Renewable Energy

Jag has experience in all critical areas of renewable energy systems. The company is currently building several systems in-house, one a hybrid system and a gasification unit that, once validated, will reduce the need for power from the grid.

  • Vawt systems

    Vertical axis wind turbines have been developed by Jag using the Venturi effect to improve the speed of the turbine and performance. Jag is currently working with a client to develop a microsystem for transport use.

  • Hydro Systems

    Jag has developed several hydro systems over the years and is currently building a hybrid system for use by the company to reduce its dependency on grid supply and make it more sustainable. The system will then be manufactured for sale across the UK.


Energy from Waste

There were 42 energy-from-waste facilities in the UK in 2018, up from 26 in 2014. Together they have a combined operational capacity of handling 12m tonnes of waste a year, a figure that experts expect will rise to nearly 16m by 2022. It is noted that these installations cost up to £500 million to build and require long-term investment for the company owning the incinerator and the local council authority. The use of municipal solid waste (MSW) mass-burn incineration results in a net negative greenhouse gas flux of almost 400 kg CO2 eq/tonne MSW, with equal proportions of power only and CHP incineration capacity.

The WID does not cover the following types of waste-burning plants: Experimental plants are used for research, development, and testing. These are excluded only if they are used to improve the incineration process and burn less than 50 tonnes of waste per year. They are excluded because of the nature of the plant, not because of the types of waste they burn. Plants that burn only waste in gaseous form. However, if a pyrolysis or gasification plant treats solid or liquid waste to produce a gas which is subsequently burned, both the initial unit and the gas combustion unit will be covered by the WID. Plants that do not fit the definition of a technical unit. Plants that do not fit the definition of an incineration plant or a co-incineration plant - for instance, if the primary activity is cleaning or drying equipment which also happens to combust waste, but where any burning of waste is incidental.

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically 700 degrees C), without combustion, by controlling the amount of oxygen and/or steam in the reaction.

Synthesis gas is a mixture of hydrogen and carbon monoxide, in various ratios. The gas often contains some carbon dioxide and methane. It is principally used for producing ammonia or methanol. Syngas is combustible and can be used as fuel. Historically, it has been used as a replacement for gasoline, when the gasoline supply has been limited

Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell— similar to a battery—to produce electricity, water, and small amounts of heat.
