An end-to-end, completely self-sufficient smart meter, designed for long term value
the problem
The water sector established 7 themes in the UK 2050 Innovation Strategy. Some of these themes highlight the need to transition to an autonomous, digital infrastructure, necessary to reduce leakage, track water quality, and maintain robustness as climate and demand pressures grow. This is all whilst working towards net zero carbon.
To digitise the clean water distribution network, mass deployment of remote monitoring equipment is required.
The problem is the most cost effective way of powering these devices is with Lithium batteries.
The low energy density of a battery is just enough to satisfy the regulatory minimum for flow, pressure, and water quality logging. This leaves little room to meet stricter data acquisition targets. Furthermore, the sector relies on basic leak detection methods, as innovation is focused on saving battery life instead of sensing performance.
Battery replacement is required every 5 years minimum for DMA logging. This is the factory specification based off testing in perfect conditions. In reality, this is often less, due to cold weather, poor signal connection and software updates. Battery replacement frequency will increase significantly with demand for rich data.
The batteries used are generally both non-rechargeable and non-recyclable. This linear economy approach leads to a high carbon footprint and unsustainable use of precious metals.
Batteries are a stopgap solution designed for short term results. Pressures from population growth and extreme weather events require robust and reliable alternatives that deliver long-term value. The sector is driving this innovation strategy by increasing Amp cycle investment payback periods.
our solution
We believe the answer is with energy harvesting...
The water distribution pipeline network already transmits huge amounts of hydro-kinetic energy. Unlike many alternative clean energy sources, such as wind and solar, the flow patterns are predictable and consistent throughout the year. Best of all, the energy is precisely where you need it when powering pipeline monitoring equipment. So we created a method for tapping into this power source, harvesting as much as is required, wherever it is needed.
the barriers
Energy harvesting is not a new concept, but successful implementation in the water industry is limited. We identified three key barriers, and developed solutions to overcome them:
Installation
Existing solutions require pipeline shut-off, disrupting supply to customers and incurring significant regulatory fines.
Pressure Drop
Harvesting more energy than is required leads to further energy consumption at pumping stations, and increased strain on the infrastructure.
Maintenance
Moving components such as bearings or gears introduce vulnerability to jamming through biofouling, mineral build-up or particulate contamination.
