Germany needs 70GW of offshore wind power connected to its grid by 2045, part of an estimated 300GW total capacity by 2050 for all of the nations bordering the North Sea. To achieve that ambitious goal it needs to run power cables through the Wadden Sea, the world’s largest system of intertidal sands and mudflats. The area is difficult to work within due to its dynamic environment, sensitive habitats, and bird nesting locations contributing to its World Heritage site status.

The North Sea itself is no picnic, and extensive surveys need to be carried out, and actioned, at a pace unthinkable without the use of cutting edge technology and clever programme management. Beyond the challenging offshore conditions, developers must navigate competing uses of sea, including shipping routes, military practice areas and other designated use areas. This work can be carried out throughout the year with special rigs, uncrewed surface vessels and remotely operated vehicles. The resulting data is collated and analysed through cloud-based platforms and advanced AI tools to provide the optimal routes for power cables. The routes are refined and optimised as new survey information becomes available and additional sea-use constraints are introduced by the government and the market.

In this episode Fugro, along with German grid operator TenneT, set out the challenges of working in the narrow German economic zone, as the industry races to meet these connection requirements ahead of a volatile geopolitical situation, and the hungry grid of Europe’s industrial powerhouse.

In October 2012, Hurricane Sandy turned sharply west and drove a storm surge into New York Harbor. Lower Manhattan flooded, a substation failed leaving more than 220,000 people without power, and damage across the wider region reached $65–70 billion.

Protecting the Lower East Side from the next storm means threading flood walls, berms and deployable gates through one of the densest parts of the city. Defences sit above generations of utilities: sewers, water mains, power and telecommunications infrastructure. Works also had to avoid separating communities, while ensuring access to city parks and the waterfront.

Engineering capacity is stretched by modern demands, and extreme weather poses increasing risks. Engineers need new approaches that enable them to evaluate and test more options, more quickly and effectively than ever before. Artificial intelligence, digital twins, and open data approaches provide the tools to do just that.

These technologies can reduce tasks such as floodgate analysis from 30 hours to just 30 minutes. Across the infrastructure lifecycle, digital advancements are boosting efficiency and improving outcomes, transforming once cost-prohibitive concepts into the resilient infrastructure systems that society depends on.

In this episode, we celebrate Showerkap, winner of the Innovation Champion category in the Engineering Matters Awards 2026. The final award of the series. Judged by representatives from the Institution of Mechanical Engineers and Engineers Without Borders UK, the award recognises innovation across all of this year’s categories.

Showerkap won gold for technology designed to reduce the water and energy wasted in showers. Its system uses sensors to monitor showers at fixture level, helping building operators understand water use and spot maintenance problems. Its patented valve technology can also encourage people to take shorter showers by gradually reducing the flow of water, rather than imposing a fixed limit.

We learn about how the technology works and the role small changes in behaviour could play in tackling water waste.

In this Engineering Matters Awards episode, we celebrate the winner of the Net Zero Champion category, which recognises projects, processes, and tools that make a real contribution to reducing carbon emissions. The highest awards were to be given to those entries that demonstrate significant impact or widespread scope, or that overcome a specific challenge.

Our gold-level award-winning entrant was Ceres Power for its solid oxide technology, which can generate electricity with high efficiency while avoiding the combustion and associated emissions of conventional power generation. We explore how Ceres’ technology could help meet rapidly growing electricity demand, including from data centres, while supporting the transition to a lower-carbon energy system.

Returning to the Moon is the next step, but staying there is the next leap. Abrasive and electrostatically-charged dust particles cling to every surface, and find their way into every mechanism, while a radiation-blasted lunar surface swings from 130°C in the sun to a brisk -173°C in the shade.

To survive and thrive in the lunar wasteland, we will need habitat modules, power plants, autonomous rovers, drilling equipment and more: a fleet of machinery that needs to survive these hostile conditions.

How we design these machines will be critical, how lubricants behave in extreme temperatures and hard vacuum is yet to be determined. But engineers are beginning to answer some of these questions.
