- Learn about hydrogen production and carbon intensity in this Hyfindr Tech Talk. Steven and Greg discuss the various ways of producing hydrogen including electrolysis, steam methane reforming, nuclear power and coal gasification. Steam Methane Reforming (SMR) currently dominates the hydrogen production landscape, accounting for over 95% of hydrogen production. Electrolysis is a developing method, still primarily in the early commercialization phase. These two engineers delve into the steam methane reforming process, emphasizing its two-step reaction system and the use of catalysts to facilitate the reactions.

Executive Summary of Tech Talk Script:
During this Hyfindr Tech Talks, Steven welcomes Greg, a chemical engineering expert and Chief Innovation Officer at BayoTech. Steven and Greg discuss the technology and methods behind hydrogen production and its carbon intensity. Greg expressed his enthusiasm for educating the public about the hydrogen economy and the choices involved in creating a hydrogen-powered mobility system.
There are several methods, many of which have been around for a long time. Electrolysis uses electrons to split hydrogen and oxygen in water, and steam methane reforming, which uses heat to split hydrogen from methane molecules. Nuclear and coal are potential sources of hydrogen through similar processes but noted that coal gasification is less favorable due to its high cost and environmental challenges.
In nuclear power to generate hydrogen, the heat generated by nuclear reactions can be used either to generate electricity for electrolysis or to run a steam methane reformer. Extracting hydrogen directly from nuclear reactions is not common practice.
Steam Methane Reforming (SMR) currently accounts for over 95% of hydrogen production worldwide. Electrolysis, although widely used for other molecules, is still in the early stages of industrialization and commercialization for hydrogen production. The process of steam methane reforming, emphasizing that it involves two chemical reactions. The first step combines natural gas and steam in a high-temperature environment using catalysts to facilitate the reaction.
Throughout the conversation, Greg provided insights into different hydrogen production methods, emphasizing the dominance of steam methane reforming and the emerging potential of electrolysis.

Wauw. This is almost exactly the combination that I and a few prominent Danish chemists started looking into back i 2011,... Mining 'renewable gas' from farms,.. And then hydrogen made from windpower can react with co2 in the 'renewable gas' to substitute natural gas in the gas grid,........and/or the hydrogen used for ammoniaproduction; substituting fertilizer for the farmer. Brilllant stuff,.... have to say your reactor seems groundbreaking!!!,.. Sincerly. Jakob Eriksen.
Great job explaining the operation of small scale hydrogen generators
I believe steam reformation in general consumes lot of movement from one place to another to refine which initially increases the cost. Also you have to maintain very low tempreature if transporting in liquified form and that is why many fuel stations are shutting down considering the cost

This is very interesting. I wish they would give him more time to talk.
We're glad you found the content interesting and will take your suggestion into account for future presentations.
What is best methods of production
Also to produce X amount of Hydrogen from 10 thousand small SMR. Is going to produce more CO2 then produce the same amount of Hydrogen in Larger but less numerous SMR plant . Because more materials that will be required to construct all those plants.
It's one time to be spent for construction, however the small plant will be continuous. Bottom line they need to do a co2e footprint year by year till 20 yrs. It's like cash flow or life cycle calculation
You forgot about Red Hydrogen which Japan has developed to make Hydrogen from the nuclear reaction in the reactor and produced electricity at the same time. So much for experts.
Well. Maybe the japanese forgot to tell the world about it. Experts can't possibly be in the know about all the things other people are producing.... Yet, can you say for sure that the japanese produce hydrogen from the nuclear reaction itself. Or not from the cooling water in their plants?
Why not strip the H2 from the Methane so you have H2 & Solid Carbon NO CO2.
C-Zero is doing this described here... czcams.com/video/IfSfjiH5ZZg/video.html
Sorry dude. You're barking up the wrong tree with hydrogen. Besides the fact that hydrogen combustion engines are a non-starter and hydrogen fuel cell vehicles require precious metalsto be built, and the costs and hazards inherent in compressing, shipping and storing high pressure hydrogen, and the low energy density of anything less than liquid hydrogen... Even if technology manages to overcome all of those drawbacks, the problem remains that the energy cost to refine hydrogen then turn it back into useful electrons to drive a vehicle is at least three times the energy cost to simply charge a BEV battery and use that energy to drive the car. This is dictated by physics and chemistry. No technology can overcome these barriers.
And one more thing. High pressure hydrogen is insidious. It leaks right through metal containers and causes embrittlement of high pressure systems. This means that if the systems are not replaced, an explosion is inevitable. That is the main reason why the very few hydrogen refueling stations that ever existed are either closed or scheduled to close in the near future.
Edit: PS. Steam reforming is NOT green and carbon capture is a fabrication of wishful thinking.
As a matter of fact, I am a genius. The solution is simple and obvious. Use all that electrical power to charge BEVs directly instead of the expensive, dangerous, complicated, indirect route of going through hydrogen as an intermediate step. This is obvious to me, but I'm a genius.@@jaxolotle
Seeing the last statement after finishing my thesis on blue hydrogen production is crazy man😂😂😂
Don't get me wrong, I do believe you
@@emmanuelebong7659 There was a time when I believed that hydrogen fuel cells would be the next greatest thing. Then I looked at the math. So much for that dream.
What I don't know, is the theoretical maximum energy density for batteries. It would be nice to know how much lighter we can expect BEVs to get.
This is just CO2 gymnastics. This will never bring us to a sustainable circular energy system.
Cheap electrity from wind and solar in rural areas!.... Makes all these processes pioneers looked into 40 and 50 years ago feasible. Economically. Indeed desirable.
