While all this sounds promising for the environment, EVs don’t automatically translate into lower GHG emissions. According to World Auto Steel (WAS), the emissions from vehicle production will be greater than the amount of emissions from driving. As such, it is becoming increasingly important for manufacturers, policymakers and consumers alike to view material options by considering its life cycle assessment (LCA).

World Auto Steel Case Study

WAS conducted a case study in which they compared two popular lightweight materials for EVS; aluminum and Advanced High-Strength Steel (AHSS). The study followed the University of California Santa Barbara Automotive Energy & GHG Model (UCSB Model) for a comprehensive analysis of each material’s total energy use throughout its entire life cycle, from production to end of life recycling. For the study, WAS examined 1,000,000 BEVs of equal range that were made up of either entirely aluminum or AHSS.

The study found that automakers can make over 17 percent more BEVs made of AHSS than aluminum BEVs with the same amount of energy. In other words, with the energy it takes to make 1 million aluminum BEVs, automakers can make 1.17 million AHSS BEVs.

Why is AHSS More Energy Efficient?

Aluminum production requires 8 times more energy per kilogram than steel production because the production process of aluminum is much more complicated and involves more steps than steel production. The aluminum BEVs in the study used up 30 percent more energy than those made from AHSS throughout its entire life cycle. Plus steel is 100 percent recyclable and can be reused almost indefinitely.

This poses a serious need to reexamine existing policies and regulations that only seek to reduce tailpipe emissions. By also taking into account emissions from the production of materials all the way to how a car is disposed at the end of its life cycle, automakers can grasp a better picture of the real impact of their choices on the environment.

A Sustainable Choice

As a solution-providing partner for automakers, steelmaker POSCO designed the perfect AHSS for cars that is lightweight, extremely strong, highly formable and environmentally friendly. POSCO GIGA STEEL belongs to the highest category for tensile strength of greater than 1GPa (Gigapascal). It can withstand more than 100 kg of force per square millimeter, making it 3 times stronger than aluminum. It is also 3.5 times cheaper than aluminum and 2.1 times cheaper to manufacture.

POSCO GIGA STEEL is three times stronger than aluminum.

In 2016, POSCO sold 9 million tons of steel sheets for cars, making up 10 percent of the entire global automotive market for steel sheets. POSCO GIGA STEEL was designed to further improve the performance and efficiency of POSCO’s auto partners around the world. As the auto industry heads towards a future where environmentally-friendly EVs become the norm, POSCO will strive to equip its auto partners with the materials and tools necessary to stay ahead and competitive.

At the Forefront of Korea’s Marine Ecology Conservation: POSCO Volunteers for Clean Ocean 

POSCO Volunteers for Clean Ocean, established on November 25, 2009, is an organization committed to saving Korea’s waters. Its activities, carried out by members with professional experience in scuba diving, are varied: cleaning waters and beaches near company processing plants in Pohang and Gwangyang, aiding regional fisheries, lifesaving and salvaging sunken ships are all part of POSCO Volunteers for Clean Ocean’s efforts to protect and preserve Korea’s waters. In addition, the volunteer organization symbolizes the POSCO Green Environment Spirit by actively participating in marine conservation initiatives alongside various organizations in collaborative events such as Water Day and Oceans Day.

Passion? Check. Professionalism? Check.  

POSCO Volunteers for Clean Ocean has 780 passionate members, 270 of whom hold certified licenses for skin and scuba diving. The high level of professionalism makes it possible for the volunteers to engage in collaborative lifesaving efforts with other organizations such as the Coast Guard.

In August last year, POSCO Volunteers for Clean Ocean was shown on the popular KBS environmental documentary <Environment Special> displaying the Korean flag at Dokdo after removing the starfish that were damaging the ecosystem. Dokdo, a small island located in the East Sea, bears great significance to Korea as the nation has been in continuous debate with Japan over which country is the rightful owner. Such passionate activities were made possible by regular meetings and training: the organization meets every Saturday to preserve Korea’s oceans such as collaborating with regional schools and local residents to improve the coastal environment and ecology.

Interview: POSCO Volunteers for Clean Ocean President Jong-bin Park on the Organization and its Future

“We will focus on recovering the marine ecosystem and make a tangible contribution to the fishing economy.”

I remember the early days of the POSCO Volunteers for Clean Ocean when some fishers were concerned about the impact our activities might have on their farms. Recently, however, local communities are competing to invite us as we have demonstrated over time our contribution in recovering the marine ecosystem. Local governments are inviting us to various environmentalist events, which helps us establish our corporate image as a core volunteer group as well as leading to more opportunities to participate in joint efforts to improve regional communities.

Our next plan is to raise awareness of eco-friendly steel material by integrating them into our volunteer activities. Recently, our members installed the artificial steel reef “Triton” in the waters of Guman-yi ri Dae-bo myun. We were surprised to see the marine ecosystem recovering rapidly due to the swift growth of marine algae following the installment of Triton. We also plan to make efforts to improve the fishing economy.

What is Triton?

‘Triton’ was named after a sea-god from ancient Greek mythology, who controlled all ocean. The key to Triton was something called a Steel Slag. It is a by-product of molten metal from melting iron ore, soft coal, limestone—the three ingredients for producing steel—in extremely high temperature. Steel Slag is an eco-friendly resource that can be widely used for many purposes such as cement, manures, and aggregates. POSCO’s ‘Triton’ is a low-carbon fish reef using such Steel Slag. It creates a healthy environment for marine life to flourish, by attracting the accession of marine plants in the area. [/box]

We hope that our readers were able to feel POSCO Volunteers for Clean Ocean’s passion for marine ecology preservation through this post. POSCO Volunteers for Clean Ocean will continue in its endeavors to save the waters of Korea.
