After the memorandum of 10 June 2020 and Law 810-IX, Ukraine's green tariff for biogas and biomass applies to installations commissioned before 1 January 2023. The industry is protesting.
Communication COM(2020) 562 proposes a target of reducing net emissions by at least 55% by 2030 compared with 1990 and announces a review of the whole energy and climate legislation by June 2021.
Thailand developed biogas mainly alongside agri-food industry and farms. In October 2016, 412 MW of installations were operating, and the 2015 AEDP plan envisaged 600 MW from wastewater and manure and 680 MW from energy crops by 2036.
Acetate, propionate, butyrate and valerate are the everyday picture of the state of the process. We explain how to measure them, how to read the propionate-to-acetate ratio and when to react.
On 2 September 2020 the Latvian Cabinet of Ministers adopted two regulations replacing the 2009 and 2010 rules on mandatory energy purchase (obligātais iepirkums). From 2021 cogeneration and renewables are subject to uniform efficiency requirements.
On 8 September 2020 the French government announced a national low-carbon hydrogen strategy: EUR 7.2 billion of public support to 2030, of which EUR 2 billion in 2021–2022 under the recovery plan.
The President of the Polish Oil and Gas Company (PGNiG), Jerzy Kwieciński, announced a biomethane plant construction programme at the European Economic Congress in Katowice. The first installation was to start at the turn of 2020 and 2021.
The 2020 nitrates programme applies nationwide: a limit of 170 kg N/ha from natural fertilisers, application dates, tanks for 6 and 5 months, and documentation. What does this mean for digestate?
Methane slip is the part of the CH₄ from biogas that goes into the off-gas instead of the biomethane. We calculate how many tonnes of CO₂e and how many zloty this means, using a 500 m³/h installation as an example.
The President signed an amendment to the Act on Renewable Energy Sources that broadens the definition of energy wood from 1 October 2020 to the end of 2021. The Sejm passed it with 232 votes, and the Senate wanted to reject it.
Free ammonia (NH₃) inhibits methanogenesis. We explain the dependence on pH and temperature, show the calculation step by step and set out the remedial options.
In August 2020 construction began on the Ecogas plant in Reporoa, which is to process 75,000 t of food waste a year and supply heat and CO₂ to the T&G greenhouse.
On 28 July 2020 a 50 MW power plant made up of 114 modules of 440 kW each, fuelled by by-product hydrogen from the Hanwha Total petrochemical plant, was officially completed in Daesan.
Orlen Południe, H. Cegielski-Poznań, the National Support Centre for Agriculture (KOWR) and the Poznań University of Life Sciences signed a letter of intent on biogas plants on the 20 largest farms supervised by KOWR.
The European Commission approved Ireland's RESS scheme (SA.54683): strike-price auctions for 15 years, with an estimated budget of EUR 7.2–12.5 billion until 2025. For biogas this is a new mode after REFIT.
Biohydrogen is hydrogen from biomass or biogas, not from electrolysis. We explain the pathways: dark fermentation, photofermentation, biogas reforming and gasification, together with the real state of development.
Since 2020 waste records have been kept in BDO. We describe who prepares the KPO, what the carrier confirms, how the KEO, simplified records and the emergency mode work.
On 21 July 2020 EU leaders agreed the multiannual budget and Next Generation EU. A new source of revenue will be a levy of EUR 0.80 per kilogram of non-recycled plastic packaging waste.
Law 14.026/2020 amended the National Solid Waste Policy: new deadlines for closing lixões (open dumps) were set for 2021–2024, depending on the size of the municipality.
Too low a C/N leads to ammonia inhibition, too high to nitrogen deficiency. We show the range, an example mix balance and typical values for substrates.
In South Africa's main renewable energy auction programme bioenergy appeared only marginally: in window 3 a landfill gas bidder (18 MW) and a biomass bidder (16 MW) were selected. What does this say about the market?
Communication COM(2020) 301 sets three phases of hydrogen development in the EU, with a target of 40 GW of electrolysers and up to 10 million tonnes of renewable hydrogen by 2030. The European Clean Hydrogen Alliance was also created.
Communication COM(2020) 299 announces stronger links between electricity, heat and gas. Hydrogen, biofuels and biogas are named among the renewable fuels for sectors that are hard to electrify.
On 5 July 2020 the transposition deadline for Directives 2018/849–852 expired. The package introduces recycling targets of 55/60/65%, a landfill limit of 10% and an obligation to collect biowaste separately by the end of 2023.
