Hydrogen boom!

Hydrogen is extremely buoyant so it disperses upwards quickly. Pass by a vehicle fire quickly in case there is a fuel leak on the ground.

Increased NOx emissions can be tackled as TM pointed out.

If you remember pre- north sea gas then 50% hydrogen in town gas was quite normal for stoves and ovens, and if you are reading this .. you are still alive!

On the same site https://www.globalrailwayreview.com/news/137304/db-cargo-plans-transport-hydrogen-rail-germany/ states German ambition for H2 is roughly 11.4GW by 2030. In contrast UK only 10GW, yet UK has much greater wind & tidal energy potential. Just think where we could have been if... or worse, how far we will lag behind if decisions are to be deferred until 2026!?

Previously with Williams, acquired by Fortescue. Interesting...

I agree with you 100% Toneman.

The article notes that no start date has been given and that the study wont compare the life-cycle issues.

..and the UK gov is to sponsor a trial: £240M. Maybe this will get a basic H2 refueling grid built. Are ITM motive bidding??

I agree with others, we will follow Europe. If Germany is any indication
https://h2-map.eu/
then we ought to get going with hydrogen refuelling infrastructure.

It's coming here soon according to this: https://energynews.biz/800-hydrogen-refueling-stations-in-uk-network-by-2027/

Greed or green?

I was looking forward to H2 - Green Shield Stamps.. to encourage drivers not to hang about waiting for a battery charger. Top-up your H2 range extender instead and put a 'tiger in your tank'!

Nobody thought getting oil and gas out of the ground would be easy or economic
yet the demand for it drove a revolution in science, computing and engineering.
Arguably demand for portable energy in transportation was key.

Do not diminish the DEMAND for H2 at this critical stage for the climate and environment.

Negative views about use of H2 for vehicles coupled with too few H2 fuel stations is the problem here. How many who can afford a Tesla would actually prefer to pay a premium for HFCV instead for its similar ICE fuelling model? Prof Paul Dodds (UCL) identified that 60 strategically placed H2 forecourts would provide local enough access for 80% UK population. According to Shell that would only cost 60 x £2M. Come on someone, kick start the market! It will have to be done eventually when long distance freight switches to HFCV and starts arriving at Dover etc.

H2sciencecoalition's message was topical before COP26 during the last H2 investment peak. Has it muddied the waters for politicians and major investors, just when H2 and energy storage needed to be increased globally? If more had been done sooner, we would have been better prepared for this post covid/Russian energy crisis.

The podcast focuses on battery vs HFCV, despite HFCV being huge improvement on ICE vehicle efficiency, and is less demanding on the known limits to lithium battery growth. Why not mention the 'new Pi' = 3.3 efficiency factor, lots and lots of times, a sound-bite to satisfy your research sponsors..

As for catenary road charging, when H2 is being promoted for rail instead of high maintenance overhead electrification. Smaller (lighter) batteries are suggested, with more frequent recharging from catenaries above short sections of road. 10km of catenary accessed at 80km/h say: What charge rate is required to deliver a useful quantity in 7.5 minutes? There could be 50 such vehicles on the road, 200m apart. How many GWs to sustain that usefully?

To be fair the podcast ends, unsure how it will all pan out. As said, they are anti Blue H2 (CCUS) too.
By the way, another cool example of CCUS this week: Wintershall-DEA cleared to inject
5Mt CO2/year at Luna Norway. Global CO2 emissions now stand at 34Gt/year. A drop in the proverbial ocean.

Looking forward to this:

explains it much better, but I am biased my raft is wind powered:)

Paddington station: Major disruption continues due to power line damage

Replace with hydrogen powered trains: reduce infrastructure costs and maintenance burdens.

Reducing SHELL's OWN emissions is one target, but reducing customers' emissions is quite another thing. On one hand the risks of CCUS (& blue hydrogen) versus the currently low cost path to green hydrogen. SHELL's new CEO is currently Director Integrated Gas, Renewables and Energy Solutions, and was previously director of Upstream. A hint in the career progression perhaps..

Positive news.

Oversupply of energy, is certainly possible from offshore wind within a decade. Energy islands are planned. Floating wind farms are planned. This is commerce at work, provided the energy prices still justify the investment! As Bilbo says, any nuclear development large or small takes much time and money. Maintenance problems and lack of cooling water plague France's nuclear industry and all this is before you factor in the decommissioning costs. Ramping up power generation is one thing, storage is the other key factor. Power2gas H2 fits nicely as we need that anyway to decarbonize transport and other industries. So yes the opportunities are huge and happening, but our government is not signalling this properly, they are playing to a public opinion which they believe is a vote winner. There is nothing wrong with hedging bets though, but that needs to be more clearly stated. Running down nuclear and gas storage was short sighted but even Germany was guilty of this. I would like to see more tidal power projects for baseload generation, but their energy potential is lower and costs high, and they tend to impede my raft...;)

Should do if this is to be believed:

Caption competition suggestions:

=switch on our electrolysers and make hydrogen with excess electricity

https://www.bbc.co.uk/news/science-environment-62731923

points out that renewable electricity is currently about x9 cheaper than that produced from gas. So making H2 from the excess wind-power is a "no brainer".

ITM are involved:

I am sure a lot has already been said about the win-win of waste to energy tech-projects like EQTECs, positively tackling the causes & effects of global warming. The heatwave across UK and Europe and consequential wild fires shows there is huge potential for such projects. Likely offsetting the costs of forest management while lowering fire risks.

There cannot be very much blue hydrogen produced yet as it has to be reliant on carbon capture. Of that there are only about 30 CCS projects globally. These only aim to capture about 0.1% of current global emissions, at best. CCS needs to work without leaks for about 10000 years to be effective. Don't hold your breath. My money is on a massive increase in renewable energy, e.g. floating offshore windfarms and green hydrogen. Much lower risk and higher likelihood of success. I sense the oilers know that too...
