H2 Green Steel is building a steel production plant (in Boden, northern Sweden) that reduces the iron ore into green iron using 100% green hydrogen with near-zero emission. The heart of the plant is giga-scale electrolyzer, powered by renewable electricity (instead of coal) that splits water into its constituent parts: hydrogen and oxygen. Then in the reduction reactor the hydrogen reacts with oxygen in the iron ore, transforming the iron ore into sponge iron and producing (environmentally friendly) water steam. In the melt shop the iron is charged into an electric arc furnace, where it is mixed with steel scrap. It is then melted with a powerful electrode and alloys are added in a ladle furnace. The molten steel is transformed into solid products.

Vendy is building a used phone collection network based on AI-based kiosks that function like vending machines. User brings their old phone, connect it to the kiosk's Wi-Fi and place it in the booth for evaluation. The machine analyzes the device in just five minutes and immediately provides a binding offer. Using computer vision, it accurately identifies any defects: from minor scratches and cracks on the screen and back glass to even small dents on the case. If the price offer is accepted, the machine instantly transfers payment via the Swish payment system. Collected phones are refurbished and sold on marketplaces or sold to manufacturers for the recovery of useful materials and parts.
