The Delta-EE European Heat Summit 2019

The Bloomsbury Hotel, London
25-26 September 2019
The Delta-EE European Heat Summit for 2019 took place on 25-26 September 2019.
This invitation-only event brought together key players to discuss the latest developments and expectations for the future of heat in Europe. Our key themes this year were decarbonisation, disruption to heat business models, flexibility, and hydrogen. To find out more about the issues discussed, you can read our blog post here.

For further information on our 2020 event, please contact directly.

09:00 - 09:30


1. Opening, scene setting - Decarbonisation and the transition to new heat


The European heating market is seeing greater disruption than ever before as it transitions from old heat to new heat – decarbonisation policy is tightening, new technology ecosystems are emerging, new competition is threatening the incumbent heating players, and the traditional heat sales channels and customer propositions are being shaken up.  We will set the scene, exploring how decarbonisation pathways for heat are evolving in Europe, in the context of this transition.

2a. Disruption to heat business models: From kWh to comfort


Traditional heat business models are evolving beyond just selling kWh. New customer propositions such as Heat-as-a-Service are emerging which promise to erode customer barriers to the uptake of low carbon heating. Digitalisation and connectivity is bringing more information – and potentially decision-making power – to the customer.  Since last year, we see a step change in how this disruption is evolving – from trials and pilots to real commercial projects. In this session, we will focus on the evolution of customer propositions - who will be the winners in the future heating market, and with what propositions?

2b. Disruption to heat business models: From shifting boxes to selling services


Heat business models are moving beyond shifting boxes towards service-based offerings. New routes to market such as online sales platforms are increasingly threatening the traditional sales channels.  Emerging, innovative concepts to achieve mass building retrofit are making inroads in some markets.  In this session, we will focus on route-to-market disruptions – how will heating products and services be sold in future, and who will the key stakeholders be?

3. Innovations in new heat 


The transition to new heat is driving innovation, aiming to tackle retrofit, move closer to zero carbon new build, and capture value for customers and market stakeholders.  We will be joined by key technology manufacturers & solutions providers to share highlights of the latest innovation emerging to supportthe transition from old heat to new heat.

4. Electrification of heat and decarbonising the electricity system: Opportunities from sector coupling


As the electricity sector decarbonises, the need for energy system flexibility is rising.  For electric heating (and cooling) products, the ability to control the timing of demand is becoming more important than the amount of demand.  Business models utilising the flexible operation of residential electric heating products are beginning to move from the trial stage to commercial reality in some markets, potentially creating value for customers, networks, energy suppliers and new entrants.  Gas players are engaging too, seeing the potential to contribute to the flexibility of the whole energy system.  We will explore the outlook for those trying to capture value from this flexibility, and discuss the activities (and successes) of a range of players.

5. Hydrogen for heat: Hype, hope or a silver bullet?


Hydrogen is a hot topic with policy-makers in many markets at the moment, not least for its potential role in decarbonising gas. It is clear that hydrogen will be a part of the future energy system – though “hydrogen for heat” is moving forward at very different rates in different markets, with some uncertainties remaining about how it will be used.  Some manufacturers have already jumped ahead of the curve, launching hydrogen boilers and fuel cells, and others point to the potential for “hydrogen hybrids”. We will explore in this session, how hydrogen for heat is evolving in key markets, how it could interplay with other energy vectors, and what the impact could be on the heating market.

10:45 - 11:00 Arrival, registration, coffee
11:00 - 12:00 Technology Perspective: Delta-EE's top 5 sweet spots in 'new heat' Decarbonisation is driving a shift in heating technology towards being more efficient, more connected and more integrated. We will present Delta-EE's view of 2019's top 5 opportunities in 'new heat' technologies. We will then welcome subscribers' Q&A, views and input to the roundtable discussion.
12:00 - 13:15 Lunch  
13:15 - 14:00 New heat customer propositions: How to bring the customer with you Customers of the future will be more informed, more active and more powerful in decision-making about heat. What does this mean for the heating industry? We will present highlights from our own customer research and market insight, then welcome subscribers' Q&A, views and input to the roundtable discussion.
14:00 - 14:45 New heat routes to market: The evolving role of the heating installer The traditional two-tier route to market may no longer dominate in the future, as focus on services (and not only products) brings new competition and shifting roles of key stakeholders.
