Exploring how batteries can inadvertently increase emissions instead of reducing them, the podcast highlights the urgent need for economic incentives to support grid decarbonization. Insights on unlocking revenue streams, addressing battery deployment factors, and promoting grid decarbonization efforts through carbon avoidance offsets are also discussed. The episode concludes with a focus on personal productivity, influential books, and the importance of being climate positive.
Energy storage market is rapidly growing, but new batteries often increase emissions, not reduce them.
Efforts by Energy Storage Solutions Consortium aim to align economic incentives for accelerating grid decarbonization.

Inadvertently Increasing Emissions from Batteries
Despite assumptions that batteries would naturally reduce emissions, it was found that the majority of batteries actually increased emissions. The energy storage market is rapidly growing, but the storage added to the grid often increases emissions rather than reducing them. Efforts are being made by the Energy Storage Solutions Consortium to align economic incentives in the storage market with accelerating grid decarbonization.
Battery Functions for the Grid
Batteries provide various services to the grid, including energy arbitrage, ancillary services, and capacity markets. While energy arbitrage is a common revenue source for batteries, ancillary services like frequency regulation and reserve products are crucial for grid operation. Capacity markets also offer revenue opportunities. However, there is a lack of differentiation in storage markets to value clean storage revenues.
The Need for Carbon Differentiation in Storage Markets
Unlike renewable energy markets, storage markets lack a mechanism to differentiate clean storage revenues from less clean ones. The concept of Renewable Energy Credits (RECs) has accelerated the development of renewable assets. To incentivize cleaner operation of batteries, a carbon offset mechanism is being pursued to attribute value to the decarbonization potential of energy storage.
Challenges in Determining Emissions Reduction from Batteries
Recent studies have revealed that many batteries inadvertently increase emissions due to various factors. Factors influencing emissions reduction by batteries include ancillary market participation, correlation between emissions and prices, and location-specific carbon avoidance opportunities. Efforts are being made to develop a system to accurately measure and attribute emissions reductions resulting from battery operations.
As the energy density of batteries continues to increase even as costs keep declining, the stationary energy storage market is booming, with investment growing by over 7x over the last few years – from $5 billion in 2020 to over $35 billion in 2023 – and with battery installations tripling just last year alone.
While an influx of storage is certainly needed to integrate the vast amount of renewables we need to fully decarbonize the grid, the storage we are adding to the grid is not always or even usually reducing overall carbon emissions. In fact, too often new batteries are resulting in positive net new emissions – an outcome almost no one wants.
In this episode, Chad Reed chats with Jacob Mansfield and Emma Konet of Tierra Climate and Adam Reeve of REsurety to learn more about the efforts of the Energy Storage Solutions Consortium (ESSC), which seeks to align the economic incentives of the storage market with truly accelerating grid decarbonization.
