So it's pretty recent but it's been on a steady upward trajectory worldwide. Since then but more interesting perhaps is the geography of these searches. Denmark is far and away the country with the most search activity around green hydrogen more than double the next country according to google. The top ten is rounded out with in order nepal united arab emirates australia singapore new zealand oman norway the uk and canada. The us is number twelve in case you are wondering so setting aside nepal for a second. Maybe somebody can explain what's going on and hydrogen in nepal to me but apart from that the list basically makes sense. I think you could basically group. The country's into three categories. The first group is europe and especially northern europe which is home to i think the most early government support for green hydrogen and where the market indeed may actually take off i.
