Energy systems around the world have started going through rapid and profound transformations. Electric vehicles are breaking into the mainstream, and millions of wind and solar farms are replacing fossil fuel power plants. Both developments create fundamental challenges for the security of electricity supply. Energy storage could resolve these and drive cost-effective deep decarbonization. As a result, the storage industry is projected to grow to hundreds of times its current size in the coming decades.

 

Businesses, policymakers and academics need to assess the economic case for energy storage and the future roles it will play. This is complicated by rapidly falling investment costs, the wide range of technologies, and the vast array of use cases for energy storage.

 

Oliver Schmidt and Iain Staffell introduce an innovative, comprehensive toolkit required for assessing how the benefits of energy storage stack up against its costs. They give sharp insights on future prices, lifetime costs, technology competitiveness, profitability, and market size based on this toolkit. These are complemented by clear and authoritative explanations of the underlying datasets and methods. Worked examples and an easy-to-access online tool further empower readers to conduct their own assessments with custom data. Various frequently asked questions provide real-world context and bust some of the most prevalent myths about energy storage.

 

This book is a must-have for both decision-makers who require key insights into the energy storage business and practitioners who want to perform their own analyses on the current and future cost and value of energy storage.

The Storage.ninja enables you to determine the levelized cost of storage (LCOS) and annuitized capacity cost (ACC) for any technology in any application. You can also choose from pre-defined technologies and applications. 

The ninja uses a peer-reviewed model to calculate LCOS and ACC, but let's you decide on the input parameters. The respective publication is here:

Schmidt, O., Melchior, S., Hawkes, A., & Staffell, I. (2019). Projecting the Future Levelized Cost of Electricity Storage Technologies. Joule, 3, 1–20. 

Database on price reductions

This dataset provides data on cumulative deployed capacity and product price (i.e., investment cost) for electrical energy storage technologies.

 

It allows to construct experience curves (or cost-reduction curves), which can be used to:
 

  • project future investment cost ranges for storage technologies

 

  • determine investment requirements in technology deployment to achieve cost targets

 

  • analyse economic competitivenss of storage technologies in distinct applications

Energy storage maps and databases

There is a range of useful open access energy storage maps and databases! In addition to location, they often provide details on technology, energy and power capacity and use case of specific energy storage projects around the world (sometimes even financial details). 

 

Below is a compilation of theses maps and databases for stationary storage systems (utility-scale, residential and C&I) and for electricity storage in transport applications (e.g., marine).

RE_Ninja.png

Renewables.ninja allows you to run simulations of the hourly power output from wind and solar power plants located anywhere in the world. This tool makes scientific-quality weather and energy data available to a wider community.

The ninja works by taking weather data from global reanalysis models and satellite observations:

The Renewables.ninja is a collaboration between Stefan Pfenninger and Iain Staffell, who both research the effects of integrating renewable technologies into our energy systems.
