I saw somewhere (here in fact: https://www.dailymail.co.uk/news/article-9805555/Motorway-speed-limit-cut-60mph-reduce-illegally-nitrogen-dioxide-emissions.html look for the blue box on the right about halfway down) that they're going to trial a section of road with overhead lines for electric lorries with pantographs similar to railway locomotives. Given that the overhead lines on railways come down on occasion, causing utter chaos, it strikes me that hydrogen powered HGV's would be a far better alternative. One plus though, this electric system could keep all the lorries in lane one, leaving lanes 2, 3 and 4 for the rest of us 🙂
