Novel Direct Coal Power Technology Eliminates Combustion, Captures CO2
Electrochemical oxidation system converts coal to electricity without steam cycle or turbines, capturing high-purity CO2 for chemical feedstock conversion
Quick Look
- A novel direct coal power technology uses electrochemical oxidation to convert pulverised coal into electricity without combustion, eliminating CO2 emissions.
- The process feeds purified coal powder into an anode chamber while supplying oxygen to the cathode, generating electricity directly across an oxide membrane.
- High-purity CO2 captured at the anode outlet can be catalytically converted into synthesis gas or mineralised into compounds like sodium bicarbonate.

Why It Matters
This article describes a technological innovation in coal power generation that addresses the environmental concerns associated with traditional coal-fired power plants. The technology represents a potential bridge between existing coal infrastructure and cleaner energy solutions.
"Coal-fired power" conjures images of heavy pollution, steep carbon footprints and modest efficiency. But a novel, direct coal power technology challenges that stereotype by eliminating combustion entirely and sidestepping the CO₂ emissions that have long defined coal use. In this system, coal is pulverised, dried, purified and subjected to surface pre-treatment before being fed into the anode chamber of the cell. Oxygen is supplied to the cathode, and within the cell, the fine coal powder undergoes electrochemical oxidation across an oxide membrane, yielding electricity directly – without any intermediate steam cycle or mechanical turbine. At the anode outlet, the high-purity carbon dioxide generated by the reaction is captured in situ and catalytically converted into valuable chemical feedstocks such as synthesis gas or mineralised into compounds like sodium bicarbonate.
