  • The City That Turns Human Waste into Clean Fuel

    Innovative projects in Germany and Denmark are transforming sewage gases into valuable resources like methanol and green hydrogen, offering sustainable solutions for industries and rural communities. The Mannheim 001 pilot project in Germany is producing methanol from biogas at a wastewater treatment plant, with plans for upscaling production, while the Kassø e-methanol facility in Denmark showcases successful large-scale investment in this area. These initiatives not only aim to decarbonize industries and reduce energy consumption in sewage treatment plants but also have the potential to benefit rural communities by cutting waste disposal costs and generating renewable power. Despite obstacles such as regulations and lack of legal frameworks, the global potential of scaling sewage-to-methanol could have significant climate and air quality benefits, particularly in meeting the fuel demand of the global shipping sector striving for net-zero greenhouse gas emissions by 2050.

  • Australia doesn’t have to choose between energy affordability and emission reductions

    IEEFA has found that improving energy affordability in Australia does not have to be incompatible with emissions reduction targets. The country's aging coal fleet and network assets need to be replaced, with renewables backed by storage and transmission being the most cost-effective option. Gas-based generation has become increasingly uncompetitive, with high prices and declining consumption. Contrary to misconceptions, renewables have not been driving electricity prices up, with high gas and coal prices, coal outages, and network costs being the main factors. Faster approval processes and better market regulations are needed to ensure a smooth transition to cleaner energy sources. Reforms to improve competition, allow distributed energy resources to compete, and promote energy efficiency, electrification, and flexible demand are key to lowering household energy bills. Transitioning to modern electric alternatives, such as heaters and hot water systems, along with solar and battery systems, can significantly reduce costs. Industrial energy efficiency and electrification also offer major savings. The key pathways to improve energy affordability are aligned with net zero emissions goals, emphasizing the need for accelerated deployment of renewables, energy efficiency, and electrification. The narrative that lowering bills and cutting emissions are mutually exclusive is false.

  • Community-based energy trading system for home solar-plus-storage

    A cloud-based system developed by Washington State University allows for local energy trading and sharing within neighborhoods, resulting in potential cost savings of up to 12% over a five-day test period. The system, tested in collaboration with a local utility network, highlights the importance of coordinated operation at the distribution level in the changing electricity industry landscape. Published in the journal IEEE Transactions on Industry Applications, the research paper presents a community-based transactive coordination mechanism for enabling grid-edge systems, with the ability to reduce energy costs by up to 12% in communities with solar and battery energy storage systems.

  • New transmission towers are crucial for renewables – but contentious. Here’s where they should go

    Solar and wind provide 99% of new generating capacity in Australia, with renewables supplying over 40% of power to the main grid. Australia will need six times as much solar and wind to reach net zero through electrification. Building new transmission corridors is necessary, but existing lines are not sufficient. The grid operator plans to build 10,000 km of new transmission lines, with a focus on high-voltage direct current lines to unlock renewable resources. Optimizing new transmission corridors is crucial for Australia's future grid. A study has identified potential high-voltage direct current (HVDC) transmission line corridors in Australia to connect renewable resources in northern regions to population centers in the southeast. These corridors could significantly reduce wholesale electricity costs by 8-18%. Energy storage schemes like Snowy 2.0 could also help cover seasonal gaps locally. Community buy-in is crucial for such projects, and the benefits of unlocking renewables can be quantified for each local government area. Policymakers should prioritize building these transmission corridors to meet new demand and consider pairing them with pumped-hydro schemes. The article discusses the importance of energy storage in balancing variable renewable generation and maximizing the use of transmission lines. Cheng Cheng, a Senior Research Officer at the Australian National University, highlights the role of energy storage in the transition to a more sustainable energy system. This technology helps to ensure a reliable and stable energy supply while also reducing greenhouse gas emissions. Energy storage is a key component in achieving climate solutions and increasing the efficiency of renewable energy integration.
