      the technology that I am working on currently is very expensive. it is called Power-to-Gas which uses electricity to break down water to hydrogen and oxygen.
      In my masters, I worked on plasma flame to break down biomass. It was also an expensive technology.

      I once needed to use a special microscope called a Transmission Electron Microscope to look at the catalyst I made to try to understand how it worked. These instruments are very expensive and cost over €1 million.

      A 3D printer for metal can cost €0.5 million too.
