Climate-tech startup Alternō raised Series A funding from UntroD Capital Asia, ADB Ventures

Alternō, a climate-tech startup based in Singapore, has closed its Series A funding round to support its goal of eliminating 100 million tons of carbon dioxide (CO₂) emissions annually by 2030 and to expedite the deployment of its sustainable heat technology.

By constructing the next generation of clean energy infrastructure, which will supply heat, electricity, and energy management driven by artificial intelligence (AI), the company said in a statement on Tuesday that it hopes to revolutionize how the world powers its farms, factories, and communities.

The fact that UntroD Capital Asia led the round and that ADB Ventures, the Asian Development Bank’s venture arm, participated shows how investors are becoming more confident in scalable climate solutions for challenging industries.

Antler’s early institutional support, which was crucial to Alternō’s early development, has sustained the company’s growth to date.

“This funding marks a pivotal milestone for Alternō. With the support of ADB and UntroD, we’re accelerating our efforts to bring large-scale, cost-effective decarbonization to industrial sectors，

“This isn’t just another battery—it’s a revolution in how we generate and use industrial heat, starting from something as simple as sand，” said Hai Ho, Co-Founder and Chief Executive Officer of Alternō.

Alternō is a Singapore-based climate-tech startup that was founded in 2023 and has manufacturing and research and development (R&D) facilities in Vietnam.

The business creates thermal battery systems based on sand that provide high-temperature, emission-free heat for use in agriculture and industry.

Alternō is growing its portfolio to meet energy needs at the factory and community levels with the help of its most recent funding.

Among these is Alternō One, a small thermal battery that provides clean heat to isolated communities and off-grid residences.

The system, which was successfully piloted in Lâm Đồng, Vietnam, is currently getting ready for its first deployment in Mongolia, where it will enhance energy access and help fight severe winter air pollution.

This also includes Alternō Hybrid, the first modular thermal battery that combines biomass and electric heating in the world.

Designed to provide a constant supply of heat for rural agro-processing, it allows farmers to turn organic waste into energy. This solution has the potential to completely transform Vietnam’s agricultural drying methods.
