“We are strong believers of leveraging existing infrastructure and expertise to fast track decarbonization goals,” Arpit Dwivedi, founder and, says CEO of Cache Energy. “We look forward to this collaboration and learning from Halliburton's manufacturing and operational expertise, as we scale our technology.”

From Be'er Sheva City in Israel, CENS develops enhanced dry dispersion technology based on dry-treated carbon nanotubes that enable high energy density, high power, and outstanding cycle performance in Li-ion batteries. The technology is differentiated because it can be applied to any type of lithim-ion battery and its implementation can be seamlessly integrated into the production line.

“Our goal is to develop ground-breaking technologies that will become disruptive technologies to market at a massive scale,” says CEO Moshe Johary. “With the help and vast experience of Halliburton Labs' team, we could achieve advancements in production capabilities while extending our footprint in the market.”

Casper, Wyoming-based Disa Technologies provides solutions to the mining and remediation industries. Disa utilizes patented minerals liberation technology to more efficiently isolate target minerals and mitigate environmental impacts to its users. Disa platforms treat a wide array of critical minerals that are essential to the economy and our way of life.

“We are excited to have Halliburton's support as we scale-up our technology and deliver innovative minerals processing solutions that disrupt industry best practices, enhance global resource utilization, and benefit the environment and the communities we serve," Greyson Buckingham, Disa's CEO and president, says.

Marel Power Solutions, headquartered from Michigan, is innovating electrification through its novel powerstack technology. These materials-efficient, quickly deployable, and scalable power-stacks, encapsulating advanced cooling technology, redefine power conversion in mobility, industrial, and renewables spaces.

“We're thrilled to contribute to global climate sustainability. Our collaboration with Halliburton will accelerate the electrification transition across industries. Marel's technology not only maximizes heat evacuation from densely packed power semiconductors but, more importantly, offers substantial savings in cost, weight, size, and time, making it transformative in the evolving landscape of electrification,” Marel CEO Amrit Vivekanand says.

And lastly, XtraLit is an Israeli company that develops a technology for direct lithium extraction from brines. The technology enables efficient and economically justified processing of brines even with relatively low lithium concentrations. Application of the extraction technology will allow mineral providers to unlock new significant sources of lithium that are critical to meet growing demand.

“Oil and gas industry produced waters might become a substantial resource for lithium production,” says XtraLit CEO, Simon Litsyn. “XtraLit will cooperate with Halliburton on optimization of produced water treatment for further increasing the efficiency of the lithium extraction process.”

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."

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.
