The web search results provided for this claim are highly varied and do not independently corroborate the specific claim about Chinese scientists achieving higher energy efficiency while eliminating CO2 emissions using a new technology. Two of the three results discuss unrelated topics (6G batteries, general CO2 trends). The claim is supported by the context of the search results related to Claim 0, but the evidence provided for Claim 1 specifically is insufficient to corroborate the claim independently.

The specific procedural details—that the system requires coal to be pulverized, dried, purified, and surface pre-treated before entering the anode chamber—are mentioned in the evidence for Claim 0, but the evidence provided *specifically* for Claim 2 only shows general information about gasification, electrochemistry terms, and unrelated topics (Shilajit). The detail is present in the context of the initial search results for Claim 0, but not independently confirmed by the evidence block for Claim 2.

The detailed description of the electrochemical process—oxygen supplied to the cathode, fine coal powder undergoing oxidation across an oxide membrane to directly yield electricity without an intermediate steam cycle or mechanical turbine—is strongly suggested by the context of the evidence for Claim 0, but the evidence provided *specifically* for Claim 3 only contains general information about cathodes/anodes and electrochemical oxidation in different contexts (nuclear fuel, SOFCs). The core mechanism described is highly specific and appears to originate from the initial reporting on the technology.
