As electricity demand rises and renewable energy grows in the U.S., battery storage is key. Waymo has launched a battery repurposing program to give retired electric vehicle (EV) batteries a new purpose in the power sector.

Waymo is working with B2U Storage Solutions to turn used batteries from its all-electric fleet into large-scale energy storage systems. Instead of recycling these batteries after use, Waymo will repurpose them to store electricity and support local power grids.

This program reflects a commitment to the circular economy, keeping products useful before recycling.

Adam Lenz, Head of Sustainability & Environment at Waymo, said:

“Our shared fleet of EVs provide a massive opportunity to support the growth of clean energy on the electricity grid while expanding the circular economy. Through this partnership, we can repurpose our batteries for local grid storage and ensure our batteries continue to provide economic and environmental value to the community long after they’ve retired from the road.”

Turning Old EV Batteries Into Energy Assets

EV batteries often retain significant storage capacity after their driving days. While their performance may drop for vehicles, many can still serve well in energy storage projects.

The press release says that retired Waymo batteries will join grid-connected energy storage systems through this partnership. These systems will store electricity from renewable sources like solar and wind.

During peak renewable generation, especially when solar production is high, the batteries will absorb excess electricity. Later, when demand increases in the evening, this stored energy can flow back into the grid.

This process helps balance electricity supply and demand, making renewable energy more reliable.

B2U specializes in second-life battery storage technology. They will manage the batteries during their second use and ensure proper recycling when they reach the end of their life.

This collaboration creates a complete lifecycle pathway for EV batteries—from vehicle use to energy storage and finally recycling.

Supporting Growing Demand for Battery Storage

This initiative comes at a time of rapid growth in renewable energy and battery storage in the U.S.

  • According to the U.S. Energy Information Administration (EIA), developers plan to add 86 gigawatts (GW) of new utility-scale electricity generation capacity by 2026. If completed, it would be a record increase.

Solar energy will account for over half of these additions, with battery storage the second-largest category. Wind energy also plays a significant role in this growth.

In 2025, the U.S. power sector added 53 GW of new capacity, the highest since 2002. Meanwhile, battery storage installations keep increasing.

  • They also expect to add about 24 GW of utility-scale battery storage in 2026, surpassing the previous record of 15 GW installed in 2025. Over the last five years, more than 40 GW of battery storage capacity has been added to the grid.

Texas, California, and Arizona are expected to account for around 80% of the planned battery storage in 2026.

The Grid Advantage of Reusing EV Batteries

Repurposing EV batteries offers crucial benefits for power systems and communities.

First, it extends the useful life of battery materials. Making lithium-ion batteries requires a lot of critical minerals and energy. Second-use batteries maximize the value of those materials.

Second, second-life batteries can lower energy storage costs. Since the batteries have already served in transportation, utilities can access storage capacity at lower costs than buying new systems.

Third, repurposing helps reduce electronic waste. Companies can keep batteries in use for several more years, easing pressure on waste management.

  • Most importantly, battery storage boosts grid reliability. Renewable sources like solar and wind don’t produce electricity constantly. Energy storage systems fill this gap by storing power when production is high and delivering it when demand rises.

As renewable energy grows, these storage systems will be vital for stable electricity networks.

Freeman Hall, CEO of B2U Storage Solutions, said:

“This agreement marks a significant milestone in B2U’s mission to provide integrated repurposing services to the automotive industry. By extending the use of these batteries as grid storage, we are monetizing the full potential of EV batteries, now providing crucial stability to the power grid as energy demand continues to grow.”

First Deployments Planned for Texas and California

The first battery storage projects in the Waymo-B2U partnership will focus on Texas and California. Waymo already provides public autonomous ride-hailing services in these states.

Both states lead in renewable energy deployment. California increasingly relies on clean electricity and often has periods where renewable generation exceeds demand. Texas continues to lead the nation in new solar installations.

Waymo plans to repurpose old EV batteries into stationary storage systems. This will help manage renewable energy growth and improve local electricity infrastructure.

The company believes this initiative could deploy hundreds of megawatts of storage capacity in these regions. As autonomous EVs retire, their batteries could continue to provide value long after leaving the road.

This partnership shows how transportation electrification and clean energy can work together. Instead of viewing used EV batteries as waste, Waymo and B2U are transforming them into valuable energy assets. These assets support grid reliability, renewable energy integration, and a sustainable circular economy.

Waymo’s Broader Sustainability Efforts

The battery repurposing program is part of Waymo’s larger sustainability strategy. The company operates one of the largest fleets of fully autonomous electric vehicles, providing over 500,000 paid EV trips each week. These trips help cut emissions by replacing conventional vehicles with electric ones.

  • Waymo estimates that every 500,000 weekly trips prevent about 530 tons of carbon dioxide emissions.

It also measures emissions avoided through its autonomous electric service. This framework evaluates the environmental benefits of electric, autonomous, and shared mobility solutions.

Additionally, the company reports its greenhouse gas emissions through parent company Alphabet as part of broader environmental efforts.

The Strategic Case for Nature-Based Carbon Investments

Published

on

Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.

1. Define the sourcing problem before choosing a project

Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.

This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.

CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.

2. Develop nature-based carbon investments around the actual supply chain

The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?

Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.

Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.

The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.

3. Compare the proposal with other ways to protect supply

WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.

The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.

The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.

The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.

4. Establish what the carbon outcome could count toward

Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?

Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.

SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.

For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.

Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.

5. Build a financial case that survives weaker assumptions

Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.

Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.

Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.

A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.

6. Fund a pilot with a clear expansion decision

Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.

Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.

Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.

This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.

EU carbon credit claims after 27 September 2026

Published

on

EU carbon credit claims changed on 27 September 2026, the day the Directive (EU) 2024/825 began to apply across the European Union. The change is narrow. It changes how a company can talk about the credits it buys. A product can no longer be called neutral on the strength of compensation alone; however, every specific, evidenced statement about what a company measured, reduced, and funded stays fully available.
