Sustainable Hydrogen Innovation and Technology
Having just (over-)indulged in the Tokyo Olympics, I was intrigued to read that The Guardian has taken a negative view of the hydrogen-powered Olympic flame. The article warns that the “Olympic flame is a warning sign for [a] hydrogen future”, and brands it with the keyword ‘Pollutionwatch’. Hydrogen and pollution? Notwithstanding my immediate reaction that … Read more
There are several good books out at the moment relating to the problem of climate change, humanity’s emissions and what to do about them. One is by Bill Gates, and his input on the subject is extremely welcome. With his laser focus on getting tasks completed, he says there are only two statistics that matter: … Read more
In my previous article I explained how a ‘convolution integral’ can be used to simulate a constant phase element (abbreviation ‘CPE’, symbol ‘Q’) in the time domain. This is useful, but there is much more to this simple element than meets the eye. Specifically, when combined with a series resistance to form a very basic … Read more
In electrochemistry it is common to come across behaviour that can only be modelled using a constant phase element (CPE). For example, a measurement taken using electroimpedance spectoscopy (EIS) often produces a flattened or depressed semi-circle on a Nyquist plot. This indicates that a form of capacitance is present (coupled with a resistance), but it … Read more
The UK Government has announced that the date from which the sales of all new petrol and diesel cars and vans will be banned is being brought forward by 5 years, from 2040 to 2035. This is good news, but not particularly surprising, since the government has also committed to being carbon neutral by 2050. … Read more
It is with great sadness that their time is Swansea has come to an end but all good things must and all that… Jacobina and Theopolina came to Swansea in search of some lab-based research guidance to help with their PhD studies in Namibia. This is part of the Chem4Energy programme and my trip to … Read more
November the 27th 2019 we went to see the Mynydd y Gwair Wind Farm operated by our collaborators in Innogy. Was a fantastic day out and really insightful to see how the turbines work up close and personal.
The BBC this morning has news of a the UK’s first hydrogen train. This is interesting news, but what’s more interesting is that this is being driven by the UK government’s commitment to phasing out diesel-only trains within the next 20 years. This could end up having a profound effect on hydrogen powered transport of … Read more
We helped out a team of undergrads with cutting their plane on our laser cutter. Well done to them as it looks amazing. https://dunnill.me/wp-content/uploads/2019/04/video-1554292467.mp4
Okay. Hands up everyone who is prepared to give up flying for the rest of their lives? Hmmm. Not very many of you? Now keep your hand raised if you are also prepared to give up driving… …and heating your home… …or buying anything from a shop, or a restaurant, or online. No-one? Well, I … Read more
