Arguments for renewable fuels

As part of an assignment for an online course, I developed an article arguing for the role of renewable fuels in the low-carbon economy of the future. I reproduce the full final draft here for my blog readers.

Climate change is a real, global catastrophe that needs urgent and immediate action. 2024 marks the first full year of warming above 1.5 deg C, determined by scientists as the climate change threshold. The Paris agreements were designed to ensure that the long-term average temperatures towards the year 2050 do not exceed this threshold. Breaching this threshold portends irreversible ecosystem damage and more dangerous climate conditions worldwide.

A huge part of climate action involves decarbonising our energy systems, which are responsible for nearly 90% of all anthropogenic carbon emissions. The rapid deployment of wind, solar, hydro, geothermal, and combined with giant battery energy storage systems and pumped hydro energy storage systems, is supporting the decarbonisation of electricity grids and systems. While they are aiming to displace current fossil fuel-based systems, running on fossil coal, oil and gas, there are severe limitations and significant. Only about 20-22% of final energy consumption takes the form of electricity, which means that direct fuel consumption is still the main approach for the consumption of energy.

The solution to this conundrum is renewable fuels; first in the form of biofuels and, subsequently, a combination of biofuels and synthetic fuels produced through various chemical processes, some of which involve renewable electricity as well. Renewable fuels are not transition fuels. They will continue being carriers of energy in the future and serve as an important decarbonisation solution for industries that need to be supported and scaled up.

Renewable fuels are an essential complement to renewable electricity. Not all energy users are served by the electricity grid. The majority of the transport sector, as well as heavy industries, rely on fuels because of mobility or scale requirements. While battery technologies are catching up and have experienced a phenomenal decrease in costs, there are still operational limitations for many use cases. Long-haul heavy transport, due to its energy consumption and mobility, does not lend itself to battery systems. Therefore, even with electrical power production completely decarbonised, significant energy consumption in fuels will still need to be decarbonised. Renewable fuel represents such a solution that will enable low-carbon aviation, maritime transportation, mining and steelmaking to give a few sectors as examples. These sectors are not going away; they will play vital roles in the low-carbon economy of the future.

Renewable fuel contributes to energy resilience and security for countries and industries. Electricity cannot be stored for the long term across seasons except in pumped hydro storage, which requires specific geological features that are not present everywhere. Producing renewable fuels and storing them enables much longer-term energy storage, which can contribute to energy security in times of instability or when supply disruptions occur within the electricity system. This is because fuels are much more stable and transportable, and energy can be released on demand. For example, data centers’ backup power could be a huge battery energy storage system but without an additional source of energy, the batteries would eventually drain down to zero. Renewable fuel can be continuously supplied to the site, and power operations can be operated continuously.

There may be the view that once everything is electrified, only solar, wind and other renewable power generation sources are needed. As mentioned, renewable fuels provide an essential source of energy for mobility and several other sectors that are challenging to electrify and would still require fuel as a backup and for resilience. Moreover, renewable fuels are molecules used not only for energy but also in other chemical industries as chemical feedstocks. Dealing with climate change will require a shift away from fossil-based chemical feedstocks towards low-carbon ones which can be unlock from renewable fuels.

Recognising the role of renewable fuels in the climate transition is just the first step. The next would be to call upon policy actions, advocacy and industrial adoption to ensure the commercial viability. Renewable fuel technologies are available and established. To get to palatable levels of cost for the market, world-scale production needs to be established. That will require industries and energy users to provide unequivocal support for adoption. This is can only be possible with strong policy action to price carbon emissions, mandate blending and adoption; driving demand expansion serves also to expand production and enable economies of scale necessary to make renewable fuels a cost-effective solution for decarbonisation. The low-carbon future is not possible without renewable fuels; and renewable fuels will not enter the equation without policy action.

Low-carbon Hydrogen

I came across a point made by a supporter of low-carbon hydrogen when others were arguing that green hydrogen should be reserved for hard-to-abate sectors, but not for other sectors that can easily decarbonise through a lower-cost pathway instead. The point was that if low-carbon hydrogen was only going to target the hard-to-abate sector, the market size simply isn’t enough to create the scale necessary to drive down the cost of low-carbon hydrogen.

This comes at a time when we are discovering that some of the sectors that could actually pay for low-carbon hydrogen are those with much lower-cost approaches to decarbonisation (for example, food product or food services companies). So why would they be willing to pay higher price for low-carbon hydrogen? Technically, this is where economics starts to break down. Part of the reason is that the end customers are willing to pay – this is especially possible for consumer products where the agrifood industry may be able to differentiate the introduce the food prepared using low-carbon hydrogen. This is exactly what some Seven cafes in Japan is doing.

And to a certain extent, every industry starts out this way; if solar panels were simply looking to the locations with huge energy demand in the day, and also lots of solar resources for power generation, the market is going to be incredibly small. And certainly insufficient to enable the lower cost from economies of scale. So finding use cases and continually expanding them is important. While it might be admirable to keep trying to create premium products and then price it well, the alternative way of getting economics in your favour is actually to keep innovating on use-cases and focus on growing scale in a way that lowers unit cost. This then allows for further expansion of demand and use which improves learning at manufacturing and drives the cost advantage further.

That is the story of China’s manufacturing rise. And Lidar technology is a great example. The original use case for lidar technology was very limited to very specialised fields where great precision was needed in sensing and mapping physical spaces. It was initially used almost exclusively in military applications and would probably have remained so if not for China entering the picture and driving down costs through sheer manufacturing scale. By pushing down prices to particular thresholds, the mass market use case in EVs and other driver-assistance technologies emerges and serves to expand the pool of demand further.

During the hype of low-carbon hydrogen during 2020-2023, people were expecting that the cost of hydrogen production could be pushed down to such levels. Yet if we examine the value chain and recognise that the opportunity cost of using renewable electricity for hydrogen production, we would see that it was difficult for hydrogen production to compete with electrification as a commercially viable approach for decarbonising a lot of low-heat industrial applications.

An alternative path to commercialising low-carbon hydrogen is needed; and it is more about finding other use cases. It could be locations where fuel is needed to run mobile applications, or where transport of liquid fuels were prohibitively expensive and being able to easily produce it make sense. And finally, one of my favourite approach, which I am sure would be the first early commercialisation pathway: colocating green hydrogen facilities with biogas/biomethane production facilities, producing green hydrogen, then use Sabatier reaction (methanation) to produce e-methane, boosting the overall output per unit biogenic feedstock.

Yet even then, it is still necessary to drive costs down in order to be able to produce a product catering to a large and expanding market. Even for that pathway highlighted, the actual demand possible for a single hydrogen project would be limited by the available biogenic carbon dioxide which is limited by the scale of the biofuel/biogas plant. These are all bottlenecks of the renewable industry that needs to be managed. Wind and solar, especially solar is a lot more disconnected from local supply chain and ecosystems in order to pull off a successful project as they are modular and largely plug-and-play. While it means government have less hard work on creating the supply chain, there is less local benefits reaped or job opportunities created from building out solar facilities than if the market starts looking into biofuels and hydrogen.

Ultimately, the economics of hydrogen requires very strong government collaboration and the actual boots-on-the-ground work of creating the supply chain, infrastructure and delivery mechanisms. To tap into some pockets of willingness-to-pay at the moment would help.

Carbon capture

I think there is a place for carbon capture and utilisation. But just not the way we have been thinking or approaching it. Carbon capture and storage in some kind of cavern or project and expecting it to hold on to the carbon dioxide does not make sense. But many other carbon sequestration approaches do: applying biochar to ground, injecting carbon dioxide into cement to strengthen the concrete, or any processes that somehow mineralises carbon dioxide into some kind of other compounds including carbonates.

All of the approaches where carbon dioxide is somehow transform into some other form which is more permanent and serves a function make sense. The technologies involve in terms of filtering the carbon dioxide to a certain level of purity, conveying it and handling it, will play important role in the low-carbon economy.

The reason is that carbon dioxide is still an essential part of many industrial production processes. In any case, the main challenge of climate change isn’t really the presence of carbon dioxide – it is the fact that we are taking out fossil carbon and then turning it into carbon dioxide, releasing it into the atmosphere faster than it can be cycled back into other parts of nature. This build-up of carbon dioxide, strengthens the greenhouse effect, making things really nutty for the climate.

But when we are taking biogenic carbon dioxide and using it, there is nothing wrong because the carbon was sequestered from present carbon dioxide in the atmosphere. Using it merely ‘recycles’ the carbon around. Human systems that does carbon capture can play that same recycling role. Take for example the capture of biogas from the anaerobic breakdown of organic matter. That is a mix of methane and carbon dioxide gas; the carbon dioxide gas can be filtered out and then used for industrial processes, while the pure methane (or biomethane as we call it) can be used for energy purposes – combustion to produce heat and drive turbines to produce electricity.

Moreover, the carbon dioxide produced from combustion can be captured, purified, and utilised just like the carbon dioxide filtered out from the biogas. This carbon dioxide can actually be combined with green hydrogen to form many other hydrocarbon molecules that act as our more familiar fuels that are compatible with many of the engines and systems we have. Not just that, the combusted fuel will emit that same ‘biogenic’ carbon dioxide, which would not count as greenhouse emissions because they are in the short-term cycle. Nevertheless, we can still capture that carbon dioxide and then return it to those uses we talked about.

To me, that’s the role of carbon capture in the future – it is really to recycle the carbon just as nature already does it. It is not to erase the carbon dioxide that has already been emitted. It is really naive to think that spending more energy trying to capture the emitted carbon dioxide can be more worthwhile than using alternative forms of energy that do not emit so much carbon dioxide in the process. That would be the role of these technologies in the future.

Blunomy & bioenergy

My blog has always been relatively free of direct stuff on my work but here’s just a post where I wanted to document some of the work that the Blunomy/Enea team had worked on over the past couple of years.

Moreover, it has been over a year since I stepped up to take care of our Renewable Fuels practice at Blunomy for the Asia Pacific. Things have been really challenging and tough on the energy transition front for the world, and for the business of consulting but when I look at these analysis and work we’ve put out, I’m reminded of how far the industry and market has come.

Some of these materials I’m putting links to are available as ‘publications’ on our website, but some of them have been put out by our clients who have decided to make some of our work public.

This corpus of work followed public sentiments and appreciation of biogas and biomethane as a source of energy across Europe, Australia and New Zealand. Starting with awareness-building and education on this source of green energy that contributes also to circularity, we went on to develop analytical pieces focusing on feedstocks, understanding feedstock value chains, as well as more advocacy pieces that cuts through the challenges in the industry to recommend suitable policy intervention should the government determine this was a worthy cause to pursue.

Blunomy continues to build upon our experience and expertise. During this period, we also performed due diligence on more than 50 projects across different parts of Europe, looked into impact assessment as well as the help clients develop relevant investment cases for this business. Until biomethane becomes a more mainstream form of green energy, the work will not end. Even at that point, there will be new challenges and issues to overcome.

Media and narratives

I used to love The Economist, and I even used to collect various articles to prescribe them to read for my students whilst I was teaching Economics at A Levels. It’s been a great influence on the way I write and approach sharing my opinion on things, and I enjoyed the dry wit and British humour, but these days I find the anti-China slant a bit uncalled for.

Take the recent report on China’s dominance in renewables. One of the article that talked about the improvement of air quality in China has the headline, ‘China’s air-quality improvements have hastened global warming’. I used to laugh at The Economist’s self-deprecating humour and when they lambasted silly but political manoeuvres of US presidents. When they try to criticise illiberal practices in China, I get it and understand the Western liberal lens that drives those considerations. However, this is a blatant low blow, a stark contrast to the highbrow approach that I would usually associate with The Economist.

The article isn’t even so much about China’s air quality but the science behind how some of the aerosols emitted by coal plants could have helped with cooling the atmosphere and how geo-engineering techniques based on that could play a role in climate change. Though latest studies suggest this will probably not be enough to cope with challenges in the shifting agriculture landscape as a result of climate change.

We are entering a new era where narratives are being distorted by English-language media, and it doesn’t help the rest of the world understand China any better.

I recall in 2018, when The Economist started a new column on China called ‘Chaguan’ (which really means Tea House in Chinese), they wanted to understand China better and to help the world do that. That hadn’t quite work.

Place of the Arts

When I watched Secondary the Musical last year by Checkpoint Theatre, there was so much that resonated with me, with the teachers around me about the Singapore education system. It stirred me to feel something about teachers, students, inequality, and even though there was something moving about the end where the teacher chose to stay and continue to live her passion for teaching, I could not but feel a sense of unease for the character.

I had thought and understood that this was what art was to do for us. And this was why there was such a time when the artists seemed as though they were critical of government all the time. Artists’ role in society is ultimately to bring out the subjects, topics and matters worth the attention of society. They could be overlooked groups in society, or matters that still need to be deliberated and discussed, rather than considered a “sacred cow”.

Arts is also a way to cry out in a deeply human way the causes that are worth attention not because of commercial numbers or tangible metrics but that they touches deeper aspect of being human. Whether it is our relationship with nature, or heritage and history, minority culture, there are just things that our marketised, industrialised modernity do not capture though we as humans ought to.

The place of the arts is also for aesthetics and beauty, but one that has identity and soul in the society from which it blossoms. Yet what is the business model for the arts? In a capitalistic society, what are we to do to feed our artists? Whose responsibility is it to ensure they are not exploited by commercial interests to support unworthy causes? What alternative systems are available to fund, to protect them?

Political culture

Woke Salaryman recently posted this comic article in response to comments towards a previous post about workplace ‘politics’. I really like the realism, the clarity and conviction behind their work. I think it is great that they call out the naivety of those who thinks that they can be ‘above’ politics at work but I’m writing this post because I want to add a more nuance layer to the conversation.

I think Singapore, by and large, have always been sensitive to overt kinds of politicking because of the way politics have been portrayed in our history. We take a more superficial view of what politics mean, as though it is all bad and about behaving in deceptive or conniving, self-serving ways.

And in the workplace, we default to thinking that the virtuous approach is simply to bury head and work hard. That can be a great start in a small working team or organisation where visibility isn’t really a problem. It also works well when productivity, key work metrics are not contentious. Then politicking can seem like it’s all about bootlicking, gossiping and acting in the worse, socially destructive ways.

Politics, which is derived from greek words meaning ‘affairs of a city’ is fundamentally relating to governance and interactions between fellow beings living in the same environment, subject to different constraints and influences that are interdependent on one another in the community. The relationship-building, social interactions, tussle for power, influence or mind-share are all part of it. In a workplace, where we are all coming together to achieve something together, it takes effort and the meta-layer of ‘work’ to organise everyone together.

Work today has evolved and become increasingly complex; it is hard to measure individual effort easily, and particularly challenging to identify precisely what the right skillsets are to progress to the next level. It is ultimately the ability to organise others and persuade them to work together that produces value as opposed to working and contributing directly.

There is a role for politics in all of lives, and maybe Singapore needs to build a culture of politcal-awareness and also encourage citizens to appreciate the positive role it can play in society, workplaces. And we may all also learn the right social, emotional intellect needed to handle tricky situations. With the geopolitical climate of the world today, Singapore needs to cultivate more brilliant diplomats than ever before. How else to do so than to help our people recognise the value of such work to the survival and success of a city state nation.

Energy companies of the future

When I started more than 10 years ago in the infrastructure sector focusing on environmental solutions, I saw a lot of new energy startups. A lot of them were facing difficulty on the capital front because all the wealth of the energy sector is tied up in Oil & Gas or the traditional utilities. The startups needed to access regulated infrastructure, regulated markets as well as capital in order to scale but it was difficult. The incumbents were gate-keeping.

So I came to this conclusion that nurturing startups in the energy space wasn’t so much about forming the next unicorn or tech-giant equivalents. It was about strengthening the incumbents; and that these startups are ultimately finding a match in terms of strategic investors in the incumbents in order to exit or to find their innovations adopted through the value chain.

Even for the commercial & industrial, behind-the-meter type solutions, I had in mind that the traditional incumbents would still win out because of their brands and stability.

Turns out that these became areas where they tend to beat a strategic retreat. Because it was too difficult. The big guys had a couple of things they wanted to sell; and they sure could provide some service in order to sell those electrons or molecules. They would even invest in some hardware on your site such as a metering system, or some tanks and nozzles, etc.

But once things got complex, where they have to manage some operations (even virtual ones), and liability at the customers’ sites, it became too difficult. They also think it’s too small, so they left it to whom they believe would be the small guys.

Now it took a long time but these were still difficult projects for the small guys! The EPC players, system integrators, tech solution providers had to come together, get into the complexities of energy service contracting and setting up new operation protocol to get projects up. Slowly they came up; sometimes with investments from the cashflow of these contracting firms, sometimes from family offices and rich borrowers. Financial innovation sort of quickly caught up to support this.

The resulting model, as it turns out, is more of a fund structure where capital is raised in a vehicle that will deploy capital into those energy-as-a-service projects. There is basically an increasing specialisation in the capital-heavy versus labour/technical-heavy segments of the industry. The market is still struggling to understand whether these C&I type energy assets (be it a new chiller/cooler, some kind of tech-enabled energy management systems, or just a set of solar panels with battery energy storage system) is considered infrastructure. Nevertheless, they see it as riskier than traditional state-granted concession type of infrastructure, but still safer than privatw equity where the money is put into operating companies without committed long-term revenues.

Now, I want to address the segment of the market that is also dealing in utility scale renewable power. The end of market moves and financial innovations seem to also point towards a fund structure. Whether it is Equis Energy (now Vena) or even Brookfield Infrastructure that started off in more traditional infrastructure, a whole lot of large scale renewable projects are eventually funded and operated by funds.

I would have imagined that funds would be taking over the more traditional parts of the sectors but instead, what we are really seeing is that funds have become the vehicle for transiting into a new energy system of the world. Is this just an interim solution or do we expect funds to become the energy companies of the future?

Advancement through dilemmas

As I ponder over the paradoxes of our society and nature, I begin to see more and more how our traditional linear paradigms about advancement and growth jars too much against reality.

There are many things that appears contradictory and yet continue to co-exist peacefully in the world without apparent conflict except in our minds. There are tyrants who are charismatic, loved and admired but also incompetent democratically elected leaders who could set a country back by decades. And there are both decentralised and centralised systems that appear to thrive, and also implode.

We ask ourselves if history proceeds through its course regardless of individual’s actions and it is just collective macro force created by the tiny actions of every individual that matters, or that it progresses through the agency of a few, put in the positions of power and influence? It’s not clear at all.

So when we think that progress in the system involves maturity of technology, of having regulation, standardisation, proper rules of engagement in place, we also recognise that these things stifles innovation and block new, emergent contenders from taking over incumbent structures.

Similarly, having contending standards or technology pathways look as though they are going to create a gridlock that prevents the industry from adopting a single unified approach.

The western, perhaps Anglo-Saxon, thought models make it difficult to hold those juxtaposing, contradictory ideas together because it supposes that there is just this one way that is the right way.

What if that is not reality at all?

Blunting policies II

I wrote about the government blunting their policies previously when it comes to SME grants, particularly in Singapore. The same applies to many countries where policy directions are not just unclear but constantly changing. In the energy transition world, so many projects and companies in the US were taking investment decisions on the basis of tax credits for production of renewable energy.

So when the fate of the tax credits was suddenly called into question, it massively derailed the plans of these companies and projects, resulting in a whole sector or industrial sub-segment seizing up. I have always thought it’s incredible that in Europe and US, you could build an entire business or project based on revenues that are only possible because of subsidies or government tax credits. That’s amazing to me because in Asia, companies do not rely on government subsidies to build their business cases. At least not the private companies who have no political influence.

The reason for that is that the private sector is unwilling to take a lot of the regulatory risks from the Asian government, and they are not sure about the longevity of those policies and incentives. They recognise that when leadership changes, these incentives could disappear (as it happened in the US most recently). In other words, those policy measures in Asia are actually pretty blunt because the private sector is not going to respond to it much. US government risk that happening and losing such a precious lever to influence the economy and coordinate the change that is required.

Likewise, in Singapore, one of the biggest advantage that the government have is the ability to coordinate change properly. Technically, they don’t need to use market-based mechanisms to do that, but decades of indoctrination about the need to use free-market capitalism to ensure efficiency have brought us to the approach taken these days. The topic of subsidies is tricky and often at the top level, the thinking is ‘who would not want subsidies and freebies for their business?’ Yet in practice, it is not so easy. But it is not the bureaucracy that companies are unwilling to engage with – it is the uncertainty around the discretion of agencies’ decisions on whether some company or activity merits the funding.

Often, if the government’s grants or subsidies are uncertain and criteria are flexibly applied to accept or reject applications, then companies would rather focus on dealing with the vicissitudes of the market than of the government. I’m writing these because I feel that our agencies could inadvertently undermine something precious that the government have built up in the past. The full implications can only be seen and experience when it’s probably too late.
