Which gases causes Global Warming?

Where do CO2 emissions come from?

What % of heating is not 2050 Ready?

What % of heating is not 2050 Ready?

Where do we do heating in Scotland? (note total demand circa 78,000 GWh ~ 2bn £GBP

2km strip astride the river = 4209GWh /a

How much heat is in a river?
20,000 l/s
If cooled by 3K
= 0.2508 GW
If harvested 8760
hours per year
= 2197 GWh/a

What % of heating is not 2050 Ready?

CASE STUDY: DISTRICT HEATING
DRAMMEN (the original success in 2010)
• District heating system in Drammen, Norway
• 13.2MW water sourced heat pump
• High temp (90oC) water generated from 8oC fjord
• Proves 85% of hot water needed to heat the city
• World’s largest 90oC ammonia heat pump
• Average COP of 3.05 (over 8 years running)
• Renewable energy source
• Fully natural refrigerant
• Easily repeatable technology

CASE STUDY: DISTRICT HEATING-Queen Quay-2019 Commissioning
• 5.2MW river water sourced heat pump
• High temp (80oC) water generated
from 5oC river
• UK’s largest 80oC ammonia heat pump
• Typical COP of 3
• CO2 circa 45% of Gas and falling
• Zero Local NOx

CASE STUDY: DISTRICT HEATING-Queen Quay – UK’s Largest HT River Heat Pump
• Harnesses local energy
• Doesn’t create NOx (clean air)
• Creates local jobs
• Allows more wind generation
• Produces Cooling as well
• Can use cheapest tariff
• 3 units heat for 1 unit electricity
• 2050 Ready!

So- the opportunity?
What makes

happen?Over & Over

What makes District Energy happen over & over?
Low Risk
Predictable
Repeatable
R.O.I.

So- the opportunity?
• Harness local energy from rivers
• (low risk capital as rivers are known)
• Purchase off peak electricity – use thermal
stores @1/1000th cost of LI-ion batteries
• Generate and distribute heating and cooling

Barriers?
• Customers are happy with gas
• District heat is seen as tricky and a by-product
of CHP which is struggling as electrical tariffs
are up and down like a yo-yo

Solution -> Thinking really big! An end to end energy solution – part1
• Work with cities to create a concession zone
• Work with cities to educate around NOx / CO2
• Set NOx/CO2 phase down targets 3% per year
• Issue improvement notice if 9% behind OR
•Join DH; setup as a “fairopoly”

Solution -> Thinking really big! An end to end energy solution – part2
• With improvement notices avoided in favour of DH…
• Plan DH routes and demands
• On a big scale bring private wire power @ <€60/MWh
• Build your own -> with guaranteed consumers – you!
•Build the new paradigm of energy

So the three keys to clean cities
Secure Customers -> FAIROPOLY
Secure Costs –> Private Wire Wind
Secure Technology-> RSHP + DH

Things I’d do in an Emergency………..Commercial Users
• Remove all taxation from clean heat – keep nonDom RHI for HP
• Add all lost taxation onto dirty heat (incl gas)
• Ramp up CCL (per kgCO2 per fuel)
• So Commercial customers only for first 5 years
• Compel commercial users to 3%/a or agree to DH-FAIROPOLY
• Define FAIROPOLY- Price 5p/kWh, cleanliness <120g/kWh @2020
• Auction DH zones (p/kWh fee) – linear strips from river
• Or from Key Heat emitters (but watch durability of fuel)
• Start Running towards the problems- not away from them.

Things I’d do in an Emergency………..Domestic
• Remove all taxation from clean heat
• Announce intention to add taxation onto dirty heat (incl gas)
• Outline CCL (per kgCO2 per fuel) starting 2025 – gas only!!
• So Commercial customers only for first 5 years
• Continue domRHI – it would have worked with PAYG from 2008!
• Force BIG5 to offer domestic GSHPs (pay as you go : 10% below gas)
• Allow replacement gas boilers on rental only (electric only?)
• Be much clearer about H2 opportunities – it isn’t really for heat.

Run towards the Emergency and take action like Alex McIlveen
