Armed with a fresh $3 million round of seed funding, Los Altos, California-based Universal Fuel Technologies is establishing a lab in Houston for production of sustainable aviation fuel samples.

TO VC led the round, with participation from Alchemist Accelerator, Claire Technologies, and World Star Aviation.

Unifuel’s Flexiforming technology consists of a series of chemical reactions that convert various sustainable materials — such as ethanol, methanol, and liquified petroleum gas — into high-quality SAF that’s similar in chemical composition to traditional jet fuel. Continue reading.

Occidental Petroleum’s carbon capture, utilization, and sequestration (CCUS) subsidiary has tapped another Houston-based company to develop a carbon dioxide pipeline and transportation network for one of its CCUS hubs.

Under its deal with Occidental, pipeline company Enterprise Products Partners will create a carbon dioxide pipeline system for 1PointFive’s Bluebonnet Sequestration Hub, which will span more than 55,000 acres in Chambers, Liberty, and Jefferson counties. The hub will be able to hold about 1.2 billion metric tons of carbon dioxide. The new pipeline network will be co-located with existing pipelines. Continue reading.

Switching from a gas-powered car to an electric one can be a big change, but a Houston-based company has made things a lot easier for its customers.

Octopus Electric Vehicles US, a spinout of United Kingdom-based retail energy provider Octopus Energy, matches its users with their perfect EV lease and sets them up with smart electricity technology for at-home charging.

"We do a couple of really unique things that are not only first of its kind but really innovative," Octopus EV's US Co-Lead Chris George says on the Houston Innovators Podcast, pointing out specifically Octopus Energy's Intelligent Octopus, a smart feature for customers that automates energy usage to lower cost.

"We launched an Intelligent Octopus for EVs service. Instead of operating in a very narrow window — overnight — it operates dynamically," he continues. Continue reading.

Houston tech company expands platform to include renewable certificates

A Houston-based energy trading risk management software company announced enhancements to its platform that will simplify the process of managing and allocating renewable energy certificates — a tool to help to meet demand obligations.

Molecule Software made these new enhancements to its product, called Hive, to enable its clients to manage their energy portfolio and renewable credits together in one scalable platform. With Hive, users simplify massive data stacks and reduce manual workloads while preventing errors.

“Renewables are still a new frontier, and one of the biggest challenges we’ve seen is modeling all their nuances in a way that makes sense for informing retirement and predicting the market,” says Sameer Soleja, founder and CEO of Molecule, in a news release. “Another major challenge is the sheer volume of data associated with modeling certificates and their individual serial numbers.” Continue reading.

A View From HETI

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
