New Zealand is set to establish its first large-scale biomass torrefaction facility in the Central North Island, a project led by Carbona. This significant initiative underscores the country’s commitment to a sustainable, low-emissions energy future while fostering regional economic growth.
With an annual production capacity of 180,000 tonnes of torrefied biomass, the facility aims to assist New Zealand in meeting its climate goals, including achieving net zero carbon emissions by 2050. The torrefied biomass will serve as a viable alternative to coal, with discussions ongoing with Genesis Energy to evaluate its use for the Huntly Power Station.
Torrefied biomass stands out for its 30% higher energy density compared to traditional wood pellets. According to David McGregor, director at Carbona, its lower volatile content and hydrophobic properties make it ideal for use in existing coal-fired boilers, easing the transition from coal while allowing for outdoor storage and improved handling.
Carbona has partnered with technology leaders Polytechnik and Andritz, who bring proven expertise from their recent commissioning of a similar facility in Finland. The collaboration positions New Zealand at the forefront of biomass innovations, enhancing both domestic applications and international market prospects.
Demand for torrefied biomass is soaring worldwide. Within New Zealand, sustainable demand could exceed 1 million tonnes, offering substantial opportunities for growth.
The design phase is anticipated to begin in mid-2025, construction in 2026, and commissioning by late 2027. This paves the way for commercial deliveries in early 2028. The biomass torrefaction facility is projected to save approximately 439,000 tCO2e annually, significantly contributing to the country’s emissions reduction strategies and reinforcing New Zealand’s leadership in renewable energy innovation.
