My Lords, I very much support what the noble Lord, Lord Alton, and the noble Baroness, Lady Finlay of Llandaff, said about tidal power. I have followed what has happened on the Severn, and it is terrific to see that it is now coming back into play. Tides are probably our most reliable power source in the UK. There will always be a tide, when there might not be some wind.
I support pretty much all the amendments in this group which look at diversifying the sources of energy—all of what the noble Earl, Lord Russell, and the noble Baroness, Lady Grender, said. I shall speak specifically to Amendments 30 and 33, which would exclude biomass from the definition of clean energy, and there are many reasons for this. Over the past few years, it has become completely clear to me and, I think, to many other noble Lords—including the noble Lord, Lord Forsyth, who is not in his place, and who spoke about this issue during a Question of mine a couple of weeks ago—that while biomass is okay on paper, in theory, and on a very small scale in practice, it is not at all okay on the big scale at which we practise it. We cannot go on using it to reach net zero. I do not know whether noble Lords saw the “Dispatches” and “Panorama” programmes; also, an Ofgem investigation has found that biomass energy generators in the UK have “misreported”—that is not my word—the data on where they get their wood from. In other words, it is not waste wood. The idea was that offcuts and waste wood were used and burnt. That in itself was a fallacy, because the burning of wood releases so much carbon, but the story gets worse.
As the Wildlife and Countryside Link put it:
“Bioenergy which burns woody biomass actively harms nature restoration efforts and will not contribute to GB Energy’s goals of clean energy, energy independence, nor cheaper energy bills.”
This is before you get to the negative health impacts of sourcing and burning biomass, the damage it is doing to the renewable energy brand, or, importantly, habitat destruction, which so often gets missed in the race towards net zero.
I want to raise a couple of wider bioenergy issues. I am really worried by the idea of BECCS—bioenergy with carbon capture and storage, which the Government seem intent on believing is an inherently negative emission technology. Let us look a little further. The assumption is based on the idea that all biomass inputs are waste—which not even our sustainability requirements require—or are balanced out by regrowth. If it was entirely the former, let us be clear that burning waste wood releases more emissions than natural degradation, through which carbon is absorbed by the soil—and that is before you get to all the other environmental benefits of leaving forestry residue in the forest where it belongs. If we assume the latter to be true, it is only the case after several decades and, again, only if the trees are actually replanted. In short, there is no way to verify that biomass is carbon neutral at any point.
I feel that this has gone so far that it would even be worth the department itself sending someone out to where these pellets are apparently sourced from—in North America and in the province of British Columbia. Perhaps there is something that DESNZ or its predecessor, BEIS, has already done, which I have heard rumours about. I would be very grateful if the Minister could tell me if this has happened or is planned.
Biomass is not carbon negative. I understand that the Minister’s department baked BECCS into our carbon budgets over a decade ago and that they are ongoing in future carbon budgets, but the logic is flawed and, at its worst, truly deceitful. Just because we classify something as renewable or carbon negative does not mean that it is. We do not have time to grow the trees to absorb the carbon we are pushing into the atmosphere. As the noble Lord, Lord Forsyth, said, we are cutting trees down in North America and Canada, turning them into wood pellets, shipping them by various means back across Canada and the Atlantic, often to a power plant in Yorkshire where they are belting out carbon into the atmosphere, and we are calling this clean and renewable. My Lords, it is not.
My question for the Minister—apart from whether he is on this mission to find out the extent of this—is whether he will rule GBE out of involving itself with biomass power generation, and will he come back to me on what investigations his department has done in the past few years? Can we be honest at this point and remove the absurd assumption that biomass is inherently carbon-neutral at the point of use?
