Update on the SPICE project

Stratospheric Particle Injection for Climate Engineering (SPICE) is an EPSRC, NERC and STFC-funded project that includes a work package on assessing the feasibility of injecting particles into the stratosphere from a tethered balloon for the purposes of solar radiation management.

EPSRC has taken the decision to delay the experiment planned in October, to allow time for more engagement with stakeholders. We have adopted a responsible innovation approach with this project – as part of our commitment to responsible development - and our decision to pause the test bed experiment reflects the advice that we have received from our advisory panel following a stage gate.

The technology test would have involved pumping water to a height of 1km through a suspended hose, held aloft by a helium-filled balloon. This would allow the engineers to study how the hose and balloon behave over time in a variety of weather conditions
