Friends, we are thrilled to welcome 20 new companies into the EEx portfolio.
This is our seventh cohort, and it’s bursting with what we call Earthshot ideas — technological and business innovations that have the potential to transform our world for the better. Earthshot ideas are designed to make our communities more resilient and more sustainable. They can pave a path to a future where people thrive and economies prosper, without damaging our planet.
And this year, we gathered a bounty of Earthshot ideas that we can’t wait to share with you.
They come from 20 startups squaring off against the biggest challenges in modernizing our energy, water, mobility, and agriculture systems while ensuring equitable access to clean technology in every community. 20 passionate teams made up of risk-takers, change-makers, and Gordian-knot cutters. 20 Earthshot ideas designed to end our dependence on fossil fuels, assure abundant and safe drinking water, and tackle the mounting crisis of plastic waste. 20 innovations that will shape the future of electric mobility, the circular economy, and much more.
Before we introduce the new companies in this cohort, we wanted to highlight some of the trends we’ve been tracking as we selected this cohort:
👓 The circular economy comes into focus. We’ve witnessed a broad maturation in the companies and technologies that can transform our economy from one that is extractive into one that is fundamentally restorative and regenerative. Some, like BioCellection and Full Cycle Bioplastics, are emerging from significant R&D time and are now primed to make the leap from the lab into commercialization. Others, like Yerdle Recommerce and CarbonCure, are poised for market expansion and growth, where they can significantly shrink the carbon footprint of supply chains and the built environment. As resource scarcity reaches a tipping point and it becomes more economically practical to reuse and recycle materials, we expect this trend will only continue to magnify.
🚀 Electrification of transportation, including aviation, is ready for takeoff. With a high volume of short-haul flights, Hawaii is the perfect testing ground for an electric aviation company like Ampaire. And we are supporting electric mobility companies like Proterra, Scoot, and Chargetrip as they expand outside of their home markets and into new customer segments.
💧 Increasing access to clean, reliable drinking water. While it might not be as eye catching as electric planes and carbon-infused concrete, water scarcity and contamination are growing challenges we are focusing on in regions like California and Australia, where we will be deploying projects with Microvi – which removes nitrate contamination in a low-cost, low-impact way – and Zero Mass Water – which builds solar panels that create drinking water.
🌱 Equitable distribution of clean technology. Our new Equity & Access track is designed to increase access to innovation in low- to moderate-income communities, and is aligned with California’s plan to prioritize LMI communities when allocating funds from its cap-and-trade program. That we saw such strong interest in this track — 42% of this year’s startup applicants applied for it — reinforces our belief that beyond social responsibility, this market presents an attractive business opportunity.
And with that, please take some time to get to know the startups in our seventh cohort, their Earthshot ideas, and why we love them.
Ampaire | MOBILITY
Electric commercial aircraft
Why do we love them? Electrifying the aviation industry can have a massive impact on global carbon emissions — but it’s a massively difficult challenge. In Hawaii, for example, the aviation sector accounts for the highest percentage of petroleum use (32% as of 2016). Ampaire’s approach is to retrofit existing airplanes with batteries, rather than building an entirely new electric airplane from the ground up. Their initial target market is 9-19 seat airplanes, meaning they can be especially beneficial in Hawaii where many short-haul airplanes carry passengers and freight between the islands.
Blue Planet Energy Systems | SOLAR & STORAGE
Safe, powerful energy storage
Why do we love them? As Hawaii’s leading energy storage manufacturing company, Blue Planet Energy Systems has developed safe and reliable battery system for larger-scale microgrid settings.

SparkMeter’s simple, low-cost smart metering solutions are designed to alleviate this energy poverty and make access to electricity possible in hard-to-reach places and underserved markets. The company’s product works in both rural microgrid and existing urban central grid settings, and was created by veterans of microgrid development projects in Haiti.
Sunfolding | SOLAR & STORAGE
Seriously simplified air-driven solar trackers
Why do we love them? Sunfolding’s solar trackers use simple, air-powered components to pivot panels, instead of the mechanical devices found in traditional tracking arrays. And Sunfolding’s easy-to-install, low-maintenance systems can yield 20% greater energy than traditional ground-mounted PV arrays. Sunfolding’s technology allows for greater flexibility in sighting and laying out solar projects, meaning less land (and less maintenance) is needed to produce more energy.
Zero Mass Water | WATER
Making drinking water from sunlight and air
Why do we love them? Zero Mass Water’s product is a category-defining technology that uses the power of the sun to make clean drinking water from the air. The company’s SOURCE Hydropanels require no infrastructure and can efficiently operate across a wide range of climates, particularly where water is scarce. Over a 15-year lifespan, each Hydropanel displaces over 50,000 PET plastic bottles. Our project with Zero Mass Water, in partnership with aboriginal-owned Wilco Electrical, will directly offset the use of over 30 million plastic bottles in Western Australia.
EQUITY & ACCESS
BioCellection | CIRCULAR ECONOMY
Upcycling hard-to-recycle plastic waste
Why do we love them? Outside of climate change, plastics pollution is one of the world’s greatest environmental threats. BioCellection’s technology addresses the problem of hard-to-recycle and unrecyclable plastics, which often end up in landfills or are incinerated in facilities located in or near low- to moderate-income communities. BioCellection’s chemical process has no harmful emissions and diverts this waste by turning dirty plastics and films into biodegradable chemicals.
BlocPower | GRID & EFFICIENCY
Machine learning and structured finance to green inner cities
Why do we love them? Older buildings found in inner cities and financially underserved communities are often the ones that could benefit the most from energy efficiency upgrades. But financial constraints can make it difficult to secure clean energy retrofits for them. BlocPower collects and analyzes data from buildings (such as community centers, churches, and multifamily residences) to identify which have the most potential for energy savings. By grouping these buildings into “blocs,” BlocPower can help dilute risk and secure investments for new clean energy projects.
Microvi Biotech | WATER
Biotechnologies for safe drinking water, wastewater treatment, and renewable chemicals
Why do we love them? Nitrate is the most prevalent groundwater contaminant in the world. Microvi has developed a biological technology — made up of naturally occurring, high-performing organisms — that removes this common and harmful pollutant by completely degrading it into harmless nitrogen gas with no biological waste. Microvi is committed to installing affordable, modular, turnkey treatment systems in disadvantaged agricultural regions where nitrate contamination is overwhelming the drinking water supply.
Scoot Networks | MOBILITY

EthosGen | GRID & EFFICIENCY
Transforming waste heat into resilient and reliable energy
Why do we love them? EthosGen brings energy efficiency and generation to previously untapped locations such as manufacturing, pharmaceutical companies, food processors, and other industrial businesses. Its hardware device, which can be installed in unused or underutilized floor spaces, captures low-grade waste heat from equipment — like air conditioning units or machinery with a compressor or motor — and converts it into electrical power or cooling capacity. That means businesses can generate on-site, renewable, and resilient energy from their existing industrial processes.
FlyWire Cameras | FOOD & AG
Electronic monitoring for sustainable fisheries
Why do we love them? Many small fisheries face a conundrum in verifying that their fish is sustainably caught (which can add a 20% premium to its price). Keeping observers on board your vessel can be logistically difficult, expensive, and dangerous, while the monitoring systems used by commercial fishing fleets are both expensive and too large for smaller boats. FlyWire Cameras’ HD video-based monitoring system provides high-quality data collection around catch composition at a tenth of the cost of existing monitoring systems.
Full Cycle Bioplastics | CIRCULAR ECONOMY
Converting organic waste into compostable bioplastic
Why do we love them? We love companies that tackle climate change and companies that tackle food waste. So we adore Full Cycle Bioplastics for tackling both at the same time. Full Cycle’s technology produces a fully compostable, marine-degradable bioplastic polymer out of mixed organic waste (one of the largest man-made generators of greenhouse gas emissions), such as inedible food waste, agricultural by-products or cardboard. And it’s a fully closed-loop solution: once it has served its purpose, the bioplastic product can either biodegrade or be upcycled back into bioplastic polymers for another product.
Imprint Energy | SOLAR & STORAGE
