving enormous amounts of steel and energy in producing the turbine.

The potential for wind power development is huge; global wind energy resources amount to 600 exajoule (EJ), of which we today use 1 EJ. Global annual energy consumption is 490 EJ, with fossil fuels such as coal, natural gas, and oil delivering 80%, nuclear power 5%, and renewable energy 15%.

The US could produce 150% of its current power consumption using only wind power. In China, renewable energy is expected to supply 16% of the energy supply by 2020, compared to 7% in 2005. The contribution from wind power is expected to increase by 2,400% in this period. In Europe, where wind power capacity has increased five-fold since 1999, wind is also expected to grow rapidly in the coming years, not least due to the EU target of 20% renewable energy by 2020. Vertical Wind is developing more cost-efficient and robust solutions in wind power to accelerate expansion of wind power internationally.

A 200 kW Vertical Wind turbine with an estimated 20-year lifespan should yield 2,200 capacity hours per year, which could reduce carbon dioxide emissions compared to other energy generation by up to 8,800 tons during the course of its life. If the company sells 1,200 wind turbines per year (1.2% of the global market for new capacity), 24,000 wind turbines over the course of a life cycle could reduce emissions 10.6 million tons per year. Including larger wind turbines in the Vertical Wind line-up could accelerate these benefits over time.

Vertical Wind will develop, manufacture, and market complete wind power systems. Initially, production will be established in Sweden; should the venture prove successful, production will take place close to markets and consumers globally. The company recently installed its first 200 kW vertical turbine in the city of Falkenberg, Sweden, and Swedish E.ON has already ordered three more for testing.
 
While Vertical Wind will first concentrate on the Swedish wind market, the company plans to establish production in or near large international markets.

 

Vertical Wind AB  was founded in 2002 by researchers at the Division for Electricity and Lightning Research of Uppsala University. The company is headquartered in Uppsala, Sweden and has a production facility in Falkenberg. Björn Hellström is CEO.
