Image: Empa In future, commercial vehicles will not only have to emit less CO2 but also meet stricter exhaust emission limits. Many experts expect that this could herald the end for fossil diesel. One possible alternative is dimethyl ether: The highly volatile substance burns very cleanly and can be produced from renewable energy. Empa is investigating this new powertrain concept using a special test engine. The energy requirements of long-distance trucks can hardly be covered by batteries. Combustion engines are difficult to replace in this case.
