Overcoming supply chain issues with renewables.

Europe is breaking free from fossil fuels by turning towards renewable energy, but obstacles in the wind industry’s supply chain could prevent this, especially those that affect the availability and prices of raw materials, like steel, which are essential to manufacturing large wind turbines. Here, Karthik Velayutham, Chief Technology Officer (CTO) of Greentech innovator Katrick Technologies, explains how its new Wind Panel technology, which sidesteps the common issues traditional wind turbines, could hold the answer.

According to a report by the Financial Times, inflation and the ramifications of the Ukraine war have resulted in price hikes for energy and crucial raw materials such as steel. Consequently, this will lead to an escalation in the costs of turbine manufacturing. Meanwhile, McKinsey and Company cite fluctuations in the supply and prices of raw materials and frequent changes in regulations as reasons behind the high volatility in the renewables markets.

Raw materials, such as steel, fibreglass, and composites, are used in the manufacturing of rotary parts in large wind turbines. Steel is commonly employed for the main shaft and structural components, while fibreglass and composites are utilised to produce rotor blades. These raw materials undergo processes such as shaping, moulding, and bonding to create the robust and aerodynamic rotary parts that are essential for the efficient operation of wind turbines.

High prices and uncertainty in the supply chain are a growing concern for the wind industry — especially as projects, including supplier and manufacturer arrangements, are often planned, and bid for several years before development.

Industries must look to new technologies to harness wind power. But, before they do this, it is crucial to address the broader supply chain issues affecting the renewable energy industry.

Addressing the issues

The renewable industry should diversify its supply sources: relying on a single supplier or geographic region for critical components can create vulnerabilities. Diversifying the supply base and exploring partnerships with multiple suppliers can mitigate the risks associated with supply chain disruptions.

Improved information sharing and collaboration across the supply chain can help to identify potential bottlenecks and mitigate disruptions proactively. This means establishing clear communication channels and fostering close relationships between project developers, manufacturers, and logistics providers for more efficient operations.

This brings us, next, to new innovations and technological advancements. Continued investment in research and development is essential to drive innovation and address supply chain challenges. Governments and industry leaders should collaborate to foster a supportive environment for technological advancements that enhance the efficiency and reliability of renewable energy systems.

Fortunately, one such innovation — a new Wind Panel system from Katrick Technologies —can improve how businesses harness wind power.

No rotary parts

Katrick Technologies' Wind Panel technology offers a unique approach to address the issues of raw material supply in relation to large wind turbines. Unlike traditional wind turbines, the Wind Panel does not rely on rotary parts.

Instead, it consists of numerous channelling ducts with patented aerofoils. These aerofoils convert low-level wind energy into mechanical oscillations, which are converted into electricity. The Wind Panels can be installed in various environments, including urban areas, where the installation of traditional turbines is not feasible.

By having no rotary parts, Katrick Technologies' Wind Panel also bypasses some of the common issues associated with rotary parts in large wind turbines, such as fatigue and mechanical stress, potentially causing cracks, deformations, or failures; and the consequent need for time-consuming and costly maintenance and repairs requiring specialised equipment and expertise.

In addition, Katrick’s Wind Panels collect energy in small pockets, allowing their solution to capture turbulent ground-level winds. This maximises the amount of kinetic energy captured while addressing the limitations of traditional turbines. The aerofoils oscillate independently as wind passes through them, creating pockets of energy that can then be converted into sustainable electricity.

Katrick estimates that, if installed along a one-kilometre stretch of road, the panels would generate enough electricity to charge 80,000 Tesla electric vehicles or power 760 homes.

Driving progress

While the Wind Panel system offers a promising solution, it is crucial to address the broader supply chain issues affecting the renewable energy industry. Collaboration between governments, industry stakeholders, and technology innovators is paramount in driving progress.

Long-term planning and policy stability are also needed, including a stable policy framework and long-term visibility can instil confidence in the renewable energy sector. Governments should establish clear renewable energy targets, promote favourable regulatory environments, and ensure consistent support for the industry's growth.

By implementing these strategies and embracing innovative solutions like Katrick’s Wind Panel technology, the renewable energy industry can overcome supply chain issues and thrive. With a robust and resilient supply chain, the industry can accelerate the transition to clean energy, reduce carbon emissions, and create a sustainable future.

The potential of renewables is immense, but to realise this potential, we must address the challenges within the industry head-on. By fostering collaboration, embracing innovation, and implementing effective strategies, we can overcome supply chain issues and ensure the continued growth of renewable energy.

It is not only a matter of environmental responsibility but also an opportunity to create a more sustainable and prosperous future — one that no longer relies on previous supplies of fossil fuels. Fortunately, with its scalability, flexibility, and ability to capture energy from different wind speeds and turbulence Katrick's Wind Panel technology presents a promising solution for wind energy generation.
