Scaling Bioenergy with Carbon Capture
Announced today, May 20, 2026, the deal officially commits the bioenergy company to supplying Microsoft (MSFT) with 650,000 Carbon Removal Units (CRUs) over the duration of the contract [1][4]. Each CRU corresponds to one metric ton of carbon dioxide that has been extracted from the atmosphere and securely sequestered [1]. While the contract averages 92857.143 CRUs annually, deliveries are slated to begin with a partial batch in the second half of 2026 [alert! ‘The exact month of the initial delivery remains unspecified in the provided statements’], eventually targeting a run rate of 100,000 CRUs per year through 2032 [1][5]. This volume represents the largest offtake agreement in BioCirc’s history [5].
