Greentown Labs, after announcing its CEO is stepping down at the end of the month, has named the climatetech incubator's interim leader.

Kevin Dutt, a recently named member of Greentown's board of directors based in the Boston area, has been appointed interim CEO. The decision, made by the board, is effective July 8. Dutt is a management consultant at Sustainable Edge Consulting, as well as an environmental entrepreneur, executive, and adviser with 25 years of experience.

"We continue to believe deeply in Greentown and are proud to have one of our board members step into this role before our next long-term CEO is identified," the nonprofit writes in the announcement. "We are confident Kevin is best suited to lead Greentown through this time of transition—his experience in climate and sustainability, philanthropy, and venture will play a key role in helping seamlessly guide Greentown in the coming months."

Dutt will lead the organization, which has dual locations in Houston and Somerville, Massachusetts, following outgoing CEO and President Kevin Knobloch. Knobloch announced in May that he will be stepping down after less than a year in the position. He was named CEO last September, previously serving as chief of staff of the United States Department of Energy in President Barack Obama’s second term.

The news of Knobloch's departure came just over a month after the organization announced that it was eliminating 30 percent of its staff, which affected 12 roles in Boston and six in Houston.

Dutt is the fourth person to take the help of Greentown since Emily Reichert, who held the position from 2013 to 2022, stepped down. Prior to Knobloch's appointment, Greentown's Co-Founder Jason Hanna and former CFO Kevin T. Taylor, who each served in an interim capacity.

Applications open for inclusive cleantech accelerator

appy now

Calling all cleantech startups founded by innovators of color — an inclusive accelerator program is now accepting applications.

Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, has opened applications for it's second cohort. The program — from Greentown Labs and Browning the Green Space — provides access to funding, networking connections, incubation space, mentorship, resources, and opportunities for energy tech founders of color for a year.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” Greentown Labs CEO and President Kevin Knobloch says in a news release. “We are eager to expand upon the great success and momentum of year one, and to welcome another incredible cohort of BIPOC-led startups that are developing much-needed climatetech solutions. We’re equally committed to helping these companies accelerate and deploy their solutions, while also helping to build a more diverse, inclusive climatetech workforce—ACCEL sits at the nexus of those two critical efforts.”

The program, supported by the Massachusetts Clean Energy Center, accelerated six startups this year — Active Surfaces, DrinKicks, EarthBond, florrent, frakktal, and SpadXTech.

“The ACCEL Program directly aligns with our mission to ensure that climatetech jobs and wealth creation opportunities are available to all residents of the Commonwealth,” Emily Reichert, CEO at MassCEC and former CEO at Greentown, says in the release. “We are excited to see the second round of this important program, with our Equity Workforce Fund support fostering a partnership between Greentown Labs and Browning the Green Space aimed at accelerating the growth of minority and women business enterprises in Massachusetts.”

ACCEL, which doles out $25,000 in non-dilutive grant funding to each participant, is also supported by Boston-based Barr Foundation and provides programming from VentureWell, a nonprofit with expertise in climatetech.

“Through our partnership with Greentown and VentureWell, we are able to put our respective strengths together to create an ambitious program to bolster founders of color in climatetech and propel innovations that benefit communities most impacted by climate change,” Kerry Bowie, executive director and president of Browning the Green Space, says in the release. “Opening applications for Year 2 of ACCEL is an important milestone in strengthening critical support for traditionally excluded entrepreneurs in our communities.”

Applications for ACCEL are open until January 5, 2024. While entrepreneurs from anywhere can apply, preference will be given to applicants in Greater Boston and Greater Houston, where Greentown’s incubators are located.

at the helm

The largest climatetech incubator in North America has named an Obama Administration appointee as its next CEO.

Kevin Knobloch, who served as chief of staff of the United States Department of Energy in President Barack Obama’s second term, will be CEO of Greentown Labs, effective September 5. In his role, Knobloch will oversee both Greentown locations in Houston and Somerville, Massachusetts, outside of Boston.

“Kevin has a proven and impressive track record of growing, operationalizing, and leading a dynamic mix of organizations at different stages and in various industries, all of which have aligned with his unwavering commitment to addressing the climate crisis,” Greentown Labs Board Chair Dawn James says in a news release. “On behalf of the entire Board of Directors, I am thrilled to welcome Kevin as our next CEO. We are excited for what is to come under Kevin’s leadership and look forward to the positive impact he will undoubtedly have on our team, our startup community, and the ecosystem at large.”

With 30 years of experience across sectors, Knobloch most recently served as president of Knobloch Energy, an independent advisory and consulting firm. He also served as acting executive director of the National Offshore Wind Research & Development Consortium from June through December 2022. From 2018 to 2020, Knobloch was president of New York OceanGrid LLC, where he led Anbaric’s efforts to develop offshore wind transmission in New York.

“I’m honored and thrilled to have the opportunity to once again pass the leadership baton,” Greentown Co-Founder Jason Hanna says, who has been serving as interim CEO. “Especially so given Kevin’s incredible record of climate leadership. I’m excited for the future of this organization and the impact he can make as Greentown enters the second decade of its climate mission.”

The appointment follows an executive search that began after Greentown's previous CEO Emily Reichert announced she was stepping down in December.

“I’m delighted to be asked by Greentown Labs’ Board of Directors to be the next leader of this highly effective organization—and very excited to get to work,” Knobloch says in a statement. “I’ve long admired the critical role Greentown plays in supporting the growth and impact of early-stage climate and energy transition technology companies, as well as the impressive efforts by former longtime CEO Emily Reichert and the talented Board and staff to build Greentown into a national powerhouse and model for other incubators around the world. The climate crisis demands that we accelerate our collective pace of deployment and I look forward to collaborating with our startups, staff, and partners to support that acceleration.”

The announcement comes on the heels of Greentown naming its inaugural Houston general manager. Timmeko Moore Love was named to that new position last week.

Greentown Labs names inaugural Houston general manager

at the helm in hou

Greentown Houston has a new leader at its helm.

The climatetech incubator, dual located in Houston and Somerville, Massachusetts, has named Timmeko Moore Love as Houston general manager and senior vice president of Greentown Labs. She'll lead Greentown Houston’s team and business operations, while growing the location's membership.

“We are thrilled to have Timmeko joining our leadership team,” says Jason Hanna, co-founder and interim CEO of Greentown Labs, in a news release. “Her wealth of experience will be instrumental in helping Greentown Houston maximize its impact through operational excellence, while inspiring and accelerating climate entrepreneurship from the energy capital of the world.”

Love has 20 years of experience in innovation management, per the news release, and was the first Black woman at a Fortune 500 to lead a venture capital program. In that role, which was at The Woodlands-based Entergy Corp., she was named to the 2020 Global Corporate Venturing Powerlist. Love also oversaw corporate ventures at Mayo Clinic and Best Buy Capital.

“Greentown Labs is committed to ensuring founders’ success and is an agent of action in the fight against climate change,” says Love in the release. “I am excited to continue my service to the Greater Houston climate innovation ecosystem through this esteemed platform, and partner internally and externally to evolve and expand our services and programs.”

Juliana Garaizar, who originally joined Greentown as launch director ahead of the Houston opening in 2021, previously oversaw the day-to-day operations of Greentown Houston. In January, she was promoted from vice president of innovation to chief development and investment officer. She shared with InnovationMap that Greentown was looking to hire its first Houston manager.

"Now that we are more than 80 members, we need more internal coordination," she told InnovationMap at the time. "Considering that the goal for Greentown is to grow to more locations, there's going to be more coordination and, I'd say, more autonomy for the Houston campus."

Greentown Labs is currently undergoing a search for its next CEO to succeed Emily Reichert, who stepped down in December.

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.
