Hydrogen is the most widespread element in nature, found in everything from the ocean depths to the air we breathe, in every earthly substance and in stardust. Hydrogen is the foundation stone of the universe. In terms of energy, its applications are widespread, including fuel cells, industry and space. It's hydrogen that launches into orbit satellites, space stations, monitors, telecommunications systems and probes destined to fly about for decades.

Eni, Toyota and the city council of Venice have agreed to assess whether they can build a service station for filling vehicles powered by hydrogen. The site for the new plant will be chosen soon, and our eye is on Bavaria, where hydrogen cars are making great headway.

This will intensify pressure on moderate Senate Republicans to join Democrats in calling for Bolton and other direct witnesses to the President's conduct to testify under oath in the impeachment trial. This may also provide an opening for Democrats to lobby Chief Justice John Roberts – who is presiding over the Senate trial – to subpoena Bolton himself.
