Green light has been given for the world's largest compressed natural storage plant in Grati, Indonesia, that will feed an adjacent 300MW gas-fired power plant, operated by state-owned utility PT PLN (Persero). Classification company RINA approved the design of the CNG plant, paving the way for start of construction works.
A proposal to use a gas power plant to support renewables in Colorado, US has been placed with the independent evaluator for the Colorado Public Utilities Commission (CPUC). Xcel Energy representative Gabriel Romero said savings for consumers would come from Xcel replacing its own coal-fired capacity with gas-fired power from an unknown supplier, as "this power plant is offering us a lower power purchase agreement."
Using CO2 to generate natural gas on industrial scales is a step closer thanks to new technology developed by the Austrian firm, Krajete. The process can convert electricity to methane and has passed initial trials demonstrating the potential for industrial production.
Despite the substantial reductions in carbon emissions delivered by the switch from coal to gas generation due to the current boom in US gas production, report by the Union of Concerned Scientists (UCS) suggests there will be a 'gas ceiling'.
As Russia shifts its outlook east and engages with China on a range of deals for oil, coal and power supply China, energy trade between the two neighbouring countries is likely to quadruple by 2025, according to Wood Mackenzie analysts. "If large projects are to be realised, Russia may have to allow deeper Chinese involvement," said Ian Thom, head of Russia upstream research, suggesting an gas supply deal will be reached in the next two years.
Gas-fired power will increase to account for 40 percent of the energy mix in the US market by 2035, spurring a growth in natural gas demand by one third, analysts with the consultancy ICF International forecast. Gas-fired power currently generates 1,000 Terawatt-hours per year (TWh/y) but new ICF figures expect this to double to 2,000 TWh/y.
Funding has been announced to develop new technology focused on carbon capture and storage (CCS) specifically for gas-powered UK plants. A request for proposals has been announced by the Energy Technologies Institute, a public-private partnership, to invest in a project which is expected to start in the middle of next year.
The UK carbon floor price is not sufficient to encourage CCS-retrofitting in fossil plants in the short-term, says Heather Haydock, Practice Director, Energy & Climate Change at Ricardo-AEA. Neither has backloading of carbon permits in EU-ETS has helped to prop up carbon prices beyond €6/ton – too low to incentivise CCS or a switch from coal to gas generation in much of continental Europe.
A pilot power-to-gas (PTG) project in Germany is being undertaken by E.ON, that converts renewable electricity into hydrogen gas. The gas is injected into the regional gas grid, easing the heavy loading of wind and solar power on electric grids, such as is present in Germany and around Europe, at the same time providing 'renewable' gas feed.
UK property developer partners St Modwen and Glenfinnan have joint forces to build a 299MW combined cycle gas turbine (CCGT) power plant, Meaford Power Station, 50 miles south of Manchester, UK. "We are at an early stage of the project and are just about to introduce it to the local community to capture the details of the project," a Meaford Energy representative said.
Fuel cells have traditionally been associated with renewable technologies, as a means of offsetting generation intermittency problems, but as technology has reached maturity the range of applications and technologies has grown. Fuel cells increasingly provide opportunities for distributed downstream electricity, heat and gas generation and support local production, as well as easing grid requirements securing overall supply stability.
Shale gas will bolster security of supply in the UK, displace a proportion of LNG imports and underpin new gas power generation projects. Substantial volumes of shale gas production, however, are not expected to be forthcoming until the mid-2020ies, delegates at the Gas to Power Britain conference learnt.
