The fund, formed by France-based utility GDF Suez in May, is focusing on decentralised energy and energy efficiency technology as traditional power generation loses its lustre.

Aquion Energy, a manufacturer of energy storage systems, has raised $24.6m in funding, a recent filing has revealed.

The water purification company's existing investors include Dow, Coca-Cola and Tata.

Total and DuPont both contributed to a $22m round for the company, which develops crops that can be used as biofuel feedstock.

RusHydro, Russia's national hydropower company, has teamed up with the state-backed investment firm for a fund that will invest in power generation projects.

Intel led the round for the power conversion system developer, which is looking to attract more strategic partners.

The solar steam company, which is targeting the oil and gas industry, raised the cash from a round featuring Shell's corporate venturing fund.
