@osa_john Do you mean the system for household or an industrial size? How much daily foodwaste are you estimating?
@gazeol-renouvelable_hatem Hatem, let me know if you have some insights
Jack,
Thank you for your question but I doubt many people in this community will have a meaningful response as we are not part of the government structure.
When are you suggesting to do this assessment?
Hi Hatem, thank you for sharing this information – very informative.
Feel free to check out the article by @Ekas at https://biogascommunity.com/2024/09/03/the-growing-landscape-of-bio-cng-in-india/
There are thousands of biogas plants across Europe and I consider it a testament of safety in general. I would suggest checking out the Safety First document by the German Biogas Association to learn about the risks associated with anaerobic digestion and how such risks are mitigated: https://www.biogas.org/edcom/webfvb.nsf/id/en-safety-first-brochure-out-now-in-four-more-languages

Comment by Sara Barle @rea : I think there is a tying of the two presentations within this question. Firstly, there has been a consultation on a future biomethane framework which is investigating what could follow the GGSS. Although this is not confirmed the government has been supportive of biomethane production and its contribution to decarbonising heat. As this is being consulted on its difficult to talk too much about what it will be however Nick rightly confirmed that government are keen to move away from the more generous tariff-based support mechanisms (as with the GGSS and its predecessor the RHI) and is more likely to be a supplier obligation or contract for difference scheme. As the GGSS will end for registered and commissioned application by no later than March 2028 there is a commitment for biomethane into the grid up to a max of 31 March 2043 with as Nick pointed out a contract of no more than 15yrs, So there is time to get a new scheme to follow agreed and embedded to transition. Mick mentioned in his presentation about moving to unsubsidised AD plants and it is hoped that plants will be self sufficient in the future.
Comment by Sara Bartle @rea : Again, I agree it’s a matter for economies of scale and this may be a reason why smaller plants have been less incentivised to participate with the more recent support schemes. Although most will state that the additional costs for connecting to a grid and significantly upgrading from biogas to biomethane are barriers. There is a good argument for encouraging smaller plants where they can manage a more local feedstock and digestate management. They can also produce biogas or transport fuels rather than having to commit to grid connections and/or biomethane upgrading costs. However, these plants may struggle with the initial investment costs unless otherwise supported.
Reply by Dr. Nick Primmer @future-biogas : With the high prices for artificial fertilisers worldwide, demand for digestate is growing. Farmers are also seeking solutions which can help increase soil organic matter (SOM), for both soil health and potential to earn from nature-based carbon sequestration. With specific regard to carbon sequestration, demand for biochar is also increasing.
Reply by Dr. Nick Primmer @future-biogas : The GGSS application and commissioning deadline is now 31 March 2028, and support is secured for 15 years per application.
Reply by Dr. Nick Primmer @future-biogas : Yes, economies of scale can help unlock the potential of AD – we at Future Biogas are targeting 100-150 GWh plants. Nevertheless, small plants may find a niche in remote/off-grid communities.
Kim, thank you very much for replying. As well, I think the Opex of membrane systems is lower? making them more attractive?
Gerard, thank you very much for additional details. I am hoping some of our participants including @Scott.McKay , @bioimpec , @prodeval_david , @azuraassociates_trisha @AzuraAssociates.Deidre can offer their point of view.
Laura, I agree that process optimization should come first and monetization comes after. This is logic. However, taking into account that monetization strategy is very important for no or no-go step of the project as it should be financially viable, I have a feeling in many cases, monetization comes first.
