New biogas plant will utilise tapioca production waste

Aggreko, a global provider of mobile, modular power, is working with RE Power Group to produce renewable electricity from biogas in Thailand.

Aggreko is delivering 6MW of biogas-fuelled power to provide a 'flexible, fast and cost-efficient' way of scaling-up the biogas project and delivering cleaner energy for the region.

The plant’s feedstock is sourced from a tapioca factory. The wastewater and biomass are then captured in Thailand’s first and largest dual-feedstock anaerobic digester. The same tapioca factory has been purchasing biogas to substitute 18,000 litres per day of heavy fuel oil to dry its starch since August 2018. With a production capacity of 100,000m2 of biogas per day, the opportunity to convert biogas into power at the site is substantial.

“Two of Aggreko’s core strengths are flexibility and a rapid response time, which made us a perfect partner for RE Power Group to deliver an innovative power solution that met their unique needs,” said Bill Carrick, group product director at Aggreko.

“Converting waste gas not only has cost benefits for the customer, but also generates a much cleaner energy source for the wider region and has significantly reduced the facility’s carbon emissions. We are proud to be supporting such an innovative project that is so closely aligned with the UN’s Sustainable Development Goals, and look forward to continuing our relationship with RE Power Group to deliver both cost and carbon reductions over the coming years.”

Over the five-year contract, the new power solution is set to deliver a total reduction of three million tonnes of greenhouse gases, equivalent to removing 40,000 cars from circulation. The project is also saving RE Power Group $1 million (€924,000) in grid costs annually.

Gustaf Godenhielm, co-founder of RE Power Group, added: “By partnering with Aggreko, we were able to successfully scale up our operating biogas project by adding power generation capacity in record time and at significantly lower capex than expected. Beating our expectations, the gensets arrived in Thailand just three weeks after signing the contract. We’re really pleased that the bespoke solution Aggreko has put in place is already bearing fruit and we’re making positive progress towards our carbon reduction targets.”
