In October final yr, Volvo Group unveiled the world’s first automobile made utilizing “inexperienced” metal. The autonomous electrical truck weighed eight tonnes and was designed to be used in quarries and mines.
It was the results of an industrial partnership between Swedish steelmaker SSAB, the state-owned electrical energy generator Vattenfall, and iron-ore miner LKAB. Their intention was to make the primary metal freed from fossil gas by changing the coking coal historically utilized in its manufacture with inexperienced hydrogen.
The partnership, dubbed “Hybrit”, is on the cutting-edge of European trade efforts to develop extra energy-efficient, low-carbon manufacturing methods.
Many initiatives have been already beneath means earlier than the coronavirus hit, however the pandemic has centered industrial leaders’ minds on the significance of reshaping and strengthening provide chains, and dealing with longer-term challenges — specifically, local weather change.
“It’s not concerning the lowest price producer, it’s about resilience in your provide chain,” says Stephen Phipson, chief govt of British commerce physique, Make UK.
Manufacturing executives within the UK, he factors out, are re-evaluating ‘just-in-time’ manufacturing processes and the way a lot stock to carry in future to make sure better resilience. The significance of abilities has additionally moved up the agenda, particularly as corporations battle to draw and preserve staff after the pandemic, which has left many in need of workers.
However enterprise leaders warning that wholesale transformation won’t occur in a single day.
A survey by McKinsey final November underlined the challenges. In a earlier survey, in Could 2020, most corporations acknowledged that they deliberate to pursue a number of paths to enhance supply-chain resilience, together with diversifying provide bases. However, in apply, by the tip of 2021, most had primarily elevated their inventories.
The more moderen survey discovered that 61 per cent of corporations had elevated stock of important merchandise and 55 per cent had taken motion to make sure they’d no less than two sources of uncooked supplies. Solely 11 per cent had “nearshored” manufacturing, to keep away from the dangers of disruption from geographically distant suppliers.
Duncan Johnston, UK manufacturing chief at Deloitte, says: “Altering issues in manufacturing takes time. You may’t change what was a world provide chain into one thing that’s extra near-shored or UK-centric in a short time”.
Local weather Capital

The identical, he says, is true of sustainability ambitions. Whereas corporations have finished some eager about it, they haven’t but “actually launched into the substantial journey that’s wanted to scale back carbon emissions within the UK financial system”.
Producers face a number of challenges alongside the way in which. Aside from decreasing the emissions in their very own processes, they should contemplate these of their provide chain. They should discover new methods to energy their actions and, in some instances, such because the automotive sector, utterly re-engineer their merchandise.
Heavy manufacturing industries, equivalent to metal and cement, are amongst these on the forefront of efforts to decarbonise nations’ economies. Outdoors of energy technology, the iron and metal sector is the biggest industrial producer of carbon dioxide. It accounts for 7 per cent-9 per cent of all direct fossil gas emissions, in keeping with the World Metal Affiliation.
To satisfy international local weather and vitality targets, the metal trade’s emissions should fall by no less than half by the center of the century, in keeping with the Worldwide Vitality Company. Reaching such a discount would require greater than incremental enhancements within the effectivity of conventional blast furnaces.
“We’ve come to a degree the place, by way of effectivity enchancment efforts, there’s not rather more room left,” says Martin Pei, chief technical officer at SSAB. “It’s actually breakthrough know-how that we’re taking a look at now.”
Within the blast furnace course of, corporations use carbon to take oxygen from iron ore to get iron. SSAB will as a substitute use clear hydrogen fuel, produced in a facility referred to as an electrolyser powered by Sweden’s considerable renewable electrical energy. The output can be a strong intermediate, referred to as sponge iron, which matches into an electrical arc furnace, the place it’s combined with scrap and refined into metal.
The profitable manufacturing of Volvo’s first heavy-duty truck reveals that the “entire worth chain works,” says Pei.
SSAB has estimated that metallic from its hydrogen-based course of will, no less than initially, be 20-30 per cent dearer than standard manufacturing. Pei, nevertheless, says that clients are eager and that demand for greener metal is rising as an increasing number of corporations decide to decarbonising their provide chains.
Policymakers might want to play their half, too, in serving to producers transition to a low-carbon financial system. For Europe’s metal trade to change en masse to hydrogen, for instance, would require a large growth of renewable energy. State assist can be wanted to fund the mandatory funding in increasing energy grids and different infrastructure to accommodate the transformation to low-carbon economies.
Hydrogen is a primary instance. The EU and the UK have each revealed formidable plans to develop a hydrogen financial system however obstacles stay to creating this a business actuality.
For instance, says Phipson, the UK has a “very small revolutionary sector on hydrogen . . . the problem is to scale that up”. Britain, he provides, is excellent on innovation and analysis funding however what is required is “scale-up capital”.
As for funding sources, he says: “There’s a large dedication from corporations to make use of non-public capital however the authorities additionally must play its half.”

Remodeling the workforce to cope with this transition is one other concern. Even earlier than the pandemic, producers have been frightened concerning the results of an ageing workforce and entice youthful expertise with extra digital abilities.
“We don’t know any manufacturing enterprise that has as a lot in the way in which of digital abilities as they want,” says Johnston.
These worries have grown, with many employers rising from the pandemic with much more unfilled jobs. Phipson desires to see extra motion from the federal government on this entrance, as nicely.
“[It] must get extra formidable about its abilities,” he believes. For the time being, the talents scarcity is a “drag on development”.
