The North Sea Investment Pact: When mechanism matters more than volume

The North Sea Summit on 26 January was about far more than offshore wind targets. It was a deliberate political signal from the North Sea countries that clean energy is now inseparable from security, resilience and industrial policy.

From the peloton to the pavement: why truck charging is a different race entirely

I really love cycling, but I’ll be the first to admit it’s a bit of a crazy sport. I probably drove my ex-girlfriend crazy with rigid training schedules, and the fixed spot for my indoor trainer was always a “hard-fought” negotiation. To the partners of cyclists who have yielded to these demands: I thank you. To those who haven’t: I understand.

Running on empty – is Europe running out of gas? (Spoiler alert: not yet, but maybe soon)

After 20 years of marriage, I am thinking of divorcing my wife because she won’t buy petrol. I still love her madly, but she has this incredibly annoying habit of taking the car out with the petrol light on, driving on a jaunty 20-mile round trip, then bringing it back with the seat too far forward, the radio on too loud, and that little pump light now angrily flashing. This sounds trivial, but after 20 years and eight different cars, it has become unbearable.  I won’t divorce her, of course. Instead, I’ll just write irritable introductions to blogs about energy storage and the importance of refilling the tanks.

Biomethane and beyond: is the UK missing out on a big opportunity? (spoiler alert, yes)

When I left university, I took a job in the Civil Service and almost immediately regretted it. It wasn’t even a bad job, which was part of the problem. The office was clean. The coffee machine mostly worked. There was a lunchtime Subbuteo league that some people took far too seriously. The work had a vague sense of purpose. I met my first wife there.  On paper, it ticked a lot of boxes: progression, stability, a respectable CV. All that stuff. In reality, it felt terminal. A career and a wife in my early 20s, before anything had really started. I remember thinking I’d probably stopped the search at least one decision too early. Forty years later, I think we’re doing something similar with UK biomethane. Not the wrong thing, just stopping asking questions too early.
