A successful 2% green hydrogen gas mixing trial has been successfully completed at the Briggs power station in North Lincolnshire. This is said to be the first occasion in which a green hydrogen and natural gas blend have been transported through infrastructure to power electrical generation in the UK. The trial was carried out by Centrica and British Gas to demonstrate the feasibility of hydrogen gas blends into existing UK infrastructure.

Across Europe several other separate hydrogen trials involving gas blending are on-going. Countries such as The Netherlands, Germany and Portugal are all in the process of using hydrogen in household appliances, experimenting with hydrogen gas blending in existing infrastructure or adapting existing infrastructure to transport 100% hydrogen in the near future.

Further details on of each trial has been released in a report by the European Clean Hydrogen Alliance in April 2025 titled: “Hydrogen-readiness of gaseous fuels distribution infrastructure and heating technologies in Europe.”

The European Clean Hydrogen Alliance was started in 2020 by the European Commission and is a collective organisation of over 1,700 members – all of whom are involved in the hydrogen market value chain including governments, private and public investors, research institutions and commercial enterprises.

The European Clean Hydrogen Alliance states its aims as to promote financial investment into hydrogen as well as stimulate hydrogen production and use within the scope of climate friendly boundaries. To achieve these goals the organisation has divided itself into three separate groups of focus:

 

  • hydrogen production

  • hydrogen transmission, distribution, and storage

  • hydrogen end-use

 

The first trial refers to “Hydrogen City,” a project that is located in Stad aan ‘t Haringvliet, situated on the island of Goeree-Overflakkee in The Netherlands. The local community has voted to stop using natural gas as a primary fuel and will instead use locally sourced green hydrogen.

In between 2025 and by the latest 2030 all existing gas infrastructure will be repurposed to transport hydrogen into every domestic and commercial property within the municipality.

Portugal’s leading gas operator Floene has begun a 12% green hydrogen natural gas blend project in Seixal, a city near Lisbon. Newly constructed infrastructure will carry green hydrogen to the local transmission network where a blended mix of green hydrogen and natural gas will be fed to 80 residential, commercial and industrial end users.

By 2030 the Portuguese government is aiming to provide a 15% green hydrogen natural gas mix in all domestic supplies.

A German project – H2Direkt is led by energy providers Energie Sudbayern, Energienetze Bayern and utility consultants Thuga. 10 private households and 1 commercial customer have been receiving 100% hydrogen since 2023 in the Bavaria region.

The original test schedule finish date has been recently extended and will go beyond the current year. Initial results of the test indicate that even when exposed to temperatures of -15°C the entire hydrogen infrastructure and the hydrogen heating systems were reliable.

Hydrogen has been identified as a potential gaseous component of the global energy transition. As demonstrated by the four UK and European examples of hydrogen blending and 100% hydrogen usage in this article, progress is being made in highlighting the potential operational value of hydrogen introduction.

WHAT MIGHT THE GENERAL ELECTION MEAN TO THE INDUSTRY?

WILL IT BE A BRAVE NEW WORLD OR JUST MORE OF THE SAME?

 

 

Chris Goggin reviews the NetZero policy statements espoused by both of the main political parties this side of the General Election and considers the viability of these plans and  gives a summary of the key issues regarding investment, infrastructure and cost evaluated against the trajectory of the international energy market and realistic domestic requirements.

 

 

A potential change of government is thought to be likely after the forthcoming General Election. If a change of direction in UK governance is introduced a redrafting of every major UK policy will take place. One area of legislation that remains an important pillar of political discussion is the question of energy – its supply, its price, its security and its impact on NetZero.

To provide a brief overview: the current opposition believes that renewable generation should be expanded far beyond the present government’s ambitions. Nuclear expansion will also be pursued whilst all North Sea drilling contracts will be honored. However, the opposition’s long-term plan is to shelve oil and gas usage in favour of carbon reducing alternative energies.

A more detailed look reveals discrepancies between the opposition and the current government’s approach to all critical areas of UK energy. However, additional renewable energy integration into the UK grid is reliant upon electrical grid upgrades that assist in renewable grid connections. Both political parties have separate plans for UK electric grid upgrading, later visited in this article.

Solar power will be tripled from 15.6 GW to 50 GW of installed capacity, whilst onshore wind will be more than doubled from 15 GW to 35 GW. Green hydrogen targets will also be doubled from 5 GW to 10 GW. Existing nuclear projects will also be completed alongside the completion of smaller nuclear projects such as the construction of small modular reactors.  Clean offshore wind production will be quadrupled to 55GW by 2030.

Although the opposition has pledged to increase investment into hydrogen and CCUS (Carbon Capture & Storage) it has not been highlighted how this strategy would best result in a mutually beneficial outcome. For instance, the opposition has not stated whether they will purchase or invest in privately owned hydrogen projects or construct their own hydrogen projects.

A cornerstone of the opposition’s energy policy will be the creation of GB Energy which has been recently described in The Guardian as:

“a state-owned investment vehicle and company working alongside and often in partnership with the existing private sector suppliers. The plan is for it to be largely invisible to households, not offering electricity directly to consumers but financing and helping to build low-carbon infrastructure, from windfarms to – potentially – nuclear reactors.”

GB Energy will have access to £8.3 billion of capital to assist in the completion of strategic objectives. £3.3 billion will be directed towards the construction of localized smaller power projects whilst £5 billion will be invested into larger projects and supply chains. This money will be raised through the taxing of North Sea fossil fuel companies.

Both UK political parties believe that decarbonising the national electricity grid remains a priority that will enable cheaper customer costs and increase clean energy usage across the entire UK. However, they are yet to agree on an appropriate pathway that secures beneficial economic and societal benefits.

The opposition believe decarbonising the UK energy grid by 2030 can be achieved through capacitating £116 billion of investment, whilst the current government’s plan is to extend the 2030 timeline to 2035 and absorb £104 billion of additional subsidy. Time and finance are central issues to both strategies. Both approaches have been labelled as viable and non-realistic, according to which political party an individual subscribes to.

A financial breakdown report was commissioned by Policy Exchange, a research institute that aims to influence domestic and international policy. The report was completed by an independent energy market analytics company – Aurora Energy Research

The current opposition will require huge amounts of capital investment to achieve their aim of decarbonising. Aurora has calculated that £15.6 billion a year until 2030 is required (total £93.5 billion) and a further £4.4 billion a year from 2031 – 2035 (£22.5 billion) equating to a total of £116 billion over the next 11 years.

In contrast current government plans to decarbonise the UK’s power grid by 2035 will require £8.2 billion a year of additional investment until 2030 – a total of £49.3 billon. A further £11.1 billion a year of additional investment from 2031 – 2035 a total of £55.3 billion. The total accumulative investment over 11 years will amount to £104.6 billion over the next 11 years.

The approach undertaken by the current opposition when compared to the present Govt party focuses on the expanding of renewables, hydrogen and nuclear in a shorter span of time at increased financial expense.

We need to keep in mind also that future energy policy by both UK political parties is dependent on wider international energy market conditions and geopolitical influences. There is no doubt that there are no easy or quick answers to the question of providing energy to both commercial and domestic markets.
