Osaka Gas invests in US-based ammonia start-up Osaka Gas, through its US subsidiary Osaka Gas USA, has invested in Starfire Energy, a Denver-based green ammonia start-up, it said on April 9. Startfire is developing systems to produce green ammonia from renewable energy, air and water, and systems to crack ammonia into hydrogen. This system will leverage ammonia’s use as a carrier for hydrogen, Osaka Gas said. Other investors include AP Ventures, Chevron, New Energy Technology, and Mitsubishi Heavy Industries. Starfire was founded in 2007 to develop renewable energy solutions, which later evolved into a focus on small-scale distributed ammonia production modules and technology for cracking ammonia into hydrogen to generate electricity.
