The Siemens Energy and Dragados Offshore consortium snagged a nearly $7.7 billion contract for a trio of projects to transport 6 gigawatts (GW) of wind power in the German North Sea to shore.

The agreement with TenneT, a German-Dutch transmission system operator, was announced this week as the energy industry continues efforts to green up grids globally.

The projects involve supplying high-voltage, direct-current transmission technology for three grid connections—BalWin3, LanWin2 and LanWin4—to transport electricity from offshore wind farms to grid connection points north of Germany.

“In the global race against climate change, grid expansion must be able to keep pace with the accelerated expansion targets for renewable energies,” Tim Holt, member of Siemens’ executive board, said in a news release. “Shorter contracting processes, large-scale tenders and standardization of solutions show how grid operators and manufacturers are already pulling together to get green energy to consumers faster.”

Getting electricity from offshore wind turbines involves converting the energy from alternating current (AC) into direct current (DC) for transport to shore.

While Dragados will construct and install platforms needed for the projects, Siemens will manufacture the main electrical components, including switchgears, transformers and converter technologies.

TC Energy, Chemours Partner for Clean Hydrogen Facilities

Energy infrastructure provider TC Energy partnered with chemicals specialist The Chemours Co. to potentially develop hydrogen production facilities and associated infrastructure in West Virginia, the companies said April 19, having signed an agreement.

Located around Chemours’ Washington Works and Belle manufacturing sites, the proposed production facilities will be electrolysis-based and use the company’s Nafion ion exchange and proton-exchange membranes made in the U.S.

News of the agreement comes as companies and groups in West Virginia aim to establish the Appalachian Regional Clean Hydrogen Hub. Known as ARCH2, the hub—led by natural gas producer EQT Corp., science and tech not-for-profit Batelle, GTI Energy and energy tech firm Allegheny Science & Technology—is among the proposed hubs vying for some of the $7 billion in federal funding available to establish between six and 10 hubs across the U.S.

Both TC Energy and Chemours count among the companies participating in ARCH2.

As part of the agreement between TC Energy and Chemours, a non-binding offtake agreement for hydrogen produced by the project would be executed in support of Chemours’ facility demand, according to a news release. The excess hydrogen would be stored and made available to nearby merchant users.

The agreement covers the companies’ interest in developing, constructing and operating clean hydrogen production facilities and associated infrastructure.

Keppel, Exxon Mobil to Explore Low-carbon Ammonia Solutions for Singapore

(Reuters) Keppel Infrastructure and U.S. oil producer Exxon Mobil Corp. signed a memorandum of understanding (MOU) to develop low-carbon hydrogen and ammonia solutions for use in Singapore, the companies said in a joint statement on April 20.

The MOU comes as low-carbon energy demand surges in Singapore—and globally—and follows the city-state government’s hydrogen strategy launched in October last year.

Singapore’s National Hydrogen Strategy targets hydrogen to meet up to half of its power needs by 2050.

The deal announced April 20 has been signed through units of both the companies and aims to use low-carbon hydrogen for a 600-MW Keppel Sakra Cogen plant in Jurong Island.

Currently under construction, the plant is expected to operate with at least 30% hydrogen and would have the capability of shifting to run entirely on hydrogen.

The plant is expected to be completed in the first half of 2026.


Siemens, Lightsource BP Sign 1 GW Solar Inverter Deal

Lightsource BP has tapped Siemens to provide solar inverter stations for projects in the U.S. Midwest and Southeast as the Inflation Reduction Act spurs more solar sector growth.

As part of the volume frame agreement announced April 21, Siemens will supply more than 850 MW of inverters with an option to add 200 MW over the next two years, Siemens said in a news release.

Most of the projects will use 4.3 MW- to 4.7 MW-rated central inverter stations, which convert the DC electricity generated by solar panels into the AC electricity that powers electrical grids.

“The U.S. solar industry is poised for historical growth, with the Inflation Reduction Act offering tailwinds toward delivering 30% of our country’s electricity by 2030,” said Kevin Smith, CEO of the Americas for Lightsource BP. “Executing significant long-term procurement agreements with bankable, world-class suppliers like Siemens enables us to meet this urgent demand for sustainable, affordable energy and deliver on Lightsource BP’s industry-leading growth plans.”

Siemens Gamesa Unveils Sustainable Wind Turbine Tower

Siemens Gamesa said April 21 it launched a wind turbine tower, called GreenerTower, which is manufactured with sustainable steel that reduces carbon emissions by at least 63% compared to conventional steel.

“With more than 600 GW of new capacity to be installed worldwide in the next five years, it is important for the wind industry to reduce its carbon footprint,” Maximilian Schnippering, head of sustainability for Siemens Gamesa, said in a statement. “Our project to address emissions with greener steel is one such solution.”

The company is using a qualification process to verify that no more than 0.7 tons of CO2-equivalent emissions are permitted per ton of steel. The first qualifying supplier is German steel manufacturing company Salzgitter AG.

“The process to produce greener steel entails increased use of scrap steel, less energy-intensive steel manufacturing processes and an increased use of renewable energy sources,” Siemens Gamesa said in a news release. “As one of the measures to decarbonize steel production, for example, the electric arc furnace will be fed with green electricity from offshore wind projects.”

RWE and Siemens Gamesa plan to introduce 36 GreenerTowers at the Thor wind power project offshore Denmark, where 36 of the sustainable towers will be installed, Siemens Gamesa said.

Siemens Gamesa said the CO2-reduced tower will be available for onshore and offshore wind projects in 2024.
