2023. Notably, this marked the first Biomass Mix-Firing test for a Supercritical type of boiler in Malaysia. The trial run demonstrated positive outcomes, showcasing observable reductions in emissions. Moving forward, further studies and actual tests will be conducted to assess the technical behaviour under increased concentrations, e.g. 3% to 5% of biomass and ammonia. This ongoing exploration is integral to refining and optimising our co-firing strategies for enhanced sustainability. Reducing Carbon Emissions We continue to accelerate the transition from a fossil-fuel-based energy mix to low-carbon energy sources such as hydrogen. Through strategic collaboration with IHI Corporation, we are working together to reduce carbon emissions in identified TNB coal-fired power plants. Our goal is to explore the practicality of using hydrogen in co-firing and conducting tests with different hydrogen concentrationsto achieve targeted emissions reductions. This collaboration focuses on both technical and commercial aspects, paving the way for a more sustainable energy future.

Building upon the initial TNB-PETRONAS MOU signed on 19 August 2022, the parties are advancing towards a Definitive Agreement for a Joint Feasibility Study focused on green hydrogen as a clean energy alternative. The collaborative study aims to provide a comprehensive understanding of commercial viability, considering factors such as the levelised cost of electricity (LCOE), levelised cost of hydrogen (LCOH), levelised cost
