Water in abandoned mines holds heat, but how useful is it?

By Julian Singer The water in abandoned coal mines has received increasing interest as a source of residential and commercial heating. There are certainly many such mines in the UK and most of them will contain significant volumes of tepid water, but how much useful heat can be delivered? Two projects at Gateshead and Seaham, [...]

Hydrogen Safety: the results of H21’s Phase 1 study of hydrogen in the gas network

By Julian Singer In May the H21 project released its Phase 1 report on the safety of replacing natural gas (methane) by hydrogen for residential heating. The hydrogen molecule is much smaller than methane so that there are reasons to fear that hydrogen might leak more easily from the gas network. On the other hand, [...]

Heat Wayv, a new way to decarbonise domestic heating

By Julian SInger Heat Wayv is a private UK company developing a system for domestic hot water and space heating using microwave electricity on the same principle as the microwave oven. The company claims that its boilers will be the same size as conventional gas combi-boilers and with a similar fast response time. As a [...]

The H100 Fife project: the first real-life test of hydrogen for residential heating

By Julian Singer The H100 Fife project is designed to be a real life test of the use of hydrogen for heating homes. The idea is to build a facility in Levenmouth, Fife, that will use offshore wind power to generate hydrogen from electrolysers. The hydrogen will be stored on site and used to feed [...]

H21 pushes ahead with examining the feasibility of using hydrogen for heating

By Julian Singer The interest in hydrogen as a carbon-neutral fuel has increased significantly this year, with shares in some of the companies involved rising sharply (Greenbarrel, 28 July). Much of the interest has focused on hydrogen powering vehicles or storing energy. However while hydrogen may be the solution for commercial and industrial vehicles it [...]

What is the full cost of installing a heat pump?

By Julian Singer Heat pumps are expected to play a major role in decarbonising residential heating, which contributes 14 per cent of the UK’s CO2 emissions, about the same as transport. In fact they are nearly the only solution currently available and will remain so unless the gas grid is converted to hydrogen. But what [...]

Decarbonising Heat III: the hydrogen solution

The two previous articles on Decarbonising Heat summarised the National Infrastructure Commission (NIC)’s study of the costs of different solutions and looked in more detail into the most effective but also the most expensive of these solutions – heat pumps. This article will look into the other main contender – the use of hydrogen instead [...]

Decarbonising Heat II: heat pumps and hybrid gas-electricity solutions

The previous article on Decarbonising Heat summed up the National Infrastructure Commission’s study of the cost of different solutions to this problem. The most effective, but also the most expensive, was found to be the heat pump. This article will look into the pros and cons of heat pumps, and also into a solution that [...]

Decarbonising Heat I: the NIC estimates the cost

The National Infrastructure Commission was set up by the government in 2015 to give non-ministerial advice on the UK’s infrastructure. It monitors projects and produces studies, and is obliged to give an Assessment once every parliament of future needs. It has about 35 employees and a board who are mainly directors from industry or academics [...]

The DBEIS announces a new scheme to support heat networks

Heating has long been recognised as the most difficult area to decarbonise, so the announcement by the Department of Business, Energy and Industrial Strategy on 11 April of a new scheme supporting heat networks was good news. The scheme will offer grants and loans to both public and private sectors, consumers and public buildings such [...]
