Cancellation of INNA Project Preserves Chile's Astronomical Heritage

The cancellation of the INNA project, a proposed $10 billion green hydrogen and ammonia production facility in Chile's Atacama Desert, has been celebrated by the scientific community for preserving the region's pristine astronomical conditions. The facility, which would have included a port, transport links, and three solar power plants, was under evaluation by Chile’s environmental regulator for nearly a year before its formal withdrawal.

Astronomers had expressed significant concerns regarding the INNA project's proximity to key observatories, including the Paranal Observatory, which houses the Very Large Telescope (VLT). The facility was located just 11.6 kilometers from the observatory, raising fears of increased light pollution, vibrations affecting sensitive instruments, and dust settling on telescope mirrors. Itziar de Gregorio, the European Southern Observatory’s representative in Chile, stated, “This cancellation means that the INNA project will no longer have a negative impact on the Paranal Observatory.” However, she emphasized the ongoing need for protective measures around sites critical to professional astronomy in Chile.

Chile’s environmental evaluation service confirmed the project's cancellation following discussions with AES Andes, the company behind the proposal. AES Andes, a subsidiary of the US-based AES Corporation, acknowledged the decision in a press release, stating that it had “decided to cease the execution of the INNA project” while asserting that the project was “absolutely compatible” with other activities in the area. The cancellation was also influenced by an open letter from prominent scientists, including 2020 Nobel Prize winner Reinhard Genzel, advocating against the project due to its potential adverse effects on astronomical research.

Despite the project's cancellation, concerns remain regarding the future of astronomical research in the Atacama Desert. Critics argue that the INNA project highlighted the urgent need for clear protective regulations to safeguard the region's unique observational conditions. The scientific community continues to call for measures that ensure the integrity of the skies above Chile, particularly as the Extremely Large Telescope (ELT) is under construction on nearby Cerro Armazones, which is expected to be the largest and most powerful telescope ever built.

The cancellation of the INNA project opens the door for further discussions on environmental protections surrounding astronomical sites in Chile. As the scientific community advocates for stronger regulations, the focus will likely shift towards ensuring that future developments do not compromise the integrity of the Atacama Desert's skies, which are crucial for groundbreaking astronomical discoveries.
