Climate Group Warns World Must Not Fall for Hydrogen ‘Hype’

“Rather than betting on unproven and inefficient hydrogen technologies, we need rich countries to put their money towards a just energy transition,” said a Friends of the Earth campaigner.

Amid preparations for COP28, the United Nations climate summit kicking off next week, a leading green group warned Tuesday that “hydrogen is big polluters’ latest trick, and we can’t afford to fall for it.”

“Hydrogen is being promoted as a ‘clean’ alternative to the fossil fuels used for domestic heating, transport, and heavy industry,” explains the new Friend of the Earth International (FOEI) paper, Don’t Fall for the Hydrogen Hype, put out ahead of the global clilmate talks. “But it’s expensive to produce, inefficient, and far from a low-carbon solution. In fact, the majority of the global hydrogen supply is made from fossil fuels.”

After COP27, all signs point to world blowing past the 1.5 degrees global warming limit – here’s what we can still do about it

The world could still, theoretically, meet its goal of keeping global warming under 1.5 degrees Celsius, a level many scientists consider a dangerous threshold. Realistically, that’s unlikely to happen.

Part of the problem was evident at COP27, the United Nations climate conference in Egypt.

While nations’ climate negotiators were successfully fighting to “keep 1.5 alive” as the global goal in the official agreement, reached Nov. 20, 2022, some of their countries were negotiating new fossil fuel deals, driven in part by the global energy crisis. Any expansion of fossil fuels – the primary driver of climate change – makes keeping warming under 1.5 C (2.7 Fahrenheit) compared to pre-industrial times much harder. Continue reading

How not to solve the climate change problem

When politicians talk about reaching “net zero” emissions, they’re often counting on trees or technology that can pull carbon dioxide out of the air. What they don’t mention is just how much these proposals or geoengineering would cost to allow the world to continue burning fossil fuels.

There are many proposals for removing carbon dioxide, but most make differences only at the edges, and carbon dioxide concentrations in the atmosphere have continued to increase relentlessly, even through the pandemic.

‘Monstrous’ Methane Plume Seen From Space Highlights Invisible Fracking Dangers

“While this event is particularly severe, Louisiana is already forced to live through an exorbitant amount of pollution daily from fossil fuel and petrochemical plants.”

Environmental justice advocates on Wednesday pointed to a methane plume so large it was seen last month from space via satellite as the latest evidence that emissions of the potent fossil fuel must be reined in.

As Bloomberg reported Monday, the geoanalytics firm Kayrros SAS detected the plume of the invisible greenhouse gas, which spanned 56 miles and covered several parishes across Louisiana, on January 21. Continue reading
