Digital Realty and Citi: clean energy data centres
Part of Digital Realty’s ongoing mission to use clean energy across its operations, the contract will represent 30% of the company’s total power requirements.
Citi will provide more than 260,000 MWh per annum - 55% of the output generated from the 162 MW Glasscock County wind farm project - which will power Digital Realty’s 13 data centres in Dallas, Texas.
Making digital greener
A. William Stein, CEO of Digital Realty, considers the deal emblematic of the direction that companies advancing the digital era must pursue.
"The data centre industry underpins the growth of the digital economy, and we believe it is critical for industry participants to recognize the importance of managing the environmental impact of their digital infrastructure.
"We're dedicated to supporting our customers with sustainable, highly resilient facilities that leverage renewable energy and other energy-efficient technologies.
“We're proud to be partnering with Citi, a proven leader in sustainable financing, to bring clean, renewable energy to our customers and we look forward to furthering our sustainability strategies with customers across the region and around the world,” he said.
Similarly, Roxana Popovici, MD at Citi, was buoyant that digital infrastructure is starting to transform with eco-consciousness in mind.
"As more companies like Digital Realty invest in renewable energy, we've committed to supporting them in their environmental endeavours as part of our efforts to accelerate the global transition to a low-carbon economy.
"This agreement represents an important step in powering Texas data centres with renewable energy and we're excited to be supporting the effort,” she added.
For Digital Realty, the deal represents the latest development in its long-term commitment to renewable energy. Similar past projects include a 50 MW of eco-friendly power for its Ashburn, Virginia data centres and 120,000 MWh green energy tariff with Portland General Electric for its Hillsboro, Oregon project.

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.
