Purple bacteria produce H₂ from organic acids in the light, using nitrogenase. We explain the mechanism, conditions, hybrid systems with dark fermentation and the real barriers to scaling up.
An agricultural biogas plant usually does not need a URE licence, only an entry in the KOWR register. Check when a licence is necessary: capacity, type of biogas, heat and gas trading.
On 23 March 2022 the NDRC and the NEA published a medium- and long-term plan for developing the hydrogen industry: by 2025 about 50,000 fuel cell vehicles and 100–200 thousand t of green hydrogen a year.
On 21 March 2022 Decree 11.003 established the Federal Strategy to Encourage the Sustainable Use of Biogas and Biomethane, and Portaria MMA 71/2022 set up the National Methane Reduction Programme — Metano Zero.
When biological desulphurisation is not enough, iron oxide beds, alkaline scrubbers and activated carbon are used. A comparison of methods, an example calculation of bed life and the rules for safe replacement.
On 8 March 2022 the European Commission proposed reducing EU demand for Russian gas by two thirds already this year. Among the measures – accelerating renewable gases, including biomethane.
On 7 March 2022 gas quotations at the Dutch TTF exchange reached an all-time high, exceeding €300/MWh during the session. For biogas plants this is an opportunity, but also a warning about costs.
On 3 March 2022 the International Energy Agency presented a 10-point plan that could cut imports of Russian gas to the EU by more than a third within a year. Biogas and biomethane are one of its elements.
On 28 February 2022 the IPCC published Part II of its Sixth Assessment Report – on climate change impacts and adaptation. Its conclusions on agriculture and food systems also affect the biogas industry.
A virtual pipeline is the delivery of compressed or liquefied biomethane by road. We explain the arrangement, capacities, transport costs per kilometre and the profitability limit.
On 24 February 2022 Russia began its invasion of Ukraine, and gas prices in Europe rose sharply. For biogas and biomethane this event shifts the debate from climate to security of supply.
On 19 February 2022 Prime Minister Modi remotely opened in Indore a bio-CNG plant processing 550 t of segregated organic waste per day. The gas is to power, among others, city buses.
On 27 January 2022 the Commission adopted the CEEAG guidelines to replace the 2014 EEAG. They cover renewables, cogeneration and heating, and support is to be based on competitive tenders.
Is a pyrolysis or gasification installation a waste incinerator? It depends on whether the resulting substances are then burned. We discuss definitions, permits, the IED and the status of oil and char.
The South African cabinet approved the Hydrogen Society Roadmap in September 2021, and Minister Nzimande formally presented it on 17 February 2022. The roadmap sets out 70 priority actions.
Results of the auction of 20 December 2021: of eight bids, six concerned biomass plants. The support budget was HUF 17 billion a year and 870 GWh of energy.
The cheapest way of lowering H₂S: a small dose of air into the digester headspace and bacteria that oxidise sulphides. How to choose the amount of air, how to control it and what to avoid.
On 2 February 2022 the European Commission adopted a complementary act to the taxonomy, which allows some investments in natural gas and nuclear energy to be regarded as transitional. What does this mean for renewable gases?
On 20 January 2022 FortisBC applied to the regulator to supply 100% renewable gas to all new homes; the company is on track to exceed its target of 15% renewable gas by 2030.
The act of 26 January 2022 caps gas prices for households and some institutions in 2022. Sellers receive compensation from a fund fed, among other things, by revenue from ETS allowance auctions.
The EU database (UDB) is meant to track liquid and gaseous renewable fuels from production to sale. We explain the purpose, the scope of data and the significance for biomethane producers.
Lei 14.300 of 6 January 2022 introduces a legal framework for distributed micro- and mini-generation in Brazil: net metering with the grid and gradual charges for use of the grid.
What does an investment in a biomethane plant and its operating costs consist of? We show the structure of CAPEX and OPEX and a calculation example without invented prices, with explicit assumptions.
Until the end of 2021, new renewable installations, including those running on biogas and biomass, could join the joint Norwegian-Swedish certificate system. The system is due to run until 2035.
