Mitsubishi Power has reported successful completion and handover of a pioneering hydrogen fuel conversion project at the Alexandria National Refining and Petrochemicals Company (ANRPC) refinery in Egypt. The project is considered the first industrial use of hydrogen as fuel in an industrial boiler in Egypt and the MENA region.
Under the terms of the full turnkey contract, announced in 2022, Mitsubishi Power undertook the design, engineering, and installation scope of the boiler rehabilitation project, including

conversion of the 100-ton-per-hour main boiler from heavy fuel oil and natural gas to 100% hydrogen fuel.
According to Mitsubishi Power the project “reflects hydrogen’s enormous potential as a clean energy source in Egypt’s industrial sector.”

Valmet BFB boiler projects at Salmisaari and Örtofta
Valmet and Helen Oy have signed a comprehensive four-year service agreement aimed at ensuring good long-term performance at the newly converted wood-pellet-fired K7 bubbling fluidised bed boiler installed in Helen’s Salmisaari power plant in Helsinki, Finland. Valmet carried out the conversion of the Salmisaari K7 boiler, originally coal-fired, to bubbling fluidised bed. The project was handed over to the power plant owner/operator in March 2025, marking another milestone towards Helen’s goal of carbon-neutral power and heat production and representing a major step in phasing out coal in favour of clean energy. The service agreement aims to ensure long-term operational reliability, safety, and optimal performance of the entire plant through proactive and planned maintenance services and process support.
“We have had excellent co-operation with Valmet, and we are pleased to continue our partnership with a new agreement for the Salmisaari K7 boiler. At Salmisaari, Valmet will have an important role in providing operational services in close co-operation with Helen’s personnel,” said Jari Rahtu, Asset Manager, Helen Salmisaari.
“The new service agreement was tailored together with the customer to meet their specific needs. As the BFB boiler and flue gas condensing systems are new technologies at the Salmisaari plant, the agreement provides targeted support to help ensure their smooth integration and reliable operation. We value the opportunity to continue our collaboration at every stage of Helen’s transition to sustainable energy – from delivering the boiler conversion to providing support through the tailored service agreement,” said Sampo Smolander, Sales Manager, Pulp, Energy & Circularity Finland, Valmet.
The service agreement includes annual inspections and maintenance of specified parts in the K7 plant, covering boiler pressure parts, flue gas cleaning system and condensing unit, condensate treatment system and auxiliary equipment. It also includes shutdown planning, participating in maintenance and spare parts management planning and on-site as well as remote process support via Valmet industrial internet services.
Bubbling fluidised bed boiler technology is also the focus of a recent order Valmet has received from Kraftringen Energi for its new combined heat and power plant to be built in Örtofta, Eslöv municipality in Skåne, Sweden. As well as the bubbling fluidised bed boiler itself, the Valmet scope also includes flue gas handling equipment. The new CHP plant, which will be built next to an existing CHP installation, will replace aging facilities and ensure a reliable supply of district heating, says Valmet, securing heat and hot water for large parts of central and western Skåne. By nearly doubling the production capacity in Örtofta, Kraftringen Energi will be able to deliver an additional 25 MWe of power. In addition, the new plant will bring other significant benefits, such as increased delivery of process steam and localised, predictable power production.
The CHP plant will feature Valmet’s flue gas treatment system with integrated heat recovery, which will feed additional energy into the district heating network, enhancing both efficiency and sustainability. The system is also designed with future readiness in mind, enabling smooth integration of carbon capture technology if required.
The project is the largest investment in energy production in Skåne in the past decade and will significantly enhance the region’s energy security. Installation is scheduled to start in June 2026, and the plant is scheduled to be operational in 2028.
“This delivery showcases state-of-the-art flue gas treatment technology that ensures very low emission levels while maximising energy recovery to the district heating network,” said Lari-Matti Kuvaja, Director, Environmental Solutions, Valmet. “Carbon capture readiness has been carefully taken into account in the design, making the system well-prepared for future climate requirements. We’re pleased to support Kraftringen Energi with a solution that combines immediate environmental performance with long-term adaptability.”
As well as the BFB boiler, Valmet’s scope includes auxiliary equipment and the boiler building, plus a Valmet flue gas cleaning system consisting of bag house filter, selective catalytic reduction for removal of nitrogen oxides, combustion air moisturiser, flue gas condenser, and condensate treatment sytems.
Kraftringen is owned by the municipalities of Lund, Eslöv, Hörby, and Lomma.
