Houston solar company expands in Puerto Rico, receives DOE funding

island opportunities

A Houston renewable energy company has announced two initiatives that are hoping to provide more grid stability on the island of Puerto Rico.

Sunnova announced that it's expanding its Sunnova Sentient Virtual Power Plant platform. The company has also been selected by the United States Department of Energy’s Grid Deployment Office to be a part of a $440 million investment from the Puerto Rico Energy Resilience Fund.

Sunnova's VPP platform is expanding in Puerto Rico through a collaboration between the Sunnova Power Flex Program and LUMA's Customer Battery Energy Sharing program in Puerto Rico. This plan is "to transform the role of distributed solar and storage customers in enhancing grid stability during peak demand periods, all while offering them financial incentives for their participation," according to Sunnova's release.

Puerto Rican residents can opt into the Sunnova Flex Power Program and will be compensated for the power supplied by their batteries. According to Sunnova, a battery could earn up to $1,000 for this first pilot year.

“We are incredibly excited about the possibilities that our industry-leading VPP platform—delivered to our customers through our Sunnova Flex Power Program—holds for the people of Puerto Rico,” John Berger, CEO of Sunnova, says in the release. “As we continue to spearhead the transition towards a cleaner and more robust future, extending our VPP platform will not only help reshape the energy landscape in Puerto Rico but also empower our valued customers to play an integral role in bolstering grid stability. We eagerly anticipate the transformative impact this program will have on our customers and the Puerto Rican community at large.”

Sunnova has 52,000 solar and storage customers on the island and has installed storage to a capacity of 800 MWh.

“We're excited to collaborate with Sunnova on this important initiative, which signifies a major step in our ongoing efforts to enhance energy reliability for Puerto Rico. We're dedicated to achieving a more stable energy supply, reducing disruptions, and securing a resilient energy future, ultimately benefiting the people of Puerto Rico,” Jessica Laird, VP of Customer Experience at LUMA, says in the statement.

Sunnova's selection by the DOE Grid Deployment Office makes the company one of the eight to receive chunk of a $440 million commitment to install rooftop solar and batteries in PR.

Houston expert on importance of messaging when scaling an energy transition company

comms 101

Each phase of the company represented different challenges for Hultberg and her communications team. As she explains on the podcast, consistently conveying a strong message is key in any industry, but especially energy.

"Communication is critical," Hultberg says, "having a strategy and really being able to articulate who you are, what you stand for, what is your mission, what is your vision — and really beyond that, what is your strategy for how you move forward. ... You can never say the same thing to the same people too many times, especially when you're a company that some people have never heard of before."

And while there's a unique challenge to communications for energy transition companies, Hultberg says she views it as a huge opportunity as long as you have the right structure in place.

"Of course communications and being as strategic as possible with the story that you're telling and the narrative that you're weaving for your different audiences, but then you layer on an industry that's rapidly changing and is tumultuous at times," she says. "Being able to come back to the core mission and values is really incredible."

Hultberg says that when she originally joined the team in 2017, she thought a solar energy company in Houston was an interesting choice — and it was. Texas was not one of Sunnova's biggest markets at the time, Hultberg explains, but things are different now.

"Over the last couple of years, especially after Winter Storm Uri, where you saw a lot of people go without power. ... We had a lot of customers say, 'That can't happen again,'" she says. "You're seeing the adoption and uptick in solar in storage because they are looking for grid reliability and affordability and they aren't getting it from their utility providers."

MIT Technology Review released its list of 15 Climate Tech Companies to Watch this year, and Fervo Energy, a Houston-based, rapidly scaling geothermal energy company made the cut.

"Fervo’s enhanced geothermal approach promises to significantly expand the areas where we could tap into the carbon-free and nearly limitless source of energy beneath our feet. Geothermal offers the added advantage of generating electricity around the clock and calendar, making it an ideal clean source to fill in the gaps as grids increasingly come to rely on fluctuating renewables like solar and wind," reads the writeup on the company.

"It could provide a much cheaper or less controversial way of fixing that fundamental challenge in cleaning up the grid than building giant battery plants or adding nuclear power reactors, respectively," the MIT Technology Review continues.

Fervo, which announced earlier this year that its commercial pilot project has resulted in continuous carbon-free geothermal energy production, has raised $187 million since it was founded in 2017.

The article points to not only the accomplishments of the startup, but also the challenges it faces, including further proving out its technology's "effectively, affordably, and consistently on larger scales."

Houston hosted the inaugural Energy + Climate Startup Week in September, which brought together leading energy and climate venture capital investors, industry leaders and startups from around the world to showcase the most innovative companies and technologies that are transforming the energy industry while driving a sustainable, low-carbon energy future.

Repsol was one of the inaugural sponsors for the weeks kick off event that hosted several leading startups. This year marked 25 years of energy innovation for Repsol in the United States. As the energy landscape evolves, Repsol has committed to significant growth in renewable capacity, with an impressive 720 MW of solar and storage capacity already operational and 1.5 GW under construction.

Caton Fenz, CEO for Repsol’s Renewables North America shares more about Repsol’s approach to expanding its renewable footprint, integrating green energy into its core business and leveraging Houston’s unique role as a leader in the energy transition. Here’s an inside look at Repsol’s milestones and future goals in the journey toward decarbonization and a sustainable energy future.

Can you tell us more about Repsol’s strategy for expanding its renewables business?

This year Repsol is celebrating 25 years of energy development in the United States. Across the US, we have a team of more than 800 employees, with more than 130 employees working in the renewables business specifically.

Repsol’s growth ambition in the US renewable energy market is significant. Since launching our renewables activity in the US three years ago, we have installed more than 720 MW of solar generation and energy storage capacity. Today we have more than 1.5 GW of additional solar and energy storage capacity under construction, and more than 20 GW of solar, wind and energy storage in development across 13 states.

How does Repsol plan to integrate renewable energy sources into its broader business model?

Repsol Renewables operates in accordance with Repsol’s values and strategies. Renewable energy generation is one of the pillars of Repsol’s decarbonization strategy. Repsol will invest between €3 and 4 billion to organically develop its global project portfolio and aims to reach between 9,000 MW and 10,000 MW of installed capacity by 2027. Of this, 30% will be in the United States.

With these objectives in mind, we have been able to accelerate the development of wind, solar, and energy storage across the US market and the globe. By expanding our renewable energy business, we can further meet record demand growth for renewable energy.

What are the key projects or milestones that have been achieved within Repsol’s renewables portfolio so far?

Earlier this year, we announced the commercial operation of Frye Solar, our largest solar project worldwide. This project, located in Swisher County, Texas, has a total capacity of 637 MW. And as noted above, we have an additional 1.4 GW of projects under construction currently. These major energy infrastructure projects are indicative of the scale of our operations in the US.

University of Houston secures $3.6M from DOE program to fund sustainable fuel production

freshly granted

A University of Houston-associated project was selected to receive $3.6 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy that aims to transform sustainable fuel production.

Nonprofit research institute SRI is leading the project “Printed Microreactor for Renewable Energy Enabled Fuel Production” or PRIME-Fuel, which will try to develop a modular microreactor technology that converts carbon dioxide into methanol using renewable energy sources with UH contributing research.

“Renewables-to-liquids fuel production has the potential to boost the utility of renewable energy all while helping to lay the groundwork for the Biden-Harris Administration’s goals of creating a clean energy economy,” U.S. Secretary of Energy Jennifer M. Granholm says in an ARPA-E news release.

The project is part of ARPA-E’s $41 million Grid-free Renewable Energy Enabling New Ways to Economical Liquids and Long-term Storage program (or GREENWELLS, for short) that also includes 14 projects to develop technologies that use renewable energy sources to produce sustainable liquid fuels and chemicals, which can be transported and stored similarly to gasoline or oil, according to a news release.

Vemuri Balakotaiah and Praveen Bollini, faculty members of the William A. Brookshire Department of Chemical and Biomolecular Engineering, are co-investigators on the project. Rahul Pandey, is a UH alum, and the senior scientist with SRI and principal investigator on the project.

Teams working on the project will develop systems that use electricity, carbon dioxide and water at renewable energy sites to produce renewable liquid renewable fuels that offer a clean alternative for sectors like transportation. Using cheaper electricity from sources like wind and solar can lower production costs, and create affordable and cleaner long-term energy storage solutions.

“As a proud UH graduate, I have always been aware of the strength of the chemical and biomolecular engineering program at UH and kept myself updated on its cutting-edge research,” Pandey says in a news release. “This project had very specific requirements, including expertise in modeling transients in microreactors and the development of high-performance catalysts. The department excelled in both areas. When I reached out to Dr. Bollini and Dr. Bala, they were eager to collaborate, and everything naturally progressed from there.”

The PRIME-Fuel project will use cutting-edge mathematical modeling and SRI’s proprietary Co-Extrusion printing technology to design and manufacture the microreactor with the ability to continue producing methanol even when the renewable energy supply dips as low as 5 percent capacity. Researchers will develop a microreactor prototype capable of producing 30 MJe/day of methanol while meeting energy efficiency and process yield targets over a three-year span. When scaled up to a 100 megawatts electricity capacity plant, it can be capable of producing 225 tons of methanol per day at a lower cost. The researchers predict five years as a “reasonable” timeline of when this can hit the market.

“What we are building here is a prototype or proof of concept for a platform technology, which has diverse applications in the entire energy and chemicals industry,” Pandey continues. “Right now, we are aiming to produce methanol, but this technology can actually be applied to a much broader set of energy carriers and chemicals.”
