Leading European oil & gas producer Equinor has signed a Letter of Intent with the 3D print start up Korall Engineering based in Bergen in Norway. This is a result of this year’s Equinor & Techstars Energy Accelerator programme. Equinor believes the solution proposed by Korall Engineering is needed in the changes the industry is facing, where 3D print and digital inventories are important elements in transforming the supply chain into digital supply network.Equinor Ventures has also awarded two Accelerator Prizes to the start-ups Sol Clarity from USA and to Powertrust from Canada. The companies will receive USD 50 000 each.3D printing is a production technique where three-dimensional objects are built up layer by layer. A digital inventory reduces the need for physical inventory, saving time and money. Norway’s Korall Engineering automates product design and optimize parts for 3D printing using artificial intelligence to improve functionality, reduce lead-time, material waste and production cost.Sol Clarity USA has developed a technology that can keep Solar panels clean autonomously without water, abrasion, moving parts, or manual labor.SurplusMap Norway geospatial analytics to find ideal sites where it is possible to take advantage of renewable energy infrastructure.
