A recent two-day workshop in New Delhi brought together the Bureau of Indian Standards (BIS) and the British Standards Institution (BSI) to concentrate on the standardisation of green hydrogen production and related regulations. Supported by the UK's Foreign, Commonwealth and Development Office (FCDO), the event highlighted the collaboration's significance in aligning international standards within the emerging hydrogen economy in India and the UK. Abbey Dorian, Energy Sector Lead at BSI, emphasized the shared ambition of both countries to lead in the green hydrogen sector for a net zero future. The workshop focused on creating safe, scalable Regulations, Codes, and Standards (RCS), with discussions on public specification standards and global hydrogen certification. This initiative resonates with India's National Green Hydrogen Mission, aiming to bridge standardisation gaps and build expert networks crucial for the development of a competitive green hydrogen market.
