In our ESG and Climate report yesterday we highlighted inflation as one of the most significant risks for 2022 and the estimates in the exhibits below do not leave us any less concerned. The US has struggled to meet solar installation plans for 2021, falling short of early-year estimates because of limited equipment availability and higher equipment prices. While some of this has been the result of the supply chain challenges of 2021, some shortages have also been the result of very strong global demand. The idea that we can increase solar installations in 2022 without creating more supply issues (and more inflation) should be questioned, especially in light of planned additions in China, which will consume an increasing share of Chinese solar modules.
It should not be surprising that 2021 has seen a rebound in emissions as nothing has changed fast enough over the last 24 months in terms of renewable power additions and carbon abatement to offset more than the underlying growth in power demand, and based on what we are seeing in European and Asia LNG markets, we have fallen short of demand growth. The wind capacity chart below has one main conclusion – not enough. One of our main inflationary fears for 2022 is that both wind and solar installation rates need to step up meaningfully from current levels to make a difference – the IEA suggests that installation rates need to double (at a minimum). It has already proven difficult to meet installation targets in 2021, in part because of supply chain issues but also in part because of material shortages, all of which have led to rising installation costs, against the longer-term run of falling costs because of learning curve gains. We believe that costs will rise again in 2022 and 2023 as installers/projects compete for limited solar module and wind turbine components
While we would generally avoid quoting work from a company that we might consider a peripheral competitor, we are happy to do so when it backs up one of our central themes – in this case, inflation in renewable power costs. The quote is taken from the Wood Mackenzie report flagged article linked here and discusses a view on how challenges that renewable power installers have faced in 2021 will extend into 2022. The quote talks about shortages of renewable power equipment, and the obvious consequence will be higher prices for that equipment, especially as raw material prices for components remain high and possibly move higher. In our ESG and Climate report today, we talk about the need for some commonsense oversight such that impractical ESG investing targets do not limit the ability of producers of critical fuels and materials to operate.
We focus today on raw material inflation and use the IEA analysis of materials demand (excluding steel and aluminum) in EVs and renewable power, creating a price index for the materials in question. This index is a straight average, but we will develop indices for specific sub-industries and include these in our next ESG and climate report. What is important is that the index below is up over 50% since the beginning of 2019 and this is before many of the EV plans and power plans move from planning to construction. We have highlighted inflation risk for more than a year now and remain very concerned that when many of the new auto plants start and many of the incremental renewable power facilities move from planning to equipment purchasing, we will see bottlenecks and faster price increases. See more in today's daily report.
The charts below both support our view that we will see continued inflation in renewable energy costs, rather than the deflation that is baked into all of the forward models. It is easy to forget that some of the early solar installations are coming to the end of their useful lives and are retiring – these are gaps that new solar will need to fill. Wind power has the same issue, as many of the original wind farms need equipment replaced and the introduction of recyclable wind turbine blades has been in recent manufacturers' announcements. When we see analysis of who is going to use which tranche of new renewable power for which new hydrogen project we see major gaps in the power demand analysis, in part related to power demand growth at the domestic consumer – because the more rapid introduction of EVs – and in part because or retirement of facilities and the need to replace them.
In our ESG and climate piece yesterday we discussed rising costs of climate-related actions, with a focus on some of the likely inflation in renewable power costs. The optimists are looking at the Exhibit below, and what were falling module costs through 2020, and concluding that solar installations can grow and that costs can still fall. While the module shipment growth in 2020 was impressive at 33%, some of the forecasts of what will be needed call for a much more dramatic rate of module growth than we saw in 2020.
The exhibit below highlights one of the more significant constraints for green hydrogen, which is that the abundant low-cost power opportunities (strong wind and lots of sunshine) are often not where demand for hydrogen exists and the challenge is how to transport it. The problem with reacting it to make something else and then recovering it at the point of use or a distribution hub is that hydrogen is very light and you end up moving a lot of something else to get a little hydrogen. Air Products is looking at making ammonia in Saudi Arabia and shipping the liquid ammonia and the project below is looking at using toluene as a carrier in what appears to be a closed-loop with toluene moving one way and methylcyclohexane moving the other way. The liquid shipping would be cheap, but with the MCH route, only 5% of what you would be moving to Japan would be the green hydrogen. Using ammonia the green hydrogen content is slightly less than 18%, but you have to make the nitrogen on-site. The cost of making the nitrogen would be a function of the local cost of power and these remote locations should have very low-cost renewable power. In the example below, the opportunity is likely unique to the refinery structure and shipping opportunity and we doubt that it is easily replicated in a way that would be more economic than shipping ammonia or shipping compressed hydrogen itself.

There are several headlines today that speak to one of the most pressing issues that we have with the pace of energy transition – the competition for renewable power and the likely inability of the industry to keep up with the competing needs, let alone do so without significant power cost inflation.
The exhibit below summarizes well one of the primary concerns that we have with some of the very ambitious goals for decarbonizing power grids, EV introduction, the further electrification of industry, and hydrogen. While the solar module price increase does not look that significant (yet), to put it in context, solar module prices have collapsed from over $1.80 per watt in 2010 to below $0.20 in 2020, and many of the expectations around cheap hydrogen require the cost to keep falling. The bigger concern is the polysilicon price, which is up 160% this year, good for the polysilicon producers like Wacker (see the headline here), but bad for the solar module producers, who are seeing major margin squeezes, especially given the rise in copper and silver as well this year. The raw material pressure should drive further increases in solar module pricing and while the higher margins for polysilicon will likely drive expansion investment, the metals are harder to call, given the ESG views on mining. We remain firmly of the view that raw material availability and price inflation, as well as module and wind turbine manufacturing capacity, will be the rate-determining constraint in terms of the growth in renewable power and this is why we question all of the near-term cheap power and cheap hydrogen goals that are being suggested by potential producers and government agencies.
