Energy storage system at The Hold in Suffolk
Connected Energy is set to install the E-STOR second life energy storage system at The Hold facility, on the University of Suffolk’s Ipswich campus...

The E-STOR will make energy use on the campus more efficient. Its system, which includes EV chargers, a critical HVAC and a PV, will form a controlled environment for archived materials, including those owned by Suffolk County Council.

Connected Energy’s CEO, Matthew Lumsden, said that the company’s position as an innovator in the second life battery market made its work at The Hold in Suffolk all the more difficult: “Leading the charge on the use of second life batteries meant we had to start developing systems based on a relatively small data set. But having run several systems though various duty cycles over the last few years we are now able to further optimise how the batteries are operated”.

Mr Lumsden also spoke about the energy advantages of using second life batteries over lithium ion ones: “Second life systems can have different objectives. The cost of the batteries is lower than for new lithium ion systems, so the degradation and overall cycle cost is lower. This means that duty cycles that are uneconomic for new systems can be viable for second life systems. The data-based design that has now been undertaken means we can more accurately optimise how the batteries are used within any duty cycle and better manage efficiencies and degradation.”

A representative of Suffolk County Council, Cllr Paul West, a cabinet member with responsibility for Heritage, commented that the new energy storage system will help the council to meet its objectives: “This work builds on Suffolk County Council’s own knowledge base on the operation of energy storage systems across its estate. It is also a significant move in driving down our carbon emissions, as the council aims to lead by example and be a net zero organisation by 2030, following our climate emergency declaration in 201

Major move forward for UK’s nascent marine energy sector

The UK’s nascent marine energy sector starts exporting electricity to the grid as the most powerful tidal turbine in the world begins to generate power

Although the industry is small and the technologies are limited, marine-based energy systems look to be taking off as “the world’s most powerful tidal turbine” begins grid-connected power generation at the European Marine Energy Centre

At around 74 metres long, the turbine single-handedly holds the potential to supply the annual electricity demand to approximately 2,000 homes within the UK and offset 2,200 tonnes of CO2 per year.

Orbital Marine Power, a privately held Scottish-based company, announced the turbine is set to operate for around 15 years in the waters surrounding Orkney, Scotland, where the 2-megawatt O2 turbine weighing around 680 metric tons will be linked to a local on-land electricity network via a subsea cable. 

How optimistic is the outlook for the UK’s turbine bid?

Described as a “major milestone for O2” by CEO of Orbital Marine Power Andrew Scott, the turbine will also supply additional power to generate ‘green hydrogen’ through the use of a land-based electrolyser in the hopes it will demonstrate the “decarbonisation of wider energy requirements.” 

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” says Scott in a statement. 

The Scottish Government has awarded £3.4 million through the Saltire Tidal Energy Challenge Fund to support the project’s construction, while public lenders also contributed to the financial requirements of the tidal turbine through the ethical investment platform Abundance Investment.

“The deployment of Orbital Marine Power’s O2, the world’s most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net zero,” says Michael Matheson, the Cabinet Secretary for Net-Zero, Energy and Transport for the Scottish Government. 

“With our abundant natural resources, expertise and ambition, Scotland is ideally placed to harness the enormous global market for marine energy whilst helping deliver a net-zero economy.

“That’s why the Scottish Government has consistently supported the marine energy sector for over 10 years.”

However, Orbital Marine CEO Scott believes there’s potential to commercialise the technology being used in the project with the prospect of working towards more efficient and advanced marine energy projects in the future. 

We believe pioneering our vision in the UK can deliver on a broad spectrum of political initiatives across net-zero, levelling up and building back better at the same time as demonstrating global leadership in the area of low carbon innovation that is essential to creating a more sustainable future for the generations to come.” 

The UK’s growing marine energy endeavours

This latest tidal turbine project isn’t a first for marine energy in the UK. The Port of London Authority permitted the River Thames to become a temporary home for trials into tidal energy technology and, more recently, a research project spanning the course of a year is set to focus on the potential tidal, wave, and floating wind technology holds for the future efficiency of renewable energy. The research is due to take place off of the Southwest coast of England on the Isles of Scilly
