It's been officially a year since the Inflation Reduction Act was enacted, so it's no surprise that looking at the IRA's impact dominated the discussion at a recent industry event.

The second annual Renewable Energy Leadership Conference, presented by Renewable Energy Alliance Houston and Rice Business Executive Education, featured thought leadership from 20 experts on Tuesday, August 22. While some panels zeroed in on hiring and loan options for energy transition companies, the day's program kicked off with a couple panels looking both back and forward on the IRA.

When looking at the IRA's impact, the experts identified a few key things. Here's what they said at the conference.

Going beyond tax credits and regulation

Greg Matlock, EY's global energy and resources industry tax leader, kicked off the IRA discussion after John Berger, CEO of Sunnova, gave a keynote address.

Matlock set the scene for the IRA, explaining that previous legislation incentivizing clean energy changes mostly stayed within regulation and tax credits. Credits as a tax policy fail to incentivize organizations that are, for various reasons, are tax exempt or are already paying insignificant taxes. The fundamental switch of the IRA was to a "want to" rather than a "have to."

"Everyone has had aspirations, but with aspirations without capital, it's hard to get movement," Matlock says. "But what the IRA did was create a liquidity in the market and added access to an investor base. Now you're pairing aspirations and capital, and now you're seeing movement in the market."

The IRA, Matlock continues, also got the ball rolling on expanding requirements for tax incentives. Previously, a specific technology has to be clearly identified to be qualified for a credit. Moving forward, the IRA improved this qualification process and in the future, there will be be technology neutral incentives.

One thing Matlock also highlighted was the limitations of tax credits — dollar for dollar credit.

"Two years ago, if you called an organization that was tax exempt (about) a project that generates tax credits, why would that want that?" Matlock says. "For the first time, you can sell federal tax credits — not all of them — for cash and tax free to businesses who are paying taxes."

Explaining that there are limitations, Matlock says this process had a significant impact encouraging movement in this space — especially from surprising sources.

"We're seeing companies that have absolutely no connectivity to our energy industry making investments through the purchase of tax credits to fund the development of projects," Matlock says.

A focus on carbon capture and hydrogen

Matlock continues to explain how carbon capture and hydrogen became two case studies for the impact of the IRA.

Prior to the IRA, over 16 countries incentivized hydrogen production, he explains, and the United States was not one of them.

"With the signing of the IRA, we went from the worst to the first," Matlock says.

Carbon capture development was directed more at traditional energy industries. The IRA enactment represented a switch for these companies from regulatory moves to incentivization, which has been more effective in general, Matlock says.

Over the past year, according to the American Clean Power Association, more than $271 billion in investment in clean energy projects has occurred since the IRA was enacted. When it comes to jobs, over 170,000 clean energy jobs have been announced since the IRA.

Problematic permitting and pricing volatility 

In a subsequent panel, the three thought leaders looked at the IRA a bit more critically. While the IRA spurred momentum, it also shined a spotlight on some of the industry's challenges.

"The IRA for developers has been very positive. It provided certainty and allowed developers and investors alike to plan long term," says Omar Aboudaher, senior vice president of development for Leeward Renewable Energy. "With that comes challenges, including exacerbating some existing problems with permitting."

Aboudaher explains that the IRA-inspired burst of projects has caused a lot more permits for the increase of development. And, he adds, there's not a concentrated effort. It's happening in silos on the various levels of government.

"On the permitting side, there's a big need to streamline permitting," Aboudaher says. "In some parts of the country, it can take 6 to 10 years to permit your project."

On the investor side, it's also a problem, adds Fred Day, managing director of investments at Brookfield Asset Management.

"Even though we have this IRA, a lack of permitting reform does create a bottleneck," he says.

Another challenge is a disconnect between supply and demand. While the IRA has incentivized solar energy generation per hour of energy, meaning that its cheaper than ever to make energy via solar panels, there's not yet the demand infrastructure for this energy. This incentivization structure has already been in place for wind power.

"I think it's going to be a real problem. It's a real problem with wind today," Doug Moorehead, COO of Broad Reach Power, says, explaining that there's volatility in pricing. "When the wind is high, prices are really low. When wind is low, prices are high."

All of this is leading to an imbalance of market demand and supply, he continues. Jessica Adkins, partner at Sidley Austin LLP and moderator, adds that there's built in volatility for solar since solar energy is confined to the time of day when the sun is out.

"Any time you're incentivize to produce regardless of demand, it's going to be an issue," Moorehead says.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.

3 Houston-area companies named to Global Cleantech 100

Energized

Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023. Last year, the startup raised $32.3 million in venture capital. Also in 2025, Vaulted Deep signed a 12-year deal with software giant Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

Vaulted Deep also made the list last year, along with Houston-based Syzygy Plasmonics and Fervo Energy. Fervo was also named the 2025 North American Company of the Year by Cleantech Group.
