The forthcoming 2020 United Nations Climate Change Conference, otherwise known as COP26, to be hosted by the UK in November 2020 will hopefully be a tipping point where sustainability rhetoric is converted into action.
Although, not receiving much media attention, the UK has already made considerable progress in building the foundations of a Net Zero carbon emissions target by 2050 and is well positioned to be a world leader, not only in championing this target, but in delivering it.
A conference on Carbon Capture and Storage (CCS) and Hydrogen Decarbonisation was held in Birmingham at the start of February and was attended by over 200 government officials, energy experts, utility service providers, researchers and consultants.
While the UK currently produces and imports 284.1 Mtoe (2018 data) (1 Mtoe = 11.63 TWh) with only 9% produced by renewables (see UK Energy Flow Chart below), this can be changed through a combination of measures that are on the point of being developed. These include the use of more sustainable lower carbon transition fuels before 100% sustainable energy is achieved by around 2100.
This will be achieved by moving the UK economy off fossil fuels to renewable electricity and hydrogen, with hydrogen potentially being the big game changer. Currently hydrogen is mostly produced from fossil fuels without CCS (Grey H2) through steam methane reforming. However, there are plans to ramp up production with CCS (Blue H2) in the next decade at a number of industrial hubs around the country including Merseyside, Teesside, Humberside and the Thames Gateway. Again, this will need a natural gas feedstock.
Blue H2 represents a transition fuel that will still see the UK using 80% of today’s natural gas consumption by 2050. However, with CCS and offsetting through tree planting, this would deliver the Net Zero Carbon Emissions target. The CCS will be achieved through flue gas capture, transportation through existing pipelines to depleted gas reservoirs in the North and Irish seas. This would deliver by 2050.
The ambition is to utilise the UK’s continental shelf wind to generate large scale ‘Green H2’. Government funded research is being carried out in the Dolphyn project to combine floating wind turbines and electrolysis plants to produce offshore hydrogen. This would then be piped to shore through existing redundant oil and gas pipelines in the North Sea. The first 2MW trial is scheduled to be constructed off the coast of Scotland in 2023.
The planning for initially introducing a 20% hydrogen mix into the natural gas network is underway with the final objective of converting it to 100% hydrogen between 2070 and 2100. This would allow the existing stock of gas central heated residential homes to be converted to zero emission ‘Green H2’ at relatively low cost.

The following infographic is an example of the inter-relationships in the proposed North West HyNet Project – one of the five main industrial hydrogen hubs.
On 18th February the UK Government department, BEIS, announced the results of the Phase 2 Hydrogen Supply Competition. Five winning projects have been awarded a total of £28 million.
