SNBC under resource constraints: electrification, this sector at the heart of decarbonization which relies on the use of critical resources

TECH-NEWS

A outline of the resource-constrained SNBC study is offered for transfer on the Capgemini Invent website. the total version is available here . The challenges of this study also are mentioned in our interview with Emmanuelle Ledoux , Director General of INEC. Electrification is at the middle of low carbon ways an important energy carrier, electricity is AN integral a part of all public decarbonization situations . the rise in carbon-free electricity wants can therefore need the installation of recent production units (nuclear, solar, wind) additionally to hydropower and different types of thermal production supported biomass. relating to mobility, the huge electrification of road transport is currently announced. in step with the study, within the main scenarios, road electrification is therefore calculable between 91% and 99% for the fleet of sunshine vehicles and between 17% and 70% for the fleet of significant vehicles in 2050. Lithium, metal, platinoids and rare earths: essential and extremely strategic resources Lithium, cobalt and platinoids are fully essential resources for the transition to electrical mobility. Given the rise in demand, however, it’s estimated that the out there reserves are going to be exhausted inside fifty years. Moreover, 3 manufacturing countries, as well as China and Russia, share the bulk of the extraction and first process market, that poses obvious geopolitics problems, particularly within the current context. If rare earths aren’t essential from the purpose of read of earth science availability, it’s yet again a geostrategic issue, with China dominant over 80% of this world market.

Mixing the solutions: the best option?

This issue of criticality is a major problem in the medium term, as the European Parliament voted in favor of banning, from 2035, the sale of new gasoline or diesel engine vehicles!

Wouldn’t it be better to mix the solutions, rather than going 100% electric?

In any case, this is the opinion of Alain Chardon (Capgemini Invent), co-author of the study: “If we add up the resources used both for the construction of the vehicle and the fuel itself, we realizes that it is preferable to mix solutions, rather than going 100% electric. »

Moreover, concerning hydrogen mobility , the study makes an interesting observation. From the point of view of resources, the electric car is more critical than the hydrogen car [2]  ! Indeed, compared to electric vehicles, hydrogen vehicles have an advantage: “Their tank and their fuel cell allow them to have a much smaller battery. »

Then he adds: “Before, we had solutions, one fit for all (universal). Oil was used for everything. When we had a solution, we applied it everywhere, it was practical. When we take into account all the constraints (climate, criticality, biodiversity, cost, social impact, etc.), we understand that now no solution can solve all the problems.

While most large companies are in the process of switching to electric vehicle fleets, this study demonstrates that from the point of view of resources, this is not an ideal solution, with each vehicle carrying 300 to 400 kg of battery. On the other hand, for suburban journeys of a few kilometres, we show that the use of small electric vehicles (electrically assisted bicycles, electric scooters, Citroën AMI-type vehicles) is a good alternative.

In France, the term “sobriety” is frowned upon, because misunderstood. Let’s not forget that the translation of the word sobriety, in English, is sufficiency, which means “to use only what is sufficient for our needs or our objectives”. From the point of view of the decision-maker in business, as in individuals, asking the question of objectives and sobriety means doing strategy: what is vital, what is superfluous , or even counterproductive or harmful? »
