Visitors to the Finnish pavilion at Expo 2020 over the next five months will be able to enjoy fully sustainable brewed coffee, courtesy of Wärtsilä, and Paulig, a family-owned international food and beverage company known for its strong portfolio of coffee brands. We are collaborating with Paulig to show visitors how a cup of coffee can be brewed using innovative Power-to-X technology. The Power-to-X demonstration unit takes CO₂ from the indoor air and converts it in a biomethanation process into synthetic methane, which then powers the coffee machine. The demo unit is designed to showcase how future fuels can be part of a 100 percent renewable energy future.
