Hydrogen for homes is a terrible idea. We should fight it

October 30, 2020

A plan to pipe hydrogen, instead of natural gas, to millions of UK households is being pushed hard by the fossil fuel industry. It sounds “green” – but could wreck efforts to make homes truly zero carbon, using insulation and electric heat pumps.

Oil and gas companies support switching the gas grid to hydrogen, as a survival option in case of decarbonisation, as hydrogen is usually fabricated from gas.

But the hydrogen strategy cuts across the approach recommended for years by housing

policy wonks and architects: to use insulation to slash the amount of heat needed, and install electric pumps (which work like fridges in reverse).

Leeds Trades Union Council (TUC) last month launched a campaign in favour of retrofitting homes with high-quality insulation and heat pumps.

It’s an issue many people can unite around – those fighting for better housing and tenants’ rights, campaigners against fuel poverty, trades unionists fighting building industry cuts, and all of us who want to tackle climate change.

And there’s a choice to be made we cannot avoid.

If the gas grid is switched to hydrogen, that will block for good the electrification-and insulation approach, that heats homes better, more cheaply, with technology that we know works, and is truly zero-carbon. We cannot have it both ways.

We will be locked into extra dependency on fossil fuels, instead of speeding the shift away from them.

That gas-to-hydrogen switch is being planned in north-east England by Northern Gas Networks (NGN): its H21 project would convert 3.7 million homes and businesses by Read the rest of this entry »

India climate crisis: this is about capitalism and inequality

October 6, 2020

Global warming is upsetting the monsoon, making droughts more likely, and changing the lives of hundreds of millions of Indians, writes NAGRAJ ADVE, in a guest post based on his pamphlet, Global Warming in the Indian Context.  

The average sea level rise worldwide over 2016-2020 was nearly half a centimetre per year, says the United in Science 2020 report, published last month by the World Meteorological

Organisation (WMO), Intergovernmental Panel on Climate Change (IPCC) and other scientific institutions.

The rate of sea level rise is now significantly higher than the 20th century average, largely due to the loss of ice from the great ice sheets on Antarctica and Greenland, besides warmer ocean waters expanding.

Reading the United in Science 2020 report made me think about sea level rise in terms of centimetres rather than millimetres – for the first time in the 15 years that I have been engaging with the climate crisis.

The impact of rising waters in the Indian sub-continent is one of the many issues covered in a new edition of my pamphlet, Global Warming in the Indian Context, published today by People & Nature.  I have updated the pamphlet – which was first published on People & Nature in June 2016 – to highlight many things about the climate crisis that have changed since then.

But the first thing to emphasise is that the social context in which climate change hits people in India is very different from that in the UK or mainland Europe.

■ In India, 650 million people rely on agriculture or related occupations; the average landholding per household is merely 2.5 acres, and half the area is under key crops such as rice and wheat;

■ Millions of small and marginal farmers have no access to irrigation, are entirely dependent on the rain, and hence more vulnerable to climatic changes; and

■ In the world’s most disastrous Covid-induced lockdown, 120 million people have lost their jobs or livelihoods – and there is no sign of economic recovery in sight.

Extreme climatic events have been getting more intense and frequent in India (and worldwide) in recent years – particularly extreme rainfall events. These result in floods, loss Read the rest of this entry »
