You may not think you'll see wind turbines around airports, but it's really not that unusual as more and more airports around the country and around the world are working on the green effort to conserve energy and be more eco-friendly.

From the air turbines to other alternative energy sources to energy efficient lighting and recycling, airports are taking on the challenge of being more energy and cost efficient, checking emissions output and doing more to help out the environment.

For instance, Boston Logan Airport has been awarded a LEED-certified terminal in the United States for its energy saving efforts.

According to,the U.S. Green Building Council awarded this certification for the Logan's green buildings, which were built from a high percentage of locally manufactured building materials.

Gates that are not currently occupied have lights that will automatically turn off and "large and airy glass walls" let natural light in reducing the use and cost of artificial light and heating.

Logan Airport is also incorporating wind turbines that can generate up to 3 percent of the energy needs of the airport.

Other airports using alternative energy are Denver International and Fresno Yosemite where they've both installed solar panels to help out with energy costs. Because of the high cost generated through airport energy use, any amount saved can be substantial.

Taking Off with Recycling

Recycling has also taken on a big role in airports, not only through the airport itself but also in the individual businesses and restaurants housed there. This is a pretty low cost effort that helps the environment in a big way.

Hartsfield-Jackson in Atlanta is making an effort to reduce water usage by redoing and installing low flush toilets in the bathrooms. With the amount that airport bathrooms are used, this is an efficient way to save water use in the airports.

San Francisco International Airport is offering "hydrating stations"where passengers can refill their water bottles to save on the use of plastic. Other efforts to save on waste include other recycling plans like composting Starbucks coffee grounds, reusing recycled organic cooking oil, and electronic trash monitoring devices in Seattle-Tacoma Airport.

There's so much airports are doing, including watching emissions and switching to greener fuel for the airport vehicles while using sustainable and renewable resources.

The Airports Going Green Conference will be held in November of 2013 in Chicago. Not only is this a chance to award achievements, but also to learn about the ecofriendly and sustainable practices that more and more airports are putting into use.

The aviation industry does not have to have a reputation of fuel and resource waste, it can lead the pack in the green movement.

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.
