Grass Power

3 August 2019

There is enough grass in Britain to power every household if it were turned into renewable gas, according to Dale Vince, the founder of green energy company Ecotricity, The Stroud-based businessman said that Ecotricity plans to build its first grass-powered energy plant in Hampshire by the end of this year in a move to eliminate the demand for industrial farming waste. The project, which will cost Ecotricity £15m, is primed to be the first major investment by a UK company into this type of energy. “It is relatively new, we can basically make gas and put it into the gas grid in the same way that we can with electricity from renewables,” Mr Vince said.

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.

Solar Plus Storage for Cheshire Social Housing

Cheshire West & Chester Council has announced plans to install solar panels with battery storage technology across two large estates. It has appointed Aberla Renewables, part of the Aberla Group, for the installations which include heating solutions that cover 180 council-owned homes. The team has started surveying properties and the project, which consists of solar panels with a total capacity of 250kW, is expected to be completed next year. The £500,000 project is part of the Low Carbon Housing Support Programme and has been jointly funded by the European Regional Development Fund (ERDF).
Local Energy Network for Cornwall

Hundreds of homes and businesses in Cornwall have started selling electricity to their local energy network and the national energy system in a pioneering move. The trial is the first time that traditional energy users – such as homes, hotels and businesses – have acted as suppliers in a microcosm of a full energy system. The trial harnessed together 100 Cornish homes, fitted with batteries and solar panels, to act as a mini virtual power plant for the local energy network, Western Power Distribution, and the UK’s energy system operator, National Grid. During sunny spells when homes generate more than enough electricity from solar panels they can store the power to use later, or supply the energy system with clean extra power. The homes took part in the trial alongside 150 local businesses, which were prepared to adjust how much energy they used depending on the balance of energy supply and demand on the grid. If wind and solar power output dropped the companies could choose to use less electricity in exchange for a payment from National Grid, or if the local grid had more electricity than it needed the companies could ramp up their energy demand. National Grid already offers to pay firms that own utility-scale batteries to provide a similar service, but the trial is the first time that companies can take part in the same “local energy market” as the network operator. The market was designed by energy giant Centrica and modelled on the same system used to balance energy markets across Europe. The energy companies believe the trial could help create a nationwide chain of flexible smart grids built around clean energy.

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 Sundog, 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.
