Local and state leaders shared updated plans this month on a first-of-its-kind structure that uses art to generate solar energy.

Slated to be located at Mason Park in Houston’s East End, the new "Arch of Time" is a freestanding sundial art installation that will generate 400,000 kilowatt-hours of power per year using 60,000 solar photovoltaic cells on its south-facing exterior.

The project will be part of a larger pavilion at the park and is being led by the renewable energy organization Land Art Generator Initiative (LAGI). Architect Riccardo Mariano will design the space. It will be funded by donations and cost $20 million, organizers say.

The project, originally known as "Arco del Tiempo," was announced in 2023. At the time, the city shared the installation would be installed at Guadalupe Plaza Park in 2024.

The project's latest update was announced during Houston City Hall’s Earth Day 2025, where organizers described it as "a monument to Houston's past, present, and future leadership as the energy capital of the world."

The 100-foot structure will also serve as a 25,000-square-foot shaded area, or microclimate, during hot days. It will also feature a stage performance space and a power hub for emergencies. Due to the artwork's north opening and south narrowing, it is also expected to help channel the breezes, according to LAGI.

The organization says it is also expected to generate enough power to fuel all of Mason Park.

“Mason Park will soon, perhaps become the first major park in the country that is powered entirely by the sun,” Houston City Council Member Joaquin Martinez said at the news conference. “The economic benefits are clear.”

Former Houston Park and Recreation director Joe Turner selected the East End park as the location of the arch and believes it could be used as a STEM tool for students.

“All the STEM education that can come from the way we use the solar collectors, the way it has a water collection system that's going to collect the runoff water, there's so much we can do to teach kids STEM,” said in a Houston Park and Recreation Department video.

The project is about two years away from being completed. LAGI says the Arch of Time will be the “first public art project of its scale to stand as a net-positive contribution to a sustainable climate.”

A Japanese air conditioner manufacturer has teamed up with the city of Houston on an energy efficiency initiative.

Daikin Comfort Technologies, which has its 4.2 million-square-foot Daikin Texas Technology Park in Waller, Texas, has partnered with the city of Houston to provide advanced air conditioning and heating solutions to help homeowners with energy efficiency and general comfort.

The company will install up to 30 horizontal discharge inverter FIT heat pump units over the next three years. The units will be provided to low-to-moderate-income households, which will include seniors over the age of 62, and homes renovated through the Housing and Community Development Department’s Home Repair Program. The new units will offer internet connectivity for remote monitoring and control. The installations align with Houston's Home Repair Program reconstruction plans.

“We are proud to partner with the City of Houston to launch this program that can directly advance their vision for decarbonization and increasing grid resiliency through higher efficiency,” CEO Satoru Akama says in a news release. “Through this program, Homeowners will have a premium system that will not only provide comfort but save on their monthly bills and do so in a way that lowers site emissions of CO2 compared to traditional, non-inverter systems. At Daikin, we are focused on changing the culture of air conditioning in North America and are looking forward to having a direct impact in our hometown.”

The initiative coincides with the company’s 100th year anniversary and National Air Condition Appreciation Days, which was coined by Mayor John Whitmire on August 13. Air Conditioning Appreciation Days ran from July 3 until August 15.

“The city thanks Daikin for this collaboration. Houstonians, especially seniors, (that) must have the resources to stay comfortable during extreme temperatures,” Whitmire adds. “This partnership reflects our dedication to caring for the well-being of our community.”

Awareness is part of the appreciation days, as Daikin recommends homeowners and facilities to clean filters, schedule maintenance checkups and look at ways to lower energy use.

“Through these new energy-efficient solutions, Daikin is helping the city promote a more sustainable environment for our community, and we are thankful for their example of how public-private partnerships can make a positive difference in society,” Houston Council Member Sallie Alcorn says in a news release.

City offers free composting services to Houstonians looking to reduce landfill contributions

do your part

The City of Houston Solid Waste Management Department is launching a free Food Waste Drop-Off pilot program through the end of February.

The program is in collaboration with Council Member Sallie Alcorn, Zero Waste Houston and the City of Houston Health Department, and allows residents to drop off food scraps at four different locations. The locations are:

  • Kashmere Multi-Service Center, Mondays from 2 to 5 pm
  • Acres Homes Multi-Service Center, Tuesdays from 2 to 5 pm
  • Alief Neighborhood Center, Wednesdays from 4 to 7 pm
  • Sunnyside Multi-Service Center, Thursdays from 3 to 6 pm

Houston residents, businesses, and institutions generate 6.2 million tons of municipal solid waste per year according to the Solid Waste Department program.

“You’ll find when you start composting your food scraps, there is a lot less trash generated in your home, at your curb, and taken to the landfill,” Alcorn says in a news release.

The Solid Waste Management Department provides solid waste services with the collection, disposal, and recycling of discarded material in an environmentally-friendly and cost effective way.

“The Solid Waste Department is eager to continue to provide innovative programs that divert waste from the landfill and actively engage Houston residents,” says Mark Wilfalk, Director of Solid Waste Management in the release.

Electric vehicles to take center stage at annual Houston event

vroom, vroom

Houston Auto Show, which is a long running event for auto enthusiasts, will feature its largest electronic vehicle representation to date this year.

The event will feature an EV Pavillion and Evolve Houston’s electronic showroom at the January 24 to 28 event at NRG Center. Attendees will have the opportunity to learn about what it means to go the EV route from environmental impact, performance, cost effectiveness, and other factors.

This year, vehicles like Nissan's Ariya Platinum+ AWD, Chevrolet’s Bolt EV, Ford’s F-150 Lightning and others will be on display at the EV Pavillion. CenterPoint Energy, Reliant, and the University of Houston were part of Evolve's 2023 showroom.

A recent study from SmartAsset ranked states with the most electric vehicle chargers by looking at the closest equivalent to a trip to the gas station, in terms of “refueling” – per capita. Texas is behind other similarly-sized states.

“Houston maintains some of the lowest population density and longest commute distances of major U.S. cities, and we have an immense amount of business and goods that flow through Houston,” Casey Brown, executive director and president of EVOLVE, previously told EnergyCapital. “We see a landscape that can uniquely achieve larger financial and environmental benefits of EV technologies. One way that we share these benefits is being the Presenting Sponsor of the Houston Auto Show.”

Houston Automobile Dealers Association Executive Vice President and event organizer RoShelle Salinas has noted there has been an uptick in EV demand for these events since the first one debuted at the 2020 show.

Evolve Houston, which was founded in 2018 through Houston’s Climate Action Plan, is one of the organizations leading the way in the EV space, as the company still aims for its goal to have half of the vehicles in the city be electric by 2030. Evolve assists and funds those looking to make the transition to electric with the Grant Tracker, which aims to make it easier to find funding opportunities, and assist with current grants available to organizations and individuals that are committed to a goal of zero emissions. The tracker serves as a tool to assist with purchasing an EV and charging equipment.

The Biden administration recently announced it is awarding $623 million in grants to help build an electric vehicle charging network across the nation. Grants will fund 47 EV charging stations and related projects in 22 states and Puerto Rico, including 7,500 EV charging ports according to officials. Texas is expected to see a chunk of that funding. Last year, the city of Houston approved $281,000 funding for the expansion of free electric vehicle rideshare services in communities that are considered underserved by utilizing services like RYDE and Evolve Houston.

“Evolve Houston has been a sponsor for 2 years and their display has been a great addition to the show because it is not only educational, but there is also a chance for people to test drive vehicles,” Salinas says.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

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.
