Solar power - a snapshot of the industry in 2012
01 November, 2013
An International Energy Agency (IEA) report provides a snapshot of the global PV industry in 2012.

Why CFB scrubbing has stepped out in front
14 October, 2013
Power plant emissions limits are becoming ever more stringent and regulators are showing increasing interest in expanding the scope of regulation, eg to metals. This regulatory context, combined with concerns about water scarcity, is driving increased interest in dry FGD options, in particular circulating fluidised bed based technologies, which are now proven at large scale - over 520 MWe at Basin Electric's Dry Fork plant - and at a wide range of sulphur levels. CFB is now increasingly favoured for retrofit projects in the USA, for example.By Robert Giglio

Overpowered by the sun
14 October, 2013
For a brief moment in April combined wind and solar power production in Germany peaked at 35.6 GW. The event confirmed what is already suspected - that the grid is as yet not 'smart' enough to deal with such high levels of intermittent generation.By Danny Stephens

Offshore transmission: the licensing regime explained
12 July, 2013
In January 2013, several aspects of the regulatory regime underpinning the connection of offshore wind assets to the UK's onshore electricity network were criticised by the UK's Public Accounts Committee.

NET Power's CO2 cycle: the breakthrough that CCS needs
10 July, 2013
NET Power's proposed oxyfuel power plant technology, with supercritical CO2 as the working fluid in a radically new cycle, makes carbon capture an inherent feature of the process, not an add-on with very large parasitic loads, as with "conventional" CCS approaches. The result: 100% carbon capture with extraordinarily high target efficiencies, 58.9% LHV for gas, 51.44% LHV for coal.

Energiewende: the view from Rosenheim
08 July, 2013
Distributed CHP based on efficient and flexible gas engines, with plenty of thermal storage, looks like a promising way forward for Germany’s municipality-owned power companies.

MicroCHP and the municipalities
08 July, 2013
Report on the progress being made in Germany in the commercialisation of fuel cell based micro CHP.

Breaking ground on a ground-breaking new line
07 July, 2013
Some 6500 km of power distribution lines run through the Ruhr city of Essen. But another, rather special, kilometre will soon be added to the electricity grid.

Largest solar towers will be in California
07 July, 2013
Abengoa and BrightSource Energy have entered into a partnership to build the world's two largest solar power towers

Achieving high wind status in a single bound
11 April, 2013
On 13 December last year the CEZ Group's Fantanele-Cogealac wind park was declared to be in full operation. It has taken two and a half years to complete, is the largest onshore wind farm in Europe to date, and the largest in the world outside the United States. It takes Romania's renewables capacity from an insignificant 14 MW to a respectable 600 MW+.

Nemo may not be fictional for much longer
09 April, 2013
A key milestone in the Nemo project to link the UK and Belgian grids was achieved at year end when National Grid Nemo Link applied for an electricity interconnector licence, paving the way for the start of the procurement process. Staff report

Nexans' core concept: less sag, more capacity
01 March, 2013
A core of high-strength carbon fibre composite is the key to Nexans' new Lo-Sag conductor.

Coal still king, at least outside the OECD
01 February, 2013
Paradoxically, in a world apparently preoccupied with the curbing of CO2 emissions, the International Energy Agency's latest projections show global coal consumption increasing substantially over the next five years, mainly due to demand growth in China and India.

Why Drax has a growing interest in full conversion
01 January, 2013
Concrete manifestations that the 4000 MW Drax coal fuelled power station in the UK is well on the way to further increasing its biomass burn are now clearly visible on the power plant site. In the form of new biomass storage domes. These are being built under a contract with Shepherd announced in March 2012. That announcement talked about spending £50 million in 2012 to secure full benefit from the site's existing co-firing facilities and producing "up to 20% of the power station's output from sustainable biomass."

Dealing with the 50.2 Hz problem
01 January, 2013
Work is now underway in Germany to address the "50.2 Hz problem". This arises because much of the existing PV generating capacity in Germany, a very substantial quantity, is designed to cut out should grid frequency rise to 50.2 Hz, for example due to a surplus of power on the system, potentially leading to a major grid disruption.

Reality kicks in at GTC 2012, with reports of plant start-ups
01 January, 2013
Report from the Gasification Technologies Conference 2012, Washington, DC.

Revolutionary new WTG blade: it's a fabrication
01 January, 2013
GE has revived a century old manufacturing concept used for making the wings of early biplanes. It has applied it to the construction of modern wind turbine blades. It entails covering a light blade frame with a tensioned fabric. This new approach could significantly reduce production costs and make wind power more economically competitive.
