Why is it interesting: Ganiga is selling Hoooly to corporate campuses and shopping centers like airports to increase recycling rates, by providing analytics that help with ESG reporting.

Gemini Energy

What it does: Gemini has developed a gas turbine technology that can generate energy on site, turning natural gas into electricity without burning it, it says.

Why it matters: The company is selling its clean power generator to data centers and says its system could be deployed in the months and years needed to upgrade the local grid.

The world of Helix

What it does: Helix Earth has developed world-class products from the chemistry of jet fuel, including high-performance HVAC and air extraction systems.

Why it matters: The company says its solutions are energy-efficient and cost-effective and can be recycled on commercial roofs.

Power

What it does: HKG Power has developed silicon materials for the next generation of lithium-ion batteries.

Why it matters: HKG says its technology increases battery performance by 80% yet consumes up to 40% less than conventional batteries.

HomeBoost

What it does: HomeBoost offers a self-assessment energy system that helps homeowners identify leaky windows and find opportunities for rebates and other ways to reduce their energy bills.

Why is it interesting: Sends home owners a device that, combined with a smartphone app, analyzes the home and then home energy experts review and issue a report.

HyWatts

What it does: HyWatts offers flexible systems that generate power for industrial applications.

Why it matters: It calls its system Power-Plant-in-a-Box, which combines hydrogen storage with renewable fuel cells for, it says, zero-emission, off-grid electricity at a much lower cost than battery storage.

It’s good

What it does: Kaio Labs produces CO₂ Converting technologies to convert waste carbon dioxide into valuable chemicals such as carbon monoxide, formic acid, and ethylene.

Why it matters: Kaio uses an AI-powered approach to its findings, aiming to extract the drug in a cost-effective way.

MacroCycle Technologies

What it does: MacroCycle has developed technology to recycle polyester fabrics.

Why it matters: The company promises to make recycled plastic as cheap as possible as a virgin material through technology that separates the important synthetic fibers from the dirty fabrics.

Company Profile Namu Robotics Corporation

What it does: Namu Robotics offers tree planting robots for reforestation.

Why it matters: The world lacks the means to quickly replant trees between people and land, so Namu’s technology promises to solve the problem.

Hard

What it does: Naware offers an AI-powered weed killer that attaches itself to lawnmowers to kill weeds when the grass is mowed.

Why it matters: Not only does it detect weeds, it also uses hot steam to kill them, not herbicides.

Secure

What it does: Segura offers a water testing system that provides almost instant results without the need to hire professional testers.

Why it matters: Segura has developed a test line that is reminiscent of what is used to diagnose diabetes and is easy to use.

ShellVive

What it does: ShellVive has developed a water filtration system by recycling oyster shells.

Why it matters: ShellVive’s solutions take a large amount of agricultural waste, such as discarded oyster shells, and turn them into a low-cost, water-friendly filter material.

Whisper Energy

What it does: Whisper Energy is developing an AI sensor to improve energy efficiency in commercial buildings.

Why it matters: The company is targeting small to medium-sized buildings with its easy-to-install sensors and systems as a cost-effective way to replace large-scale energy systems.
