Dangerous hydrogen might be part of the solution of future energy supply!
Don't forget the Hindenburg Disaster of 1937!
Global Warming is a hoax and Climate Change is a religion.
Heavy Big Government socialist interventions are needed! Do we want that?
"In recent years, more than 60 countries have developed strategies to stimulate the market ramp-up of hydrogen, particularly in the industrial sector. However, in 2023, less than ten percent of the originally announced green hydrogen production was realised ...
The two researchers therefore recommend using demand-side instruments such as binding quotas to channel green hydrogen specifically into sectors that are difficult to electrify, such as aviation, steel or chemicals. For example, according to an EU regulation, 1.2 percent of all aviation fuels must be blended with synthetic fuels based on hydrogen from 2030. This quota is set to rise to 35 percent by 2050. ..."

From the abstract:
"Green hydrogen is critical for decarbonizing hard-to-electrify sectors, but it faces high costs and investment risks. Here we define and quantify the green hydrogen ambition and implementation gap, showing that meeting hydrogen expectations will remain challenging despite surging announcements of projects and subsidies. Tracking 190 projects over 3 years, we identify a wide 2023 implementation gap with only 7% of global capacity announcements finished on schedule.
In contrast, the 2030 ambition gap towards 1.5 °C scenarios has been gradually closing as the announced project pipeline has nearly tripled to 422 GW within 3 years. However, we estimate that, without carbon pricing, realizing all these projects would require global subsidies of US$1.3 trillion (US$0.8–2.6 trillion range), far exceeding announced subsidies. Given past and future implementation gaps, policymakers must prepare for prolonged green hydrogen scarcity. Policy support needs to secure hydrogen investments, but should focus on applications where hydrogen is indispensable."
