  • We found that the EV powertrain is $4.6k cheaper to produce than we thought and there is more cost reduction potential left. Consumer cost of ownership (TCO) parity vis-à-vis combustion engine (ICE) cars can be reached from 2018 (first in EU), creating an inflection point for demand.
  • Our detailed analysis of moving and wearing parts has shown that the highly lucrative spare parts business should shrink by ~60% in the end-game of a 100%-EV world, which is decades away.
  • EVs are an opportunity for tech companies because the electronics content in the Bolt is $4k higher than in an ICE car, excluding the battery.
  • ...3 more annotations...
  • Commodities-wise, we detected the highest deviation in weight shares between the Bolt and ICE car in copper, aluminium, battery active materials and rare earths.
  • Highest impact on markets for aluminium, copper, battery active materials, rare earths (all positive) and platinum group metals (negative).
  • Therefore, the cost difference (not the retail price difference) between the Bolt and the VW Golf, which we consider an equivalent ICE car, appears set to shrink to $2.3k.

climate europe planning

  • Industry groups, such as the European Round Table of Industrialists (ERT) and BusinessEurope, are pushing for the continued allocation of a set amount of free permits, arguing that full auctioning of permits would be too costly and would drive factories and jobs out of the EU
  • Over the weekend (20 January), one Commission official confirmed the plans, saying that the EU's aluminium, steel and cement industries would only be subjected to full permit auctioning gradually over a period of several years, reported Reuters.
  • But the EU executive may scrap certain elements of its original plans, including the idea to force member states that fail to reach interim targets to grant third country companies access to domestic renewables support schemes, according to ENDS Europe.

    "Icelandic singer Bjork, known for her political activism, urged parliament on Monday to review the planned sale of a local geothermal energy company, saying the deal could harm Iceland's interests. Environmental issues have caused friction in Iceland before, with construction of a power plant for an aluminium smelter triggering street protests in 2005. Bjork said she was unhappy with the sale of Icelandic power company HS Orka to Canada's Magma Energy (MXY.TO: Quote) and asked members of parliament to review it."

    In electrical applications, aluminum can do everything that copper can, but more efficiently and economically. Aluminum provides up to twice the conductivity per pound of copper (dependent on the specific alloy and application) at less than half the cost per pound (based upon current prices) for a 400% economic-efficiency advantage over copper.
