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?

A cruise ship uses about 250 ton's of fuel a day.

thats 227 tonne's
Which is 2.7 GWh

Good luck with your batteries and charging structure.

Hydrogen isn't ideal. You would need tanks at least 5 times bigger than oil and they would have to be cooled and under high pressure. It is however at least possible.

Seriously I was a member of the Battery Vehicle Society and am a fan of BEV's. However not all vehicles are cars and batteries don't suit all applications.

EU Hydrogen Strategy
https://www.oxfordenergy.org/wpcms/wp-c ... rategy.pdf

"Introduction
In the context of decarbonisation of the energy system, there has been a very rapid increase in interest
among industry, government, and other stakeholders over the past 12 months regarding the potential
for hydrogen. This has been covered in detail in two recent OIES papers.
1 The main focus on
decarbonisation in general and hydrogen in particular remains in Europe, but other countries are also
increasingly considering the potential of renewable hydrogen.
There has been a proliferation of published national hydrogen strategies, starting with Japan in 2017,
and subsequently followed by South Korea (2019), New Zealand (2019), Australia (2019), Netherlands
(2020), Norway (2020), Portugal (2020), Germany (2020) and, most recently on 8th July 2020, from the
European Union. The latter will be an important document for driving the hydrogen agenda in Europe,
so this short comment [by Oxford Energy] provides a brief review of the EU Hydrogen Strategy and consideration of the
way forward."

"Conclusion
The publication of the EU Hydrogen Strategy is a significant milestone on the journey to decarbonisation
of the energy system. It will provide a valuable framework for future, more detailed work on
implementation plans. It does provide a clear indication of the enormous size of the challenge, and, if
the ambition is to be achieved, the urgency of government action to support specific projects to
manufacture renewable hydrogen at scale. It is noteworthy that, in contrast to some earlier publications,
it does acknowledge the potential role of low-carbon hydrogen from fossil fuels, at least for a transition
period on the journey to the ultimate target of renewable hydrogen.
It does leave a number of questions unanswered, particularly in the area of regulation, where major
changes will be required to achieve the ambition outlined in the strategy. While it envisages an open,
competitive and liquid market for hydrogen with unhindered cross border trade in the long term, it is
less clear how this will be reached following a period of subsidies and incentives required to justify the
very significant investments to establish the required infrastructure.
OIES will continue to monitor and assess future developments based on the strategy in our future
publications"

The actual EU Hydrogen Strategy itself can be found here https://ec.europa.eu/energy/sites/ener/ ... rategy.pdf

Personally I think it will be niched into the heavy industrial petrochem areas. Still significant but not dominant.

Hydrogen-powered train makes UK maiden journey

A hydrogen-powered train has travelled on Britain’s rail network for the first time.

The prototype, called the Hydroflex, made a 25-mile round trip through Warwickshire and Worcestershire, reaching speeds of up to 50 mph.

Its next phase is to move the hydrogen tanks, fuel cell and battery out of a carriage and stash them underneath the train.

The aim is for the train to start carrying paying passengers by the end of 2021.

Neever mind moving the tanks and fuel cell to under the train, I want to know where all this hydrogen to run a regular passenger service is coming from, and who is paying for it.
