Lesson 13: Radical Technologies Flashcards
Define radical technologies
New approaches using state of the art technology which aim to reduce carbon emissions in the near future
Give some examples of radical technologies
Carbon storage, carbon capture, hydrogen fuel, electric cars
What are the benefits of using hydrogen fuel cells?
-It’s not going to run out
-Produces no pollution – if renewables are used
-Could reduce dependence on fossil fuels for transport
What are some of the negatives of hydrogen fuel cells?
-Requires a large amount of energy to separate elements
-Water vapour is considered a greenhouse gas, so an increase in water vapour could lead to an increase in temperatures
-Fossil fuels may be needed to separate the different elements
Which company developed a car which could travel 270 miles on hydrogen fuel, and went on sale in 2015?
Toyota
Which organisation has used liquid hydrogen since the 1970s?
NASA
What are the benefits of electric vehicles?
-Cheaper to run than a petrol/diesel car
-Produces no pollution
-Could reduce dependence on fossil fuels for transport
-Massively reduced noise pollution compared to a petrol/diesel car
What are the negatives of electric vehicles?
-Expensive to buy due to the technology
-Charging times are improving but can take a while for a full charge
-The quietness could be a hazard to pedestrians
-The ‘greenness’ of an electric vehicle depends on the energy profile of the country e.g. using renewables or non-renewables for charging
What was the world’s best selling electric vehicle between 2018-19? What distance could it go?
Tesla Model 3
310 miles
How many public charging locations were there in 2016, for how many vehicles?
3919 for 60 000 vehicles
What % of these charging points were in London compared to Wales?
20% in London
3% in Wales
How much could CCS cut CO2 emissions by?
19%
Where was the first coal-fired power station opened in 2014? How much did it cost?
Canada
US$1.3 billion
How much did this CCS plant cut emissions by?
90%
How much carbon has Shell’s carbon capture project ‘Quest’ sequestered?
4 million tons
