China Energy achieves world’s first ever co-firing of 50% hydrogen and 50% coal at pilot power plant Several Asian countries plan to co-fire ammonia and coal, with hydrogen previously deemed too unsuitable for existing coal-fired power plants Technicians operating the 40MW pilot power plant during co-firing of 50% hydrogen and 50% coal. The dot-matrix display reads: “The hydrogen-blended combustion ratio of Yantai Longyuan's 40MW coal-fired boiler has successfully reached 50%.” Photo: Longyuan

Underground CO₂ injection could boost geologic hydrogen production — but only in the right rocks and at the right temperatures: study The added CO₂, however, can also produce chemical reactions that will clog the rock’s pores faster than water alone, thus reducing the amount of time in which H₂ can be produced A diagram from the study highlighting the increase in geologic hydrogen production that can be derived from CO2 injection.
