A case for public funding that accelerates climate tech and pays off.

One of the biggest hurdles clean energy entrepreneurs face is bridging the “valley of death” between promising technology and a market-ready product. Since 2019, New Energy Nexus’s CalTestBed Initiative has tackled that challenge head-on (thanks to a $22M investment made through the EPIC program by the California Energy Commission).

By offering startups vouchers for third-party testing at world-class facilities, CalTestBed helped 63 companies validate their technology, gain investor trust, and accelerate their path toward commercialization. The return?

A 19.9x multiplier:

• $22M in testing support led to
• $438M in follow-on funding
• 300+ jobs created

Why it works: Trusted testing builds investor confidence

Startups received up to $300,000 each in testing vouchers, redeemable at over 70 labs across Lawrence Berkeley National Lab and nine UC campuses. This provided them with access to rigorous, independent validation – exactly what investors and customers need to mitigate the risks associated with early-stage technologies.

And the benefits went beyond funding.

58% of companies that completed testing reported TRL advancement; on average, their Technology Readiness Level (TRL) increased by 2.1

Several jumped from prototype to market-ready

“We went from TRL 6 to 9,” said a representative from Delphire Inc., a grid tech company. “That shift helped us unlock market access and investor interest.”

Innovation in action: real-world success stories

The companies that came through CalTestBed aren’t just testing, they’re scaling:

• Community Energy Labs is helping over 20 school districts reduce their energy bills with smart building controls.
• EH Group signed a deal to develop hydrogen fuel cell drivetrains for maritime shipping.
• Enzinc opened a 10,000 sq. ft. plant in Oakland to scale zinc batteries—a safer, more sustainable alternative to lithium-ion batteries.
• Gridware partnered with S&C Electric to launch a grid resilience solution.
• ReJoule, an award-winning startup, enables EV battery reuse, building the circular economy for clean transportation.

Why Californians should care

The impact of CalTestBed goes beyond investor returns. For ratepayers, it means:

• More reliable energy from proven, efficient tech
• Lower bills from faster deployment of cost-saving innovations
• Safer systems through standardized testing
• A stronger economy from job creation and homegrown climate solutions

A smart bet on the future

CalTestBed, funded by the California Energy Commission’s EPIC program and administered by New Energy Nexus, is a model of how modest public investment of $22M, can unlock climate, economic, and equity wins. As the current funding cycle concludes in 2025, one thing is clear: this model works. It bridges the innovation gap, supports diverse entrepreneurs, and delivers value to investors and the public.

The clean energy transition is our chance to build a fairer future, yet women are still missing from the table. Around the world, only 15% of clean energy leadership roles are held by women.

Even in Thailand, a leader in the Asia Pacific region when it comes to women’s leadership in the energy sector, women occupy just 23% of leadership positions.

But when women are at the helm, the impact speaks for itself.

Salinee Hurley is proof that inclusive leadership powers inclusive solutions. A mechanical engineer specializing in solar, she founded SunSawang: a social enterprise bringing solar home systems and lanterns to off-grid villages along the Thailand–Myanmar border. She is also the Project Director at the Border Green Energy Team (BGET), an organization advancing clean energy access in the region.

Salinee’s journey into solar began when she pursued further studies in solar engineering in the United States. Returning to Thailand, she initially implemented solar projects through an NGO model, using grant funding to provide free installations in remote areas. Over time, she realized the approach lacked long-term sustainability.

To address this, Salinee transitioned to a social enterprise model, offering long-term payment plans that support both ongoing maintenance and local ownership.

“Free installations may help in the short term, but the real goal is to empower people to access energy independently in the long run,” she said.

SunSawang now trains and hires local technicians and sales agents to serve their own communities. This localized model not only keeps systems functioning, but also supports economic activity—access to reliable electricity allows for evening work like weaving, increasing household income.

Salinee’s work also highlights the systemic barriers that persist in Thailand’s solar landscape: high upfront costs, inconsistent regional regulations, and limited financing options for low-income households. Recent steps, including draft laws to simplify rooftop solar permitting and new green loan products, are promising, but access remains uneven.

Last year, she joined New Energy Nexus Thailand’s SolarSTEP initiative, where she shared her expertise and connected with other women leading the shift to a cleaner energy future.

Supporting women leading the way

SolarSTEP is designed to build skills and leadership among solar technicians and entrepreneurs, with a focus on women, to help accelerate Thailand’s clean energy transition.

This work is spurred on by Thailand’s ambitious target to reach 12,139 MW of solar capacity by 2037, as outlined in its Alternative Energy Development Plan (AEDP). Hitting this target will take more than policy; it requires investing in people, empowering women, and expanding access to rooftop solar across the country.

This is where SolarSTEP comes in. The program has already delivered seven trainings across Thailand’s Central, Northern, and Southern regions, reaching over 200 participants. These efforts have been strengthened through collaboration with key partners, including PEA Encom Smart Solution, PEA Encom International, and LONGi.

Looking ahead, we’re focused on scaling impact, broadening solar access, and building a sector that mirrors the diversity of the communities it serves.

If we want a just and resilient clean energy future, we need to break down the barriers that keep women on the sidelines and back those already leading the way. Empowering more women to participate and lead in clean energy isn’t just the right thing to do—it’s the smart thing to do.

Australia is charging ahead in the race to build a battery-powered world—and the timing couldn’t be better.

The nation’s growing role in the global battery supply chain took center stage at our recent webinar, Australia’s Time to Charge: Powering the Battery Future. The hour-long session, part of our Just Batteries initiative, explored how battery innovation, mass EV retrofitting, and smart policy could transform Australia into a clean energy powerhouse.

These industry experts led the discussion, held virtually on June 19, 2025:

• Kirk McDonald, Project Manager- Supercharge Australia, New Energy Nexus
• Andrew Chang, Chief Growth Officer, New Energy Nexus
• Kyle Van Berendonck, Founder, Veepower
• Derick Gyabeng, Program Lead – Supercharge Australia, EnergyLab

Why this conversation matters

The battery supply chain is the backbone of the energy transition, and Australia’s unique mix of critical minerals, renewable energy resources, supportive policies, and skilled workforce positions it to lead the way.

This is what we’re backing through Supercharge Australia, a collaboration between New Energy Nexus and EnergyLab. The program aims to support 150+ local startups, empowering them with mentorship, funding pathways, and global connections to expand Australia’s lithium battery value chain.

6 key insights from the webinar

1. Australia’s global opportunity is now

Australia is well-positioned to become a significant player in the battery-powered electrical transformation. Here’s why:

There are signals from state and federal governments that they want to move away from a fossil fuel-based export economy, such as:

• Signing an agreement with 40 other countries at COP28 to phase out offshore support for coal, oil, and gas projects;
• Passing the Future Made in Australia policy, which committed AU$22.7 billion over 10 years to build domestic capacity in green hydrogen, solar panel manufacturing, critical minerals processing, green metals, low‑carbon liquid fuels, and clean-energy manufacturing;
• Australia could be a leader in homegrown battery manufacturing, and critical minerals refining and processing; and,
• It’s building on a “globally competitive” battery export industry. Queensland alone is investing hundreds of millions into a sector that it believes will be worth US$1.3 billion by 2030, and can create up to 9,100 green jobs.

2. Mass EV retrofits could boost battery demand 20-fold

Retrofitting existing vehicles—especially commercial fleets—is a faster, cheaper, and lower-carbon way to scale EV adoption. Our second Supercharge Australia Innovation Challenge spotlighted 12 startups electrifying everything from mining trucks to boats.

The current projection of a 65GWh demand for stationary storage by 2030 could be massively higher with mass EV retrofits. Multiplying Australia’s vehicles by their estimated battery capacity, turning half of Australia’s vehicle fleet into EVs could multiply local battery demand 20-fold to over 1.3TWh, enough to justify domestic cell production and build a full onshore value chain (more here).

3. Startups like Veepower are leading the way

Kyle Van Berendonck, founder of Veepower and Retrofit Nation challenge winner, introduced Veepilot: a drop-in EV brain that lets large garages and re-manufacturers, through to individual garages, convert vehicles to electric with professional and supportable software — a key concern of retrofit solutions.

After a tour of California’s thriving clean energy ecosystem with New Energy Nexus, Veepower is now raising AU$500K from climate-focused investors to scale in Australia.

4. Smart policy can unlock big impact

The discussion emphasized the need for policies to support battery retrofits, including:

• Support the emerging startup practitioners with ambitious non-dilutive government grant funding
• Launch an AU$100–200M finance facility for training to upskill workers and kit production for vehicle upgrade
• Establish mass EV retrofit precincts, particularly in regional Australia
• Prioritize public fleet conversions to seed early demand

These interventions could support thousands of upskilled ICE workers (such as mechanics and automotive electricians) and create a more circular, cost-effective battery and transportation economy.

5. Startup support is critical

Through tailored workshops, mentorship, and investor-readiness training, the Supercharge Australia Incubator aims to help founders bridge key gaps in prototyping, lab access, and commercialization. As Kirk McDonald and EnergyLab project lead Derick Gyabeng said in the webinar, early-stage startups need consistent, generous support to grow from an idea to an investment-ready solution.

Moreover, Supercharge Australia is leading a push to bring learnings from California’s best practice startup testing program, CalTestBed, to Australia. As part of the CalSEED-CalTestBed pair offering US$1M in non-matching and non-dilutive support to founders, startups can receive vouchers up to US$300K in value to use at the University of California and National Labs testing facilities across the state.

CalTestBed has supported over 150 startups with $45M in vouchers, with over 40% being received by women and under-represented founders.

6. Australia’s Leadership Can Power the Region

The country’s battery innovation doesn’t stop at its borders. With Southeast Asia on the path to rapid electrification, Australia’s EV retrofitting industry can serve a region set to reach 770 million people by 2050.

Supporting Australia’s battery supply chain at this stage could play a huge role in the region’s clean energy transition.

Why ‘Just Batteries’

Batteries are the linchpin of the clean energy transition. But how we build this industry matters as much as how fast we scale it.

At New Energy Nexus, we believe battery innovation must be just, inclusive, and community-led. Today, the battery supply chain is dominated by a few countries and companies, with little accountability to communities, workers, or the environment. Battery recycling and reuse are underinvested solutions. And left unchecked, the race for minerals and manufacturing could replicate the injustices of the fossil fuel era.

This is what our Just Batteries initiative addresses. We have supported 116 startups across the battery value chain—from extraction to recycling—while shaping an innovation ecosystem rooted in equity, access, and sustainability.

Our work spans the full ecosystem, from startup accelerators and testbeds to international market access, because building a clean energy future means backing entrepreneurs at every stage.

Join us, invest in these startups, and let’s supercharge the transition in Australia and beyond. Check out how you can support this initiative and more here.

By Julius Mujuni, Country Director – New Energy Nexus Uganda

I recently had the privilege of engaging with Otto Scharmer, a global thought leader in systems change. His call to adopt a systems thinking approach was a timely reminder of the complex and interconnected nature of energy access in Africa—and a rallying call to those of us working to address it.

For decades, a persistent and troubling figure has hovered over the sector: over 600 million people across Africa still live without access to electricity. We’ve seen incredible innovation—yet the challenge remains immense and deeply systemic.

Decades of innovation are laying the foundation

At New Energy Nexus Uganda, we have worked hard to meet this challenge. Over the past decade, models like Pay-As-You-Go (PAYGO) have enabled households to access solar technologies for the first time, especially in off-grid rural communities.

In rural Masindi District of Western Uganda, where access to electricity is very limited, a woman holds a solar panel that lights her home.

We’ve seen the catalytic role of micro finance institutions, helping families overcome high upfront costs. And through our own Results-Based Financing (RBF) program, we’ve delivered targeted support to Community-Based Organizations (CBOs) and Village Savings and Loan Associations (VSLAs)—trusted local actors uniquely positioned to drive last-mile distribution.

This approach is working:

• In 2023 alone, 19,200 people were connected with clean energy products and 1,117 green jobs were created.
• We’ve supported 654 entrepreneurs, 33% of whom are women.
• We partnered with over 200 CBOs and VSLAs, expanding access to solar lighting, clean cookstoves, water filters, and briquettes​.

Why a systems lens matters

Otto’s insight reminded me that energy access isn’t an isolated issue—it’s intimately tied to income, resilience, and opportunity. Even when the grid reaches rural areas, low-income families often can’t afford electricity or use it productively.

So what if we centered productive use of energy—clean energy that directly powers livelihoods? What if access to Productive Use of Renewable Energy (PUE) technologies is the answer to low income earners getting sustainable access to other off-grid energy products? What if access to PUE technologies enables increased access to health services and other health related products?

The PURE program: Energy for income and impact

That’s what we’re testing through our PURE (Productive Use of Renewable Energy) initiative. This program is designed to empower rural entrepreneurs and farmers with income-generating, solar-powered assets like irrigation systems to increase agricultural output, milling machines to process produce locally, and other small-scale tools that can boost productivity.

We believe this approach can create a self-reinforcing cycle: energy drives income, income drives further adoption of other off-grid technologies up the energy ladder, and communities become more economically and environmentally resilient.

Community success stories: What’s already working

Take Utopia, a faith-based organization in western Uganda. With support from New Energy Nexus, they’ve:

• Brought clean energy products to over 9,800 people
• Launched an eco-tourism hub that distributes clean energy to surrounding communities​

Or look at KISE (Kitara Community Seed for Transformation) in Hoima, which has delivered clean tech to over 1,000 households and helped families redirect energy savings toward education and health​.

These are not just stories of technology distribution. They are case studies in systems change—where energy is an enabler, not the end goal.

A call to donors and funders: Help us go further

We know that unlocking Uganda’s clean energy future requires more than hardware. It requires patient, flexible capital, support for local leadership, and the willingness to fund models that may look different—but deliver a deeper, longer-term impact that leads to the growth of rural economies to tackle poverty, job creation, and inequality.

As we continue to gather evidence from our PURE pilots and deepen our partnerships with community led groups like CBOs and farmer groups, we invite funders and partners to join us in this journey. A journey that will enable us to create a business case for farmer groups and other entrepreneurs in off-grid communities to thrive and prosper as a result of running sustainable enterprises that use energy productively.

Let’s build an energy system that not only connects wires—but connects people to opportunity. Let’s go beyond access—toward income, equity, and resilience.

The clean energy transition isn’t just happening in labs or boardrooms—it’s also being built on university campuses across the Philippines. At the heart of this movement are Technology Business Incubators (TBIs), which help entrepreneurs turn bold ideas into real-world solutions.

That’s why New Energy Nexus Philippines, together with UMWAD Consortium, DOST Region 6, Iloilo Science and Technology University (ISAT U), and Innovate Iloilo, recently hosted an Energy Incubation Program Training for university TBIs in Region 6. This hands-on training brought together 11 universities and institutions* from across the Visayas to build the skills, partnerships, and strategies needed to launch the next generation of climate-tech and clean energy startups.

Here’s what we learned—and why it matters.

1. 🚀 Energy innovation needs a boost from campus to market
From solar-powered aquaculture to digital energy audits, university teams in the Visayas are brimming with ideas. But many clean energy startups still struggle with business models and go-to-market strategies. TBIs are stepping up to fill this gap—but they need more support to guide founders from research to revenue.

2. 🔍 Manual energy audits are holding back progress
Several universities highlighted how energy auditing is still done manually—a time-consuming and inefficient process. Digitizing these audits presents a major opportunity for startups and researchers to develop tech-based solutions that can scale across the region.

3. 📚 Clean energy is sparking curiosity in classrooms
Interest in energy innovation is growing among students and faculty alike. At schools like the Iloilo State University of Fisheries Science and Technology, clean energy topics—from IoT to smart grids—are becoming central to research and student projects. That’s a strong sign of a rising talent pipeline.

4. 🏛️ Stronger university integration = stronger incubation
To thrive, TBIs need to be embedded into the fabric of the university—not siloed from students, researchers, or decision-makers. Active outreach and curriculum alignment can help make energy entrepreneurship a core part of the academic journey.

5. 🤝 Co-incubation is the way forward
NEX Philippines is inviting TBIs to co-incubate energy startups with us—combining resources, networks, and expertise. It’s a powerful model for supporting startups that are tackling the region’s biggest energy challenges. (This reflects NEX’s global strategy of ecosystem collaboration.)

6. 💸 Funding and experts are make-or-break for TBIs
TBIs need more than just enthusiasm. Sustained operations require access to technical experts, funding sources, and proven business models. Without this, even the most promising ideas risk stalling out before they leave the lab.

7. 🎓 Energy entrepreneurship needs to be taught
TBIs are exploring how to integrate clean energy into research, extension programs, and classroom instruction. Building climate-tech capacity isn’t just about startup competitions—it’s about transforming the entire education system to prepare innovators for the real world.

What’s Next for Region 6?

This training is just the beginning. NEX Philippines is already planning:

• Follow-up workshops on energy trends, startup mentorship, and sustainable business modeling
• Demo days and showcases to spotlight regional clean energy innovations
• Curriculum development aligned with energy entrepreneurship
• Ecosystem-building efforts that connect universities with funders, government, and private sector partners

Behind every climate-tech startup is an ecosystem that helped make it happen. And as this training showed, Region 6 is full of institutions ready to lead.

NEX Philippines is proud to support this momentum—and we’re just getting started. Find out more about our work in the Philippines!
