The article highlights the ongoing surge in funding for startups focusing on hydrogen energy, with companies securing large rounds for various technologies related to hydrogen production and utilization. ZeroAvia, a California-based developer of hydrogen-powered airplane engines, recently completed a $150 million extension round. Globally, at least 23 hydrogen-focused startups have raised over $1.4 billion in equity funding this year, targeting areas like heavy-duty trucks and electrolyzer production. China stands out as a key player in hydrogen investment, leading in electrolyzer capacity and manufacturing. Other regions, such as Australia and the U.S., also witness substantial funding rounds for hydrogen startups. Notably, the U.S. allocated $750 million to support clean hydrogen projects. However, not all companies in the hydrogen space are thriving, as seen with Hyzon Motors facing financial challenges post-IPO. Despite hurdles, private investors continue to show strong interest in hydrogen-focused startups while the IPO market remains cautious.
