In Part 2 of this series we dig deeper into the specifics of laterites, one of the two main nickel ore types and look at smelting, the most common processing technique.
Let's dive into this new series of articles on sustainability, treatment processes and innovations in nickel production, starting with nickel ores.
Nickel can be found in many forms from nanowires to stainless steel alloys. But what are the properties of nickel that make it an essential element in batteries?
The new EU Battery regulation has implications for nickel producers both inside and outside Europe. If they are supplying material to the EU battery chain destined for the European market all producers need to comply with the new rules.
Because the first step in reducing emissions is to measure them, the Nickel Institute has produced guidance to help nickel metal producers calculate their GHG emissions.
The European Commission published its proposed EU battery regulation in December 2020. After almost two years of discussion, the EU institutions are now in the final stages of negotiating the details. It could be adopted in December 2022, with entry into force to follow in 2023.
Batteries, notably those used in electric vehicles, play an essential role in the plans of the European Commission to deliver the EU Green Deal. They are considered as a critical and strategic technology to achieve Europe´s ambitious climate change mitigation targets and to move towards green and sustainable mobility.
The proposed Regulation will introduce a wide range of sustainability requirements and promote the recycling of key battery raw materials like nickel. EU legislative work is entering a crucial phase.
Nickel-based alloys and nickel-containing stainless are playing key roles in an emerging source of renewable energy known as thermal solar plants or concentrated solar power (CSP). Their use has enabled the industry to overcome challenges in heat transfer and thermal storage technology.
The short answer is: yes, nickel can be a sustainable material throughout the entire value chain, from mining, manufacturing, to use and end of life – if all actors throughout the value chain step up and take their responsibility. Now let's look at the longer answer...
Ever-tightening sulphur oxide (SOx) emission regulations are increasing the use of marine scrubbers globally. Scrubbers operate in a highly corrosive environment and require the resilience of nickel-containing alloys to prevent failure.
European nickel producers need a consistent regulatory framework. There must be coherence between different EU policy objectives with rules based on principles of sound science, risk-based approaches, full life-cycle thinking and impact assessments.
Most nickel production is destined for stainless steel. But a significant 8% is used in the production of alloy steels which are needed to deliver specific characteristics for specialised and often critical applications.
