Something is brewing in the financial world. “Sustainable finance” and the growth of ESG funds have been taking the market by storm in recent years. Since most major PV projects end up needing investors from the capital market, it is only a matter of time before they will have to adapt. The beginning of March 2021 saw a milestone reached in this process.

In the UK, British Airways has invested in hydrogen-electric aircraft developer ZeroAvia with a focus on hydrogen-electric power solutions for 50-plus-seat aircraft. In Brazil, Petrobras has joined forces with Siemens to develop green hydrogen solutions. In Portugal, the government and the European Investment Bank signed a non-binding memorandum of understanding for hydrogen cooperation.
