Solar Railways

15 February 2017

How can we connect solar photovoltaics (PV) directly to railways to power electric trains? That’s the question my charity 10:10 and researchers at Imperial College’s Energy Futures Lab are trying to answer. Electric trains are by far the best long distance transport mode when it comes to carbon emissions – at least when their electricity comes from renewable sources like solar or wind. But the UK’s ageing power network poses a significant challenges to any bid to decarbonise road and rail that relies on the grid. There are now swathes of the British countryside where it is impossible to plug in any new solar, wind or hydropower without being hit with a whopping bill for the full costs of local network reinforcement. Faced with this constraint, and squeezed by government subsidy cuts, UK solar developers have started to focus on ways to generate power directly for consumption, rather than exporting it to the grid. With the right customers, solar developers can offer lower tariffs than the grid, while still earning more for their power than they would get from exporting it. Solar giant Lightsource, for example, recently signed a 25 year power purchase agreement (PPA) with Belfast airport that underwrote a neighbouring £5m solar farm, using a private wire to supply a quarter of the airport’s electricity needs. As an industrial client with high on-site daytime energy use and a structural reason to stay put, Network Rail has all of the features needed to support this kind of approach.

Solar Schools in Essex

A rooftop solar scheme commissioned for Essex County Council has seen Solarwatt supply complete PV systems for 15 primary school sites. The German manufacturer was chosen after a tendering process, partnering with inverter manufacturer Fronius and mountings supplier Van Der Valk Solar Systems for the project. Eco Energy Environment and Ceetech Electrical were the installation partners, with the project delivered in partnership with facilities management company Mitie.
Potential for Green Jobs in Cumbria

Proponents of Cumbria’s proposed coal mine often point to its potential to create 500 new roles. But the county could create thousands of jobs and attract billions of pounds of investment if it opts, instead, to expand low-carbon sectors. That is according to a new report from local organisation Cumbria Action for Sustainability. The report outlines how 9,000 jobs could be created across the county in low-carbon sectors including renewable electricity generation and distribution; renewable heat; retrofitting buildings and sustainable waste management by 2035. Around half of these roles, the report stipulates, would be based in West Cumbria, where the UK’s first deep coal mine in more than three decades has been proposed. Of the 9,000 roles, renewable energy generation and infrastructure account for the biggest proportion – more than two-thirds. The report states that Cumbria could rapidly expand its onshore and offshore wind sectors, as well as solar, tidal and hydro, with the right support from government and the private sector.
Nottingham’s Net Zero Ambition

Nottingham City Council has been named the overall winner in the Guardian’s Public Service Awards. He Council announced in January that it intended to become the UK’s first carbon-neutral city by 2028. It has already met its 2020 target to reduce carbon dioxide emissions by 26% four years early; more than 40% of all journeys in Nottingham are made on public transport and solar panels have been installed on more than 4,000 council houses. Energy consumption of council buildings has been cut by 39% and it is on track to generate 20% of its energy from low-carbon sources by next year. And last year the Department for Environment, Food and Rural Affairs concluded that the city’s air pollution had fallen so much that a Clean Air Zone was not needed. Making the carbon neutral commitment was only possible, says Sally Longford, the Labour council’s deputy leader and portfolio holder for energy and environment, because of the work that had gone before. “We got a lot of stick over the years. People thought we were anti-car, because we introduced various schemes to try and reduce car usage and congestion.” But it has paid off. “When I was talking to the officers about how far we could push this they were confident we could go further than other councils because of all the work we’d already done.” One policy in particular, its workplace parking levy (WPL), was a “gamechanger” according to Longford. Introduced in 2012, the WPL is aimed at employers providing 11 or more commuter parking spaces, with an annual rate of £415 per space. It is still the only such scheme in the UK and has not only tackled congestion and pollution but netted the council £61m for improving and “greening” public transport. That money has helped with the redevelopment of Nottingham station, an expansion of the tram network that runs on green electricity from the council’s own energy company, and the council’s fleet of 58 electric buses that has reduced carbon emissions by more than 1,050 tonnes. “We have a positive attitude to these things because they pay for themselves,” says Longford. “We’re putting solar panels on anything that doesn’t move, really, because it saves us money in the long run and helps support other work we’re doing.” The energy and transport teams have won funding from central government, Europe and other sources, and the savings the energy team generates means it actually makes a profit for the council that can be used to cross-subsidise crucial departments such as children’s services.
Net Zero Bristol by 2030

Bristol City Council – controlled by Labour – was the first council in the country to declare a climate emergency in November 2018. That motion was unanimously passed and now acts as the foundations for the City’s transformative commitment to become carbon-neutral by 2030. In 2015, Bristol became the UK’s first European Green Capital. And, having already recorded a 71% reduction in carbon emissions from its direct activities against a 2005 baseline – surpassing a target to reduce emissions by 65% by 2020 – it now has the lowest carbon footprint of any UK city. The City’s Energy, Transport and Green New Deal Lead Kye Dudd stresses the importance of the unitary authority continuing to lead the climate movement in a way that he hopes will create something of a domino effect of climate action among businesses, citizens and policymakers alike. “We need to extend our influence into the business sphere and to bring other people with us.” The Council recently partnered with Manchester-based blockchain technology company EnergiMine to reward council employees who partake in sustainable actions by using the EnergiToken (ETK) platform. ETK uses blockchain to incentivise actions that promote energy reduction, clean transport use and social cause initiatives. Employees can now earn tokens to spend on rewards – or donate the equivalent value to a registered charity – by acting in an environmentally sustainable way. Great progress has also been made outside of the Council’s own operations – particularly in the area of renewable energy. More than £50m has been invested in low-carbon and renewable energy projects in the region since 2012, and to great effect: Bristol sourced 21GWh of energy generation from solar, wind and biomass in 2018 – enough to power 24,000 homes for a month. Through the Council’s City Leap Strategy it hopes to attract a further £1bn of global investment in the city. Local partners already supporting the project include the University of Bristol, University of the West of England, Western Power Distribution, Bristol is Open, Invest Bristol and Bath, Bristol Green Capital Partnership and Bristol Energy. The signs are already looking positive: since its launch last year, the City Leap initiative has already garnered interested from almost 200 local organisations, international firms, investors and energy and infrastructure businesses. Dudd notes that district heat networks and community renewable energy projects are two areas where smaller local businesses can get involved. A 5MW community-owned solar project, has installed roof-mounted solar panels on public buildings. And a new network of underground pipes that will deliver affordable, low-carbon heat and energy across the city – is already benefitting more than 1,000 social housing properties and is continuing to expand. The Council voted in October to make Bristol the first UK city to ban public use of diesel cars from its streets to combat air pollution. While still requiring government approval, that scheme is set to start from 2021. Bristol’s Eastville Park is the first of four planned charging hub for the region, each hosting four to eight rapid-charge connections that can charge an EV up to 80% from 30 minutes’ charging. In total, four local authorities will install 120 new or replacement charge point connections across over the next year. The majority of the charge points will be supplied with 100% renewable energy provided by Bristol Energy.
Sunderland goes for Ground Source Heat Pumps

Residents in 364 homes across seven tower blocks in Sunderland are seeing their gas boilers replaced with heat from ground source heat pumps. There will be a ground source heat pump for each flat which will also be connected to a district heating system consisting of ambient shared ground loop arrays. An underground aquifer will provide the heat source for the tower blocks, accessed via open loop boreholes drilled to depths of 60m. The ambient system prevents heat losses, overcoming overheating in the tower block communal areas, and boosts the system efficiency. The independent heat pumps mean that tenants can shop around for their electricity deal, whilst reducing carbon emissions by an estimated 420 tonnes or nearly 70% per year and improving local air quality. Gentoo Group is delivering the ‘Core 364’ project with the support of Engie and ground source heat pump specialists, Kensa Contracting. Work started in October, with all systems expected to be replaced by late Summer 2020. Gentoo’s chief executive officer, Nigel Wilson, said: “This heating system will provide heat and hot water at a much reduced cost, using natural heat from the ground. For more info see the presentati0on made by Kensa to the APSE Energy Summit in October https://www.apse.org.uk/apse/assets/File/Day%202%20-%20Session%205_2%20-%20Matthew%20Black.pdf

There is huge potential to create ‘green’ jobs in Cumbria – employment opportunities that are good for both people and the environment. New research carried out for CAfS shows that the county could benefit from 9,000 new jobs in industries ranging from renewable energy and construction to transport. The findings are shared in their report The Potential for Green Jobs in Cumbria. Published on Friday 12 March 2021, the report will contribute to the crucial opportunity we have to plan for an economic recovery of Cumbria that accelerates the transition to a cleaner, net-zero emissions local economy after the devastating impacts of Covid-19. The report, supported by players of People’s Postcode Lottery, shows that: there are more than 1300 opportunities for green apprenticeship creation over 3 years in Cumbria, spread across the boroughs: Allerdale – 260; Copeland – 160; Barrow – 300; Carlisle – 350; Eden – 80; South Lakes - 160.

Cumbria is one place that could really benefit from a green recovery plan. A better route to economic prosperity after Covid-19 is urgently needed, one that is anchored in the industries of the future, rather than those of the past. A green recovery plan could be built around four key pillars: Cumbria’s rich potential for green economic development; Economic renewal through local net zero plans; Community participation in plans; Investment to make it happen.

Research by Friends of the Earth has revealed that creating 250,000 green apprenticeships leading to jobs including in renewable energy, woodland creation, and peatland restoration, would help address the crises in youth unemployment (that could cost today's unemployed young people £39bn in future earnings), and climate breakdown. Released in March 2021 the report “An emergency plan on green jobs for young people – why and how?” (by Transition Economics for Friends of the Earth) lays bare the scarring economic impact of youth unemployment from Covid-19 on individuals, local authorities, and the overall country. But the research also shows the huge potential for fighting the climate crisis with green jobs country-wide if apprenticeships are given proper government support.

Cumbria Renewable Energy and Capacity Deployment Study A report by sustainable economic and social development consultants, SQW for Cumbria County Council published in August 2011 giving a detailed assessment of the renewable resources available.

The Scope for Renewable Energy in Cumbria is a report published by the precursor body to Britain’s Energy Coast - Cumbria Vision in 2009. This envisioned the creation of almost 8,000 by 2050 from developing renewable energy.

The West Cumbria Economic Blueprint is the plan put forward in June 2012 by Britain’s Energy Coast, a public/private partnership made up of local authorities and nuclear groups in the area.

A Sustainable Energy Agency for Cumbria: Business Plan and Annexes and Supporting Information - commissioned by Cumbria Vision and the North West Development Agency in 2009. A detailed plan for an Energy Agency to promote low-carbon distributed energy and energy efficiency. Cumbria has a huge renewable potential, and a number of leading renewable energy companies including Gilkes and Energy4All. Despite this, it is not as effective as other areas in accessing funding and support for sustainable energy. Unfortunately the idea of the Agency was never taken forward.
