Magnium is on a mission to reduce global carbon dioxide (CO2) emissions by 1% by 2040, through deployment of net zero magnesium.
Magnium will achieve its target for net zero production by 2030.
Our green magnesium metal is inclusive of carbon avoidance and carbon removal credits associated with production, with globally significant opportunities for carbon avoidance credits in downstream transport applications.
The burning issue
CO2 emissions are the primary driver of global climate change. It’s widely recognised that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But how this responsibility is shared between countries, governments, businesses, and individuals has been an endless point of contention in international discussions.
It is time for responsible individuals and businesses to step up.
To succeed a considered and practical approach is required from metal manufacturers. Production of iron, steel, magnesium, aluminium and more contribute over 23% to the annual carbon emmissons.
Global CO2 emissions for 2020 were 34.8 Gigatonnes, with magnesium metal production contributing 35.6 Megatonnes, or just over 0.1%.
The transport sector alone emits another 23% of global emissions. Between the two industries, we are responsible for 46% of global emissions. We use "we" here as we acknowledge that we are the problem unless we deliver the solution.
Carbothermic magnesium production has two integral roles in our 1% global emissions reduction target. One we control - the production of magnesium metal and one we do not, the downstream use of green magnesium metal. The usage of net-zero or green magnesium reduces global emissions by 35.6 Mega tonnes. Additionally, and critically, magnesium is the lightest of the structural metals. When magnesium replaces aluminium in vehicles it saves 29 tonnes of CO2 emissions over the vehicle's lifetime for each tonne deployed. Carbothermic processing reduces significant carbon emissions however it is the downstream impact on carbon emissions in the automotive industry that is the real win. The downstream carbon avoidance credits in the transport sector are oversized compared to CO2 emissions savings in magnesium green metal production. The substitution for example of magnesium for aluminium and steel into electric vehicles causes light weighting and provides an extended range of over 10%+ to vehicles.
The move into electric vehicles is real and happening overseas at an incredible pace, accelerated further by COP 26. For automotive and other OEMs to achieve their sustainability declarations they have to consider the sustainable sourcing of materials and components along the complete supply chain. Responsibly sourced net-zero magnesium metal will be fed into the supply chain. Every kilogram of net-zero magnesium replacing aluminium or heavier metals in the transport sector reduces CO2 equivalent emissions by at least 29kgs over its life.
Today, however, the predominant process for magnesium metal production is the WWII-era Pidgeon process which is emissions-intensive at a range of 27 - 35 tonnes of CO2 produced per one tonne of magnesium metal produced. The Pidgeon process is an inherently inefficient chemical path and difficult to abate due to the inefficacious use of dolomite and ferrosilicon (FeSi) and incompetent use of labour and energy. It is also emissions-intensive, landfill intensive, and very unhealthy and toxic to the communities that host Pidgeon process factories. It will need to be retired for countries to meet their net-zero commitments. Production is also concentrated in one country and supply is capricious and opaque. In the lead-up to the 2008 Olympics, without notice all magnesium metal factories in China were closed to allow the unhealthy emissions to disperse. Recently in mid-2021 China again closed many magnesium plants to meet emissions targets. World supply chains require a reliable sustainable out-put of magnesium metal to deploy into their supply chains. This was highlighted recently in discussions with one of the world's largest car manufacturers "we want to deploy magnesium metal into our supply chain as it extends range and safety of our vehicles. However, today, with an opaque, toxic, and unreliable supply chain that is not possible".
Global Production of magnesium will increase several fold to 8 million tonnes per annum by 2035 due to magnesium’s light weighting capacity in electric vehicles and the ability to extend a vehicles range.
The pidgeon process dominated by China produces 90% of the world’s export magnesium metal @ 27 tonnes CO2e/tonne Mg. The electrolytic process (USA/Israel/Brazil etc.) produces the balance of 10% of the world’s magnesium metal @ 18 tonnes CO2e/tonne Mg.
Magnium deploys the carbo-thermic process and will produce net zero Magnesium metal by 2030.
|Pidgeon||27 tonnes CO2e/tonne Mg|
|Electrolytic||18 tonnes CO2e/tonne Mg|
|Carbothermic (Magnium)||0 tonnes CO2e/tonne Mg|
Magnesium is a lightweight champion among structural metals. We need to make it efficiently, cleanly, and reliably and now have the technology to do so. Through greater deployment of net zero magnesium we can reduce global emissions by 1%+.
Also, for every tonne of magnesium metal used in across electric vehicles this further reduce global CO2 emissions for each vehicle by 29 tonnes.
Magnium is taking responsibility for its entire carbon footprint and cleanly producing and supplying the lightweight metals needed for a decarbonised world.
