Green hydrogen to be used for eco-friendly steel production in UAE

Growing awareness about climate change has pushed global economies to adopt renewable resources, leading to introduction of green energy in all walks of life. Following the shift towards solar and wind power to light up households and fuel electric vehicles, oil rich countries in the gulf are using their resources to create clean alternatives.

Electricity generated from the sun has also been used for industrial purposes, paving the way for the creation of eco-friendly aluminium in Dubai, which will now be used by carmaker BMW. Adopting a similar approach, the national energy firm in neighbouring Abu Dhabi has started producing steel, by using green hydrogen as a key component in the process.

Created through electrolysis that splits water molecules to capture hydrogen separately, the clean fuel will be used as a reducing agent by Emirates Steel at its facilities. The modification will significantly cut down emissions from the procedure, since hydrogen will replace coal, that is being phased out by various sectors globally.

Use of solar energy for electrolysis that leads to the extraction of green hydrogen from water, further ensures completely pollution free manufacturing.

But the Emirati firm Taqa isn’t stopping at hydrogen, and has gone a step ahead to produce green ammonia, which is 100% carbon free. As opposed to blue ammonia created from fossil fuels, the green version is the outcome of mixing hydrogen separated from water with nitrogen captured from air.

Easier to store and move around, green ammonia can be used as a fuel in power plants, and can also act as fertiliser to boost agriculture in the Emirati desert. Electricity for creating this clean alternative will come from photovoltaic cells, and Abu Dhabi also plans to export it across the globe.

Renewable resources are being explored for emission free industrial processes in different parts of the Middle East apart from UAE. For example neighbouring Saudi Arabia is using solar and wind energy to power up a desalination plant, that make sea water drinkable.
