They’re all too yellow to admit that none of this will deliver enough energy in their lifetimes, if ever at all.

Germany and Norway reach blue hydrogen agreement – Germany’s RWE and Norway’s Equinor have agreed to supply Germany with low-emissions hydrogen fuel. The long-term plan is to provide 100% cleanly sourced green hydrogen.

What is blue hydrogen? For years, the prospect of clean hydrogen fuel — which emits mostly water vapor when burned — has excited those hoping to abandon fossil fuels.

However, the production of completely clean “green” hydrogen, which is separated from water with power generated by clean renewables such as solar and wind, is not currently viable at a large scale.

The alternative “blue” hydrogen, which is produced by burning gas, remains a cheaper option and aims to capture and store more than 95% of emissions.
