Hydrogen’s bad news

Things hasn’t been the most positive for hydrogen the past 2 years or so. Hyzon Motor is on the verge of ‘giving up’, while When one look back, it is a wonder why we felt comfortable ignoring some of the bigger problems associated with hydrogen. It is definitely less ‘trendy’ to tout hydrogen as the solution for the energy transition these days.

One of the challenge about the climate and energy transition is that it is a transition. And that means there is going to be change happening over time; and the challenge is that we don’t really know what the end point is in terms of the technology and pathways even when we know that we’re trying to have a go at net zero.

In the meantime, as we struggle to determine what we’ll use to fuel our aircrafts or vessels, we are making decisions on replacing these equipment, and trying to project cashflows over an asset lifespan or 20-30 years. These all without the certainty of the fuel being available is extremely challenging. So instead, we are more likely to bet on things not changing rather than things changing.

Hydrogen continues to face an uphill battle when it comes to the science, the technology and economics. But there is still good reasons for us to continue refining the technology we have. In the mean time, while we are still trying to decarbonise what we can, we try to leverage the resources that are available more immediately. We can optimise our biofuel supply chains more to achieve lower carbon intensity. Along that journey, we can improve our traceability of feedstocks and biofuel supply chains.

Now, biofuels or any of the new fuels will never be as ‘cheap’ as fossil fuel. And just because they are chemically almost equivalent to the hydrocarbons we dig from the ground doesn’t mean they are the same. This means we will have to continue working at pricing carbon and allowing the real price of carbon to hit all of us. Governments can protect the economically vulnerable not by blocking the transition but ensuring that more and more of that carbon revenues gets directed to support the vulnerable who may not be able to deal with the cost from the transition.

Biofuels could even be a commercialisation pathway for green hydrogen as the hydrogen can contribute to boosting the biofuel yields of organic feedstocks in the FT-Gasification pathway and improve the overall economics of the project when there is access to cheap renewable electricity. It’s almost like blending e-fuels into the mix already. This is a plausible intermediate step for us to encourage more green hydrogen production to sufficiently create more scale to bring down the costs.

The technology surrounding logistics for hydrogen then needs to improve before the end-use equipment would transform. Changing end-use equipment is still the hardest to do. Even if it’s just the heavy industrial users who have to change.

So the good news is that we may still eventually land on hydrogen in some shape or form. It may not be what we are envisioning now, but it’s vital to recognise that the time horizon is probably a lot more stretched out than we think.

Reframing our relationship with earth

This ad campaign by Activista, mainly targeting Space X on Earth day – I believe that was in 2021 – is brilliant. It helps to put things into perspective in terms of how we approach our resources and earth.

The message still rings true today and in many ways, it is saying something about the human heart. Our wandering heart often wants to look for something else to sustain ourselves. Something else that may not be designed to sustain us, but we want to make it what our lives depend upon.

Yes, as a Christian, I’m talking about Christ, who provides the salvation we need when we are wandering about seeking salvation through our work, relationships and other forms of addiction in our lives.

Significance of work

What does a job mean for you? What is work to you?

It used to be just tasks or collection of tasks that had to be done. The tasks were easily connected to the end goals.

Then things got complex and the tasks were clear but it felt more distant from the ultimate outcomes that the whole lot of people were trying to achieve.

Finally we did away with task-based identification of the work and changed parts of the work to be based on creating some kind of outcomes. In trying to connect the outcomes to the person, we lost the clarity on the specific tasks required. That can lead to undisciplined exhaustion of energies and burn out.

On the other hand, for all the jobs where tasks can be clearly specified, technology has been used to displace human workers. Leaving humans to only supervise or check through the results. In fact, at some point even the quality checks can be automated.

Where does that leave us? What does that mean about the future of work?

The future of work can be meaningful if we resume our human role of caring for who the outcome of work is for, and the manner in which the work is done. We carve out that higher role for ourselves by being capable of continuous improvement that focuses on the final objective of the work itself – the satisfaction of the user.

AI Roadmap

Everything that has become a norm in our lives went through some hype cycle. So in essence people may overblow its usefulness and think these things are going to change the world but then it doesn’t change the world overnight so things comes crashing down for a while before it goes on to slowly change the world. The internet is probably the best example. In the 90s people were sure that the internet was going to change everything, and so it went through a bit of a hype. So did computers in the 80s. But after the hype, things crashed, and then life went on except it got changed bit by bit, steadily and surely.

Generative AI is itself going through a bit of that; we are all sure things are going to turn out great. Of course, some doomsayers will be warning the world of the problems and calamity it would bring – just as Socrates thought writing was a poor form of communication and would also bring about the decline in memory of men. I think it is probably necessary to create more safeguards for AI and allow the governance to evolve with its development.

I think Gen AI will be helping to augment the capabilities of human workers for a really long time before they come to ‘replace’ workers so to speak. Yes of course you could use some kind of AI technology to help you even have a conversation at the call center, but it’s not going to be able to handle 100% of the queries, you will eventually still have a human in place. Consultants for example, who might have been spending time copy-pasting or doing data entry type of work might lose their jobs but then there will still be someone senior who needs to intervene.

The real economic challenge for us is how are we going to let Gen AI do the so-called low-level jobs while maintaining a pathway for us to train more junior workers into capable senior workers. Sure there is the grunt work that has to be done but traditionally, the juniors learn the ropes by doing those work. If they are going to be performed by Gen AI, then how on earth are they going to be able to get the chance to learn?

There is still substantial job opportunities which are slightly underpaid but cannot be replaced by Gen AI. These work are underpaid either because of systematic biases in the economic systems or as a function of labour market rigidities. They include the care-giving, pastoral guidance type of roles, as well as all of the cases where it is important to have a human example who can model moral character and other crucial human attributes. No kid is going to see the politeness of a Gen AI figure or speech bot and say he or she wants to be courteous because they are a role model for the kid.

To me, those problems will need to be gradually resolved before we would allow AI to play a bigger part in the lives of people. Part of the way some of these problems are resolved is actually through mutual cancellation with the demographic transition challenge. Economies that are mature and have severely ageing population will need to rely on AI for many things. Improving labour mobility globally should slow down the need for that but it is inevitable for these markets who have the resources to play the early adopters’ role.

Single pivot point

To make a change, we need a single pivot point each time. The pivot point is where things are fixed in place and do not change, and all the other changes hinge on it. And then when we make the next change, we can have another pivot point. But with any one change, we need to select a point of invariance to ensure some kind of order for the change.

In our climate transition today, too many people are trying to change things without a pivot point, thinking that the whole world has to transform. Determining what can be kept constant first is probably a good way to use consensus to drive actions. Then you’ll begin to realise what you are trying to keep the same can have far reaching consequences. For example, if you want to keep energy demand constant and start switching out existing demand into renewables, then you’re making it difficult for economic activities to expand. If you want to keep energy cost constant, then you risk keeping things to status quo and banishing adoption of costlier but greener technologies.

Laying out the trade-offs matter but one can consider how we fix certain parameters and move others first before coming back to revisit these. Take energy costs for example; given the cost of living issues and challenges, governments might want to focus on expanding proven, existing low cost green energy sources and pushing through all manner of regulations, and coordination necessary. Capture of landfill gas to be upgraded into biomethane and upgrading the biogas produced in wastewater treatment plants are low-cost sources of renewable gas that can be plugged into the existing system to displace fossil fuels. Malabar’s biomethane injection plant has just received the Greenpower certification and is the first biomethane plant in Australia to do so, ushering in what we hope to see as an era of using market mechanisms to drive renewable gas and fuel growth as it had done so for renewable electricity in the past decade in Australia.

Some may argue that prolongs the life of fossil infrastructure but we are calling them fossil infrastructure only because they are majority driven by fossil fuels as a result of legacy. One day, those infrastructure could be 100% driving renewable fuels.

Pathway to Hydrogen

I keep thinking about the role hydrogen would play in the netzero energy system. It is important because most specialists in the field think it will be incredibly important. But I’m afraid some of them think of the importance not from an energy or thermodynamics perspective but from a technological, socio-economic perspective. I think that is misguided for something that is so nascent and imature.

The solar and battery learning curves cannot be used to project what happens to hydrogen because it is fundamentally a more complex type of project. A lot less plug-and-play compared to solar panels or batteries. For solar panels, the technology takes in light and transform it into power, which in essence is the flow of electrons. There is of course the issue of DC power versus AC power but the inverters will deal with that translation; and you can plug directly to existing electricity grids. Of course, when you have a lot of them the grid must start shifting but at least you get a shot at getting started. And after that you’ve got batteries coming in, again almost ready to work with the existing electrical infrastructure.

Green hydrogen production integrates with the electricity system fine as well; it takes in power, feeds the electrolyser which separates pure water into oxygen and hydrogen, storing away the gas as it is being produced. However, the most valuable output in the process, the hydrogen, needs to be properly stored and transported to where it is needed. And all of these infrastructure do not yet exists! The largest part of the revenue generation problem has not been sorted!

This is why it is so difficult to get hydrogen started, and so expensive to do so even when the technology seem more and more established. The challenge is that a lot of that infrastructure would also serve some of the current fossil gas interests. There are issues of couse with the risks of interest conflicts when the fossil industry push for hydrogen.

The fact that hydrogen is not so plug-and-play to our current system means more evolution is needed before we are ready. Instead of putting direct incentives into hydrogen production, we should be using our resources to solve the problems along the journey to the hydrogen future. A lot of these problems involves collective action, coordination of choices and displacement of swarthe of economic activities that requires proper thought about restructuring.

There is really much more work to do than administering incentives. And this is definitely not an area the government can easily rely on market incentives to accomplish.

Transition economics

What happens in economics when technological innovation happens? There’s a bit of dilemma between technological progress and economics because technology needs to progress to a stage when it upend the economics of an established technology – yet the incumbent is often enjoying scale economies as well as other effects such as network economies that can make it incredibly difficult for the new comer even if it is superior to existing technology at the scale that the incumbent operates.

In the Innovators’ Dilemma, that was being described and the strategy as well as the market approach is always for the new technology to chip away at the market of the incumbent technology by being appealing enough to a small group in the market to help it grow its scale and challenge the incumbent on more fronts gradually. Can the new technologies that we are trying to cross over towards make their way through this path in order to break the dominance of the incumbent technologies?

They probably won’t be able to move fast enough. And that is probably the justification for government to intervene and encourage developments. Yet governments do not want to be seen as favouring particular technologies. There is also a concern about creating inefficiencies in the market by distorting prices or forcing the taxpayers to shoulder the wrong costs.

Yet in reality, for the world to create a better future, there’s no real ways around it. The modern world was not built by shielding taxpayers from the wrong technological investments nor from carefully betting on the right technologies to take off. The complex problems around climate issues today are not so different from the public infrastructure challenges that people faced in the time before government had the kind of powers they have today. They are more complex, and we probably need more talented people working on them, both in the private sector as well as in government. In fact more so in government than ever.

The challenge remains the cost-benefit paradigms and all the free-market type principles to government and what intervention should be like. Without more mission-oriented policy-making principles and a system that is properly leveraging talents and passion, it will be difficult for governments around the world to assume the kind of role and leadership it needs to lead the transition.

Profitable transition

What does it mean if companies declare that they are committed to the energy transition including committing resources towards it, and massive investments, only to make a U-turn when oil & gas turns out to be way more profitable? It tells you that it had always been about the money it makes rather than the transition. Never mind that the fossil fuels continue to drive up carbon emissions and hurting the climate. In fact, maybe climate change would drive up demand for energy – especially in terms of heating or cooling, or requiring more activities in the economy to deal with and mitigate the impacts.

Can the work of accelerating the energy transition be left to the markets? Can profits really motivate companies to support the transition and reduce carbon emissions? Does the market demand understand, appreciate and would be willing to drive and pay for the transition? I don’t think so. Absent regulation, it is unlikely for the markets to drive the emergence of the solution. It is as if we want seat belt manufacturers to drive the messaging around safety and benefits of having seat belts rather than legislate it as a requirement in cars. Or just waiting around for cars to adopt them as the standard feature in a car.

We probably don’t have enough time for all that to make an impact on mitigating climate change. Regulations will be required. To put a price for carbon on the market, to push technologies and options in the market that will reduce emissions. We must also evolve and steer the regulation as our understanding of the technologies and impact on environment advances. We don’t have to get everything right on the first try but we do need to be trying.

Bringing my writings together

Probably for the first time in the history of my personal blogging, I’ve brought together all my writings under a single site. Since migrating kevlow.com to a self-hosted platform (though you probably won’t be able to tell), I’ve pulled in some of the even older pieces of writing I’ve put out on the internet. This includes blog entries written from as far back as 2005.

Looking through my entries, there was the period of 2011-2013 when I wasn’t so active probably because I was busy in LSE. It was probably a bit of a shame because those were some really formative years as well in terms of the development of my academic thinking and also integration of my faith into my intellectual identity. Perhaps I had wanted to keep things a bit more private. I would like to point out that those were also years when Tim Keller’s writings engaged my mind so much more.

The focus of my writings has certainly evolved significantly especially with the addition of topics around energy and climate. My passion for education and learning was more dominant earlier in my writing though I wouldn’t consider it to have died down from then. My interest in other topics had expanded.

I could have continued to keep my writings in different niches and have them separate but I realised that in some sense, they were reinforcing one another and were all products of my principles and conviction that drove me. After years of refinement, my conviction is still towards this broader theme of trying to create a future that we all want to live in. Whether it’s energy, education, sustainability or economic development, I am future-oriented and all for investing in what is to come.
