Summary of "Driving to Net Zero Industry Through Long Duration Energy Storage"

Core Content

Long Duration Energy Storage (LDES) technologies are essential for decarbonizing the industrial sector and achieving the Paris Climate Accord's 1.5°C pathway. These technologies can store and discharge energy for more than eight hours, using electrochemical, chemical, thermal, and mechanical storage media. They are already being deployed by leading industrial firms and are seen as a cost-effective and scalable solution for reducing industrial greenhouse gas emissions.

Industrial emissions account for more than a quarter of global greenhouse gas emissions and are projected to increase without intervention. A significant portion of these emissions is driven by the need for heat in production processes, which is currently met by burning fossil fuels. LDES offers a viable pathway to reduce these emissions by enabling the use of renewable energy for both electric and thermal applications, especially in sectors that are difficult to electrify, such as steel and cement production.

LDES technologies can reduce emissions by up to 65%, which corresponds to an estimated 7.7 billion tons of CO2 emissions reduction potential. They are particularly effective in low-to-medium temperature industrial processes (100°C to 500°C), where they can significantly lower the cost of abatement. In addition, LDES supports industrial operations that are not connected to the grid, such as remote mining sites, by providing reliable, renewable-powered electricity.

Main Viewpoints

• LDES is a critical enabler of industrial decarbonization, especially for sectors with high heat demand that are difficult to electrify.
• LDES is economically attractive for off-grid applications, where it can replace expensive and polluting diesel fuel with renewable energy.
• Policy and market support are vital for accelerating LDES adoption, including subsidies, carbon pricing, and pilot projects.
• Industrial firms are already investing in LDES, recognizing its potential to meet decarbonization goals and reduce operational costs.
• LDES complements other technologies such as electric boilers, heat pumps, and small modular reactors (SMRs) in the industrial decarbonization portfolio.

Key Information

• LDES technologies include electrochemical (flow, metal anode, non-metal chemical storage), thermal (sensible, latent, thermochemical), chemical (green hydrogen, methane, ammonia, methanol), and mechanical (compressed air, liquid air, pumped hydro, gravity-based, liquid CO2) storage methods.
• LDES applications are categorized into three main types:
  • Off-grid electric: Used in remote industrial applications like mining, where reliable renewable energy is needed.
  • "Easy-to-electrify" heat: Sectors where heat can be easily electrified using existing technologies, such as chemicals and food manufacturing.
  • "Hard-to-electrify" heat: Sectors requiring high temperatures (e.g., >1,000°C) or radiative heat, such as steel and cement production.
• Economic analysis shows that LDES can reduce the cost of abatement by over 20% for certain industrial processes, especially when paired with renewable energy.
• Policy mechanisms such as the EU's Carbon Border Adjustment Mechanism and Australia's Safeguard Mechanism are being used to drive decarbonization and LDES adoption.
• Government support is crucial for scaling LDES technologies, as it helps overcome cost barriers and encourages investment in new production processes.

Recommendations

• Governments should implement subsidies, carbon taxes, and pilot projects to incentivize industrial firms to adopt LDES technologies.
• Technology demonstration programs can increase the adoption rate among industrial users by showcasing the viability and benefits of LDES.
• Collaboration between industry and regulators is necessary to develop a supportive policy framework that accelerates the transition to net-zero industrial operations.

Conclusion

LDES is a promising solution for industrial decarbonization, offering a reliable, cost-effective, and scalable means to replace fossil fuel-based energy sources with renewable alternatives. With continued policy and market support, LDES can play a central role in achieving global net-zero goals and ensuring a sustainable, resilient energy future.
