ArcVera Renewables, a leading international provider of consulting and technical services for wind, solar and energy storage projects, was enlisted by a major Indian Independent Power Producer (IPP) to analyze wind resource variation cause and effect after an unexpected drop in wind farm energy production in the country. Although variable year-to-year, wind power production in India in Q2-Q3 2020 has been significantly lower than the long-term average production expectations. Based on an analysis of climate records from reanalysis datasets and surface wind observation sites, this event was rare. ArcVera’s experts applied advanced atmospheric science methods to explain the interannual variability anomalies of the wind energy resource in India.  Annual wind farm performance expectations depend on the long-term accuracy of wind energy resource assessment.  Each year, a wind farms’ performance is typically evaluated by its owner and operator stakeholders to make sure that the variations in the production of the wind farm are explained by variations of the actual wind resource. Lower wind resources can result in significant revenue reduction, testing owners’ and investors’ nerves and their seeking of answers to what can be expected for future performance. “Based on a review of meteorological weather records, the low wind speeds were caused by

A ground-breaking project to develop a new way of storing hydrogen in buses has been launched by academics from London South Bank University (LSBU), School of the Built Environment and Architecture . The LSBU project aims to deliver: Improved safety with hydrogen stored at lower pressures in smaller cylinders on buses instead of the large high-pressure cylinders that are currently used. More space on buses because large high-pressure cylinders are replaced by smaller cylinders. Reduced power consumption because the new storage system could provide the bus with cooling power for air conditioning. LSBU researchers will investigate using hydride to absorb, release and store hydrogen. This would remove the need for large high-pressure cylinders which is the way hydrogen is currently stored on buses. LSBU has been awarded £60,000 of government funding from Innovate UK for the project and will work with industry experts in thermal management, Ricardo, on design and analysis in the first phase. This will be followed by the development of a prototype of new hydrogen storage in the second phase of the project. Professor Yunting Ge, LSBU Professor of Building Services Engineering, said, “Hydrogen fuel cell vehicles produce very low carbon emissions and no air pollution which makes them vital to

Reflections on 2020 and Predictions for 2021 Since becoming CEO in December, most of my life has been dominated by Covid-19.  But despite causing many difficulties, the pandemic has brought some good. It has accelerated the pace of change and given us valuable insights into where – and how - we will work in the future, the skills we will need, and the environmental challenges we face. It has also provided distraction from Brexit, which I hope will move the discussion away from its rights and wrongs to focus on how the country can maximise any opportunities in the year ahead. In the new future many people will continue to work from home if they can do so effectively, while offices will become places to meet. At Siemens, like much of the UK business community, we have found that intercontinental flights and getting together in person is not as essential as we thought. We now run strategy workshops and town halls online, and even festivals where we engage with all our employees. I predict that these ways of communicating with each other and groups of people will continue. One of the many benefits of this working model is accelerated decarbonisation, which we urgently need.

Local authority staff numbers fall 20% since 2011 – as demand set to skyrocket New analysis shows ‘Scotland's local authorities do not have the capacity to deal with new renewable generation’ which is required to meet commitments Scotland’s 32 local authorities are facing a planning logjam which will jeopardise the country’s climate targets, new research by industry body Scottish Renewables reveals today (Nov 23). It has found the number of planners employed by councils in Scotland has fallen by 20% since 2011 - but the number of applications they will have to grant must increase if Scotland is to stay on track to net-zero emissions by 2045. The UK must quadruple the amount of renewable electricity deployed by 2050 in order to meet its climate change targets. Scotland’s planning system determines how renewable energy technology can be built, so is critical to meeting that target. Scottish Renewables Chief Executive Claire Mack has described the situation – revealed in analysis published today (Nov 23) – as “a hidden obstacle to net-zero”. She said: “It is quite clear from this research that Scotland's local authorities do not have the capacity to deal with the large number of planning consents which will be required as we shift our energy

How to restrengthen PV manufacturing in Europe PV to contribute significantly to achieving the climate goals ETIP PV’s forecast: Solar PV will supply 70% of the world’s electricity generation The European Technology and Innovation Platform for Photovoltaics (ETIP PV) has successfully finished its first virtual annual conference. The Conference 'I3PV - Integrated, Innovative, Intelligent' has highlighted the latest advances in all major Integrated PV applications and how they will contribute to the energy transition as well as EU-based value creation. By 2050, when the world must achieve carbon neutrality, ETIP PV’s forecast based on conversion efficiency improvements and Solar PV’s declining cost is that solar PV will supply 70% of the world’s electricity generation. We will use solar PV to move, heat, cool, drive eco-friendly industrial processes, and produce fuels. Solar PV will be deployed everywhere, in systems large and small, designed for productivity and aesthetics as required. “Integrated PV” (PV deeply embedded into components used in the building industry or the car industry, for example) will play a key role in this scenario. This will be a profitable market for Europe, with a high potential for growth, which will bring numerous business opportunities. It needs R&D

The energy system is undergoing unprecedented transformation, fuelled by factors such as technological developments, geopolitical shifts and environmental concerns. According to the World Economic Forum, decentralisation is one of the key trends that will accelerate the transition to sustainable energy supply. Decentralisation is often referred to as ‘energy democracy’, as it aims to increase popular participation while advancing renewables as the new source of energy. Here Matthew Stone, chairman at energy decentralisation experts Nextgen Nano, explains why decentralisation will transform the energy sector. An effective energy transition must integrate the three main faces of the energy triangle: environmental sustainability, security and access to resources and economic development. More than 860 million people in developing and underdeveloped countries lack access to energy, according to the World Economic Forum findings, meaning that the demand for secure and affordable power is increasing. At the same time, the findings suggest that people in those countries can ‘leapfrog’ to the final stage of the energy transition, without experiencing the damaging effects of traditional energy. One viable way to do so is through decentralisation and implementation of innovative technologies. Decentralised energy is generated close to where it will be used, rather than at an industrial plant
