Siemens Gamesa Renewable Energy (SGRE), the world’s leader in the offshore industry, today launched the SG 10.0-193 DD, the company’s first 10+ MW offshore wind turbine.

According to the company, the newest wind turbine in the SGRE offshore product portfolio “builds on proven technology for maximum energy yield at all wind speeds. It offers the same reliability while improving profitability and reducing risk for customers”.

The 10 MW rating is made possible through a larger generator diameter, building on the proven SGRE Direct Drive generator technology.

“The new SG 10.0-193 DD combines experiences and knowledge from five generations of proven direct drive technology in one 10 MW turbine. A showcase of strong performance, swift time-to-market, and low risk in the offshore wind energy market,” says Markus Tacke, CEO of SGRE.

By increasing the rotor diameter to 193 meters, this new wind turbine offers up to 30% more AEP than its predecessor, the SG 8.0-167 DD. Its 94-meter-long-blades provide a swept area of 29,300 m². Each blade is almost the same length as one soccer field.

The technology on the offshore direct drive platform allows for the re-use of most components from previous generations, providing a short time to market. The prototype is expected to be installed in 2019 with commercial market deployment expected in 2022.

Andreas Nauen, CEO of the SGRE Offshore Business Unit said: “Siemens Gamesa has been applying its knowledge and experience directly into offshore wind turbines for decades. Utilizing proven components and concepts provides us with a strong, established value chain, with clear processes and skilled employees ready to go, leveraging on a fully-developed and industrialised supply chain.”

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
