Sunfire puts high-temperature electrolyzer at Neste’s refinery to create green hydrogen

Sunfire is putting in the first multi-megawatt high-temperature electrolyzer in the world as part of the MultiPLHY project at Neste’s renewable products refinery in Rotterdam to create green hydrogen.

The business has already delivered the first two electrolysis modules, revolutionizing the market with new technological standards. Energy-intensive industries are implementing innovative cleantech solutions to meet their lofty sustainability goals. In light of this, one of the most promising ways to replace fossil fuels and cut CO2 emissions is electrolysis for the production of green hydrogen.

The goal of Neste, the largest producer of renewable diesel, sustainable feedstock for plastics, and sustainable aviation fuel in the world, is to achieve carbon neutral production by 2035. The company’s primary research and development focus areas are renewable hydrogen and Power-to-X technologies. Neste has recognized the future potential of high-temperature electrolysis solutions and is closely monitoring the advancement of various electrolysis technologies.

As a result, Sunfire’s 2.6 MW high-temperature electrolyzer will be installed at Neste’s renewable products refinery in Rotterdam as part of the EU-funded demonstration project MultiPLHY (Netherlands). The electrolyzer is a cutting-edge piece of equipment designed to create green hydrogen using water and renewable energy sources.

Construction work is already well underway, and Sunfire, one of the top producers of electrolysis equipment, has just shipped to Rotterdam the first two modules that make up its electrolysis system.

The business will set up twelve electrolysis modules altogether on the property, making it the largest high-temperature electrolyzer ever installed in an industrial setting. It runs at 850 °C and is based on Sunfire’s ground-breaking SOEC (solid oxide electrolysis cell) technology. The electrolyzer converts water steam to hydrogen with the highest conversion efficiencies by using industrial off-heat. The most effective electrolysis method available is Sunfire’s SOEC technology because the steam lowers the need for electricity.

The high-temperature electrolyzer will be produced on-site alongside other renewable products as part of Neste’s refinery processes. The electrolyzer will produce more than 60 kg of green hydrogen per hour once it is fully operational, which is anticipated to happen in early 2023.

The MultiPLHY consortium also includes ENGIE, the SMS-group company Paul Wurth, the French research institute CEA, and Neste and Sunfire.
