Green Gas Support Scheme Regulations 2021

Lord Grantchester Excerpts

Tuesday 9th November 2021 Grand Committee

[Lord Naseby (Con)]

My Lords, I have come to learn rather than to criticise or analyse in much depth. I was on the Select Committee on energy in the other place and I have tried to keep up to date with developments. I congratulate my noble friend on the fact that, according to his statement, we are the first in the world to go down this track.

My questions are really exploratory. I looked particularly at page 70 of the extensive documentation. First, I have a question about energy crops. It seems that if we are starting in a new area, the bringing together of waste collection is quite a challenge, whereas energy crops by definition are probably on a 12-month cycle. Therefore, the 50% limitation that is mentioned here, while probably the right strategy in the medium term, seems a bit of wishful thinking, certainly in the initial stages. You have to have energy crops to get the thing going.

Secondly, what is the estimated time required to set up any of these plants? Are we talking about a year, 18 months or two years? That is fairly key.

Thirdly, there is the question of the intermix of the gas provided by this route alongside gas from the North Sea. As far as I can see—I have not done an in-depth analysis—there is no reference to this. Is there complete compatibility or does there need to be treatment one way or the other to ensure compatibility in the mix of gases going into the grid?

There is another area that concerns me. Like so many others, I was previously in local government. How will we ensure that local government waste collections collect food waste and other waste suitable to feed these new plants? I do not know the proportions, but at this point in time we in central Bedfordshire are separating only recyclable and non-recyclable waste. I do not know what is happening in the rest of the country, and an update on that would be very helpful.

I thank my noble friend for taking this forward; it is crucially important. I will do my very best to help him on the journey forward.

[Lord Grantchester (Lab)]

I thank the Minister for his explanation of the regulations before the Committee. They are important, because they establish the new green gas support scheme as a replacement for the renewable heat incentive, which closed to new applicants on 31 March this year. This scheme will begin on 1 April 2022, with a reach back to the scheme’s launch date, due to be 30 November this year.

This new scheme is for new deployment and excludes equipment and plants used to register under the RHI scheme, so can the Minister confirm that there will be no crossover of payments between the schemes and that there is therefore little likelihood of much new biomethane coming forward, certainly during the retrospective six months but also for some time to come as new plants come on stream? How soon, and in what number, does the Minister’s department expect applications for new plants to be built and come on stream? It would appear to be quite quickly, as payments will last for only 15 years in a scheme of 19 years until 2041. I presume that the department has confidence in the speed of decision-making, the planning process and the construction phase, all of which will need to go smoothly to encourage speedy deployment.

I must also admit to having some déjà vu moments as I read through the details of the scheme, with recollections of how Conservative Governments regarded such schemes in the past. When I read under paragraph 7.3 of the Explanatory Memorandum that tariff rates

“will be set at a level that aims to encourage continued deployment and ensure value for money”,

and, then, under the very next paragraph, that

“a degression mechanism … will reduce tariffs if certain triggers are met”,

I recall the devastating cutbacks introduced by the Conservative Cameron Government, which slashed support for wind and solar, devastating the industry and undermining investor confidence so tragically. The misprint in paragraph 7.4—

“compromise of an annual tariff review”—

only underlines the impression that undermining support for deployment, especially in conjunction with some sort of levy control framework coming back disguised as a budget cap, will be another feature of this scheme.

It also suggests that few lessons have been learned by the Government. The levy control framework became a politicised mechanism that defied industry understanding and eventually had to be scrapped. Can the Minister give more details today to give confidence that the balance between encouraging deployment and payback to investors will not suddenly lurch towards ill-defined value-for-money analysis being undertaken at the stroke of the department’s pen? Those lost years after those experiences for the solar industry, as well the jobs that were lost, have contributed to the climate emergency that is yet to be recognised fully across government.

Continuing further into the details, I commend the Government on the impact assessment accompanying the regulations. It gave greater insight into the set-up of the scheme and the changes from the RHI regime. This scheme will mandate biomethane producers to produce at least 50% of their biomethane from waste. On page 70 of the impact assessment, the full feedstock energy mix is identified, with 50% of the waste expected to be food waste. Can the Minister confirm whether there is a full definition of food waste that includes food waste in all its various unfortunate and distinguishing forms? My understanding is that this refers not merely to restaurant, domestic household and other post-consumption end-of-the-food-chain waste. It should also include waste that does not even reach the food chain, such as food being rejected or suddenly no longer wanted by supermarkets; this can befall farmers and growers, especially in salad crops and vegetables.

Has the Minister’s department worked closely with colleagues at Defra who are working to reduce food waste through recycling schemes and local authorities? Can he also say what analysis has been undertaken by the department to consider the effects on the renewable fuel obligation undertaken by the Department for Transport, which reuses cooking oils?

I am not aware of the definitions and analysis of “food waste” under the RHI scheme, but I remember that, at one time, miscanthus growing was an important feature of biomethane production plants. In the department’s analysis, maize is the next important feedstock, at 20%, along with agricultural waste. However, I note, under “Non-monetised costs and benefits”, which the Minister mentioned in his opening remarks, the effect on the rural economy. The analysis states that

“two thirds of … plants are located in rural areas, with 80% of all GB plants located in areas with a lower than average GVA.”

I welcome the positive effect that this will have on rural areas. I also note that many properties are not on the gas grid in these rural areas.
