Are Colleges Working to Save Energy?

You often hear about how businesses are making changes to save energy.

However, they are not the only organizations that see the cost savings potential in energy-saving programs and products. Colleges and universities are also trying to find new and unique ways to save money on campus.

Here is a look at some of the ways they are saving energy and the leaders at the forefront.

University of California

While most colleges and universities have to make changes to the way they do things, new campuses can take advantage of energy-saving methods from the beginning. An example of this is the Merced campus for the University of California.

When the campus was being built, it planned for many sustainable principles, such as water conservation and recycling. All of the buildings either met or exceeded the LEED Silver Standard. It also utilized multimodal travel as part of the transportation system.

University of British Columbia

The University of British Columbia is saving the school $7,000 each year with its program of sustainability.

It features coordinators to promote conservation with the residence buildings. A Universal Transportation Pass provides unlimited access to various public transportation options. This results in less congestion and emissions around campus.

Oregon Institute of Technology

Geothermal energy is the focus for the Oregon Institute of Technology.

It uses a direct-use system with three geothermal wells to provide the heating for the campus.

The cost of the system is $35,000 each year, which is considerably less than a natural gas boiler system that costs at least $250,000 per year to operate. The system has been in place since 1964, proving its long-term use and benefits.

University of Iowa

This is another school focused on saving energy on heating.

It has moved from coal to biomass with a new facility to provide all of the heat for the campus and approximately 30 percent of the electricity. It has saved the school more than $500,000 in the cost of fuel. It also reduces the amount of volatile compounds in the air.

Many other colleges utilize methods of saving energy by using occupancy sensors to shut off lights when the room is not in use.

The lights are also upgraded to be more efficient. Computers and appliances are two other areas where campuses can conserve energy and save money.

Even those colleges that cannot afford to upgrade major heating and cooling systems can benefit from small changes in their campuses.

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.
