Danish wind giant Ørsted has completed three huge artificial nests designed to house a vulnerable seabird species near the UK’s Hornsea 3 offshore wind farm.
Hornsea 3 is a 2.85-gigawatt offshore wind farm that will be located off England’s east coast, around 120 km (75 miles) from Norfolk and 160 km (99 miles) from Yorkshire. It’s expected to be completed by 2025, and it will be capable of powering over 3 million households.
It’s also the first UK offshore wind project to require ecological compensation.
In order to gain consent for Hornsea 3, Ørsted was required to accommodate the Black-legged kittiwake (Rissa tridactyla), a vulnerable seabird species that could potentially be affected by Hornsea 3.
Food shortages and climate change are the most likely factors contributing to the downward trends in kittiwake numbers that have been recorded since 2000.
Kittiwakes aren’t your typical gull: They’re small and gentle and feed only on marine fish and small crustaceans. They don’t eat food out of garbage cans and swoop on people to steal food right out of their hands.
Eleni Antoniou, environmental manager at Ørsted, said:
Kittiwake are listed as at risk from extinction and with climate change as a key driver to their decline, a move towards a green energy system could help considerably in the long-term conservation of the species. In the meantime, the provision of these structures will provide a safe, nesting space to enable future generations to raise young away from predators and out of town centers.
Ørsted worked with UK marine contractor Red7Marine to build the giant kittiwake nests, which it calls “nearshore artificial nesting structures (ANS).”
The artificial nests are located off the coast of Suffolk, which is south of Norfolk, because it’s one of the most likely places for the artificial nests to be colonized quickly. Despite a lack of natural nesting sites – that is, cliffs – in Suffolk, kittiwakes have colonized the area anyway, and its population is growing there.
The giant bird nests, which were designed by a team of ecologists, architects, and engineers, are located about 1 km (0.6 miles) offshore. The structure is supported above the water on a single monopile. The octagonal topside contains a space with a table, chairs, and whiteboard so researchers can record data findings. Two cameras have been installed on each structure.
Each artificial nest has the capacity for around 500 nesting spaces spread across eight rows of ledges per nesting face. Individual nesting spaces are fitted with a sliding Perspex panel that allows researchers to view the kittiwake from inside without the birds seeing them.
The [nests] have narrow ledges and vertical sides to replicate the cliffs where kittiwake would naturally nest. There are eight sides to give kittiwake different options in case one side is too sunny or too windy. The main structure is off-white to blend in with the sky and sea.
Ørsted is going to monitor the birds for the lifetime of the ANS.

Following approval from Transport Canada, EV startup Workhorse will be bringing the W56 and W750 model electric delivery vans to commercial truck dealers in Canada as early as this spring.
“This is a major step forward for Workhorse,” says Josh Anderson, Workhorse’s chief technology officer in a press statement. “Pre-clearance from Transport Canada opens up a large new market for our products throughout Canada, including with fleets that operate across borders in North America.”
Despite that uncertainty, Workhorse execs remain upbeat. “We’re excited that our electric step vans can now reach Canadian roads and highways, providing reliable, zero-emission solutions that customers can depend on,” added Anderson.
Canadian pricing has yet to be announced.
Electrek’s Take

There’s no other way to say it: the Trump/Musk co-presidency is disrupting a lot of companies’ plans – and that’s especially true across North American borders. But in all this chaos and turmoil there undoubtedly lies opportunity, and it will be interesting to see who ends up on top.
The new Liebherr S1 Vision 140-ton hauler is unlike any heavy haul truck currently on the market – primarily because the giant, self-propelled, single-axle autonomous bucket doesn’t look anything like any truck you’ve ever seen.
Liebherr says its latest heavy equipment concept was born from a desire to rethink truck design with a focus only on core functions. The resulting S1 Vision is primarily just a single axle with two powerful electric motors sending power to a pair of massive airless tires designed carry loads up to 131 tonnes (just over 140 tons).
The design enables rapid maintenance, as important components easily accessible for quick servicing. Wear parts can be replaced efficiently, and the electric drive significantly reduces maintenance work. This helps to minimise downtimes and increases operational efficiency.
LIEBHERR
Because of its versatility, durability, and ability to perform zero-turn maneuvers that other equipment simply can’t, the Liebherr S1 Vision can be adapted for various applications, including earthmoving, mining, and even agriculture. There’s also a nonzero chance of this technology finding applications supporting other on-site equipment through charging or fuel delivery.
The S1 accomplishes that trick safely with the help of an automatic load leveling system that ensures maximum stability, even on bumpy or rough terrain. The company says this technology significantly reduces the risk of tipping while providing smooth and secure operation across various environments.
The HD arm of Hyundai has just released the first official images of the new, battery-electric HX19e mini excavator – the first ever production electric excavator from the global South Korean manufacturer.
The HX19e will be the first all-electric asset to enter series production at Hyundai Construction Equipment, with manufacturing set to begin this April.
The new HX19e will be offered with either a 32 kWh or 40 kWh li-ion battery pack – which, according to Hyundai, is nearly double the capacity offered by its nearest competitor (pretty sure that’s not correct –Ed.). The 40kWh battery allows for up to 6 hours and 40 minutes of continuous operation between charges, with a break time top-up on delivering full shift usability.
Those batteries send power to a 13 kW (17.5 hp) electric motor that drives an open-center hydraulic system. Hyundai claims the system delivers job site performance that is at least equal to, if not better than, that of its diesel-powered HX19A mini excavator.

To that end, the Hyundai XH19e offers the same 16 kN bucket breakout force and a slightly higher 9.4 kN (just over 2100 lb-ft) dipper arm breakout force. The maximum digging depth is 7.6 feet, and the maximum digging reach is 12.9 feet. Hyundai will offer the new electric excavator with just four selectable options:
enclosed cab vs. open canopy
32 or 40 kWh battery capacity
All HX19es will ship with a high standard specification that includes safety valves on the main boom, dipper arm, and dozer blade hydraulic cylinders, as well as two-way auxiliary hydraulic piping allows the machine to be used with a range of commercially available implements. The hydraulics needed to operate a quick coupler, LED booms lights, rotating beacons, an MP3 radio with USB connectivity, and an operator’s seat with mechanical suspension are also standard.

The ability to operate indoors, underground, or in environments like zoos and hospitals were keeping noise levels down is of critical importance to the success of an operation makes electric equipment assets like these coming from Hyundai a must-have for fleet operators and construction crews that hope to remain competitive in the face of ever-increasing noise regulations. The fact that these are cleaner, safer, and cheaper to operate is just icing on that cake.
