The Norwegian Government’s Hydrogen Strategy - Towards a Low Emission Society
Jun 2020
Publication
On Wednesday 3rd of June 2020 Norwegian Minister for Petroleum and Energy Tina Bru and Minister for Climate and Environment Sveinung Rotevatn presented the Norwegian government's hydrogen strategy.<br/>The strategy sets the course for the government's efforts to stimulate development of hydrogen-related technologies. Hydrogen as an energy carrier can contribute to reduction of greenhouse gases and create value for the Norwegian business sector. The government wishes to prioritise efforts in areas where Norway Norwegian enterprises and technology clusters may influence the development of hydrogen related technologies and where there are opportunites for increased value creation and green growth. For hydrogen to be a low-carbon or emission-free energy carrier it must be produced with no or low emissions such as through water electrolysis with renewable electricity or from natural gas with carbon capture and storage.<br/>Today technology maturity and high costs represent barriers for increased use of hydrogen especially in the transport sector and as feedstock in parts of industry. If hydrogen and hydrogen-based solutions such as ammonia are to be used in new areas both the technology and the solutions must become more mature. In this respect further technology development will be vital.

Scaling up renewables to meet the 1.5ºC climate goal
As global economies aim to become carbon neutral competitive hydrogen produced with renewables has emerged as a key component of the energy mix. Falling renewable power costs and improving electrolyser technologies could make ""green"" hydrogen cost competitive by 2030 this report finds.
Green hydrogen can help to achieve net-zero carbon dioxide (CO2) emissions in energy-intensive hard-to-decarbonise sectors like steel chemicals long-haul transport shipping and aviation. But production costs must be cut to make it economical for countries worldwide. Green hydrogen currently costs between two and three times more than ""blue"" hydrogen which is produced using fossil fuels in combination with carbon capture and storage (CCS).
This report from the International Renewable Energy Agency (IRENA) outlines strategies to reduce electrolyser costs through continuous innovation performance improvements and upscaling from megawatt (MW) to multi-gigawatt (GW) levels.

This report from the International Renewable Energy Agency (IRENA) outlines strategies to reduce electrolyser costs through continuous innovation performance improvements and upscaling from megawatt (MW) to multi-gigawatt (GW) levels.
Among the findings:
- Electrolyser design and construction: Increased module size and innovation with increased stack manufacturing have significant impacts on cost. Increasing plant size from 1 MW (typical in 2020) to 20 MW could reduce costs by over a third. Optimal system designs maximise efficiency and flexibility.
- Economies of scale: Increasing stack production with automated processes in gigawatt-scale manufacturing facilities can achieve a step-change cost reduction. Procurement of materials: Scarcity of materials can impede electrolyser cost reduction and scale-up.
- Efficiency and flexibility in operations: Power supply incurs large efficiency losses at low load limiting system flexibility from an economic perspective.
- Industrial applications: Design and operation of electrolysis systems can be optimised for specific applications in different industries. Learning rates: Based on historic cost declines for solar photovoltaics (PV) the learning rates for fuel cells and electrolysers – whereby costs fall as capacity expands – could reach values between 16% and 21%.
- Ambitious climate mitigation: An ambitious energy transition aligned with key international climate goals would drive rapid cost reduction for green hydrogen. The trajectory needed to limit global warming at 1.5oC could make electrolysers an estimated 40% cheaper by 2030.
Thermodynamic, Economic and Environmental Assessment of Renewable Natural Gas Production Systems
May 2020
Publication
One of the options to reduce the dependence on fossil fuels is to produce gas with the quality of natural gas but based on renewable energy sources. It can encompass among other biogas generation from various types of biomass and its subsequent upgrading. The main aim of this study is to analyze under a combined technical economic and environmental perspective three of the most representative technologies for the production of biomethane (bio-based natural gas): (i) manure fermentation and its subsequent upgrading by CO2 removal (ii) manure fermentation and biogas methanation using renewable hydrogen from electrolysis and (iii) biomass gasification in the atmosphere of oxygen and methanation of the resulted gas. Thermodynamic economic and environmental analyses are conducted to thoroughly compare the three cases. For these purposes detailed models in Aspen Plus software were built while environmental analysis was performed using the Life Cycle Assessment methodology. The results show that the highest efficiency (66.80%) and the lowest break-even price of biomethane (19.2 €/GJ) are reached for the technology involving fermentation and CO2 capture. Concerning environmental assessment the system with the best environmental performance varies depending on the impact category analyzed being the system with biomass gasification and methanation a suitable trade-off solution for biomethane production.
Hydrogen Valleys. Insights Into the Emerging Hydrogen Economies Around the World
Jun 2021
Publication
Clean hydrogen is universally considered an important energy vector in the global efforts to limit greenhouse gas emissions to the "well below 2 °C scenario" as agreed by more than 190 states in the 2015 Paris Agreement. Hydrogen Valleys – regional ecosystems that link hydrogen production transportation and various end uses such as mobility or industrial feedstock – are important steps towards enabling the development of a new hydrogen economy.<br/><br/>This report has been issued during the setup of the "Mission Innovation Hydrogen Valley Platform" which was commissioned by the European Union and developed by the Fuel Cells and Hydrogen Joint Undertaking. The global information sharing platform to date already features 30+ global Hydrogen Valleys with a cumulative investment volume of more than EUR 30 billion. The projects provide a first-of-its kind look into the global Hydrogen Valley project landscape its success factors and remaining barriers. This report summarizes the findings and presents identified best practices for successful project development as well as recommendations for policymakers on how to provide a favourable policy environment that paves the way to reach the Hydrogen Valleys' full potential as enablers of the global hydrogen economy.
Hydrogen from Renewable Power
Sep 2018
Publication
As the world strives to cut carbon emissions electric power from renewables has emerged as a vital energy source. Yet transport and industry will still require combustible fuels for many purposes. Such needs could be met with hydrogen which itself can be produced using renewable power.
Hydrogen provides high-grade heat helping to meet a range of energy needs that would be difficult to address through direct electrification. This could make hydrogen the missing link in the transformation of the global energy system.
Key sectors for renewable-based hydrogen uptake include:
Electrolysers – which split hydrogen and oxygen – can make power systems more flexible helping to integrate high shares of variable renewables. Power consumption for electrolysis can be adjusted to follow actual solar and wind output while producing the hydrogen needed for transport industry or injection into the gas grid.
In the long run hydrogen could become a key element in 100% renewable energy systems. With technologies maturing actual scale-up should yield major cost reductions. The right policy and regulatory framework however remains crucial to stimulate private investment in in hydrogen production in the first place.

Rising To the Challenge of a Hydrogen Economy: The Outlook for Emerging Hydrogen Value Chains, From Production to Consumption
Jul 2021
Publication
For many a large-scale hydrogen economy is essential to a a clean energy future with three quarters of the more than 1100 senior energy professionals we surveyed saying Paris Agreement targets will not be possible without it.
DNV’s research Rising to the challenge of a hydrogen economy explores the outlook for emerging hydrogen value chains from production to consumption. It combines the wider view from the energy industry with commentary from business leaders and experts. Our research finds that the challenge is not in the ambition but in changing the timeline: from hydrogen on the horizon to hydrogen in our homes businesses and transport systems.
We see that the energy industry is rising to this challenge. By 2025 almost half (44%) of energy companies globally involved in hydrogen expect it to account for more than a tenth of their revenue rising to 73% of companies by 2030 – up significantly from just 8% of companies today. The research identifies infrastructure and cost as two of the biggest hurdles while the right regulations are deemed the most powerful enabler followed by carbon pricing. Proving the safety case will also be key to scaling the hydrogen economy.

Shipping the Sunshine: An Open-source Model for Costing Renewable Hydrogen Transport from Australia
Apr 2022
Publication
Green hydrogen (H2) is emerging as a future clean energy carrier. While there exists significant analysis on global renewable (and non-renewable) hydrogen generation costs analysis of its transportation costs irrespective of production method is still limited. Complexities include the different forms in which hydrogen can be transported the limited experience to date in shipping some of these carrier forms the trade routes potentially involved and the possible use of different shipping fuels. Herein we present an open-source model developed to assist stakeholders in assessing the costs of shipping various forms of hydrogen over different routes. It includes hydrogen transport in the forms of liquid hydrogen (LH2) ammonia liquified natural gas (LNG) methanol and liquid organic hydrogen carriers (LOHCs). It considers both fixed and variable costs including port fees possible canal usage charges fuel costs ship capital and operating costs boil-off losses and possible environmental taxes among many others. The model is applied to the Rotterdam-Australia route as a case study revealing ammonia ($0.56/kgH2) and methanol ($0.68/kgH2) as the least expensive hydrogen derivatives to transport followed by liquified natural gas ($1.07/kgH2) liquid organic hydrogen carriers ($1.37/kgH2) and liquid hydrogen ($2.09/kgH2). While reducing the transportation distance led to lower shipping costs we note that the merit order of assumed underlying shipping costs remain unchanged. We also explore the impact of using hydrogen (or the hydrogen carrier) as a low/zero carbon emission fuel for the ships which led to lowering of costs for liquified natural gas ($0.88/kgH2) a similar cost for liquid hydrogen ($2.19/kgH2) and significant increases for the remainder. Given our model is open-sourced it can be adapted globally and updated to match the changing cost dynamics of the emerging green hydrogen market.
Closing the Low-carbon Material Loop Using a Dynamic Whole System Approach
Feb 2017
Publication
The transition to low carbon energy and transport systems requires an unprecedented roll-out of new infrastructure technologies containing significant quantities of critical raw materials. Many of these technologies are based on general purpose technologies such as permanent magnets and electric motors that are common across different infrastructure systems. Circular economy initiatives that aim to institute better resource management practices could exploit these technological commonalities through the reuse and remanufacturing of technology components across infrastructure systems. In this paper we analyze the implementation of such processes in the transition to low carbon electricity generation and transport on the Isle of Wight UK. We model two scenarios relying on different renewable energy technologies with the reuse of Lithium-ion batteries from electric vehicles for grid-attached storage. A whole-system analysis that considers both electricity and transport infrastructure demonstrates that the optimal choice of renewable technology can be dependent on opportunities for component reuse and material recycling between the different infrastructure systems. Hydrogen fuel cell based transport makes use of platinum from obsolete catalytic converters whereas lithium-ion batteries can be reused for grid-attached storage when they are no longer useful in vehicles. Trade-offs exist between the efficiency of technology reuse which eliminates the need for new technologies for grid attached storage completely by 2033 and the higher flexibility afforded by recycling at the material level; reducing primary material demand for Lithium by 51% in 2033 compared to 30% achieved by battery reuse. This analysis demonstrates the value of a methodology that combines detailed representations of technologies and components with a systemic approach that includes multiple interconnected infrastructure systems.

Study of the Microstructural and First Hydrogenation Properties of TiFe Alloy with Zr, Mn and V as Additives
Jul 2021
Publication
In this paper we report the effect of adding Zr + V or Zr + V + Mn to TiFe alloy on microstructure and hydrogen storage properties. The addition of only V was not enough to produce a minimum amount of secondary phase and therefore the first hydrogenation at room temperature under a hydrogen pressure of 20 bars was impossible. When 2 wt.% Zr + 2 wt.% V or 2 wt.% Zr + 2 wt.% V + 2 wt.% Mn is added to TiFe the alloy shows a finely distributed Ti2Fe-like secondary phase. These alloys presented a fast first hydrogenation and a high capacity. The rate-limiting step was found to be 3D growth diffusion controlled with decreasing interface velocity. This is consistent with the hypothesis that the fast reaction is likely to be the presence of Ti2Fe-like secondary phases that act as a gateway for hydrogen.
Mathematical Description of Energy Transition Scenarios Based on the Latest Technologies and Trends
Dec 2021
Publication
This work dedicated to a mathematical description of energy transition scenarios consists of three main parts. The first part describes modern trends and problems of the energy sector. A large number of charts reflecting the latest updates in energy are provided. The COVID-2019 pandemic’s impacts on the energy sector are also included. The second part of the paper is dedicated to the analysis of energy consumption and the structure of the world fuel and energy balance. Furthermore a detailed description of energy-efficient technologies is given. Being important and low-carbon hydrogen is discussed including its advantages and disadvantages. The last part of the work describes the mathematical tool developed by the authors. The high availability of statistical data made it possible to identify parameters used in the algorithm with the least squares method and verify the tool. Performing several not complicated steps of the algorithm the tool allows calculating the deviation of the average global temperature of the surface atmosphere from preindustrial levels in the 21st century under different scenarios. Using the suggested mathematical description the optimal scenario that makes it possible to keep global warming at a level below 1.7 ◦C was found.
Committee for Climate Change Fifth Carbon Budget: Central Scenario Data
Jul 2016
Publication
This spreadsheet contains data for two future UK scenarios: a "baseline" (i.e. no climate action after 2008 the start of the carbon budget system) and the "central" scenario underpinning the CCC's advice on the fifth carbon budget (the limit to domestic emissions during the period 2028-32).<br/>The central scenario is an assessment of the technologies and behaviours that would prepare for the 2050 target cost-effectively while meeting the other criteria in the Climate Change Act (2008) based on central views of technology costs fuel prices carbon prices and feasibility. It is not prescriptive nor is it the only scenario considered for meeting the carbon budgets. For further details on our scenarios and how they were generated see the CCC report Sectoral scenarios for the Fifth Carbon Budget. The scenario was constructed for the CCC's November 2015 report and has not been further updated for example to reflect outturn data for 2015 or changes to Government policy.

Publication
This is our sixth statutory report to Parliament on progress towards meeting carbon budgets. In it we consider the latest data on emissions and their drivers. This year the report also includes a full assessment of how the first carbon budget (2008-2012) was met drawing out policy lessons and setting out what is required for the future to stay on track for the legislated carbon budgets and the 2050 target. The report includes assessment at the level of the economy the non-traded and traded sectors the key emitting sectors and the devolved administrations. Whilst the first carbon budget has been met and progress made on development and implementation of some policies the main conclusion is that strengthening of policies will be needed to meet future budgets.
Public Acceptability of the Use of Hydrogen for Heating and Cooking in the Home: Results from Qualitative and Quantitative Research in UK<br/>Executive Summary
Nov 2018
Publication
This report for the CCC by Madano and Element Energy assesses the public acceptability of two alternative low-carbon technologies for heating the home: hydrogen heating and heat pumps.
These technologies could potentially replace natural gas in many UK households as part of the government’s efforts to decrease carbon emissions in the UK.
The report’s key findings are:
These technologies could potentially replace natural gas in many UK households as part of the government’s efforts to decrease carbon emissions in the UK.
The report’s key findings are:
- carbon emissions reduction is viewed as an important issue but there is limited awareness of the need to decarbonise household heating or the implications of switching over to low-carbon heating technologies
- acceptability of both heating technologies is limited by a lack of perceived tangible consumer benefit which has the potential to drive scepticism towards the switch over more generally
- heating technology preferences are not fixed at this stage although heat pumps appear to be the favoured option in this research studythree overarching factors were identified as influencing preferences for heating technologies.
- perceptions of the negative installation burden
- familiarity with the lived experience of using the technologies for heating
- perceptions of how well the technologies would meet modern heating needs both hydrogen heating and heat pumps face significant challenges to secure public acceptability

The first part of the review is available here: The Fourth Carbon Budget Review – part 1: assessment of climate risk and the international response (November 2013).<br/>According to the Climate Change Act 2008 carbon budgets can only be altered if there is a significant change in circumstances upon which the budget was set. Any such change in circumstances must be demonstrated through evidence and analysis.<br/>The Fourth Carbon Budget Review – part 2 considers the impacts of meeting the 2023-2027 budget. The review concludes that the impacts are small and manageable and identifies broader benefits associated with meeting the fourth carbon budget including: improved energy security improved air quality and reduced noise pollution.
Quantifying Greenhouse Gas Emissions
Apr 2017
Publication
In this report Quantifying Greenhouse Gas Emissions the Committee on Climate Change assesses how the UK’s greenhouse gas emissions are quantified where uncertainties lie and the implications for setting carbon budgets and measuring progress against climate change targets. The report finds that:
- The methodology for constructing the UK’s greenhouse gas inventory is rigorous but the process for identifying improvements could be strengthened.
- There is high confidence over large parts of the inventory. A small number of sectors contribute most to uncertainty and research efforts should be directed at improving these estimates.
- UK greenhouse gas emissions for 2014 were within ±3% of the estimated level with 95% confidence which is a low level of uncertainty by international standards.
- Methodology revisions in recent years have tended to increase estimated emissions but these changes have been within uncertainty margins.
- Statistical uncertainty in the current greenhouse gas inventory is low but could rise in future.
- Uncertainty also arises from sources of emissions not currently included in the inventory and from potential changes to IPCC guidelines.
- Independent external validation of greenhouse gas emissions is important and new monitoring techniques should be encouraged.
- Government should continue to monitor consumption-based greenhouse gas estimates and support continued research to improve methodology and reduce uncertainty in these estimates.
The Sixth Carbon Budget & Welsh Emissions Targets Summary of Responses to Call for Evidence Summary
