3 things to know about the IRA that impact Houston's energy sector

the view from heti

In August of 2022, President Joe Biden signed into law the Inflation Reduction Act which aims to mitigate inflation by reducing the federal government budget deficit and lowering prescription drug prices. Through federal funding and a combination of grants, loans, rebates, incentives and other investments, the IRA also will impact domestic energy production while bolstering efforts for an energy-abundant, low-carbon future.

At the bill’s one-year anniversary, Mitsubishi Heavy Industries America held a panel of leaders across multiple sectors — energy, finance, industry and academia — to discuss the IRA and what it means for the future of business and industries.

Here are three things to know about how the Inflation Reduction Act is driving a clear tech industrial revolution, according to Mitsubishi Heavy Industries:

1. IRA Encourages Private-Sector Investment

Since being passed into law by President Biden in August of 2022, the IRA’s first year yielded:

  • Companies have announced 96 gigawatts of new clean power over the previous eight months, enough to power almost 20 million homes – about one-seventh the total number of homes in the U.S.
  • Companies have announced enough new U.S. battery manufacturing projects to support production of more than 10 million EVs per year – more vehicles than were manufactured in the U.S. in 2021.
  • The IRA’s expected impact on private investment has increased between 50 percent and 200 percent from initial estimates, based on research from the Brookings Institution and Rhodium Group, with the largest jumps related to hydrogen, carbon capture, energy storage and critical minerals.

2. A strong focus on environmental justice

According to a fact sheet issued by the White House, the IRA will: reduce pollution; improve clean transit; make clean energy more affordable and accessible; and strengthen resilience to climate change. With a simple mission to accelerate the energy transition with incentives rather than penalties, the act will allocate nearly $400 billion to efforts to reach a low-carbon, energy abundant future including:

  • More than 40 percent of the $27 billion Greenhouse Gas Reduction Fund ($10.8 billion) will benefit low-income and disadvantaged communities.
  • $3 billion for states, tribes, municipalities and community-based nonprofit organizations for environmental justice and climate justice block grants. Eligible activities include mitigating climate risks from heat islands and wood heater emissions, and reducing indoor air pollution; climate resiliency; and facilitating engagement of disadvantaged communities.
  • $3 billion to reduce air pollution and emissions at ports via the installation of zero-emissions equipment and technology.
  • $37.5 million in grants to monitor and reduce air pollution and greenhouse gas emissions at schools in low-income and disadvantaged communities along with another $12.5 million to provide technical assistance to help schools address environmental issues.
  • $33 million to the Council on Environmental Quality to collect data and track disproportionate impacts of pollution and climate change on environmental justice communities in addition to $3 million in grants to deploy, integrate and operate air quality sensors in low-income and disadvantaged communities

3. Collaboration reimagined

As the race to net zero continues, tech giants and energy leaders across all sectors ––corporations, governments, nonprofits and academia –– have come together for one common goal: develop solutions to tackle the world’s toughest energy issues. When it comes to progressing the IRA, industry and Mitsubishi President and CEO Takajiro Ishikawa weighed in on collaboration for the act noting that “The energy transition can’t be done by just one party. Collaboration and communication between all parties is key.”

3 things to know this week: Energy startups announce big wins, evaluating the IRA's first year, and more

hou knew?

Editor's note: It's a new week — start it strong with three quick things to know in Houston's energy transition ecosystem. Three energy tech startups are celebrating big wins, experts evaluate the IRA's first year, and events not to miss this week.

Eyes on the IRA

August 16 marked one year of the Inflation Reduction Act's enactment, and many have taken this first anniversary as an opportunity to look back on its effectiveness and where it's fallen short.

For Carbon Clean, a United Kingdom-founded company, the IRA made all the difference in its expansion into the United States — by way of Houston.

"The impact of the IRA cannot be overstated for our industry, especially for point source carbon capture technology companies like Carbon Clean," Co-Founder, Chair, and CEO Aniruddha Sharma shares with EnergyCapital in an interview. "The momentum created by the law's passage, along with our existing activity in North America, led to the opening of our US headquarters in Houston in March this year. We will double our US headcount to meet demand for CycloneCC, our breakthrough, fully modular carbon capture technology."

At a recent event at Rice University, experts zeroed in on the effect on clean energy project development. While the IRA opened doors for new funding, it also revealed shortcomings when it came to permitting.

"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."

Houston experts evaluate the impact of the IRA on cleantech project development

one year later

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.

Why this UK carbon capture co. expanded to Houston, IRA's impact, and more

Q&A

Earlier this year, a growing carbon capture company announced its new North American headquarters in Houston. Now, the company is focused on doubling it's headcount before the end of 2023 to meet demand.

Carbon Clean, which has a technology that has captured nearly two million tons of carbon dioxide at almost 50 sites around the world, opened its new office in the Ion earlier this year. The company is now building out its local supply chain with plans to rapidly expand.

In an interview with EnergyCapital, Co-Founder, Chair, and CEO Aniruddha Sharma weighs in on the new office, how pivotal the Inflation Reduction Act has been for his company's growth, and the future of Carbon Clean.

EnergyCapital: Looking back on the past year since the Inflation Reduction Act was enacted, what has the impact been on Carbon Clean?

Aniruddha Sharma: The IRA did much to jolt industry, incentivizing investment in carbon capture, while also telegraphing that the US government is getting serious about bringing emissions down. Overnight, the US became Carbon Clean's biggest growth opportunity: inquiries from industrial emitters leapt a staggering 64 percent.

The impact of the IRA cannot be overstated for our industry, especially for point source carbon capture technology companies like Carbon Clean. The momentum created by the law's passage, along with our existing activity in North America, led to the opening of our US headquarters in Houston in March this year. We will double our US headcount to meet demand for CycloneCC, our breakthrough, fully modular carbon capture technology.

EC: What does the sector still need to see — in terms of support from the government — to continue to move the needle on the energy transition?

AS: There's much to admire in the way that the IRA incentivizes business. While it involves billions of dollars of public investment, it is set up in such a way that companies must make substantial investments first. IRA funding doesn't arrive on day one — it comes over several years and to get to the first dollar of funding, a company must secure considerable private investment first. In other words, every single dollar of the IRA funding is unlocking additional private investment, creating high-paying jobs, and bringing manufacturing back home.

Of course, a lot of additional investment still needs to happen, and for some harder-to-abate sectors additional policy measures may be required to enable deployment at scale. The IRA is just a first step, but what a giant step it promises to be.

EC: You recently opened Carbon Clean's HQ in Houston. What's next for your company in terms of growth — especially here in Houston?

AS: We're experiencing phenomenal growth globally, but we expect our expansion in North America to outpace all other regions. In line with this, we've seen a surge in interest from industrials across the US and our newly-opened Houston office will help us to meet this demand.

We are establishing a very significant base in the US — doubling our headcount this year — and we are developing a local supply chain to support the commercialization of our breakthrough modular technology, CycloneCC.

The potential for CycloneCC in the US and Houston area is huge. It is optimised for low to medium scale industrial emitters and recent Rice University research on the US Gulf Coast, for example, found that it is well suited to 73% of Gulf Coast emitters.

We're currently working with Chevron on a carbon capture pilot for our CycloneCC technology on a gas turbine in San Joaquin Valley, California. We expect to be announcing additional carbon capture projects in the US in the coming months.

New 160MW battery storage project comes online in Houston

powered on

Colorado-based energy storage company SMT Energy and North Carolina-based software company FlexGen have begun operations of Houston IV, a 160-megawatt utility-scale battery storage facility that aims to support the ERCOT grid.

The companies delivered the project in just six weeks, according to a news release. Mississippi-based Irby Construction Company served as the engineering, procurement, and construction (EPC) partner, and CenterPoint Energy will serve as the interconnecting utility.

“FlexGen’s distinctive combination of software automation, our remote operations center, and on-the-ground field expertise all work together to accelerate battery deployment,” Jason Rislov, SVP of operations at FlexGen, said in the release. “What used to take 25-plus weeks took us six. That time saved translates directly into giving the grid and consumers what they need most right now: a more reliable, resilient energy system.”

Houston IV is one of more than 12 projects that SMT and FlexGen have built to connect to ERCOT, according to Energy Storage News.

“Bringing a 160-MW battery storage facility online in just six weeks required disciplined planning, seamless coordination, and an unwavering focus on safety and quality,” Shaun Coleman, project manager at Irby Construction, said in a news release. “The SMT Energy, FlexGen, and Irby Construction teams coordinated engineering, procurement, and construction to keep every workstream aligned, identify challenges early, and maintain safety and quality at an accelerated pace. That integration is critical, not only to delivering projects quickly, but also to ensuring battery storage facilities perform reliably over the long term.”

Houston IV is expected to store and provide enough electricity to power 8,800 homes in Texas annually. In March, SMT Energy secured $135 million in funding for the project from Macquarie and KeyBanc Capital Markets as joint lead arrangers. SMT and FlexGen broke ground to signal the start of the process in May.

In 2023, SMT Energy and joint venture partner SUSI Partners also announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.
