How to enter an agricultural biogas plant in the KOWR register: who must register, what the application contains, what conditions must be met and what reports to submit after registration.
Slurry and solid manure emit methane during storage and N₂O and ammonia during storage and application. We explain the mechanisms, the influencing factors and mitigation measures, including digestion.
Canada's 2023 Budget introduced a refundable investment tax credit for clean hydrogen in the range of 15–40% depending on carbon intensity; alongside it operates a clean technology credit of up to 30%.
In March 2023 the New Zealand government announced a waste strategy and collection standardisation: recycling in cities by 2027 and food waste collection by 2030, with a reduction in landfill methane.
On 30 March 2023 the Australian parliament passed the Safeguard Mechanism reform: emissions limits for the largest facilities are to fall by default by 4.9% a year to 2029–30, and the new system is to operate from 1 July 2023.
On 30 March 2023 the European Parliament and the Council of the EU reached an agreement on the revision of the Renewable Energy Directive: a binding target of 42.5% in 2030 with the possibility of 45%, new targets for transport and industry, and rules for biomethane.
Slurry gives a low methane yield per tonne, but it performs important functions: buffer, water, microorganisms, trace elements and lower emissions from storage. What is known about its role and limitations.
On 28 March 2023 the Council of the EU agreed a general approach to the decarbonised gas and hydrogen markets package. Parliament adopted its position on 15 March. The changes concern, among other things, connection and tariffs for renewable gases.
On 28 March 2023 the Council of the EU formally adopted the regulation introducing a 100% reduction in CO₂ emissions from new cars from 2035. A dispute over the role of synthetic fuels came first.
A paper from the University of Waikato in “Energies” (2023) combines a literature review, surveys, chemical analyses and BMP tests to assess biogas from dairy farm manure.
On 23 March 2023 the European Parliament and the Council of the EU reached a provisional agreement on FuelEU Maritime: a reduction in the emission intensity of shipping fuels of 2% in 2025 and up to 80% in 2050.
On 16 March 2023 the Commission proposed the Net-Zero Industry Act (NZIA). The technologies covered by the target of 40% EU production by 2030 include biogas and biomethane technologies.
On 16 March 2023 the Commission presented the concept of the European Hydrogen Bank: support mechanisms for the production and import of renewable hydrogen, with a pilot auction planned for autumn 2023.
In fiscal year 2004 Japanese wastewater treatment plants produced about 290 million m³ of biogas, of which only 20% was used to generate electricity. A review of data and of the B-DASH demonstration programme (since 2011).
A guarantee of origin (GO) confirms that 1 MWh of gas comes from renewable sources and can be transferred independently of the physical gas. We explain the RED II rules, registers, validity and the risk of double counting.
Restaurants and canteens must collect kitchen waste separately and pass it to an authorised collector. We describe the codes, the contract, the BDO, UPPZ requirements and the route to a biogas plant.
On 13 February 2023 Global Hydrogen signed a contract to build a complete 1 MW biogas plant in Markowice (Strzelno municipality) on a design-and-build basis, worth PLN 15.5 million, using SMBP technology.
Co-digestion combines substrates with different properties. We show how to build a mix: dry matter balance, C/N, buffer, inhibition risk, logistics and the gradual introduction of changes.
On 21 February 2023 the IEA published the Global Methane Tracker 2023: methane emissions from the energy sector in 2022 were about 135 million tonnes, i.e. about 40% of human-caused emissions. Most reductions are technically possible.
From 15 February 2023 the EU gas market correction mechanism applies, a temporary price cap on the TTF triggered once EUR 180/MWh is exceeded. It is meant to limit price spikes, not to set a fixed price.
On 10 February 2023 the Commission adopted two delegated acts: the definition of renewable fuels of non-biological origin (RFNBO) and the methodology for assessing emission reductions. Hydrogen from biomass is subject to separate RED rules.
In the 2023–24 budget the finance minister announced 500 new "waste to wealth" plants: 200 CBG plants (including 75 municipal) and 300 cluster plants. Outlay: 10,000 crore rupees.
Steam reforming turns CH₄ from biogas or biomethane into H₂ and CO₂. We explain the reactions, conditions, efficiency, the mass and emissions balance and the place of the process among biohydrogen production routes.
How to design the use of landfill gas in gas engines: from wells and cleaning, through capacity selection, to renewable energy support and the risk of declining yield after the landfill closes.
