2G Energy Ltd

2G Energy is one of the world’s leading manufacturers of combined heat and power generation systems (CHP) providing a decentralised supply of heat and electricity using reciprocating piston engines that run on hydrogen, biomethane, biogas, sewage gas, landfill gas or natural gas. The systems in the portfolio range from an electrical output of 20 to 4,500 kW. Customers range from farmers in municipalities, the housing industry, commercial enterprises, medium-scale, and big industrial companies to the energy sector. In addition to its headquarters in Heek, located in the "Münsterland" region in western Germany, 2G is represented by subsidiaries in several European countries as well as North America and has about 920 employees worldwide. Since its foundation in 1995, 2G has commissioned more than 8,500 systems throughout the world.

Many energy users are utilising Combined Heat and Power (CHP) systems to supply large proportions of electricity and heat whilst providing considerable financial savings, zero carbon can be achieved by simply changing the gas input to hydrogen.
2G Energy has been installing and operating 100% hydrogen CHPs worldwide since 2014, shaping the world’s energy transition by providing innovative and pioneering projects with their forward-thinking technology.

2G’s standard engines can run on blends of gases, including hydrogen at up to 40%, before a simple engine retrofit is required to accommodate a higher percentage of hydrogen. Hydrogen-enabled CHP systems can use a blend of input gases and enable a gradual entry into the hydrogen economy – the sudden decommissioning or start-up of large infrastructure projects is not necessary – and these systems can reduce operational costs and carbon emissions.

Working in partnership with Altrad Babcock, 2G installed the UK’s first 100% hydrogen CHP solution at Kirkwall Airport in the Orkney Islands. Funded by the Scottish Government, the CHP installation at Kirkwall Airport is part of a series of initiatives led by the European Marine Energy Centre (EMEC) in collaboration with Highlands and Islands Airports Limited (HIAL) to decarbonise the airport. A study undertaken by EMEC found that space and water heating demand in the airport terminal represented the biggest source of greenhouse gas emissions after aircraft operations. Currently deployed as part of an extended trial, the CHP system has been integrated with the airport’s existing heating system to meet some of the heating and power requirements of the main airport building.
