IR: Throughout this series, and specifically in episode three, there's been reference made to the hydrogen economy, the elements and technologies that go into it, and its potential as a game-changing energy solution.
However, the investment realities are, for now, a little far off for regular investors.
ZB: When I started looking and investigating or teaching myself a lot more about hydrogen, I was a bit of an evangelist and it was touted as the Swiss army knife for the energy transition.
I've tempered my views quite a bit. It has a place, hydrogen, it's not a near-term solution. It is way in its infancy and potentially one could argue that it serves as a distraction from what we should be doing.
And what we should be doing is ramping up the cheapest form of energy being renewable wind and solar as quickly as possible, coupled with storage. So that's where we think the focus, at least in the next 10, 15 years, in terms of government policy and private investment, needs to be investment into existing renewable technologies.
Campbell is a little more blunt about hydrogen's immediate prospects.
CP: That to me is a very long way from any kind of commercial reality. Despite what you may read today, I think it's still really expensive.
It's not a very efficient storage of electrons. There's a lot of efficiency losses along the way. So for every 100 electrons that a solar farm or a wind turbine produces, only six are then reproduced in the form of hydrogen.
It's difficult to store hydrogen because it leaks through most things, so there's a lot of technical and commercial difficulties around the concept of green hydrogen at the moment, which makes it to us as a post 2030 technology.
It has fantastic utility, perhaps in future, and it makes a lot of sense, but I think globally, there's a lot of perils and pitfalls that we still have to overcome in hydrogen.
In South Africa, there's a lot of talk about Boegoebaai Hydrogen, which is an IDC-Sasol led consortium. Personally, I'm a little cynical about that. I just think that the expense of it.
The coordination required, the technical impediments I mentioned just now, these are all going to get in the way of something like that happening.
As a hydrogen economy rolls out worldwide, I don't see South Africa playing a very meaningful role in it. It's going to be something that's going to be led by nations that have the financial wherewithal to push that technology initially, and they're going to be the ones to have that intellectual property, which they'll benefit from ultimately.
