Municipal wastewater, process wastewater and rainwater are potential sources of water. We discuss recovery technologies, examples from Singapore, Namibia and Israel, the "Moja Woda" programme and the role of digestate.
The full path of a batch test: sample preparation, inoculum, filling, incubation, gas measurement, termination and calculations. With a checklist and typical mistakes.
The act of 17 August 2023 introduces into Polish law a definition of biomethane, a register of biogas producers at the Energy Regulatory Office (URE), guarantees of origin and a support system for biomethane from installations of up to 1 MW (20 years).
A biogas plant may require an integrated permit, an emissions permit, a waste processing authorisation or only a notification. We explain what applies when and according to which thresholds.
The act of 28 July 2023 amending the Energy Law, published on 23 August 2023, contains rules on connecting biogas plants with biogas storage, aggregation and the reserve supply of gaseous fuels. It enters into force on 7 September 2023.
Biomass gasification yields syngas, from which hydrogen can be separated or bio-SNG produced. We describe reactors, gas cleaning, yields, the GoBiGas example and technology maturity.
We explain why in the US renewable natural gas goes mainly into transport: how D3 RINs from the RFS, LCFS credits and other support instruments combine, and what the risks of this model are.
On 31 July 2023 the New Zealand EPA approved (announcement of 10 August) the import and manufacture of 3-NOP, the active substance in Bovaer, which according to the manufacturer cuts methane in cows by about 30%; approval under the ACVM regime is still needed for use on farms.
The agricultural biogas plants act, published on 11 August 2023, introduces into the fertilisers act rules on digestate products: notification to WIORiN, documents, contaminant limits and penalties of up to PLN 100 thousand.
BMP is the maximum amount of methane that can be obtained from a unit of a substrate's organic matter in an anaerobic batch test. We explain what it is used for and what it does not tell you.
On 25 July 2023 the Council of the EU approved the FuelEU Maritime regulation, adopted by Parliament on 11 July. Shipowners will account for the emission intensity of fuels, and a deficit carries penalties.
Manure and slurry are category 2 UPPZ, and kitchen waste is category 3. We explain the exceptions from treatment, the effects of mixing, distances from animals and documents for transport.
The distribution grid has limited absorption capacity, especially in summer, so biomethane is sometimes injected into a higher-pressure grid or via reverse compression. We explain pressure levels, the choice of injection point and the criteria.
JBS reported in July 2023 that biogas from a covered lagoon at the Rivalea plant in Corowa meets 85% of the peak power demand of the farm and abattoir; the company announced investments of more than 20 million AUD.
A review in the journal Energies (July 2023) analyses biogas upgrading methods in South Africa and estimates the potential at 3 million Nm³ of biogas a day. In 2022 the industry put biogas capacity at about 30 MW.
In July 2023 Panama's cabinet approved the National Green Hydrogen and Derivatives Strategy (ENHIVE): a target of 500 thousand t of hydrogen and derivatives by 2030 and 5% bunkering of ships with hydrogen-based fuels.
The act of 13 July 2023 introduces a deposit return system in Poland for plastic bottles, cans and returnable glass bottles: a deposit of up to PLN 2, collection levels from 77% in 2025 to 90% in 2029.
On 13 July 2023 the Sejm accepted the Senate's amendments to the act on facilitations for agricultural biogas plants. The act sets capacity limits (3.5 MW electrical), shortens land development decisions to 65 days and introduces a siting resolution.
On 27 June 2023 the Swedish government announced support equivalent to gödselgasstöd also for Q4 2023. The pilot scheme from 2014 pays up to 40 öre per kWh of biogas from slurry.
H1 2023: the day-ahead market fell to PLN 567.2/MWh, the FIT is PLN 745.8/MWh. Does flexibility make up the difference, and what about the balance after the crisis?
On 21 June 2023 the EPA announced the final Renewable Fuel Standard volumes for 2023–2025, assuming 25% annual growth of RNG in the cellulosic category and without eRIN provisions.
The Bulgarian regulator's decision of 30 June 2023 sets feed-in tariffs for a year from 1 July. Energy from biomass was added to the list, and premiums were differentiated for installations up to 500 kW and above.
Sinopec announced in early July 2023 the start of production in Kuqa in Xinjiang: about 260 MW of electrolysers and a target of about 20,000 t of hydrogen a year.
On 5 July 2023 the European Commission proposed binding food waste reduction targets for 2030 and extended producer responsibility in the textiles sector. The change will affect the food waste stream.
