In April 2020, Re-Gas Energy (formally RKE BioGroup) successfully acquired the Herriard Bio Power AD Plant from Barfoots of Botley.
Herriard Bio Power, located in Basingstoke, converts food waste and crops into biogas which exports over 10 million kWh of clean, green energy every year through a 1.2MW CHP engine – enough to power 2,200 homes.
The plant is fed with approx. 5,000 tonnes of maize / rye crops from the surrounding estate. The main amount of biogas however comes from 20,000 tonnes of food waste. The food waste is sourced from commercial and domestic waste streams.
The plant produces around 20,000 tonnes of environmentally friendly, premium quality, nutrient–rich organic fertiliser each year. The digestate bio-fertiliser is rich in Nitrogen (N), Phosphate (P) and Potassium (K). The digestate is pumped straight from the AD plant, via a pasteurisation process and into our on-site lagoon and then onto surrounding farmland, via underground piping network. The use of carbon-intensive synthetic fertiliser is greatly reduced through this process.
In July 2021, with the support of its investors and funding partners, Re-Gas Energy began construction work on the “Phase 2” plant expansion which will enable production of over 8,400 Nm3 per day of biomethane.
The Biomethane which will be transported via CNG road tanker to a gas injection point located at Portsdown Hill, Portsmouth. This is referred to as the “virtual pipeline” method.
The existing plant, “phase 1”, will continue to feed a CHP engine producing electricity & for export to the grid and heat for the site.
The plant expansion is due to be completed by March 2022.
