Clean energy technologies saw a record influx of investment last year: $1.7 trillion in total. But that still falls short of what’s needed to meet climate goals. With venture capital investment now falling, it’s increasingly difficult for startups to gain traction.  Claire Curry, global head of technology, industry & innovation at BloombergNEF, follows the journeys of many young companies in the clean-tech space. On this week’s Zero, Curry tells Akshat Rathi about the kinds of innovative pathways that have proven successful. LanzaTech, for example, a nine-year-old carbon recycling technology company, works with Chinese steel companies looking for low-emissions solutions. H2 Green Steel also scaled quickly, in part through agreements reached with Mercedes Benz, IKEA and other big brands looking to access low-carbon steel. Curry explains how these approaches could be replicated by other startups. Listen to Zero’s episode about green-iron startup Electra.
