It was very interesting developing these short @apolitical.bsky.social courses for civil servants on electricity grids, featuring a range of Imperial experts, including @iain-staffell.bsky.social. Any non-experts in government looking to learn about future electricity networks, check these out! 👇

Built for public servants at any level working across the energy ecosystem, we've partnered with @apolitical.bsky.social to create two practical self-paced courses that teach: ⚡How electricity systems work ow.ly/3r8s50YcbSp 🔌How to future-proof electricity grids ow.ly/1ciR50YcbSL Sign-up today ✍️

We are all used to stories of the UK in decline… Electricity is no exception: demand has fallen for 20 years as we outsource industry. But Britain has turned a corner: demand up two years in a row. AI data centres now consume more power than Birmingham and could 4x by 2030.

previous decade across several countries.

MISLEADING: A new academic paper by @qmul.bsky.social has attracted significant media attention by claiming that EVs & heat pumps deliver no proven carbon savings in UK ahead of 2030 clean power target - and should therefore be postponed. Here is why this paper should never have been published.🧵

UK-based high density pumped hydro firm RheEnergise has successfully generated electricity for the first time - they tell me they hit their full output capacity of 500 kilowatts. Here's my piece from late last year which discusses their tech: share.google/gomKZ5pZ4aEG...

Pumped Hydro Energy Storage Is Having a Renaissance

As the world looks to incorporate more renewables into energy grids, centuries-old systems that can balance supply and demand are being reappraised and innovated upon.

We interviewed UK climate activists and oil & gas employees on what the energy transition should look like. I expected polarisation. Instead: surprising shared ground on urgency, cutting demand, and how government must set the pace. Can we achieve more together? www.cell.com/iscience/ful...

Britain's electricity demand has turned a corner. After twenty years of de-industrialisation... electric cars, heat pumps and data centres meant demand grew by 3% this year. And that growth was more than met by renewables, so emissions keep falling. www.thetimes.com/business/ene...

Demand for electricity in UK surges after two decades of decline

Electric vehicles, heat pumps and AI data centres are driving a new era of electrification, with renewables helping to meet the extra demand

Batteries are now Britain’s biggest form of energy storage. More than 6 GW installed and ~45 GW already consented or being built! But, batteries aren't going to solve the problems of wind curtailment... Long-duration storage is the next big challenge.

There will be no transition without transmission! Power grids are the hidden star of the net-zero story. Our new study maps how Europe's Transmission System Operators are using innovation to keep ahead. From NWAs to AI, see what they are doing here: www.sciencedirect.com/science/arti...

For decades, forecasts of a clean hydrogen economy have relied on rapid scale-up driving down costs. However, production costs are dominated by engineering and energy, and supplemented by transport, storage & usage costs which seem unlikely to exhibit rapid reductions. www.nature.com/articles/s44...

Realistic roles for hydrogen in the future energy transition - Nature Reviews Clean Technology

Hydrogen has been proposed as a fuel for widespread use since the 1970s, but uptake has repeatedly fallen below projections, primarily due to high costs. This Perspective considers hydrogen’s potentia...
