Energy in Cardiff:Technology and Innovation in the

Public Estate

Gareth HarcombeEnergy and Sustainability Manager

• Cardiff’s Energy Challenges• Progress to date• Ambitions for the future

• The Innovation Story• How and why• Benefits and barriers• What next?

OUTLINE:

Fastest growing UK city –30,000 new homes, 40,000 jobs

Carbon reduction targets - local, national and international

Liveable City ambitions and Future Generations Act

Affordability and security of supply- fuel poverty- local business and inward investment- transportation

£10m annual energy bill for Council buildings

Cardiff’s Energy Challenge

Installed energy efficiency measures in 50 schools and Council buildings

Installed energy efficiency measures in nearly 2000 homes (ARBED/ECO)

Bill Validation and Automatic Meter Reading Incl “Carbon Culture”

Behaviour change strategies (inc remote management)

Re:Fit Cymru - £2m 16/17

Cyd Cymru Energy Switching Scheme

Energy Management and Retrofit

Radyr Weir Hydro - 0.4MW

Roof Mounted Solar (Estate)- 0.74 MW

Roof Mounted Solar (Residential) -100 schemes

Viridor Energy From Waste - 30MW (+20MW heat?)

Celda AD plant (Under const.) – 1.5MW (+1MW heat?)

Landfill Gas 4MW

Misc biomass/Ground Source/Air Source/Solar HW

RENEWABLES @ 36MW

 6% reduction in carbon emissions in Council Estate 15/16  16% of Cardiff’s per-head electricity consumption from local renewable sources, (4th highest urban area in England & Wales (Green Alliance City League Table 2015))  35% decrease in per capita carbon emissions 2005/2014(DEIS/DECC Carbon Dioxide Emissions statistics for 2016). 2020 EU Covenant of Mayors target met (reduce per capita CO2 emissions by 26% by 2020)

OUTCOMES:

Left to do?

Left to do?

Left to do?

Energy Innovation – Why bother?Austerity

Mainstream funding = requires “invest to save” business cases

Carbon Reduction targets remain

Working collaboratively to solve unanswered questions

Engaging with local academia, R&D and entrepreneurship

Councils can offer:• A host of problems to be solved• Large estates to enable prototyping and demonstration• Market exposure and promotion• Strict compliance frameworks!

Support, Funding and De-risking

Energy Innovation – How?

Aspiration/problem

Partner conversation

Project development

Consortium building

Funding opportunity

PROJECT BID£€

Grant funding to support a “leap of faith”

Projects:• Small Business Research Initiative (SBRI)

– “Pre-commercial procurement”

• Energy Catylist– Innovation support

• EU FP7/Horizon 2020– Member state collaboration for innovation

Heritage Retrofit SBRIThe “problem”• More than 30% of buildings in Wales are over 100 years old• Mainstream retrofit sometimes conflicts with heritage protection£500k to run an SBRI Competition for new solutions• 30 applicants, 6 feasibility projects, 3 demonstrators

Q-Bot Limited Underfloor Insulation Robot

Okotech Ltd Heatboss® wireless zoned heating control solution.

Vivus LimeQuick drying lime render and insulation panels

Wasted expenditure

Unrealised energy

Failure Demand

Portable Renewables SBRIThe “problem”• Vacant and underused land• Not enough renewable generation in cities• Can energy be a temporary “meanwhile” use?

£1m to run an SBRI Competition• 35 applicants, 4 feasibility projects, 2 demonstrators

Solar ROLLARAY with storage

Trailblazer Flexible solar sheets with storage

GROUNDWATER HEAT PROJECT

£260k grant for collaboration project

GROUNDWATER HEAT PROJECT

• Grangetown Nursery School Heat pump• Sensors and impact monitoring in 60 boreholes• 3D city scale geological mapping and heat model

Hydrogen Enabled Local Energy

EU FP7 PERFORMERPortable, Exhaustive, reliable, Flexible and Optimized appRoach to Monitoring and Evaluation of building eneRgy performance

• Understand why building actual energy performance is different to building predicted energy performance

• Look to reduce this gap by better management of the buildings HVAC systems through ICT controls

EU FP7 WISDOMWater analytics and Intelligent Sensing for Demand Optimised Management

Demand Management

(Behaviour Change)

Outcomes• 9 live projects• £2.2m external funding and 30 partners• 9 first-of-a-kind technologies/processes being

demonstrated in Cardiff’s estate

• Progress in austerity• Carbon reduction and energy savings• Economic development and SME support

But…

• Dependent on external funding• Fiercely competitive• Opportunistic• Difficulty to be strategic• LA’s not “on the circuit”• Funding rules sometimes prohibitive• EU funding future

Next Steps:• A more strategic approach?

• A network of potential collaborators?

• Broad target areas:• Heat• System integration• Smart energy management• Smart cities

• Moving from demonstration to market (the “valley of death”)?

• Keeping the conversation live?
