Carbon capture and storage (CCS) [credit: cnet.com]


Aren’t they in effect spelling out why the target is unachievable, not to say ridiculous? Whichever way you look at it – cost, feasibility, technology, benefits (lack of?) etc. – it has failure written all over it.

Britain’s goal of achieving net zero emissions by mid-century is achievable but immediate action is needed across a range of technologies including carbon capture and storage (CCS), electricity grid operator National Grid said.

Last year Britain became the first major economy to pass a law to bring all greenhouse gas emissions to net zero by 2050, compared with its previous target of at least an 80% reduction from 1990 levels, says yahoo!finance.

“Reaching net zero carbon emissions by 2050 is achievable. However, it requires immediate action across all key technologies and policy areas, and full engagement across society and end consumers,” National Grid said in its annual Future Energy Scenarios report.

Here comes more climate propaganda, but it gives some details of how the hydrogen might be produced if the proposals ever take off. The thorny subject of cost is not mentioned, which is usually a sign that it’s going to be way up high compared to today’s standard fuels. Using electricity to make electricity, with hydrogen in the middle, sounds clunky to say the least but climate obsessives wave away such niggles.

Eco-friendly hydrogen is regarded as a “silver bullet” [Talkshop comment: or maybe not] when it comes to fighting climate change, asserts Deutschland.de.

With its hydrogen strategy, Germany is now promoting its production.

Hydrogen is regarded as a kind of miracle substance. In an engine or fuel cell, it burns when oxygen is added and becomes pure water.

It can be transported in pipelines or in liquefied form on tankers. Easily storable, it can replace fossil fuels in virtually every situation: in lorries, cars and trains, and in the production of steel, cement and chemicals.

Hydrogen-powered London bus


More hopeless than hope. But for those who want to put a lot of time, effort and money into looking for ‘solutions’ to the non-problem of supposedly human-caused climate change, it’s a topic for discussion. It may have some specific uses, but cost and practicality seem to be strongly against it as a general replacement for traditional fuels.

Can hydrogen – a relatively clean source of fuel – help power the economy of the future? – asks the BBC.

In his speech on the planned economic recovery, the prime minister said hydrogen technology is an area where the UK leads the world. He hopes it’ll create clean jobs in the future.

But is the hydrogen revolution hope or hype?

From GreenTech media

The EU is currently working through the details of a €1.85 trillion ($2.08 trillion) recovery package. Before the stimulus was signed, a leaked document by the European Commission’s Directorate-General for Energy (DG Energy) ran through a serious of policy plans to marry the European Green Deal and the COVID-19 recovery effort.

Those plans included a possible 15-gigawatt EU-wide renewable tender designed to help make up for a shortfall in national tenders. Support for green hydrogen was also advanced as a potential item for inclusion.

But the plans have not survived a barrage of lobbying by vested interests and pushback from member states still married to a more traditional energy mix, according to multiple sources following the green recovery’s development.

A tank of hydrogen is obviously lighter than an equivalent fixed-weight battery pack, and filling up is much quicker than any recharge, but in many ways hydrogen cars struggle to compete, according to The Conversation. Very few manufacturers are interested in them any more, and list prices look higher even than EVs.

Hydrogen has long been touted as the future for passenger cars.

The hydrogen fuel cell electric vehicle (FCEV), which simply runs on pressurised hydrogen from a fuelling station, produces zero carbon emissions from its exhaust.

It can be filled as quickly as a fossil-fuel equivalent and offers a similar driving distance to petrol.

Browsing twitter recently I ran across this short video of a solar flare shot a few days ago.

After asking for some clarification on frame rate I was really intrigued.

Saturn’s hexagon


The ever-mysterious hexagon goes under the microscope, or telescope at least.

A rich variety of meteorological phenomena takes place in the extensive hydrogen atmosphere of Saturn, a world about 10 times the size of the Earth.

They help us to better understand similar features in the Earth’s atmosphere, says Phys.org.

Among Saturn’s atmospheric phenomena is the well-known “hexagon,” an amazing wave structure that surrounds the planet’s polar region.

Hydrogen-powered London bus


Fare-paying travellers can rejoice in subsidising the buses and the means of producing the fuel for them, i.e. the wind turbines, under this plan. Maybe do the same for trains too.

The owner of manufacturer Wrightbus has said he hopes to bring another 1,500 jobs to Ballymena as he pushes for a Government subsidy to fund the building of more than 3,000 buses in the town, reports the Belfast Telegraph.

Jo Bamford, executive chairman of the historic bus-builder, said the use of hydrogen could usher in a new era of environmentally-friendly transport.

It’s seeking subsidy funding of £500m from the UK Government, with the aim of building over 3,000 hydrogen-fuelled buses in Ballymena by 2024.
