Sweden’s SSAB says it has “produced the world’s first fossil-free metal” and has began delivering it to the Volvo Group, its first buyer.
The information represents the newest improvement for the Hybrit challenge, which was arrange in 2016 and is owned by SSAB, vitality agency Vattenfall and LKAB, a mining and minerals group. Each Vattenfall and LKAB are owned by the Swedish state. The concept underpinning Hybrit is to make use of “100% fossil-free hydrogen” somewhat than coal and coke in metal manufacturing.
In an announcement on Wednesday, SSAB known as the trial supply “an necessary step on the best way to a totally fossil-free worth chain for iron- and steelmaking.”
Trying forward, the aim is to develop the know-how so it may be demonstrated at an industrial scale. It is hoped this might occur as early as 2026.
“The primary fossil-free metal on the planet just isn’t solely a breakthrough for SSAB, it represents proof that it is doable to make the transition and considerably cut back the worldwide carbon footprint of the metal business,” Martin Lindqvist, SSAB’s president and CEO, stated.
Metal manufacturing is considered one of many industrial processes ripe for enchancment in relation to emissions and different metrics associated to sustainability. The problem is a giant one, nonetheless.
In line with the Worldwide Power Company, the iron and metal sector is liable for 2.6 gigatonnes of direct carbon dioxide emissions annually. In 2019, this determine was larger than the direct emissions from sectors similar to cement and chemical compounds.
The IEA provides that the metal sector is “the biggest industrial shopper of coal, which gives round 75% of its vitality demand.”
Hybrit just isn’t the one challenge trying to mitigate the consequences of metal manufacturing. One other, H2 Inexperienced Metal, plans to construct a metal manufacturing facility within the north of Sweden that might be powered by a “inexperienced” hydrogen plant.
Again in February the Swedish agency, which is backed by buyers together with Spotify founder Daniel Ek, stated manufacturing would begin in 2024 and be primarily based within the nation’s Norrbotten area. By 2030, the intention is for the enterprise to have the capability to provide 5 million tons of metal per 12 months.
Hydrogen may be produced in various methods. One methodology consists of utilizing electrolysis, with an electrical present splitting water into oxygen and hydrogen.
If the electrical energy used within the course of comes from a renewable supply similar to wind or photo voltaic then it is termed “inexperienced” or “renewable” hydrogen.
In addition to metal manufacturing, aluminum manufacturing is one other sector the place renewables might have a task to play.
Earlier this 12 months German automaker BMW stated it had began to supply and use aluminum produced utilizing photo voltaic vitality.
