SuperMarkets - or, you're doing it right

"The propaganda is strong," Youtuber friendlyjordies tells us in a video extolling the power of switching superannuation to fight climate change. "We've all been sold a big lie."

Unfortunately, he is selling a big lie himself - that market mechanisms can do the job of averting climate change. Or, as he put it later in said video: "the platitude that 'you vote with your wallet' is actually true."

It's not.

This post is a follow-up to my 1.5c lifestyle challenge one analysing how much impact switching bank can make - and as I make it clear there, I have personally already switched my super (and bank) to one that invests in renewables (or doesn't invest in coal). I'm not trying to claim that private investment in renewables won't do anything. But, like switching lightbulbs, it's a "solution" that is vastly undermatched to the severity of the crisis we are facing.

Now, in his defense, while he might seem to relish in dunking on climate activists for painting "crap signs" like they are in Year 1 and taking to the streets, friendlyjordies didn't just pull this argument out of nowhere. As I mentioned in the prior post, Australian Ethical markets itself on the promise that their super will help to finance the zero carbon transition. His video is in support of another super fund - Future Super - and it actually draws on a report comissioned by them, alongside climate campaign group 350.org and the UTS Institute for Sustainable Future (ISF).

Sounds great, right? A well-researched plan that doesn't require us to get our lazy arses off the couch? And only 12.4% of Australians have to do it to decarbonise our entire economy - or as few as 7.7% to get us to 100% renewables by 2030? If that's all it'll take, why hasn't it happened already?

Unfortunately, friendlyjordies has fudged the numbers by more than a little. He says less than the 300,000 people who marched in days of action need to switch their super, and they'll make lots of money doing it, when the real number is more like half of all Australians, and returns are definitely not guaranteed. But before we get to that, there are a few big problems with the plan itself.

The biggest warning sign for me was the price tag. According to the report by these research and campaign heavyweights, the cost of transitioning Australia to a zero-carbon grid within ten years is a whopping $788 billion AUD (in 2018). That's several times the amount the federal government recently splashed out to stop our economy going into freefall because of the present pandemic; but more to the point, it's a lot larger than the price given by Beyond Zero Emissions (BZE). Nearly double as much. Their 2010 plan to decarbonise our grid is fully costed, and their initial capital investment is much lower at $370 billion AUD (in 2018 terms, $434 billion AUD). So why the difference?

The reason is, the frame of reference is completely different. The BZE Stationary Energy Plan is, above all, an engineering one; they look at the technical challenge and devise a way to overcome it. The ISF plan, on the other hand, is written from the point of view of an investment firm; they are more preoccupied with the return on investment (ROI), and how technologically sound the solution is doesn't matter as much as if it will generate a 7% ROI.

From the ISF plan

Although they haven't published the technical details the way BZE have, the overall breakdown of energy type in the ISF plan suggests the oversimplification that has led them to arrive at a figure nearly double that of BZE: more than half of power would come from solar photovoltaics (PV).

 
Solar PV and wind power have both been very good investments in recent years, with returns of around 10% on investment. So if that's the metric you're starting with, they seem like a good bet - just keep building them until we have enough, right?

This is the finance world equivalent of everyone in the country just buying 100% renewable energy. As I've talked about in the first post of the 1.5c lifestyle series, our grid doesn't actually work like that - and in fact, we're very close to reaching the limit at which intermittent distributed PV power and wind will start causing problems, unless there are major reforms by the regulators and governments. We are already likely to have days of 75% renewable energy by 2025 - and at that point, the regular will have to switch off power plants to maintain stability. Once that happens, the ROI on those assets will plunge.

The major changes that we need are ones that friendlyjordies and the ISF plan don't talk about - they are ones that market investment can't give us - and they are ones that the BZE plan has modelled and costed. They are grid connections from coast to coast, upgraded transmission lines, large-scale storage, and flattening our evening peaks.

While friendlyjordies does also lampoon the backward-thinking, bucket hat-wearing Dad for asking "what about when the sun doesn't shine?" - the truth is, that's a serious technical challenge. Australians use the most electricity on hot evenings in the summer and shoulder seasons, when they get home and switch on the AC - right as the sun is setting. This isn't an insurmountable challenge; the BZE plan fixes it, by investing in solid upgrades to our transmission infrastructure, linking the two main WA grids to the east coast NEM, and making concentrated solar thermal (CST) with inbuilt molten salt storage the backbone of our grid. That way, when the sun has set on Sydney and Melbourne, our AC units can still be chugging away on daylight in Perth.

The cost of linking the grids like this is significant, and returns on investment are not likely to be 7%. The Australian Energy Regulator recently approved a major interconnector between NSW and SA, which will provide both states with extra stability for distribution in peaks and troughs, as well as reducing the upfront cost of new renewable plants in western NSW. Even this 850km expansion, costing $1.53 billion (in 2020 dollars), is only estimated to return $269 million in likely net benefits - 12.5% overall, but most of these come in indirect consumer savings from dispatchable power and new investment in renewables, not directly from the interconnector's operational income.

The BZE plan puts a price tag of $93 billion AUD on the transmission upgrades required to convert our grid to renewables. This is a cost that will have to be paid, sooner or later - but without a likely ROI from the asset, a responsible super fund manager would never shell out the funds for it.

Then there's the question of energy storage. This is the main answer to Mr. Bucket Hat Dad, and Malcolm Turnbull's Snowy 2.0  is the kind of answer we've been given. There are major problems with that approach - which is why BZE made concentrated solar thermal, with in-built molten salt storage systems, the backbone of their plan. But the up-front costs are higher than solar PV, and despite it being commercially proven overseas, the market will not invest in CST in Australia.

At this point, I can only repeat that the ISF plan hasn't released detailed schematics of their plans. But it would seem that they have arrived at their huge number of $788 billion by picking the most profitable assets, and then massively duplicating them, until enough is built to run the NEM and WA's disconnected grids separately, and there is enough wind and solar power assets to keep on running the grid even when wind doesn't blow or sun doesn't shine.

The kicker is, as they don't seem to have incorporated any kind of storage, that most of these duplicated assets will be sitting idle most of the time. That isn't the case for renewable energy assets today. Bye bye 7% ROI - idle assets that are not selling electricity to the market don't make money.

This plan doesn't hold any water.

Even without all of those details, how has friendlyjordies fudged the numbers? Well, he himself admits 80% of Future Super's money goes into other things than renewable assets, even for their renewable-focused Renewables Plus. The rest sound like good things, don't get me wrong. But in order to reach our 7.7% of super fund assets needed to fund the switch to 100% renewables, then 38.5% of Australians would have to switch to Future Super, or other funds which are putting an equal amount of money into renewables. That's a lot more than the 300,000 who protested over the last summer; it's more than the 4.7 million (33%) who voted Labor in the last election.

So if the 300,000 people protesting in the streets all switched their super (assuming none of them were already ethical investors), we'd get a small portion of the way to 100% renewables. It might tip the stationary energy balance something like 5% towards renewables over the next ten years - not nothing, but a drop in the ocean compared to the task ahead of us.

But surely, friendlyjordies might ask, that 5% is better than achieving nothing, like you and your "crap signs" did in days of climate strikes?

It is true that our government doesn't seem to have budged very far on climate change. But Australians have. In the six months from July 2019 to January 2020, we went from 37% of Australians being "very concerned" about climate change to 47%, and from 43% thinking we are already suffering the impacts to 57%. The number of us "not very concerned" shrank over the same period from 16% to 11%.

Climate protests in that time cannot take sole credit. The summer of bushfires - and the fact that emergency service bureaucrats came out to say they were the product of climate change - no doubt helped shift the conversation. But so did hundreds of thousands of passionate youth. They may not have much in their super balance (and let's be honest, neither do I) - but they know that we cannot leave it up to the markets to solve climate change.

And as someone who attended the climate protests, there's another flaw in friendlyjordies logic; above all, the protests were an expression of anger by a generation of youth, whose future is being trashed - and who don't have much in the way of superannuation balances to switch. In 2017-18, even 25-34 year olds only had an average balance of $33,200 for women and $41,700 for men. Under 25s (the majority of the 300,000) don't even rate a mention. Those aged 45 and up have the decisive amount of the super pool, to invest as they see fit. Definitely not the majority of the protestors.

Voting with your wallet? It means that those with more money get more votes, even though they won't be the ones still around to live with the consequences.

My super is due to mature in 2055. If we haven't ditched our neoliberal obsession with market mechanisms and bloody well built the kind of smart grid that can support 100% renewables within a few years, then the worst-case scenario is collapse of civilization five years before I'm due to claim my lump sum. So I'm not particularly concerned about 7% returns, and I don't want us to fart around with the most profitable solutions when we have the technical know-how to do the job.

Protestors 10 or 15 years my junior, no doubt, care about it even less. They aren't voting with their wallets - they are voting with their feet. And they are doing it right.

We must take action now, regardless of the ROI.

Here comes Hydrogen?

I restarted this blog to start writing some articles about climate change, but also to challenge myself to brush up on things I haven't read about for a while, and to learn things I didn't already know. The past few weeks have been a big exercise in learning things I didn't already know, with the big announcement on June 12 that a new company, H2X, wants to start manufacturing hydrogen-fuelled cars... right down the road in Port Kembla! So, while I've been twiddling my thumbs waiting for a sprained knee to heal, I've been looking into what exactly hydrogen means for the climate.

So... what does hydrogen fuel mean for the climate?

To answer that question, I've had to learn the answers to a few more. How does hydrogen fuel even work? How is it made?

The simple answer is, the same way as most other fuels - but unlike other fuel sources, when pure hydrogen is burnt, it releases only water vapour. Also unlike other fuel sources, pure hydrogen doesn't occur naturally - though it can be found in most fossil fuels, as well as in water. These are the three sources from which pure hydrogen can be derived for industrial use:



The former two sources are emissions-intensive, while the latter only produces the emissions that go into making electricity. Within Australia, these are overall quite substantial, making grid-fuelled electrolysis more emissions-intensive than any other source. However, with 100% renewable energy there are zero emissions generated (other than those that go into manufacturing the systems themselves).


Thus the various "colours" of hydrogen as outlined in Figure 1.1 - labels that describe how it was produced, and that suggest what hydrogen can mean for the planet. "Brown" hydrogen is derived from coal, "blue" from natural gas, "grey" from fossil-fuelled sources. The last sort, the one which excites environmentalists, is "green" hydrogen from renewable electricity-powered electrolysis.

Unfortunately, green hydrogen presently only accounts for 0.3% of hydrogen actually being produced. Around the world, steam reforming (blue hydrogen) makes up the largest portion of all industrial hydrogen production.

It turns out, quite a lot of capitalists in Australia are ready to start making green hydrogen. I first heard of the concept from Beyond Zero Emission's plan to make the Northern Territory a clean energy export superpower - a project which excited Atlassian's Mike Cannon-Brookes. At the time, the thinking was that nations in South-East Asia without our capacity to produce renewable electricity (like Japan and Singapore) would be the destination for green hydrogen from the NT. But, if H2X leads to a boom in domestic consumption, it might be right here in Oz.

After the H2X announcement I started looking into it some more, and it turns out there is a whole wealth of proposed green hydrogen facilities across Australia, including a number in Western Australia, the other main state not connected to the NEM and thus not able to share renewable electricity to the east coast in the traditional way. Thanks to seed funding from ARENA, up to $3 billion AUD of proposals are on the table.

That hasn't stopped our coal-loving Prime Minister from attempting to throw a lifeline to fossil fuel capitalists, by passing legislation to support brown hydrogen production from coal. The promise of carbon capture and storage being integrated into the production is a fig leaf, covering up the fact that there is no need to produce hydrogen in this way when we can do it in others. This is another front in the war on climate action - but it does also show that the coal barons know the writing is on the wall for coal-fired power, and they are looking for a new market to keep their mines from becoming stranded assets.

So, I've gotten a clearer picture on the climate impact of hydrogen... so if the hydrogen is "green", then switching cars from petrol or diesel to hydrogen should be great for the climate... right?

The big announcement for H2X was the "consumer halo", an SUV dubbed the Snowy. With a hydrogen-electric hybrid motor, it will have a range of 650km, and refuel in 3 minutes.

That one has got all of the auto journalists excited and writing headlines dubbing it the "modern Ford" - but "the catch is that the hydrogen refueling infrastructure is no better in Australia than in the United States." Both the ACT and Queensland governments have announced they are installing fuel-cell hybrid infrastructure for their vehicle fleets, with hydrogen-powered Hyundai Nexos already on order. But for ordinary motorists, there is no practical means to refuel, and for this reason, Hyundai is only selling Nexos to government fleets for the time being. It looks like residents of the ACT will get the first chance for private ownership, with public access to the new refuelling infrastructure scheduled in a few month's time.

And that brings me to the elephant in the room - the fact that fully electric cars like the Nissan Leaf, BMW i3 or Tesla are already on the market and have started to reach the point where the charging infrastructure can support most people's needs. Like hydrogen, electricity is as dirty or as green as how it is made, but it requires no major supply lines or new fuel refineries to be set up - they already exist in the form of our grid. So will the Snowy reduce our number of petrol-chugging SUVs, or will it short-circuit the switch to electric vehicles?

There has been some commercial uptake of LPG over the last thirty years, which hydrogen could easily replace, particularly when it comes to buses. But electric vehicles seems to have beaten hydrogen off the mark here as well; Volgren in Victoria has already begun producing electric buses that are hitting the roads, while NSW plans to convert its entire bus fleet to electric.

H2X is no doubt aware of these limits, which is why the consumer halo of the private market isn't all they are looking at. ""Hydrogen fuel cell systems are greatly aligned to the power outputs required for tasks found in industry, mining and marine," Brendan Norman, the CEO and founder of H2X Australia, told CarAdvice."

That's where this announcement is, for me, the most exciting. As of yet, electric vehicles for heavy applications haven't made a big dent in Australia. The headlines have hailed the "consumer halo", but the "industrial floodlight" (if you will) of concepts for tractors, vans and trucks that H2X has released are applications where hydrogen might have the edge over straight electric vehicles anyway; a big hydrogen tank that gets emptier gets lighter, whereas a big empty battery weighs just the same, and requires the same amount of energy to haul around. And it takes a lot of time to recharge, while hydrogen refuels in much the same way (and with much the same speed) as conventional petrol or diesel.

H2X plan to start manufacturing up to 20,000 vehicles within 5 years. That sounds impossibly ambitious - until you hear the qualification that the vehicles will only be "80%" made in Port Kembla, built around imported drivechains. Shipping major components from Europe or the Americas does increase the carbon footprint of manufacturing these vehicles, but if it means they are able to start getting made and reducing emissions from our transport sector (#2 only to energy generation itself) soon enough to make a difference for staying within our 1.5c timeline, it may be an acceptable cost.

So is this the kind of change we need to see?

The South Coast Labour Council teamed up with Labor and Greens politicians to relaunch a Green Jobs plan for the Illawarra in 2019. They are calling for the shrunken industrial district of Port Kembla to be revitalised as a hub of investment in green manufacturing. The 5000 jobs that H2X says it will create are, no doubt, a welcome answer.

The focus of the plan has, naturally, been the single biggest contributor to Australia's greenhouse emissions - energy generation. Right now, despite the growth in renewables in the last two decades, there are only one factory in Australia each manufacturing wind turbines and solar panels. Port Kembla, as a location with steel supply lines and infrastructure already in place, would be an ideal location to build a 100% renewable grid, and avoid the emissions of transport.

H2X plans to make hydrogen cars, and is looking to make a business case for it without government support. But we cannot leave the survival of the climate we depend on to decisions based on what is or isn't profitable. In this era of pandemic and recession, we can and should be demanding nationalised industries which create profit for the public, not a few capitalists.
