‘Green is actually totally renewable. When it comes to natural gas, although they call it clean, it’s clean as opposed to coal and diesel, petrol and so on, because your carbon emissions are higher,’ says Andries van der Linde, renewable energy head at Siyakhula Sonke Empowerment Corporation.
JEREMY MAGGS: Many large energy users do not see natural gas necessarily as a viable option for the production of hydrogen. This is a view that’s been put forward by diversified minerals and investment group, Siyakhula Sonke Empowerment Corporation [SSC]. Renewable energy head, Andries van der Linde, is with us now as the hydrogen debate gathers some steam, and that pun is intended.
ANDRIES VAN DER LINDE: Ja, okay, let’s look at green first. Green is actually totally renewable, totally green, where you actually produce, if you look at hydrogen, you produce it from a renewable energy source because hydrogen is produced using an electrolysis plant, which splits your water into hydrogen and oxygen, and that uses electricity. That electricity must come from a green energy source.
JEREMY MAGGS: So how do you see green hydrogen then ultimately helping in ensuring stability for the big mining companies?ANDRIES VAN DER LINDE: Well, one of the big advantages of hydrogen, and I feel very strongly about it, is that hydrogen is something that any country can produce.
Whereas say for instance, if you go to Europe, you’ve got wind farms all over the show so that the wind farms there are connected to your grid. So if you say, well, I want to produce hydrogen from the grid, but I want to only use, say, renewable energy from the wind turbines, you’ll still, even if they administratively can prove that you actually, although it’s very difficult, only use the wind energy component, you still pay grid prices.
