Revel builds and operates public fast-charging stations for electric vehicles, with an initial focus on New York City. The company secured a $60 million loan from NY Green Bank to expand its fast-charging network in NYC. That funding will support nine sites that together will add 267 new fast-charging stalls by 2027; over the next 12 months Revel plans to complete five public sites with about 158 stalls, including a JFK airport station. Revel broke ground at JFK in November and expects that site to open in Q1 2025; its Maspeth, Queens site will include 60 stalls, making it one of the largest public charging stations in the nation. NY Green Bank's loan is its first investment in EV charging infrastructure, which the article frames as a sign that debt lenders are beginning to see charging infrastructure as a returnable investment. Revel is continuing to raise both equity and debt to build additional stations in California and hopes to launch a Bay Area site this year, aiming to serve ride-hail drivers and the emerging electric robotaxi industry. Revel operates high-volume public EV fast-charging Superhubs designed for multiple use cases, including general consumers, Revel’s all-electric rideshare fleet, third-party rideshare operators and light-duty delivery vehicles. Its flagship Superhub is in Bed-Stuy, Brooklyn, and the company plans to open additional sites in US cities in 2023. All new Superhubs will be future-proofed with a large number of stalls and charging speeds of at least 150kW. Revel is led by CEO Frank Reig. The company raised $50M in debt financing led by BlackRock Alternatives through its Climate Infrastructure fund to grow its Superhub network. The investment follows a $126M Series B announced in February that was led by BlackRock. Revel began as a Brooklyn-based operator of shared electric mopeds and has expanded into building public EV fast-charging “Superhubs” and an all-EV ride-hail service. The company launched its first Superhub in Brooklyn last June with 25 charge points and plans to build additional hubs with 10 to 15 universal DC-fast chargers each. Revel says new hubs will be open 24/7 and accessible to any brand of EV. It launched an all-Tesla ride-hail service in Manhattan six months ago with a fleet of 50 Tesla Model Ys and has provided over 93,000 rides to date. Revel is winding down its e-bike subscription unit while continuing its moped service. The company plans to use the new funding to expand its Superhub network across NYC and potentially other major U.S. cities. Revel operates a shared electric-moped service with more than 1,400 mopeds across Washington, D.C., and Brooklyn and Queens in New York. Its core product is motor-vehicle mopeds capped at 30 mph that are intended to ride in the street and require license plates and third-party auto liability insurance. The company provides two helmets (with single-use liners) per ride and requires users be licensed drivers aged 21 or older who pass an initial safe-driving history check. Vehicles have about a 50-mile range, an estimated three-year asset life, and Revel performs battery swaps and routine maintenance every four to six months using full-time employees rather than gig workers. Pricing is $1 to start, $0.25 per minute to ride and $0.10 per minute while parked, and Revel offers a Revel Access program that cuts costs by 40% for eligible riders. The company says the capital will be used to scale its fleet within current cities and expand into new markets, targeting about 10 cities by mid-2020. Revel deploys shared, safety-certified electric mopeds that include insurance and helmets and are registered with the New York Department of Motor Vehicles. After a nine-month pilot that used 68 mopeds, Revel has launched 1,000 new two-rider mopeds across more than 20 neighborhoods in Brooklyn and Queens. Riders must register in the Revel app with a driver’s license and pay a one-time $19 fee for a motor vehicle license check. The company opened a 10,000-square-foot operations facility in Red Hook to support the commercial launch and expanded service area. Revel introduced a new pricing structure — $1 to start plus $0.25 per minute (free first minute), $2 to start for two riders, and $0.10 per minute to pause — and offers a 40% discount for SNAP recipients and NYCHA residents. According to the company, it has raised equity and debt financing to support the rollout.

Travertine commercializes the Travertine Process, which combines salt-splitting electrolysis, caustic direct air capture, and mineralization to convert waste gypsum and atmospheric CO2 into sulfuric acid, green hydrogen, and calcium carbonate (permanent carbon storage). The company is building a demonstration plant at Sabin Metal's main facility outside Rochester/Scottsville, New York, with engineering underway and commissioning expected in mid-2025. The demo is sized to upcycle hundreds of tons per year of gypsum, remove tens of tons of CO2 annually, and supply roughly 50% of Sabin Metal’s annual sulfuric acid needs; future expansion could supply green hydrogen for industrial heat. Travertine says the process can decouple critical element extraction and refining from fossil-derived sulfur and is applicable to lithium, nickel, phosphorus, and cement production. The company is headquartered in Boulder, Colorado and is led by founder and CEO Laura Lammers, PhD. Travertine’s core technology upcycles industrial sulfate waste and CO2 captured directly from the air into sulfuric acid and carbonate advanced cement components that permanently sequester CO2. The produced sulfuric acid is used to extract phosphorus, lithium, nickel, and other critical elements from ores, while eliminating sulfate wastes from conventional extractive processes. The company has demonstrated its process by upcycling sulfate waste from major fertilizer and mining companies in a fully integrated, continuous-flow pilot. Travertine is currently focused on engineering and scale-up for a first commercial demonstration plant. The company plans to use recent funding to expand operations and further its development efforts. Travertine spun out of Laura Lammers’ lab at the University of California, Berkeley in 2022 and is based in Boulder, Colorado. Travertine Technologies develops a novel, cost-effective process to capture and permanently sequester ambient CO2 while producing sulfuric acid. The company aims to enable carbon-negative critical element extraction and fertilizer production through its co-produced sulfuric acid. It is building a pathway to pilot-scale implementation in 2023. The $3M seed investment will be used to scale up the team in Boulder, CO and accelerate that pilot pathway. Travertine was founded by Prof. Laura Lammers and describes its ambition as a gigaton-scale carbon dioxide removal solution. The firm combines CDR with industrial chemical production to address both emissions and raw-material needs.

Evercloak develops a refrigerant-free building dehumidification system based on a proprietary graphene-oxide composite membrane that lets water vapour pass while blocking air. The membrane separates dehumidification from cooling, reducing the energy required to dehumidify and subsequently cool air; the company says this can improve building cooling efficiency by up to 50%. Evercloak is scaling membrane production and building an advanced dehumidification prototype as part of a NYSERDA-funded pilot, with an initial US$350,000 award and a potential US$1.15M extension for full-scale development and demonstration. The company estimates its technology could reduce emissions in the State's building sector by 40%, cut peak energy consumption by 25%, and eliminate two‑to‑five megatonnes of CO2 equivalents per year. Evercloak is actively partnering with HVAC manufacturers to rapidly deploy its systems globally and aims to commercialize the technology through demonstrations in New York City buildings. The company frames its product as a market-first building dehumidification technology to improve indoor comfort while lowering greenhouse-gas emissions. Evercloak develops graphene-composite membranes and a patented manufacturing process for continuous single-layer nanomaterial coatings aimed at membrane-based dehumidification. Its HVAC solution radically reduces the electricity needed to dehumidify air, which the company says can cut air-conditioning energy demands in half. Field trials of two demonstration units in summer 2023 demonstrated performance, and the company is preparing to bring the solution to market. With an oversubscribed $2M seed round, Evercloak plans to scale up membrane manufacturing and strengthen its commercial team. The firm positions its technology as a critical efficiency lever amid rising cooling demand and international pledges to reduce emissions from cooling systems. Based in Waterloo, Ontario, Evercloak says its nano-coating manufacturing approach can also be applied to energy storage, water desalination and other industrial processes.
