Offshore will be vital after 2050 — but for getting to Net Zero proven land-based renewables remain key. 3/3

The role of offshore wind and solar PV resources in global low-carbon transition Offshore wind and solar PV could meet nearly 30% of 2050 electricity demand using only 1% of suitable ocean areas.

A study in @ScienceMagazine shows wind & solar in just 1% of coastal waters could generate 22 PWh/yr — nearly all global electricity. However

Just 1% of coastal waters could power a third of the world’s electricity – but can we do it in time? Offshore wind and solar have tremendous potential but still face many challenges – new study.

Building #renewables on land is getting harder as good sites run out

🌊 What if we build wind and solar at sea?

I, @jdjewell.bsky.social & Tim Kazlou argue in @uk.theconversation.com that only a small share of the vast offshore potential can be used by 2050 theconversation.com/just-1-of-co... 1/3

Sure. But as soon as a solution is "on the list" we should be able to do a feasibility assessment similar to that we did for CCS here.

That's true, but neither of those can support negative emissions or contribute in other niche CCS applications. So we need CCS even if all renewables and related tech develop astronomically fast.

Our recent @natureportfolio.bsky.social paper with TKazlou & @acherp.bsky.social argues there is little hope #CCS can grow fast enough for 1.5°C target. The 2°C target is realistic if CCS failure drops fast and CCS expands as fast as mainstream energy technologies. www.nature.com/articles/s41...
