Heliosync

Heliosync OÜ develops an alignment system for heliostat mirrors used in solar thermal applications. The system samples the radiant footprint on the receiver at multiple points and returns these samples to each mirror as retro-reflected light, so each heliostat can optimise its alignment. It also supports dynamic heat load adjustment and lighter heliostat construction.

The target customers are operators of solar thermal facilities. The website names concentrated solar power electricity production, cement and hydrogen as relevant industries. The company claims its alignment improves mirror accuracy by about 30%, adds up to €30,000 per MW per year in thermal energy output, and reduces downtime and mirror calibration labour by up to 99%.

Heliosync OÜ was founded in April 2023 and is registered in Estonia, with its headquarters in Papsaare. The team listed on the website includes a CEO, a CTO, a technical director and a marketing and sales strategy advisor. The company was a 1st round winner of the American-Made Heliostat Prize and is part of the Beamline Accelerator Deeptech Batch.

Product: Closed-loop heliostat alignment system that uses retro-reflected light samples from the receiver to correct mirror pointing.
