The good old days
This post is the second in the series ‘The Shape of Net Zero’. The series is based on an understanding that we cannot simply switch out one source of energy (fossil fuels) with another (wind, solar, nuclear and others) and carry on with Business as Usual. We need to consider the following parameters to do with a switch in the basics of our energy supply.
Renewable Energy. M.C. Escher's Waterfall (1961)
Renewables are growing faster than other sources of energy.
The fraction of energy provided by renewals is declining.

Most of the people reading posts such as this are aware that earlier this month the IPCC issued an alarming report on climate change that should make society change its ways. Failure to do so could lead to catastrophe and a possible breakdown of civilization within just 20 years. Yet nothing happened; the report changed almost nothing. It was just a blip in the torrent of news that we face every day.

One of the founders of the process safety discipline was Trevor Kletz (1922-2013). Probably his best eulogy is also the simplest, "He saved lives."
As we reflect on Trevor's contributions it is clear that one of his greatest gifts was that of telling stories. He wrote extensively on technical topics such as hazards analysis and inherent safety, but he is probably best remembered for his story-telling books such as Learning from Accidents and What Went Wrong? Human beings learn best from stories and Trevor knew it.
The purpose of a Prestartup / Operational Readiness Review (PSR) is to ensure that initial start-ups, or start-ups following major project work, proceed safely and smoothly. In particular, the PSR will check to make sure that all project activities are complete and that the system is ready for safe operation. It is a tool that the operations and maintenance departments use to make ensure that they have received what they expected to receive from the project team, and that no corners were cut, particularly with regard to safety.
