Based on http://www.wolframalpha.com (checked March 29, 2019), hereby an extrapolation table demonstrating that the world is 5 to 15 times the EU. For markets that are based on demographics, a first approximation can be that the global long-term potential of a market is very roughly ’10 times EU’, or that EU represents 10% of the world market.
Today, the energy transition is well in progress in the EU. Tens of GW of wind and solar PV capacity are added every year. Transmission grids are being extended. We’re investing in energy efficiency. Buildings are getting smarter. The transport fleet is electrifying. We have 11 million heat pumps in Europe. As a result, we estimate that the energy transition has already added well almost 2 million tonnes of copper in use, and is adding about 300 kilotonnes per year: Continue reading The energy transition is in progress!
Through a rough back-of-the-envelope calculation we estimated to the total capital value of the EU electricity system, including generation, transmission & distribution and end-use. Continue reading Estimation of the EU electricity system capital value
The European annual motor market (all motor sizes) is 15 M units with an average copper content of 5.3 kg/unit. Annual copper use in this market is 79 ktonnes. This figure is expected to increase because of 2 drivers:
- Increased efficiency, which in general leads to higher copper use, leading to copper use of 6.5 kg/unit (~ 20% increase)
- Growth in the market to 20 million units per year, due to motorisation following electrification.
Hence copper use in the future EU motor market can be expected to be 130,000 tonnes per year, an increase of more than 50 ktonnes from today. Over the period 2018-2050, this leads to a an additional use of 1.5 M tonnes (50 k * 30 years). Considering that the average motor lifetime is around 15 years, and that copper in motors has an almost full collection and recycling rate, the demand for primary copper is half this amount, i.e. 750 ktonnes.
New motor technologies could reduce this amount by half. Therefore, in the alternative technology scenario, we reduce this figure to 500 ktonnes.
According to an ECI internal study, commissioned with Fraunhofer-i4e, the following demand for copper in truck due to electrification could be expected:
||Unit sales in 2025
Extrapollating these figures to a hypothetical full conversion to electromobility yields:
||Maximum copper needs
There are 13 million trucks on the EU’s roads (i.e. 5 times the annual market). The maximum copper needs to electrify 100% of the truck fleet is 350 * 5 = 1750 ktons.
In practice, alternatives to electrification of goods transport will also play their part. In addition, the sharing economy may lead to less consumption, more local consumption and hence less goods transport. A realistic scenario will reduce this figure at least by half, to 875 ktons.
At present, the EU industry uses 150 Mtoe/year of fossil heat through oil, coal, gas. This is equivalent to 1,800 TWh/year. If this industrial heat demand is converted to electroheating technologies, around 750,000 industrial furnaces will be needed. This leads to a new copper demand of 1.5 Mtons. This is based on the following assumptions:
- One furnace requires about 1.2 GWh of electricity (e.g. 400 kW for 3000 hours).
- Switching to electricity reduces final energy consumption by a factor 2.
- 2 tons of copper per furnace for the furnace, its power supply and cabling.
It is highly unlikely that industry will convert from largely combustion technology to electric furnaces, even in a strongly carbon-constrained world. Green combustion using bioenergy or hydrogen will also play an important role. For the moment, we assume that electricity, bioenergy and combustion will play equal roles, leading to 250,000 furnaces and a copper demand of 500,000 tonnes.
According to , there are 1.63 busses per 1000 citizens in the EU, leading to 828,000 busses for EU’s 508 million citizens. This estimate is not far from DecarbEurope’s number .
According to , copper use in electric busses is over 350 kg/unit. We assume that 2 thirds of the copper content is due to electrification, i.e. 230 kg.
Considering CAPEX parity for electric buses well before 2050 , we can expect the fleet to fully electrify, leading to a copper demand of 190,000 tonnes.
Bus charging stations need 224 – 369 kg per unit, leading to another demand of 185,000 – 305,000 tonnes (average 245,000 tonnes).
Hence, the total copper demand to electrify the bus fleet is 435,000 tonnes.
