A new company named HomeBiogas is set to become a big player in the anaerobic digestion industry, but tailored to home biogas requirements. For them, is all about producing biogas in the home, or more accurately outside in the yard! Home biogas is widely produced in developing regions of the world. However, in the last couple of years entrepreneurs have started to produce well-designed home anaerobic digestion plants for single homes.
The feedstock chosen is kitchen scraps and garden waste. In particular Israeli startup Home Biogas has developed a relatively affordable home-sized biogas unit that allows people to convert their own waste into fuel. In Israel, temperatures get quite hot in summer but where winter lows have included snowfall it is not the best location due to the cold winters. Reportedly, even Northern California winters can be cold enough to make the bacteria stop producing if HomeBiogas is outside. Nevertheless, the start-up company Eco-gas Home Biogas has launched commercial biodigesters for the home and small institution.
Until now nobody has taken on the high-tech renewable energy technologies with a main-stream AD product. But, there is a strong argument for their unique business offer of low cost renewable energy. Solar panels are expensive. This is even more true, now that solar panels will not be supported by the UK government for new installations after the end of March 2018. Due to the cessation of the UK Renewable Heat Incentive.
Although the cost of each solar panel has dropped by about 30% in the UK, in 2017-18 even before the withdrawal of the subsidy for new solar panels, an average solar panel installation for a household would take 10 – 12 years to pay back the initial investment in solar panels.
In addition to the lower upfront cost of anaerobic digestion, home biogas does not require a grid-tie or any type of energy storage, as energy is stored in gas form and used on-demand when needed. on this basis home biogas is certainly worth looking at, discussed in the remaining part of this article.
A Closer Look at the HomeBiogas Biogas Plant Renewable Energy System
Homebiogas provides anaerobic digesters that convert kitchen waste and animal manure into cooking gas and liquid fertilizer. According to the company information the standard AD plant offered which is simply called “Homebiogas” can use up to 6 liters (6 qt) of food waste or up to 15 liters (15 qt) of animal manure per day. This is certainly more than an average UK family would produce in a day, and hence the HomeBiogas can instead be a community biogas project, where residents living in the same block can dispose their food waste into the community HomeBiogas system. The benefits from that could be in return, that they might get a supply of the digesters gas output piped into their homes. It is hard to see how this might physically be installed, for an average apartment block, it could be done at least in theory. HomeBiogas state that their digesters can be used in an urban environment, and located on rooftops.
On average, HomeBiogas can produce clean gas for up to 3 hours of cooking and 5-10 litres of clean natural liquid fertilizer daily. So, the output is quite definately a worthwhile amount of fuel to have and to use in te home. But, one advantage should also be to reduce food waste. Food waste is a huge problem in the UK, so it could be argued that a method to produce renewable energy, and gain value from food waste, should be a candidate for government financial assistance. But, on the other hand, using any biogas digester may not be effective in reducing food waste. That’s because people might use the HomeBiogas system as a reason to not reduce the amount of food wasted, as they may tend to produce more. The more food waste the system is fed with, the more HomeBiogas can turn it into useful energy.
It claims to be a socially oriented company that cares about spreading biogas technology to all. HomeBiogas is based in Beit Yanai, Israel. As a new company they only manufacture digesters of a small size as backyard appliances that convert organic waste into cooking gas and liquid fertilizer. No doubt larger models will emerge from them at some future date.
HomeBiogas can provide between 5-10 liters of top quality natural fertilizer each day.
Not everyone is going to find the output useful, normally called digestate it needs to be disposed of responsibly. If everyone with a home digester lived in flats and had no use for the fertilizer, it might get flushed down toilets. This would put a large and unwanted burden on sewage treatment plants.
Having already crowdfunded one backyard home biogas system that’s now being used in more than 1,000 homes worldwide, HomeBiogas’, current model is their second kickstarter focused on bringing a redesigned, more efficient and lower cost version to mass production. They say that they subsidize a percentage of shipping cost to give you, the consumer, the lowest possible shipping price.
In addition to the biogas plant, a Chinese company Puxin provides the accessories you will need including a biogas storage and transport bag.
