Hydrogen: What colour? 19,4 KWh in Li-ion, H2 and NH3 In June, I had the chance to bike with my son Léopold from San Francisco (California) to Denver (Colorado). I planned several meetings with companies dedicated to developing solutions to overcome climate change. That's how I came to meet with Joe Beach, the president of Starfire Energy. From there, I started to learn about hydrogen and ammonia.    First, I realize that hydrogen is so colourful.  You have many different types of hydrogen: the "black," the "green," the "blue," even the "turquoise."   The black : Today, 95% of hydrogen is produced from fossil fuels and is responsible for 800 million tons of CO2 (1.9% of the 43.1 billion tons of CO2 produced in 2019). In 2019, 75 million tons of hydrogen were produced worldwide (one ton of H2 creates 10 tons of CO2).  The technique used is called methane reforming. We take water (2*H2O) and methane (CH4) that we heat, and we obtain after cooki

It must be Atomic !

  After long weeks of absence, I take up the pen again.  The vacations of this summer 2020 were an opportunity to discuss and meet brilliant people with whom I had the chance to exchange on what tomorrow could be like.  I have to write "could" because here, there are no exact sciences anymore, but relatively strong hypotheses. Remember the book  "The limit to growth" in 1972. The book was based on The World3 model, a system dynamics model for computer simulation of interactions between population, industrial growth, food production, and limits in the earth's ecosystems. These hypotheses tell us that the energy mix road will be 35% renewable energy and 65% nuclear energy. However, in Europe (Belgium, France, Germany), we turn away from nuclear power due to a lack of political courage or even the capacity to simply decide.  And yet we have developed all the technology.  What has become of it? The only EPR reactors (European Pressurized Water Reactor) operating are

According to BP's CEO, the fossil fuel consumption peak is now!

  As presented earlier this week by Bernard Looney (B.P. CEO) , we may have reached the liquid oil consumption peak this year. This can be explained by soaring energy demand amid COVID-19 scars, subsequent fossil fuel frozen investments and by increasing renewable energy production capacity at a higher rate than total world energy demand increase. This is the first time a Major oil company integrate officially this trend in it's long term strategic plan, and shift radically from the "business as usual" model.  Full article can be read here   Good news on energy side! Unfortunately, COVID-19 pandemic has disastrous effect on hundred millions inhabitants, especially the poorest ones. 

Les aventuriers solaires au JT de France 3 Bretagne

[Source 19:20 FR3 Bretagne, 23-07-20] Un "tour de France" équipé de panneaux solaires. Ils fournissent deux à cinq fois plus d'énergie que les mollets, selon l’ensoleillement. Intéressant pour monter jusqu'au Mont Saint-Michel... ( Eric Pinault ) [00:09:05 Gery's interview]

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

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 pro

“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
