We are reporting closely on the development of hydrogen, as a renewable energy source, and as a “green” gas. Hy4Heat have been making developments recently with the use of hydrogen gas. Here are links to a recent few articles:
The EUA (Energy & Utility Alliance) believes that “Green Gas” including hydrogen, has the potential to reduce emissions significantly, which is an area of utmost priority to educate the Government, and business and consumers alike.
A Focus on Hydrogen Purity:
As part of the on-going development of hydrogen as an energy source, Hy4Heat is looking at and reviewing the range of hydrogen production sources and purity levels in the UK. They also need to look at the cost effectiveness of introducing hydrogen at specific quality (purity) levels, especially so with regards to if/when the wider distribution network of hydrogen comes about.
The also need to look at and review the range of hydrogen production sources and purity levels available in the UK, and the possible impacts and cost effectiveness of introducing hydrogen at these quality levels, into the wider distribution network. Furthermore they need to recommend a purity level for use by the Hy4Heat programme, as part of an unoccupied trial. This relates to Hy4Heat Work Package 8 – more info can be found here.
Getting a Better Understanding of Hydrogen Purity Levels:
Below are some of the points and actions, which need to be considered to get a better understanding of hydrogen purity levels.
a. Report on the different hydrogen purity levels made in the UK, which will also include available production methods and the type and the amount of impurities found.
b. Get data from gas distribution networks on hydrogen impurities, which have been picked up by methane and likely to impact hydrogen.
c. Review the expected impurity level at the point of use from potential contributors, and an assessment of the potential economic impacts that might result.
d. Consider outputs and findings from other relevant work to ensure findings are aligned for the purity level recommended.
e. Recommend the best purity level of hydrogen to be delivered by a GB gas network to private and business users.
Determining The Best Purity Levels:
There are two key elements to take into account when determining the ideal purity levels for hydrogen in the grid:
1 – The first is to understand the level of purity considered acceptable and safe for hydrogen in the network, relating mostly to the level of carbon monoxide. This choice is made by the analysis of the extra costs of production linked with lowering levels of carbon monoxide.
2 – The second is to understand the impact of the different purity levels on the cost to different hydrogen users, to then know whether an increased level of purity could result in a reduction in the total system cost for a mix of all end-users of hydrogen.
Making sure the right purity levels are met will be crucial in the long term success of hydrogen as a fuel source on a mass scale.
