Next Generation Energy Technologies

Last year, over 1000 projects were submitted to the European Clean Hydrogen Alliance (ECH2A) pipeline and as the map shows, Estonian stakeholders were very active from production to consumption. This was further bolstered by the Estonian hydrogen IPCEI (Important Projects of Common European Interest) submissions.
A unique chance to witness next generation technology in Tallinn’s Seaplane harbour marina, the Energy Observer. This catamaran is the first hydrogen vessel in the world. Hydrogen is produced on-board from renewable solar, wind and hydro energy. Hydrogen is used as fuel directly on windless days or late hours without sunlight.
On the 30th of May, Estonian based SKYCORP OÜ with the Estonian Hydrogen Association presented in Tallinn Europe’s first commercially available hydrogen drone, the e-Drone Zero.
The next generation hydrogen Fuel Cell technology used on the drone allows it to have a flight endurance of 120 minutes instead of the usual 20-30 minutes as seen on batteries. It dramatically increases the value from drone missions and opens up new use-cases especially with future Smart Cities. Additional benefits include refuelling in just 1-2 minutes to increase productivity without having to carry multiple sets of LiPO batteries around.
