Demystifying Green Hydrogen

Green hydrogen is made using electricity from renewable energy to electrolyze water, separating the hydrogen and oxygen atoms. It's a clean alternative to fossil fuels that, unlike traditional renewables like solar and wind energy, can be stored and used at any time of day, in any weather condition. It also may be the only way to bring greenhouse gas emissions from the power sector to the equivalent of zero, considering several countries' commitment to carbon neutrality over the next 20-40 years. As the impacts of climate change become more visible around the world, green hydrogen is a promising clean energy alternative, and the total hydrogen market is expected to be worth $2.5 trillion by 2050.
However, it is currently more expensive to make renewable hydrogen (RH2) gas than the wind or solar used to create it. It is estimated that in power generation for heavy industry, using green hydrogen could today increase costs 200-800 percent.
What are the hurdles to more broadly deploying green hydrogen? Is it facing a similar situation to that of wind and solar energy a decade ago? Can the world really depend on green hydrogen to drastically bring down its carbon emissions and address climate change?
The Center on Global Energy Policy and Columbia University's Santiago Global Center hosted a panel of experts for a discussion on these issues.
Moderator:
-- Laurie Fitzmaurice, Executive Director, Center on Global Energy Policy at Columbia University SIPA
Panelists:
-- Juan Carlos Jobet, Minister of Energy, Chile
-- Dr. Julio S. Friedmann, Senior Research Scholar, Center on Global Energy Policy at Columbia University SIPA
-- Eric Guter, VP & GM - Americas Growth Platforms, Air Products and Chemicals, Inc.

Took a drink every time he said right. I'm dead now.

Leveraging tribal interest thanks

[@belensilva4221]

That was so interesting!! I will be looking forward to part 2! Thank you all for this!!

[@safetybay4345]

Excellent presentation, thank you to all the presenters for your well -edited, elucidating responses on such broad topics.

[@matthieubonnard2702]

Politics, academia and business perspectives combined. What an intellectual pleasure and a great educating moment. Thank you

[@Ionic_Projection]

Thank you so incredibly much, for this being free and open to all. And for all of your levels of mastery in these subjects pertaining to things i'm incredibly passionate about and one day look forward to working with each one of you Particularly Julio and Eric! I was like literally talking along with you guys lol like I was there hahah

Wow

[@patrickdnyc4129]

Superb presentation and discussion. Thank you.

Why we need to depend on NH3 fuel CELL when the hydrogen fuel CELL will takesbplace atvfirst priority...correct me if iam wrong

[@rabmcnair4488]

I don't get how green hydrogen will help reduce climate change.
From my understanding when you burn hydrogen gas in air it produces water vapour and nitrogen oxides. It is also my understanding that water vapour is a greenhouse gas and it could be argued that it is causing more harm than CO2.

Muy interesante.
Las grandes potencias tendrán que meditar si están dispuestos a invertir esos billones de dólares o el planeta se va al despeñadero.

I've been a big fan of hydrogen for a long time, but only Green hydrogen

[@gregpackerpacker7293]

Madam in reference to you conversation on green hydrogen. We are designers inventors of all types of technology. Over 30 yrs working on hydrogen,I would have to say we have the only system in the World that actually re-uses the hydrogen over and over again,producing a huge excess of electrical energy.As well our system produces "ZERO" CO2,The way the whole World is going about this is all wrong.Our system does not have to stop to re-fuel,and can be used to run Tankers ,mining equipment ,planes etc.This technology eliminates all existing sources of Renewable.

Short term year 2021: Limit Carbon emissions, lower costs and strategic roadmaps and industry alliances. Long term years 2022 and beyond: Positive outlook to replace fossil fuels with green hydrogen by 2050.
