New York — The price tag for driving down global emissions in a big way is, as you can imagine, big. 

BloombergNEF calculates that meeting the goals of the Paris Agreement with a combination of zero-carbon electricity and hydrogen would require more than $60-trillion of power sector investment, plus more than $30-trillion of investment in hydrogen production and transport investment by 2050. Flex a few technical choices — such as switching dedicated nuclear power plants to manufacturing hydrogen — and the total price tag is $100-trillion or more.

A hundred-trillion dollars is a lot of money. Spread it out three decades, though, and it’s merely $2 trillion to $3 trillion a year. It’s also not all the same type of money, so to speak. Those trillions will need to flow to early-stage companies with a hefty appetite for risk but little capital, and from giant asset managers with a low-risk appetite but trillions under management. Pumping up these flows will be a big job for the world’s capital markets. It will also depend on financial plumbing functioning perfectly.

Part of that perfect function is asset rotation, a technical term for companies funding assets at certain stages of their lives, then selling them on to other, better-positioned owners at another stage of life. A project developer uses more expensive capital to fund early work on a wind or solar or battery project; it then sells the asset at a later stage in development, providing the original owner with new investment capital and the new owners with a performing asset.

As my colleague Bo Qin says, “asset rotation shows that markets work”. It’s how millions become billions become trillions.

Private equity — capital that, in the energy infrastructure world, is generally geared towards the earlier stages of asset life — has a record amount of dry powder right now, according to Preqin, a private equity information service. That means more than $2-trillion of funds raised but not yet invested, about eight times more than at the start of the millennium.  

That money pales in comparison to what sits in global retirement accounts: more than $50-trillion at the end of 2019. Almost all of that money is in OECD countries.

Even that pool of money, however, is only about half the total amount of institutional money under management by just the 500 largest asset managers. At the end of 2019, those 500 firms managed more than $100-trillion combined.

It’s safe to say that the world’s largest pools of money have pools of money available to fund deep decarbonisation. But that investment can only take place if money is flowing properly.

What we’re seeing at the moment is that assets just aren’t rotating like they used to, in particular in Europe. An example is EDP, Portugal’s big electric utility, which rotated about 87% of its assets from 2014 to 2016, but intends to rotate only 35% of mostly renewable assets from now until 2025.

There are a number of reasons rotation might slow. The first is that renewable assets with stable financial returns look attractive on the corporate balance sheet. The second is that green finance (such as the more than $700bn of sustainable bonds and debt issued in 2020) allows companies to refinance assets advantageously and increase those returns on their own books without cashing out of early-stage assets.

Certainly there are benefits in utilities owning green-financed assets, but at the same time it throws a wrench into the rest of the market. Early-stage funders (all that private-equity money) may find that high-return expectations make it hard to compete against utilities now buying, refinancing, and holding assets. Pension funds and asset managers may not be able to pry zero-carbon assets away from them.

If the market isn’t working, it could limit the flow of funds to the energy transition. Early-stage investment has higher returns because it is risky; that’s a feature, not a bug. Long-term investors with tens of trillions in assets will necessarily need to fund a huge portion of the energy transition’s capital demand. But they can only do that if they can get their hands on it.
