Arguments against FCEVs (Fuel Cell Electric Vehicles)

I've just encountered this interesting article on Clean Technica which presents a number of arguments against Fuel Cell Electric Vehicles (FCEVs).

First, it seems that companies are using natural gas to source hydrogen. That obviously goes against the principle of providing a 'green' vehicle in the first place, and negates it. This is what Julian Cox says on the issue:

There are no such environmental benefits attributable to hydrogen either now or in any foreseeable future economic reality. On the contrary, hydrogen is a gross threat to efforts to tackle emissions as a result of public policies based on a false environmental premise and by grossly misleading advertising combined with incentives targeting consumers most at risk of deception by messaging citing the alleviation of environmental concerns as a value proposition.

The Ford Motor Company says this:

“Currently, the most state-of-the-art procedure is a distributed [on-site] natural gas steam reforming process.…

How far away is grid parity for residential battery storage? (RENeweconomy)
It is now generally recognised that rooftop solar has reached “socket parity” – meaning it is comparable or cheaper than grid prices – in many countries over the last few years. The big question for consumers and utilities is when will socket parity arrive for solar and battery storage?

You can't trust Graham Lloyd on climate change reporting

According to this piece by Roz Pidcock in RE New Economy (originally sourced from Carbon Brief), an article in The Australian newspaper on deep ocean cooling is misleading because it misses out numerous important aspects of the research upon which it was based (conducted by Carl Wunsch of Harvard University).

The article was written by Graham Lloyd who surmises that:

“The deep oceans have been cooling for the past two decades and [so] it is not possible to say whether changes in ocean heat adequately explain the “pause” in global warming”.

Wunsch has now taken The Australian and Graham Lloyd to task on this saying that Lloyd 'cherrypicked' the research and missed key points. In essence, Wunsch's research finds that although some parts of the ocean are cooling, not all of it is. The cooling signal in fact is very weak, while other parts of the ocean provide strong warming indications. The research is therefore very clear: the ocean, overall, is warming.

More than Three Quarters of the Public Back Renewable Energy
Guest post by Eve Pearce
New Government figures show solid support in Britain for renewables despite green efforts coming in for recent tongue-lashings from politicians and sections of the media. The Department of Energy and Climate Change has just released the results of its latest quarterly survey of public attitudes, which showed that 77% of adults support the use of renewable energy sources. This new data is more welcome news after previous figures issued last summer showed growth in the UK's green market, with renewables being the strongest sector.
It might have been expected that public backing would have slumped, following claims from energy giants that green subsidies add to their costs, together with negative comments from ministers. However, the Energy Department's latest summary of key findings, drawn from “wave 8” interviews carried out in December 2013, found the oppo…

Residents Parking Zones - No real other choice

Congestion in Bristol has been atrocious for decades, and it has been one of the issues on which the present Bristol Mayor, George Ferguson, stood for office at the Mayoral elections. Before his election, transport policy in Bristol with regard to measures to reduce congestion was characterised by constant party-political bickering which basically got the city nowhere.
The Mayor has chosen to act fast and decisively with regard to cutting congestion. A central plank of his policy approach has been Residents Parking Zones (RPZs) which aims to cut parking for free in residential streets, which has the effect of clogging Bristol streets with cars thereby adding to congestion and which is also a menace to cyclists and pedestrians alike.
However, the response has been angry and vitriolic with certain districts of the city, particularly Ashley, coming out in open rebellion.
Ideologically driven
The debate quickly became very nasty, leading me to suspect that it was being ideo…
