Delivering energy solutions that deliver significant carbon emission savings

Renewable Energy Technology

Enhancing Carbon Savings

We continue to research and develop renewable generation technologies that can be adopted or complement heat networks, to enhance their operational performance and significantly reduce carbon emissions. Working with specialist supply chains, we collaborate to determine the sustainability and viability of renewable energy generation technologies that can be used on your project, now and in the future.

Our Technologies

Solar

Solar Photovoltaic (Solar PV) captures the energy in sunlight using photovoltaic cells, which convert light to electrical energy. The technology is dependent on light intensity, not heat or direct sunlight, meaning it continues to generate electricity even on overcast days and in winter.

Energy Storage

Phase Change Materials are ideal for thermal energy storage due to their ability to store heat and release as they transform between solid and liquid states. Alternative phase change materials have the potential to store and release greater amounts of energy and, when used in conjunction with energy networks, can offset peak loads which reduces capital costs and can improve system efficiencies.

Battery Storage

With recent advances in battery technology, battery storage and powerwalls, products have started to enter the energy market and can be used for a number of different applications. These batteries could be used in energy systems in a number of different scenarios such increasing CHP run hours, back up supply, grid services and to maximise solar utilisation.

Fuel Cells

Fuel cells use an electromagnetic cell that converts the chemical energy of hydrogen into electricity via an oxidation reaction.

Solar Thermal District Heating

Solar thermal district heating (STDH) uses large solar collectors to raise water temperature to traditional distribution temperatures for use in district heating networks.

Wind

15% of the UK’s electricity is generated using wind energy which makes it one of the most widely deployed renewable technologies. Wind can play an important part in your energy mix. Low carbon electrical energy can be used to power pumps and other ancillary electrical plant and equipment to help further reduce carbon emissions of heat networks.

Organic Rankine Cycles

ORC is a waste heat process which can improve the efficiency of heat generating technologies such as biomass and combined heat and power. The process converts low-grade waste heat into electricity and can make a significant contribution towards achieving peak efficiency whilst lowering emissions.

Anaerobic Digestion

As bacteria breaks down organic matter, they generate a biogas. This biogas is lower in CO2 than natural gas and can be used to produce low-carbon heat, electricity or combined heat and power. Biogas can be used to power boilers and CHP engines to provide heat and power to energy networks and, due to the low carbon emission factor of biogas, can significantly reduce carbon emissions.
