GE Renewable Energy and MHI Vestas Offshore Wind to use some of the world's largest testing rigs
Clemson University’s SCE&E Energy Innovation Centre is home to the US’ largest wind turbine testing rig.
The 15MW rig is 20ft wide and over three stories tall is one of the largest rigs in on the globe, located in South Carolina.
The university also owns a smaller, but still powerful, 7.5MW rig, which is used for mechanical and electrical testing.
In 2013, the university used US$100mn of funding, from federal, state, and private investors, to lower the time of bring offshore wind projects to the market.
MHI Vestas Offshore Wind, the subsidiary of Danish Vestas Wind Systems and Japanese Mitsubishi Heavy Industries, has signed a contract to use the 15MW rig for tests.
It will test its 9.5MW turbine over a period of five years, at the price of $23mn.
The Connecticut-based GE Renewable Energy has also signed a multi-year contract for the use of the 7.5MW rig.
“The Clemson testing facility represents a critical investment to ensure America leads in this fast-growing global industry — helping to make sure the best, most efficient wind energy technologies are developed and manufactured in the United States,” commented Daniel Poneman, former Deputy Secretary of Energy.
Trafigura and Yara International explore clean ammonia usage
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.
