The Energy Innovation Needs Assessment (EINA) aims to identify the key innovation needs across the UK’s energy system to inform the prioritisation of public sector investment in low-carbon innovation. Using an analytical methodology developed by the Department for Business Energy & Industrial Strategy (BEIS) the EINA takes a systemlevel approach and values innovations in a technology in terms of the system-level benefits a technology innovation provides.1. This whole system modelling in line with BEIS’s EINA methodology was delivered by the Energy Systems Catapult (ESC) using the Energy System Modelling Environment (ESMETM) as the primary modelling tool.



To support the overall prioritisation of innovation activity the EINA process analyses key technologies in more detail. These technologies are grouped together into sub-themes according to the primary role they fulfil in the energy system. For key technologies within a sub-theme innovations and business opportunities are identified. The main findings at the technology level are summarised in sub-theme reports. An overview report will combine the findings from each sub-theme to provide a broad system-level perspective and prioritisation.



This EINA analysis is based on a combination of desk research by a consortium of economic and engineering consultants and stakeholder engagement. The prioritisation of innovation and business opportunities presented is informed by a workshop organised for each sub-theme assembling key stakeholders from the academic community industry and government.



This report was commissioned prior to advice being received from the CCC on meeting a net zero target and reflects priorities to meet the previous 80% target in 2050. The newly legislated net zero target is not expected to change the set of innovation priorities rather it will make them all more valuable overall. Further work is required to assess detailed implications.

The Fuel Cell Industry Review 2020 offers data analysis and commentary on key events in the industry in 2020. Now in its seventh year the Review has been compiled by a team led by E4tech - a specialist energy strategy consultancy with deep expertise in the hydrogen and fuel cell sector (see www.e4tech.com).



Despite the title of this publication we’ve said before that the fuel cell ‘industry’ is not a single industry at all. As those inside it know it is divided by different materials stages of maturity applications and regions – all contributors to the fact it has taken time to get going. But it does seem to be getting traction. Part of that is down to decades of hard work and investment in R&D technology improvement and demonstrations. Thankfully part of it is also down to changes in external conditions. Improving air quality is increasingly non-negotiable. Reducing greenhouse gas emissions likewise. And all while maintaining economic development and opportunity.



The growth spurt of the battery industry allied with some of the drivers above has catalysed thinking in where and how fuel cells can fit. Countries and regions which did not support batteries early on are scrambling to catch up and wish not to risk a repeat of their errors with fuel cells. So support is being targeted at industrial development and competitiveness as well as solving societal problems. Which in turn is helping industry to decide on and take investment steps: Weichai’s 20000 unit per annum PEM factory in China; Daimler and Volvo setting up their fuel cell truck JV; CHEM Energy building a factory for remote systems in S Africa."

On 26 June the World Energy Council held a webinar presenting the results of its latest Innovation Insights Brief on hydrogen engaging three key experts on the topic:



Nigel Brandon Dean of the Faculty of Engineering Imperial College London



Craig Knight Director of Industrial Solutions Horizon Fuel Cell Technology



Dan Sadler H21 Project Manager for Equinor



During the webinar the experts answered a series of policy technical and safety questions from the audience. The webinar started with a poll to get a sense of which sectors attendees saw hydrogen playing a key role in 2040 - 77% chose industrial processes 54% mobility and 31% power generation. The questions ranged from the opportunities and limitations of blending hydrogen with natural gas to safety concerns surrounding hydrogen.



KEY HIGHLIGHTS:

How much hydrogen can be blended with natural gas depends on the rules and regulation of each country. The general consensus is that blending 10% by volume of hydrogen presents no safety concerns or specific difficulties. This would provide an opportunity to develop low hydrogen markets. Nevertheless blending should not be the end destination. It is not sufficient to meet carbon abatement targets.



Low carbon ammonia has a role to play in the new hydrogen economy. It is a proven and understood technology which is easier to move around the world and could be used directly as ammonia or cracked back into hydrogen.



One of the main focus today should be to replace grey hydrogen with green hydrogen in existing supply chains as there would be no efficiency losses in the process.



In China the push for hydrogen is transport-related. This is driven by air quality and energy independence concerns. In the next 10 years the full life cost of fuel cell electric vehicles (FCEVs) is expected to be lower than for internal combustion engines. This is due to the fact that FCEVs require less maintenance and that the residual value in the fuel cells is relatively high. At the end of life 95% of the platinum in fuel cells can be repurposed.



FCEVs should not be regarded as competing with battery electric vehicles they sit next to each other on product maps. FCEVs can benefit from the all of the advances in electric drive train systems and electric motors.



To close the webinar attendees were asked whether hydrogen was going through another hype cycle or if it was here to stay. 10% answered hype and 90% here to stay.

Policy led decisions aiming at decarbonizing the economy may well exacerbate existing regional economic imbalances. These effects are seldomly recognised in spatially aggregated top-down and techno-economic decarbonization strategies. Here we present a spatial economic framework that quantifies the gross value added associated with low carbon hydrogen investments while accounting for region-specific factors such as the industrial specialization of regions their relative size and their economic interdependencies. In our case study which uses low carbon hydrogen produced via autothermal reforming combined with carbon capture and storage to decarbonize the energy intensive industries in Europe and in the UK we demonstrate that interregional economic interdependencies drive the overall economic benefits of the decarbonization. Policies intended to concurrently transition to net zero and address existing regional imbalances as in the case of the UK Industrial Decarbonization Challenge should take these local factors into account.

This Insight provides an overview of the recent EU Commission Hydrogen Strategy Energy System Integration Strategy and Industrial Strategy focusing on regulatory issues impacting hydrogen. It looks at the proposed classification and preferences for different sources of hydrogen financial and regulatory support for development of hydrogen supply demand and infrastructure as well as potential regulation of hydrogen markets. Whilst the Hydrogen Strategy underlines the need for hydrogen to decarbonise the economy the Insight concludes that the EU has shown a clear preference for hydrogen based on renewable electricity at the expense of low carbon hydrogen from natural gas even though it recognises the need for low carbon hydrogen. In addition further detail is required on the support mechanisms and regulatory framework if development of new hydrogen value chain is to succeed. Lastly there is little sign that the Commission recognises the change in regulatory approach from the current natural gas framework which will be needed because of the different challenges facing the development of a hydrogen market.

This latest report describes the potential for CCUS as an important technology during the UK’s energy transition and focuses on the role that metrology (the science of measurement) could play in supporting its deployment. High priority measurement needs and challenges identified within this report include:

• Measuring and comparing the efficiency of different capture techniques and configurations to provide confidence in investments into technologies;
• Improving equations of state to support the development of accurate models used for controlling operational conditions;
• Improving CO₂ flow measurement to support fiscal and financial metering as well as process control and;
• Improving the understanding and validation of dispersion models for emitted CO₂ including plume migration to support safety assessment.

The European Union (EU) has adopted ambitious decarbonization targets for 2050.

Renewable electricity and electrification are the key drivers but are not sufficient on their own to meet the targets. A number of countries expect decarbonized gas (e.g. renewable hydrogen and biomethane) to be part of a future decarbonized energy system.

Within that context this paper examines proposals recently issued by Spain’s energy regulator (CNMC) to define the methodology for remunerating gas distribution and transmission networks and LNG regasification terminals. Their proposals would reduce significantly the remuneration of these activities. Bearing in mind the objective of decarbonization this paper analyzes key features of the proposals and concludes with recommendations. We suggest:

• Adoption of a common methodology for remunerating new investment in gas and electricity infrastructure assets. The Regulatory Asset Base (RAB) approach is a suitable methodology especially for high-risk investment to integrate hydrogen.
• CNMC reconsideration of its proposals for existing assets. The aim should be to ensure that even if remuneration is reduced to some extent investors will still be compensated adequately and that the companies will continue to support the investments needed to digitalize processes deliver natural gas and eventually deliver renewable gas where it is economic to do so. This is an important signal for current and future investors whose investments will be regulated by the CNMC.
• Clarification of the methodology for remunerating renewable gas facilities. If renewable gas (especially hydrogen) requires access to regulated gas networks the CNMC methodology must provide suitable incentives to invest in network expansion and upgrading as required as well as to maintain natural gas operations. Even if no decision is made in the short-term regarding hydrogen it would be prudent to leave the door open by making the regulation compatible with future decisions involving hydrogen development.
• Consideration of potentially stranded assets. The CNMC and the Government should coordinate over the remuneration of infrastructure assets when national policy decisions may lead to the stranding of these assets.
• Decarbonization of the energy system as a whole. The CNMC and the Government should consider how best to promote the decarbonization of the energy system as a whole rather than its individual parts and what role is to be played by regulated networks and by unregulated initiatives in competitive markets especially for the development of hydrogen systems.

The Hy4Heat Safety Assessment has focused on assessing the safe use of hydrogen gas in certain types of domestic properties and buildings. The summary reports (the Precis and the Safety Assessment Conclusions Report) bring together all the findings of the work and should be looked to for context by all readers. The technical reports should be read in conjunction with the summary reports. While the summary reports are made as accessible as possible for general readers the technical reports may be most accessible for readers with a degree of technical subject matter understanding. All of the safety assessment reports have now been reviewed by the HSE.<br/><br/>A comparative risk assessment of natural gas versus hydrogen gas including a quantitative risk assessment; and identification of control measures to reduce risk and manage hydrogen gas safety for a community demonstration.

Iridium-containing NaTaO₃ is produced using a one-step hydrothermal crystallisation from Ta₂O₅ and IrCl₃ in an aqueous solution of 10 M NaOH in 40 vol% H₂O₂ heated at 240 °C. Although a nominal replacement of 50% of Ta by Ir was attempted the amount of Ir included in the perovskite oxide was only up to 15 mol%. The materials are formed as crystalline powders comprising cube-shaped crystallites around 100 nm in edge length as seen by scanning transmission electron microscopy. Energy dispersive X-ray mapping shows an even dispersion of Ir through the crystallites. Profile fitting of powder X-ray diffraction (XRD) shows expanded unit cell volumes (orthorhombic space group Pbnm) compared to the parent NaTaO₃ while XANES spectroscopy at the Ir LIII-edge reveals that the highest Ir-content materials contain Ir⁴⁺. The inclusion of Ir⁴⁺ into the perovskite by replacement of Ta⁵⁺ implies the presence of charge-balancing defects and upon heat treatment the iridium is extruded from the perovskite at around 600 °C in air with the presence of metallic iridium seen by in situ powder XRD. The highest Ir-content material was loaded with Pt and examined for photocatalytic evolution of H₂ from aqueous methanol. Compared to the parent NaTaO₃ the Ir-substituted material shows a more than ten-fold enhancement of hydrogen yield with a significant proportion ascribed to visible light absorption.

Evidence-based policy-making has been a much-debated concept. This paper builds on various insights for a novel perspective: policy-driven narrative-based evidence gathering. In a case study of UK priority setting for bioenergy innovation documents and interviews were analysed to identify links between diagnoses of the problem societal visions policy narratives and evidence gathering. This process is illuminated by the theoretical concept of sociotechnical imaginaries—technoscientific projects which the state should promote for a feasible desirable future. Results suggest that evidence has been selectively generated and gathered within a specific future vision whereby bioenergy largely provides an input-substitute within the incumbent centralised infrastructure. Such evidence is attributed to an external expertise thus helping to legitimise the policy framework. Evidence has helped to substantiate policy commitments to expand bioenergy. The dominant narrative has been reinforced by the government’s multi-stakeholder consultation favouring the incumbent industry and by incentive structures for industry co-investment.
