World outlook


10 The Energiewende storms ahead


For over a decade, Germany’s leaders have talked enthusiastically about boosting the country’s wind sector – but German turbines have traditionally struggled to get noticed. However, with the Russian invasion of Ukraine forcing a rethink of how the country secures its electricity – and a new green-friendly government ensconced in Berlin – could Germany finally fulfil its wind potential? Andrea Valentino talks to Christoph Podewils at Global Solutions Initiative, and Heike Winkler at WEB, to learn more.


Offshore


14 A growth experience As offshore wind turbines grow larger and larger, challenges arise over their installation. Nicholas Kenny hears from Martin Lysne, senior analyst for rigs and vessels at Rystad Energy, about the ramifications this could have for the industry and the work being done to address the issue.

4 Technology


22 As fast as the wind Floating offshore wind offers great potential over its fixed counterparts. However, current models have huge blades, which limits the amount of energy that can be produced. Andrew Barnett speaks with Wind Catching Systems CEO Ole Heggheim and vice president of industry and government affairs Daniel Engelhart-Willoch to hear about a platform which will contain over 100 rotors with 15m-long blades stacked vertically within a 300m-high frame. Due to their smaller size, they should be able to harness higher wind speeds, generating more energy at a cost that could compete with fossil fuels.


Onshore 25 Onshore assurance


The wind power industry faces supply chain issues and rapidly rising costs due to inflation across the board, but onshore wind has been hit the hardest. Abi Millar talks to Alessandro Mancino, head of onshore sales at Siemens Gamesa, Oliver Metcalfe, head of wind research at Bloomberg NEF, and Shashi Barla, an analyst at Wood Mackenzie, about the challenges facing onshore wind and why wind energy companies are still optimistic about its future.

Special report


30 Power up With many of the prime locations for wind turbines currently occupied by


older models, repowering could prove vital for the future growth of the industry. Elly Earls speaks to Ivan Komusanac, electrification advisor at WindEurope, to find out what the repowering process looks like at present and why it is crucial for governments to streamline permitting procedures.


HSE 34 Turn off the lights


Blinking red lights have been a night time staple of wind farms forever. And though the flashes are important for keeping turbines safe – not least to stop low-flying aircraft from crashing into them – local residents have long been frustrated with the light pollution wind farms can cause. But with the rise of so-called aircraft detection lighting systems, these challenges could soon be a thing of the past. Andrea Valentino hears from Jasper Salzwedel, senior sales manager at Deutsche Windtechnik, to learn more.


Operations & maintenance


37 Inspection gadgets Wind farm operators are using a combination of drones and AI to autonomously and semi-autonomously monitor wind turbines for damage or defects, offering faster, more accurate and safer methods of inspection. Nicholas Kenny speaks to Michael Corsar, chief technology officer at Innvotek, to learn more about what autonomous and semi-autonomous drones can offer the industry.


Events


41 Stalling at the green light The case for wind energy has never been stronger, argues WindEurope CEO Giles Dickson. However, the European wind industry needs to overcome supply chain challenges before it can deliver – clean, home-grown energy. WindEurope are the European Partner for WindEnergy Hamburg.
