‘We will make zero-CO2 hydrogen from natural gas so cheaply we could give it away for free’

US start-up H Quest says its emissions-free microwave plasma pyrolysis technology will turn methane into H2 and high-value solid carbon or petrochemicals — with these “co-products” alone making projects profitable, writes Leigh Collins

An H Quest engineer takes a spectral reading to measure the temperature of the reaction products. The glow is emitted by the white-hot carbon particles that were formed moments earlier within the high-speed flow of natural gas. Usually, this process is contained within steel tubes, but a clear tube was arranged for a photoshoot to make the process visible.
