What Alternō does
Alternō is a Singapore-domiciled climate-tech company founded in 2023 in Saigon, Vietnam by Hai Ho, Kent Nguyen, and Nam Nguyen. The company develops and commercializes sand battery thermal energy storage systems that store renewable electricity as high-temperature heat (up to 600°C) using sand as the storage medium. Its product portfolio includes Alternō Hybrid, a thermal battery system designed for rural agro-processing applications, and Alternō Mini, a compact unit for small-scale facilities planned for public debut at Tokyo ENEX 2026. Alternō has filed a patent on its core sand battery technology. The company serves three target verticals — agriculture, industrial, and residential heating — with named enterprise customers including PepsiCo Foods, DoTea, and Ecovi Farm & Village, and a stated long-term goal of reducing 100 million tons of CO2 emissions annually by 2030.
The company operates a sales-led, enterprise-focused go-to-market combining bespoke engineered solutions for large-scale projects with plug-and-play systems for rapid deployment. Revenue is generated through three pricing models: upfront hardware sales, Heat-as-a-Service (pay-per-use thermal energy with no upfront payment), and a deferred payment Buy Now Pay Later program, all quote-based and not publicly disclosed. Distribution relies on direct enterprise field sales supported by regional partnerships, with a regional headquarters in Singapore and a wholly-owned Japanese subsidiary, Alternō Japan GK, in Tsukuba City. Manufacturing partnerships with Kikuchi Seiki Co., Ltd. and Yamazaki Industry Co., Ltd. support pilot-scale production and product localization for the Japanese market. Initial deployment markets span Vietnam, Mongolia, and Japan across Southeast, East, and Central Asia.
Alternō has raised over US$1.5 million in seed funding co-led by The Radical Fund and Touchstone Partners (April 2024), a VND 15 billion (~US$630,000) grant from the Net Zero Challenge 2023, an Antler pre-seed (February 2023), and closed an undisclosed Series A in May 2025 led by UntroD Capital Asia with ADB Ventures participation. The company was named a top-three finalist in the Clean Energy & Storage category at the 2026 Start Up Energy Transition Awards in Berlin. Headcount remains small at 1-10 employees.
