Hydrogen fuel cartridge .. let's power bikes ?

As "green" hydrogen production and storage has become an EU green deal central strategic axis, more and more innovative solutions emerge from academic and industrial players. Early this month, the Fraunhofer institute published an article presenting a prototype of what we can call "hydrogen power paste": hydrogen power paste (source : Fraunhofer institute) The principle behind is to create a magnesium hydride paste (whereas a high quantity of hydrogen is stored). When water is added to the mix, hydrogen gas is produced and can be used in a fuel cell to create electricity.  In the previously published article describing hydrogen fuel principles and applications, we mentioned that this H2 energy source was particularly suited for heavy transportation such as trains, trucks, or boats. This power paste concept is particularly interesting for light mobility or applications where there are no refill stations neither H2 storage tanks easily available. One can think of Hyd

Let's make Europe an adventure again

Gery and I are back on the road this year 2021 for an electro-solar race.  One more name to be added to the list of the Green Deal.  We have our  circular economy plan . Let me explain: the  plan  is the map here above; the  economy  implies that we are going to recharge our batteries with solar energy that we will self-produce and  circular  because we are simply going all the way around Europe.   Even better, we will leave Brussels in June 2021, in the presence of Frans Timmermans, Vice-President of the European Commission, in charge of the Green Deal.   We will have less than 60 days to complete this tour of Europe which will pass through 33 countries (to be confirmed), will total 10,000 km and will have 5 checkpoints (Stockholm-Sweden, Constanta-Romania, Passo Stelvio-Italy, Pico Veleta-Spain, Porto-Portugal) with an expected arrival in Lyon.   Portugal will be our "far west" stage and we are so pleased that this country has decided to commit itself fully to the energy
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.

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
