SAF and fuel mandates

I wrote about the trickiness of cutting subsidies which raises the cost to various groups in the society. This is effectively changing the underlying dynamics of wealth transfer in the society. Another thing that could alter the dynamics is putting some kind of regulation into the system. This tends to be less controversial when people are in agreement that the regulation is necessary. For example, getting companies to increase climate disclosure or just improve packaging labels etc would raise prices for customers as companies need to bear these costs in order to comply.

One could argue the consumers benefit from those regulations so it is fair for them to pay the price. What about when passing environmental regulations? Essentially when you first pass them, it creates benefits for parties going beyond the consumers themselves. Take the case of putting pollution control regulations on a manufacturing plant; eventually the consumers of the product of that plant is paying the cost but the ones who benefit from the regulation are the ones living near the manufacturing plant. That is when you evoke the ‘polluter pays’ principle because in this case, you are regulating away a ‘cost’ that existed in the system rather than creating a new benefit.

That brings us to the issue of climate change and greenhouse gas emissions. I work in the field of energy transition and this is intimate linked to those problems. For one, my day job is focused on solving these issues. What I’m wondering, as the CORSIA regulations kick in to push aviation industry to decarbonise, is whether national governments will choose to spend time going out to set up agreement to enable carbon credit trade which involves corresponding adjustments, or put in fuel blending mandates for Sustainable Aviation Fuel (SAF) which can play a role in airlines meeting CORSIA obligations.

Setting up fuel blending mandates will cost the airlines, who will then pass on the cost to the passengers. And perhaps that will reduce the tourism to the country, or perhaps it could increase the cost of doing business and hence make it less attractive for inbound investments. All of that factor causes it to be unclear who is paying the cost for the environmentalism and whether it ends up hurting the country more. Fuel blending mandate could nevertheless bring about new manufacturing jobs and opportunities that offset the job losses. And at the same time, you might attract relevant, future ready technologies to be based in your country.

Looking at the situation now, it is unlikely for SAF or other green fuels to get into the market through a supply push. The fact is that without a proper, transparent and accepted carbon price, there is no incentive to use a greener fuel that would cost more expensive. And this are green fuel that still ends up emitting carbon dioxide albeit in the short-cycle and hence considered to have zero greenhouse warming potential. Government should take the stance that they will have to mandate the blending and then manage the impact of the costs later. In this case, the ‘polluter pays’ principle could be evoked as a foundation but then various other instruments and tools can be used to cushion the impact for various groups to continue achieving economic objectives.

Cutting subsidies

So having ranted incorrectly about energy subsidies, I saw this article about Malaysia and was reminded of this set of principles I suggested to one of the officials at the Single Buyer of Peninsular Malaysia while working with them on a project. These are ideas on how to move towards a regime where subsidies are reduced and does not apply to everyone:

1. Make them transparent: Start by making clear where there is a subsidy; even when there is a blanket subsidy, make sure that the amount of subsidy is clearly shown to those receiving the subsidy, and that the burden of the subsidy is properly attributed, reported, even publicly. Where price controls are used, the implicit subsidy needs to be made explicit.

2. Share a cross-section of the beneficiaries: Often, fuel subsidies are meant to help manage the cost of living for the lower income. But when it is implemented through price controls or blanket subsidies, it disproportionately benefits the largest energy users. By publicising who are the beneficiaries of the subsidy and how much who gets, you can start considering how to reduce the subsidy for select groups of beneficiary that will be impacted the least.

3. Reduce subsidy for beneficiaries not aligned with policy intents: unless the state policy intention is to benefit the fossil fuel industry, there are always some groups benefiting from a blanket subsidy whose profile doesn’t align with the target group you are trying to help.

4. Keep the subsidy only for groups targeted: once the policy intents are clearer and there is social consensus of who the target groups should be, the subsidies can be pared back to be given only to those who need them. This means that subsidies need to shift from producer-side towards consumer-side. This should be aided by improvements in technology, government data-collection, and new channels for disbursing benefits.

The truth is that economics of renewables have improved and could match fossil energy in some cases. Cutting subsidies for fossil fuel will not just help reduce the reliance on them but free up more government resources to accelerate the transition. We should not allow subsidies to stand in the way of the transition.

What stays the same

Interesting how just when I was thinking about pivot points for change, I chanced upon this Farnam Street article on Bezos and Buffett’s thinking on the impacts of the new on the financial markets. The focus is not so much what will change but what stays the same.

Governments around the world would benefit from the same way of approaching problems – not so much by considering what will change but rather, what is going to stay the same. It is more important to consider what are the new elements that can build upon the existing than to go wild with considering what could throw things off the current course (why, everything and anything, of course!)

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.

Abating the easy stuff

Electrification is often easy in many cases. It is just about changing appliances. Of course, it is also about lifestyle and way of life. I personally still prefer to cook over a gas stove. But I won’t stop cooking without one; I’ve used various electric stoves before as well and didn’t face any major issues.

I’ve lived in house that had gas heating and also one with electrical heating. Regardless, the level of thermal comfort tends to be a trade-off between use of energy and insulation rather than necessarily the equipment for heating though the efficiency of the appliances would play a part. Going on to bigger things, there’s the electrification of transport. For most part, this can be based off just taking public trains or trams instead of driving. It can also involve using electric bikes. Of course finally, there’s the transition to electric cars.

None of these really do reduce emissions in and of themselves assuming no particular changes in energy efficiency of the basic fuel used. It is the energy source that matters. Electrification must be paired with switching power generation to renewable sources such as wind, solar, hydropower and so on. It is meaningless to have electric vehicles on the road and heating of homes with heat pumps when you are generating the power. The challenge of the energy transition is that many things are taking place together and people are not able to really keep track of how much emissions are going to be or might be. Therefore, the direction and rate of change is perhaps more significant to give a sense of how much change can or will happen.

Abatement of emissions through increasing power generation through renewable energy combined with electrification remains the simplest and most effective way to decarbonise our economies. However, the complexity lies in the fact that power prices affects the economy broadly and in many countries, they are subsidised at least for some sectors of the economy. By increasing the demand for power through electrification, the plans for subsidies for certain sectors might be affected. If supply is not increasing fast enough, power prices may increase in a way that reduces the competitiveness of other sectors and the economy as a whole. At the same time, there is also a risk that renewable power supply that is coming online is much more expensive, leading the overall electricity prices to increase anyways even if the supply is keeping up with demand.

Governments are afraid of adversely affecting the power prices as it has very broad sweeping economic consequences. Additionally, power transmission and distribution investments will also have to accelerate to cope with the increased demand and supply for power. Unlike the older set of infrastructure invested over time and much longer ago, we are looking at a huge ramp-up during a short period which means the infrastructure cost will have to be passed on to customers during an intense period of change. So while electrification combined with renewable power generation is the easiest pathway to decarbonise, there are systematic and political challenges around the distribution of the cost of energy transition to consider. Overall, the players who are electrifying some of the previous energy uses actually pass on parts of their cost of transition to the overall system as their participation in the market raises the cost of power for everyone.

For the typical electricity consumer, they would expect their share of the energy transition cost to be converting their load to be drawn from renewable energy sources. However, they now have to pay a share of the heightened infrastructure cost from the increased load, as well as the increased energy cost due to competition for renewable electricity. These complexities are slowing down a process that needs to happen much more quickly.

EV charging incentives

For a long time, EV charging infrastructure has been seen as something in the domain of public goods and should be driven by the government. The challenge on the government side is the question of whether it makes sense for them to invest ahead of EV adoption. Investors are nervous about it because EV chargers seem to them like something, which can pop up pretty much anywhere, and there’s no ‘moat’ to support stable revenues even if they serve as an infrastructure practically. Without proper government-regulated structure, it is difficult for investors to put capital into infrastructure in a place where there’s going to be limited utilisation.

Contrast this with petrol kiosk franchises – they are well-established and have demonstrable cash flow, with strong support from the oil & gas companies backing them. Electricity companies are sometimes backing EV charging point networks in order to increase electricity retail but the truth is that electricity distribution works on an entirely different business model from fuel distribution. A lot of investors believe that the petrol kiosks will themselves be the best location for very fast or ultra-fast chargers (usually 10-20 minutes for a full charge). The other fast chargers (1.5-4 hours for a full charge) will likely be in destinations like shopping malls or other commercial buildings.

Yet EV charging infrastructure is so important as a basis to increase EV uptake which the energy transition desperately needs. Electrification of energy needs from transport enables an easier decarbonisation as we can focus on renewable energy in the power sector while transport and other sectors just have to focus on electrification (which of course, can be quite a pain for some sectors – that’s for another day). So how do we increase and improve EV charging infrastructure? Where can we align the incentives? What role should the government play, if at all? And what if it becomes an extremely profitable business down the line?

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.

GST hike & discounts

As we move from 2023 into 2024, Goods & Services Tax (GST) in Singapore will rise by another 1%. Given the prevailing rate is 8%, the 1% rate increase is actually a 12.5% increase in the consumption tax. No doubt companies will try to convince you to buy stuff before 31 December 2023 to benefit from the lower GST, rather than wait till next year. And if we were to project this logic forward, knowing that GST might eventually be 10%, there is a question of whether we should bring forward some of our purchases even more.

This is more of a psychological trick than anything. Take for example, your interest in an iPhone that may cost you $1000. Buying it before end of the year will save you $10 at the most because of the 1% additional GST that you will need to pay next year. That is hardly a ‘discount’.

Let’s say you got 10% discount from a Black Friday sale instead. Would it compel you to change to a new model rather than stick to your old one? You might. But what if instead of using your existing phone for 1 additional year (eg. 3 years instead of 2 years). If your original phone was also costing $1000, you’d effectively get a discount of 33% just by using it for 1 additional year. Obviously, it goes down if your base time length is longer.

But you get my drift. The biggest discount is when you can use your goods for longer and get more life out of it. There is no point chasing after lower prices of new goods upfront if you keep replacing them quickly. This is an element where sustainability on the consumer end actually lines up with economics but the challenge is psychology.

Structuring incentives for waste

As we try to navigate the climate transition, we are working within a framework of incentives and economic structure where incentives are sometimes mis-aligned to driving climate-positive behaviours. Not just climate but sustainability overall. Waste management represents one of the more problematic area. In many situations, the cost of waste management is pretty much socialised with the cost spread out across a large number of people while the economic benefits accrued by only some. Take electronic waste without proper framework in place for disposal and attribution of responsibility to producers, the society bears the overall cost of managing these difficult waste while the benefits are borne only by the users (especially those who are replacing devices extremely often, and the producers who are selling electronic products.

By incorporating producer responsibility, the cost of disposal and waste management should preferably be priced upfront to customers so that they are paying for the lifecycle cost.

The same should be done for various product packaging. After all, the producers are typically the ones responsible for handling the packaging in the first place so it won’t be too bad for them to take on the responsibility. They can then put the cost into the price tag of the users, who would then be the ones paying for those goods that require the particular packaging. The thing about packaging materials and electronic waste is that they have value as recycled materials anyways – which means that if the ‘disposal’ logistics cost can be at least in part offset through the value recovered from aggregation of these materials, it is a win-win.

What about food waste? Food waste should not be the responsibility of the producers since it is the consumers who determine the level of waste based on how much they purchase and eventually consume. Likewise, those in-between the value chain from farm to table would also be responsible for some of the food waste through their utilisation of the ingredients. The way to make them responsible for the disposal cost is to allow only specific channels of disposing food waste and pricing it properly. The cost of disposing food waste will necessarily be the logistics involved, and then offset against whatever residual value the food waste can generate. What kind of residual value is there? After all, food waste cannot be used to remanufactured food (unlike cardboard whose fibre can be used for recycled paper, or e-waste where the extracted metals can be turned back into materials to produce new products).

Food waste can be turned into energy through anaerobic digestion. And the process will generate methane that can be used as a fuel. The fuel potentially displaces fossil fuel and emits biogenic carbon dioxide in the short carbon cycle. Of course, there are plenty of other biofuels that can also be produced from food waste. If we start putting a value on the food waste, does it mean more of such waste would be produced? It is quite unlikely since the value will probably represent some kind of residual value from the primary use of the food. Yet we find CEO of multi-national company Lufthansa thinking otherwise.

The challenge we have today is that the incentives around recovery of residual value from waste. We will need to redesign how we are able to extract residual value, offset against the disposal costs. We will also need to ensure disposal costs are properly priced and applied to the right parties responsible for the waste generation. We need to set up incentives such that waste is properly sorted and pushed into various streams. The cost of mixed-stream convenience needs to be costed to reflect the cost of sorting.

There’s a lot of work ahead. We need people to get on to them.

Who is the polluter?

There was a recent piece on Eco Business about Singapore’s packaging recycling scheme being delayed and how the polluter-pays principle seems to have failed to take hold in this particular situation. It was partly because of a speech by an activist in the recent SG Climate Rally.

The principle of polluter-pays is important because it helps to internalise the social cost of pollution and allows the market to price it in correctly. The result would be that the production and eventual consumption of the relevant goods stays at the level which is socially optimum.

Product packaging is itself a massive problem where it is clear certain social costs of the waste production is not properly internalised. The fact that supply chains are such that buying a new product is cheaper than the refill version, and the fact that massive amounts of materials are used in packaging without producers having to foot the cost of disposal, seems to be an issue. But the situation is also because waste management is not properly priced. Today, in Singapore, the amount of cost you shoulder for waste disposal is based on where you live and the type of dwelling you live in rather than the amount of waste you generate. This in itself is already not exactly adhering to the polluter-pay principle.

Creating a plastic bottle or aluminum can refund scheme would also jack up the cost of the products but sometimes we forget who are actually the polluters. The ultimate polluters are still the consumers and in making our purchase decisions, if we recognise the cost to the environment and decide that accordingly, it changes the dynamics of the situation and allows the producers to ‘suffer’ the cost from the lack of demand despite the low-ish prices. But that still doesn’t produce a very reliable signal in the marketplace. And that’s why it makes sense to properly ‘tax’ the producers or the consumers somehow to get the market back in line.

As it turns out, the identification of the polluter does not matter much. What matters is that the associated product gets the pollution priced in somehow. You can charge even the shops that are stocking the products. The reason is that the cost will reverberate through the supply chain; the higher price will result in less customers buying it, sending a demand signal that reduces the orders and stocking by the shop, who will order less from their suppliers and so on. Eventually, at the default price point the producer will realise the market isn’t taking as much of the product that they are producing hence reducing their production and hopefully the pollution as well.

The tricky issue is pricing the pollution and getting a sense of how much the marginal reduction in production could reduce the pollution. This is tricky because the average pollution per product isn’t the same as the marginal pollution. And indeed you may have to curb consumption/production very drastically in order to reduce a bit of pollution if there is significant non-linearity involved. I won’t go into the mathematics here but suffice to say, there is reluctance to tinker too much with the pricing of more ‘ordinary’ consumer goods in Singapore. And it might be a shame for sustainability.
