A Durham University spin-out that has developed technology capable of generating power without emitting carbon has secured a six-figure investment.

H2CHP has secured the £600,000 cash injection led by Scottish investors Tricapital Angels and involving Sustainable Venture, and Aberdeen's Net Zero Technology Centre X accelerator programme to develop its free-piston engine that is "fuel flexible" - meaning it can generate heat and power efficiently from different clean fuels. The funding will be combined with £1.3m from Innovate UK to develop prototype generators and stage industrial trials.
