On Galvanize’s latest fund strategy and more of the week’s big money moves.

This week brings encouraging news for companies on land and offshore, from the Netherlands to East Africa. First up — and in spite of a federal administration that appears to be actively hostile toward residential and commercial electrification and energy efficiency measures — California gubernatorial candidate Tom Steyer’s investment firm Galvanize just closed a fund devoted to decarbonizing real estate. Elsewhere, we have a Dutch startup pursuing a novel approach to clean heat production, a former Tesla exec rolling out electric motorbikes in East Africa, and an offshore wind developer plans to pair its floating platform with underwater data centers.
With electricity costs on the rise and war in Iran pushing energy prices further upward, energy efficiency measures are looking more prudent — and more profitable — than ever. Amidst this backdrop, the asset manager and venture firm Galvanize announced the close of its first real estate fund, bringing in $370 million as the firm looks to make commercial buildings cleaner and better able to weather price fluctuations in global energy markets.
Galvanize, co-founded by the billionaire Tom Steyer, is already doling out this money, investing in 15 buildings across 11 cities so far. The firm targets real estate in cities where demand is outpacing supply, performing decarbonization upgrades such as installing on-site solar generation and undertaking energy efficiency retrofits such as improved insulation and weatherproof windows.
Galvanize is betting that fluctuations and increases in energy prices will grow faster than the cost of upgrading buildings to be more efficient and lower-emissions, making its strategy profitable in the long-term.
While I’ve long followed thermal battery companies like Rondo and Antora, which use renewable energy to heat up hot rocks capable of delivering industrial heat, I was unaware of iron fuel’s potential to do much the same. That changed this week when the Dutch startup Rift announced it had raised $132 million to commercialize this technology.
The startup produces high-temperature heat by combusting iron powder with ambient air in a specialized boiler engineered to handle metal fuels. This process produces a flame that can reach 2,000 degrees Celsius without emitting any carbon dioxide. The resulting heat can then be delivered as steam, hot water, or hot air to industrial facilities, with the only byproduct being iron oxide (rust), which itself can then be collected and converted back into iron fuel by reacting it with hydrogen produced via low-carbon processes.
Rift’s latest funding comprises a $96.2 million Series B round involving several Netherlands-based investors, along with a $35.5 million grant from the EU Innovation Fund. Both pots of money will support the construction of the company’s first production facility for iron fuel boilers. Rift’s first customer is the building materials manufacturer Kingspan Unidek, with whom it’s developing a project that Rift says will result in over a million metric tons of avoided emissions over a 15-year period.
The electric vehicle transition looks pretty different in East Africa, where two-wheeled motorcycles dominate daily commuting and urban transit. These smaller, lighter vehicles are simple and cheap to electrify, and while their upfront cost is higher than gasoline-powered bikes, operating expenses can be 50% lower. This week, the market received a boost as e-motorbike startup Zeno announced a $25 million Series A round to scale production of its flagship bike.
The round was led by the climate tech VC Congruent Ventures, with support from other heavyweights such as Lowercarbon Capital. Zeno’s CEO Michael Spencer, who left Tesla in 2022 to start the company, sees a larger electrification opportunity in emerging economies than here in the U.S. As he told TechCrunch when Zeno emerged from stealth in fall 2024, “the Tesla master plan has more legs and more room to run with lower hurdles in emerging markets.”
Spencer saw particular potential to sell low-cost motorbikes with batteries that Zeno would own rather than the customer, meaning they can’t charge their bikes at home. Riders instead rely on swap stations where they can exchange depleted batteries for fully charged ones — much as the Chinese electric vehicle company Nio does with its cars.
Zeno designs and manufactures its own bikes and charging infrastructure, with 800 motorbikes sold and 150 charging and battery-swap stations installed across four cities across Kenya and Uganda. With this latest influx of cash, the company plans to fulfill its backlogged orderbook, which it says now has more than 25,000 retail and fleet customers.
Data centers developers are hitting bottlenecks securing energy, land, and social acceptance — so the startup Aikido wants to ship them out to sea, where it says “energy, cooling and space are abundant.” This week, the offshore wind developer revealed its novel floating turbine platform, designed to co-locate wind generation and battery storage with data centers submerged in compartments connected to the turbine itself.
The installation would still be grid-connected, but the idea is that the turbine and batteries will meet most of the data center’s energy needs, drawing on the grid mainly during the summer when the wind dies down. A 100-kilowatt proof of concept is already being developed in Norway, with the first commercial deployment slated for the U.K. sometime in 2028. Eventually, Aikido says it envisions building “gigawatt-scale” data centers at sea — an ambitious undertaking in a notoriously harsh environment.
But as CEO Sam Kanner reasoned in a press release, “before we go off-world, we should go offshore” — a likely jab at Elon Musk, who has repeatedly expressed his desire to launch data centers into space to rid himself of terrestrial concerns over real estate and energy.

Co-founder Mateo Jaramillo described how the startup’s iron-air battery could help address the data center boom — and the energy transition
Well before the introduction of ChatGPT and Claude, Ireland underwent a data center construction boom similar to the one the U.S. is experiencing today.
That makes it a fitting location for Form Energy’s first project outside the U.S. Mateo Jaramillo, the CEO of the long-duration energy storage startup, described Ireland as “a postcard from the future” at Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week.
In a one-on-one interview with Robinson Meyer, Jaramillo went on to explain the potential of a 100-hour battery, calling it the duration at which you can “functionally replace thermal resources on the grid or compete with them.” Such storage capacity would not only bolster data centers’ power reliability but also speed up the transition from oil and gas to renewables.
Form Energy, which Jaramillo co-founded in 2017, is best known for its iron-air battery that can continuously discharge energy for 100 hours. In February, the startup announced a partnership with Google and the utility Xcel Energy to build the highest-capacity battery in the world, capable of storing 30 gigawatt-hours of energy, as Heatmap’s Katie Brigham reported.
Despite the troublesome state of renewables deployment in the U.S., energy storage firms like Form appear to be doing well, thanks to record load growth. “When we founded the company, we didn’t anticipate the boom of data center demand that we’re currently experiencing,” said Jaramillo. “But we did bet on the overall mega-trend being pretty firmly in place, which is electricity growth.”
In addition to load growth, battery manufacturers are still benefiting from the Inflation Reduction Act’s energy storage tax credits, which survived the deep cuts Republicans made to the signature climate law last summer. Jaramillo noted that customers can still claim a tax credit for purchasing energy systems, while a manufacturing protection credit also remains in place. “We absolutely qualify for both those things,” Jaramillo said. “In fact, 100 hours as a duration is written into the legislative text for the manufacturing [tax credit].”
Though batteries can help accelerate the retirement of natural gas plants by providing firm energy to supplement renewables’ generation, politicians’ fear of load growth seems to have forged a bipartisan consensus supporting batteries. For its part, Form Energy is focused on continuing to drive down the cost of its iron-air battery.
From “where we sit today,” Form Energy is “quite confident that we will hit that roughly $20 a kilowatt-hour cost within a very short period of time,” Jaramillo said.
At San Francisco Climate Week, John Reynolds discussed how the state is juggling wildfire prevention, climate goals, and more.
Blessed with ample sun and wind for renewables but bedeviled by high electricity prices and natural disasters, California encapsulates the promise and peril of the United States’ energy transition.
So it was fitting that Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week, kicked off with John Reynolds, president of the California Public Utilities Commission.
The CPUC oversees the most-populous state’s utilities and has the power to approve or veto electricity and natural gas rate increases. At Heatmap House, Reynolds — “one of California’'s most important climate policymakers,” as Heatmap’s Robinson Meyer called him — affirmed that affordability has been top of mind as power bills have risen to become a mainstream political issue across the country. California’s electricity prices are the second-highest in the nation, behind only Hawaii, according to the Electricity Price Hub.
“I’d really like to see us drive down the portion of household income that is consumed by energy prices,” Reynolds said in a one-on-one interview with Rob. “That’s a really important metric for making sure that we’re doing our job to deliver a system that’s efficient at meeting customer needs and is able to support the growth of our economy.”
The Golden State’s power premium has been exacerbated by the fallout from multiple wildfires that have devastated various parts of the state in recent years, which have necessitated costly grid upgrades such as undergrounding power lines. California-based utility PG&E has also invested in more futuristic fire solutions such as “vegetation management robots, power pole sensors, advanced fire detection cameras, and autonomous drones, with much of this enhanced by an artificial intelligence-powered analytics platforms,” as Heatmap’s Katie Brigham wrote shortly after last year’s fires in Los Angeles.
Affordability affects not just Californians’ financial wellbeing, but also the state’s ability to decarbonize quickly. “The affordability challenge that we’re seeing in electric and gas service is one that is going to make it more difficult to meet our climate goals as a state,” Reynolds said.
One contentious — and somewhat byzantine — aspect of California’s energy transition is how much of a financial incentive the CPUC should offer for residents to install rooftop solar. Net metering is a billing system that rewards households with solar panels for sending excess generation back to the grid. Three years ago, the CPUC adopted a new standard that substantially lowered the rate at which solar panel users were compensated.
“We had to slow the bleeding,” Reynolds said, referring to the greater financial burden paid by utility customers without solar panels. “The net billing tariff did slow the bleeding, but it didn’t stop it.”
Asked whether he is focused more on electricity rates (the amount a customer pays per kilowatt-hour) or bills (the amount a utility charges a ratepayer), Reynolds said both are important.
“If we can drive down electric rates, we’re going to enable more electrification of transportation and of buildings,” Reynolds said. “It’s really important to look at bills, because that is fundamentally what hits households. People’s wallets are limited by their bills, not by their rates.”
The state has terminated an agreement to develop substations and other necessary grid infrastructure to serve the now-canceled developments.
Crucial transmission for future offshore wind energy in New Jersey is scrapped for now.
The New Jersey Board of Public Utilities on Wednesday canceled the agreement it reached with PJM Interconnection in 2021 to develop wires and substations necessary to send electricity generated by offshore wind across the state. The board terminated this agreement because much of New Jersey’s expected offshore wind capacity has either been canceled by developers or indefinitely stalled by President Donald Trump, including the now-scrapped TotalEnergies projects scrubbed in a settlement with his administration.
“New Jersey is now facing a situation in which there will be no identified, large-scale in-state generation projects under active development that can make use of [the agreement] on the timeline the state and PJM initially envisioned,” the board wrote in a letter to PJM requesting termination of the agreement.
Wind energy backers are not taking this lying down. “We cannot fault the Sherrill Administration for making this decision today, but this must only be a temporary setback,” Robert Freudenberg of the New Jersey and New York-focused environmental advocacy group Regional Plan Association, said in a statement released after the agreement was canceled.
I chronicled the fight over this specific transmission infrastructure before Trump 2.0 entered office and the White House went nuclear on offshore wind. Known as the Larrabee Pre-Built Infrastructure, the proposed BPU-backed network of lines and electrical equipment resulted from years of environmental and sociological study. It was intended to connect wind projects in the Atlantic Ocean to key points on the overall grid onshore.
Activists opposed to putting turbines in the ocean saw stopping the wires as a strategy for delaying the overall construction timelines for offshore wind, intensifying both the costs and permitting headaches for all state and development stakeholders involved. Some of those fighting the wires did so based on fears that electromagnetic radiation from the transmission lines would make them sick.
The only question mark remaining is whether this means the state will try to still proceed with building any of the transmission given rising electricity demand and if these plans may be revisited at a later date. The board’s letter to PJM nods to the future, asserting that new “alternative pathways to coordinated transmission” exist because of new guidance from the Federal Energy Regulatory Commission. These pathways “may serve” future offshore wind projects should they be pursued, stated the letter.
Of course, anything related to offshore wind will still be conditional on the White House.
