Q1: Since 90s the UK has achieved great success in modernising the power sector, reducing waste and decarbonising industrial processes. This success must be replicated in heating if we are to meet our climate targets. Out of 468 Mt of CO2e emitted in the UK in 2016, how much was contributed by Heat?

18 %

26 %

37 %

49 %

Q2: It is essential that heating demands must be met by low-carbon energy sources of energy. For instance, in Norway 80% of residential and commercial heating are electrified and in Latvia the demand is partially (40%) met by biofuels and waste. How many households use natural gas for heating in the UK?

23 %

42 %

68 %

85 %

Q3: Unlike decarbonisation of the power sector, heating decarbonisation at scale will have a direct impact on consumers. How many electrical heat pumps is projected to be installed in UK homes in 2050 (assuming net-zero scenario)?

8 mil.

19 mil.

27 mil.

35 mil.

Q4: In addition to low carbon sources, heat networks play a key role in decarbonising heat. What is a heat network?

A. Heat networks are systems of insulated pipes that take heating or cooling from a central source and deliver it to customers

B. Heat networks are pipeline networks designed for supplying biogas to customers for heating purposes

C. Heat networks are electricity distribution systems that deliver electricity to heat pumps in residential buildings

Q5: One of the most promising decarbonisation approach is defossilisation of gas grids by using hydrogen admixture. European countries have already formed their hydrogen strategies based on the blending volumes with allowable limits being 6% in France and 12% in the Netherlands. What is the corresponding limit in the UK?

0.01 %

0.5 %

2 %

5 %

Q6: Hydrogen accounts for less than 2% of Europe’s present energy consumption and is primarily used for chemical production. 96% of Europe’s hydrogen is produced by fossil fuels, emitting significant amounts of CO2 and is named “brown hydrogen”. What is the name of low-carbon hydrogen produced from natural gas with carbon capture?

Purple Hydrogen

Green Hydrogen

White Hydrogen

Blue Hydrogen

Q7: Aluminium industry emits 1.1 billion tons of CO2 equivalent annually. China, the world’s largest producer, accounts for more than half of the total aluminium output (36 Mt in 2019) with emissions being one of the largest in the world – 14.8 tons of CO2 per ton of the metal produced. This is due to electrolysis (77 % of the life-cycle emissions), the most energy-intensive step being powered by carbon-heavy sources, primarily, coal. What would the reduction in emissions from aluminium industry be if the power supplied to production facilities in China came from renewable energy sources (RES)? Assume the energy consumption during electrolysis to be the only source of emissions and RES to be carbon neutral. Provide the answer in %, round it to the closest integer.

Q8: According to Ten Point Plan for a Green Industrial Revolution, we will see 1GW of floating wind capacity installed by 2030. The UK has pioneered the technology in 2017 by becoming home to the first commercial floating wind farm. What is the name of this project?

Dodger Bank

Hornsea One

Hywind Scotland

Thanet

Q9: In the past decade renewables have taken a huge leap forward in terms of improving cost-efficiency. Wind and solar are now roughly 45 £ per MWh (offshore wind is slightly more expensive – 57 £ per MWh). In addition to cost, the load factor I.e., the %annual net available energy also determines the feasibility of the project. In the UK the load factor for onshore wind generation is 34%. What is the corresponding figure for solar PV technology?

11 %

20 %

27 %

35 %

Q10: Power mix in the UK is notably versatile. On a good day it is comprised of various renewables like solar, hydro and wind complemented with storage, conventional energy carriers, predominantly gas, and other sources like biomass. On a bad day: when the winds are not blowing and the sun is not shining, coal-fired power plants are switched on to account for the imbalance between demand and supply. In 2020, partly because of the coronavirus lockdown, the UK has broken its coal-free power record. How long did this run last?

19 days

38 days

51 days

67 days

Q11: Coal is the most carbon intensive fossil fuel, producing around twice the carbon dioxide (CO2) per unit of electricity as natural gas. The UK Government recognizes its impact and has recently announced the intensions to bring forward the ban of unabated coal generation to 2024. Which year was proposed by previous legislation?

2025

2027

2028

2030

Q12: In times of high demand, when environmentally friendly options become too expensive, electricity is imported to the grid through interconnectors with other countries. Which country does the UK import from the most?

Norway

The Netherlands

Ireland

France
