Is Green Hydrogen Being Overhyped?

Plenty of talk but not very much action, it seems. The author notes that ‘the small size of hydrogen molecules poses safety and greenhouse gas-related risks that must be mitigated’, while most current gas grids can’t cope with more than 20% hydrogen content anyway. Affordability looks at least questionable. Such issues will require years of effort and expense to even attempt to get to grips with.

The global discourse on addressing climate change, energy transition, and investments is currently dominated by the topic of green hydrogen, says Dr. Cyril Widdershoven @ OilPrice.com.

The media frenzy surrounding the expanding array of projects, subsidy schemes, and international strategies is fueled by the influence of Washington’s IRA plans and the EU’s energy strategic projects.

It appears as if the choice for a post-hydrocarbon world has already been made, with green hydrogen or its derivative, green ammonia, emerging as the favored options. Western parties remain highly optimistic, as large-scale renewable energy initiatives are closely tied to these alternatives.

However, it is crucial to bring realism into the discussion. This aspect should be addressed sooner rather than later.

During the Qatar Economic Forum in Doha, Saudi Ministry of Energy Abdulaziz bin Salman highlighted the skepticism, stating, “People talk about hydrogen as the fuel of the future… but who is going to be the offtaker?”

Abdulaziz bin Salman emphasized that hydrogen lacks a clear market price, which inhibits its development. He questioned the prevailing discussions on various types of hydrogen, such as blue, green, purple, or pink, by emphasizing the need for identified offtakers and clear policies in this regard.

Amin Nasser, CEO of Saudi Aramco, previously stated that blue hydrogen costs $250 per barrel of oil equivalent (boe), which suggests that customers in the EU, Japan, or South Korea would not be willing to procure it at such prices.

Additionally, Bloomberg reported that despite the exponential growth of the green hydrogen project list, investors remain unconvinced about financing them.

Currently, there is a proliferation of hydrogen projects being proposed, but only a mere 7% of them have secured financing to commence construction. Bloomberg New Energy Finance has highlighted that this financing reality sharply contradicts the expectations set by the IRA and EU strategic plans.

Financial institutions remain highly skeptical about the feasibility of economically and affordably producing large volumes of green hydrogen.

According to some industry insiders who spoke to Bloomberg, while there are numerous project announcements, very few are actually being realized on the ground.

The Climate Crisis Of 1896

Tens of millions of people died around the world during 1896 from heat, drought, fires, tornadoes and floods. Atmospheric carbon dioxide levels were below 300 PPM, which climatologists say is very safe.

BOOK REVIEW:  Climate Uncertainty and Risk – Rethinking Our Response

Book Review by Kip Hansen – 26 May 2023

There are a great many books about the Climate Crisis, the Climate Emergency, the Climate Problem and the Climate Issue – along with its myriad policy solutions—for and against.   Amazon returns “over 50,000 results” for books about “climate change”.  The authors range from politicians through teen-aged activists, economists, geologists, lawyers and assorted “tinkers, tailors, soldiers and spies”.

There is one book that is far different, with a difference that is important.  It has been written by a climate scientist.  Not just an academic climate lecturer, not just an academic climate researcher, but a truly professional climate scientist who has made her living doing climate science across the entire gamut of the field.  She has been a climate science student, a climate science professor, a climate science researcher, the head of the atmospheric sciences department of a major university and is co-owner of Climate Forecast Applications Network (CFAN) which actively supplies real-time, real-world actionable weather and climate forecasts to clients around the world, helping them prepare for and take advantage of ever-changing weather and climate conditions.  

This author, Dr. Judith Curry, does not just plug numbers into computers and write papers for the journals. She does climate science,  in support of  clients, helping them to make better policy and action choices.  She is a working professional climate scientist, working in the trenches of the field where real people live, where real people need to know what to expect from the weather and climate in order to grow their crops, raise their children, defend against floods and droughts, and prepare for the never-quite-certain future. 

This new book, Climate Uncertainty and Risk — Rethinking Our Response, is truly enlightening.  The world has been solely focused on the risks associated with the Earth’s changing climate and has settled on an almost-exclusive solution—eliminate the use of fossils fuels to reduce atmospheric Greenhouse Gas Concentrations—despite overwhelming evidence that the nearly everything leading to that solution, all of the data and all of our combined understanding is highly uncertain, ambiguous, vague and distinctly unsettled.  Worse, much of what we would need to know to make the current policies appropriate may be simply unknowable.

The problem thus becomes “How do we make decisions about how to deal with the uncertainties presented by changing climate?  How do we formulate sensible and reasonable local, regional, national and international policies despite the uncertainties?  — policies that we as a species will not regret 50 years from now?”

Uncertainty is a terrific burden when we feel that “something must be done”.  All of us sometimes face this kind of pressure in our daily lives – we have to do something, the situation seems intolerable, but both the situation itself and possible solutions are filled with uncertainties.  Adding to that unsettling uncertainty can be the uncertainty regarding the very existence of the situation itself—is there really a problem? Or does it only seem to be so?

Regardless of where you currently find yourself on the broad spectrum of opinions (and, we can all admit, biases) about the climate issue, you will find this book will help to clarify the intellectual and informational terrain of the field, bringing into focus many of the issues you are already somewhat familiar with and, more importantly, bringing into focus many issues and facets of the broader climate policy decision-space that you may not have even been aware existed.

If you are certain in your view of present and future climate, certain in regards to what are and are not appropriate policy for solutions, abatement and adaption, you need to read this book.  This book is the cure for your ailment.

If you are mystified by the swirl of conflicting opinions and ‘facts’ presented by those who all appear to be highly qualified experts in the field, if much of the data about climate seems to contradict itself, then you have met the Uncertainty Monster.  Reading this book will help to vanquish the Monster aspect, and supply you with potential approaches to dealing with the ever-present uncertainties.

The lessons to be learned from this book apply not only to climate, not only to science, not only to national and international decision and policy-making, but to all aspects of life, which is itself, at all times, highly uncertain. 

Bottom Line:

Very Highly Recommended.  A book not to be missed by anyone whose interests include any of the sciences.  You will have been amply repaid for the purchase cost and the time invested by reading even one of the sections and chapters of this truly enlightening book. 

Don’t expect this book to magically eliminate the uncertainties of the Climate Issue—uncertainty is at the heart of it.  And that’s a very important lesson to learn.
