"Further downward movements in near-term market"
Mike Ridler - CEO at C-Zero

“Uncertified waste now generating interest – but an abundance of volumes has prevented much price movement”

Monthly Report | July 2025
RGGO
- The traditional summer slowdown was delayed by a few weeks this year as demand for certified waste/resi seemed to dominate, with prices for 2024-25 volumes settling in the £13-15/MWh range.
- Demand for 2024 crop has slowed as buyers turn to 2025 volumes, but even prices there have been gradually eroded to the high £6s / low £7s.
- There has been a dribble of enquiries for uncertified waste/resi. It has been encouraging to see some demand but given the overhang in supply of the older certificates this has not been enough to have a noticeable impact on prices.
- We attended the ABDA Biogas show in Birmingham and whilst the harvest season kept many Farmer/AD Owners away, it was otherwise very well attended. It seemed that general positivity and confidence in the development of the Biogas market has returned. There is lots of talk about building sites under the new GGSS but it will remain to be seen how many become operational.
- In April, ADBA called on the UK government to unlock £1 billion of AD investment. They highlighted a potential increase in output from 13 TWh currently to 30 TWh by 2030 if the right policies are put in place.
- Many AD owners/operators we spoke to that are over halfway through their RHI period are beginning to look to towards the end of the subsidy period. Without firm support hundreds of small biogas plants face closure by 2031 due to expired subsidy schemes.
“Scepticism on speed of UK and EU ETS link reversed May UK market gains”

“Some upward movement – and AIB report shows healthy market growth over the longer term”

CCO – Chief Commercial Officer
EuGo
- Low liquidity towards the end of H1 initially kept a lid on prices.
- The number of trades picked up at the start of H2 which helped support some upward movement, but most of these trades indicated a general acceptance of the current market rather than any fundamental shifts.
- Reservoirs in Norway and Sweden look like they may drop below 2024 levels. Nordic-Hydro continues to be a key market influence, so this is suggestive of a potential alleviation of GO oversupply and has lifted some of the downward pressure on prices.
- The AIB released their annual report which showed that 2024 was a record-breaking year for their GO system. GO volumes surpassed 1,000 TWh across participating countries and both transfers and cancellations were higher than ever before. This is a positive sign for the continued health of the GO market over the longer term.
