Green Steel: Decarbonising with Hydrogen-Fueled Production

As the fight against climate change ramps up worldwide, the need for industries and economies to respond is immediate.

Of course, different sectors contribute different amounts of greenhouse gas (GHG) emissions, and face different paths to decarbonisation as a result. One massive player? Steel and iron manufacturing, where energy-related emissions account for roughly 6.1% of global emissions.

The following infographic by AFRY highlights the need for steel manufacturing to evolve and decarbonise, and how hydrogen can play a vital role in the “green” steel revolution.

The Modern Steel Production Landscape

Globally, crude steel production totalled 1,951 million tonnes (Mt) in 2021.

This production is spread all over the world, including India, Japan, and the U.S., with the vast majority (1,033 million tonnes) concentrated in China.

But despite being produced in many different places globally, only two main methods of steel production have been honed and utilised over time—electric arc furnace (EAF) and blast furnace basic oxygen furnace (BF-BOF) production.

Both methods traditionally use fossil fuels, and in 2019 contributed 3.6 Gt of carbon dioxide (CO2) emissions:

The Elemental Composition of a Human Body

The human body is a miraculous, well-oiled, and exceptionally complex machine. It requires a multitude of functioning parts to come together for a person to live a healthy life—and every biological detail in our bodies, from the mundane to the most magical, is driven by just 21 chemical elements.

Of the 118 elements on Earth, just 21 of them are found in the human body. Together, they make up the medley of divergent molecules that combine to form our DNA, cells, tissues, and organs.

Based on data presented by the International Commission on Radiological Protection (ICRP), in the above infographic, we have broken down a human body to its elemental composition and the percentages in which they exist.

These 21 elements can be categorized into three major blocks depending on the amount found in a human body, the main building block (4 elements), essential minerals (8 elements), and trace elements (9 elements).

The Elemental Four: Ingredients for Life

Four elements, namely, oxygen, carbon, hydrogen, and nitrogen, are considered the most essential elements found in our body.

Oxygen is the most abundant element in the human body, accounting for approximately 61% of a person’s mass. Given that around 60-70% of the body is water, (Read more...)
