The evolution to a more digital and carbon-free grid and industry will continue.

In most locations, however, green hydrogen is still two to three times more expensive than blue hydrogen.

Germany needs to meet a target of renewable energy sources contributing at least 65% of power output in 2030 as part of the country’s overall goal to cut CO2 emissions by at least 55% compared with 1990 levels by that date.

Existing nuclear technology could already produce hydrogen at below USD2 per kg, and a new generation of advanced small modular reactors could achieve the 90 cents per kg target price potentially by 2030.

A hydrogen strategy, due in Q1 or Q2 this year, avoids the UK becoming "a wonderful R&D hub with multibillion-dollar industries created elsewhere,"

In 2020, Germany installed 1,431 MW of new onshore wind capacity (+46%), raising the total installed onshore wind capacity to 54.9 GW

Global hydrogen demand is currently dominated by the refining and ammonia production industries that primarily use natural gas as a feedstock.

Abu Dhabi National Oil Co (Adnoc) formed an alliance with Mubadala Investment Co and ADQ to produce hydrogen from renewable energy, known as green hydrogen,

Located at the heart of Total's La Mède biorefinery and powered by solar farms with a total capacity of more than 100 MW, the 40 MW electrolyser will produce 5 tonnes of green hydrogen per day to meet the needs of the biofuel production process at Total's La Mède biorefinery, avoiding 15,000 tonnes of CO2 emissions per year.

The US Energy Department has a Geothermal Technologies Office and they are understandably optimistic.
