Is "power to H2 to power" really a solution ?

Last June 4th,  German minister of Economy (Peter Altmaier) has announced a massive 9B€ investment in the "Renewable Hydrogen (RH2)" value chain. He wants Germany to become the world leader in the green H2 business. 



How to explain this move? is it realistic? and if yes for what use cases?
Let's try to understand the driving forces, benefits and costs.
Di-Hydrogen (H2) is a gaz and does rarely exist in its pure form. It is therefore obtained from its compound through carbonized method (70% of today produced hydrogen ), biochemical conversion and through electrolysis of H2O (source Hydrogen Europe platform):

It is mostly used in industry (50 % in Refineries, 45 %for Ammonia-based fertilizers production, and 5% for other needs such as electricity generation) - Source IEA
Di-Hydrogen carry the highest energy content in weight (compare to common fuels) but the lowest in volume. To concentrate the energy stored per volume unit, several methods can be used. The most common on…

Plasticity – Flexibility – Resiliency

Well, this all started well. 
(french version below)
Géry and I had to leave in 20 days to cross the USA with our bike, to meet those who are working to find solutions, alternatives, new ways to live in harmony on this planet.
COVID 19 has caused us to revise our plans.  No possible plane for Géry, no solar-bike for me, no hotels or campground available, and no possibility for meeting with all those problem solvers.  So, it was a bit "should I stay, or should I go now"?
We both decided to go together but separately.  We are going to travel two continents at the same time: America and Europe.  Some would see it as greed, we see resiliency.
Having lost my co-driver and the "superbike", I turned to what was "close to me" (short circuit ;-): my son Léopold (21 years old) and my everyday bike.

We will be leaving next week, with a sum of compromises that gives, in the end, a rather cheerful cocktail.  My wife Corine will accompany us to provide us with the lodgi…

“Our lives begin to end the day we become silent about things that matter,” MLK

On Monday hundreds of Facebook employees, in rare public criticism of their own company, protested executives’ decision not to do anything about inflammatory posts that President Trump had placed on the giant social media platform over the past week... This news shows that nowadays employees want more and more to take part in the decision of their company. Isabelle Ferreras (see the last post of Gery) has recently proposed with her colleagues around the world a manifesto called  "Work: Democratize, Decomodify, Remediate". She states that working humans are so much more than "resources" and that firms must be democratized.

How? By involving employees in a decision relating to their lives and futures in the workplace.

Why? Simply because without employee no chances of success for the employer as they are the core constituency of the firm. But today, employees are mostly excluded from participating in the government of their workplaces - a right monopolized by capi…
