GM pauses $55M hydrogen plant with Piston Automotive in Detroit
General Motors has suspended a $55 million project with Piston Automotive to manufacture hydrogen fuel cells at a plant on the old State Fairgrounds site in Detroit.
The automaker paused work at the plant and will determine whether to move forward with it in the coming weeks, a person familiar with the matter told Automotive News affiliate Crain's Detroit Business.
Piston, which counts GM among its top customers, entered into an agreement with the automaker last September to lease and operate a 292,550-square-foot plant, where it expected to create 144 jobs. It is the first standalone plant dedicated to fuel cell production for GM.
GM spokesman Kevin Kelly declined to provide details about the status of the project other than to say it has not been cancelled.

The reason for GM pausing the project is not clear, but it comes at a challenging time for the automotive industry. Carmakers and suppliers are navigating the impact of tariffs under the Trump administration and at the same time grappling with how to place their bets on future propulsion systems as regulations and consumer demand shift. GM executives said earlier this month they anticipate a $5 billion hit this year from tariffs.
The hydrogen holdup is the latest GM project in Michigan facing uncertainty. The automaker is reassessing product plans for the long-delayed Orion Assembly Plant 35 miles North of Detroit in Oakland County and the future of the Renaissance Center in downtown Detroit remains unclear as GM prepares to move its headquarters to Dan Gilbert's Hudson's Detroit development.
GM has plenty of company when it comes to indecision about new propulsion investments. Michigan saw a wave of hydrogen and battery plant announcements a couple of years ago, but many of them have either been stalled, shrunk or scrapped. Economic development officials say that most of the projects will pay off, but it will just take longer than expected.
GM was among several manufacturers to be awarded a chunk of $750 million by the U.S. Energy Department a year ago under then-President Joe Biden to boost hydrogen fuel cell production. Some of that funding, which GM has yet to receive and is in question under President Donald Trump, was committed to pay for tooling at the Detroit plant.
The plant was intended for low-volume production, but GM declined to say how it would use the fuel cells. It is likely they would be used in nonautomotive applications before going into trucks. In addition to the Piston supply deal, GM has a joint venture with Honda producing fuel cell systems at a 70,000-square-foot plant in Brownstown Township, 20 miles South of Detroit. Unlike the Piston plant, the one in Brownstown Township produces components in addition to fuel cells.
Piston was awarded $1.5 million performance-based grant from the state in January to support the hydrogen project. Michigan Economic Development Corp. spokesman Otie McKinley said none of that money has been disbursed.
Piston, owned by former Detroit Pistons guard Vinnie Johnson, a Crain's 2024 Newsmaker of the Year, has a large chunk of business tied to GM projects in a holding pattern. The supplier was tapped by GM to operate a $278 million, 960-job plant at the former Palace of Auburn Hills site to supply Orion Assembly.
At the old State Fairgrounds site, Piston was tasked with making the investment and creating the jobs under a nine-year contract, though the exact financial structure of the deal is unclear, as is the amount of money that has been invested so far.
The building occupied by the hydrogen program is part of a massive speculative redevelopment project completed by Sterling Group and Hillwood. Greg Scovitch, vice president of development for Hillwood, told Crain's this month he was unaware of any changes with the user's plans.Have an opinion about this story?

Success or strike out? A's a boon to some local business, others left waiting for major league momentum
Some West Sacramento businesses are booming, others not so much since A's arrival Some West Sacramento businesses are booming, others not so much since A's arrival Some West Sacramento businesses are booming, others not so much since A's arrival WEST SACRAMENTO – Before the Athletics' three-year relocation to Sutter Health Park, West Sacramento small businesses were pitching big ideas to cash in on the Major League momentum from the first day the move was announced. Now, two months into the season, some call it a success. Some call it a strikeout, still waiting on the business boom they were hoping for. How helpful the team has been for the business depends on who you ask. Drake's: The Barn, basically next-door neighbors with the A's, is hitting it out of the park. "This is very much our A's pre-game pop," said Bia Hoskins, general manager of Drake's, as she gestured to a packed house on Friday night, an hour before first pitch. Things have been busy at Drake's, where big league ball has brought big league business. "We've definitely seen an uptick in that walk-in traffic leading up to A's games. On a home week, we definitely plan ahead," said Hoskins. "We've benefited for sure from the team being here, people wanting a quick bite and drink before they head to the game. It's been really impactful for us and we've really enjoyed it." But other small businesses just blocks from the ballpark are still waiting for their major league moment. "We see a little uptick in business. But nothing, nothing like we anticipated," said Jeff "Fro" Davis, owner of Treehouse Cafe. Treehouse Cafe changed their hours and offerings to welcome an A's crowd. It hasn't materialized like Davis had hoped. "We had a full outside bar, live bands. But it didn't come to fruition like we thought. Right now, on weeknights, I have one cook and a bartender. And that's all we need," Davis said. Davis said he had to scale back the extra staffing he hired, but is still basing his hours around each A's home game. Live music now is limited to the weekend games. "People are barely walking down the street in front of us here. We are not seeing the impact like we thought we would," Davis said. "It depends on the brand. When the Yankees were in town, we were packed. I'm looking forward to the Giants coming to town Fourth of July weekend." About 15 minutes from the stadium in Southport, West Sac Sports Bar and Grill invested in renovations, trying to become a home base for A's fans away from the stadium. Unfortunately, former owner Shawn Mason says it didn't pay off. Mason tells CBS13 he sold his bar to a new owner last week after 11 years in business. He said it's because that expected business boom never came and an A's losing record hasn't helped. What's been a success for some has been a strikeout for others. "But, it is what it is, and we are just lucky to be a part of the scene," Davis said. So far this season, A's attendance has been good, not great. The average for ticketed fans is just over 10,000. But the A's have only put up four sellout crowds, the home opener versus the Chicago Cubs and the entire three-game series versus the New York Yankees. The lowest attended game of the season to date was on Tuesday, June 3, versus the Minnesota Twins, with 8,487 tickets sold.

Analysts unveil bold forecast for Alphabet stock despite ChatGPT threat
Analysts unveil bold forecast for Alphabet stock despite ChatGPT threat originally appeared on TheStreet. You typed in a question and clicked a few links, and Google could get paid if you landed on an ad. For years, that simple cycle helped turn Google into a trillion-dollar titan. But now, that model is under threat. 💵💰💰💵 AI-powered chatbots like OpenAI's ChatGPT are rapidly changing how people find answers. Instead of browsing through links, users are getting direct summaries on AI. These 'zero-click' searches quietly erode the economics that built the modern internet. The number of users is growing fast. OpenAI CEO Sam Altman said in April that ChatGPT already has 'something like 10% of the world" in terms of users, pegging the number closer to 800 million, Forbes reported. Even Google seems to know it. It's giving AI answers, called AI Overviews, right at the top of the page. "What's changing is not that fewer people are searching the that more and more the answers to Google are being answered right on Google's page. That AI box at the top of Google is now absorbing that content that would have gone to the original content creators," Cloudflare CEO Matthew Prince said in a CNBC interview. Alphabet () , Google's parent company, isn't showing any cracks just yet. In April, the company posted first-quarter revenue of $90.23 billion, topping Wall Street expectations. Earnings per share came in at $2.81, far above the forecasted $ the backbone of Google's business, brought in $66.89 billion, accounting for nearly three-quarters of total revenue. Its 'Search and other' segment rose almost 10% year over year, hitting $50.7 billion. Meanwhile, Google's own AI tools are starting to show traction. AI Overviews now has 1.5 billion users per month, up from 1 billion in October, the company said. So far, the numbers suggest that AI isn't cannibalizing Google's business yet. Bank of America remains bullish on Alphabet stock. The firm reiterated a buy rating and a price target of $200, which implies a potential 15% upside from current levels, according to a recent research report. The firm said in May, Google's global average daily web visits held steady at 2.7 billion, unchanged from the previous month and down 2% from a year earlier. ChatGPT, meanwhile, saw a 3% month-over-month increase to 182 million, marking a 105% jump the U.S., Google traffic slipped 2% year-over-year to 524 million daily visits, while ChatGPT surged 112% over the same period to 26 million. Although Google has highlighted the growing reach of its AI Overviews, analysts are uncertain whether it's translating into more traffic. 'So far, we are not seeing a lift in Google traffic from AI Overviews expansion, though we think the search experience is much improved,' the analysts wrote. The competition is real. Google's global search share also edged down in May, falling 8 basis points month-over-month and 123 basis points year-over-year to 89.6%, according to Statcounter. Still, Bank of America analysts remain optimistic on Alphabet stock. "While ChatGPT's traffic continues to grow rapidly, we think Google remains well-positioned given its scale, multi-product reach, data assets, and robust monetization infrastructure," the analysts said. "AI can expand overall search monetization by better understanding the intent behind complex and long-tail queries that were previously hard to monetize," they added. Morningstar's Malik Ahmed Khan echoed that sentiment, saying Alphabet's diverse revenue streams and global exposure should cushion any hits, even as regulatory and AI risks mount, according to a May research report. Alphabet stock closed at $174.92 on June 6.
