Y Combinator-backed startup Rise Reforming is developing a modular, zero-capital technology to convert raw biogas into high-value green chemicals like methanol and dimethyl ether. The company automates the gas scrubbing and catalytic reforming processes to overcome traditional challenges like catalyst poisoning without relying on carbon credits for profitability. By deploying localized, fast-to-market units, Rise Reforming aims to undercut the transport and capital costs of large centralized chemical plants while providing a highly profitable alternative to renewable natural gas for smaller biogas producers.
