The Hackney Campaign To Bring The North London Line Back From The Brink In The 80s

The title of this post is the same as that of this article on the Hackney Gazette.

It is an interesting insight into life before the London Overground and how the section between Highbury & Islington and Stratford stations was created from a freight line, that hadn’t had passenger services for several decades.

It also talks about Broad Street station.

I used to use this station to travel from Ipswich to Metier’s offices at Stonebridge Park.

It was just a short walk from Liverpool Street station next door and then a train to Willesden along a very much forgotten North London Line, before taking the Bakerloo Line. It avoided the very crowded route via Baker Street station.

How Much Energy Can Extracted From a Kilogram Of Hydrogen?

This article on EnergyH, is entitled About Hydrogen Energy.

This is said.

Hydrogen has an energy density of 39 kWh/kg, which means that 1 kg of hydrogen contains 130 times more energy than 1kg of batteries. So lots of energy can be stored with hydrogen in only a small volume.

But as in most things in life, you can’t have it all as fuel cells are not 100 %  efficient.

Wikipedia has a sub-section which gives the in-practice efficiency of a fuel cell, where this is said.

In a fuel-cell vehicle the tank-to-wheel efficiency is greater than 45% at low loads and shows average values of about 36% when a driving cycle like the NEDC (New European Driving Cycle) is used as test procedure. The comparable NEDC value for a Diesel vehicle is 22%. In 2008 Honda released a demonstration fuel cell electric vehicle (the Honda FCX Clarity) with fuel stack claiming a 60% tank-to-wheel efficiency.

For the purpose of this exercise, I’ll assume a conservative forty percent.

This means that a kilogram of hydrogen would generate 16 kWh

Raise that efficiency to fifty percent and 19 kWh would be generated.

Conclusion

Fuel cell efficiency will be key.

Energy Efficient Bricks Made From Human Waste To Help Build London Homes

The title of this post is the same as that of this article in The Standard.

This is the first two paragraphs.

New homes and factories will be built from bricks made out of the human waste of four million Londoners.

Dried sewage from millions of homes will be transformed into two million heavy-duty breeze blocks a year.

It’s all happening at Beckton.
