Severn Drives & Energy are working with a leading global technology developer to introduce to the market a cost-effective vanadium flow battery storage solution, being driven to empower a clean energy future for the world.

Today the world is faced with the twin challenges of global warming and air pollution; this destructive combination is damaging and costly in terms of both human health and the environment. The good news is that new solar and wind power installations are now recognized as some of the lowest cost of generation in most parts of the world, and our long-duration, deep-discharge, long-life batteries are the best way to integrate these variable renewable energy sources onto the grid. Unlike other batteries, our systems are safe, reliable, and recyclable.

Our grid-scale energy storage systems provide flexible, long-duration energy with proven high performance. Systems start at 250kW / 1MWh and can be as large as 100MW / 800MWh in size, installed at utility, commercial and industrial sites, in support of solar or wind farms or in isolated microgrids.

Our long-duration systems are ideally suited to stabilize isolated microgrids, integrating solar and wind power in a safe, reliable, low maintenance, and environmentally friendly manner.


Vanadium flow batteries can be discharged over an almost unlimited number of charge and discharge cycles without wearing out. This is an important factor when matching the daily demands of utility-scale solar and wind power generation.


Vanadium flow batteries have a proven life of at least 25 years without degradation in the battery. Annual maintenance is low, and the vanadium electrolyte, which is 40-60% of battery cost, retains its value at end-of life.


Lithium-based batteries have inherently shorter lifetimes and are not well suited for longer duration storage (4+ hours). Vanadium outperforms lithium on depth-of-discharge (DoD), cycle life, and end of life value (lithium carries a disposal cost).

At the end of 25 or more years, our electrolyte can be reused in another battery or recycled for use as commodity vanadium. This is dramatically different to other battery types that ultimately carry a waste disposal cost.

Unlike other battery systems, vanadium flow batteries are a robust product, contains no heavy metals like lead, nickel, zinc or cadmium and the liquid electrolyte in our products is non-toxic, non-flammable and is 100% reusable.

Severn eliminates corrosion risk in firesafe valves for offshore oil & gas.

Severn Glocon Group is extending its range of triple offset butterfly valves with a new solution that avoids galvanic corrosion in saline applications, without compromising firesafe capability.

The OCT®SW innovation was driven by market feedback from offshore oil and gas operators in relation to seawater service valves used for fire safety. It ensures graphite parts – which can increase the susceptibility of neighbouring metals to corrosion when exposed to seawater – do not contact line media.

Seawater service valves play an integral role feeding water in the event of fire on an offshore platform or vessel. Their ability to either supply or isolate sections of the water line is a critical safety feature. Eliminating galvanic corrosion while maintaining firesafe credentials has been an enduring challenge for the industry. Severn’s new valve design overcomes this limiting factor and recently passed fire testing in accordance with the latest editions of API 6FA, API 607 and ISO 10497.

Mark Breese, Group Product Development Manager – Butterfly Valves, says his team focused on fully isolating graphite parts from line media, or removing them from the valve entirely.

“Triple offset valves are generally constructed with graphite packings, gaskets and laminated metal/graphite seals,” Breese explains. “In normal operation this noble material provides good service, but increased risk of galvanic corrosion in seawater applications has been an ongoing concern for offshore operators. Our team overcame significant technical challenges to develop a sustainable solution that removes or replaces graphite. Their success underlines our world-class engineering capabilities and builds on our pioneering oblique cone technology for triple offset valves.”

Granted a patent by the UK Intellectual Property Office in 2018, Severn’s oblique cone technology (OCT®) is central to this new solution. The ‘infinite circle’ geometry of the design enabled the R&D team to develop a hybrid seal technology that eradicates the need for graphite.

To validate integrity, OCT®SW valves are exposed to a stringent fire testing procedure, involving a 30-minute burn where they are bathed in flames. Valves are monitored for leakage throughout the process. After a forced cooldown period, they undergo further seat and external leakage testing, and operational capability is also verified. The process is designed to simulate the time required to extinguish a fire, ensuring the valves can perform during and after an incident.

“This is a landmark development which offers benefits for many firesafe applications, not just seawater service,” Breese continues. “The team took steps to ensure the solution is compatible with additional control valve features such as anti-cavitation or low-noise trims, extending its potential use beyond isolation service. It can also be retrofitted into valves already in operation.”

Ground-breaking wave energy converter prototype reaches the FaBTest nursey site in Falmouth for sea testing.

SG Technologies designed and manufactured the ground-breaking wave energy electrohydraulic control system at the heart of this quarter-scale device which has been created by Marine Power Systems. Following successful completion of pre-deployment tests in Milford Haven, it was towed to Falmouth for full deployment.

WaveSub harnesses energy from the continuous orbital motion of waves under the surface of the sea. It comprises an array of floats and tether lines which are connected to hydraulic generators. As the floats move with the waves, hydraulic energy is created. This is smoothed via the hydraulic circuit and turns an electrical generator with grid-compatible electrical output.

Growth in the renewable sector continues to gather pace, and Severn is committed to developing new technologies that help capture energy from natural sources.

Severn manufactures and supports high quality valves for the energy industries. Its control, choke and small bore subsea valves are pre-eminent in the global market, underpinning the reliability and high performance of business-critical client infrastructure.

Severn’s global reach, technical prowess, and collaborative approach – all founded upon a heritage of British engineering excellence – help to assure production continuity for clients and reduce the prospect of costly downtime. 

Its understanding of the life-cycle of assets positions Severn to offer end-to-end engineering solutions, enabling clients to meet their core imperatives: safe operations and minimum downtime.

Severn extends its reach.

Severn’s model for establishing world-class valve engineering skills locally in key production markets that have previously lacked investment continues to reap rewards. This led to the recent launch of GenesisSG in Ghana, a relative newcomer to the oil and gas market that is seeking to ramp up production and push for energy independence.

The overarching goal is for Severn to extend its reach and to address capability gaps, enhancing the long-term prospects of regions that have faced socio-political issues or experienced rapid growth of new processing industries. It involves blending Severn’s advanced valve engineering expertise with infrastructure support and knowledge of local partner organisations. This is applied strategically to facilitate better valve population management alongside training and development of local engineers.

Successful ventures in Iraq and Kazakhstan have led to significant performance improvements for organisations including Basra Gas Company. A small team of valve experts from overseas mentors local engineers, progressively handing over greater levels of responsibility. The ultimate intention is to redeploy the expats to new markets requiring support, once local engineers are fully empowered to handle the technical demands of proactive valve management.

The approach is now being used as a blueprint for the rollout of similar ventures in other markets that require specialist valve engineering support so Severn extends its reach.
