Why does the same silage give different BMP in different laboratories? A review of the sources of scatter, measures (SD, RSD, z-score), an example and rules for comparing results.
Orden TED/526/2024 of 31 May 2024 established a new methodology for updating operating support (Ro) for plants dependent on fuel prices, with values applied from 1 January 2024.
On 11 June 2024 the New Zealand government dissolved the He Waka Eke Noa partnership and decided that agriculture would stay outside the ETS; pricing of agricultural emissions is to follow before 2030.
According to EPA AgSTAR, 343 commercial farm biogas plants (290 dairy) were operating in January 2023, and 400 as of June 2024; in 2023 emissions fell by 14.8 million t CO₂e.
How South Korea built a food waste collection system: a landfill ban since 2005, weight-based fees with RFID containers and a recycling rate above 95%.
On 17 May 2024 Japan passed the act on promoting low-carbon hydrogen: up to 15 years of price gap support (about 3 trillion yen) and support for hubs.
On 27 May 2024 the EU Council finally adopted the Net-Zero Industry Act (Regulation 2024/1735). The act supports the production of net-zero technologies in the EU, among them biogas and biomethane technologies.
On 28 May 2024 the Irish government adopted the National Biomethane Strategy. It envisages up to 5.7 TWh of biomethane in 2030, about 10% of national gas demand.
Tuas Nexus, Singapore's integrated waste and used water management facility, is to process food waste and sludge in co-digestion. The first stage, planned for 2025, is to be commissioned gradually only from mid-2026.
On 27 May 2024 the EU Council adopted Regulation (EU) 2024/1787. Parliament's position dated from 10 April 2024, and the act will enter into force after publication in the Official Journal of the EU.
Both point and remote methods are used to measure methane emissions from biogas plants: OGI cameras, tracer gas, plume analysers, drones and satellites. We compare their scope, accuracy and detection thresholds.
On 21 May 2024 the EU Council approved Directive 2024/1788 and Regulation 2024/1789. The package sets out, among other things, access of renewable gases to the grid, tariff discounts and connection priorities.
How an energy cooperative differs from an energy cluster, what capacity and area limits apply to biogas and biomethane, and where you need to register.
When a BMP curve has a lag phase and a sigmoidal shape, the modified Gompertz model is used. We explain the parameters P, Rm and λ, and show a calculation and the pitfalls.
On 14 May 2024 the President of Ukraine signed Law No. 3613-IX, which allows customs clearance of biomethane transported by pipeline. It is a step towards exporting Ukrainian biomethane to the EU.
In April 2024 Standards New Zealand published an interim amendment to the NZS 5442 standard, which formally admits biomethane to the grid, relaxes the oxygen limit and tightens the water limit.
On 30 April 2024 the European Commission announced the results of the first European Hydrogen Bank auction: almost €720 million for seven renewable hydrogen projects in four countries.
On 23 April 2024 the Hiringa Energy station in Wiri (Auckland) was officially opened, part of a green hydrogen refuelling network for trucks that the company describes as the first in Australasia.
On 24 April 2024 the European Parliament adopted at first reading its position on the regulation on packaging and packaging waste. The requirements concern, among other things, compostable packaging, reuse and recycling.
With Resolution 132/2024/R/eel of 9 April 2024, the Italian regulator ARERA implemented a mechanism of minimum guaranteed prices (PMG) for biogas plants whose support expires by the end of 2027.
A municipality must provide separate collection of six streams, including biowaste, and residents must comply. We explain the fractions, bin colours, the exemption for home composters and the EU deadlines.
A biogas plant with a CHP engine can be converted into a biomethane plant by adding upgrading and a grid connection. We indicate what needs to be calculated: biogas, heat for digestion, support, permits and the schedule.
The report "Biogases towards 2040 and beyond" estimates the biomethane potential of the EU and of the United Kingdom, Norway and Switzerland at 111 billion m³ per year in 2040, including 74 billion m³ from anaerobic digestion.
How can a BMP curve be described with a single equation? The first-order model gives B₀, the rate constant k and the t90 time. We show the fitting, an example and the limitations of the model.
