The choice of upgrading technology depends on a dozen or so criteria: scale, heat, the CO₂ market, methane losses, local conditions. We propose a matrix with weights and a scoring example for your own use.
We show step by step how to convert the mass of bio-waste into biogas, methane and electricity, and why the original estimates with the figure of 128 TWh were wrong by an order of magnitude.
Which measurements are essential at a biogas plant, how to build a SCADA system, which alarms to set and how to use the data for optimisation and process diagnostics.
The Act of 29 September 2022 implements in Poland Regulation (EU) 2019/1009 on fertilising products: a register of microbial fertilisers, market surveillance and penalties. It enters into force on 3 December 2022.
The regulation of the Minister of Climate and Environment published on 16 November 2022 introduces conditions for combustion waste to lose waste status: ashes, slags and synthetic gypsum from the power sector. It will apply from 1 December 2022.
At the COP27 climate summit in Sharm el-Sheikh methane was one of the main topics. On 11 November the American EPA proposed tightening methane rules, and UNEP launched a leak detection system.
In the auction of 25 October 2022 the Spanish ministry awarded 146 MW of biomass; the weighted price was EUR 93.09/MWh, ranging from EUR 72.38 to 108.19/MWh.
The Minister of Climate's regulation of 31 October 2022 sets reference prices in the RES auctions: among others PLN 785/MWh for agricultural biogas plants below 500 kW and PLN 920/MWh in cogeneration.
A municipal waste incineration plant is a recovery installation (R1) if its energy efficiency exceeds 0.60 or 0.65; otherwise it is disposal (D10). We give the formula and a worked example.
On 27 October 2022 Parliament and the Council agreed CO₂ standards for cars: a 100% emission reduction for new cars and vans from 2035. This is the end of new combustion-engine cars, including those running on biomethane.
On 26 October 2022 Italy published MITE Decree No 340 of 15 September 2022 on support for biomethane: EUR 1.7 billion from the PNRR and tariffs for installations injecting biomethane into the grid.
On 26 October 2022 the European Commission proposed a revision of the Urban Wastewater Treatment Directive. The proposal envisages energy neutrality of the sector, including energy production from sewage sludge biogas.
On 20 October 2022 Ecogas officially opened the Reporoa plant – according to the company the country's first commercial-scale anaerobic digestion plant for food waste, with a throughput of 75,000 t per year.
In mid-September 2022 the spot price of LGCs in Australia exceeded AUD 70, for the first time since November 2015. By the end of the quarter it had fallen to AUD 64.25.
In October 2022 the Australian government announced that it was joining the Global Methane Pledge, a target of cutting methane emissions by 30% by 2030, with no taxes or charges on livestock farming.
TTF is the European reference point for gas prices, quoted in EUR/MWh. We explain what a front-month contract means, how to convert prices to m³ and why biomethane is sold at a premium.
Drying is a way of using surplus CHP heat seasonally. We compare drying wood, grain and the solid fraction of digestate: heat demand and risks.
On 17 October 2022 bp announced its intention to acquire the American renewable natural gas producer Archaea Energy for about USD 4.1 billion. It is one of the largest transactions in the biogas sector.
The regulator ERC announced the FiT rules for 2022–2030 on 27 September 2022. Biogas from wastewater and waste receives 2.0724 baht/kWh and is given priority for grid connection.
On 28 September 2022 the European Commission and industry leaders launched the Biomethane Industrial Partnership (BIP), a cooperation platform intended to help reach the target of 35 billion m³ of biomethane by 2030.
A 2018 study assessed the methane potential of coffee processing waste in Ethiopia: from about 31 NmL CH₄/g VS (parchment) to about 295 (mucilage). We add the context of research on water hyacinth.
On 27 September 2022 Baltic Pipe, a pipeline with a capacity of 10 billion m³ a year from Denmark to Poland, was officially opened. For the biomethane industry it is also a link to a system in which renewable gas makes up a large part of the mix.
Shops over 250 m² where food accounts for at least half of turnover must hand food over to non-governmental organisations and pay the food waste fee. We explain the rules, deadlines and the fate of food that cannot be saved.
An ORC module converts low-temperature heat into electricity with low efficiency. We explain the operating principle, realistic yields, costs and when it makes sense.
