We have said many times that the anaerobic digestion process makes green biogas profitable with a good ROI, but where is the proof of that?
Back in December 2012 when we first posted this article, we based our case on a “Utility Week” article here which announced that Anaerobic digestion and energy efficiency had won the first Green Investment Bank funds.
Green gas is a promising renewable energy form produced from organic material (biomass). The development of its generative processes along with its integration in energy systems will, no doubt, be vital for decarbonising the UK and reaching net-zero emissions. via selectra.co.uk
The UK's new Green Bank was able to invest in the AD industry, they had no doubt that biogas technology is green, and the article is copied below for you to read.
Read to the end of this post and you will find out why President George Washington is as shocked as he is, as shown on the $1 bill below!
Of course, our regular blog and newsletter readers will not need to be told that biogas and the energy and other by-products of the anaerobic digestion process are green, but hopefully, they will take some cheer from the very high profile this first Green Bank award gives to AD Plants.
If anyone in the UK needed any further convincing that anaerobic digestion was not fully supported by the UK government, at the current “post-covid” high energy prices, then surely this must go a long way to changing that opinion?
It is Green Biogas and it's Official!
So, read on and visit the news articles below for an in-depth understanding of this Green Bank funding:
Anaerobic digestion and energy efficiency win first Green Investment Bank funds
Utility Week Article Extract:
“28 November 2012. Anaerobic digestion and energy efficiency win first Green Investment Bank funds. An anaerobic digestion (AD) plant and an energy efficiency retrofit were the first projects to win funds as the Green Investment Bank (GIB) launched today.”
Here is another green biogas article link to articles on this same subject:
Anaerobic digestion plant was the Green Investment Bank's first!
“An anaerobic digestion plant in the North East of England is the first project to receive investment from the newly opened UK Green Investment Bank.”

Still on the green biogas theme but this time without the Green Investment Bank connection, we suggest the following item that may interest our readers:
Transforming waste into green energy
“Anaerobic waste water digestion technologies respond not only to industry's need to clean up the waste water it discharges to the environment, but also to the need for industry to break free from the cost and pollution of fossil fuels – and the …” via www.pacetoday.com.au
“Any factory with a biological waste stream or wastewater with high COD (Chemical Oxygen Demand) can use this technology to generate energy. Some companies making the investment have achieved payback within a year.”
(Note: Video is unrelated to payback period quoted above.)
Payback within a year. That's amazing, isn't it! Demonstrate that to investors and there won't be any need for a Green Investment Bank.
In fact, “green” gets a whole new meaning in that case, and it's nothing to do with the environment. No, the “green” of biogas which we shall see becomes the green of the note (dollar or “greenback”!).
That's what we were alluding to when we created today's graphic!
Green Gas Explained – In Depth
We say that not only is it green in the sense of it being an environmentally friendly form of energy and fertilizer production, but it also has many other “green” environmental benefits.
That green biogas is, genuinely green in the sense of it being sustainable can be shown by it being funded by “green” investment organisations.
Biogas – or biomethane – is produced when organic matter such as leftover food and agricultural waste is processed in an anaerobic digester (AD).
AD tanks let the waste break down in an environment free from oxygen. This allows methane gas to be produced, which is then extracted from the AD and injected into the gas grid.
Once it's in the grid, green biogas can be used in the same way as natural gas: it's burnt to heat our homes and cook our food.
What makes biogas carbon neutral?
Burning biomethane does release carbon dioxide. But, because it releases the same amount of carbon dioxide that the organic matter used to produce it absorbed while it grew, it doesn't break the carbon balance.
But when we extract and burn natural gas, we're reintroducing carbon dioxide that has been locked away for millions of years, from when the earth's atmosphere was different. This adds more carbon dioxide to our current atmosphere, breaks the carbon balance and contributes to global warming and climate change.
What's more, the material left over at the end of the AD process can be used as a natural, nutrient-rich fertiliser. Which will help grow plants and food that lead to the waste used to generate biogas – and the cycle goes on. via www.goodenergy.co.uk
What is Green Gas?
Green gas (or biomethane) is made from biodegradable materials which can then be used in the same way as energy from fossil fuels – to heat your home or cook with.
The biggest difference between green gas and traditional fossil fuel gas is that biomethane is renewable and virtually carbon neutral, so it doesn’t contribute towards climate change.
How is green gas made?
Green gas is made by turning organic matter (like plants or vegetables) into biomethane, through a process called anaerobic digestion.
Harvest the fuel source. Green biogas can be made from a number of biodegradable materials – in our case, we will use grass to create green gas.
Anaerobic digestion (AD) creates green biogas, along with a natural fertiliser – which can be used to improve soil quality, in place of harmful synthetic fertilisers.
The Creation, Success, and Sale of the UK Green Investment Bank: A Journey to a Low-Carbon Economy
The UK Green Investment Bank (GIB) was created in 2012 with the goal of promoting investment in renewable energy and low-carbon infrastructure projects in the United Kingdom. The bank was established by the UK government as a way to mobilize private sector investment in green projects, with the aim of accelerating the country's transition to a low-carbon economy.
The creation of the GIB was driven by a number of factors, including the UK's commitment to reducing greenhouse gas emissions, the need to meet renewable energy targets, and the potential economic benefits of transitioning to a low-carbon economy. The bank was designed to provide a source of funding for renewable energy and low-carbon projects that might not otherwise be able to secure financing from private investors.
The GIB was successful in achieving its objectives, investing over £16 billion in more than 100 green infrastructure projects across the UK, including wind farms, biomass power plants, and energy-efficient buildings. The bank was also credited with helping to create thousands of jobs and supporting the growth of the UK's green economy.
However, in 2015, the UK government announced its intention to privatize the GIB, citing the need to attract more private investment to support the bank's growth. This move was controversial, with some critics arguing that privatization would compromise the bank's mission and potentially undermine its impact.
In 2017, the GIB was sold to a consortium led by Macquarie Group, an Australian infrastructure investor, for £2.3 billion. The sale was met with mixed reactions, with some stakeholders expressing concern that the bank's green credentials might be compromised under private ownership.
Despite the sale, the GIB continues to operate as a green investment bank, with a focus on investing in renewable energy and low-carbon infrastructure projects in the UK and beyond. The bank's success has inspired the creation of similar institutions in other countries, such as the Green Investment Group in Australia and the Green Investment Fund in Ireland.
How Much of the UK Nation's Gas Could be Supplied?
In theory, we could produce 97% of domestic gas demand from grass (via a green biogas facility also known as a biogas plant or anaerobic digester) by 2035.
There’s huge potential for green gas to make a big contribution to reducing carbon emissions and building a more energy-independent Britain. via www.ecotricity.co.uk
