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?
