Cummins Buys a Climate Seat After Accelera’s Write-Downs

Cummins Inc. joined Emerald as a Limited Partner on Aug. 28, 2026, and declined to say how much it committed.

The Columbus, Indiana, company is paying a Zurich climate fund for startup scouting after Accelera’s hydrogen charges, even as diesel generators for data centers set the quarter’s sales records.

Cummins Joins a Club Caterpillar Already Sat In

Emerald Technology Ventures, founded in 2000, manages and advises assets of over €1.3 billion from offices in Zurich, Toronto and Singapore. It runs four funds and six third-party mandates. Cummins, listed as CMI, employs about 67,400 people and earned $2.8 billion on $33.7 billion of sales in 2025.

A limited partner puts money into a fund and stays out of day-to-day management. Cummins framed the seat as another channel for technologies in power, mobility, energy systems, digital tools and industrial decarbonization, not as a new in-house venture arm.

Emerald already counts Microsoft, Temasek, ABB, Caterpillar, Nestlé, Mitsubishi Heavy Industries and Chevron as investors. Its fund base includes more than 50 Fortune 500 corporations. Cummins is walking into a crowded industrial room, not a private scouting deal.

We are proud to welcome Cummins to the Emerald LP community. Cummins brings a unique combination of industrial scale, technology leadership, engineering excellence, and long-term commitment to sustainability. Together, we aim to turn bold ideas into real-world solutions by connecting Cummins with the most relevant innovators in our global ecosystem.

Christoph Frei, Partner and Head of Energy, Emerald Technology Ventures

Frei’s welcome is the standard LP pitch. The harder read is that Caterpillar, a rival in engines and off-highway power, has been on Emerald’s investor list for years. Deal flow in this model is shared, then filtered through each corporate’s own plants.

Accelera’s Hydrogen Bill Came Due First

Accelera is Cummins’ zero-emissions segment for batteries and electric powertrains. In 2025 it posted $460 million of sales and a $438 million loss. That is a rounding error next to the rest of the company, and it was the unit that absorbed the hydrogen hangover.

Cummins’ annual report says weak demand and thinner government incentives led it to $458 million of Accelera charges in 2025, $415 million of them non-cash, and to stop new commercial activity in electrolyzers while it finishes old orders. In the first quarter of 2026 it sold its low-pressure fuel cell business, made a net payment of $175 million, and booked a $199 million charge. Those are two different hits, not one combined write-off.

ACCELERA’S HYDROGEN RETREAT

1. Third quarter 2025: Records a $210 million goodwill impairment on electrolyzers and writes down inventory, with third-quarter Accelera actions totaling $240 million.
2. Fourth quarter 2025: Adds $218 million of charges after a further strategic review and says it will stop new electrolyzer sales, subject to local consultation, while honoring existing customers.
3. First quarter 2026: Sells the low-pressure fuel cell business, pays a net $175 million, and takes a $199 million charge.
4. June 30, 2026: Accelera posts $145 million of quarterly sales, up 38 percent, and an EBITDA loss of $69 million, narrower than a $100 million loss a year earlier.
5. September 22, 2026: Accelera’s Guadalajara plant in Spain, opened in October 2024 with 500 MW of capacity, ships the last of 20 HyLYZER-1000 units for BP’s 100 MW Lingen project in Germany, due in 2027 and sized for up to 11,000 tonnes of hydrogen a year. The site is being turned toward battery work.

Accelera’s second-quarter sales still rose, and Cummins raised 2026 Accelera guidance to $350 million to $400 million of sales and losses of $260 million to $290 million. First-half Accelera sales were already $246 million, so the back half is built to slow as electrolyzer deliveries finish. The growth is real and the base is still about 1 percent of segment sales.

Data Center Demand Keeps the Engine Shop Busy

Cummins reported $9,457 million in second-quarter sales for the period ended June 30, 2026, up 9 percent from $8,643 million. Net income was $932 million, or $6.73 a diluted share, against $890 million and $6.43 a year earlier.

Power Systems, the generator and high-horsepower business, did the heavy lifting. Segment sales were $2,255 million, up 19 percent, with EBITDA of $552 million, or 24.5 percent of sales. Cummins pointed to backup power for data centers in the United States, China and Asia Pacific. CEO Jennifer Rumsey has said the company is taking diesel backup-power orders well into 2028.

CUMMINS Q2 2026 BY SEGMENT

Intersegment sales of $2,244 million are stripped out of the $9,457 million company total. Accelera’s $145 million is 1 percent of the $11,701 million in combined segment sales. At an analyst day in May 2026, Cummins also said it would put an extra $450 million into high-horsepower engines and gensets to add 20 gigawatts of capacity and reach 55 gigawatts by 2030.

That is the cash engine under the Emerald check. A climate LP is cheap next to a generator backlog that already stretches years, and next to Accelera losses that still run to hundreds of millions a year even after the cuts.

What Cummins Bought With the LP Check

Jeff Wiltrout, vice president of corporate strategy, did not pitch a new product line. He pitched a filter.

Innovation has always been central to Cummins’ ability to help customers succeed through industry transitions. Our relationship with Emerald provides another channel to identify and evaluate technologies that could support our customers’ evolving needs and furthers our growth strategy.

Jeff Wiltrout, VP Corporate Strategy, Cummins Inc.

The Aug. 28 release lists four practical returns, and none of them requires Cummins to build another Accelera-scale P&L.

WHAT THE LP SEAT IS SUPPOSED TO DELIVER

• Startup access: Curated companies in energy systems, electrification, digitalization, mobility and industrial technology.
• Deal flow and briefings: Tailored deal flow, sector deep dives, and priority time with Emerald’s investment teams.
• Sprint pilots: Short programs that match a Cummins problem to a startup and aim for a plant trial, not a white paper.
• Corporate network: Introductions across Emerald’s other industrial limited partners, investors and technology operators.

Cummins said Emerald’s map lines up with software-defined vehicles, advanced powertrains, batteries, firm clean energy, power management, and data-center and grid tools. It also said the tie-up is meant to go past a financial stake, toward pilots and knowledge transfer. That is the tell. After Accelera’s electrolyzer retreat, outside scouting is cheaper than another full-scale build.

WHAT WE KNOW

• The date: Cummins announced the LP seat on Aug. 28, 2026, from Zurich.
• The mechanism: Limited-partner access, Sprints, and shared deal flow, with no new Cummins venture brand attached.
• The overlap: Emerald’s stated sectors match Destination Zero’s remaining bets in batteries, powertrains and grid-adjacent power.

WHAT IS UNCONFIRMED

• The check: Cummins would not disclose the commitment.
• The vehicle: The company did not name which Emerald fund it joined.
• The first pilot: No startup, plant trial or co-investment has been announced under the new seat.

Until those three items land, the LP is an option, not a conversion. A climate label on a generator company will keep drawing that charge, and it will stick if the first Sprint never reaches a test cell in Indiana.

Fifty Corporates Share the Same Deal Flow

Emerald’s model is built for this crowding. Gina Domanig, managing partner, said on the firm’s 25th anniversary in August 2025 that when Emerald launched in 2000, “investing in sustainability was far from mainstream,” and that 25 years later the same idea had become “an imperative for industries worldwide.” The business that grew up around that line is a club of corporates who pay for a common origination machine.

Japanese industrials have been a thick part of that club. Mitsui Kinzoku joined the Industrial Innovation Fund in May 2026 as a 13th Japanese limited partner, in a group that already included DIC, Mitsubishi Heavy Industries and Nabtesco. Festool Group joined the same fund in November 2025. Cummins did not say it entered that vehicle, and that distinction matters. The pattern still holds: large manufacturers rent Emerald’s pipeline instead of staffing a full corporate venture team in Zurich.

Shared origination has a cost. A battery or power-management startup that looks useful to Cummins can look just as useful to Caterpillar, ABB or a Japanese materials group in the same data room. The LP seat buys a look and a chance to run a Sprint. It does not buy exclusivity, and it does not replace the factories that still ship diesel sets into 2028.

Sprints Put Startups on the Factory Floor

Emerald Sprints are the part of the package that can change a Cummins plant, if anyone uses them. A corporate names a problem. Emerald’s sector team pulls startups with a usable technology-readiness level. The two sides meet. The hoped-for output is a pilot proposal, not a memo.

An April 2024 Emerald recap, after ten Sprints, said 60-plus companies had taken part, 170 startups have been shortlisted and introduced, and more than 140 collaboration meetings had followed. Named outcomes included a packaging firm testing coatings, a mining firm running a carbon-capture proof of concept, and an oil-and-gas firm moving toward an investment in a waste-analytics startup. Emerald’s own FAQ puts the corporate time cost at about 20 hours from challenge-setting through one-to-one meetings.

HOW A SPRINT IS SUPPOSED TO RUN

• Challenge: Cummins would have to name a live problem, such as battery integration, grid-tied gensets or alternative-fuel controls.
• Match: Emerald’s energy team, led on this account by Frei, would pull a short list rather than an open call.
• Trial: A plant or a customer site would have to host a proof of concept, which is the step Accelera used to try to own in-house.

For founders in Emerald’s net, Cummins is a customer with scale, a dealer network and a service base. It is also a company that just taught the market it will cut a zero-emissions line when policy and demand slip. That history will sit in every first meeting. The useful test is not whether Cummins can write an LP check. It is whether a Sprint can get a hardware team onto a Cummins stand in months, without another $458 million lesson.

Outside Scouts for a Smaller Accelera

Destination Zero still sits on Cummins’ site as the long path to lower-carbon products. The near-term mix is clearer in the filings than in the slogan. Accelera is being paced toward batteries and electric powertrains. Electrolyzer sales to new customers have stopped. Fuel cells were sold. Power Systems is adding genset capacity. The Emerald seat is how the company keeps a window on the rest without putting it back on the segment P&L.

Cummins still has not said which fund it joined or how large the check is. Until a named startup walks into a Cummins plant under this LP, the climate seat is an option on someone else’s deal flow, paid for by the generator shop that had the better quarter.
