Microsoft has acquired Lumenisity® Limited, a start-up based in the U.K. that provides hollow-core fiber (HCF) with a proprietary design said to offer multiple advantages over traditional solid core fiber.

Per the company’s website, Lumenisity was formed in 2017 as a spinoff from the Optoelectronics Research Centre (ORC) at the University of Southampton to commercialize breakthroughs in the development of hollow-core optical fiber. In 2021 and 2022, it won the Best Fibre Component Product for its NANF® CoreSmart® HCF cable in the European Conference on Optical Communication (ECOC) Exhibition Industry Awards.

A press release said that Microsoft plans to use Lumenisity’s technology and experts to accelerate innovations in networking and infrastructure. It noted that light that propagates in an air core has significant advantages over traditional cable built with a solid core of glass, including increased overall speed and lower latency as light travels through HCF 47% faster than standard silica glass.

Hellenic Cables is one of 13 parties from eight countries that are part of a coalition working to further the design and deployment of a 6 MW floating wind prototype in the French Mediterranean.

A press release said that the pan-European project, launched in Paris, seeks to accelerate the roll out of the next generation of floating wind technology for a competitive, more scalable and industrial deployment. Other participants include: X1Wind, Naturgy, 2B Energy, Technical University of Denmark, Hydro, Ecole Centrale de Nantes, Schwartz Hautmont, Ocas, Tersan Shipyard, Ocean Ecostructures and Cybernetix.

Backed by the European Commission under the Horizon Europe program with public funding of €16 million, the project is anticipated to run until 2027. It will lead to the deployment of a 6 MW floating wind prototype to demonstrate at a relevant scale an innovative integrated downwind floating platform design, while advancing in parallel on the industrialization and scaling-up of the integrated solution up to 20MW+ scale, in preparation of commercial floating wind farms under development in Europe.

This project builds upon previous European Projects such as the PivotBuoy which recently led to the installation of a part-scale prototype in the Canary Islands to validate the technology. Design work for the initial 6MW system is currently underway and scheduled to be finalized in 2023. Construction is due in 2023 and 2024, ahead of installation in 2025.

Floating wind is considered one of the lowest carbon electricity generation systems to meet the energy demand in a sustainable way while inducing better competitiveness, less noise and visual pollution, and less interaction with the users of the maritime domain. The NextFloat Project represents a unique opportunity to test a novel and disruptive version of this technology at full scale, driving cost curve reductions in order to deliver industrial-scale projects at the earliest possible stage”.

“After the successful deployment and validation of our innovative low-cost solution in the Canary Islands (PivotBuoy project), the goal now is to scale-up and industrialize the technology in advance of large commercial floating wind projects which will come online at the end of the decade across European, Asian and U.S. waters,” said X1 Wind Founder and CEO Alex Raventos. “Wind will allow us time to drive substantial improvements in the competitiveness of floating wind as we prepare for long-term mass deployment.”

Germany’s Leoni AG reports that the May 21 announced sale of its Business Group Automotive Cable Solutions business to Thailand’s STARK Corporation Public Company Limited (STARK) has been upended.

A press release said that the buyer, STARK, “unexpectedly demanded very significant amendments to the purchase agreement.” It added, “Despite willingness to compromise on the side of Leoni, STARK refused to agree and will not perform the closing.”

Leoni said that it sees the actions as a breach of the contract, and will “take all measures to enforce its rights against STARK.” It noted that the sale was important as it is the basis for the financing of the Leoni Group until the end of 2025. Leoni has signed a comprehensive contractual documentation of the refinancing plan with its syndicate banks and borrower’s note holders on the basis of the agreement in principle reached in July 2022. An essential prerequisite for its implementation, however, is a partial repayment of financial liabilities with proceeds from the sale. As a result of the non-performance of the contract by STARK, the refinancing plan cannot be implemented for the time being.

The release did not state what changes STARK requested. STARK is a private organization which focuses on investment in manufacturing and services in the industrial sector. It has been registered as a public organization since 2019 and mainly runs the business of Phelps Dodge International (Thailand) Limited. In 2020, it partnered with Thai Cable International, a leading manufacturer and distributor of copper and aluminum conductors in Thailand, and Thinh Phat Electric Cable Joint Stock Company, a major wire and cable manufacturer from Vietnam.

STARK did not respond to a WJI request for comment.

NKT reports that the company is ready to design, produce and install a 1 kV cable using low-carbon aluminum and polyolefins in the Swedish power grid.

A press release said that the initiative will reduce the carbon footprint of the power cable significantly and is part of NKT’s ambition to become a net-zero emissions company. The cable has been developed in close cooperation with the Swedish power grid company Ellevio, which will also be the first customer to use it. Below, NKT spells out how the cable will achieve that goal.

The conductor is made from Hydro REDUXA low-carbon aluminum with 4.0 kg CO2e per kg of aluminum, less than a quarter of the global average. For insulation and jacketing, the company is using Bornewables™ material from Borealis that has -0.5 kg CO2 eq/kg. per kg of polyethylene (PE), which represents a reduction of at least 130% compared to conventional fossil-based polyethylene. Finally, the cable will be made with lean production processes that use 100% renewable electricity.

The cables will be manufactured with low-carbon aluminum and polyolefins at the NKT factory in Falun, Sweden, which is running on 100% renewable electricity. For NKT, the project is yet another important step in reducing the carbon footprint of its power cable solutions after also having announced the production of the world’s first HVDC power cable using low-carbon copper.

“This is a game changer in the development of an energy infrastructure built with innovative, low-carbon solutions,” said NKT Executive Vice President and Head of Applications Will Hendrikx. “We see a growing market demand for more environmentally friendly products and solutions and are proud to be among the first to deliver an innovative low voltage cable after a close collaboration with our customers and suppliers.”

Karolina Viksten, sustainability manager at Ellevio, said that cables and overhead lines account for some 60% of their emissions, and this new cable will be a big help.

Italian carrier Unidata has chosen Alcatel Submarine Networks (ASN) to supply a new subsea cable system, Unitirreno, that will connect Sicily with two cities on the Italian mainland, Rome and Genoa.

A press release said that the project will be the first 24-fiber pair open cable system in the Mediterranean region. There will also be a 16-fiber pair from a branch to Fiumicino near Rome, where Unidata is building a green data center hub. Cable performance will be capable of 20 Terabit/sec x fp -> 480 Terabit/sec. The layout represents the shortest, quickest path to Northern Europe from Sicily via Genoa/Milan: 9 msec. Latency will be half that or less than alternative domestic terrestrial backbone solutions.

Unitirreno will be 890 km long. It will connect Mazara del Vallo on the western tip of Sicily with Genoa on the mainland, and it will include a junction point near Rome. It will include stubbed branching units to allow future landings in Sardinia and/or Palermo.

“ASN will design, manufacture, and deliver the Unitirreno system with the state-of-the-art technology that has made ASN a leader in the telecommunications submarine industry,” said Paul Gabla, ASN’s chief sales and marketing officer.
