Decarbonising Paper Production - Replacing Natural Gas with Geothermal Steam

post-image
The paper industry is energy-intensive. According to the EIA, the industry consumed 1483.2 trillion British thermal units (Btu) of energy in 2019.  At the same time, the CO2 emissions of the paper industry reached 48 million tons. Utilising renewable energy is a well established way to try to reduce the emissions footprint of processing steps reliant on electricity.  But replacing natural gas needed for high temperature drying is harder. In what could well be a world-first, a NZ company is replacing natural gas in its drying hood with geothermal steam instead. https://www.eeca.govt.nz/about/news-and-corporate/news/essitys-groundbreaking-geothermal-project-a-world-first/
