This production method yields highly competitive “green” (or “renewable”) hydrogen. By integrating gasification, Sorption-Enhanced Water Gas Shift (SEWGS), and Pressure Swing Adsorption (PSA), we can achieve high purity at the site. Producing and using it locally lowers costs by removing the need for expensive cooling, compression, and trucking.
The Technology Breakdown
Char Gasification: Heats solid carbon (char) with steam to create a mix of hydrogen and carbon monoxide (syngas).
SEWGS: A clever one-step process. It uses solid materials to trap carbon dioxide inside the reactor as it forms. By removing carbon dioxide, the reactor naturally forces the creation of more hydrogen.
PSA: Acts like a molecular net. It catches impurities like remaining carbon monoxide and water. The result is ultra-pure (99.999%) hydrogen ready for fuel cells.
Maturity (TRL): PSA technology is highly mature (TRL 9) and used worldwide. SEWGS is currently at a moderate maturity level, progressing from pilot demonstrations (TRL 5-6) to full-scale commercial deployment.
Selling Price of Hydrogen
Global Standard: Traditional, fossil-based hydrogen market price roughly $5.50 to $7.50 per kilogram. Standard “green” hydrogen via water electrolysis typically sells for $5.00 to $6.00 per kilogram.
Local Char-Based Hydrogen: By utilizing biomass or waste-derived char and bypassing distribution and long-haul transport costs, the production cost can drop to roughly $2.00 to $3.00 per kilogram.
In-Situ Savings: Avoiding transport and storage means you save an estimated $1.00 to $2.00 per kilogram on logistical costs.
