If cutting greenhouse gas emissions is as important as is claimed, there are two main ways to do it: stop using fossil fuels as soon as possible, or continue to burn them while viable alternative energy sources are developed, and remove and lock up the resulting carbon dioxide. Carbon Capture and Storage (CCS) still has its supporters, despite a singular failure to upscale in any way that could be easily rolled out on the vast scale needed. But, if – and it’s a big if – a recent report is true, then this outlook could change. The report on the Independent website certainly hypes up one...

Consumer prices for gas and electricity have to cover various fixed costs – the distribution network, maintenance, metering, administration etc – but are determined primarily by market prices for fuel. With oil, coal and gas prices being relatively low, Europeans should normally be looking forward to a period of stable or even falling utility bills. However, climate change policy has changed this situation. By requiring suppliers to generate increasing proportions of electricity from renewables – wind in particular – and by effectively taxing the use of fossil fuels, prices are being...

The old adage that good news isn’t really news today seems truer than ever. Bad news is reported rapidly across the internet and social media, and there are unfortunately relatively few good news stories that command as much attention. Something such as the Olympics is the exception. But it’s not just current news that is generally bad; increasingly we see dire predictions about the future. In fact, perhaps this has always been the case. After all, think how much science fiction envisages a dystopian future. Computer modelling, which is the source of most of the current stories, uses...

It seems that the UK’s first new nuclear power station for a generation – Hinkley Point C – will finally be built (Hinkley Point C finally gets green light as government approves deal with EDF and China). The deal has been widely criticised, but it still has its supporters. So, at this critical stage, it is worth trying to put this key part of the country’s future energy infrastructure into context. With the benefit of hindsight, it is probably not something that any of the parties involved would want to start from scratch now. But we are where we are, and the project has to be viewed in...

Carbon Capture and Storage (CCS) sounds simple, but is very complex to put into effect. But it remains a potentially attractive policy option for one key reason: its successful introduction would allow us to burn more gas – and even coal – while reducing carbon dioxide emissions. It is certainly an attractive concept, but it comes at a cost, and no-one has yet turned it into a successful process that can be built into power stations on a routine basis. The capturing part is quite straightforward. Flue gases from burning fossil fuels are passed through a solution of amines that combine...

At the recent G20 meeting in Hangzhou, Presidents Obama and Xi announced that they would be ratifying the climate deal reached in Paris last December. Superficially, this is a big deal – if the two largest global emitters of carbon dioxide are prepared to sign up to this agreement, others will surely follow – but is it really going to make a difference? The main reason this is significant is that, for the first time, it potentially brings all countries into a global agreement to reduce emissions. The Kyoto Protocol, the only previous binding commitment, included only industrialised...

For most of us, it’s back to work, with summer receding fast. With autumn and winter just round the corner, our thoughts will turn from keeping cool to keeping warm. Energy prices and security will be priorities once again. The UK is one of a number of countries apparently set firmly on a path to rely increasingly on renewable energy sources. In practice, this means the focus is firmly on the electricity generating sector, where such a transition can in principle be made with least difficulty. Transport is rather more problematic, although the powers that be retain a touching faith in...

Although so much effort is focussed on renewable energy these days, continued expansion of wind and solar energy cannot for the foreseeable future provide the basis for a secure and affordable energy supply for a modern economy. This is clear to anyone taking an objective view of the overall energy system, but apparently not to politicians. There is a school of thought that believes politicians signing up to the EU’s original 20:20:20 targets – 20% emissions reduction, 20% energy efficiency improvement and 20% share of renewable energy by 2020 – thought the renewables target applied to...

A reliable energy supply has always been a prerequisite for a modern industrial society. Lenin – certainly interested in power in all its forms – once said “Communism is Soviet power plus electrification of the whole country”. In today’s world, there seems to be a move towards the second aim, although hopefully not the first. Electrification is a large part of the proposed plan to reduce carbon dioxide emissions and mitigate future climate changes in many countries. Enthusiasts see a future where cars are battery powered and domestic gas heating systems have been replaced by electric...

Electric cars are touted as the vehicles of the future, but there are major infrastructure issues to be addressed before they could become the norm. The other option put forward by those who would like to see a replacement for the internal combustion engine is the hydrogen-powered car, using fuel cells to produce its own electricity, rather than storing it in batteries. A decade ago, hydrogen seemed to have an equal chance of becoming the fuel of the future as did stored electricity. Not so now; despite occasional pilot projects – usually involving buses – and handful of concept cars and...
