Directive 2018/2001 requires renewable energy support to be market-based rather than fixed tariffs. It also prohibits retroactive changes and allows national support schemes to be opened to generators from other countries.
The injection station is the last element of a biomethane plant: it measures the quality and quantity of the gas, regulates pressure, odorises and cuts off non-compliant gas. We describe the components and the order of the equipment.
Vinasse is a liquid waste from distilling ethanol from cane, traditionally used as a fertiliser. We explain what anaerobic digestion changes, what role filter cake plays and what the limitations are.
On 12 February 2021, the regulation establishing the RRF recovery fund, worth EUR 672.5 billion, was signed. At least 37% of the funds of national plans are to support climate goals.
Researchers from Jiangxi Agricultural University increased the methane yield from the co-digestion of rice straw and pig slurry by about 45% through biological pretreatment with a cellulolytic microflora.
Animal by-products fall into three risk categories. We explain what belongs to categories 1, 2 and 3 and what may be done with them in a biogas or composting plant.
Presidential Decision No. 3453 of 30 January 2021 converted Turkish YEKDEM support into lira: 0.54 TL/kWh for biogas and 0.32 TL/kWh for landfill gas, with a cap in US cents.
The Act on the promotion of the hydrogen economy and hydrogen safety entered into force on 5 February 2021 and established a committee chaired by the prime minister.
On 2 February 2021, the Council of Ministers adopted PEP2040: three pillars, a target of at least 23% RES in 2030, a falling share of coal in electricity generation, and the development of offshore wind, photovoltaics and nuclear power.
Orlen Południe has taken over an unfinished biogas plant in the Ryn municipality and intends to complete it as a biomethane plant producing about 7 million m³ per year. Completion was planned for the end of 2022.
On 20 January 2021 decree DS 8/2019 was published, setting collection and recovery targets for end-of-life tyres under Chile's REP law on extended producer responsibility.
The European Biogas Association published on 25 January 2021 a report for 2019: 167 TWh of biogas and 26 TWh of biomethane, with data from 19 countries.
Foam in the digester can block gas pipelines and damage the roof. We set out the causes, immediate measures, antifoams and prevention.
Will a biogas plant on the RDN earn as much as on FIT? In H2 2020: no — PLN 236.6/MWh against PLN 617.5/MWh. The series method and support law.
On 14 January 2021, the Ministry of Climate and Environment published the draft hydrogen strategy. It assumes 2 GW of electrolyser capacity by 2030 and six strategic goals.
The Polish Power Exchange (TGE) and the Polish Oil and Gas Company (PGNiG) signed a cooperation agreement on building a biomethane market. The first stage is to use the register of certificates of origin and the system of guarantees of origin.
GWP converts methane into CO₂e, but the result depends on the time horizon. We explain the difference between GWP₂₀ and GWP₁₀₀, the IPCC values and how the choice affects the assessment of a biogas plant.
Palm oil mills produce POME effluent with a high organic matter content. Since 2014 new and expanded mills in Malaysia have had to have biogas capture or methane avoidance systems.
Since 1 January 2016 selected wastes with codes 19 08 05, 19 08 12, 19 08 14, 19 12 12 and from group 20 may go to landfill only if their calorific value is below 6 MJ/kg TS. We explain the scope and the consequences.
The German fuel emissions trading system (BEHG) started with a fixed price of EUR 25 per tonne of CO₂, rising to EUR 55 in 2025. For biomethane this means a new advantage over natural gas.
The British company CNG Fuels, backed by GBP 80 million from Foresight Group, has opened five stations and plans at least 14 more. Once they open, the network will serve about 8,000 trucks a day.
In December 2020 Australia adopted the act on recycling and waste reduction, which introduces a phased waste export ban: glass from 1 January 2021, then plastics, tyres and paper.
On 16 December 2020 the Minister of Natural Resources Seamus O’Regan presented the Hydrogen Strategy for Canada: 32 recommendations, regional hubs and a climate neutrality horizon of 2050.
