What is the Project?
Cheesecake Energy is developing the world’s greenest energy storage technology, lowering the cost of medium to long-duration energy storage, and turning renewable energy sources like wind and solar into reliable, on-demand power. The breakthrough system, eTanker, uses thermal energy storage and compressed air to achieve costs that are 30-40% lower than that of the cheapest batteries currently available. This innovation is made possible by repurposing long-lasting, proven industrial components from existing automotive, oil and gas equipment supply chains… It’s a remarkable project designed to transform renewable energy storage into a cost-effective and environmentally friendly solution.
Main Benefit
- 25+ year lifetime
- No hazardous chemicals
- Environmentally friendly & fully recyclable
- Up to 4x charging capability from the same grid connection
- Lower infrastructure costs
With these advantages, the system not only cuts costs significantly but also makes electric fleets possible much sooner. The results are impressive—projects become more bankable as they unlock additional revenue streams through grid services. This means that both operational efficiency and environmental stewardship are prioritized simultaneously.
Energy Storage Innovation
The eTanker system works by using electricity to compress air and by storing both the high grade heat and high pressure air until the stored energy is needed again. When the electricity is required, the air is reheated and expanded to drive a motor which converts the stored energy back to electricity. Essentially, the system leverages compressed air and thermal storage to achieve costs 30-40% lower than lithium-ion batteries—a significant competitive advantage in today’s market. The technology is designed to be sized, transported, and installed quickly and flexibly, making it an ideal option for energy storage needs ranging from large scales down to more localized applications.
Renewable Integration in Detail
eTanker plays a crucial role in balancing generation and load while integrating intermittent renewable sources such as wind and solar. The system offers the opportunity to earn additional revenue through grid services, which can further support its cost-effective performance. With its ability to provide on-demand electricity, the technology reduces reliance on fossil fuels and decreases environmental impact. This is particularly important for communities that are working towards 100% renewable penetration—powering electricity grids and mini-grids right across the globe. The project’s seamless integration with renewable assets fosters a more resilient and sustainable energy infrastructure… It’s all about making renewables more dependable and accessible.
Industrial and Grid Advantages
eTanker not only offers environmental benefits but also delivers clear advantages for heavy industry companies. By enabling deeper integration of renewable energies, the system helps reduce dependence on fossil fuels in industrial operations. Moreover, eTanker can unlock new sites and maximize returns from exports, providing customers with more predictable revenues. This increased reliability makes projects more bankable and attractive to investors. The technology is perfectly suited for charging fleets of electric vehicles, supplying residential neighborhoods or factories, and aiding renewable generators in managing intermittency. Such versatility ensures that the benefits span across various sectors—industrial, residential, and utility. It is an all-around game changer in the way energy storage systems are thought about today.
Operational Efficiency and Flexibility
This project develops technology that is not only efficient but also remarkably flexible. As an OEM supplier of hardware solutions to energy storage project developers, Cheesecake Energy Ltd aims to provide the cheapest and greenest energy storage option available. The system is designed for rapid deployment and has the added advantage of being easily transported and installed in a variety of locations. Because of its scalable nature, it can be optimized for charging entire fleets, powering neighborhoods, or even supporting the grid during peak demand times. The operational efficiency of eTanker means that with the same grid connection, there is an additional charging capability up to four times greater than what is usually expected… It brings a new level of adaptability to modern energy challenges.
