Giang Hoang represents HKG Energy at a 2024 AIS4EE event.

When we first met Giang Hoang, she wasn’t just leading a startup – she was building one from the ground up.

Giang is the CEO and co-founder of HKG Energy, one of New Energy Nexus Vietnam’s corporate partners, which hosted interns through our NEXGen 2024 and Youth Internship Pilot 2025 programs. But even as she helped give young innovators hands-on experience in the country’s fast-growing clean energy, she was still in the process of learning herself; particularly on how to find success in one of the most challenging corners of climate tech.

Giang launched HKG Energy on International Women’s Day, March 8, 2024, and it proved to be more than a coincidence. Working in tech, an industry where women hold only a quarter of CEO positions globally, she has faced her fair share of challenges.

“Being a founder is hard, especially in deep tech,” she said. “In my first three months, most people told me I’d quit within a year. No one trusts you until you deliver. But while some of those voices have since been laid off in today’s tough job market, we’re still here, growing and gaining traction.”

Faster charging, better EVs

HKG Energy’s core innovation, Terra Silicon, is a patent-pending nanomaterial that increases battery energy density by up to 80%, helping electric vehicles drive farther, charge faster, and cost less. Beyond mobility, the technology can improve energy storage systems, consumer electronics, and even robotics, expanding access to cleaner, more efficient power.

Since its founding less than two years ago, HKG Energy has moved fast: entering proof-of-concept phases with global OEMs and battery makers, securing millions in LOIs, and receiving clean energy grants from both Vietnam and the US. Moreover, they’re now a member of Greentown Labs, a leading climate incubator based in Boston.

But her journey didn’t start in America. Giang’s career began in Vietnam, working her way up toward a leadership position in the Vietnamese EV company VinFast and managing a US$2-billion supply chain.

Now, through HKG Energy’s partnership with New Energy Nexus Vietnam, Giang is paying it forward by opening doors for young people to enter the clean energy sector.

“We’re truly grateful for [New Energy Nexus Vietnam]’s commitment to building a sustainable startup and talent ecosystem. Your support goes beyond programs; it’s a belief in the potential of founders and future leaders.”

Vietnam on the rise

For Giang, success isn’t just about building a company; it’s about building capacity for a nation ready to lead in deep tech.

“Vietnam has a unique window to leap ahead, not just as Southeast Asia’s gateway, but as a global hub for deep-tech manufacturing. The key is not waiting for the ecosystem to mature, but actively building it: invest early in high-quality startups, fund national labs and pilot lines, and de-risk commercialization. It’s not a burden, it’s an opportunity to lead.”

Her vision for Vietnam’s role in the clean energy transition is bold, drawing from her experience managing a US$2 billion supply chain for Vietnamese EV company VinFast.

“From my time at VinFast… I saw Vietnam’s speed and scale. But to lead globally, we must shift from assembly to deep-tech leadership. HKG Energy brings that shift – building homegrown IP and advanced battery materials that can power Vietnam’s rise in the global battery value chain.”

Giang Hoang presents HKG Energy to Julien Guerrier, European Union Ambassador to Vietnam.

Giang’s story goes beyond her success in her tech. She is one of many women and Southeast Asian leaders breaking glass ceilings across the globe. As they do this, more innovators can bring forth solutions that can make the clean energy transition go faster – ensuring a better, more sustainable future for everyone.

“Clean energy isn’t just necessary for the planet, it’s a sound investment. It’s already cheaper than fossil fuels and will define the future of industry. For the next generation, stepping into this space isn’t just a mission – it’s a smart, strategic move.”

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.

On International Women’s Day, we celebrate the impact women entrepreneurs have on the clean energy transition, overcoming systemic challenges and biases around the world.

—

Clean energy solutions – the very ones that can help address the impacts of climate change – should not be held back by systemic barriers. Yet women entrepreneurs continue to face disproportionate challenges in funding and scaling their clean energy businesses. In fact, only 3% of global venture capital goes to companies founded solely by women, and just 15% of investors in the clean energy space are women.

These data are not just mere numbers on equitable representation: they speak about missed economic and societal potential. For example, the International Monetary Fund states that only 6% of women in advanced economies hold green jobs, whereas more than 20% of employed men work in this sector. The share of women in green jobs is even lower in emerging markets and developing economies.

Tackling this gender gap is crucial for both economic growth and environmental sustainability. According to the IMF, nations with a higher proportion of STEM-educated workers and robust gender equity policies tend to experience greater reductions in greenhouse gas emissions when implementing climate policies. In the countries where NEX works, we see daily that women are developing groundbreaking clean energy solutions, yet they often struggle to access the same resources, visibility, and agency as their male counterparts.

On International Women’s Day, it’s not enough to simply celebrate women founders for the sake of diversity—we must recognize their ingenuity, resilience, and the transformative impact they’re making in the clean energy sector. These entrepreneurs aren’t just numbers on an inclusion story; they’re building tangible clean energy solutions that reflect the needs of their communities.

The question is, how can they break these barriers and scale their solutions?

What we’re doing

At New Energy Nexus, we’re committed to partnering with women-led startups and businesses, and facilitating access to the resources they need to grow. In 2023, we backed 1,100 women entrepreneurs—40% of the total founders we supported—toward the goal of building a more inclusive clean energy sector. This is far from parity but a huge step in the right direction.

Through our global network, we connect women entrepreneurs not only to capital and mentorship but also to a community of fellow women founders. We provide funding through New Energy Nexus Ventures and partnerships with alternative financing vehicles worldwide while offering training and mentorship through our accelerator and incubator programs across multiple countries.

Women leading the way

This support only elevates the already impactful work these women entrepreneurs are doing. From energy efficiency solutions to improving energy access in off-grid communities, women have their fingerprints all over the global clean energy sector. Here are a few examples across the world:

Community Energy Labs (California, USA)

Community Energy Labs (CEL) is pioneering a low-cost, grid-interactive building control platform that autonomously optimizes energy use, pricing, and comfort. Their innovative solution minimizes the setup and maintenance burden for controls professionals and building operators, making it ideal for K-12 schools, municipalities, and small to mid-sized buildings.

At the helm of CEL is Tanya Barham, a visionary entrepreneur and CEO who is revolutionizing energy management through community-driven, sustainable solutions. With a deep passion for technology and sustainability, Tanya has established CEL as a leader in smart energy systems, empowering communities to reduce costs, lower carbon footprints, and optimize energy efficiency.

Beyond her technical expertise, Tanya is a dedicated advocate for diversity and inclusion in STEM and entrepreneurship

“CalSEED has really enabled our customer focus in a way that I think a lot of technology and R&D organizations don’t necessarily do. So we’ve appreciated that a lot. Also just good people. They’re really just trying to enable you to give you the resources to the network, the opportunities, the visibility to allow you to test your new idea and to allow it to flourish,” said Tanya Barham.

Solar Run Energy (China)

Solar Run Energy is not only a thriving business but also a lifeline for off-grid communities in several countries in Africa, providing solar-powered solutions to millions without electricity.

Founder Xia (Susan) Li grew up in rural China, where she relied on kerosene lamps for light. That firsthand experience shaped her understanding of energy poverty and reinforced her commitment to creating sustainable solutions.

“Today, many girls still have to give up the opportunity to study because they have to fetch water during the day,” Li said. “If there is a light at night, at least they still have a chance to study and read.”

New Energy Nexus China has supported Solar Run Energy, helping scale its impact with access to networks and international markets.

Agrivijay (India)

Co-founded by Shobha Chanchlani, Agrivijay is India’s first curated marketplace for renewable energy products, specifically for farmers and rural households. They have multiple ‘Renewable Energy Stores’ that act as a one-stop shop for solar, biogas, thermal, wind, and electric products.

An alumni of the Women in Energy program we run with Climate Collective, which support the growth of women-led early-stage startups in India, Agrivijay has since established 11 new Renewable Energy Stores and has expanded in the states of Telangana and Andhra Pradesh.

“We’re honored and glad to be part of [New Energy Nexus’] accelerator program, which has helped shape us as an organization with a vision to empower farmers and rural households to fight climate change,” said Chanchlani.

Magi Farm (Indonesia)

The island of Bali in Indonesia has a waste problem, with a large component being food scraps. Led by Indonesian entrepreneur Ima Rida, Magi Farm uses Black Soldier Fly larvae to transform food waste into nutrient-rich compost.

This method not only cuts harmful methane emissions, but also regenerates the environment and opens up possibilities for sustainable tourism.

Magi Farm launched its pioneering, community-focused pilot project with support and a grant from NEX Indonesia.

“Maybe there are Balinese women out there feeling the way I did when I started building my business,” Rida said. “Sometimes the challenge lies in societal expectations: balancing running a business, finding personal time, and participating in traditional community activities.”

GAIA Corp (Philippines)

Women-led startup GAIA Corp is tackling the challenge of heat management in buildings—a critical issue in the Philippines, where rising temperatures are driving up cooling-related energy consumption.

Their insulation technology, The CoolRoof Project, reduces heat absorption in buildings, improving resilience while cutting energy costs.

Operating in a male-dominated industry, founder Eva Lisa Adoremos has faced challenges working primarily with engineers. She overcame this by continuously expanding her expertise through education.

Eva and GAIA Corp are alumni of NEX Philippines’ Startup Acceleration Program, where she gained valuable insights into the administrative side of running a clean energy startup and joined a global network of industry peers.

“I think my role, being a woman in this space, is to become an instrument of promoting equal opportunities for other women who want to be part of this sector,” Adoremos said.

PAC Corporation (Thailand)

Just a short flight away from the Philippines, Thailand also experiences bouts of extreme heat, partly quelled by air conditioning units. However, emissions from these units contribute to climate change, creating a cycle of rising temperatures and increased energy demand.

PAC Corporation is tackling this issue by producing energy-efficient air conditioning units and water heaters that recycle waste heat, reducing both energy costs and environmental impact.

Founder and CEO Atchara Poomee is also a strong advocate for gender equality, mentoring entrepreneurs of all genders and using her platform to inspire more women to enter the sector.

“I would like them to believe that they are capable, and, regardless of gender, we can succeed if we are determined,” she shared in a UN Women article.

Through NEX Thailand’s Decarbonizing Thailand Sandbox, PAC Corporation was matched with corporate partner B. Grimm, helping scale its solutions for a more sustainable future.

Uganda – Local Organizations and Entrepreneurs

With 60 percent of the population still lacking access to electricity, our Uganda program focuses on supporting local organizations that understand the unique challenges of off-grid communities. We’ve provided funding to groups like Utopia, a faith-based organization empowering rural women entrepreneurs to build clean energy businesses in the Kyenjojo district.

A majority of the entrepreneurs we’re supporting in the country are women, and 70 percent of the jobs created by our programs were taken by women as well.

One such entrepreneur is Kizia Janet, whose solar lantern and panel business is now thriving. Beyond securing a steady income, she is helping her community transition to sustainable energy, improving both quality of life and local economic growth.

Wiibike (Vietnam)

Nguyễn Thị Thu Hằng founded Wiibike, Vietnam’s first locally made e-bike, to promote both a healthier lifestyle and a shift toward green transportation.

Her journey began as a new mother concerned about air pollution’s impact on her child’s future. What started as a personal mission has grown into a thriving business, with over 1,000 e-bikes sold and an ambitious goal of reaching 2 million units by 2030. Hằng even pitched Wiibike on Shark Tank Vietnam, showcasing the potential of sustainable mobility.

Wiibike participated in New Energy Nexus Vietnam’s Cohort 2 program, where the team refined their business model, gained insights into fundraising, and built strategic partnerships to scale their impact.

A Vietnamese farmer cuts rice and harvests rice in the Mekong Delta.

Climate change is having a huge impact in Vietnam’s Mekong Delta. The region is sinking 1.1 centimeters every year, and farmers are struggling with inconsistent weather cycles.

In response, its agricultural sector is embracing climate adaptation, powered by brilliant women entrepreneurs whose products are helping the region build resilience.

Through the Deltaccelerate program, funded by the Australian Government and managed by New Energy Nexus, six women entrepreneurs with climate-adaptive products received up to VND 1 billion (over US$39,000) to scale their businesses and strengthen their sustainable practices. These entrepreneurs were selected out of 14 competitive participants, all of whom underwent tailored training and gained networking opportunities.

This program follows a positive trend for diversity in the country’s private sector. Women now own over 20 percent of small- and medium-sized enterprises (SMEs) in the country. As they rise in numbers, so does their role in shaping the future of sustainable business in Vietnam.

Whether they’re using coffee to make mugs, or cat houses from water hyacinth, here are the women-led businesses at the forefront of climate innovation in the Mekong Delta:

Mekong Coconut Oil Company Limited (Cocovie)

Founded by Hoang Thanh Thuy, the company produces quality cosmetic and food products made from coconut oil in the Ben Tre province. They have been utilizing and preserving over 10,000 hectares of coconut trees, estimated to have absorbed 75,000 tons of CO2.

Cau Ke Macapuno Coconut Processing Co., Ltd (VICOSAP)

Lam Ngoc Tu’s business uses macapuno coconuts to produce confectionery, baking ingredients and drinks. Cultivated by the Khmer community of Tra Vinh province, macapuno coconuts are known for their high saline tolerance—making them an ideal climate-adaptive crop.

Palmania JSC

Co-founded by Chau Ngoc Diu, the company produces Palmania, an organic sugar substitute made of sweet nectar from palmyra trees in An Giang province. The business provides jobs to indigenous farmers and taps palmyra trees in a way that does not shorten the trees’ 100-year lifespan.

AirXCarbon/Veritas Vietnam JSC

Represented by Chief Strategic Officer Tran Thanh Thao, AirXCarbon turns materials such as coffee grounds, rice, and coconut husks into bioplastics, used to make zero-carbon products ranging from mugs to alternative packaging.

Dam Doi Sesarmid Cooperative

Tran Thi Xa’s business produces a wide range of sustainable products made from sesarmids and shrimps caught in the Ca Mau province.

Ecoka JSC

Led by Quang Chan Chan, this company manufactures and distributes handicrafts made entirely from natural materials in the Ha Giang province—including water hyacinth, bulrush, rattan, bamboo, and macrame. Their products include bags, coasters, and even cat houses.

About Deltaccelerate

Deltaccelerate is made possible by a unique partnership between the Australian Government and New Energy Nexus through the Business Partnerships Platform (BPP) Climate Adaptation Partnerships in the Mekong Delta, announced in November 2023.

Deltaccelerate is a business accelerator funded by the Australian Government providing direct support, tailored training, and networking opportunities for enterprises that work in the Mekong Delta’s agricultural sector, which are led by or significantly benefit women and contribute to the sector’s resilience to climate adaptation.

The Partnerships are part of the Australian Government’s AU$94.5 million investments for climate change adaptation in the Mekong Delta.

I have been involved in many climate and sustainability projects, but The Bali Women Climate Entrepreneurs project (which has now evolved into The Matangi Bali Project) has been both humbling and exhilarating, unlike any other. Discussions on women, climate, and entrepreneurship has been a journey of discovery – gradually revealing new perspectives and cultivating an atmosphere where trust and empowerment flourish.

“Matangi” directly translates to “wake up” and embodies the essence of reviving Balinese communities and their symbiotic unity with nature. The Matangi Bali Project aims to develop an innovative and entrepreneurial approach to sustainable growth in Bali.

When thoughts turn to Bali, visions of its mesmerizing azure skies, enchanting oceans and stunning architecture immediately come to mind. Indeed, Balinese culture has embraced the ethos of harmonious coexistence with nature. Renowned for its deeply ingrained and rich cultural heritage, this ethos permeates every facet of its community.Despite being entrenched in patriarchal norms and cultural favoritism towards men, the lasting impact of Balinese culture and its identity, which has fuelled a tourism-driven economy to the island, owes much of its influence to the women. Balinese women, who play pivotal roles in various spheres of life – be it within the family, in economic pursuits, or in upholding traditions, are often overlooked. Their culture places the responsibility of shaping the nation’s next generation squarely on the shoulders of mothers to instill cultural values such as moral integrity, spirituality and environmental consciousness.

How will these women, deeply rooted in community values yet constrained by a strong patriarchal system navigate the path towards climate entrepreneurship? It’s a question that invites exploration.

Here are six valuable learnings that have shaped my perspective on this project.

1. Admitting and embracing the unknown

The first and most crucial lesson learned is admitting our own limitations. Rather than succumbing to preconceptions, we chose humility and opted to inquire. We met the women entrepreneurs where they are, seeing the world through their eyes. Understanding the context and cultural nuances has been essential in tailoring our program to the unique challenges women in Bali face.

2.  The art of community and collaboration

To overcome deeply ingrained cultural practices, collaboration with the community is key. The Matangi Bali Project actively contributes to the growth of the community while seeking input from its members. By acknowledging that societal change is a collective effort, we empower women to step into leadership roles and challenge the status quo.

3.  Setting realistic expectations

Navigating the intricacy of Bali’s patriarchal landscape comes with challenges. Setting realistic expectations has been crucial. Our goal was never about changing millenia-old cultural beliefs. Instead, it has always been about recognizing that men and women are capable of equality and that entrepreneurship is a pursuit open to both genders.

For generations, Balinese culture has embraced the ideals of a circular economy. Amid rapid urbanization and burgeoning tourism, these concepts seem to have been overlooked.

Our goal is to shed light on the untapped economic potential inherent in these principles, fostering a diverse range of economic activities across Bali. The profound impact of COVID-19 pandemic, particularly with the cessation of tourism, has understored the urgency of our mission.

We are steadfast in our commitment to position entrepreneurship as a key catalyst for economic resurgence in Bali. While the path might be bumpy, the commitment to progress remains unwavering.

4. Beyond ‘preaching to the choir’

It’s not enough to preach to the perfect-sounding choir. Instead, we orchestrate concerts, inviting others to listen and sing along.

Choosing to become an entrepreneur is a career path that is often frowned upon by many Balinese. Countless individuals have expressed that it can be a solitary journey, which frequently acts as a barrier to actively participate in climate efforts. This applies even more for mothers, who may only find time for such pursuits once everyone else is asleep.

This can compound issues such as diminished self-esteem, resulting in a lack of competitive drive, especially amidst existing biases against local products and services in a landscape heavily influenced by foreign perspectives on sustainability, often perceived as superior or even ideal.

Creating inclusive spaces where diverse voices are heard and valued is crucial for fostering a supportive environment for women entrepreneurs.

5. Respecting women’s agency

We strive to unlock a path where every woman can chart their own course. Empowering these entrepreneurial spirits goes beyond mere encouragement; it’s about honoring their autonomy and granting them the reins to shape their own stories.

Picture this: women juggling countless responsibilities, squeezed for time, and stretched thin by limited budgets. Yet, amid these challenges, they persist, prioritizing the needs of others while silently battling the stigma of environmental indifference. In the northern reaches of Bali, an economically disadvantaged region where meeting basic needs takes precedence, these women are unfairly scapegoated for their plastic usage, despite it being a convenient and affordable option for them.

And did you know? In the realm of waste management education, it’s the women who consistently bear the brunt of blame, their shoulders weighed down by the burden of societal expectations.

These stories form the basis of our understanding for running this critical project . Our role is simple yet important: to stand beside them, offering support as best as we can, to navigate their entrepreneurial journeys with confidence and resilience.

6. Meeting halfway

By continuously assessing the program’s needs, we ensure that we are making a tangible difference in the lives of women entrepreneurs. The impact goes beyond economic success; it extends to personal transformation, newfound confidence, and a deepened sense of belonging within their community.

At each twist and turn, we encounter multiple challenges. It’s a voyage that demands patience, empathy, and a whole lot of collaboration. Despite these challenges, we remain committed to being responsive and resilient. We’re ready to transform the insights gleaned from the grassroots levels to innovative solutions, ensuring we always meet those we support.

As we embark on the second phase of the program, these learnings will serve as our guiding light, propelling us towards innovative solutions despite gender barriers within the climate sector in Bali.

The Matangi Bali Project

The Matangi Bali Project aims to develop an innovative and entrepreneurial approach to sustainable growth  in Bali.

Our journey in Bali began in 2021, where we extended capacity building support to women climate entrepreneurs, fostering innovative solutions despite gender barriers within the climate sector. Recognizing the limitations of solely empowering one group, we have pivoted our approach to encompass broader participation, encouraging all stakeholders – including men, women, youth, government,  and communities – to embrace and cultivate leadership organically. This effort ensures that diverse voices contribute to sustainable solutions addressing climate change effectively. 

This project is initiated by New Energy Nexus Indonesia as part of the Bali Net Zero Emissions Coalition with CAST Foundation, IESR & WRI Indonesia. Matangi Bali  is supported by ClimateWorks Foundation and ViriyaENB.
