February 20, 2025: Pulse Clean Energy launched its open-source UK BESS Carbon Emissions Calculator on February 18 and said it was to improve understanding of the environmental benefits of battery storage in the energy sector.

Pulse claimed the tool was an industry-led first, released in collaboration with LCP Delta and the UK National Wealth Fund — a government-backed bank set up to help crowd-finance infrastructure and other projects.

The tool tracks and certifies the impact of batteries as they reduce carbon emissions by storing excess energy from renewable sources and feeding it back into the grid at times of peak demand, reducing reliance on fossil fuels.

Pulse said the tool provides a standardized method of measuring that impact, allowing BESS owners, investors, and policymakers to have a reliable, transparent flow data with which to validate sustainability claims and make informed improvements.

While historically, most operators have calculated BESS emissions impacts using average emissions figures from the National Energy System Operator, the Pulse tool uses real-time data from Elexon, the UK’s electricity market operator, to calculate the marginal emissions factor for each half-hour period of interest.

Pulse is now encouraging all BESS investors, lenders and asset owners across the country to use the free tool, which can also be used with renewable energy systems such as wind and solar.
