H2G Green Limited's GEIH and A*STAR Sign Agreement to Commercialise Biomass-to-Hard Carbon Technology for Sodium-Ion Batteries
SINGAPORE, July 30, 2025 /PRNewswire/ -- H2G Green Limited (SGX:5AI) ("H2G" or the "Company", together with its subsidiaries, collectively the "Group"), a leader in sustainable energy solutions, and its subsidiary Green Energy Investment Holding Private Limited ("GEIH") today announced a licence agreement with Singapore's Agency for Science, Technology and Research ("A*STAR").
GEIH is an innovator in sustainable hydrogen with proprietary technologies that repurposes and transforms waste biomass into green hydrogen, as well as biochar and other high-value, sustainable materials. GEIH will commercialise a proprietary treatment process by A*STAR Institute of Materials Research and Engineering (A*STAR IMRE) to purify biochar, a by-product, into high-value hard carbon material for market use. Hard carbon materials are primarily used as anodes for batteries such as sodium-ion and lithium-ion batteries, due to their unique properties. They are also found in applications for water and air purifications as well as conductive additive in paints and coatings.
Following execution of the licence agreement, GEIH and A*STAR will begin the next phase of scaling up to accelerate the commercialisation pathway of the biochar purification process, focusing on producing hard carbon as anodes for use in sodium-ion batteries.
Mr. Sydney Kwan, CEO of GEIH, remarked: "We are deeply grateful to A*STAR for their ongoing collaboration and support. Our joint efforts are transforming the nation into a hub for sustainable technologies and green energy."
An earlier exploratory phase found that the hard carbon GEIH produces tends to be superior to existing commercial materials due to a high graphite content, which makes the material favourable for anodes in sodium-ion batteries. These have possible applications for grid-scale energy storage, electric vehicles, and consumer electronics. The abundance of sodium makes sodium-ion batteries a more sustainable alternative to lithium-ion batteries.
GEIH's technologies make it especially suited to this endeavour. The Company's proprietary high-temperature thermochemical process turns any type of biomass without silica into hydrogen, biochar, bio-oil (for sustainable aviation fuel), and wood vinegar. The entire process incorporates circularity of materials as a guiding principle, and production of biochar results from incorporating carbon sequestration. The output materials power sectors as diverse as data centres, wafer fabrication, construction, agriculture, food manufacturing, laundry services, and central kitchens.
Mr. Pek Hak Bin, CEO of H2G, added: "Hydrogen is the energy of the future and a core part of Singapore's low-carbon energy strategy. H2G is expanding possibilities for Singapore and beyond by pioneering a novel hydrogen production process that is cost-effective, less carbon intensive than electrolysis, and repurposes waste into sustainable materials. These power sustainable industries, as our hard carbon anode materials for sodium-ion batteries will empower a broader range of industries to reduce their environmental impact. In this way, H2G creates win-win-win sustainability solutions to multiple problems across industries."

Some MLB teams make trades. This one dealt nearly half its roster
A month and a half into this season, the hottest team in Major League Baseball played in Minnesota. When the standings closed on May 17, the Twins had won 13 consecutive games to sit second in their division. It was the franchise's longest winning streak in 34 years, and the longest in all of MLB since 2022. Minnesota had one of baseball's best staff of relief pitchers and an All-Star outfielder in Byron Buxton. Suddenly, a spring training declaration by the team's top baseball executive, Derek Falvey, that reaching the World Series 'has to be the mission from Day One,' sounded more like a possibility. By this week's trade deadline, that mission had changed dramatically. No longer ascending in the standings, the Twins had moved from a buyer looking to bolster its lineup ahead of a playoff run into a seller trying to extract some value from a lost season — the kind of shift in thinking that happens to numerous teams across all professional sports. Yet the scope of the Twins sell-off Thursday, in the final hours before the deadline, was anything but typical. Many teams out of playoff contention sell off key parts; the Twins, however, took it to an extreme. Over nine trades, they dealt away 11 players from a 26-man roster. When Falvey sent a signed message to fans late Thursday, he wrote that 'this wasn't about patchwork or small adjustments." That was an understatement. 'We had been hovering around or under .500 for a period of time and just couldn't quite get things going in the right direction, and we've got to find a new way to do it,' Falvey told reporters. Falvey framed the roster reset as a baseball decision for the future of a team that had gone from six games above .500 on May 17 to six games under. But along with bringing back a collection of prospects, the trade also accomplished slashing its payroll, and making it less expensive to operate. The trade of the highest-paid Twin, shortstop Carlos Correa, was effectively to ensure that another team, Houston, would foot the bill for more than $70 million of his remaining salary. The Twins have historically never been among the top-spending teams, and their decline since May had only further disincentivized adding costs to a team whose ownership has been publicly looking to get out of the baseball business since late last year, when the Pohlad family — which has owned the franchise since 1984 — announced it was looking sell the team. 'The sale process continues to be an ongoing reality for our organization and something that we will work through at the right time,' Falvey said. The intention to sale was announced at a time when labor peace between players and the league, and the attractiveness of owning a franchise in a smaller market, have come under question. Six teams last season had a payroll of $102 million or less, according to Spotrac, less than the amount the Los Angeles Dodgers reportedly paid in taxes alone. The average MLB team valuation at the season's start was $2.62 billion, per CNBC. Minnesota's $1.6 billion valuation ranked 22nd out of 30 teams. The few remaining holdovers include pitcher Joe Ryan and Buxton, who only two weeks earlier had noted the security provided by his no-trade clause. "I'm a Minnesota Twin for the rest of my life," Buxton said at the All-Star game. "So, that's the best feeling in the world." The Twins woke up to a different feeling Friday. To fill out their roster for their first game after the deadline, the Twins were forced to call up eight players from the minor leagues. Gone are five relievers from a bullpen that had shined during the team's winning streak, including top closer Jhoan Duran. Players on longer contracts, such as Correa, and others expiring at the end of the season were dealt with equal measure. On Reddit, one user noted that the roster upheaval had turned the Twins' official Instagram account into a series of graphics announcing either a 'trade alert' or a 'thank you' to a departed player. The extreme teardown took place less than two years after Minnesota won its division and made the postseason for the first time in three years. 'I had some conversations with the front office in Minnesota and we were not moving in the direction that I thought we were after [making] the playoffs [in 2023], and they agreed with me that it was time to move me,' Correa told And 10 others, too.

Evercore's Purchase of Robey Warshaw May Birth Trans-Atlantic M&A Titan
It's a deal designed to launch a thousand others. On Wednesday, Evercore announced that it's acquiring London-based investment bank Robey Warshaw, a similarly modest boutique firm with an outsized presence in the M&A space, for nearly $200 million. The only question: Who's soaking up the advisory fees? READ ALSO: Big Tech Pulls Off a Very Big Earnings Week and Barnburner Figma IPO Offers Good Omen as Klarna Reconsiders Debut International Man of M&A History Founded by former US Deputy Treasury Secretary Roger Altman in 1995, Evercore has grown into something of a full-fledged rival of major Wall Street banks in the M&A space. Last year, the firm finished sixth in PriceWaterhouseCoopers' US advisory fee-ranking report after advising on 151 deals worth a total of $291 billion. In its second-quarter earnings report this year, Evercore touted its advisory business scoring record first-half revenues after handling four of the 10 largest transactions so far in 2025, including Dick's Sporting Goods' $2.5 billion acquisition of Foot Locker and Cox Communications' merger with Charter Communications. Now, Evercore is applying its M&A expertise to its own business, with the Robey Warshaw acquisition marking its largest deal since buying research and brokerage firm ISI Group over a decade ago. Why? Strategic expansion, of course, and perhaps because Evercore sees something of itself in Robey Warshaw: Despite employing just 18 people in total, Robey Warshaw has made itself a mainstay in the UK (which remains the second-largest market for investment banking fees behind the US), advising on some of the biggest UK deals in recent memory, including SoftBank's £24 billion acquisition of chipmaker Arm and AB InBev's $79 billion purchase of SABMiller. Much of the firm's success has been credited to its leadership team, including co-founders Simon Warshaw and Simon Robey, with the latter receiving nearly 50% of the firm's profits each year, per the Financial Times. The deal locks in each of Robey Warshaw's five partners, including the 65-year-old Robey, for at least six years. European Vacation: The deal will help bolster Evercore's presence in Europe, where it placed 13th by deal volume in PwC's advisory rankings last year. It's the bank's first major acquisition on the continent since its roughly £86 million takeover of boutique investment firm Lexicon in 2011, though it has recently pulled off some high-profile talent poaching in France, including the hiring earlier this year of former top Citigroup dealmaker Luigi de Vecchi to serve as Evercore's European chair.
