A power purchase agreement (PPA) has been signed between gas and engineering company, BOC, a subsidiary of Linde plc, and energy from waste facility Avertas Energy and Shell Energy.

The 5-year agreement with Avertas Energy will contribute to BOC reducing its greenhouse gas emissions nationally by 16% following the purchase of large-scale generation certificates from the Kwinana-based energy from waste facility starting 1st January 2023.

Another factor in reducing GHG emissions is the energy retail agreement with Shell Energy. Under this, BOC will start receiving electricity for its Kwinana and Canningvale sites from mid-2022.

Speaking about the deal, John Evans, Managing Director, BOC South Pacific, said that this was a significant step forward in achieving BOC’s sustainability goals to achieve a 35% reduction in GHG emissions by 2028 and support long-term decarbonisation across its customer base.

He continued, “BOC is proud to be partnering with Avertas Energy and Shell Energy on this significant power purchase agreement that reduces BOC’s greenhouse gas emissions by 16% and supports the development of a world-leading energy from waste facility.”

“We look forward to offering our customers the opportunity to decarbonise their operations, with carbon dioxide and liquid nitrogen a critical product for many food and beverage applications including modified atmosphere packaging, cryogenic freezing and carbonating drinks.”

Under the agreement, BOC purchased enough certificates that all CO2 and liquid nitrogen supplied by BOC to the food and beverage sector is able to be produced by 100% renewable electricity starting from 2023.

Frank Smith, CEO, Avertas Energy, said, “We are pleased to be able to support BOC on its decarbonisation journey.”

With BOC intending to achieve a 35% reduction in GHG emissions by 2028, Greg Joiner, CEO, Shell Energy Australia, said the company was proud to support BOC’s sustainability goals, and to assist the decarbonisations of Australia’s manufacturing sector.

He also said, “Designing and delivering products and services that help large energy users decarbonise is a key focus for us as we assemble the building blocks of a cleaner energy system in Australia.”

A similar agreement was made between BOC and the New Zealand Environmental Certificate Scheme and Kea Energy solar farm earlier this year. The agreement permitted BOC to prvide green hydrogen to its New Zealand customers including NZ Steel.

Along with its other renewable energy ventures, Avertas Energy intend to divert 400,000 tonnes per annum of waste from landfill and use it to produce around 38MW of reliable baseload energy.
