It is now widely accepted that it's imperative to transition away from traditional coal combustion. Which is the single largest source of global temperatures rising. This no longer a matter of debate but a necessity for climate stability. However, research increasingly suggests that "phasing out" coal does not have to mean abandoning the resource entirely. Instead, converting coal into sustainable fuel forms like hydrogen and synthetic natural gas (SNG) through gasification, coupled with Carbon Capture and Storage (CCS), offers a pragmatic pathway toward a decarbonized economy.
Technical Feasibility and Hydrogen Production.
The cornerstone of sustainable coal conversion is "gasification". Unlike traditional combustion, gasification breaks down coal into its chemical components—primarily hydrogen and carbon monoxide (syngas). According to the International Energy Agency (IEA, 2023), coal gasification with CCUS is currently one of the most cost-effective methods for producing "blue" or low-carbon hydrogen. While electrolytic hydrogen (green hydrogen) remains the ultimate goal, current costs range from $6.00 to $9.30/kg, whereas coal-based hydrogen with CCS can be produced for approximately $1.60/kg (IEAGHG, 2025).
Research from the Andlinger Center for Energy and the Environment highlights that modern gasifiers can convert over 99% of the carbon in coal into a concentrated stream of CO_2. This concentration is critical because it makes carbon capture significantly more efficient and less energy-intensive than capturing CO_2 from the diluted flue gases of standard power plants.
The Importance of the Transition and
the importance of this conversion lies in three key areas:
Energy Security: For coal-rich regions, converting coal into cleaner fuels ensures energy independence while meeting international climate commitments (APEC, 2025).
Infrastructure Repurposing:
Existing coal-fired infrastructure can be retrofitted with energy storage or biomass co-firing. A 2025 study on the Pego Power Plant in Portugal demonstrated that transitioning coal plants to biomass or synthetic fuel production maintains regional economic stability while slashing emissions.
A "Bridge" Strategy: The CSIRO and ICSC have noted that low-carbon hydrogen from coal can achieve life-cycle environmental impacts similar to renewable hydrogen when capture rates exceed 98% (IEAGHG, 2025). This allows coal to serve as a vital bridge, scaling the hydrogen economy until renewables can meet total global demand.
In conclusion,
converting coal into sustainable forms of energy is a viable strategy to mitigate the environmental "lock-in" of fossil fuel infrastructure. By shifting the focus from combustion to conversion, society can leverage existing resources to accelerate the path to net-zero.
