Zero Carbon Emission Based on Carbon-free World Power Grid

[摘要] This paper designs a globally smart energy frame for zero carbon emission covering electricity, transport, industry, etc. all sectors. Primarily, Carbon-free World Power Grid (CFWPG) is proposed here; converter-train as the pivotal technology is proffered, to construct Inertia-endowed Convert-station and DC Transformer for integrating remote generation, DC transmission, AC local grid and DC sub-grid into CFWPG configuration; supportive technologies including Multi-function Energy Storage are listed; the decisive factors of low-priced electricity are given. In order to prove zero carbon emission fully viable, non-carbon transport methods and carbon-free metal productions are particularly discussed as innovative improvement examples of other sectors. In the future, it is expected that more than 95% energy will be gained through CFWPG; production and energy consumption modes will be upgraded; and low-priced electricity will make carbon consumption become a luxury.
