As 2025 comes to a close, clean energy is actively displacing fossil fuels across power grids, industry, and infrastructure. Governments, corporates, and utilities around the world are driving large-scale adoption, embedding clean energy into electricity systems, transport fuels, and industrial processes at a pace not seen before.
By late 2025, Australia’s National Electricity Market (NEM) had reached a clear inflection point. Renewable energy was consistently supplying around 43% of total electricity demand, with daily peaks approaching 80% during periods of strong solar and wind output.
This shift was driven by continued growth in large-scale solar and wind generation, alongside a rapid expansion in grid-scale battery storage, which improved reliability and enabled higher renewable penetration.
Across the sector, 2025 was marked by real technical advances in efficiency, durability, and system integration. These improvements strengthened performance, reduced costs, and accelerated the rollout of clean energy across power, fuels, and industrial systems.
Industry Innovations Throughout 2025
- Progress in Low-Carbon Ammonia Production: Throughout 2025, electrochemical and plasma-based ammonia production methods advanced through published research and pilot testing. These approaches showed potential to reduce emissions and energy use compared to conventional ammonia production, particularly when paired with renewable electricity.
- Plastic-to-Energy Conversion Became More Efficient: Across 2025, advances in catalytic depolymerisation enabled mixed plastic waste to be converted into fuels and chemical feedstocks at lower temperatures. These improvements reduced energy requirements and improved process economics.
- Microwave-Based Plastic-to-Energy Systems Advanced: Microwave-assisted reactors gained traction in 2025, offering faster reaction times and improved control compared to conventional thermal processes. This helped improve yields and reduce energy losses in plastic-to-energy applications.
- Industrial Waste Heat Integrated into Clean Energy Systems: During 2025, pilot projects increasingly integrated waste heat from heavy industry into clean fuel and energy systems. This reduced electricity demand and improved overall efficiency.
- Liquid Air Energy Storage Expanded Beyond the Grid: By the end of 2025, liquid air energy storage systems were being used not only for grid support, but also for data centre cooling and waste heat recovery, demonstrating broader commercial applications.
- Direct Seawater Electrolysis Reached Practical Demonstration: In 2025, new catalyst coatings enabled hydrogen production directly from seawater without full desalination. This reduced cost and complexity for coastal clean energy projects.
- More Efficient CO₂-to-Fuel Catalysts: During 2025, researchers demonstrated improved copper-based catalysts capable of converting carbon dioxide into fuel intermediates at lower temperatures and with higher efficiency. These advances reduced energy intensity and improved system stability, supporting the long-term viability of CO₂-derived clean fuels.
