Abstract
Coal consumption leads to over 15 billion tons of global CO(2) emissions annually, which will continue at a considerable intensity in the foreseeable future. To remove the huge amount of CO(2), a practically feasible way of direct carbon mitigation, instead of capturing that from dilute tail gases, should be developed; as intended, we developed two innovative supporting technologies, of which the status, strengths, applications, and perspective are discussed in this paper. One is supercritical water gasification-based coal/biomass utilization technology, which orderly converts chemical energy of coal and low-grade heat into hydrogen energy, and can achieve poly-generation of steam, heat, hydrogen, power, pure CO(2), and minerals. The other one is the renewables-powered CO(2) reduction techniques, which uses CO(2) as the resource for carbon-based fuel production. When combining the above two technical loops, one can achieve a full resource utilization and zero CO(2) emission, making it a practically feasible way for China and global countries to achieve carbon neutrality while creating substantial domestic benefits of economic growth, competitiveness, well-beings, and new industries.
