Carbon Sources & Sinks

By
By not distinguishing between a fact and an opinion, by dint of confusing orders of magnitude and time scales, I wanted to find the large masses of carbon production and carbon sinks and share them here. We have included in the site under the "fact" tab the data we found in "the Project Drawdown - March 2020" and which states, by order of magnitude:   Carbon sources 1.       Electricity production                : 25% 2.       Cultivation & agriculture         : 24% 3.       Industry                                     : 21% 4.       Transportation                         : 14% 5.       Building                                    :    6% 6.       Rest                                           : 10%   Carbon sinks 1.       Land                                           : 24% 2.       The oceans                                : 17% 3.       The Atmosphere                        : 59%   What about taking another source: the book of Bill Gates, "How to avoid a

Hydrogen fuel cartridge .. let's power bikes ?

By
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

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
