A new onshore turbine for quieter wind power

By Zarkon Group,

Spotted: Wind manufacturing world leader Nordex Group has installed its first turbine in the 6-megawatt class at an onshore wind project in the Netherlands. Among other benefits, the new model is much quieter than its predecessors – reducing the impact on the local area.

The turbine—known as the N163/6.X—was launched in September 2021 as the latest upgrade from Nordex‘s Delta4000 series. Compared to its sister model in the 5-megawatt class, it is able to produce an up to 7 per cent higher annual energy yield thanks to its much higher rated output. Thanks to its flexible configuration, it can be adapted to the specific conditions at each project site, resulting in a tailor-made solution for each client. The design’s lifetime is 25 years, with an extended 35-year lifetime available for specific sites.

Nordex has installed a total wind power capacity of more than 32 gigwatts in over 40 worldwide markets since it was founded in 1985. Among its hosts are Germany, Spain, Brazil, India, Mexico, and the United States.

José Luis Blanco, CEO Nordex Group explains that, “Our turbines in the Delta4000 series are based on a standard technical platform. Consistent modularisation means that type-specific components, such as rotor blades or gearboxes, can be adapted for different variants. The N163/6.X is yet another example of how highly efficient solutions that have proved successful in practice can be specifically implemented for special geographic regions.”

Nordex installed its first N163/6.X in May 2022, and it’s expected that the model will be one of the most popular turbines on the market due to its low noise pollution levels.

The amount of wind energy generated worldwide grew by 17 per cent between 2020 and 2021. Recent wind power innovations spotted by Springwise include a wooden wind turbine that stores carbon, a sensor that monitors the strength and efficiency of wind turbine blades, and a two-bladed floating turbine that can handle almost any weather condition.

A power system brings reliable, affordable electricity to off-grid communities across Africa

A power system brings reliable, affordable electricity to off-grid communities across Africa

By Zarkon Group,

Spotted: In sub-Saharan Africa, the electrification gap is one of the primary barriers to development. As many as 600 million people in the region live without reliable power. Many basic needs, from education and healthcare to economic opportunity, remain out of reach for millions of people as a result.

Zola Electric, a company originally founded in Tanzania, has developed a power system that promises to bring reliable, affordable electricity to off-grid communities across Africa.

The Zola ‘Infinity’ system is designed to be more reliable and cost-effective than traditional grid-based power and can be quickly deployed to rural areas where electrification is most needed.

The system draws on multiple energy inputs and a smart storage system to provide continuous power. With Infinity, African families will finally have access to the lights, refrigeration, pumps, and other appliances that they need to improve their quality of life. Importantly, Infinity is also designed to be scalable and adaptable, meaning that it can grow with communities as their needs change.

Zola has received backing from a number of prestigious investors including Tesla, Total, and EDF.

Mini-grids and smart storage solutions will be increasingly important as the world’s energy system becomes more decentralised. Springwise has recently spotted a software service that optimises decentralised energy projects and a plug-and-play solar energy system for swarm electrification.

China to use robots to 3D print the second-largest hydroelectric power station in Asia

China to use robots to 3D print the second-largest hydroelectric power station in Asia

By Zarkon Group,

Spotted: China recently announced the construction of a massive dam on the Yellow River in Qinghai Province. The hydroelectric power station will be the second-largest in Asia. At 390-feet tall, the dam will be similar in height to the Three Gorges Dam (594 feet tall) – which is currently the biggest hydroelectric power plant in the world.

As the world moves to stop burning fossil fuels, two of the most popular renewable energy sources are solar and wind. Despite solar and wind power getting most of the attention, hydropower is more efficient and has a higher output capacity. In such a spirit, China’s Yellow River dam will show that hydropower is still a viable option for generating large amounts of renewable electricity.

Construction of the Yangqu Dam is well underway, and plans are for it to be built entirely by robots, without any human labour. The use of artificial intelligence (AI) and robots for construction is not only faster and more efficient – it also eliminates the need for human labour, which can be expensive and dangerous. In the case of the Yangqu Dam, using robots will also help to ensure that the dam is built to exact specifications.

In 2024, the first section of the Yangqu Dam will become operational. The entire project is expected to be completed the following year. Once complete, the dam is predicted to generate almost five billion kilowatt-hours of electricity per year, according to the South China Morning Post. That’s half a billion more than Arizona’s Hoover Dam – which is 726 feet tall and took 5 years to build. Ninety-six people also died during construction of the Hoover Dam. It is hoped that with 3D modelling and robotics, Yangqu Dam will be built without such risks.  

Other construction innovations involving robots recently spotted by Springwise include autonomous robots that reduce construction errors at the start of projects, a carbon-negative construction company that uses robotic builders, and the world’s largest 3D-printed building constructed by a robotic construction company.
