Greentown Labs has named the six participating climatetech startups for an accelerator for a global energy leader.

Shell and Greentown Labs announced the cohort for Greentown Go Make 2023 — a program designed to accelerate partnerships between startups and corporates to advance carbon utilization, storage, and traceability solutions with manufacturing in mind. Shell, which invests in net-zero and carbon-removal technologies, is hoping to strategically align with startups within carbon utilization, storage, and traceability across the energy transition spectrum.

“At Greentown Labs we recognize and appreciate the role energy incumbents must play in the energy transition, and we’re eager to facilitate meaningful partnerships between these impressive startups and Shell—not only to advance these technologies but also to help Shell achieve its sustainability goals,” Kevin Knobloch, CEO and President of Greentown Labs, says in a news release. “We know carbon utilization, storage, and traceability will play a critical role in our collective efforts to reach net-zero, and we’re enthusiastic about the potential impact these companies can have in that work.”

The cohort, selected from 110 applications, is co-located at Greentown's Houston and Somerville, Massachusetts, locations and includes:

  • Portland-based Caravel Bio is developing a novel synthetic biology platform that uses microbial spores and enzymes to create catalysts that are long-lasting and can withstand extreme conditions and environments.
  • Circularise, which is based in the Netherlands, is developing a blockchain platform that provides digital product passports for end-to-end traceability and secure data exchange for industrial supply chains.
  • Corumat, based in Washington, converts organic waste into high-performance, insulating, greaseproof, and biodegradable packaging materials.
  • Cambridge, Massachusetts-headquartered Lydian develops a fully electrified reactor that can convert a variety of gaseous, non-fossil feedstocks into pure syngas with high efficiency.
  • Maple Materials from Richmond, California is developing a low-cost electrolysis process to split carbon dioxide into graphite and oxygen.
  • Ontario, Canada-founded Universal Matter develops a proprietary Flash Joule Heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable circular economies.

The program, which includes $15,000 in non-dilutive stipend funding for each company, will work closely with Shell and Greentown over six months via mentorship, networking opportunities, educational workshops, and partnership-focused programming to support collaboration. Go Make 2023 concludes with a showcase event on March 27 at Greentown Labs’ Houston location.

This week, Shell announced another accelerator cohort it's participating in. The Shell GameChanger Accelerator, a partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), named four West Coast climatetech companies: DTE Materials, Hexas Biomass, Invizyne Technologies, and ZILA BioWorks. The program provides early-stage cleantech startups with access to experts and facilities to reduce technology development risk and accelerate commercialization of new cleaner technologies.

“Tackling the climate challenge requires multifaceted solutions. At Shell, we believe technology that removes carbon dioxide from the atmosphere will be essential for lowering emissions from energy and chemical products,” Yesim Jonsson, Shell’s GCxN program manager, says in a statement. “The companies in GCxN's sixth cohort embody these objectives and have the potential to usher in a more sustainable future.”

Apple announces 250,000-square-foot Houston factory as part of $500B plan

The Big Apple

As part of a more than $500 billion, four-year investment across the U.S., Silicon Valley tech giant Apple plans to build a factory in Houston that will produce servers for its data centers to support the company’s artificial intelligence (AI) business.

In a February 24 announcement, Apple says the company and its partners will build the 250,000-square-foot factory. The plant, set to open in 2026, will employ thousands of people. The announcement doesn’t mention where the plant will be located or how much the project will cost.

“Previously manufactured outside the U.S., the servers that will soon be assembled in Houston play a key role in powering Apple Intelligence, and are the foundation of Private Cloud Compute, which combines powerful AI processing with the most advanced security architecture ever deployed at scale for AI cloud computing,” according to the announcement.

Various media outlets report that Apple is shifting AI server manufacturing and other operations to the U.S. to escape President Trump’s 10% tariff on imports from China. Apple makes many of its iPhones and other tech products in China in partnership with Taiwanese electronics manufacturer Foxconn.

The New York Times says Foxconn will be involved in the Houston factory. Last year, Foxconn spent $33 million to buy 10 acres and a building north of Houston in Harris County, adjacent to one of its warehouses, that it said would be used for its AI server business, according to The Times and Focus Taiwan.

Other countries that produce Apple products include India, Japan, South Korea, Taiwan and Vietnam, according to IndustryWeek.

The Houston plant announcement comes just days after Apple CEO Tim Cook met with Trump at the White House.

“We are bullish on the future of American innovation,” Cook says in a news release, “and we’re proud to build on our long-standing U.S. investments with this $500 billion commitment to our country’s future.”

With establishment of the factory in Houston, Apple will enjoy access to a deep pool of manufacturing workers. As of December, nearly 240,000 people held manufacturing jobs in the Houston area, according to the U.S. Bureau of Labor Statistics. The Greater Houston Partnership says the Houston area is home to over 7,000 manufacturers that produce more than $75 billion worth of goods each year.

Given the region’s solid manufacturing base, Apple should be able to attract plenty of job candidates for its Houston facility.

“Apple’s announcement further solidifies Houston’s leadership as a hub for innovation and advanced manufacturing,” Steve Kean, president and CEO of the Greater Houston Partnership, says in a statement. “This is a testament to our region’s business-friendly environment, skilled workforce, strategic global positioning, and proven ability to attract world-class companies. As U.S. companies continue to onshore their manufacturing operations, we are bullish on Houston’s ability to win big.”

As the use of AI continues to grow, companies like Apple need more computing power. Thus, the company is making servers — housed at an escalating number of data centers — that bolster its Apple Intelligence program. Apple describes the program as a “personal intelligence system that helps users write, express themselves, and get things done.”

Over the next four years, Apple aims to add about 20,000 employees in Houston and other U.S. locations, mostly in AI and machine learning, research and development, silicon engineering, and software development. Aside from Texas, Apple is expanding in Arizona, California, Iowa, Michigan, Nevada, North Carolina, Oregon, and Washington.

In Texas, Apple already maintains a significant presence in Austin, where it employs about 7,000 people at two corporate campuses. Elsewhere in the Austin area, it has offices in West Lake Hills and San Marcos. It also maintains an office in Dallas.

Study proposes converting Houston's vacant office space into affordable micro-apartments

Innovative Living

Downtown Houston has been fortunate to benefit from a transformation over the last couple of decades. Beautiful green spaces, luxury high-rises and hotels, restaurants, and updated arts and entertainment facilities are home to impressive art installations, farmers markets, major professional sporting events, and more. On the flip side of this, Houston’s central business district has seen a steep decline in commercial occupancy, struggling to bounce back to pre-COVID levels.

Houston is not alone in experiencing this situation. Nationwide, commercial vacancies are becoming increasingly noteworthy as the gap between residential rental rates and stagnant wages widens. Low-income earners, folks making between $20,000 and $30,000 annually (typically minimum wage employees, students and seniors living on Social Security), have been joining the ranks of the unhoused at an alarming rate due to the scarcity of affordable housing. Armchair economists and the like have been arguing for years that cities should repurpose these untapped resources into an opportunity to create dignified affordable housing that would keep those at risk off the streets and close to public transit options.

Pew Charitable Trust, along with international architectural firm Gensler, recently released their findings from a study on the subject — with Houston being one of two markets studied. The “Flexible Co-Living Housing Feasibility Study” found that converting Houston’s empty office buildings to communities of micro-apartments is, well, feasible.

“In the current climate of high construction costs, interest rates, building expenses, and rising rents, this project looks at the conventional office-to-residential conversion in a different way by leveraging the existing building infrastructure to reduce costs on a per unit basis,” Brooks Howell, principal architect at Gensler, tells CultureMap. “The result is a new housing typology, a co-living concept, that can provide affordable housing to the large and growing number of lower income single-person households in an urban context.”

The numbers
HUD reported that in 2024 homelessness was at an all-time high of 770,000 persons, up a staggering 18 percent from the prior year. Houston is on the low end of the national average, with a reported 3,270 homeless persons (4/10,000 Houstonians). CoStar data shows that Houston’s central business district contains 88 office buildings of over 50,000 square feet, 19 of which show reported vacancy rates of over 30 percent. As of November 2024, the median rent in Houston for an apartment was $1,297. The proposed rental rate for a furnished micro-apartment in a converted office building in downtown Houston is $700 — all inclusive, with zero move-in costs, as the units are fully furnished.

“The U.S. has a housing shortage of 4-7 million homes, which has driven rents to an all-time high and made it hard to save to buy a home,” Alex Horowitz, a project director for Pew Charitable Trust and a co-author of the study, adds. “Houston has one of the highest office vacancy rates in the U.S., but office layouts often don't work well for apartment conversions and carry high costs. This study finds that converting offices to dorm-style housing is cost-effective and can enable low rents — about $700 per month to live downtown. That could make a real difference for people struggling with high housing costs while revitalizing downtown.”

Co-living explained
Co-living is hardly a new concept. “Single room occupancy” dwellings, or SROs, were extremely common until about 1950. It’s worth noting that during the height of its popularity, homelessness was rare. The co-living model allows for a private furnished space, while bathrooms, kitchens, and laundry are shared facilities — much like a college dormitory. With 40 percent of renters being single occupants, this model promotes socialization and community, something that has been trending downward since the pandemic.

Wesley LaBlanc, principal analytics director for Gensler Chicago, adds that this elevated dorm situation is a “jumping off point for a number of models,” noting that there are six variations from the one in the study. LeBlanc encourages people to “Think beyond the conventional. A whole world of housing solutions come out of this.”

What to expect in a typical converted building
The Pew/Gensler report proposes a prototypical building standard of 24 floors, 19 of which are residential, with 60 micro-apartments per floor, or 1,140 residential units per building. Each floor would offer six shared kitchen areas, five larger shared living spaces, two smaller shared living spaces tucked into interior hallways, two central shower areas with five private shower rooms each. Two shower rooms would include toilets and sinks, plus two additional toilet rooms with four toilets and two sinks. The total comes to 10 showers, 12 toilets, and 14 sinks per floor. Two laundry rooms, each with three washers and dryers, would also be available per floor.

The high cost of converting office buildings into fully plumbed, individual studio apartments can be cost prohibitive, leading a pragmatic Howell to ask: “What if we didn’t demo everything?” The utilization of existing centralized plumbing on each floor saves an average of 25-35 percent in construction costs that would arise from running new plumbing to each unit.

The ground floor would consist of a main lobby, management office, and 10,000 square feet of retail space. Floors two through four would be reserved for parking, while the fifth floor would offer 10,000 square feet of Class B office space as well as amenities like the gym.

While subsidies will be required for the conversion, the same will not be true once the development is out of the construction phase. The co-living model is projected to cost around one-third of the cost of converting an office building to individual studio apartments or constructing new affordable housing.

Micro-apartments details
Each individual unit is designed to be 151 square feet, approximately the size of a modest hotel room. Furnishings include one extra-long twin bed (bedding included), a desk, chair, nightstand, standard-depth half-sized fridge, storage shelf, and cabinet. Units would have solid-core wooden doors and appropriate sound insulation — all for a tidy $700 per month.

Pricing has been a key factor in determining this configuration for affordable, urban housing. “Lowering the cost of housing to manageable levels enables residents to spend more on the other financial needs of their lives, which has broad implications for quality of life and well being,” LeBlanc explains.
