Up Catalyst has closed a €2.36mn seed extension round to accelerate the development of an industrial pilot reactor that turns CO2 emissions into carbon materials. According to the Tallinn-based startup, the reactor will be able to produce 100 tonnes of CO2 per year. These can deliver 27 tonnes of advanced carbon materials, such as carbon nanotubes and graphite — a key component of EV batteries. The company’s technology isolates CO2 from flue gasses from heavy industry emitters. It then uses a process called molten salt electrolysis to turn it into green carbon. “We’re essentially electro-transforming carbon dioxide gasses into carbon…
