It is expected that sic2022 will usher in a growth inflection point, and the global market space is about 700-1 billion US dollars. In order to accelerate the growth period from 2024 to 2026, the market space is about US $1.5 billion. In order to accelerate the growth period from 2024 to 2026, the market space is about US $2.1 billion
5) Energy calculation - Q: how much energy savings can silicon carbide bring at the vehicle end in the era of carbon neutralization?
A: the energy saving of SiC per vehicle compared with that of Si material for one year: 1) it is equivalent to saving 5.5 barrels of oil per car per year; 2) the owner saves more than $146.15 in power cost per year; 3) it reduces 690kg of CO2 greenhouse gas emissions per year
