The UK
government this week launched its ten point plan for a future greener economy.
The name ‘Green Industrial Revolution' is a straight lift from the Labour party’s
manifesto at last year’s general election, but differs in some ways. This is a
summary of the report with analysis which can be downloaded
here.
Point 1:
Advancing Offshore Wind
The report says
that by 2030, we aim to produce 40GW of offshore wind, including 1GW of
innovative floating offshore wind. It goes on to say that this could encourage
private investment of £20 billion coming into the UK. Aurora Energy Research
(AER), an Oxford-based consultancy, have calculated the UK would need to increase
the UK’s offshore wind power capacity by
four times what it is today, to reach 40GW by 2030, and cost around £50
billion. On the face, it means the government would need to meet the other £30 billion, which is ambitious
given demands on the public purse at present.
This would
provide enough ‘power’ for every home in the UK, but it is not clear whether
this includes heating, but I don’t think it does, because domestic electricity demand
is about a quarter
of all energy used in the UK. So, a four-fold increase in offshore wind
power suggested by AER, seems not to cover natural gas, which is the main
source of heat in UK homes.
Point 2:
Driving the Growth of Low Carbon Hydrogen
Working
alongside partners in industry, our aim is for the UK to develop 5GW of low carbon
hydrogen production capacity by 2030,
says the report. 5GW is a fairly modest amount of energy, but when I first read the
Prime Minister’s piece written for the Financial
Times (subscription), where he wrote of producing hydrogen from water, I thought this
was about electrolysis. Passing electricity through water is one way of
producing hydrogen, but only accounts for about 2-3% of hydrogen produced, the
vast majority of which is made from fossil fuels.
There is mention
of producing hydrogen by electrolysis in the report, but also of producing low
carbon hydrogen at scale will be made possible by carbon capture and storage
infrastructure. More on this later, but on producing hydrogen from water,
there is a major drawback.
The process of producing
hydrogen this way consumes approximately 50 to 55 kilowatt-hours of electricity
per kilogram of hydrogen produced, so is a very inefficient and expensive way
of producing hydrogen. Presumably the plan is for the electricity to be from renewable
sources, but later in the report carbon capture and storage from fossil fuels is admitted. To upscale this type of production from renewable sources would put massive demand on renewables, of which most seems destined for
domestic use. Nuclear power also comes into the mix later in the report.
There is also
mention in this section of ground heat pump technology, which is quite feasible
and should have been encouraged years ago.
Point 3:
Delivering New and Advanced Nuclear Power
In this section
the report says we are announcing up to £385 million in an Advanced Nuclear
Fund. This will enable investment of up to £215 million into Small Modular
Reactors to develop a domestic smaller-scale power plant technology design.
The processes for mining and refining uranium ore and making reactor fuel all
require large amounts of energy. Nuclear power plants also have large amounts
of metal and concrete, which require large amounts of energy to manufacture, so
are not carbon free, although to a lesser degree, you could say the same about
wind and solar power.
There are of
course problems with nuclear power, the radioactive toxic waste which is only
any use for nuclear weapons, which in itself makes it undesirable, but if
stored is prone to leak. We’ve seen a few accidents at plants releasing
radiation into the atmosphere and there is also the possibility of terrorist
attacks, perhaps increased by lots of smaller plants. They tend to be situated in
coastal regions for cooling purposes, but this is risky if the seas rise, if plans
like this do not limit global warming. Nuclear plants are very expensive too,
with the government intended investment looking quite puny.
Point 4:
Accelerating the Shift to Zero Emission Vehicles
This section announces
the banning of sales of petrol and diesel cars and vans from 2030, and that
from 2035 only electrically powered (and hybrid) cars and vans will be allowed on
the UK’s roads. A consultation will take place on replacing heavy goods trucks.
There will be an acceleration in the provision of roadside charging points.
This is good
news for air quality in the UK, but the electricity to power these vehicles
will need to be produced somewhere, somehow, and it looks likely that this will
be produced by nuclear power or fossil fuel burning, although the report does not say that specifically. This will
require a huge amount of power, and it is unlikely that this will be able to be
provided by wind power, or other renewable energy sources.
Point 5: Green Public Transport, Cycling
and Walking
The report
promises we will invest tens of billions of pounds in enhancements and
renewals of the rail network, £4.2 billion in city public transport and £5
billion on buses, cycling and walking. Some rail links removed in the
Beeching era (post second World War) will be restored as well as new rail links
between towns and cities, and bring the level of public transport within cities up
to the level of London, which is ahead of the rest of the country.
All welcome
again, but there is no specific mention of how these trains and buses will be powered, so again it looks as though this will
provided by nuclear power and fossil fuels. Walking and cycling of course needs no external power,
and is uncontroversial.
Point 6: Jet
Zero and Green Ships
The 5GW of
power produced by hydrogen mentioned in Point 2, will clearly not be enough the
power all civil aeroplanes and shipping, and military craft are not mentioned
at all. The report also mentions electric power, but especially with aircraft
batteries, they will need to be so large that the number of passengers on flights will need
to be dramatically reduced, making them non cost effective.
Again it looks
like if this to have any success, we will be relying nuclear power or fossil fuels. Why there
is no mention of that old, tried and trusted method of powering ships, wind, is
perplexing? Some ships already use sails in a kind of hybrid system, together
with a conventional engine, for when the wind drops.
The report also says that blending ‘greener’ fuels into kerosene, which I take to mean
biofuel, produced from vegetable oil or the like. This is certainly feasible
but as always with biofuels they compete for land with food production and forestation. There is
only so much land to go around.
Point 7:
Greener Buildings
The government
will ‘aim’ for the installation of ground heat pump technology of 600,000 units a
year up until 2028, but also leaves open the possibility of providing hydrogen or
electrical heating to supplement heat pump supplied heating. Building energy efficiency,
with better insulation of buildings (homes and other buildings) also features
here, but the Green Homes Grant will only be extended by one year.
Other than
hydrogen or electrically produced heating, as mentioned previously, and carbon
capture and storage, this is easily achievable, and should have been done
before now.
Point 8:
Investing in Carbon Capture, Usage and Storage
The report says that the ‘ambition’ is to capture the equivalent of four million cars’ worth of annual emissions, and store it underground. There will be four sites, in Scotland, Wales, the north west and north east of England, but nothing in the south of England. The plan is to use redundant North Sea oil wells as well for the storage of the CO₂. This is not a huge ambition, given that carbon emitting energy will need to be used to implement the rest of this plan, but is perhaps mindful that this technology has not been deployed on a largescale anywhere in the world.
The technology
can capture up to 90% of CO₂ emitted by burning fossil or biofuels. According
to the Global
CCS Institute’s 2019 Status Report, 40 million metric tons of CO₂ from plants currently in operation or
construction are captured and stored each year. So, the UK government target
for capturing 10 million metric tons, equates to a quarter of what exists in
the whole world at present, but is still modest compared with what will be needed.
Carbon capture
and storage (CCS) is expensive. A plant with CCS uses more fuel than one without, to
extract, pump and compress the CO2, as well. There is also the
problem of leakage, from the wells, but more so from pipelines that transport
the emissions. The most extreme sudden CO₂ release on record took place in
1986 at Lake
Nyos, which is a lake naturally saturated with carbon dioxide, in Cameroon. It suffocated 1,746 people within 25 kilometres of the lake.
In a paper
looking at what role negative emissions should play in meeting the Paris goals,
the European
Academies’ Science Advisory Council, a group made up of all the different
national scientific academies in European Union (EU) member states, concluded that the technologies
“offer only limited realistic potential to remove carbon from the atmosphere
and not at the scale envisaged in some climate scenarios”.
Point 9:
Protecting Our Natural Environment
This section is
mainly about planting more trees, for natural carbon capture and building more
flood defences. The aim is that 30,000
hectares of new forests a year will be planted.
The 30,000-hectares
figure was laid out by the UK government’s Committee on Climate Change in its net-zero
report, which it said equated to planting between 90-120m trees per year.
It concluded increasing forest cover to “at least 17%” of the UK’s land area, together with improved woodland management, that would sequester an additional 14 metric tonnes of CO₂ each year. This figure is based on planting 30,000 hectares annually from 2024.
17% is a big
ask for a small overcrowded country like England, so I would expect most of
this activity will take place in Scotland and Wales. Estimates vary as to how
effective this will be at removing carbon from the atmosphere, but tend to be
calculated using mature trees as the model, which obviously take years to grow
to that stage.
Point 10:
Green Finance and Innovation
This final
section of the report focuses on research and development into the other nine
points of the plan and will be backed by a £1 billion public investment
portfolio. Private investment will be sought by the issuing of a Sovereign
Green Bond next year (subject to market conditions).
In a specific
mention the report says that the UK aims to be the first country to commercialise
fusion energy technology. This technology produces power by using heat from nuclear fusion
reactions to produce electricity and can be used to produce hydrogen. Research
into fusion reactors began in the 1940s, but to date, no
design has produced more fusion power output than the electrical power input,
rather defeating the purpose of the exercise.
There is also
mention of the City of London exploiting ‘carbon markets’ where emissions are
traded around, making a nice profit for the traders, but not reducing emissions
significantly, as with EU’s scheme, which is more advanced than any other in the world.
Why now?
The COP26
meeting on climate change will be held in the UK, Glasgow, next November, so this report is aimed at providing the UK with some kind of leadership role at the summit. It
is also noticeable that the Prime Minister, Boris Johnson, has quickly changed
horses, after President-Elect Joe Biden’s election win in the US. Johnson was
one Donald Trump’s strongest supporters among world leaders, and had little to
say against Trump’s climate change denying rhetoric and actions while he was
president. The release of this report now is not a coincidence, since the US
will probably adopt something similar to this plan.
Some notable
omissions from the report are worth mentioning. No mention
of banning fracking, when we know that we cannot even burn all of what is left
of conventional fossil fuels on the planet. No mention of hydro or wave power,
which has potential, particularly wave power for the UK. No mention of future
rising demand for energy, which there surely will be. Just one example from the
UK is that a space port is planned to be built in Scotland.
This plan is
broadly in line with the commitments made by the UK, and other nations at the
COP21 meeting in Paris in 2015. The idea of making that agreement was that it would, by and large, allow the world to carry with business as usual. The growth
that is required by our economic system, capitalism, needs every increasing
levels of energy to power it, so that high levels of economic growth can be
maintained. Without this, the system will fall into recession, depression and ultimately
die. It is not sustainable, to use an ecological term, but the type of techo-fixes
suggested in the UK government’s plan allow for a pretence that it can be.
There are some sensible measures suggested, things that could have been done many years ago, but don’t be fooled that this will improve our chances of limiting a temperature rise to below 1.5C of pre-industrial levels, which COP21 was meant to achieve. But that was never likely to be met by these type of measures anyway.
Is there a mention of air heat pumps as they are much cheaper?
