Strong Gains Drive 8.8% Gain for China CleanTech Index

The August 2014 Performance Report for the China CleanTech Index is now available - please click here to download the report.


The China CleanTech Index recorded a very strong 8.8% gain in August 2014 and outperformed all of its four benchmarks. The best performing sub-indices for the month were the China Efficiency Index with a 13.0% gain and the China Storage Index with an 11.6% gain. The two weakest sub-indices through August were the China Waste Index which recorded a gain of only 4.5% and the China Water Index recording a gain of 5.5%.

The twelve month gain for the China CleanTech Index now stands at 17.7% strongly outperforming the Shanghai Composite although behind the other benchmarks. This twelve month gain is being driven by the China Solar Index (+48.8%), the China Efficiency Index (+38.3%) and the China Wind Index (+22.8%).

TEL unveils DeltaStream tidal device

First published on the Cleantech Investor website, 7 August 2014

Tidal Energy Ltd (TEL) has unveiled a tidal energy generator at Pembroke Port in Wales. The 400kW DeltaStream demonstration device will be installed in Ramsey Sound, Pembrokeshire and will be connected to the grid. The device was unveiled by The First Minister of Wales, the Rt. Hon. Carwyn Jones, who commented that:

“This is a landmark project for Wales, which will not only help us to meet our sustainable energy ambitions, but will also provide significant opportunities for local people and businesses.”


Perovskite solar cell breakthrough at University of Sheffield

First published on the Cleantech Investor website, August 2014

The University of Sheffield has announced that scientists from the Departments of Physics and Astronomy and Chemical and Biological Engineering are the first to fabricate perovskite solar cells using a spray-painting process – a discovery that could help cut the cost of solar power generation.

Efficient organometal halide perovskite based photovoltaics were first demonstrated in 2012. Perovskite combines high efficiency with low materials costs and combined with spray-painting - which has previously been used to produce solar cells using organic semiconductors - a process has been developed to use peroskites in high volume manufacturing.

The Perovskite spray-painting techniques waste very little of the perovskite material and can be scaled to high volume manufacturing – similar to applying paint to cars and graphic printing. According to lead researcher, Professor David Lidzey:

“This class of material offers the potential to combine the high performance of mature solar cell technologies with the low embedded energy costs of production of organic photovoltaics.”


2014 Ashden Awards - Abundance Generation

22 May 2014

Impax Ashden Award for Energy Innovation - and UK Gold Award Winner

Abundance Generation

Crowdfunding powers a sustainable energy revolution

Abundance Generation is revolutionising the way people invest for their future. Its user-friendly crowdfunding platform lets people take control of where their money is invested by allowing them to put it directly into sustainable energy projects of their choosing. With a minimum investment of just £5, investors get a financial return and the feel-good factor of joining the growing renewable energy movement in the UK. Abundance is also plugging a gap in access to finance for small-scale renewable energy developers, so they can build more projects. So far this pioneering FCA-regulated company has helped over 1,200 people invest more than £5.5 million in renewable energy projects across the UK, with many more in the pipeline.



2014 Ashden Awards

Ashden Sustainability InitiativeFirst published on the Cleantech Investor website, 22 May 2014

The 2014 Ashden Awards winners were announced this evening in a ceremony at the Royal Geographical Society in London which included a speech from Lord Stern.

In total, fourteen sustainable energy enterprises from the UK, Europe, Africa, India and Southeast Asia were recognised at the ceremony for tackling climate change and transforming lives, each receiving a prize of up to £40,000.

Sarah Butler-Sloss, Ashden Founder Director, speaking at the ceremony, identified four key trends in sustainable energy, all of which were reflected in the businesses of the awards winners. The first three are: cheaper solar, sustainable buildings and communications. The fourth reflects the theme of this year's Ashden conference which took place earlier this week, Sustainable Energy for Women and Girls - and has been encapsulated in the Twitter hashtag #volts4women, which has featured in a social media campaign backed by development agencies including DfID and USAID (both sponsors this year).

The UK 'gold' award went to UK company Abundance Generation, which has a crowd funding site for investment in renewable energy and which was the winner of the award for Energy Innovation. The international 'gold' award was won by Infosys, India - which also won the award for Sustainable Buildings.
