Wet fermentation operates at a dry matter content below about 15%, dry fermentation at about 20–40%. A comparison of technologies, substrates, energy consumption and typical problems.
We explain the architecture of Canada's Clean Fuel Regulations: who is obligated, how credits are created, how the CATS registry and the price mechanism work, and what follows for biogas projects.
The Latvian mandatory purchase system was financed by the OIK component added to bills; it bought electricity from cogeneration and biogas, paid for through charges on bills. No new rights have been granted since 2012, and in December 2022 the government decided to cover the costs from the state budget.
H2 2022: day-ahead market (RDN) PLN 903.4/MWh against FIT PLN 745.8/MWh. The price peak, the levy to the Fund that did not affect biogas, and what to do with a positive balance.
On 4 January 2023 the Indian government approved the National Green Hydrogen Mission: production capacity of at least 5 million t per year by 2030, about 125 GW of renewables and an initial budget of 19,744 crore rupees.
The Minister of Climate's regulation of 28 December 2022, published on 9 January 2023, sets requirements for mechanical-biological treatment of mixed municipal waste: fractions, stabilisation, fermentation and alternative fuel.
On 5 January 2023 the CSRD directive on sustainability reporting entered into force. About 50 thousand companies in the EU (compared with about 11.7 thousand covered so far by the NFRD) will report environmental and climate impact under uniform ESRS standards.
On 28 December 2022 BP completed the acquisition of Archaea Energy, an American developer of landfill gas RNG projects; the value of the transaction is USD 4.1 billion.
Uncontrolled decomposition of organic waste emits methane, nitrous oxide and ammonia. A biogas plant can reduce these emissions, but only if it is itself tight and well run.
At the start of 2023 an amendment to the Act on Biocomponents and Liquid Biofuels entered into force: minimum NCW fulfilment of 80%, a reduction factor of 0.82 and limits for biohydrocarbons and Annex 1 feedstocks.
In December 2022 construction began on Phase III of the Laogang bioenergy project (Pudong): 2000 t of wet waste a day, 1.65 billion yuan of investment and commissioning planned for May 2025.
Methane escapes from biogas plants through safety valves, membranes, open digestate tanks, CHP engines and off-gas. We discuss the sources, ranges of losses from measurement campaigns and ways of reducing them.
Depackaging separates expired food from packaging before digestion. We explain waste codes, the permit, the BDO, UPPZ and the effect of contaminants on digestate quality.
Differences between micro, small and large installations: choice of digesters, CHP, automation, staff and unit cost. What is gained from scale and what is lost.
The Act of 15 December 2022 limits gas prices for eligible customers in 2023 to PLN 200.17/MWh. A VAT refund on bills is provided for low-income households. It enters into force on 21 December 2022.
On 19 December 2022 EU energy ministers agreed a general approach on the regulation on reducing methane emissions in the energy sector: measurement, leak detection and limits on gas flaring.
In December 2022 the government of Costa Rica presented the National Green Hydrogen Strategy 2022–2050; it assumes 200–750 MW of electrolysis by 2030 and a hydrogen cost of about USD 2/kg.
On 18 December 2022 the EP and the EU Council agreed the ETS reform: a 62% emission reduction by 2030, a new system for buildings and transport from 2027 and monitoring of emissions from municipal waste incinerators from 2024.
On 13 December 2022 Parliament and the EU Council reached a provisional agreement on the CBAM mechanism. The transitional period is to start on 1 October 2023, and the full system from 2026. Fertilisers are in scope.
On 7 December 2022 the European Biogas Association published its statistical report: biomethane production grew by 20% in 2021 to 3.5 billion m³, and biogas and biomethane together supply 18.4 billion m³ of renewable gas.
In Ontario's FIT programme, farm biogas received up to 26.3 cents per kWh in 2016, and up to 25.8 cents in the final, fifth round in 2017. We compare the price schedules and describe the end of the programme.
On 30 November 2022 the European Commission proposed a regulation on packaging and packaging waste (PPWR): reduction targets, recycling requirements, deposit return systems and rules for compostable packaging.
On 28 November 2022 Shell announced the purchase of the Danish Nature Energy for about USD 2 billion (EUR 1.9 billion). It is one of the largest such transactions in Europe and a significant signal for the biomethane market.
The circular economy combines the waste hierarchy, recycling targets and closing the nutrient loop. We explain the EU and national frameworks and the place of the biogas plant between energy and fertilisers.
