There are no natural hydrogen deposits on earth, it has to be extracted from other compounds by a chemical process. These vary on whether green hydrogen must be produced from renewable energy, on the boundaries of the carbon accounting system, the emission thresholds at which hydrogen is considered green, and on which feedstocks and production technologies are included in the scheme. 0 In gaseous form, hydrogen at 350 bar pressure would need storage of about 250 m3, compared to only 85 m3 in liquid form. Liquid hydrogen has been chosen for the first ferry project in Norway, with the hope of creating a bridge to more vessels. Hydrogen can be distributed compressed, liquefied or through a pipeline. Lately, major gas producers have made public plans to increase the global production capacity of liquid hydrogen from 300 to 400 tonnes per day.

The production price is significantly reduced by setting up large scale production facilities, but to keep the transportation costs down you need large consumers nearby. 3944 0 obj <>/Filter/FlateDecode/ID[<5AF6CB54DAB08F42AE8BF7FB8135ED9C><6B5F9D6925524B4992866635F2B6F34D>]/Index[3926 43]/Info 3925 0 R/Length 100/Prev 1517897/Root 3927 0 R/Size 3969/Type/XRef/W[1 3 1]>>stream The resulting hydrogen can be used later to return electricity to the grid via a fuel cell. There is not a universally accepted definition for green hydrogen. However, a key question remains, the use of emission-free hydrogen. Policies must be aligned with those of other energy carriers to avoid discrimination. Guarantees of origin demonstrate to consumers that they are using green hydrogen. Hydrogen can also be produced by the electrolysis of water (using an electric current to break water, H2O, into its component elements of hydr… ����~~��1n ���T�s�M�����b�Ÿce��E[�������q�t��22���h��-$���2���1U�������QŪ>�&A�@��yK���j�.

Around 97% of Norwegian electricity production comes from hydropower and with 15 TWh of excess capacity currently available, new ways of utilising this green power are needed. © 2020 Elsevier Ltd. All rights reserved. Most existing green hydrogen initiatives are in Europe. On the flip side, fuel cells have a higher efficiency than combustion engines, reducing the amount of energy needed. Hydrogen has some fantastic characteristics as a zero-emission energy carrier. Producing hydrogen in this way is sometimes referred to as brown or grey or even blue hydrogen!

However, hydrogen from natural gas with CCS is only economically viable in large scale, several hundred tonnes per day and close to existing CCS infrastructure, leaving room for green hydrogen to cover most of the domestic market in Norway where smaller projects in the range of a few hundred kilos per day to some tonnes per day will be the typical project size.

As long as we release this CO2 into the air, we call this product “grey hydrogen”. Around 97% of Norwegian electricity production comes from hydropower and with 15 TWh of excess capacity currently available, new ways of utilising this green power are needed. In anticipation of a future market for green hydrogen, international standards are starting to be discussed by national and international standardisation organisations and policy makers. Supply vessels, cruise ships and for that matter large bulk ships, travel far greater distances than an express boat or car ferry and will need much more fuel. In the form of hydrogen, surplus and trapped renewable energy can be stored, distributed and made accessible to growing zero emission markets, both in Norway and abroad, placing our country in a unique position when it comes to green hydrogen production. The climate puzzle is far from done, but with hydrogen, we are holding a key piece that can Make Green Happen! As the sale price of hydrogen will be a result of the production and the transportation costs this will vary depending on the location of the consumer and of the power source. However, hydrogen must not be seen as the only solution. The barrier has always been the cost of delivering hydrogen “green.” These vary on whether green hydrogen must be produced from renewable energy, on the boundaries of the carbon accounting system, the emission thresholds at which hydrogen is considered green, and on which feedstocks and production technologies are included in the scheme.

The vast majority of industrial hydrogen is currently produced from natural gas through a process known as steam methane reforming or SMR. However, in the Netherlands and the rest of the world, most hydrogen is currently being produced via steam-methane (from natural gas) reforming, which produces hydrogen and CO2.

Therefore, there are use cases for both compressed and liquefied hydrogen depending on energy demands and space availability. Norway has a large production of natural gas with a yearly export of nearly 1000 TWh. It can be produced anywhere from renewable energy and works very well as a range extender in existing electrical drive lines. https://doi.org/10.1016/j.enpol.2020.111300. There are two solutions to this problem; compression and liquefaction, the second of which offers the best density at the expense of costs and complexity.

If hydrogen is to be a zero emission solution, then hydrogen production from renewable electricity must increase and facilities producing it via natural gas reforming must implement carbon capture and storage.

Please note: This is a commercial profile. A range of approaches have been taken to defining green hydrogen and guarantees of origin. Harmonisation of guarantees of origin would facilitate international trade. The challenge ahead is, therefore, to increase the tempo even faster, encourage the production of truly zero emission hydrogen and take advantage of economies of scale.

By fueling the distribution trucks and ships with hydrogen, the value chain is green all the way from production to consumer. %PDF-1.5 %���� For example, a supply vessel to the oil and gas industry would need about six tonnes of hydrogen for a standard three-day operation.

Hydrogen will, in combination with batteries and a share of sustainable biofuel, play a key role in the transition to a 100% zero emission transport. The first mention of green hydrogen in EU policy documents is the declaration for establishing a green hydrogen economy in Europe (European Parliament, 2007). Infinitely available and potentially green, hydrogen comprises an ever-growing share of the world’s energy mix.

Both on land and by sea, hydrogen could be distributed in compressed or in liquefied form. For hydrogen to have a role in future low-carbon energy systems, it is necessary to demonstrate that it has sufficiently low carbon emissions. Still, an important area of development is larger storage tanks, suited for long distances. CertifHy will boost demand and supply of green hydrogen throughout Europe: by the . There is not a universally accepted definition for green hydrogen. Several green characterisation initiatives are under development.

This paper explores how green hydrogen has been defined, reviews nascent green hydrogen characterisation initiatives, and highlights the main challenges that standards and guarantee of origin schemes must overcome to develop a market for green hydrogen.

When setting up a hydrogen production plant, the question of whether to place the facility close to the consumer or close to the power production is raised.

Decisions on these factors are often influenced by other national and international standards, and the legal framework in which the green hydrogen supply chain operates.

In short, it takes up less weight but more space than the current solutions. 3968 0 obj <>stream Definition of Green Hydrogen • Introduction • Definition of green hydrogen – Criteria for a green H2 produced by GHG “virtuous” plants – Renewable share: definition and illustrations – Application of the two GHG thresholds – Examples • Q&A Agenda . Definition of Green Hydrogen, outcome & scope LCA analysis. Hydrogen can be produced from many different renewable and non-renewable feedstocks and technological pathways, with widely varying greenhouse gas emissions.

Green Hydrogen is hydrogen that not only meets the low-carbon threshold but is generated using renewable energy sources such as solar or wind. But there is a solution: CCS. Green hydrogen is produced when renewable power is used in the electrolysis process.

For the Norwegian gas industry, hydrogen could provide a new market and even if green energy from renewable energy is the favourable solution in a climate perspective, hydrogen with CCS (carbon capture storage) could boost the transition by securing stable large-scale production from existing facilities.
