Altern\u014d, a rising climate-tech venture with roots in Singapore and Vietnam, has closed its Series A round to scale its patented sand-based thermal energy storage systems.<\/p>\n
The funding, led by UntroD Capital Asia with participation from ADB Ventures, will fuel the deployment of its clean heat solutions aimed at reducing 100 million tons of CO\u2082 annually by 2030.<\/p>\n

Its proprietary sand battery stores heat at up to 600\u00b0C using affordable, abundant materials, offering a sustainable, low-emission alternative for industrial operations.<\/p>\n Decarbonising industrial heat remains one of the toughest challenges in climate tech. In Asia, where fossil fuels still dominate manufacturing and agricultural processes, affordable, high-temperature clean heat solutions are urgently needed. Altern\u014d’s thermal storage technology arrives at a critical juncture, offering an economically viable route to decarbonise processes such as drying, heating, and pasteurisation.<\/p>\n Sand’s thermal stability and cost-effectiveness make it a surprisingly potent material for heat storage, particularly for emerging markets where cost barriers hinder adoption of more expensive alternatives like metals or phase-change materials.<\/p>\n Altern\u014d’s technology has already been deployed in agro-processing and industrial drying use cases across Vietnam, working with clients like PepsiCo and Mondelez. The systems have demonstrated tangible impacts: reducing reliance on fossil fuels, lowering energy costs, and improving product quality and consistency.<\/p>\n “This funding marks a pivotal milestone for Altern\u014d,” said Hai Ho, Co-Founder and CEO. “With the support of ADB and UntroD, we’re accelerating our efforts to bring large-scale, cost-effective decarbonisation to industrial sectors. This isn’t just another battery\u2014it’s a revolution in how we generate and use industrial heat, starting from something as simple as sand.”<\/p>\n The Series A raise will also support the rollout of two new products:<\/p>\n Altern\u014d One<\/strong>: A compact battery designed for off-grid homes and remote communities. After a successful pilot in L\u00e2m \u0110\u1ed3ng, Vietnam, it is being prepared for deployment in Mongolia, where it could help mitigate extreme winter air pollution.<\/p>\n Altern\u014d Hybrid<\/strong>: A modular solution combining electric and biomass heating, enabling 24\/7 heat in rural agro-processing. Farmers can repurpose organic waste into energy, a move that could transform agricultural drying across Vietnam.<\/p>\n Both systems are connected through IoT and optimised using AI, allowing for remote monitoring and continuous performance enhancement. To scale faster, Altern\u014d offers heat-as-a-service (HaaS), allowing clients to access decarbonised heat without upfront capital expenditure. It is also engaged in co-development talks with multinationals like Honda and Marubeni, signalling growing global interest in its technology.<\/p>\n Altern\u014d’s innovation has been recognised globally. It won the 2024 PepsiCo Greenhouse Accelerator for Asia-Pacific and placed second in the global Startup World Cup.<\/p>\n Altern\u014d’s rise underscores the growing viability of hardware-heavy climate innovations in Asia, especially those tailored to local conditions. For startups and investors, it highlights the opportunities in overlooked segments like industrial heat and agro-processing\u2014areas ripe for disruption but often sidelined in mainstream cleantech discourse.<\/p>\n Also Read: Vietnam\u2019s sand-based thermal energy storage startup Altern\u014d secures US$1.5M<\/a><\/strong><\/p>\n By marrying frugal engineering with advanced energy analytics, Altern\u014d provides a blueprint for building scalable climate solutions in the Global South, starting with Southeast Asia.<\/p>\n With Series A funding secured, Altern\u014d is gearing up for international deployments and deeper industrial integration. Its focus on flexible financing, localised production, and strategic partnerships suggests a strong roadmap for regional expansion\u2014and a meaningful step toward climate impact at scale.<\/p>\n —<\/p>\n Enjoyed this read?
