Animal farm powers village

Pigs and cows along with chickens are recruited to power a village. The new animal farm AD biogas plant commissioned today demonstrates how rural villages will be powered by local energy.

The future of community energy is being pioneered near the small English village of Hatherop where a power station using biogas or 'digester gas' was commissioned today. Powered by agricultural biomass, including chicken litter, cow dung and pig slurry, residents benefit from this low cost alternative to oil, coal and foreign gas.

Hatherop is one of the first villages in the United Kingdom to benefit from power derived from chicken litter, cow manure and pig slurry.
This sustainable energy technology allows production of local power, called 'distributed energy.' This type of energy production reduces energy waste, reliance on fossil fuels, energy imports and costs. This is because the plant is fuelled by naturally decaying biological matter.

As well as energy security, this technology brings low cost heat, electricity and new jobs to rural areas. The process has an added benefit by capturing smells normally generated by farms in a dome and burning them in the energy production process. Local farms deliver animal waste and crops, such as maize and grass, as the fuel for the plant. After the process of extracting the methane from the feed stock, farmers will use the residual, called 'digestate', as fertiliser for new crops for food and animal feed.

Looking like a giant muffin, the plant will produce 350 kilowatts of electricity per hour, enough to supply 175 homes with electricity.

Local energy delivers local benefits

An AD plant on a farm delivers socio-economic benefits in rural areas: The farmer earns money from his waste, the plant reduces energy and fertiliser costs while stabilising income. Adopted widely, more jobs are created in run plants, food will cost less and farmers are more competitive. Jeremy Iles and James Hart are the tenant farmers that built and own the biogas plant. James Hart comments: “I am delighted with the plant so far and look forward to reducing our emissions and agricultural costs while giving sustainable energy a boost.”

The owners will benefit from free heat for animals, grain drying and housing; previously a significant expense. But there are other environmental benefits from the biogas process that reduce costs for the farmer. The biogas plant encloses and traps any smell from the waste and burns it in a combined heat and power (CHP) plant. The leftover liquid waste from the biogas plant, known as ‘digestate’ can be used on the farm as a powerful fertiliser that normally is a major cost to farmers and the environment. Normal fertiliser production uses large amounts of fossil fuel, emits significant quantities of CO2 and the finished product is transported over great distances to farmers. Now the fertiliser is produced locally at the power plant, there is no necessity in importing it from the US or the Middle East. Jeremy Iles, the other plant partner, says: “We are happy to minimise the impact of our agricultural operations on our neighbours and rural community.

The project was funded by a grant from the Rural Development Programme for England (RDPE) and the project is part financed by the European Agricultural Fund for European Development 2007-2013: Europe Investing in Rural Areas.

James Hart concludes: “It should be acknowledged that the project is being delivered through the South West RDA with DEFRA as the Managing Authority and we are grateful for their help.”

World leading plant

Alfagy was chosen as the main Combined Heat and Power (CHP) supplier after a competition against leading manufacturers such as GE Energy, Jenbacher, MWM and MAN. "As the UK is 30 years behind continental Europe in energy efficiency, this is an important demonstration of a sustainable energy future", said Peter Kindt, the chairman of Alfagy.

"What makes this project exciting is that farmers deliver energy to the local community, a new business model for farmers,” adds Peter Kindt.

The plant started generating power for the first time on 5 April 2011.

The AD plant and inclusion of the CHP was designed by Frank Kenny of Water and Waste Services Ltd. He also contributed significantly to the project management and comments “It has been a great pleasure working with James and Jeremy. The plant start up has been without any hitches and by using WWS’s process expertise and design, a very efficient plant has been delivered that is a model to reduce Greenhouse Gases across the agricultural sector.”

Other European farmers are now considering similar projects.

About Hatherop

The village of Hatherop has just over 50 households with some 290 inhabitants. The Domesday Book of 1086 lists Hatherop as Etherope, derived from the Old English hēah and throp meaning "high outlying farmstead". The village and parish adjoin the parkland of Williamstrip, a 17th-century country house that was the seat of Michael Hicks Beach, the first Earl St Aldwyn. The 3,850-acre (1,560 ha) Hatherop Estate was acquired by the trustees of the Ernest Cook Trust in 2002 from the Bazley family, who had owned the estate for more than 130 years. Hatherop lies in the southern part of the Cotswolds, a range of hills designated an Area of Outstanding Natural Beauty, and is approximately 30 miles (48 km) south-east of Gloucester. Nearby, to the west of Hatherop is the River Coln which flows through the Cotswolds.

About Anaerobic Digestion

The Anaerobic Digestion (AD) process is a great success on the European continent and there are more than 5,000 AD plants operating in northern Europe. AD happens where any organic material decomposes and methane-rich gas – known as ‘biogas’ – is released. Biogas can be burnt in a generator to produce renewable electricity and heat. After the methane and other gasses are extracted, a balanced, fibrous natural fertiliser called ‘digestate’ is spread on land as a fertiliser. On farms, the whole process uses normal farming techniques and equipment to deliver the feedstock. Food and animal waste from horses, chickens, turkeys, pigs and cows are useful for biogas production. Water companies also use biogas extracted from return water to generate heat and power. The biogas created is used to fuel a Combined Heat and Power unit to produce electricity which is then exported to the National Grid. Of all renewable energy solutions, AD creates far more long term jobs, supports the rural economy and captures renewable energy. The process uses locally produced crops and crop residues as well as a wide variety of wastes. Compared to other alternative renewable energy generators, such as wind turbines, it has significantly less visual impact. The bio-product of the plant is returned to the surrounding land as fertiliser to support the growth of the following year’s crops – reducing the need for carbon-intensive industrial fertilisers, which are a major source of greenhouse gas emissions. It also smells far less.

The food industry and farmers have it easy when it comes to energy production. The energy sources is all around and only need to be channeled into a process using:

  • Food waste
  • Grasses
  • Cereals
  • Chicken manure
  • Horse excrement
  • Cow manure
  • Organic production waste

All these can be used for biogas production which is then turned into heat and power. This is a great sustainable business model which cuts cost and increase competitiveness in the core business. Meanwhile, operational security is increased.
